Terms of Service

Last updated: October 16, 2026

These Terms of Service ("Terms") govern your purchase and use of Prologs electronic logging devices ("Devices"), cables and accessories, the Prologs mobile application and web portal (the "Software"), and related monthly subscription services (together, the "Services"). By placing an order through the Order Form on www.prologs.us, signing a customer agreement, or using the Services, you agree to these Terms.

1. Definitions

• "Prologs," "we," "us," "our": the ProLogs brand and service, operated by Prologs Solutions LLC, which provides the Software and Devices.
• "Pro Solution": Pro Solution, LLC, a Delaware limited liability company, the authorized reseller, billing agent, and collection agent for Prologs.
• "Customer," "you," "your": the motor carrier, company, or individual that places an order or uses the Services.
• "Order Form": the online equipment order form on www.prologs.us.
• "Customer Agreement": the Agreement for Use of Equipment and Services signed by you, if any. If these Terms conflict with a signed Customer Agreement, the signed Customer Agreement controls for that conflict, and the rest of these Terms still apply.

• "Payment Method": a credit or debit card, or a U.S. bank account used for ACH debit, that you save with our payment processor.

2. Pro Solution, LLC as Billing Agent and Merchant of Record

2.1 Pro Solution, LLC processes and bills all charges on behalf of Prologs, including Device and cable prices, shipping, sales tax, card processing fees, monthly subscription fees, late fees, and collection costs.

2.2 All amounts you owe are owed to, and payable directly to, Pro Solution, LLC.

2.3 Invoices, receipts, payment confirmations, and payment links come from Pro Solution, LLC or from our payment processor on its behalf. Pro Solution, LLC is the entity that appears on your card or bank statement.

2.4 Billing contact: accounting@prosolutionllc.us. Product, technical, and general support: Prologs, (630) 538-3515, info@prologs.us.

2.5 You agree that payment to Pro Solution, LLC satisfies your payment obligation to Prologs.

3. Eligibility and Accounts

3.1 The Services are for business use by motor carriers and fleets in the United States. You represent that you are at least 18 years old and have authority to bind the company placing the order.

3.2 You must provide accurate company name, USDOT number, contact name, phone, email, billing, and shipping information, and keep it current. We may refuse or cancel orders containing inaccurate or unverifiable information.

3.3 You are responsible for activity under your account and for keeping login credentials confidential, including those issued to your drivers and staff.

4. Ordering Equipment Online

4.1 Placing an order. You may order Devices, cables, and accessories through the Order Form. Your submission is an offer to purchase. It is not accepted until we confirm it by sending an order confirmation or by shipping the equipment.

4.2 Acceptance and cancellation by us. We may decline or cancel any order, in whole or in part, for reasons including product unavailability, pricing or description errors, suspected fraud, failed payment, inaccurate information, or an outstanding unpaid balance. If we cancel an order for which you have already been charged, we will refund the amount charged.

4.3 Cancellation by you before shipment. You may cancel an order at any time before it ships by contacting us at (630) 538-3515 or info@prologs.us. If the order has not shipped, we will cancel it and refund the amount charged to the original Payment Method, including any card processing fee. Once an order has shipped, it can only be returned under Section 9.

4.4 Immediate charge. When you submit the Order Form and complete checkout, your Payment Method is charged immediately by Pro Solution, LLC through Stripe for the order total shown at checkout.

4.5 Consistency with the Customer Agreement. Under the Customer Agreement, equipment is billed on the ship date (or on the pickup date for office pickup). For online orders, the order total is charged at checkout and treated as billed on the ship date. If an order cannot be shipped, Section 4.2 applies and the charge is refunded.

5. Prices, Fees, and Taxes

5.1 Current equipment prices. Prices are displayed on the Order Form at the time of order. As of the date of these Terms, the prices in the Customer Agreement are: 88 Series Device, $120.00 each; 87 Series Device, $140.00 each; required cable, $20.00 each. The price shown at checkout controls for your order.

5.2 Sales tax. Sales tax at 6.25% applies to Devices and cables for all customers, regardless of ship-to state. Sales tax does not apply to shipping charges. Tax rates and taxability may change as required by law, and we will charge the rate that applies to your order.

5.3 Shipping (billed after shipment). Shipping, by ground or overnight service as you select, is charged at the actual carrier cost. Because the exact cost is known only when your order is shipped, shipping is not included in the order invoice you pay at checkout. After your order ships, Pro Solution, LLC will bill the actual shipping cost, either by charging your saved Payment Method or by sending you a separate shipping invoice, which is due within 1 day. By placing an order and checking the authorization box on the Order Form, you expressly consent to and authorize this post-shipment shipping charge. You are responsible for all shipping, handling, packaging, delivery, and transportation charges. Unpaid shipping invoices are subject to the late payment and suspension terms in Section 7.

5.4 Card processing fee. Payments by credit or debit card carry a processing fee of approximately 3% of the amount charged. The fee is shown before you confirm payment. ACH bank debit carries no processing fee.

5.5 Pricing changes. We may change prices, fees, and subscription rates at any time. Changes to equipment prices apply to new orders only. Changes to your monthly subscription rate will be communicated by email at least 30 days before they take effect, and your continued use after that date means you accept the new rate.

5.6 Currency. All payments must be made in U.S. dollars.

6. Payment, Invoices, and Due Dates

6.1 Invoices. Equipment orders and subscriptions are invoiced by Pro Solution, LLC and sent by email. Invoices are due within one (1) day of the invoice date, and payments are due upon receipt as stated in the Customer Agreement.

6.2 Accepted payment methods. Online orders may be paid only by credit or debit card or ACH bank debit (processed through Stripe), or by Zelle to subbillingpro@gmail.com with the invoice number in the memo. Checks and wire transfers are not accepted for online orders.

6.3 Payment processor. Payments are processed by Stripe, Inc. We and Pro Solution, LLC do not store your full card number or full bank account number. See our Privacy Policy.

6.4 Late fees. Late payments may incur a late fee of 1% per month on overdue amounts. If invoices remain unpaid for two (2) consecutive months, Pro Solution, LLC may impose a service charge of 1.5% per month (or the maximum allowed by law), with a minimum charge of $2.00, and may recover attorney fees, collection costs, and expenses incurred in enforcing these Terms.

7. Authorization to Save Payment Method and Charge Automatically

7.1 Saving your Payment Method. By providing card or bank account information at checkout or in your portal, you authorize Pro Solution, LLC, on behalf of Prologs, and Stripe to securely save your Payment Method and to use it for the charges described in these Terms.

7.2 Recurring and automatic charges. If you authorize automatic payment (by selecting the option at checkout, signing the Customer Agreement payment authorization, or accepting an authorization in your portal), you authorize Pro Solution, LLC to charge your saved Payment Method for: (a) your monthly ELD subscription fees on or about the invoice date each month; (b) equipment, tax, and card fees on orders you place, and the shipping cost billed after each order ships; (c) late fees, returned payment fees, and other amounts due under these Terms; and (d) any adjustment for additional Active Devices. You agree that no further notice or authorization is needed for each charge, other than the invoice or receipt we send you.

7.3 ACH debit authorization. If you select ACH, you authorize Pro Solution, LLC to initiate electronic debit entries to the U.S. bank account you provided, and, if necessary, credit entries to correct erroneous debits, in accordance with the rules of the National Automated Clearing House Association (Nacha). This authorization remains in full force until you cancel it as described in Section 7.6. You confirm that you are an authorized signer on the account and that the account is a business account used for business purposes.

7.4 Card authorization. If you select a card, you authorize Pro Solution, LLC to charge the card for the amounts described in Section 7.2 and to retain the card details with Stripe for future authorized transactions on your account until you cancel. We may use account updater services offered by card networks to keep your card current.

7.5 Timing. Monthly invoices are generally issued between the 1st and 5th day of each calendar month, in arrears, and cover services provided during the preceding month. For customers enrolled in ACH or automatic payments, the charge or debit is generally processed on the same date the invoice is issued. ACH debits can take several business days to settle.

7.6 Revoking authorization. You may revoke the authorization or change your Payment Method at any time by written notice to accounting@prosolutionllc.us or by updating the Payment Method in your portal. We need a reasonable opportunity to act, generally at least three (3) business days before the next scheduled charge. Revocation does not cancel amounts already owed, and you must provide another payment method or pay each invoice by the due date. Revoking authorization does not terminate your subscription (see Section 11).

7.7 Failed or returned payments. If a card is declined or an ACH debit is returned for any reason (including insufficient funds, closed account, or an unauthorized-debit claim you did not coordinate with us), then: (a) we may retry the charge; (b) we may charge a returned or failed payment fee of $25 plus any fees our bank or processor charges us; (c) late fees under Section 6.4 apply; and (d) we may suspend the Services under Section 8 and require payment by a different method. You are responsible for all amounts due even if a payment is returned.

7.8 Notice of changes. We will email you before changing the amount of a recurring charge, other than changes caused by the number of Active Devices or by taxes and fees already described in these Terms.

8. Suspension and Collection for Non-Payment

8.1 If any amount is not paid when due, Pro Solution, LLC and Prologs may, after notice by email, suspend or terminate your Services (including access to the Software and Devices), place a hold on new orders, and refer the account for collection.

8.2 Suspension of the Services does not stop subscription charges accruing on active Devices unless and until you terminate under Section 11 or we agree otherwise. Suspension of ELD service may affect your ability to comply with hours-of-service rules. You are solely responsible for having a compliant alternative, such as paper logs as permitted by FMCSA, during any suspension.

8.3 We will restore Services after full payment of overdue amounts and applicable fees. We may require a different Payment Method.

9. Shipping, Delivery, and Risk of Loss

9.1 We ship Devices to the address you provide, using carriers such as UPS or FedEx. Delivery dates are estimates and are not guaranteed.

9.2 Office pickup may be available by arrangement. Equipment is billed on the pickup date.

9.3 Title and risk of loss for equipment pass to you when we deliver the equipment to the carrier (or hand it to you on pickup). If a shipment is lost or arrives damaged, notify us within five (5) days of the delivery date shown by the carrier (or the expected date for a lost package), and we will help file a carrier claim and, where the loss is covered, replace or refund the order. We do not separately insure shipments beyond the carrier's standard declared-value coverage (generally up to $100 per package).

9.4 You must check the contents when you receive a shipment and report any shortage or visible damage within five (5) days.

10. Returns, Refunds, Warranty, and Defective Devices

10.1 Returns. Unused Devices and cables in original condition and packaging may be returned within 30 days of delivery. Return requests must be made to info@prologs.us or (630) 538-3515, and you must obtain a return authorization before shipping anything back. Returned items are inspected, and a restocking fee of 15% applies to non-defective returns. Return shipping is at your cost unless the item is defective. Sales tax is refunded in proportion to the refunded equipment amount. Original shipping charges and card processing fees are not refunded on non-defective returns.

10.2 Refunds. Approved refunds are issued to the original Payment Method by Pro Solution, LLC, usually within 5 to 10 business days after we receive and inspect the return. Your bank may take additional time to post the credit.

10.3 Limited warranty. Devices include a one-year limited warranty from the ship date against defects in materials and workmanship under normal use. Cables and accessories include a ninety (90) day limited warranty from the ship date.

10.4 Defective devices. If a Device fails within the warranty period, contact support. We will troubleshoot and, if the Device is defective, repair or replace it at our option, at no charge for the replacement Device. We may require return of the defective Device. Replacement does not extend the original warranty period beyond the remainder of the original term (or 90 days, if longer).

10.5 Exclusions. The warranty does not cover damage from misuse, accident, abuse, water or fire damage, unauthorized modification, improper installation, use with incompatible equipment, theft or loss, or normal wear. Repair or replacement outside warranty coverage is at your cost.

10.6 Disclaimer. EXCEPT FOR THE LIMITED WARRANTY ABOVE, DEVICES AND SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE", AND WE DISCLAIM ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE FULLEST EXTENT PERMITTED BY LAW.

11. Monthly ELD Subscription

11.1 A monthly ELD subscription is mandatory for every Device. Devices cannot be used with the Software without an active subscription.

11.2 The monthly fee is the rate stated in your Customer Agreement or order confirmation, per Active Device, until termination. A Device used for five (5) days or more in a calendar month is an Active Device and is subject to that month's fee.

11.3 Subscriptions are billed monthly by Pro Solution, LLC as described in Section 7.5, and may be charged automatically to your saved Payment Method if you have authorized it.

11.4 Termination. Either party may terminate the subscription by thirty (30) days written notice. Notice to terminate should be sent to info@prologs.us with a copy to accounting@prosolutionllc.us. Fees continue through the end of the notice period. We may terminate or suspend immediately for non-payment, material breach, unlawful use, or misuse. Subscriptions do not automatically renew for a fixed term beyond the monthly billing cycle.

11.5 On termination you must stop using the Software, return or properly dispose of equipment where required by a written agreement, and pay all outstanding amounts. Purchased Devices remain yours, but will not function with the Software without a subscription. Data retention after termination is described in our Privacy Policy.

11.6 Rented Hardware. If any Device was provided to you as rented hardware under an Order Form or Customer Agreement, you must return it to the address we designate, in working order with normal wear and tear excepted, within ten (10) days after the Software is disconnected. If you do not return rented hardware, you will be charged the Device purchase price in our then-current price list. Fees continue to accrue until the Software is disconnected and the rented hardware is received by us.

12. Use of the Services and Restrictions

12.1 We grant you a limited, non-exclusive, non-transferable, revocable license to use the Software for your internal business operations during your subscription.

12.2 You agree not to: modify, reverse-engineer, or tamper with the Software or Devices; resell, lease, sublicense, or distribute the Services without written consent; introduce malicious code; extract data by automated means without permission; use the Services for unlawful purposes or to build a competing product; or install a Device in a vehicle you are not authorized to operate.

12.3 You must install and use Devices according to our instructions. Drivers must not use mobile devices while driving in violation of applicable law. You are responsible for your drivers' use of the Software.

12.4 You must keep the Software and any mobile apps updated and keep vehicle information, driver accounts, and carrier information accurate.

12.5 Competitors. You may not use, install, or access the Software if you or any of your affiliates is a competitor of Prologs.

12.6 Support. We provide support for the Software during business days. We may schedule downtime for maintenance or upgrades and will make reasonable efforts to announce it by email. Support does not cover problems caused by your misuse or alteration of the Services, by modifications we did not make or authorize, or by combining the Software or Devices with software or hardware we did not supply or identify as compatible.

12.7 Third-party services. The Software includes content, features, and services provided by third parties. Where you activate a third-party service, you consent to sharing the information needed for it to work, including personal information of your drivers. Use of Google Maps in the Software is subject to the Google Privacy Policy, the Google Maps/Google Earth Additional Terms of Service, and the Google Terms of Service. We are not responsible for third-party sites or services linked from the Software.

12.8 Additional services. Custom development, extended support, or other additional services require a separate written agreement that describes the services, delivery milestones, and payment. Intellectual property developed as part of additional services belongs to Prologs unless that agreement says otherwise.

13. FMCSA and Regulatory Compliance

13.1 Prologs devices and software are intended to meet the technical requirements of FMCSA's ELD rule (49 CFR Part 395, Subpart B). Prologs (ELD name "ProLogs," manufacturer Prologs Solutions, LLC) is listed on the FMCSA registered ELD list under ELD identifier 101PRO. FMCSA registration is a self-certification by the provider and does not mean FMCSA endorses the product.

13.2 You remain solely responsible for compliance with the hours-of-service, record-keeping, vehicle inspection, driver qualification, IFTA, and all other federal, state, and local regulations. The Services are a tool and do not guarantee compliance, avoid violations or fines, or replace your judgment or your drivers' duty to maintain accurate records.

13.3 You are responsible for ensuring drivers are trained to use the ELD, can produce required records and instruction cards at roadside, know the malfunction procedures, and correctly certify and edit logs. Data transfers to FMCSA or officers are initiated by the driver or authorized user.

13.4 You are responsible for entering correct vehicle, driver, and carrier information, and for resolving unidentified driving, edits, and malfunction or data diagnostic events.

13.5 Cellular, GPS, and network connectivity is outside our control and the Services may be interrupted or inaccurate in areas of poor coverage.

14. Data and Location Information

14.1 Devices and apps collect vehicle and driver data such as GPS location, engine data, speed, odometer, hours of service records, and diagnostics, which we process to provide the Services and meet FMCSA requirements. See our Privacy Policy.

14.2 You are responsible for providing any notices and obtaining any consents required from drivers and employees whose data is collected through the Services, and for lawful use of location data.

14.3 You own your customer data. You grant us and Pro Solution, LLC a license to process it to provide the Services, comply with law, support you, and improve and secure the Services using aggregated or de-identified data.

14.4 We may disclose data as required by law, subpoena, or FMCSA or roadside inspection requirements, or to protect rights and safety.

15. Chargebacks and Payment Disputes

15.1 If you have a billing concern, please contact accounting@prosolutionllc.us before disputing a charge with your bank, so we can resolve it quickly.

15.2 If you file a chargeback, ACH dispute, or payment reversal, we may suspend the Services and hold new orders while it is reviewed, and we may submit evidence (such as your order, acceptance of these Terms, delivery confirmation, and usage records) to the bank and processor.

15.3 If a chargeback or reversal is decided in our favor, or is withdrawn, you must pay the amount in full along with any dispute or processor fees charged to us, and applicable late fees. Fraudulent or abusive disputes are a breach of these Terms.

16. Intellectual Property

16.1 Prologs and its licensors own the Software, Devices' firmware, trademarks, logos, documentation, and all related intellectual property. No ownership rights transfer to you, other than title to the hardware you purchase.

16.2 Feedback you provide may be used by us without restriction or compensation.

17. Confidentiality

Each party agrees to protect the other's non-public business information received in connection with the Services using reasonable care and to use it only for purposes of these Terms, for seven (7) years after disclosure or until the information becomes public through no fault of the receiving party, except where disclosure is required by law.

18. Disclaimer of Warranties

The Services depend on third-party networks, satellites, and equipment. We do not warrant uninterrupted, error-free, or fully accurate service, or that GPS or telematics data will always be available or precise. See also Section 10.6.

19. Limitation of Liability

19.1 TO THE FULLEST EXTENT PERMITTED BY LAW, PROLOGS SOLUTIONS LLC, PRO SOLUTION, LLC, THEIR AFFILIATES, OFFICERS, EMPLOYEES, AND REPRESENTATIVES WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, LOADS, DATA, OR BUSINESS OPPORTUNITIES, FINES, CITATIONS, OR OUT-OF-SERVICE ORDERS, EVEN IF ADVISED OF THEIR POSSIBILITY.

19.2 OUR TOTAL LIABILITY FOR ALL CLAIMS RELATED TO THE SERVICES AND THESE TERMS WILL NOT EXCEED THE AMOUNTS YOU PAID FOR THE SERVICES OR EQUIPMENT GIVING RISE TO THE CLAIM IN THE SIX (6) MONTHS BEFORE THE CLAIM AROSE.

19.3 Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

19.4 No claim may be brought by either party more than one (1) year after the cause of action arose.

20. Indemnification

You agree to indemnify and hold harmless Prologs Solutions LLC, Pro Solution, LLC, and their affiliates, officers, employees, and representatives from damages, costs, liabilities, claims, and expenses (including reasonable attorney fees) arising from your breach of these Terms or the Customer Agreement, violation of law (including FMCSA, DOT, or other regulations), misuse of the Services, infringement of third-party rights, or your drivers' acts. This section also applies to the liability release in your Customer Agreement.

21. Governing Law and Disputes

21.1 These Terms are governed by the laws of the State of Illinois, without regard to conflict-of-law rules.

21.2 You agree to first try to resolve any dispute informally by contacting us. Any dispute that is not resolved within 30 days will be resolved by final and binding individual arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, seated in DuPage County, Illinois, except that either party may bring an individual claim in small claims court or seek injunctive relief for misuse of intellectual property. To the extent any dispute is permitted to proceed in court, it will be brought only in the state or federal courts located in DuPage County, Illinois, and you consent to their jurisdiction.

21.3 Class action waiver. You and we agree that each may bring claims against the other only in an individual capacity and not as a plaintiff or class member in any purported class, collective, or representative proceeding.

22. Changes to These Terms

We may update these Terms with notice to you, such as by posting on www.prologs.us or emailing you. Changes apply to future orders and to your use after the effective date. If you do not agree to a change, you may terminate under Section 11.4.

23. General

23.1 These Terms, the Order Form confirmation, the Customer Agreement (if any), and the Privacy Policy are the entire agreement regarding the Services and replace prior terms.

23.2 If a provision is unenforceable, the remainder stays in effect. Our failure to enforce a right is not a waiver.

23.3 You may not assign these Terms without our written consent. We may assign them, including to Pro Solution, LLC or an affiliate or successor.

23.4 Neither party is liable for delays caused by events beyond reasonable control, including carrier delays, network outages, supply shortages, or natural events. This does not excuse payment obligations.

23.5 You consent to receive notices, invoices, and receipts electronically by email and through the portal.

23.6 Sections that by nature should survive termination (payment, indemnification, liability, confidentiality, governing law) survive.

23.7 Acceptance without an Order Form. If we do not receive a signed Order Form or Customer Agreement within thirty (30) days after you receive Devices, you are deemed to have accepted these Terms by keeping or using the Devices.

23.8 Acknowledgement. You acknowledge that you have read and understood these Terms, that you have been advised to review them regularly and to obtain independent legal advice before accepting them, and that you have done so or chosen not to.
