Terms of Service
These Terms of Service ("Terms") govern your use of CarSignal. By creating an account or using the service, you agree to these Terms. If you don't agree, please don't use CarSignal.
1. Who can use CarSignal
CarSignal is for U.S.-based independent auto repair shops and their employees. You must be at least 18 years old and have the authority to enter into this agreement on behalf of your business.
2. Your account
You're responsible for everything that happens under your account, including actions taken by your technicians and staff. Keep your credentials safe and notify us immediately at admin@trycarsignal.com if you suspect unauthorized use.
3. License
Subject to these Terms and your payment of applicable fees, CarSignal grants you a non-exclusive, non-transferable, revocable license to access and use the service for your shop's internal business operations.
4. Acceptable use
You agree not to:
- Resell, sublicense, or white-label CarSignal without written permission.
- Reverse engineer or attempt to extract source code from the service.
- Use the service to send unsolicited marketing (spam) — outreach must comply with TCPA, CAN-SPAM, and any other applicable laws.
- Upload content that violates intellectual property rights, contains malware, or is unlawful.
- Use AI-assisted output as the sole basis for diagnosis, repair, customer communication, quoting, invoicing, or parts ordering without qualified shop review.
5. Your data
Your shop's data belongs to you. CarSignal processes it on your behalf to provide the service, as described in our Privacy Policy. We do not sell your shop's operational data or share its customer, vehicle, repair, quote, invoice, or payment records with advertisers. Limited public website and demo-funnel data may be shared for advertising measurement when a visitor permits it, as described in the Privacy Policy.
6. AI features
CarSignal includes AI-assisted features for diagnostics, repair guidance, summaries, message drafting, quote descriptions, inspection support, and in-app assistance. AI output is generated automatically and may be incomplete, inaccurate, outdated, or inappropriate for a particular vehicle, customer, or repair situation. AI output is intended to assist qualified shop personnel, not replace professional judgment.
You are responsible for reviewing, verifying, editing, and approving any AI-generated content before relying on it, sending it to a customer, using it in an estimate or invoice, ordering parts, or performing repairs. CarSignal is not responsible for repair decisions, customer communications, parts orders, estimates, invoices, or other actions taken based on AI-assisted output.
7. Shop operations, repairs, estimates, invoices, and parts
CarSignal is workflow software for repair shops. It is not a licensed repair dealer, technician, legal advisor, tax advisor, accountant, parts supplier, or compliance service. Your shop is responsible for the work it performs and for complying with all laws and regulations that apply to its business, including laws relating to estimates, repair authorizations, invoices, disclosures, taxes, environmental fees, parts, labor, warranties, customer communications, and recordkeeping.
You are responsible for reviewing all customer-facing and internal records before using or sending them, including quotes, estimates, repair orders, inspections, diagnoses, invoices, payment requests, customer messages, vehicle information, VINs, license plates, mileage, labor rates, labor hours, taxes, fees, parts condition, parts pricing, and totals. CarSignal may help generate, calculate, organize, or display this information, but your shop remains responsible for its accuracy and legal sufficiency.
When using parts-related features, you are responsible for verifying part fitment, availability, supplier, quantity, condition, pricing, delivery, return eligibility, warranty terms, customer authorization, and whether a part is appropriate for the vehicle and repair. CarSignal is not responsible for supplier errors, fitment issues, delivery delays, pricing changes, order issues, or repair outcomes.
8. Third-party services
CarSignal may integrate with or rely on third-party services that you connect, authorize, or use through the service, including services for payments, accounting, messaging, email, parts, calendar, mapping, data, AI, hosting, storage, and other workflow functions. Your use of those services may be governed by their own terms and policies. We are not responsible for the availability, accuracy, security, pricing, actions, omissions, errors, delays, or outages of third-party services.

Approved documents. Any amount shown on a quote or invoice a customer approved stays exactly as approved.

9A. Payment Processing Agreement
This Payment Processing Agreement is entered into between CarSignal ("Platform") and the shop that accepts these Terms ("Merchant"). It forms part of these Terms and governs the Processing Services described below. Where this Payment Processing Agreement and the rest of these Terms conflict regarding payment processing, this Payment Processing Agreement controls.
Processing Services
In addition to its core services offering, Platform offers embedded payments processing services, which include credit card, debit card, ACH, and other payment processing services, as may be offered from time to time (collectively the "Processing Services"). Processing Services let Merchant accept payment from its customers on invoices, deposits, and payment links sent through CarSignal.
Processing Fees and Taxes
Related to the Processing Services, Platform will charge Merchant according to the fees listed below ("Processing Fees"). All Processing Fees payable under this agreement are exclusive of taxes. Processing Fees are separate from the CarSignal subscription described in Section 9.
| Processing Fees | Rate |
|---|---|
| Card payments online (Visa, Mastercard, Discover, American Express) | 2.7% + $0.30 per transaction |
| Card payments in person (tap on the shop phone) | 2.5% + $0.30 per transaction |
| International cards | +1.0% on top of the card rate |
| Bank transfer (ACH) | 0.8% per transaction, capped at $15.00 |
| Refunds | No fee; the original processing fee is not returned |
| Disputes (chargebacks) | $20 per dispute |
| Returned bank transfers | $20 per return |
| Bank account verification | $1.50 once per account |
| Deposits to your bank | Free, daily by ACH |
| Monthly, setup, or PCI fees | None |
Card transaction fees are charged on sale transactions only. In-person rates apply to card-present payments taken through a CarSignal-supported terminal or tap-to-phone device; all other card payments are charged at the online rate. The same schedule is shown on the Payment Processing Agreement page presented during CarSignal Payments setup.
If Merchant has an alternative pricing agreement with Platform, that agreement sets the official pricing and takes precedence over the table above.
Fair use policy
Platform may increase the card Processing Fees if Merchant's (a) American Express credit card payment dollar volume exceeds twenty percent (20%); (b) corporate credit card payment volume exceeds ten percent (10%) of total monthly credit card payments; or (c) credit card payments for transaction amounts greater than one thousand dollars ($1,000.00) exceed three percent (3%) of total monthly credit card payments. Such increases become effective only after Platform has provided Merchant written notice setting forth the changes.
Processing Terms and Conditions
By using the Processing Services, Merchant agrees to the Processing Terms and Conditions available at https://legal.rainforestpay.com/processingterms, which may be amended at any time on notice. Acceptance of those Processing Terms and Conditions is a requirement of Platform's upstream banking partners and the card brands.
Data sharing
Merchant authorizes Platform to share Merchant's business, onboarding, transaction, and payment method data with Rainforest Pay, Inc. and its sponsor banks and payment networks as needed to provide the Processing Services, including merchant onboarding, underwriting, risk monitoring, dispute handling, and tax reporting. Merchant also authorizes that data to be exported to Platform or Platform's designee at any time. The Processing Terms and Conditions linked below may be amended by Rainforest at any time on notice.
Term
The term of this Payment Processing Agreement begins when Merchant accepts these Terms or first uses the Processing Services, whichever is earlier, and continues until terminated by either party. Termination of a Merchant's CarSignal account terminates this Payment Processing Agreement, subject to any Processing Fees, chargebacks, returns, or disputes that accrue afterward.
10. Communications from CarSignal to you
By creating an account, you consent to receive transactional communications from CarSignal at the email address on file — including billing notices, security alerts, important product updates, and outage notices. You can't opt out of transactional communications while you have an active account; closing your account stops them.
We may also send occasional product news, tips, and announcements. You can opt out of these marketing communications at any time by clicking unsubscribe in the email or by emailing admin@trycarsignal.com.
11. Messaging to your customers (SMS & email)
CarSignal lets you send SMS and email messages to your customers, including booking follow-up, appointment reminders, estimate approval links, repair status updates, invoice links, vehicle-ready updates, and responses to customer inquiries. When you use these features:
- You are the sender. You are responsible for complying with the Telephone Consumer Protection Act (TCPA), the CAN-SPAM Act, the FCC's 10DLC requirements, and any state laws (e.g. CA AB 660) applicable to your messages.
- You confirm that every customer you message has given you prior express consent (or, where required, prior express written consent) to receive SMS and/or email from your shop at the number/address provided.
- You will honor opt-out requests promptly. Customers replying STOP, UNSUBSCRIBE, or similar must be removed from further messaging within the time required by law. Customers may opt back in by replying START or by submitting a new consent through a booking or intake form.
- Customers can get help by replying HELP to an SMS message or by contacting the shop directly. CarSignal can be reached at admin@trycarsignal.com.
- You will not use the service to send unsolicited marketing, content unrelated to your shop's services, or anything unlawful, harassing, or deceptive.
- Message frequency varies based on the customer's repair activity, appointment status, estimate or invoice activity, and support conversation.
- Carriers may charge your customers for SMS messages. Standard message and data rates apply.
- Carriers are not liable for delayed or undelivered messages.
- For details about how CarSignal handles personal information and SMS consent data, see our Privacy Policy.
We may suspend messaging features if we receive complaints or carrier feedback indicating non-compliance. You indemnify CarSignal for any claim arising from your messaging to customers.
12. Termination
You can stop using CarSignal at any time by contacting us. We may suspend or terminate accounts that violate these Terms, fail to pay amounts owed, or pose a security risk. On termination, your access ends; data is handled per our Privacy Policy.

To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service, AI output, integrations, calculations, messages, estimates, invoices, parts information, order information, or other content will be accurate, complete, uninterrupted, secure, timely, or error-free.
14. Limitation of liability
To the maximum extent permitted by law, CarSignal's aggregate liability arising out of or relating to these Terms or the service is limited to the amount you paid in the 12 months preceding the claim. We are not liable for indirect, incidental, consequential, or punitive damages, including lost profits or data.
To the maximum extent permitted by law, CarSignal is not liable for claims arising from repair work, diagnosis, inspections, estimates, invoices, taxes, fees, parts selection, parts ordering, supplier issues, customer communications, messaging compliance, third-party services, or your reliance on AI-assisted output or other content generated through the service.
15. Indemnification
You agree to indemnify CarSignal against claims arising from your use of the service, including violations of these Terms, infringement of third-party rights, unlawful messaging to your customers, repair work, customer disputes, estimates, invoices, taxes, fees, parts orders, third-party integrations, regulatory violations, or your use of AI-assisted output.
16. Governing law
These Terms are governed by the laws of the State of California, without regard to conflicts-of-law principles. Disputes will be resolved in the state or federal courts located in California.
17. Changes
We'll post changes to these Terms here and update the "Last updated" date. Material changes will be announced to shop admins by email. Continued use after the effective date constitutes acceptance.
