A detailing agreement starts with a clear job record. Write the customer, vehicle or fleet, service, work site, schedule, price, and approval path. Then give the record to a lawyer licensed where the work occurs for the legal terms.
Download the service agreement review checklist. It prepares the business facts for review. It does not supply legal wording or replace local legal advice.
Separate the two jobs
A customer agreement covers a stated service for a named customer. A fleet or commercial agreement can add a service schedule, several vehicles, site rules, reporting, and a buyer approval process. Do not use one short customer record as the whole agreement for recurring work.
Start with the work you can perform and describe it in plain words. A legal reviewer can then identify terms that depend on your state, city, customer type, insurance, tax treatment, or property rules.
| Agreement type | Facts to prepare | Review focus |
|---|---|---|
| One customer job | Vehicle, condition, selected service, price, date, and approval record. | Scope, changes, payment, cancellation, and local consumer rules. |
| Recurring fleet or site work | Vehicles, service level, location, schedule, site contact, inspection record, and invoice cycle. | Authority to approve work, site access, insurance requests, reporting, and service changes. |
Write the scope so it can be checked
The scope passes when another person can compare the completed job with the approved work. Name each service, the vehicle or vehicle group, the work area, the condition limit, and the service location. Record work that needs another inspection or price as a separate change.
- Included work: hand wash exterior panels, dry, outside glass, and wheel faces.
- Vehicle or fleet reference: year, make, model, plate, stock number, or unit number.
- Condition limit: light road film only; heavy soil, pet hair, odor, or paint correction needs a new review.
- Site fact: customer supplies access, parking instructions, and the authorized contact.
The Federal Trade Commission says advertising claims must be truthful, supported, and not deceptive. Use the same clear service description in your agreement, quote, menu, and invoice. Do not promise a result that the approved process cannot support.
Set the price and approval record
List the price structure before a lawyer reviews the payment terms. A one-time job can use a fixed price for the stated scope. Recurring work can use a per-vehicle price, a scheduled minimum, or another stated method. Record what changes the price and who can approve it.
| Line item | What to record |
|---|---|
| Price | Fixed price, unit price, minimum, or other stated calculation. |
| Schedule | Service date, recurring interval, arrival window, and rescheduling contact. |
| Change | Added work, revised price, revised time, approver, and approval date. |
| Payment record | Invoice cycle, due date, payment method, and balance record. |
Keep taxes, deposits, cancellation charges, late fees, limits of liability, damage terms, waivers, and dispute terms for local legal review. Their effect can vary by jurisdiction and customer type. Do not copy them from another detailer or a general template.
Keep one record per agreement
The Internal Revenue Service says a recordkeeping system must clearly show income and expenses. It lists invoices among the documents that support business records. Keep the accepted agreement, quote, change approvals, completed invoice, payment record, and job photos in the same job folder.
Use a version date on each revised agreement. Keep the prior version with the change record. The current version should identify the customer, site, service period, and approver.
Prepare the review packet
Give the reviewer the checklist, your service menu, one completed hypothetical job record, and any customer-required insurance or site documents. Ask which local rules or terms must be added before you send the agreement.
Use a lawyer licensed in the relevant jurisdiction for legal wording and local requirements. Use a tax professional for tax treatment. Use your insurer or broker for coverage requirements that a customer requests.
Set the job scope first with the quote template. Use the invoice template after the work. The first paid detail guide covers the job sequence.
