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. |
Build a job record a reviewer can follow
Start with one completed example, not a blank legal form. Give the customer or buyer an identifier, then record the vehicle, work site, service, condition limit, price method, and proposed date. Keep the same identifiers on the quote and invoice.
A named work site matters for a mobile job. Ask who can approve access, parking, water, power, and the runoff plan. If the site cannot support the process safely, the service description cannot make the job possible. Stop and choose another site or method.
Record the condition found before work. A photo may help when the owner permits it. Written notes can describe heavy soil, damage, or a surface that needs a different method. Store any photo with its permission record and job identifier.
The reviewer needs the business facts in plain language. Mark an unknown answer as pending and name who will resolve it. Do not turn a missing fact into a legal assumption. A customer contact can confirm site access; a lawyer must review the legal effect of contract terms.
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.
Worked example: one change in scope
This example is hypothetical. A customer accepts a $180 maintenance wash for one vehicle at a stated address. The written scope covers exterior panels, outside glass, and wheel faces. Heavy deposits and paint correction are excluded. The customer approves a Tuesday arrival window.
At inspection, the operator finds a bonded deposit that the wash will not remove safely. The operator records its location and stops that part of the work. The accepted $180 scope still covers the wash. A stronger chemical or abrasive step needs a new assessment.
The operator offers a separate inspection and quote for the deposit. The record gives the proposed added task, price, changed time, and the person who can approve it. No added work starts from a spoken assumption or a silent line on the final invoice.
If the customer declines, complete only the accepted wash when safe. Note the unchanged scope and the declined addition on the job ticket. If the deposit makes the wash unsafe, record the stop. Ask the lawyer to review any payment or cancellation term before relying on it.
The example passes when the original quote, change request, answer, job notes, and invoice tell one consistent story. A later reviewer can see which work was approved and which work did not happen.
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.
Check recurring work one cycle at a time
A fleet schedule adds changing vehicles and staff. Write how the buyer will identify each vehicle before a visit. Record who can add or remove a unit and how the unit list reaches the operator. A price per vehicle cannot be checked against an unnamed fleet.
Set a service-level record for each visit. The record can name the selected scope, condition limit, site contact, start and finish, and any exception. The invoice should then reconcile to completed units, not to an assumed full schedule.
Suppose a planned visit has 10 units but only eight are available. Those counts are hypothetical. The service record shows eight completed and two missed with the reason. The legal reviewer decides whether a minimum charge or reschedule term belongs in the agreement. The work record must show eight completions.
Keep staff authority clear. A driver may hand over keys but lack authority to order extra work. Write the buyer's approver in the review packet. If an unexpected condition appears, request approval from that person through the agreed path.
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.
Close the record after the job
Match the accepted scope to the completed service line by line. Record an exception before sending the invoice. The invoice amount must follow the approved price method and approved changes. Save payment status separately from the work record.
Keep each dated version available. If a customer asks what changed, the old and new records should show the answer. A revised agreement needs the same local legal review as the terms it changes.
Use the checklist to gather facts before the lawyer's review. Put open questions in a separate section with a named decision-maker. That gives the lawyer a complete business record without presenting the checklist as legal wording.
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.
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.
