A buyer will ask for proof, not a star average
Facilities and fleet buyers are increasingly comparing vendors on documented compliance and operating history before they ever look at reviews. If you run a mobile detailing, commercial pressure washing, or fleet washing business, this is the record worth building now, before a procurement team asks for it.

Why it matters
Recurring contracts go to the vendor who can prove it
A one-off driveway detail can be won on price and availability. A recurring commercial pressure washing contract or a fleet washing program is awarded to the vendor who can answer procurement's questions without delay: current insurance, a real on-time rate, and a documented plan for wash water. Building that record is what the WashAttest Standard describes.
What to have ready
The four records a buyer will ask about
- 01Compliance file. Keep current certificates for general liability and workers' compensation, your business license, and stormwater or NPDES status if your work touches a storm drain. Note the expiry date on each one, and renew before it lapses, not after.
- 02Operational scorecard. Start logging on-time rate, rework rate, and response time now. The scorecard is built from a trailing twelve months, so a business that starts tracking today has a real record by the time a bid comes up.
- 03Proof of work. Before-and-after photos, a wash log with date and unit, and a per-unit report that reconciles to the invoice. This is the evidence that turns a claim into a record.
- 04Dispute handling. When a customer disputes a job, document the claim, your response, and the resolution. A visible, resolved dispute reads better to a procurement team than a vendor with no history at all.
Where to start
Read the standard, then build the file
The full checklist for each record, including what counts as complete, partial, or expired, is published in the WashAttest Standard. If you take commercial pressure washing work, the pressure washing compliance checklist breaks the documents down by job type.
Common questions
FAQ
Does attestation cost money?
WashAttest publishes a standard and a comparison tool; it does not sell a pay-to-rank badge. An attestation is a documented check against the published standard, not a listing fee.
What if my business is new and has no twelve-month history yet?
Start the compliance file and proof-of-work habits now. The operational scorecard is built from a trailing twelve months, so the sooner you start logging visits, the sooner you have a real record to show.
Do I need to hide a past dispute to qualify?
No. The dispute record is supposed to show the claim, your response, the evidence, and the outcome. A resolved dispute with a documented response is a stronger record than no history at all.
