Vetting fleet wash vendors without guesswork
A missed morning wash on a last-mile fleet is not a cosmetic problem, it is a dispatch problem. Awarding that work on a star average is a bet. This guide walks through building a shortlist, comparing it on the same fields, and turning it into an RFQ.

Step one
Build one shortlist, in one place
Open the market page for the yard's city, then use WashAttest compare to hold up to four operators side by side. Comparing bidders on one page, instead of four open tabs with four different formats, is what makes the next step possible.
Step two
Compare the fields that actually predict performance
On-time rate and sample size
The rate inside the agreed service window, plus how many visits it is based on. A rate with no sample size is not evidence.
Rework rate
How often a unit had to be redone. This is a better signal of crew quality than a star average.
Insurance and expiry dates
General liability and workers’ compensation, with the date each was last checked, not just a checkbox that says insured.
Water reclamation
Required at many commercial and fleet sites. Confirm the method, not just that the vendor says they comply.
Open disputes
Not every vendor with zero disputes is clean; some platforms let vendors bury complaints. A visible, dated dispute record is the stronger signal.
Units per night
Confirms the vendor’s crew size and equipment actually match your fleet’s volume, not just a willingness to bid.
The full field list, with benchmarks for a trailing twelve months, is in the 2026 fleet wash benchmark.
Step three
Turn the shortlist into one RFQ
Export the comparison as a request-for-quote packet and send identical unit counts and cadence to every bidder. The procurement toolkit walks through the sequence, and the compliance checklist lists the documents to collect before you sign.
Step four
Keep measuring after you award the contract
A vendor that looked strong at bid time can slip. The operations standard defines the minimum record a vendor should keep for every unit, every visit, so a slipping on-time rate shows up in the data before it shows up as a missed route.
Common questions
FAQ
How many vendors should I compare before awarding a fleet contract?
WashAttest lets you hold up to four operators side by side. Three to four bidders is usually enough to see a meaningful spread without slowing down procurement.
What is the single most useful field to compare across bidders?
On-time rate inside the agreed service window, paired with its sample size. A high average built on five visits is weaker evidence than a slightly lower average built on five hundred.
Should I still get an RFQ if a vendor looks attested?
Yes. An attestation and the RFQ packet are planning tools. Confirm current certificates and site-specific terms directly with the vendor before signing a service agreement.
