Pressure washing crews complete 5–15 jobs per day with before/after photo evidence expected by most commercial clients as proof of service. Paper route sheets that don't capture service areas, chemical types, and completion photos mean contract clients can dispute whether the work was done — and EPA stormwater compliance records that live on paper sheets rather than digital logs create regulatory exposure on commercial and industrial accounts.
Objective third-party statistics and research benchmarks relative to quoting & invoicing and pressure washing workflows.
A sales estimator quotes a commercial parking lot cleaning and fleet washing contract verbally after a walkthrough. The proposal is written up from memory two days later. The client signs the contract and then disputes scope on the first invoice.
Verbal or delayed proposals on commercial cleaning contracts create scope disputes on 15–20% of first invoices — particularly around square footage, chemical type, and number of fleet vehicles that were included in the walkthrough discussion.

Late invoicing extends DSO by 15–30 days. Inconsistent quoting costs 5–10% in margin leakage.
These tools are great at what they do — but they don't eliminate the quoting & invoicing gap. That's what we build.
We study exactly where quoting & invoicing happens in your pressure washing operation — the forms, the handoffs, the re-entry points.
Not a demo. Not a slide deck. A real, functional prototype that eliminates the pain point and works with your existing tools.
You test the prototype on a real job. If it doesn't eliminate the quoting & invoicing problem, you don't pay.
