Photo-backed completion reports, your SH mix logged properly, and somewhere to record where the wash water went. $59, once.
Not a generic "service call" form with a notes box. The fields are the ones that matter on a wash, and the report at the end is the one a property manager will accept without a phone call.
Open the job, shoot your before photos per surface, and note what condition it was in when you got there. That's the part that saves you when someone says you etched their concrete.
Log each area with the mix you used, the strength, and how much. Downstream or direct, surface cleaner or wand — it's a couple of taps, not a form.
Where the wash water went, and whether you had permission. Storm drain rules vary by town and Sterling doesn't pretend to know yours — it just makes sure you wrote it down.
After photos, customer signs on the phone, completion report generated, invoice sent with a payment link. Before you've coiled the hose.
Half the commercial work in this trade is behind a building or in a lot with one bar. Do the entire job offline — photos and all — and it syncs itself when you're back in range.
Surface and area treated · product and strength · quantity · method · dwell and rinse · before and after photos per surface · pre-existing condition · wash-water destination and permission · conditions on the day · customer signature · your own numbered record.
It won't tell you what your municipality allows, and it won't say you're compliant with anything. It links you to the EPA and your local sewer authority and keeps your record straight. That's the deal.
There's a button inside every work layer that sends me a message. I read all of them myself. When a fix ships because someone told me, it goes in the changelog with a thank-you — that's how the next fifty people get a better version of this.
