The field app, photographed at phone size. Works with no signal — a basement, a crawlspace, a metal roof — and syncs when you're back in the world.
Today's jobs, quick capture, and the sync status — built for a phone held in one hand with gloves on the other.

Job details, hours, photos, signatures — saved on the phone itself, whether or not there's signal.

Estimates, expenses, mileage, invoices — the More menu carries the full toolset, gated by what the boss allows each seat.

Pack today's work, hit Send, and it lands in BackOffice — filed once, duplicates impossible, conflicts resolved in the office's favor.

Work layers made for your trade — chemical logs, inspection certificates, service records. $59 once, every seat, forever.

On the phone: field.sterlingesolutions.com. iPhone uses Safari, Android uses Chrome.
iPhone: Share → Add to Home Screen. Android: tap Install when Chrome offers. It gets an icon and opens full-screen like any app.
Same email as your purchase. The free Service Log layer is already there.
The one from BackOffice's Crew Registry. From that moment the phone is part of the business.
Do the day's work — signal or not. At day's end: Daily Send → Pack → Send. The office has it by dinner.
