Real screenshots, not mockups. This is the actual product, the day this page was made.
Who owes you, what's coming up, what the month looks like — and your trade's work layers first in the menu, because they're the point.

Phone, email, history, what they owe. Tap the phone number and your phone dials it.

Send with a payment link, or print a QR code they can pay standing in the driveway. Late ones chase themselves.

Estimates become jobs, jobs become invoices. Nothing retyped, nothing lost between steps.

Your crew works on their phones all day — jobs, hours, expenses. By the evening it's here, filed, exactly once.

Create a seat, hand your tech a code, and their phone is part of the business. Revoke it just as fast when someone moves on.

Pick a tier on the pricing page. One payment — there is no step where a subscription starts.
BackOffice runs in any browser at app.sterlingesolutions.com — sign in with the email you bought with. Nothing to install.
Name, logo, tax rate, invoice preferences. Five minutes, once.
Add a client, raise an invoice, send it with a payment link. That's the whole loop — everything else builds on it.
Crew Registry → Add OfficeKit → type the code into the phone. The field app tour below shows what the phone side looks like.
