Signed on site.
Billed at the office.

Once the customer has signed, the order flips automatically from in progress to completed. In the same moment, the order is flagged invoice-ready — you or the office can create the invoice with one click. All data is already there: order number, customer, address, hours, materials.

Yes. In the sign-off form you can record defects with photo, description and deadline. They land in the PDF protocol and the order stays open until they're fixed. Remaining work follows the same pattern — partial sign-off, the rest stays open.

Yes. On site, dead zones are the rule, not the exception. The app stores the sign-off locally with timestamp. Once the signal's back, everything syncs. The customer doesn't notice, neither do you.

Yes. Right after sign-off you can email the PDF to the customer or show it on the phone. The protocol contains: order number, address, defects list, both signatures, date and time.

Works. You mark the positions that are signed off and the ones that stay open. The order is flagged partially-accepted, the invoice can be created proportionally. The rest stays open until defects are fixed and signed off again.

Directly. The status flip to completed is the trigger: from the recorded hours, materials and order data, the invoice almost writes itself. You just check it, then tap send — as an e-invoice in ZUGFeRD format if your customer needs it.
