Invoice Chief is the full invoicing application behind this sign-in screen. You create an estimate on site, collect the customer's signature, turn the approved estimate into an invoice, send it by email, SMS or WhatsApp, and track what has been paid and what is still outstanding — all from your phone.
It keeps your customers, saved line items, sequential invoice numbers, payments and job history in one place, so the work does not stop when the invoice is sent.
Learn more about the app on the Invoice Chief invoicing software page, or read how it works for contractors and for freelancers. Invoice Chief also offers a secondary one-off tool, the invoice generator, and a library of invoice templates.
