How to Convert an Estimate to an Invoice on iPhone
A short, focused walkthrough for converting any QuickBill estimate into an invoice in one tap, without retyping any line items.
Key takeaway
Open the estimate, tap Convert to Invoice, edit if needed, then Share. The estimate stays in your records and the new invoice gets a fresh sequential number.
Estimates and invoices share most of the same data — client, line items, taxes, totals, notes. Re-entering all of that just to bill is a workflow tax. Here is the QuickBill conversion flow.
- Open the Estimates tab in QuickBill.
- Tap the estimate you want to bill.
- Tap Convert to Invoice.
- QuickBill creates a new draft invoice with all line items, taxes, discounts, notes, and the client copied across.
- Edit anything you need to (e.g. split into two invoices, change due date).
- Tap Share to send the PDF.
What gets copied
- Client information.
- All line items (description, quantity, rate, amount).
- Taxes and discounts.
- Custom notes and payment instructions.
- Currency.
What's new on the invoice
- A fresh sequential invoice number.
- A new issue date (today by default).
- A new due date based on your default payment terms.
