The fillable PDF receipt is for issuing a receipt on the spot from a phone: the client pays, you open the template in the Files app, type five fields, and send it by text or email before you leave. It has the payer, the date and method, what the payment was for with the invoice number, the amount received and the balance remaining, plus a signature line for cash.
Free, one page, US Letter. No email, no sign-up. It works in Preview, Adobe Reader, Chrome and the iPhone Files app; nothing to install.
Same layout in other formats: Word (.docx) · Excel / Sheets (.xlsx)
The layout: header, bill-to block, line table, totals, terms. Same in every format; the format changes how you fill it.
