The same job
Turn a quote into an invoice without retyping it.
Price the work as a quote. When they say yes, convert it — same client, same line items, same GST. Mark it sent or paid. When the money lands, issue a receipt from that record. One Android app, three documents.
Export each stage as an A4 PDF from the share sheet. Three documents are free so you can try the loop. Unlimited quotes, invoices, and receipts are $20 NZD once. No subscription.
