How to Use Bulk Invoice Payment QR Codes
An invoice gets paid faster when paying takes one scan instead of retyping a link or reference. Generating one code per invoice from a single CSV keeps every invoice consistent, and because each code carries its own invoice number, payments are far less likely to land against the wrong invoice.
Match each code to its invoice before sending
The costly mistake is a code that opens the wrong payment page. After generating a batch, spot-check several codes by scanning them and confirming the invoice number and amount on the payment page match the invoice. Never reuse a payment link across invoices.
Print and test before the batch goes out
Print a sample at the real size and scan it in normal office lighting, then confirm the scanned text matches the invoice. Keep the quiet zone clear, use dark modules on a light background, and keep the code away from folds and staple zones.
