Test cash application on one of your own remittances
Before you choose any tool, see what matching does with a real remittance and your real open invoices. Upload one remittance as a spreadsheet (CSV or Excel) and your open-invoice export. Remit Match matches every line and flags short pays, overpays, duplicates and lines it can't find. Your files are read in memory and not kept; only your email address is kept, for 7 days.
