Set a supplier bill due date

Use this to translate invoice payment terms into Due Date. Have the supplier invoice, Bills access and a valid Bill Date. The due date is optional on the single-bill form but should be checked against the invoice. A due date is not an instruction to pay.

1. Open Bills → Enter Bill and enter the invoice's Bill Date. If the invoice states a specific date, enter it directly in Due Date.
2. If the invoice instead specifies a supported term, select its checkbox beside Due Date: 7 days, 14 days, 21 days, 30 days, or 30 days EOM. Only one term is active at a time. The first four add calendar days to Bill Date, including across month and year boundaries. 30 days EOM means 30 calendar days after the last day of the invoice month, not 30 days after the invoice date.
3. Inspect the resulting Due Date against the invoice. Changing Bill Date recalculates an active term. Selecting that same term again switches it off and restores the previous due date. Manually editing Due Date switches off the selected term. Save your draft or push only after the date is right.

Worked examples: For an invoice dated 15-09-2026, 7 days gives 22-09-2026; 14 days gives 29-09-2026; 21 days gives 06-10-2026; 30 days gives 15-10-2026. 30 days EOM starts from 30-09-2026 and gives 30-10-2026. For an invoice dated 31-01-2026, 30 days EOM starts from 31-01-2026 and gives 02-03-2026; it does not mean the last day of February. These dates are DD-MM-YYYY, although the browser's date-picker display may vary.

Other entry points: Multi-page groups have their own bill/due dates and term choices; verify each segment separately. In Bill History, draft editing also supports date terms. Bulk Edit accepts a specific due date for all selected eligible bills; a blank bulk due date keeps their existing dates. Rules can suggest a due-date term, but a supplier's actual invoice takes precedence in your review.
