Repeat client billing · manual review
Invoice business-day count checker
An agreement expressed in business days is not the same as adding calendar days. Count weekdays after your chosen start event and explicitly exclude the dates relevant to that customer agreement.

Review inputs and results
The prefilled values are fictional examples. Replace them with verified data, without customer names, contact or payment details. Inputs stay in this page; review again after changing them. No GST is automatically added.
Select Review calculation to inspect the entered values.
Fictional worked example · not a customer case
Check one specific result
The fictional example starts Friday 30 October 2026 and counts three later weekdays, excluding 3 November. It reaches Thursday 5 November. Business Victoria lists Melbourne Cup on 3 November 2026, with local exceptions; use the calendar that actually applies to your agreement.
Method and boundaries
The start date is day zero and never counted. Saturdays, Sundays and your entered exclusion dates are skipped. The result table lists every examined date so the boundary can be checked. Duplicate excluded dates are rejected to make the input list explicit.
No national or state holiday calendar is loaded automatically. This does not determine a legal deadline, debt status, interest or contractual definition of business day. Zero-day terms, weekend trading calendars and different counting rules need their own review.
From a reviewed number to an invoice
- Confirm the actual customer, scope, period and approved charging basis.
- Match each row to source job records; fictional examples are not customer data.
- Download a manual review record if useful; it does not replace original invoices or accounting records.
- Manually enter appropriate AUD line items in the tool, check the preview, then export the PDF or image yourself.

Questions before invoicing
Does this result create or change an invoice?
No. This page calculates a manual review only. Nothing is sent to an account, saved to an invoice draft or automatically copied into ABN Invoice. Review the agreement and enter an approved customer document yourself.
