Repeat client billing · manual review
Service-date rate change checker
A recurring client’s invoice can contain work before and after an agreed rate change. Apply the rate to each service date instead of pricing every job at the rate shown on invoice day.

Fictional worked example · not a customer case
Check one specific result
In this fictional month, two hours on 14 October use AUD50/hour and 90 minutes on 15 October use AUD60/hour. The reviewed amount is AUD190.00. Pricing both at the new rate would produce AUD210.00; the dates explain the difference.
Method and boundaries
The entered change date belongs to the new rate; earlier dates use the previous rate. Each referenced job is calculated independently and rounded to cents. Only one change boundary is supported. Work spanning that boundary must first be split into separate approved records.
A date on a spreadsheet is not evidence that a client accepted a rate. Do not retrospectively edit an issued invoice from this result. Missing approvals, multiple rate changes or customer-specific exceptions need a separate source-record 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.
