Invoice numbers and due dates

How invoice numbers are given, why one can be missing, and how the due date and Overdue are set.

For tutors. Updated October 2026.

Where to find it

Open an invoice. Its number is at the top of the sheet: INV, the year, then a number that counts up, such as INV-2026-0003.
Read the two dates under it: the day it was issued, and the day it's due.
Optional: When you make an invoice, change its Due date if the family needs more or less time.
It starts 7 days after the Invoice date and can't be before it.
Watch the status. While money is left to pay after the due day, the invoice reads Overdue and its due date turns red.

The Al Mansouri family's issued invoices on 30 September. You gave this family 14 days to pay each one:

INV-2026-0002 has AED 290 left to pay. If it isn't paid by the end of 1 October, it reads Overdue from 2 October, and the line under Unpaid on your dashboard reads AED 290 overdue.

The same number, date and due date on their invoice and its PDF.
Once it's overdue, their portal marks the invoice Overdue, and their balance shows how much is overdue.

Numbers count up across all your invoices, families and students together, and start again at 0001 each year.
An invoice is numbered when you make it, drafts included, and keeps its number for good, even once cancelled.
A number is never used twice. If you delete a cancelled invoice, its number stays taken, so your numbering has a gap.
Numbers follow the order you make invoices, not their dates. An invoice you date in the past takes the next number of its date's year: dated in December 2025, it gets an INV-2025 number.
You can't choose or change a number.
Once an invoice is saved, its due date can't be changed. To change it, cancel the invoice and invoice the sessions again.
A draft gets its due date when you save it: 7 days after that day, whatever due date it had as a draft.
With Auto-send on, an automatic invoice is due 7 days after it's issued. Without it, the invoice is a draft, due 7 days after you save it.
Overdue starts the day after the due date, in your timezone. An invoice with nothing left to pay is never overdue.

Look under Cancelled: a cancelled invoice keeps its number. If it isn't there, it was deleted, and its number is never used again.

It was made later and dated in the past. Numbers follow the order invoices are made.
