How it works
Every invoice gets the next number in your business's sequence when it's created: INV-00001, INV-00002, INV-00003 and so on. The five digits keep them in order wherever they're sorted.
Navigate to: Sidebar โ Invoice
The new invoice form shows Auto-generated where the number goes, and the number appears once you save.

Which invoices share the sequence
All of them: invoices you create, invoices made from a booking, and invoices created when a customer accepts a quote. Quotes have their own sequence, starting at Q-0001.
Good to know
- Drafts get a number too, as soon as they're saved.
- Numbers are never reused. Deleting an invoice leaves a gap in the sequence.
- There's no setting to change the prefix, start from a different number, or type your own number.
Tip: Moving from another system? Tell your accountant the date you started invoicing in Wemu, so they know where the old sequence ends and the new one begins.
