Hi all

I'm using Odoo 18 Online (SaaS) and I've set a custom invoice sequence in the Customer Invoices journal like this:

So invoice numbers look like: INV-4001/25, INV-4002/25, etc.

The problem:

Every time I create a new invoice, the suffix doesn’t stay as /25. Instead, it self-increments on its own like this:

I manually entered /25 as the suffix — I don't want it to increase like part of the number.

A way to lock the suffix to stay as /25
OR a proper method to dynamically use the year (e.g., auto-update to /2025, /2026etc.) if that's even supported on Online/SaaS

Appreciate any insights, thanks!

I fixed this issue by creating a custom sequence and attaching it using server automation (Automated Action).

for record in records:

if not record.name or record.name == '/':

record['name'] = env['ir.sequence'].next_by_code('custom.invoice.sequence')
