Reset the invoice identifier {{{ID}}} tag each month


I have created this Invoice group with this invoice numbering.

Now how, can i make the {{{id}}} reset back to 1 each new month.

In the month november i created 3 invoices.

  • EUR/2021/11/1
  • EUR/2021/11/2
  • EUR/2021/11/3

The next month in december, the ID must start with 1 again automatically. And not with 4, otherwise where are invoice 1, 2, 3 of the month December and that’s illegal in my country.

I don’t know if this is possible already or to create this with a cron job in some way?

Already thank you and keep up the amazing work.
best regards,

See Martin’s previous response.

Would really love to see that feature!!

My Invoices are named like this:

R19.03.18|1 (unique ID is “1”)

The next day I want the first Invoice look like this:
R19.03.19|1 (unique ID is “2”)

Maybe this would make sence:
{{{did}}} (daily ID, reset every day)
{{{mid}}} (monthly ID, reset every month)
{{{yid}}} (yearly ID, reset every year)

So I would rename my Invoice names to:

would make sense.
otherwise Invoices have very ugly names over time…

Thats true, I would not change/modify {{{id}}}, but instead of doing this I would create the three ID-helpers I mentioned above.

I’m going to close the topic
I suggest you start working on his solution.
