Hi,

There is no sequence record for invoice is present in Odoo V14.Some custom modules are available for the same.

Eg:

The invoice sequence is missing on the menu Technical/Sequences. When you create the first invoice, odoo shows an editable default sequence "INV/YEAR/0001", so you can custom the format and the next invoices you make will keep your format. It worked to me.

So, in Odoo 14 Community I just found that a "-SQ" was being added to the end of my Invoices.  That was not desired or intended.

After looking for an Invoice Sequencing control and not finding the way I have found to set in Sales Order..  I read the above posts but did not see a solution.

I tried then the following and found it solved the issue.
Arguably a new issue but related:

1:  Create a Test Invoice (test customer)

2:  Confirm the invoice

​the "-SQ" was added again.
3:  Revert the Invoice to Draft

4: Edit the Invoice number, removing the "-SQ"

5:  Confirm the invoice again

6:  Create a new (2nd) Draft Invoice

7:  Confirm the 2nd Draft Invoice
​I found that the "-SQ" was no longer in the invoice number and it was based upon date (INV/YEAR/MO/SERIES)

This can likely still be controlled somewhere.  For instance, putting a Day code in there before the series, for example.

Anyway, my problem went away by "revert to draft", "edit", then "confirm" on a test invoice, and testing on a second test invoice as stated above.

The invoice sequence from version 14 onwards is dynamic.

You can modify it directly in a draft invoice. Odoo detects directly the dynamic fields "Year" "Month".

I try to use re sequence and put E001-0001 and the system set E020-0001, why??
