Invoice number with with prefix and postfix

1

Is possible to update Invoice number with with prefix and postfix column?

eg : MBS/1011/2020 like that ?

No is the short answer.
It is possible to position custom fields near the invoice number sent invoices with custom themes so it looks a bit like that but the underlying sequence number will not be effected by the prefixes & post fix, nor is it possible to restart the sequence number.

The closest you can do is allocate banks of numbers to each period eg

2019000000001
2019000000002
2019000000003

2020000000001
2020000000002
2020000000003

2021000000001
2021000000002
2021000000003

It is worth mentioning that you can manually enter any reference number you want on any transaction. But you would need to keep track of sequences externally. See Use reference numbers | Manager.

You can use a custom theme combined with custom fields.
