In India the accounting period starts from for example 1/4/2016 to 31/3/2017, the next period starts from 1/4/2017 to 31/3/2018 and so on.
Every year we renumber the invoices.
How do I do this in Manager? Please help
This has nothing to do with your accounting period. If you want invoice numbers with new fiscal-year indications, add a prefix such as 2018XXXXXXXX. Manager adds one to the highest existing number. After you have redone the first one, it will auto-number for the rest of the year.
Remember, though, to include enough digits in XXXXXXX to accommodate the full year. If you were to start out with 2018XXX and reached 2018999, the next invoice would not be 20181000, but 2019000. The numbers are just numbers, so the prefix is not treated as a prefix.
Our accounting period starts from April to March, and we start the invoice numbers from every year.
As I said, this has nothing to do with when your accounting period is. No matter what your accounting period, Manager will find the highest existing number and add 1.
