# Number Settings
Number Settings define auto-numbering for every transaction type: whether IDs generate automatically, prefix and suffix, reset rules, and starting numbers. Configure separate series per sale type, purchase type, or payment mode when those options are enabled in Transaction Preference.
Overview & Form View
Go to Settings → Number Settings from the left menu.
The screen shows one or more grids grouped by module (Sales, Purchase, Payment/Receipt Voucher, Expense, Inventory, Payroll, HRMS, Production, Project, Service, CRM). Each row is a transaction type (or pay mode / field where applicable).

FAQ
Why do I see extra rows for payment modes?
Enable Payment voucher bill number per payment mode? (or receipt/expense equivalents) on Transaction Preference first.
Why did my sale invoice get a number in Draft?
Check Select Transactions in which bill number auto generate on draft on Transaction Preference.
Number Settings here vs the subsection in Transaction Preference?
Transaction Preference toggles how numbering behaves (multiple types, pay modes, draft auto-generate). This screen sets the series (prefix, suffix, counter) for each row.
What happens when I reset the counter?
The next document uses the starting number you enter — existing documents are unchanged. Plan counter resets at period boundaries carefully.
Can two types share the same prefix?
Technically yes, but use distinct prefixes per type to avoid duplicate numbers and confusion on printed documents.
Why is a transaction type missing from the list?
Enable the related toggle on Transaction Preference first — e.g. payment-mode series rows appear only after per-mode numbering is enabled.
Does changing prefix affect old documents?
No. Only new documents pick up the updated series. Historical bill numbers remain as posted.
