Some customers buy from you under more than one registered tax number — for example, a chain business with separate GST registrations for different branches or locations. Instead of editing that customer’s profile every time you bill a different branch, BillBasket lets you save each tax number as a named branch on the customer, then pick the right one while billing.
This is different from a product or category’s tax rate — branches don’t change how much tax is charged, only which tax number and billing address print on the invoice for that customer.

​
Understanding the fields

Each saved branch on a customer has:
  • Label — a name you choose to tell branches apart, like “Sales A” or “Main Branch.” This is what you’ll see and pick from at billing time, so make it something you’ll recognize later.
  • Tax number — the GSTIN (or equivalent) for that branch. This is what gets printed on the invoice and saved permanently against that specific bill, so changing or deleting the branch later doesn’t alter past invoices.
  • Address — the billing address that goes with that branch’s tax number, since a different registration usually means a different registered address.
  • Place of supply — which state/region the sale is treated as being made to, for your own tax records.
  • Default branch — a customer can have only one branch marked default at a time. The default is what’s pre-selected when you pick that customer on a new invoice, so the common case needs no extra taps — you only need to switch branches for the exception.
  • Active — an inactive branch stops showing up as an option at billing time without deleting its history from past invoices.

​
Why this matters

Because the tax number is snapshotted onto the invoice at the moment you bill it (not looked up live from the customer each time), an old invoice keeps showing the branch that was actually used — even if you later change that customer’s default branch or edit a branch’s details.

1

Pick the customer on a new invoice

Rajesh Sharma starts a new bill for a regular wholesale customer that operates two registered branches, and picks that customer as usual.
2

Add a tax branch instead of retyping the tax number

Since this is the customer’s first bill in BillBasket, Rajesh adds a branch with a label (“Main Branch”), that branch’s tax number, and its billing address — and marks it as the default.
3

Switch branches when billing a different location

The next month, the same customer orders for their second branch. Rajesh adds a second branch (“Warehouse Branch”) with its own tax number and address, and picks it instead of the default for this invoice only.

Past invoices keep the branch that was actually used

Later, Rajesh reprints last month’s invoice — it still shows “Main Branch” and its tax number, even though the customer’s default has since changed, because the invoice saved a snapshot of what was picked at the time.
