Your business profile is the identity that prints on every bill — your name, address, GST number and more. You set this up when you first opened Yojika; you can change it any time in Settings under the Business profile card.
Change your details
In Settings, find the Business profile card and edit any field:
- Business name — your shop’s name. This is required.
- Registered for GST — turn on if your shop has a GST number.
- GSTIN — your 15-character GST number (for example
33ABCDE1234F1Z7). Only shown when GST is on. - Invoice prefix — the letters before each bill number, such as
INV. - State (place of supply) — your state.
- Phone, Email, Address — your contact details, which print on your bills.
When you are done, click Save changes.
Turning GST on or off
Use the Registered for GST switch:
- On — your bills charge GST and print as “TAX INVOICE”. You must enter a valid GSTIN to save. Your state is set automatically from the first two digits of your GSTIN, so the state box is locked.
- Off — your bills are plain bills with no tax. You choose your state yourself from the list. If you had a GST number before, Yojika keeps it on file for when you turn GST back on.
About your state
Your state matters for GST. When you bill a customer in your own state, the tax is split into CGST and SGST. When you bill a customer in another state, a single IGST is charged instead. Yojika works this out for you from your state and the customer’s state — you do not have to do anything.
The invoice prefix
The invoice prefix is the short text at the start of every bill number, like the INV in INV2025-26/0001. Change it here and every new bill uses the new prefix. It does not change bills you already made. To see how the full number is built, see How invoice numbers work.
