GSTIN Capture for B2B Customers
Validated GSTIN on every B2B invoice
Save your customers' GSTINs once. They auto-populate on every invoice, properly formatted and validated — your CA will love you.
What do you get out of it?
Capturing a customer's GSTIN once settles three things for every future bill: whether the invoice is B2B, which tax split applies, and whether you need to collect their name and address. You stop deciding any of it at the counter.
How does it work?
- 1
Saved on the customer, copied onto the invoice
The GSTIN is stored against the customer record and written onto each invoice raised for them. The invoice keeps its own copy, so the document stays accurate even if the customer's details are later edited.
- 2
The first two digits decide the tax split
Every Indian GSTIN begins with a two-digit state code. Wiseventory reads it, checks it against the state list, and compares it to your own state — same state gives CGST plus SGST, different gives IGST. Nobody at the counter decides this.
- 3
It sets the place of supply
Place of supply is derived from the customer's GSTIN rather than from free-text address matching, which is why B2B invoices stay consistent even when addresses are entered inconsistently.
- 4
It carries through to your returns and your CA
The GSTIN lands in your GSTR-1 B2B tables, and travels into the Tally export as part of the customer ledger — so your accountant receives party details rather than bare names.
What situations does it handle?
A B2B customer is exempt from the ₹50,000 details gate
Under CGST Rule 46(f), B2C invoices at or above ₹50,000 must carry the recipient's name and address. A customer with a GSTIN is outside that gate, because the GSTIN already carries the required identity — so Wiseventory does not prompt you for details you have.
A walk-in who turns out to be a business
Capture the GSTIN and the invoice becomes B2B, with the tax split following from the state code. The decision is driven by whether a GSTIN is present, not by a mode you had to choose in advance.
Customers across many states
State codes are resolved against the official list, so a business selling into a dozen states gets the right treatment on each invoice without anyone keeping a mental map of which code belongs to which state.
How do you get more out of it?
- Capture the GSTIN the first time a business customer buys. From then on the tax split, the place of supply and their B2B status all follow automatically.
- Copy it from the customer's own invoice or their GST certificate rather than typing from memory — everything downstream reads from this one field.
- It travels into your GSTR-1 B2B tables and into the Tally export as part of their ledger, so your accountant receives identified parties.
- For a large new account, a quick check on the GST portal that the registration is active is worth the minute it takes.
Common questions
How does saving a GSTIN change the tax on my invoice?
The first two digits are the customer's state code. Wiseventory compares that to your state and applies CGST plus SGST when they match, or IGST when they differ. Because the decision comes from stored data rather than a choice at billing time, interstate invoices stay consistent even on a busy day.
Do I need the customer's address as well?
For a B2B customer with a GSTIN, the ₹50,000 name-and-address requirement under Rule 46(f) does not apply, because the GSTIN carries that identity. For B2C sales at or above ₹50,000 you will be prompted for the recipient's details.
What does my accountant see?
The GSTIN appears in your GSTR-1 B2B tables and comes across in the Tally export attached to the customer's ledger. They receive identified parties rather than a list of names they then have to match up.
What is the fastest way to set up my regular B2B customers?
Capture each one's GSTIN the first time they buy, straight from their own invoice or GST certificate. That single entry then decides the tax split, the place of supply and their B2B status on every future bill — so the work is front-loaded once per customer rather than repeated on every sale.
