Map Locations to GST Registrations

A mapping tells Yepsta which GST registration a location uses on a particular date. It controls the supplier GSTIN and state captured on new invoices and the registration under which source records enter GST reporting.

Permission required

Only a Business Owner can create or change registration-to-location mappings. Billing users still need invoice or POS permission and access to the selected location.

Map a location

Open Settings → Locations & GST and find GST registrations & location coverage.

Create dated location coverage

1. Find the required GST registration and select Map location.
2. In Map a location, choose the Business location.
3. Enter Effective from. It must fall within the registration’s effective dates.
4. Add Effective to for a fixed period, or leave it blank for current open-ended coverage.
5. Save the mapping.
6. Repeat for every active location that should issue GST transactions under this registration.
7. Review the registrations’ mapped-location lists and the unmapped-location notice to confirm coverage.

Yepsta does not allow two mappings for the same location to overlap. When you add a valid later mapping, it can close the previous open-ended mapping on the preceding day. A future-dated mapping can therefore be prepared without changing today’s registration.

Understand tax and reporting behaviour

The billing location and invoice date resolve the supplier registration. Place of Supply is a separate invoice value:

• when its state code matches the resolved registration state, the invoice uses CGST and SGST;
• when it differs, the invoice uses IGST.

A location may operate in the same state as another location and use the same registration, or it may be mapped to a different GSTIN. Yepsta supports both patterns without deciding whether another registration is legally required.

GST Reports require one registration at a time and can then be narrowed to a mapped location. GST Compliance also prepares one registration and period at a time.

If a location is unmapped

The invoice workspace shows that GST is not enabled for that billing location/date, so GST identity and tax cannot be prepared through the normal mapped workflow. The location also lacks registration coverage for compliance data. Stop and correct the mapping rather than issuing a transaction under a guessed GSTIN.

An intentional gap between mapping dates is also unmapped. Once dated mapping history exists, Yepsta does not silently bridge the gap with old registration details.

Change coverage without rewriting history

Move a location to later coverage

1. Confirm the old registration’s final valid date and the new registration’s start date with your GST professional.
2. In Locations & GST, create the later mapping with the correct Effective from date.
3. If needed, set or adjust the previous mapping’s end date so there is no overlap or unintended gap.
4. Create a controlled invoice dated in the new period and verify the supplier GSTIN, place of supply and tax split.
5. Recheck GST Reports and the next compliance synchronization.

Existing issued invoices retain the registration snapshot captured when they were created. Mapping changes affect newly created records according to their document date. A locked compliance period prevents tax-affecting source changes until an authorized user reopens it.

Warning

Do not backdate coverage merely to make a report total appear. A backdated or future-dated mapping can change which registration Yepsta resolves for newly created documents on those dates. Verify the effective dates and preserve supporting evidence.

Important information

Yepsta supports dated location coverage but does not determine whether your business needs a GST registration in a state. Confirm registration obligations and effective dates with a qualified GST professional.

Tip

The default location helps general workspace selection; it is not a default GST registration and does not replace a valid dated mapping.
