Adding client tax identifiers
Client tax identifiers are your client's tax registration numbers — their VAT number, GST registration, TIN, and so on. SolidInvoice prints them on the invoices and quotes you send to that client.
Where to add them
Tax identifiers are part of the client record. You can add them when creating a new client or at any time through the client edit form.
In the client form, scroll to the Tax Identifiers section (marked as optional). If no identifiers have been added yet, you will see the hint: No tax identifiers added yet. Add one if this client has a VAT, GST or other registered tax number.
Add an identifier
Click Add tax identifier. A row appears with three fields:
| Field | Description |
|---|---|
| Type | The kind of identifier. Choose from VAT, GSTIN, TIN, ABN, CNPJ, TRN, or Other. |
| Number | The client's registration number for that identifier type. |
| Primary | Mark one identifier as primary when the client has more than one. The primary identifier is emphasised on output documents. |
Repeat for each identifier the client holds.
Remove an identifier
Click the trash icon on the right of the row to remove it.
Save
Save the client form as normal. All identifier changes are saved together with the rest of the client record.
If you are registered for VAT and your client is too, recording both your own VAT number (under Company Tax Identifiers) and the client's VAT number here ensures both appear on the invoice — a common requirement for business-to-business tax compliance.
