Run your Singapore business on one platform — with GST handled properly.
GST at 9% computed on every line, GST Reg. No. validation, and invoices carrying the particulars the law requires. Alongside the clients, projects, people and field teams that produced the invoice in the first place.
What Grovia does for a business in Singapore
The tax engine is not a rate field bolted onto a template. It is cited to the legislation and shared by every document the platform prints.
GST that is actually computed
Every line carries its own rate and the totals are worked out for you. Set 0% where a supply is zero-rated or exempt and Grovia records which, because the two are not interchangeable at your year end.
GST Reg. No. validation
The GST registration number in its own right, not the UEN it resembles. Grovia checks the shape and stops there: a check character demonstrably exists, but no algorithm is officially published — IRAS's own instruction is to look the number up on uen.gov.sg — and the weights circulating online are unofficial reverse-engineering.
Invoices that carry what the law asks for
A sequential number, both parties' details, your GST Reg. No., the rate and amount per line and the tax total — the particulars the GST (General) Regulations 1993 sets out, printed without you assembling them.
Nothing is assumed from an address
A customer being overseas does not make a supply zero-rated, and Grovia never pretends otherwise. Place of supply turns on facts software cannot see, so the decision stays yours and the record shows you made it.
The rest of the business, same platform
Clients, quotes, projects, tasks, staff, payroll, expenses, support tickets and field visits. The invoice is the end of a workflow that already lives here, not an export into something else.
On the phone as well
Grovia Chat for the team, Grovia Field for people on site with GPS check-ins and photo reports, and GroAI for asking your own numbers a question in plain English.
Working today
- GST at the standard rate, applied per line item
- Tax invoices carrying the particulars enumerated in Regulation 11
- Singapore dollar totals on an invoice in another currency, at the exchange rate you enter, as Regulation 11(1)(k) requires
- Simplified tax invoices under Regulation 13 for a sale of S$1,000 or less including GST, refused with the reason when one of its conditions is not met
- GST registration numbers validated by format, in both the alphanumeric and the older numeric shapes
- Quotes, credit notes, purchase orders and receipts in Singapore dollars
- Zero-rated and exempt lines, when you set them — never guessed from a customer's address, because section 21(3)(j) turns on where the benefit accrues rather than where the customer is
Invoices are issued citing Regulation 11 of the Goods and Services Tax (General) Regulations 1993, made under the Goods and Services Tax Act 1993.
Not handled yet — worth knowing before you sign up
We would rather you read this now than find it after you have paid. If any of the below is central to how you bill, Grovia is not the right fit for that part of your work yet.
Payroll follows Indian rules
Grovia's payroll prices basic pay, HRA and a percentage provident fund the Indian way. It does not calculate CPF contributions by age and residency, the Skills Development Levy or self-help group deductions, and it produces no IR8A or Auto-Inclusion Scheme submission. The payroll screen says this and asks you to acknowledge it before it generates anything.
No regulation number on credit notes
Grovia prints the right fields on a credit note but cites no regulation, on purpose. Regulation 12 is the one that looks right and is not: it governs only credit notes arising from a rate change or a section 39B election. An ordinary commercial credit note's field list is IRAS administrative guidance, not a numbered provision, so there is nothing honest to print.
Exchange rates are not checked
Grovia prints the Singapore dollar totals at the rate you enter and does not check it. The GST Act (Third Schedule, paragraph 11) names the selling rate prevailing in Singapore at the time of supply, unless you have opted for a rate the Comptroller has notified.
InvoiceNow
Grovia does not send or receive invoices on the Peppol network. IRAS requires InvoiceNow for newly incorporated companies that register for GST voluntarily from 1 November 2025, and for all new voluntary GST registrants from 1 April 2026; existing GST-registered businesses are phased in from 1 April 2028 to 1 April 2031. If your business already falls in one of those groups, Grovia cannot send your invoices through InvoiceNow for you today.
