Since 1 July 2026, GST-registered SMEs in Singapore have been able to claim a one-off S$1,000 grant to help them move onto InvoiceNow. The grant runs until 31 March 2030, or until the money runs out.
The amount is modest. The rules around it are more interesting, because they reward businesses that choose their accounting setup carefully and early.
The Timeline Is Now Fixed
InvoiceNow is Singapore’s national e-invoicing network, built on the international Peppol standard. IRAS says there are over 63,000 businesses already on it.
In February, the government confirmed that every GST-registered business will have to send invoice data to IRAS through the network. New voluntary GST registrants have had to do this since 1 April 2026. Everyone else follows in phases.
Businesses with annual supplies of S$200,000 or less, and new compulsory registrants, start on 1 April 2028. Those up to S$1 million follow in April 2029, those up to S$4 million in April 2030, and the rest in April 2031. IRAS expects about 90,000 more businesses to join the network as a result.
Support comes in three parts for SMEs. There are free InvoiceNow-ready solutions until March 2031, the new S$1,000 grant, and the existing Productivity Solutions Grant, which can cover up to 50% of eligible software subscriptions. Larger businesses can get up to S$5,000.
Reading the Grant’s Fine Print
The S$1,000 grant is for GST-registered businesses with total annual supplies of S$4 million or less, based on accounting periods ending in 2025. It is paid by PayNow Corporate, and each company can claim it only once.
The key conditions are about timing. The business must subscribe to an IMDA-accredited InvoiceNow-ready solution for at least 12 months, or connect its own system through an accredited access point, after 26 February 2026. It must then activate GST InvoiceNow and submit invoice data to IRAS before its own deadline.
Two exclusions catch people out. A business already subscribed to an InvoiceNow-ready solution does not qualify. And a business must not have used any such solution in the three months before onboarding the new one.
In practice, that means the grant favours businesses that are moving onto InvoiceNow for the first time. A company already on a compliant platform will not get it, and a company that switches between platforms carelessly may lose it.
Where the Bookkeeper Comes In
For most small businesses, the InvoiceNow decision is really a bookkeeping decision. The software the bookkeeper uses decides whether the business is ready, and the bookkeeper usually does the setup.
That makes this a good time for owners to ask their current provider three things. Which system is the company’s ledger on, and is it InvoiceNow-ready? Has anyone checked the company’s implementation date? And has the provider set up the Peppol ID and the GST submission feature, or is that still to be done?
If the answers are vague, it is worth knowing before the deadline, not after. A company that is already thinking about changing bookkeepers should also plan the move around the grant rules, so it does not end up ineligible because of timing. For owners asking what is an alternative for osome in Singapore, the first check is whether the new provider’s system is InvoiceNow-ready.
The 2028 start date feels distant. But a small business that sorts out its InvoiceNow setup now, with a bookkeeper who understands it, gets the grant, avoids a rush later, and ends up with cleaner records.
