Built for the industries that make up Singapore's SME economy
The mandate is arriving in stages — and it starts with smaller businesses
To digitalise tax administration nationwide, GST-registered businesses will be required to submit invoice data straight to IRAS through the InvoiceNow network. Your exact start date depends on how and when you're GST-registered.
InvoiceNow runs on Peppol, the same e-invoicing network already used across the region. Instead of emailing PDFs or re-keying figures, invoice data moves structured and machine-readable between systems — which is what makes direct IRAS submission possible.
Winapp Accounting was built with this shift in mind, so moving early doesn't mean bolting on a second tool.
- Cut manual invoice entry by a large margin
- Cleaner audit trail for every invoice sent or received
- Faster payment cycles once data entry friction is gone

It's the IRAS initiative that lets GST invoice data reach IRAS directly through the InvoiceNow (Peppol) network, instead of being filed separately after the fact. It's being introduced in phases rather than all at once.
If you're GST-registered, most likely yes, on a timeline tied to your registration type and annual turnover. Check the deadline table above, or ask us to confirm your date.
InvoiceNow is built into the same system you already use for invoicing and bookkeeping, so sending, receiving, and submitting invoice data happens in one place rather than through a separate tool.
Many businesses qualify for PSG support and additional InvoiceNow transition funding. Eligibility varies by company, so we walk you through the specifics before you apply.
Moving early gives your team time to adjust, reduces manual invoice work sooner, and means you're not implementing under time pressure right before the cut-off.
