InvoiceNow Grants & Onboarding Q&A

Find answers on eligibility, claiming procedures, and how HeyInvoice, built on an IMDA-accredited Access Point, helps you qualify for transition funding.

Eligibility is categorized into three distinct business tiers based on GST status and integration needs:

  • GST Transition Grant ($1k): Open to Singapore GST-registered businesses with annual supplies ≤ S$4M. Requires adopting an accredited IRSP or integrating own ERP after 26 Feb 2026.
  • GST Transition Grant ($5k): Open to GST-registered businesses with annual supplies > S$4M. Must integrate own ERP via an accredited Access Point.
  • InvoiceNow Queen Bee Grant ($25k): For large enterprises (turnover > S$4M, ≥200 suppliers/customers) connecting their own ERP and transacting with at least 20 suppliers or 40 customers.

Grantees must submit required evidence and proof-of-work via a Form.SG link that will be made available starting 1st July 2026. Required submission items include:

  • Evidence of Costs: Official purchase invoices showing the solution fee or development fee.
  • Proof of Payment: Bank transfer slips or receipts indicating complete payment to the solution provider.
  • Proof of Work/Activation: System screenshots or logs demonstrating active GST InvoiceNow submission and that invoice transaction data has been successfully sent to IRAS.

HeyInvoice is e-invoicing software built on SESAMi, an IMDA-accredited Peppol Access Point, designed to make compliance and grant qualification straightforward:

  • Automated IRAS Reporting: Once GST InvoiceNow submission is activated, invoice data is transmitted to IRAS through the Access Point each time an invoice is sent, satisfying the grant requirement of "activating GST InvoiceNow submission".
  • Accreditation: Every document is transmitted through SESAMi, an IMDA-accredited Peppol Access Point. HeyInvoice's own IMDA InvoiceNow-Ready Solution Provider (IRSP) accreditation is in progress.
  • Seamless ERP Integration: For the $5k and $25k grants, our developer-friendly APIs and middleware let you hook up ERPs (like SAP or Microsoft Dynamics) and start transacting immediately.
  • Compliance Documentation: Transmission records, IRAS acknowledgements and billing statements can be exported to support your grant claim on Form.SG.

Deadlines depend on the specific incentive:

  • Incentive Launch: All business-facing grants open for application on 1st July 2026.
  • GST Transition Grant ($5k): Pinned ERP projects must begin after 26 Feb 2026 and complete work before 31st March 2028.
  • Queen Bee Grant ($25k): Work must start between 1 Jul 2026 and 31 Mar 2030, with transaction requirements met by 31st March 2031. This grant is disbursed on a first-come, first-served basis.
