Global E-invoicing Compliance now supports Singapore, so if your compliance deadline is already here or still ahead, you can get connected today without building anything from scratch.

Singapore's GST InvoiceNow mandate uses a five-corner model that creates two simultaneous obligations for every GST-relevant invoice: deliver it to your trading partner via Peppol, and submit a copy directly to IRAS via API. Only IMDA-accredited Access Points can handle that IRAS submission, and ecosio is accredited.

What we built for you

• Dual delivery in a single flow: Peppol delivery and IRAS reporting run as coordinated steps in a single integration path, so you don't manage two separate connections.

• Wide document support: Tax invoices, credit notes, debit notes, simplified tax invoices, and self-billed invoices.

• PINT SG transformation and validation: We prepare your documents for Peppol InvoiceNow using PINT SG, then validate the IRAS copy against the IRAS Schematron before submission.

• CorpPass activation support: We manage the authorisation workflow so ecosio can submit on your behalf.

• Visibility in Monitor: You can track submission status, acknowledgement IDs, and error codes in one place, so you catch issues before they become penalties.

When you need to comply, we're ready
