E-invoicing for Singapore Businesses | InvoiceNow accredited +PEPPOL

The problem

Your finance team is ready. The setup isn't.

Most GST-registered businesses know they need to get on InvoiceNow. What they don't expect is the setup:

Finding an accredited Peppol Access Point
Getting AP and AR both running
Keeping up with evolving IRAS requirements
Managing suppliers who aren't on the network yet

The complexity adds up faster than the team can handle.

One access point. Three ways to connect.

Staple is the access point you won't outgrow. Whether you send your first e‑invoice through a browser or run millions through your own systems, it's the same accredited network connection underneath. Start where you are today, scale when you're ready.

Why Staple

Staple does more than network access.

One platform, both directions

Process supplier invoices and send customer invoices through one platform and one connection.

Invoices and e‑invoices, together

Handle InvoiceNow and Peppol e‑invoices alongside all your other invoices, rather than running separate processes.

Reduce avoidable rejections and rework

Validate required fields and applicable InvoiceNow and PINT-SG rules before submission to identify potential issues earlier.

Simplify audit work

Retain each invoice's source, validation results, and complete processing history, sealed for easier review and traceability.

Same backbone. Both directions.

Staple handles both sides of your InvoiceNow flow from a single platform. No separate tools, no separate vendors.

AR Automation

Send compliant e‑invoices to your customer while reporting GST data to IRAS at the same time.

Ingest Extract invoicing data from your ERP or accounting system, in any format.
Validate Convert to InvoiceNow format. Check schema, identity, totals, duplicates.
Sign Sign with the IMDA-issued PKI certificate.
In parallel
4a. Report to IRAS Send GST data to IRAS via API.
