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

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.

Ready-to-use Portal

For SMEs

Send and receive InvoiceNow e-invoices without a complex IT project. We support Peppol registration and IRAS submission, so you can get on the network and start transacting from a browser.

ERP and Finance Software Integration

For Enterprises

Connect Staple to your current ERP and finance systems to automate invoice processes, reduce manual work, and improve operational efficiency, all at the volume your business runs on.

Embedded & White-labelled API

For ERP Providers

Offer InvoiceNow within your own experience while Staple manages network connectivity and IRAS submission. Full transaction API coverage, with each of your customers isolated as its own tenant.

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.

Process traditional and e-invoices together

Handle InvoiceNow and Peppol e-invoices alongside PDFs and scanned 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.

AP and AR

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.
