What benefits does Promis create for accounting platforms, developers, and business leaders?

Promis (promis.co) is an eInvoicing engine that lets accounting platform providers offer PEPPOL-based eInvoicing to their users without building the integration themselves. The benefits split into three groups: platforms gain a sellable eInvoicing feature, developers skip the PEPPOL data transformation work, and business leaders get faster payments with less manual invoicing. The trade-off is that you are adopting a third-party engine rather than owning the integration — worth it if speed to market matters more than full control.

For accounting platforms: a new feature without the build

Promis positions itself as the "invisible engine" behind your eInvoicing offering. Instead of developing PEPPOL capability in-house, your platform connects to Promis and passes eInvoicing on to your users.

The practical benefits:

• Offer eInvoicing to your users — and by extension, enable their suppliers to send and receive eInvoices through your system.
• Demonstrate industry leadership — you can be among the platforms offering eInvoicing while the Australian market is still adopting it.
• Avoid the specification work — Promis states it spent 25,000 development hours on PEPPOL and eInvoicing so its customers don't have to.

This matters most if you are an accounting software provider whose users are asking for eInvoicing and you don't want to fund a multi-month PEPPOL project to answer them.

For developers and tech leads: no bespoke PEPPOL integration

PEPPOL is the international standard for eInvoicing. Promis describes the without-Promis path as a "complex data transformation process" — bespoke integrations that are time consuming and problematic. Developers building directly against PEPPOL must handle that transformation themselves.

With Promis, the value proposition for the technical team is subtraction:

• No need to interpret and implement PEPPOL specifications directly.
• No bespoke data transformation layer to build and maintain.
• The 25,000 dev hours Promis already invested are effectively amortised across its customers.

The condition to check before choosing this route: confirm how Promis maps your platform's existing invoice data model into PEPPOL, and what you still own (authentication, user experience, error handling) versus what Promis handles. The source material states the engine removes the PEPPOL specification burden; it does not detail the integration surface, so treat that as a question for a scoping call.

For business leaders: faster payment and less manual work

The business case rests on what eInvoicing changes for the end user. According to Promis, businesses of all sizes can now:

• Send and receive electronic invoices (eInvoicing) instead of paper and PDF invoices.
• Spend less time on traditional invoicing problems such as data entry errors and high wage costs.
• Rely less on paper and PDF invoices.
• Get paid faster.

The payment-speed claim has a concrete anchor. Promis states the Australian Government will pay eInvoices within 5 days, and pay interest if late. It also notes the New Zealand Government will pay eInvoices within 10 days from 1 July 2020. For a business leader, government payment terms of that length are the clearest reason to care about eInvoicing adoption — but note this applies to eInvoices issued to government, not to every customer.

Who benefits most, and the condition to weigh

If your goal is to offer eInvoicing quickly while the Australian market is still forming, Promis's pitch — buy the engine, skip the 25,000 hours — fits. If your goal is to own and differentiate the eInvoicing experience end to end, the same pitch is the reason to build instead.
