Frequently asked questions

These answers are also published as structured data for search and answer engines.

Are these whitepapers free, and is registration required? +
They are free and there is no form, no gate and no registration. Every whitepaper is published in full as a web page so it can be read, linked and quoted directly.
Who writes them? +
They are written by GoRoute.ai engineering, drawing on production integration work across Peppol, national clearance regimes and enterprise ERP estates. Each paper records the date it was last reviewed.
Which whitepaper should I start with? +
If you are connecting an existing ERP, start with the Oracle and SAP integration paper. If you run high-volume retail sites, start with the fuel retail and forecourt paper. If you operate several legal entities that trade with each other, start with the multi-entity group paper.
Do these cover country-specific requirements? +
Partly. The whitepapers cover architecture that holds across jurisdictions and call out national specifics where they change the design, such as Oman's Fawtara five-corner model. Country-by-country requirements are maintained separately on our compliance pages.
Can I share or quote from them? +
Yes. They are public technical documents intended to be cited. A link back to the source page is appreciated so readers reach the current version, since the papers are revised as specifications change.
