Pros & Cons
b2brouter
Pros
Supports a wide range of e-invoicing standards (Peppol BIS, UBL, Facturae, FatturaPA, XRechnung, ZUGFeRD/Factur-X) with automatic format conversion
Accredited Peppol Access Point with ISO 27001 certification and EESPA membership
Free Basic tier available for very low invoice volumes, with affordable paid tiers (from 110 EUR/year)
Prebuilt ERP connectors (Dynamics 365 BC, Sage, Odoo, SAP) plus a REST API for custom integrations
Cons
Free Basic plan is very limited (only up to 24 transactions per year, no international invoices)
Higher-value features like legal invoice archiving and product catalogs are gated behind the top Business tier
Pricing and country coverage details are spread across multiple regional pages, making it harder to evaluate at a glance
Theneo
Pros
Free Starter plan is usable for small public or private API projects
Supports a wide range of spec formats beyond just OpenAPI
AI features cut down manual documentation maintenance work
Authenticated per-customer developer hubs are useful for B2B APIs
Y Combinator-backed with active product development
Cons
Higher tiers like Growth and Enterprise get expensive for larger teams
Self-hosting is only available on the custom Enterprise tier
AI-generated content still needs human review for accuracy
Smaller brand recognition than established players like ReadMe or Swagger
Some advanced features are workspace-limited rather than per-seat
