Best Peppol API for a multi-tenant SaaS in 2026

For a multi-tenant SaaS platform, the right Peppol API is the one that matches how you onboard and manage customer legal entities — not a universal winner.

Short answer

Platform fit
Choose getpeppr when one master API key must manage many customer Legal Entities, you want a TypeScript SDK and CLI, and getpeppr's published country coverage matches your rollout.
Alternative fit
Choose another provider when you need broader direct infrastructure, a different SDK language, fully API-bootstrapped onboarding, or enterprise AP automation. The verified comparison below names the trade-offs.

Ordinary Peppol invoicing from France works today; French regulated CTC is not yet open in production.

"Market focus" reflects each provider's published positioning and country-framework coverage. It does not prove that every sender can onboard or that every national tax flow is supported. Details verified against the linked official sources on 2026-09-19; re-check before deciding.

Why "multi-tenant" changes the question

A normal Peppol integration assumes one company sending its own invoices. A SaaS platform is different: each customer is a separate legal entity on the network. These are the criteria that actually matter.
Tenant model
One company sending its own invoices is easy. A SaaS platform needs one integration with N legal entities underneath it — each customer is a separate Peppol participant — not one account per customer.
Programmatic onboarding
Can you register a tenant and mint its per-tenant credentials via API, or does every new customer need a manual setup or a sales call?
JSON in, no XML
You send your data shape; UBL / Peppol BIS Billing 3.0 is generated, validated, and transmitted for you. No XML schemas in your codebase.
Try before you buy
Can you evaluate without a signup wall or a demo call? Offline validation and instant sandboxes shorten the path from curiosity to first invoice.
Certified Access Point backing
A certified Peppol Access Point handles network transport, certificates, and Peppol rules. Fiscal compliance, invoice content, sender onboarding, and national tax flows still need to be checked separately.
Mandate roadmap & pricing model
Check which country-specific layers are live, which are piloted, and whether adding tenants or volume changes the contract, monthly fee, or per-document price.

The providers, fairly

No single provider wins on every axis. Here's where each one is strongest — facts verified on 2026-09-19.
getpeppr (opens in a new tab)
A TypeScript-first Peppol SDK built for SaaS platforms. Its Platform API uses one master API key to manage multiple customer Legal Entities, with per-tenant authorisation and webhooks. The CLI can validate and convert invoices offline without an account. Sandbox access is self-serve; Platform production access requires an Order Form and DPA. Customers are self-serve in France, Belgium, Ireland, the United Kingdom, the Netherlands, Denmark, Germany, Sweden, Norway, Estonia and Iceland. Ordinary Peppol invoicing from France works today; the regulated CTC flow for the September 2026 mandate is not yet open in production. Consider getpeppr when that tenant model, the TypeScript tooling, and the published country coverage match your rollout.
Storecove (opens in a new tab)
A certified Peppol Access Point with a RESTful JSON API, OpenAPI/Swagger documentation, and published compliance coverage in 31 countries. Storecove positions the product for ERP integrators and platforms, offers a requested 30-day test account, and activates production after contract. Pricing is quoted per integrator: the published route is a consultation or a test-account request rather than a rate card. Consider it when direct Access Point infrastructure and broader country-framework coverage matter more than a self-serve product path.
e-invoice.be (opens in a new tab)
A certified Belgian Access Point offering JSON-to-UBL, a free sandbox, multi-tenant account management, SDKs in TypeScript, Python, PHP, Ruby and Java, plus an MCP server. Published pricing starts at EUR 0.25 per invoice, with Enterprise from EUR 0.18 and no monthly minimum. Production follows KYC. Consider it when multiple SDK languages and a per-document model fit your platform.
peppol.sh (opens in a new tab)
A developer- and agent-centric REST API that accepts JSON, produces Peppol BIS 3.0 UBL, and supports one Company per tenant through its Connect model. Sandbox signup, keys and KYC are API-driven; published pricing has no monthly or per-tenant fee. It publishes a TypeScript SDK on npm; Python and PHP are announced as coming soon. Consider peppol.sh when API bootstrapping and agent-driven workflows are the priority.
Basware (opens in a new tab)
An enterprise e-invoicing network and AP automation platform with Network REST APIs plus documented XML integration paths. A subscription is required, pricing is provided by Basware, and a free testing account is provisioned through Basware Support. Consider it when enterprise AP automation and global network breadth are the primary requirements.

Full type safety, and offline validation from the terminal with no account required — try before you sign up.
Published Platform pricing
One Platform plan: a monthly fee, per-document usage, 50 customer Legal Entities included, and no per-customer minimum.
Certified Access Point underneath
Storecove handles Peppol network transport and certificates. National tax-flow support remains country-specific and is published separately.

Sources and methodology

Each provider row was checked against the provider's own public pages on 2026-09-19. We compare published tenant model, tooling, pricing, onboarding and market positioning. A sandbox claim is not treated as a measured production-delivery time, and Peppol connectivity is not treated as proof of every national tax flow.

Frequently asked questions

What is the best Peppol API for a multi-tenant SaaS?

For SaaS platforms sending invoices on behalf of many customers, the deciding factor is a native multi-tenant model — one API key, many legal entities, with per-tenant onboarding via API. getpeppr is purpose-built for that case; peppol.sh and e-invoice.be also support multi-tenant setups, and Storecove provides the underlying Access Point infrastructure.

Do I have to deal with UBL or XML myself?

No. With API-first providers like getpeppr, peppol.sh, and e-invoice.be you send JSON (or your own data shape) and the provider generates, validates, and transmits the Peppol BIS Billing 3.0 UBL for you.

Can I try a Peppol API before signing up or talking to sales?

Yes, but the path differs. getpeppr offers offline CLI validation, a hosted MCP server whose public tools Claude Code and Codex can use without an account, and a self-serve sandbox; e-invoice.be offers a free sandbox; peppol.sh can create a sandbox account through its API. Storecove offers a 30-day test account by request, and Basware provisions a free testing account through Support.

How can I check whether a company is already on the Peppol network?

Use the free Peppol participant lookup at getpeppr.dev/peppol-lookup — no signup needed. Enter a company's VAT or registration number and its scheme to see whether it is registered on Peppol and which documents (invoice, credit note) it can receive.

Which countries does the EU e-invoicing mandate cover, and when?

Belgium mandated B2B e-invoicing from 1 January 2026. Germany has phased requirements underway. France's rollout began on 1 September 2026. The EU's ViDA package extends digital reporting requirements for cross-border B2B by 1 July 2030. Peppol connectivity does not by itself prove national tax-flow coverage, so check each provider's published country capabilities.

What does "multi-tenant" mean for Peppol e-invoicing?

Each of your customers is a separate participant on the Peppol network with its own identity. A multi-tenant Peppol API lets your platform register and send for all of them through a single integration, instead of standing up a separate account per customer.
