Peppol B2B mandate live since Jan 2026 — Ledgr is ready

Accounting that opens up, instead of locking in

Peppol e-reporting ready, by design

The platform

Every module a freelancer needs, none they don't

Modular by design — turn features on per org. Start with invoicing and the inbox, add banking and AI when you're ready.

Document inbox & OCR

Email, scan, or receive Peppol invoices. Ledgr extracts the data and drafts the booking — you confirm in one click.

Banking & reconciliation

Connect KBC, Belfius, ING via Ponto. Transactions match to entries automatically with learned categorization rules.

Invoicing & Peppol

Send compliant invoices over the Peppol network, track payment with structured references, and chase overdue automatically.

VAT & Intervat

Quarterly or monthly VAT computed from your ledger, mapped to the Belgian grid, generated as Intervat XML.

Automation

Recurring entries, categorization rules, and webhooks. Set it up once and let routine bookkeeping run itself.

AI assistant

Ask about VAT, cash, or receivables in plain language. The assistant reads your real ledger and asks before posting.

Open core

Your books, in plain text, forever

Ledgr is built on Beancount — a mature, plain-text, double-entry engine. Every posted transaction is yours to export, audit, or self-host. No proprietary format, no lock-in, no hostage data.

For agencies

One workspace, every client

Agency-native from day one. Staff onboard once and access client orgs through the firm's mandate — not 30 separate invites. Mandate dates, scope, and ITAA accountability are first-class.

AI-native

Meet the LLM where it already lives

Instead of bolting a chatbot onto the app, Ledgr exposes your ledger as MCP tools. Connect Claude, ChatGPT, or Cursor and let your own AI operate on real data — with explicit confirmation for any change.

Typed tools over your ledger
Confirmation before any mutation

API-first

Built as an API, with a UI on top

Every action in Ledgr is an API call. Issue invoices, push documents, read the ledger, or wire webhooks into your own systems. Scoped API keys and an MCP server come standard.
