AI-integrated accounting
The accounting platform you can talk to.
Keep your small-business books by asking. Connect Claude and Lejr turns “I bought a forklift for $75k” into proper double-entry accounting, ready for tax season. Multi-entity, audit-trailed, balanced to the penny.
The inversion
Clicking through menus is not how you think about your business.
The others
47 clicks
to categorize 100 bank transactions — one at a time, through a dropdown menu.
Lejr
one sentence
“Categorize all Shell and Chevron transactions as Fuel.”
AI-integrated accounting
Built for Claude. More AI to follow.
Lejr is built around the assumption that you talk to an AI about your books. Claude is supported today — connect it once, and your assistant gets a new skill: keeping your books, balanced to the penny, on the audit trail.
ChatGPT, Gemini, and Copilot integrations are on the roadmap. The web app is fully capable on its own — the AI is a power-up, not a prerequisite.

The books are the books
Built like real accounting, not a spreadsheet with a chatbot.
Balanced
Your books can’t drift out of balance.
Every entry has to balance to the penny before it’s saved. Lejr won’t let you skip that — and neither will your AI. It’s the whole reason double-entry exists.
Immutable
Nothing gets quietly edited.
When something changes, the original entry stays, and the new one points back to it. Your accountant — and the IRS, if it ever comes to that — see the whole story, not just the final number.
Audited
Every change is on the record.
Who asked, what they asked, what Lejr did, and when. One screen, in plain English. If you ever need to explain a number a year from now, it’s right there.
CPA-ready
Made for your CPA, not against them.
Your accountant can open the books, pull a trial balance or general ledger, and reconcile without fighting the app. Export to QuickBooks or Xero is on the roadmap — you’re not locked in.
Pricing
Three tiers. Every feature on every one.
Pick a tier by volume, not features. Multi-entity support, all reports, MCP integration, free historical import — included everywhere.
