Lease + Revenue Accounting Infrastructure

Audit-grade accounting.
Built for the AI era.

One deterministic engine for IFRS 16, ASC 842, IFRS 15, and ASC 606. Auditable for humans, API-callable by your AI agents. Upload from Excel, connect via MCP, or integrate your ERP — same engine, same audit trail, every time. $49/month, both modules included.

Your IBR lookup returns #REF! on 3 leases. Close is in 4 hours.
That circular reference in column G has been there since Q2 2023.
The disclosure pack doesn't reconcile to the balance sheet. Again.
Nobody knows which version of the Excel model the auditors signed off on.
Someone overwrote the payment schedule on the Dubai lease. Unknown when.

AI can read your data. It cannot produce audit-grade accounting on its own.
Ledger Layer enforces the rules in between.

How it works

Three layers. Strict boundaries. One audit trail.

What makes Ledger Layer different from "ChatGPT + a spreadsheet": the boundaries between layers are enforced at the system level, not by policy.

LAYER 01

AI extraction

AI reads your Excel, PDF, or natural-language input and proposes structured records. It never touches the math. Schema-validated tools refuse anything malformed.

LAYER 02

Deterministic engine

Present value, amortisation, revenue recognition, journal amounts — all computed by code, version-pinned, with hash-verified output. Same inputs always produce the same numbers.

LAYER 03

Human approval

Nothing posts without a preparer/reviewer sign-off. Approved journal entries are immutable. Every write logged with actor, timestamp, and request ID.

Open sandbox · live now

Try it yourself. No sales call.

Watch how the engine works, connect Claude or ChatGPT to the sandbox, then ask a real question. Same engine the training runs on, same dataset. No signup, no sales call — synthetic, read-only dataset, production data is never exposed.

STEP 01 · WATCH

37-minute walkthrough. Then decide.

Built by an ex-Big 4 IFRS team. Covers the four-layer architecture, three Excel failure modes, why AI alone doesn't fix it, and three live demos against the same sandbox you'll connect to in step 2.

1 of 3

Sandbox runs on sandbox.ledgerlayer.app — separate subdomain, synthetic dataset, read-only. Production data is never exposed.

How we compare

The only AI-ready accounting layer with audit controls.

Excel can be audited but can't be queried by AI. AI can be queried but can't be audited. Ledger Layer does both.

Pricing

Same engine, every tier. Both modules included.

Lease accounting systems cost $25K–$100K/year. Revenue recognition systems cost the same again. Big 4 managed services run $50K–$200K/year. Ledger Layer bundles both from $49/month.

FAQ

Audit, AI, and control questions.

Does the AI compute the accounting numbers?+
No — and this is the most important thing about Ledger Layer. The AI layer extracts and normalises data from your inputs only. All accounting calculations are performed exclusively by the deterministic engine. The AI has zero access to any compute function.
Can AI be trusted to run accounting on its own?+
No. AI can interpret and suggest, but it cannot guarantee deterministic, audit-grade outputs. Ledger Layer separates interpretation from computation — enforced architecturally, not just by convention.
Can I import our existing Excel model?+
Yes. Ledger Layer accepts Excel uploads directly. The AI reads the structure of your workbook, extracts terms, and routes them to the engine. You review and confirm before anything is calculated. Bulk import of 200 leases completes in under 60 seconds.
Can our AI agent (Claude, GPT, n8n) use Ledger Layer?+
Yes. Ledger Layer exposes a full MCP server with 75+ schema-validated tools. Your agent connects via Bearer token with the same role-gated access as a human user. The key distinction: the agent can propose actions, but it cannot approve journal entries — that authority always stays with a human.
How does cost compare to other systems?+
The average enterprise lease accounting platform costs $25,000/year (Vendr/Finantrix 2026), with revenue recognition usually a separate vendor at similar cost. Big 4 managed services run $50K–$200K/year. Ledger Layer Starter is $588/year and includes both modules. Professional is $5,988/year and includes every future module free.
