Lease + Revenue Accounting Infrastructure
NEWv5.1 — Revenue Recognition Advanced now live

Your AI stack is useless
until your accounting
is usable.

Ledger Layer is the lease and revenue accounting infrastructure AI agents connect to — and that humans govern. Three endpoints. One deterministic engine. Full audit trail. Run IFRS 16 / ASC 842 leases and IFRS 15 / ASC 606 revenue contracts on the same engine. Connect your agent via MCP, upload from Excel, or integrate your ERP — your accounting data becomes structured, trusted, and queryable. Same audit controls. Zero spreadsheet risk.

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.
Your ROU asset and lease liability differ by $12,400. Source unknown.
The modification from March was never remeasured. Three closes ago.
From $49/mo · lease + revenue included · no implementation project · cancel anytime

The average lease and revenue accounting system costs $25,000/year — per module. Ledger Layer bundles both, starting at $49/month.

Two ways in

Path A — Start with data

Upload your Excel, CSV, or PDF

AI extracts lease and revenue contract terms. You review and confirm. Engine runs IFRS 16 / ASC 842 and IFRS 15 / ASC 606 side by side. Audit-ready output in minutes — no implementation project.

Get started
Path B — Start with agents

Connect Claude, GPT, or any MCP client

Query your accounting data in under 5 minutes. Generate an API token, point your MCP client at Ledger Layer, and your agent has structured, role-gated access to the engine.

View MCP setup

Both paths use the same deterministic engine, the same audit trail, and the same approval gates.

Pricing

Same engine, every tier. Lease + revenue included. No implementation project.

Lease accounting systems cost $25K–$100K/year. Revenue recognition systems usually cost the same again. Managed services run $50K–$200K/year. Ledger Layer bundles lease and revenue from $49/month — same engine, same audit trail.

Same deterministic engine, every tier. Both lease and revenue modules included from day one. No per-seat pricing. No per-agent pricing. No implementation project. You pay for how many legal entities you run — not how many users you add. Professional automatically receives every new module added to the roadmap, free.

Your next close is your last manual close.

Upload your Excel or connect your agent. Audit-ready output in minutes — no implementation project.

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

Clean, structured, trusted data
Your AI assistant, SAP, Oracle, CRM — all operating on the same deterministic accounting layer

The architecture

Agents extract. Engine computes. Humans govern.

Three layers. Three API endpoints. One immutable data contract. AI extraction → deterministic engine → human approval. The architecture that makes accounting data trustworthy for AI — without compromising the controls auditors require.

Layer 01

AI extraction

Reads your Excel, PDF, or plain-language description. Extracts and normalises relevant data. Proposes data for your review. Never computes a single accounting number.

proposals only
AI has zero access to compute functions. All accounting outputs come from the engine — never the AI layer.

AI reads structure — not your numbers. Only structural metadata is passed to AI models. No financial data, no cell values, no PII. All accounting computation runs in the deterministic engine.

AI proposals are never authoritative. They require engine validation and human approval before any value is recorded.

Layer 02

Deterministic engine

Version-pinned IFRS and US GAAP logic. Accounting calculations, schedules, Journal entries, and Disclosures — computed deterministically. Same inputs always produce the same hash-verified output.

Trusted math · hash-verified
Maturity analysis PV tie-out validated to $0.01 delta before any disclosure pack is written. Rejected automatically if it fails.

This is the only layer permitted to compute accounting output.

Layer 03

Human approval authority

You review the journal entry. You approve it. Once approved, it is immutable — no delete, no edit, reversal only. Nothing exports to your ERP until this step is complete. This is where your company's sign-off authority lives — not with the software.

Approval-gated · immutable
Approved JEs cannot be deleted or modified. Only an explicit reversal JE — itself approval-gated — can correct them.

AI can propose. Only humans can approve.

The problem

Your accounting is disconnected from AI.

Excel is not a system. It's a file. AI tools can't query it safely. Manual pipelines break under audit. The data your AI needs is locked in a format it can't trust.

Without Ledger Layer — the pre-AI era
Closed data. No API. Your AI stack and your accounting live in separate silos — by design.
No agent interface. Claude, GPT, n8n — none of them can reach your accounting data safely.
3–5 days per entity, per close. Reconciling workbooks, rebuilding disclosures, chasing versions. Every quarter.
vs
With Ledger Layer — AI-native infrastructure
Open protocol. MCP-native. AI agents connect directly to structured, audit-grade accounting data.
One deterministic engine. Agent reads. Engine computes. Human approves. Architecture enforced.
Close in hours, not days. Idempotent monthly close, per-entity. Disclosure pack reconciles automatically.

Not another SaaS app. Accounting infrastructure.

Supported standards

IFRS 16ASC 842
Lease Accounting
Right-of-use assets, lease liabilities, amortisation schedules, modification events, short-term and low-value exemptions, maturity analysis, disclosure packs.
IFRS 15ASC 606

IFRS & US GAAPDual-standard entities supported across all modules

Every quarter, your team spends 3–5 days per entity reconciling lease and revenue workbooks, rebuilding disclosures, and chasing versions. For a 10-entity group, that is 30–50 person-days a year on close mechanics. On Ledger Layer, a close takes hours — across leases and revenue contracts.

Stop bleeding person-days to spreadsheet mechanics.

Move off Excel. Get hash-verified output. Keep the controls auditors require — no implementation project.

A — Agent & API surface

MCP endpoint

75+ schema-validated tools. Any MCP-compatible agent connects immediately — Claude, GPT, n8n, or your own. Same approval gates as a human.

Ingestion API

Upload Excel, CSV, or PDF. AI reads the workbook structure and extracts lease and contract terms. You confirm. Engine runs. 200 leases in under 60 seconds.

REST API

Full OpenAPI 3.1 spec. Every engine operation is API-addressable — lease runs, journal approvals, disclosures, structured journal export. Webhooks for event-driven automation.

Normalisation layer

Raw lease and contract data structured into a clean, queryable schema. The same schema your AI agent, ERP, and CRM all read from — consistently.

Journal export

Approved journal entries in structured CSV, XLSX, and JSON — ready to feed into SAP, Oracle, NetSuite, or any iPaaS (Alteryx, n8n, Workato, Zapier, Airflow) via the tool of your choice. Full posting_reference lifecycle.

Tenant isolation

Owner, Admin, Approver, Preparer, Reviewer. Role-gated at the API layer. Same permissions for agents and humans. Complete tenant isolation on every call.

B — Deterministic compute

Deterministic engine

IFRS 16, ASC 842, IFRS 15, ASC 606 — version-pinned. Present value, amortisation, revenue recognition. Hash-verified on every run. Same inputs always produce the same output.

Journal entry approval

Role-gated approval. Approved JEs are immutable — reversal only. Full audit trail on every write: actor, timestamp, request ID.

Disclosure packs

IFRS 16 para 53–58 and ASC 842-20-50 compliant packs, auto-generated. ROU movements, maturity analysis, weighted average IBR. PV tie-out validated to $0.01.

Multi-currency & IBR matrix

IBR rates by currency × term × effective date. Every rate traces to a persisted source row. Full FX traceability across unlimited currencies.

Monthly close

Close your entire portfolio in one operation. Idempotent, concurrency-safe, re-runnable. Every close produces a complete, reviewable audit record.

Self-hosted / Mode 3

Docker image, your infrastructure, your local AI provider. The deterministic engine runs identically in all three deployment modes. No data leaves your network.

FAQ

Audit, AI, and control questions answered.

How does Ledger Layer compare in cost to other lease and revenue accounting systems?+
The average enterprise lease accounting platform costs $25,000/year (source: Vendr/Finantrix 2026 data) — and revenue recognition typically requires a separate vendor at similar cost. Big 4 managed services run $50K–$200K/year. Ledger Layer Starter is $49/month ($588/year) and includes both lease and revenue modules. Professional is $499/month ($5,988/year), bundles both modules, and automatically includes every new module added to the roadmap (IFRS 9, ASC 326 / CECL, hedge accounting, IFRS 17, share-based payment, taxes, business combinations, and more) at no extra cost. Same deterministic engine. Same audit trail. Same hash-verified output. No implementation project. No per-seat pricing. No per-agent pricing.
Can AI be trusted to run accounting on its own?+
No. AI can interpret and suggest, but it cannot guarantee deterministic, audit-grade outputs. Language models are probabilistic — they produce plausible answers, not verified ones. Ledger Layer separates interpretation from computation: AI extracts and normalises data, but all accounting results are produced by a deterministic engine with human approval. This separation is enforced architecturally, not just by convention.
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 — present value, amortisation, revenue recognition, journal entry amounts — are performed exclusively by the deterministic engine. The AI has zero access to any compute function. Your auditors can rely on every number.
Can I import our existing Excel model?+
Yes. Ledger Layer accepts Excel uploads directly. The AI reads the structure of your workbook, extracts lease and contract 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.
What if I approve a wrong journal entry?+
Once approved, a journal entry is immutable — no delete, no edit. The correct treatment is an explicit reversal JE, which itself goes through the full approval workflow. This mirrors standard accounting practice and produces a clean audit trail.
How are IFRS 16 lease modifications handled?+
The engine supports the full range of modification events: extensions, early and partial terminations, remeasurements for variable-in-substance payments, and rate changes — all per IFRS 16 and ASC 842 prescribed treatment. Each modification triggers a remeasurement run from the modification date, producing updated schedules and modification-event journal entries.
We have leases in 12 currencies. Any issues?+
None. FX and IBR rates live in dedicated tables. Every calculation traces back to a specific persisted rate row — effective date, source, and who uploaded it. The IBR matrix supports currency × term bucket × effective date across unlimited currencies.
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.
Can we run Ledger Layer on our own infrastructure?+
Yes — Mode 3 (Self-Hosted). Docker image, your infrastructure, your local AI provider. The deterministic engine runs identically in all three deployment modes. No data leaves your network. Available on the Enterprise plan.
How are roles and permissions structured?+
Four roles, each with distinct authority:

OWNER — Full workspace control. Manages billing, users, and all approval authority.
ADMIN — Can approve journal entries, manage entities, and configure workspace settings. Cannot manage billing.
PREPARER — Can upload data, run the engine, and draft journal entries. Cannot approve their own work.
REVIEWER — Read-only access to portfolio, journals, disclosures, and audit trail. Cannot modify data.

Same roles apply to human users and AI agents. An agent with a PREPARER token can extract and compute but cannot approve. Enforced at the API layer. MFA is enforced for ADMIN and OWNER.
