Level Open Finance
Find missing invoices, understand margins and plan your cash.
Choose from 20 free finance checks for billing, spending, cash flow and month-end review. Each one shows the records you need, how the check works and what to do with the result.
The examples use invented records so you can follow the calculation without a software login. To use a check in your business, your finance team needs to review your actual records before acting. A skill is a reusable set of instructions for an AI assistant. Your bookkeeper, finance team or developer can use it to organize a review; downloading it does not connect it to your accounting software.

Start with one painful workflow
Meet the Revenue Leak Detective
A practical finance skill for finding completed work that may never have reached an invoice. It connects the records with the operating questions, then prepares each resolved explanation for a review history your team maintains. Saving or exporting runs in your agent or workspace; the shipped MCP server is read-only and returns frozen synthetic sample records, not your live data. Applying the checks to your records happens in your own agent or workspace.
The Level judgment loop
AI does more of the work without pretending to make the final call
Record finance judgment
We capture the checks, possible explanations, evidence requirements, and questions our finance professionals actually use.
Let AI investigate
AI applies that recorded judgment to organize evidence and plausible reasons, while preserving uncertainty.
Make the human decision
A finance professional validates the evidence, challenges the analysis, and talks the owner through the action.

Six common finance problems
Start with the number you trust least: cash, margin, billing, spend, receivables, or close.
Open finance skill
Revenue leakage review
Where could completed work be missing from billing?
Compare invented completed-job and invoice records to find work that may be unbilled, underbilled or awaiting review.

Open finance skill
Margin trend review
Why did gross margin change, and what should we investigate?
Calculate gross margin, revenue less direct costs as a share of revenue, from invented period summaries. Compare periods and flag changes large enough to review.

Open finance skill
Recurring subscription review
Which software and service charges are recurring, overlapping, or quietly increasing?
Detect recurring charges, renewal patterns, price increases, duplicate tools, and subscriptions whose owner or usage is unclear.

13-week cash-flow forecast
When does cash get tight, and which assumptions drive the outcome?
Start with verified cash, then add receipts and subtract payments each week. Include customer collections, supplier payments, payroll, taxes and debt. Keep base, better and worse scenarios separate.

Check unpaid customer invoices
Do invoice, payment, deposit, and balance records tell the same story?
Trace accounts receivable (AR), the amounts customers owe, from invoice to payment and bank deposit. Find partially paid invoices and invoices marked closed with unexplained balances.

Month-end close preview
What must be resolved before closing the month?

Open finance skill
Duplicate supplier invoice check
Which supplier invoices may have been entered twice?
Flag repeated supplier invoice numbers and similar supplier, date and amount combinations. Review the original documents before deciding whether either entry is wrong.

Supplier spending concentration
How much do we depend on our largest suppliers?
Add invented spending by supplier and category. Calculate each share of total spend so the owner can review purchasing dependencies.

Open finance skill
Check whether cost detail adds up
Does the supporting cost detail add up to the reported total?
Add invented cost-detail rows and compare their sum with the reported total. This arithmetic check is called footing. Show the difference without changing either source.

Vendor 1099 readiness
Which supplier records are missing information before 1099 preparation?
Check invented supplier records for missing classifications, tax identifiers, addresses and payment totals. This is a readiness check, not tax advice or filing software.

Cash available to earn interest
Could cash earn interest while still covering upcoming payments?
Estimate an illustrative interest opportunity only after checking the operating cash buffer, forecast payments and account restrictions.

Open finance skill
Review recurring business costs
Which office, sales and administrative costs should we keep, renegotiate, combine or stop?
Review recurring costs outside headcount. Combine actual usage, contract terms, overlapping services and the work that depends on each supplier before proposing savings.

Open finance skill
Check automatic expense categories
Do the rules that assign purchases to accounts still fit the records?
Compare automatic expense-category rules with historical purchases. Find rules that are outdated, conflict with evidence or cover purchases that need different treatment.

Open finance skill
Match payment notices to invoices
Which customer payment notices match the payments and invoices?
A remittance notice tells you which invoices a customer intends to pay. Check exact references, payer, date and amount first. Similarity can suggest a match; partial or uncertain allocations still need review.

Open finance skill
Check profit by customer
Is the data complete enough to trust customer-level margin?
Check whether revenue and costs can be assigned consistently to customers before calculating their profitability. Include labor, materials, subcontractors and any shared-cost policy.

Open finance skill
Charts for the monthly finance review
How should finance data be visualized so an owner can make a decision quickly?
Create cash-flow, margin, working-capital and budget-comparison charts from verified tables. Working-capital charts show balances such as unpaid customer invoices and supplier bills. Keep labels and source notes clear enough for an owner to decide what to do.
Open the system →
Open finance skill
Review past expense categories
Are past expense categories consistent enough to support automation?
Review expense categories by supplier, manual changes and ambiguous purchases. Check whether purchasing patterns changed over time before proposing an automatic rule.

What open source means here
Open source does not mean open client data. We publish reusable finance tools, checks, templates, and playbooks. Client records, workpapers, credentials, communications, and private configurations remain confidential.
Every example is synthetic. Every output is a starting point for review, not accounting, tax, legal, audit, or investment advice.
Historical version: v0.2.0 ZIP and checksum. Its cash examples precede the forecast-trough and full 13-week corrections; use v0.2.1 for those examples.
One package
Install the entire finance system
The Level Open Finance download includes all 20 skills, invented examples, licenses and source notes. A router helps your AI assistant choose the right skill. The optional MCP server is a local helper program an AI assistant can call; the shipped version only returns fixed sample data and does not read or change your live books. It contains no client records or private configurations.
