Financial Tools

Simple double-entry bookkeeping for founders. Track income, expenses, transfers, and generate P&L reports - all through conversation.

You don’t need QuickBooks to know where your money’s going. FoundersOS gives your AI a simple, clean ledger that tracks income, expenses, and account balances. Ask questions in plain English, get real answers.

See it in action: ask your AI to “run the financial tools demo” - a guided walkthrough on temporary data that cleans up after itself. More about demos.

What you can do

“Record a $5,000 payment from Acme Corp for the March retainer.”

“I just paid $200 for Figma - log that as a design expense.”

“What’s our financial summary?”

“Show me the P&L for Q1.”

Your AI handles the bookkeeping. You handle the business.

Who can see the books

Financial data is the most sensitive part of FoundersOS, so it has its own access control. By default, the owner of a FOUNDERS_OS_COMPANY_ID is the only one who can read or write financial data - everyone else on the team is locked out until explicitly granted.

"Give Sam access to the OTT books."
"Who can see our financials right now?"
"Revoke financial access for the contractor account."

Use set_financial_access to grant or revoke, and get_financial_access to check the current list. Everything else in FoundersOS - CRM, tasks, memory - stays shared across the team; only the ledger is gated.

How it works

The financial tools use a simple double-entry ledger model. Every transaction has:

A type (income or expense)
A category (you define these - “SaaS Revenue”, “Office Rent”, “Travel”, whatever fits)
An account (checking, savings, petty cash)
An amount and date
An optional description

When you record a transaction, the account balance updates atomically. No manual reconciliation. No drift.

Multiple companies

Running more than one business? Each MCP server instance is scoped to a FOUNDERS_OS_COMPANY_ID. Set up separate server entries in your config and your books stay completely separate.

"Show me the financial summary for OTT."
"Now show me the P&L for SideProject Co."

Each company has its own accounts, categories, and transaction history.

P&L reports

The get_pl_report tool generates a profit and loss summary grouped by category for any date range. Ask for it however feels natural:

"P&L for last month"
"Show me income vs expenses for Q1 2026"
"How much did we spend on marketing this year?"

Your AI interprets the date range and pulls the right data.

Example session

You: "Create categories for SaaS Revenue, 
      Consulting Revenue, Office Rent, 
      and Software Subscriptions."

AI: Done. Created 2 income categories 
    and 2 expense categories.

You: "Add a checking account with a starting 
      balance of $25,000."

AI: Created "Checking" account with 
    a $25,000 balance.

You: "Record $8,500 income from Widget Corp, 
      SaaS Revenue, into checking."

AI: Recorded. Checking balance is now $33,500.

You: "Log $299 expense for GitHub Team, 
      Software Subscriptions, from checking."

AI: Recorded. Checking balance is now $33,201.

You: "What's the P&L for this month?"

AI: Profit & Loss - April 2026
    
    Income:
      SaaS Revenue: $8,500
    
    Expenses:
      Software Subscriptions: $299
    
    Net Income: $8,201

Note: This is not accounting software. FoundersOS financial tools are designed for founders who want a quick, conversational way to track money. For complex accounting needs (payroll, taxes, multi-currency), pair it with proper accounting software. Think of this as your daily financial pulse check, not your tax filing system.
