USE CASE
AI Bookkeeper: Replace QuickBooks, Xero, and FreshBooks
Build a finance AI team that categorizes transactions automatically, reconciles accounts, and generates reports--all from a shared workspace.
QuickBooks Online Plus: $80/month = $960/year. But you still need a bookkeeper to categorize transactions, reconcile accounts, and generate reports. Add $500-2,000/month for that. Total cost: $7,000-25,000/year.
What do you actually get? A database with forms for invoices. Some rules for auto-categorizing transactions that work 60% of the time. Bank feeds that still need manual reconciliation. Reports that require a human to interpret and act on.
What if AI agents managed your entire bookkeeping operation--categorizing transactions with context, reconciling accounts automatically, and proactively flagging issues before they become problems?
The Accounting Software Tax
Here's what accounting software costs for a small business (before you even hire a bookkeeper):
| Tool | Price/Month | Annual Cost |
|---|---|---|
 QuickBooks | $80 | $960 |
 Xero | $78 | $936 |
 FreshBooks | $55 | $660 |
 Wave | $0* | $0* |
*Wave is free but monetizes through payments and payroll fees. Prices as of December 2025.
You're paying for software that still requires a human to do the actual bookkeeping. The AI does both.
What Accounting Software Actually Is
Strip away the branding and what are you left with?
| Accounting Feature | What It Really Is |
|---|---|
| Chart of Accounts | A list of categories in a spreadsheet |
| Transaction Categorization | Pattern matching against rules |
| Bank Reconciliation | Matching two lists of transactions |
| Financial Reports | Sum and group by date range |
| Invoice Generation | Template with variable fields |
QuickBooks is an $80/month spreadsheet with better formatting.
What an AI Bookkeeper Actually Does
An AI bookkeeper isn't just a chatbot that answers questions about your finances. It's a persistent agent that actively manages your books--and works alongside other agents in your finance team:
Categorizes transactions with context
Reconciles accounts automatically
Tracks receivables and payables
Generates financial reports on demand
Prepares for tax season automatically
A Day in the Life: Your Finance AI Team

The Killer Feature: A Shared Workspace
Here's what makes this fundamentally different from any accounting software you've used before. In Lazarus, your AI agents share a persistent workspace--the same files, the same context, the same source of truth.
When your bookkeeping agent categorizes a transaction, it writes to the shared ledger. Your accounts receivable agent reads from the same ledger to track outstanding invoices. Your tax agent monitors deductible expenses across all transactions. No sync issues, no API traversal--just agents collaborating in real time.

Agents collaborate seamlessly
Intelligence compounds over time
This isn't a tool that helps you do bookkeeping. It's a bookkeeper that does bookkeeping.
Build Your Finance AI Team in 15 Minutes
Here's how to build your first bookkeeping agent--and set up the shared workspace for your entire finance team:
Step 1: Create the agent and write instructions
Open Lazarus and create a new agent. Name it 'Bookkeeper' or 'Finance Agent.' Then describe what you want:
"You are my bookkeeper. Categorize all transactions in /finance/ledger/. Reconcile bank transactions daily. Flag anything unusual. Generate weekly cash flow reports. Coordinate with Tax Agent for deductible expense tracking."
Step 2: Connect your bank via Plaid
Add your bank connection. The agent will pull transactions automatically and categorize them based on your business context and historical patterns.
Step 3: Set up the shared workspace
Create the folder structure your finance team will share: /finance/ledger/, /finance/receivables/, /finance/payables/, /finance/reports/. All your agents will read from and write to this same structure.
Step 4: Import historical data
Export your existing transactions from QuickBooks/Xero as CSV and upload. The agent will learn your categorization patterns from historical data.
Step 5: Test and add more agents
Send a few test transactions. Watch the agent categorize them. Then create your AR Agent, AP Agent, and Tax Agent--all working in the same workspace.
That's it. You've built the foundation for a finance operations team that never makes errors, never forgets, and costs a fraction of per-seat software.
The Full Picture: Your Finance AI Team
Build a team of specialized agents that share the same workspace--reading each other's files, building on each other's work, and collaborating without human orchestration:
| Agent | Role | Workspace Access |
|---|---|---|
| Bookkeeper Agent | Transaction categorization & reconciliation | Writes /ledger/*, reads all |
| AR Agent | Invoice & receivables tracking | Writes /receivables/*, reads /ledger/* |
| AP Agent | Bill & payables management | Writes /payables/*, reads /ledger/* |
| Tax Agent | Tax prep & deduction tracking | Reads all, writes /tax/* |
How They Work Together
Bookkeeper Agent categorizes a transaction as "Software/SaaS" -> writes to /ledger/transactions.csv
Tax Agent reads the transaction -> flags as deductible business expense -> updates /tax/deductible-expenses.csv
AP Agent monitors the bill -> schedules payment based on cash flow -> coordinates with Bookkeeper on timing
All agents contribute to monthly close -> complete reconciliation without human intervention
No handoff meetings. No lost receipts. No "I didn't see that transaction." Every agent sees everything.
Four agents. One workspace. Zero errors. Complete financial visibility.
Stop paying for software that still requires a human bookkeeper.
QuickBooks + bookkeeper costs $10,000+/year. Your finance AI team costs a fraction of that--and actually does the work together.
