Custom Claude agents that categorize transactions, reconcile accounts and generate reports. Connects to QuickBooks, Xero, Stripe and your bank. Built side-by-side with expert AI engineers.
Bookkeeping is the kind of work AI is uniquely good at: high-volume, repetitive, rule-based with judgment calls at the edges. An AI bookkeeper categorizes the 200 transactions that come into your bank feed this month, matches them to receipts in your inbox, reconciles your accounts at the end of each week and surfaces the three items that need a human decision. Your books stay clean without anyone spending Saturday morning on them.
Modassembly's AI bookkeeper is not a feature inside accounting software, it is an autonomous Claude agent built for your specific business. It learns your vendor list, your expense categories, your reconciliation patterns and your reporting cadence. It writes back to QuickBooks, Xero, Wave or whatever you already use. And it escalates to you via WhatsApp, SMS, email, Slack, Teams or Telegram only when something needs your judgment.
Reads your bank feed and payment processors. Categorizes each transaction by vendor, type and rule. Learns your conventions as you correct it.
Reconciles your accounts on the cadence you set. Matches transactions to receipts, flags discrepancies, closes the books cleanly each period.
P&L, balance sheet, cash flow, AR aging, vendor spend. Ask in plain language; receive a real report pulled from your live data.
Surfaces unusual transactions, duplicate charges, missed invoices and patterns that do not fit your baseline. Catches issues before they grow.
Your AI bookkeeper plugs into your existing accounting stack rather than replacing it. Common integrations include QuickBooks Online, Xero, Wave, FreshBooks, Sage, Stripe, Square, PayPal, Plaid bank feeds, Shopify, Amazon Seller Central and Gusto. Built with an expert AI engineer in your group chat, the integrations get architected live and the agent learns your specific categorization rules during onboarding.
Reconcile Stripe, PayPal and platform payouts against bank deposits. Match returns and refunds. Surface inventory cost-of-goods anomalies. Generate the monthly P&L without you opening QuickBooks.
Track project profitability, reconcile client invoices and payments, manage AR aging and follow up automatically on overdue invoices. Your AI agent chases for you so you don't have to.
Reconcile POS, delivery platforms (DoorDash, Uber Eats) and processor payouts. Track food cost percentage and labor cost as a share of revenue. Catch theft, discount abuse and pricing errors before they compound.
Categorize business expenses, separate personal from business, generate tax-ready quarterly reports, surface deductible categories you might miss. Hand your CPA a clean book at tax time.
Free in cash, expensive in your time. Two to ten hours a week depending on volume, and the books are only as fresh as the last time you sat down. AI bookkeeper handles the volume continuously.
Real judgment, real availability constraints. Best for complex situations. Most customers run an AI bookkeeper alongside a human, with the AI handling volume and the human handling judgment work and audit-grade review.
QuickBooks and Xero ship limited AI categorization features. Useful for simple cases, brittle on the edges. Modassembly is a full autonomous agent built around your business, not a categorization heuristic.
“We cross-reference food supply lists with our inventory to build cost-benefit analyses for clients. This task used to take me 2-3 days. With AI, I can do it in 2 hours.”

An AI bookkeeper is an autonomous Claude agent that does the work a human bookkeeper does: categorizes transactions, reconciles accounts, generates financial reports, flags anomalies and prepares filings. Unlike accounting software with a few AI features, an AI bookkeeper actually reads your bank feeds, payment processors and accounting platform live, makes decisions and only escalates to you when something needs your judgment.
Your AI bookkeeper connects to your accounting platform (QuickBooks, Xero, Wave, FreshBooks), your bank feeds and your payment processors (Stripe, Square, PayPal). It categorizes transactions as they come in, matches receipts to expenses, reconciles accounts on a schedule and surfaces anything that does not fit a pattern. You review the exceptions; the agent handles the volume.
Accounting software is a database with forms. AI bookkeeping is an autonomous worker that uses your accounting software (and everything else) on your behalf. QuickBooks does not categorize a new vendor for you, the human bookkeeper does. The AI bookkeeper does that work and writes the result back to QuickBooks. The software becomes a system of record; the agent becomes the workforce on top.
You build it side-by-side with an expert AI engineer inside a WhatsApp, SMS, Telegram, Slack or Teams group. We architect your custom Claude agent with you live, write the integrations with your accounting platform, bank feeds and payment processors, configure your categorization rules and reconciliation cadence, and ship it with 1-click deployment. Don't want to build it yourself? Our team designs, builds and deploys your AI bookkeeper end to end.
Common integrations include QuickBooks Online, Xero, Wave, FreshBooks, Sage, Stripe, Square, PayPal, Plaid (bank feeds), Shopify, Amazon Seller Central, Gusto, and custom internal systems. Built with an expert AI engineer in your group chat, the integrations get architected with you live. For Custom AI Fleet plans, our team handles the integration layer end to end, including authentication, permissioning and auditability.
It depends on your business. For small operations with straightforward bookkeeping (categorization, reconciliation, monthly reports), an AI bookkeeper can handle the full job. For larger operations or complex situations (multi-entity, multi-currency, tax filings, audit prep), most customers run the AI bookkeeper as a workforce on top of their human bookkeeper, so the human focuses on judgment work and the AI handles the volume.
Yes. Modassembly does not sell, share or train on your financial data. Your AI bookkeeper runs in a managed environment with scoped access to your accounting and banking integrations through OAuth and read-scoped API keys. You control what data is stored and for how long. For Custom AI Fleet plans we can further scope data access and align with compliance frameworks.
See the pricing section above for current plans. Vertical AI Employee starts at $35/month and includes 1 AI Admin plus 1 dedicated AI Employee (your AI Bookkeeper), 1-click deployment and AI Engineer on-demand for building together. AI Workforce adds 3 more AI Employees (pair the bookkeeper with sales, marketing, customer service agents). Every plan includes a 14-day free trial.
It can prepare the documents your accountant needs (categorized P&L, balance sheet, tax-ready reports, 1099 lists) and surface anything that looks off before tax season. We do not file taxes for you (that is your CPA's job) but we make your CPA's job much faster and cheaper by handing over a clean book.
