Keep the books up to date with an AI agent
A Monmo agent can do the daily bookkeeping in Xero or QuickBooks. It matches bank lines to invoices and bills, codes expenses, attaches receipts from Gmail, drafts reminders for overdue invoices and prepares the month-end reports. It asks before it changes the books or sends an email. It does not file taxes or give accounting advice; your accountant reviews and signs off.

How the agent does it
- 01
It opens the books every morning
You agree a routine: every weekday at 7:00 the agent reads the new bank lines in Xero or QuickBooks. It uses your login through the connection, or the web version in its own browser where the connection stops.
- 02
It matches each line
Every line is compared with open invoices and bills by amount, date and reference. A Stripe payout of $4,812.40 is broken into the 37 payments and fees inside it, so each sale is matched and not just the lump.
- 03
It codes the expenses and finds the receipts
For spending with no bill, it suggests the account and tax rate from your chart of accounts and from how you coded that supplier before. It finds the receipt in Gmail and has it ready to attach.
- 04
It asks once for the day's lines
One card lists what it proposes, for example 46 of 52 lines with their match, account and tax rate. Open any line to change it, then allow the batch. The six it was unsure about come to you with a question.
- 05
It chases overdue invoices
Each Tuesday at 9:00 it lists invoices more than seven days late and drafts a reminder for each customer in Gmail, with the invoice attached. The tone is firmer at 30 days. You approve the batch before anything is sent.
- 06
It prepares the month-end pack
On the third working day it checks that each bank account agrees with its statement, lists what is still uncoded, and builds the profit and loss, aged receivables and payables, and cash position with notes on what changed.
- 07
Your accountant signs off
The pack goes to you with a list of questions for your accountant: unusual amounts, possible duplicates, items it would not code. Tax returns, year-end adjustments and advice remain with a qualified person.
What reaches you each day and at month end
- Bank lines matched and coded each morning, waiting on one approval
- A short list of the lines that need your answer, with the receipt where it was found
- Reminder emails drafted for overdue invoices, sent only after you approve
- A month-end pack: profit and loss, aged receivables and payables, cash position and notes
- A list of questions ready for your accountant
When it asks you
Reading the books needs no approval; reconciling, coding or changing a transaction does, and one card can cover the whole day's lines. Reminder emails wait for your approval too, and paying a bill is always a request of its own.
How to ask
- Every weekday at 7:00, match the new bank lines in Xero, suggest an account and tax rate for the rest, and ask me before you reconcile. Anything over $2,000 comes to me line by line.
- Each Tuesday at 9:00, draft reminders for invoices more than seven days overdue. Skip Northwind, we have agreed a payment plan with them.
- On the third working day of the month, prepare last month's pack for our accountant: P&L against the month before, aged receivables and payables, and anything you could not code.

Questions people ask
Can an AI agent do my bookkeeping?
It can do the routine part. A Monmo agent matches bank lines, codes expenses, attaches receipts, drafts payment reminders and prepares month-end reports in Xero or QuickBooks. You approve changes to the books, usually one batch a day. It does not stand in for professional judgment: your accountant reviews the result, and tax filing and advice are not part of the job.
Will the agent file my tax return?
No. The agent keeps the records in order and prepares the figures a return is built from, such as sales tax collected and paid for the period. It does not lodge returns, decide how something should be treated for tax, or give accounting advice. Those remain with your accountant or tax agent, who can use the month-end pack as a starting point.
How does it know which account to code an expense to?
It reads your chart of accounts and your history. If the last ten payments to a supplier went to Software subscriptions, the next one is proposed there too. You can add rules in plain words, such as anything from the landlord is Rent. When it is unsure it leaves the line for you with a question instead of guessing.
Does it work with Xero and QuickBooks?
Yes, with both, using the account you connect and the permissions that account has. Other ledgers in the app directory work the same way. Reading is done through the connection; where a step such as bank reconciliation is not covered, the agent can use the web version in its own browser. Stripe and Gmail connect separately for payouts and receipts.
Is it safe to let an AI agent into our accounting software?
You control what it can reach. The agent signs in with a login you choose, so give it a role with only the access bookkeeping needs. Reading needs no approval; reconciling, editing, sending and paying each do. Its screen is open to you while it works, you can take the mouse, and you can disconnect the app whenever you want.
