Messy books? Mylo's clean-up tool rebuilds years of expenses automatically

Connect a client's inbox, bank and cards, and Mylo backscans years of history: every receipt and invoice found, duplicates collapsed, payments matched to the cent. What's left is a short exception list instead of a clean-up project.

Every accountant knows the moment. A new client walks in and the books are eighteen months behind. Receipts live in an inbox nobody has opened, the card feed is a wall of uncategorized transactions, and the same invoice seems to exist in four places. The traditional answer is a clean-up engagement: weeks of manual archaeology, billed by the hour, dreaded by everyone.

Mylo's clean-up tool exists for exactly this moment. Connect the client's email inboxes, bank accounts and cards, and Mylo backscans years of history on its own. It rebuilds the document trail, reconciles everything that does not need a human decision, and hands you a short exception list for the few items that genuinely do.

The backscan: years of history, not ninety days

Receipts and invoices live in the inbox, so that is where Mylo goes. The backscan sweeps the full history of every connected mailbox in two passes: a fast pass that surfaces the bulk of the documents within minutes, then a complete sweep that leaves nothing unread. Each email is split into its parts, the body and every attachment judged separately, so a single message carrying five invoice PDFs becomes five invoices, and a packing slip riding along with a bill gets correctly ignored. Bank and card history is pulled in parallel, as far back as the feed allows.

Duplicates, collapsed

Here is a thing we learned from real client data: the same invoice arrives three to thirteen times. The vendor sends the original, the accounting system sends a notification, and the AP team forwards copies around. Mylo collapses all of it. Byte-identical files are dropped instantly, the same bill arriving from different sources merges into one ledger entry, and true twins are caught by a strict rule that requires the same vendor, the same document number and the exact same amount before anything is hidden. Recurring charges like installment plans are recognized as a series, never flagged as duplicates.

Reconciliation you can trust

Matching documents to payments is where clean-up tools usually get sloppy, so Mylo is deliberately strict. A match requires the exact amount to the cent, a payment date that makes sense, and the vendor names to actually correspond. An AI reviewer then checks every candidate, and a match is confirmed automatically only when the rules and the reviewer both agree. Anything plausible but uncertain is queued as a suggestion you confirm or dismiss in one click. The result is a ledger you can stand behind, not one you have to re-audit.

The exception list

When the backscan settles, what remains is the short list that genuinely needs the client: transactions with no document anywhere, documents with no matching payment, and the occasional personal-or-business question. Instead of sending a client forty questions over three months, you send one short list once.

For firms: clean-up as a product, not a chore

For accounting and bookkeeping firms this changes the economics of taking on messy clients. A clean-up engagement stops being weeks of manual work and becomes a connected-accounts setup, a backscan, and a review of the exception list. You can quote it with confidence, run it at high margin, and start the ongoing relationship with books that are already clean. Combined with Mylo's accountant workspace, one team can run clean-ups across many clients from a single view.

If you have a client whose books need rebuilding, we would love to show you the clean-up tool on their real data. Book a demo on our accountants page and bring your messiest client.
