For solo U.S. bookkeepers

AI document collection for solo bookkeepers

Every client has a deadline on the 5th, the 15th, or the last day of the month — and every one of them sends a different mix of receipts, statements, and forwarded PDFs that you have to key by hand. Plumbmark is the AI-first intake layer that catches the documents, extracts the numbers, and flags the missing recurring expenses before the close ever starts.

The problem

Fifteen clients. Three deadlines. A receipt inbox that resets every Monday.

Monday morning the eighth is its own little nightmare: the bakery owner's Square payout just landed, the consultant forgot to forward her Stripe transfers again, and the SaaS founder is texting you a photo of a crumpled Uber receipt from two weeks ago. You spend three billable evenings typing numbers off of sideways phone photos, chasing the client who still hasn't sent last month's bank statement, and reconciling the same $9.99 SaaS charge you flagged last month — until you realize it didn't post this month. That's the month-end you're trying to survive, not the work you trained for.

What changes

Three things that move the needle on a solo bookkeeper's month.

Receipt & statement extraction
Drop the PDF, the phone photo of a crumpled gas receipt, or the forwarded bank statement into the intake. Plumbmark lifts the merchant, amount, date, and category into the client's transaction record — no rekeying, no eye-strain, no spreadsheeting the Square payout line by line at 10 p.m.
Anomalies flagged before month-end
A recurring subscription that didn't bill this month, a category that doesn't match the merchant, an out-of-period posting from a statement that closed last cycle — Plumbmark surfaces what would have caught you during reconciliation, so the close gets done right the first time and the variance chat with the client happens from a position of having already seen it.
Faster client onboarding
A new engagement goes from “I just signed them” to a reconciled first month in under ten minutes — opening balances chart of accounts, the last two months of statements, and the first wave of receipts landed, all in one client record. You start the close the day the client signs, not the day the paperwork finally arrives.
