Bookkeeping and project costs, run for a home builder

The builder is too small for a full-time bookkeeper, so it kept hiring and training part-time ones, and the books came out different every time. It handed the whole operation to us. We built the tool and we run the books: an AI agent codes every check and card charge to a house and a cost type, and a person approves every entry.

The review screen: eleven transactions, eight of them green, with an Approve all green button. Each row shows the agent’s proposed cost type and house, why it chose them, and how sure it is. The clip approves one, then all the green ones.

The problem

The developer buys a lot, tears down the old house, builds a new one, and sells it, acting as its own general contractor. Anywhere from two to a dozen houses are under way at once, each with its own loan and its own draws.

The business isn’t big enough for a full-time bookkeeper, so it ran on part-time ones. Each left, the next had to be found and trained, and each kept the books a little differently. Things were done inconsistently, sometimes incorrectly. Most construction cost ended up in one catch-all account with the house attached but no cost type, card charges went in as monthly journal entries, one line per charge, and checks named the house only in a handwritten memo.

The owner is a builder, not an accountant. He needs to look at a charge, say which house and what kind of cost, and get back to building.

What we built

  • Every transaction, coded. Each bank and card transaction comes in from QuickBooks, and the agent proposes the house and the cost type, with its reason and how sure it is. For a check, it reads the payee and the memo from the bank statement’s image.
  • It learns. Once a vendor has been coded the same way three times, the next one is proposed with confidence. Words in a check’s memo learn their house. Every correction teaches it, and a settings page shows what it has learned, with a way to unlearn it.
  • Green means approve. When the agent is at least 85% sure, the row is green, and one click approves every green row. The rest come to us with the question; the builder hears only the ones only he can answer.
  • Loans, the way the lender keeps them. Draws, interest and fees added to the balance, and a month-end entry that brings the books to the lender’s statement, each approved before it posts.
  • Closing a sale. When a house sells, its cost moves to cost of sale in one entry a person approves.
  • Closed years stay closed. Nothing dated on or before the books’ closing date is proposed, coded, or changed.
  • One screen for the owner. Cash in each bank account, and cost to date and loan balance for every house, read from QuickBooks as it reports them.

The books stay in QuickBooks. The tool never keeps figures of its own: every balance on the screen is QuickBooks’ own, with the time it was read.

One house’s page: cost to date, loans owed, nothing left to code, and its cost broken down by cost type, from the purchase through framing, foundation, plumbing, and the rest, with each type’s share.

What changed

The builder no longer manages a part-time employee or trains the next one. The books are kept the same way every month, coded to the house and the cost type, and the builder sees a short list of questions instead of a pile of statements.

Questions

Do you replace our CPA?
No. We keep the books current and coded. Your CPA still does the taxes and the year-end, from books they can rely on.
Does the agent post entries on its own?
No. It proposes, and a person approves every entry before it reaches the books.
Which accounting system does it work with?
QuickBooks Online, here. We connect through QuickBooks’ official connection, and the books stay there.
Is the bookkeeping only for builders?
The bookkeeping service is for builders and developers. The tool behind it, which codes transactions to projects and cost types, fits any business that tracks cost by job.

Every screen shows sample data. The company isn’t named here, and we’re glad to put you in touch: ask us for a reference.
