You don’t have an AI problem. You have a chart-of-accounts problem

Private equity is buying AI seats. The close still slips. Not because the model is weak. Because revenue means three things, the warehouse does not join to NetSuite, and nobody owns the mapping table.

That is not an intelligence problem. It is a chart-of-accounts problem.

Ahead of the market, behind the books

Accordion and Ramp’s AI in PE work is being sold as an adoption race. Paid tools in about 59% of PE-backed companies versus 77% of venture-backed ones, from their index and the write-up. Fine. Scoreboards are not the close.

The useful bit is the boring bit. Fragmented ERPs. Inconsistent definitions. Weak governance over data and reporting. Finance cannot automate what finance cannot name. TMT can show 76% “adoption” and retail 39% and it still will not tell you whether month-end is a fact or a folklore spreadsheet.

Vendor studies like to add a 30% faster close and a 15% drop in DSO. Treat those as a brochure, not a covenant. The industrial case in the same research — forecast accuracy up, working capital down, reporting time halved — only happens if the mapping table is real and someone is allowed to kill duplicate codes. Otherwise you have Copilot on a mess, and a mess with a chatbot is still a mess.

The diligence question

I already asked whether the agent is in the ledger or beside it. I already asked whether the spend shows up as value or as a bill, and whether it changes Monday morning.

Ask this one before those. Show me the chart of accounts. Show me who owns “booking.” Show me the join between the warehouse and the GL. Show me the last time a duplicate revenue code was retired, not aliased. If the answer is a shared drive and a person who left in March, you do not have an AI programme. You have a definition debt, and the model will compound it.

PE does not buy a prompt. It buys a set of books that survive a second 100-day. Two versions of EBITDA in the pack is not a tooling gap. It is an owner gap.

Fix the names, then rent the model

Do not rip out the ERP for a logo. Lock three things. One definition of the number the board actually uses. One owner. One place the mapping lives that is not a chat. Then the agent is allowed near the close. Not before.

You do not have an AI problem. You have a chart-of-accounts problem. Solve that, or stop calling the seat transformation.
