Fees

Three ways to sit with the ledger.

Prices below are informational. This site does not take payment. If a seat suits you, write to the house and we will send a paper invoice. Refunds, when they apply, are described on the refund page.

One sitting

Ledger Audit

£420

A written critique of up to two hundred events. You receive a marked dictionary, a list of collisions, and a suggested identity rule. No live teaching.

  • Five working-day turnaround once the export arrives
  • One follow-up letter, not a call
  • Useful before a tool migration

Half year

House Residency

£4,600

Six months of monthly critiques for a team of up to four, after at least one person has completed the studio. We sit with your production ledger as it changes.

  • Six scheduled critiques
  • Written limitations page kept current
  • Not a staff-aug analytics hire

What the numbers do not buy

No implementation sprint inside your app. No overnight dashboard rebuild. No promise that week-four retention will rise. Teaching is the product. If you need engineering hours, hire engineers.

How to proceed

Send a short note describing the app and whether you already have an SDK in production. We decline work that is only a request for “more charts.” VAT, where due, will be itemised on the invoice we send by email.
