Bookkeeper playbook.
An ICB / AAT-qualified London bookkeeper running monthly compliance + management accounts for 30–80 SME clients. The win is moving from hourly billing to fixed-fee monthly retainers and automating data capture so each client takes <2 hours per month.
Overview
A London bookkeeper running solo typically manages 30–55 clients at £150–£420 per client per month (£6k–£18k MRR). With one part-time junior the practice can hold 70–110 clients (£14k–£35k MRR). The single biggest economic lever is fixed-fee pricing — hourly billing caps margin at 35–45%, while fixed-fee + automation pushes it to 55–70%. The second lever is being MTD ITSA-ready by April 2026: the first 950k self-employed taxpayers (£50k+ turnover) need quarterly digital filings, and bookkeepers who lock these clients in 2025 win 5-year LTVs. This playbook covers operationalising a London bookkeeping practice — qualifications, AML supervision, software stack, pricing tiers and the month-end pipeline.
