A practical benchmark for small UK accountancy and law practices measuring the hidden cost of six-vendor stacks: software subscriptions, renewal drag, owner admin time and pressure to hire before the practice is ready.
Vendor sprawl is the point where a small practice runs core operations through too many separate systems: practice management, accounts, AML or CDD, payroll or time recording, phones, portals and support. The visible cost is monthly subscriptions. The hidden cost is owner time spent chasing renewals, reconciling gaps and explaining the same client issue to different vendors.
These ranges are planning estimates for small UK practices. The exact numbers should be replaced with the practice's own invoices during a 20-minute review.
| Layer | Planning range | What it usually covers |
|---|---|---|
| Bookkeeping or accounts software | GBP 60-90/mo | Core ledger, bookkeeping, VAT or accounts production workflow. |
| Practice or matter management | GBP 80-150/mo | Jobs, clients, matters, deadlines and owner visibility. |
| AML/CDD tooling | GBP 35-75/mo | ID checks, risk evidence, audit trail and renewal prompts. |
| Payroll or time recording | GBP 25-80/mo | Payroll runs, staff workflows, time capture or chargeable work. |
| Cloud phone and communications | GBP 45-90/mo | Calls, call routing, client messages and follow-up visibility. |
| Portal or document exchange | GBP 30-70/mo | Client uploads, approvals, secure messages and document requests. |
Count monthly software spend, contract renewal dates, duplicate data entry, unresolved support loops, weekly owner admin hours and the next hire being considered. The key output is not a cheaper-software claim; it is whether the stack is creating enough avoidable work to justify a managed operating foundation.
PracticeBase uses the benchmark during the practice review. The team maps the current stack, identifies what can be consolidated, estimates recovered owner time and compares the annual platform cost against a realistic junior-hire cost.
