Practice management & economics
In short: Time and cost incurred on client work that has not yet been billed.
WIP is the value of unbilled work sitting in the practice. It grows when jobs stay open, when scope creeps without a fee change, or when billing is left until a job is fully finished.
High WIP usually signals a workflow problem rather than a billing problem: jobs waiting on client records, review queues or unclear ownership.
WIP is cash you have already spent staff time on; reducing it improves cash flow without winning a single new client.

Start with the workflows that cause the most chasing, then bring leads, AML, proposals and clients into the same calm operating system.
Accounting firms run on deadlines: VAT returns, payroll, confirmation statements, accounts and Self Assessment. Recording every job as a task, with an owner and a date, is the simplest way to make sure nothing is missed.
HMRC and Companies House charge penalties for late filing. A task for every deadline, with an internal date before it, gives the team a buffer.
Recorded tasks mean work continues when someone is off sick, on leave or has left the firm.
Subtask checklists make every job follow the same steps and reviews, whoever does the work.
Filters by owner, status and deadline show at a glance what is late, what is due and who needs help.
