Lock-up in professional firms: turning time into cash sooner

Work in progress and unpaid bills together make up lock-up: cash a firm has earned but cannot spend. Bringing it down is often the fastest way to fund growth.

Insight2 min readShare

In a consultancy, law firm, agency or practice, the product is time. Until that time is billed and paid, it is cash tied up in the business. Lock-up, the sum of work in progress days and debtor days, measures how long that takes. Many firms carry well over 100 days.

From work to cash

  1. RecordTime recorded daily, against the right matter or project.
  2. BillInvoices raised monthly or at milestones, not at the end of the job.
  3. CollectReminders on a schedule, with a partner or director responsible for each client.
  4. ReviewLock-up reported monthly, by client and by fee earner.

Quick wins

  • Agree billing points and payment terms in every engagement letter.
  • Take money on account for new clients or one-off work.
  • Bill disbursements as they are incurred.
  • Review old work in progress monthly and either bill it or write it off.

Recording time also matters for tax and accounts: work in progress at the year end is part of a firm’s profit, and valuing it consistently avoids surprises.
