Law Firms Back-Office Services

How the money moves in a law firm

A law firm's cash cycle is unusual because much of the money you hold isn't yours yet. Funds come in as monies on account, sit in the trust account, and only become firm revenue once work is billed and a compliant transfer to the office account is made. That creates a rhythm no other business has: fee earners record time, an invoice is raised, trust is applied or the client is chased — and every step has a lag.

The practical consequence is lock-up — cash stuck between work done and money banked. What makes it distinctly legal is the trust dimension: a slipped billing run doesn't just delay an invoice, it delays your entitlement to money already sitting in your own trust account, because client funds can't move to the office account until a compliant bill supports the transfer. A firm can hold a healthy trust balance and still struggle to meet payroll from the office account.

The back-office job is to keep that pipeline moving: month-end billing runs that actually happen on time, trust-to-office transfers processed the moment authority exists, and a debtor follow-up cadence that doesn't rely on the billing partner remembering.

The workforce pressure points

Under the Legal Services Award 2020, the risk sits in a gap most firms never notice: the practice management system captures every six-minute unit a fee earner records, while the people the award actually covers — the support team — often have no reliable record of their hours at all.

• Unrecorded support hours. Fee-earner time is measured to the minute because it's billable; support staff time usually isn't, because it isn't. When a completion or trial runs long, there may be no timesheet showing what award-covered staff actually worked — and you can't pay entitlements correctly on hours nobody captured.
• Salaries that must still be reconciled. Paying support staff an annual salary doesn't switch the award off. If hours spike during a busy matter, the salary still has to cover what the award would have required — which means someone has to track hours and check, pay period by pay period.
• Classification creep as a systems failure. Duties evolve inside the practice — someone starts drafting rather than formatting, a supervised period ends — but payroll only knows what HR last told it. If those systems never talk, the classification a person is paid at quietly drifts away from the work they're recorded doing.

The discipline is a payroll process that applies the award to real, recorded hours every pay run. That's the core of what a people function should do for a firm.

Systems that fit the way you work

Law firms run on a practice management system — LEAP, Smokeball, Actionstep, Clio or similar — and the back office lives or dies on how cleanly it connects to the general ledger. The classic failure mode is two sources of truth: the PMS says one thing about a matter, Xero says another, and nobody reconciles them until the trust examiner or the accountant asks awkward questions.

What good looks like: time capture that fee earners actually use, disbursements coded to matters at source, the trust ledger reconciled on schedule (your state's rules set the frequency — treat it as non-negotiable), an automated path from approved bill to ledger to debtor follow-up, and matter-level reporting that shows write-offs rather than burying them. When the same team runs the books, the payroll and the systems, the reconciliation gaps between PMS and ledger stop being anyone's-guess territory — that's the case for a connected back office over three separate providers.

What changes as you grow

Sole practitioner. You are the fee earner, the billing department and the trust signatory. The back office's job is to protect your billable time: bookkeeping off your desk, billing runs that happen without you initiating them, and trust compliance kept examiner-ready year-round rather than assembled in a panic.

Employed solicitors and support staff. Leverage arrives, and the numbers that matter change shape: how many fee earners each principal carries, the rate at which supervised work goes out versus what it costs in partner review time, and whether new hires are building the firm or consuming it. The back office needs to surface those leverage numbers — alongside award payroll and supervision records — without adding another job to the supervising principal's day.

Multi-partner or multi-office. Partner drawings, profit-share arrangements, inter-office cost allocation and consolidated trust obligations across jurisdictions all land at once. The back office has to produce numbers partners trust enough to argue about — and the firm has to keep running when any one partner is on leave. If a single principal is the only trust-account signatory, or the only supervisor junior solicitors can practise under, a fortnight's holiday stalls both the cash and the matters.
