Legal Spend Management: Budgets and Invoice Checks

What Legal Spend Management Controls

Legal spend management controls what the organisation authorises, incurs and expects to spend across its matters. A law firm’s time recording and fee collection provide supplier information. The client department must connect that information to its own instructions, approval authority and budget.

The Corporate Legal Operations Consortium’s financial-management guidance connects budgeting with accruals, forecasting, accurate billing and communication with Finance. Give each matter an accountable lawyer and assign Finance the reconciliation of costs to its accounting records. The broader legal operations model determines who performs those roles.

Use a common reporting period and tax basis before adding figures together. The useful result is a forecast whose material amounts can be followed back to the supplier and work they represent.

Build a Matter and Supplier Spend Baseline

Build the baseline from approved matters and supplier instructions before aggregating invoices. Record the matter identifier, responsible lawyer, supplier legal entity, engagement reference and approved budget. Add the fee arrangement and the person authorised to approve changes.

Separate professional fees from disbursements and specialist analysis. Counsel may charge by time, while a specialist quotes a defined package. Keep those units visible. Agreed rates and billing fields come from the engagement and any outside counsel guidelines.

Match the engagement to the purchase order, invoices, credit notes and payment references. A purchase order records purchasing authority within the organisation’s process. A bank payment supports a cash movement. Neither establishes that the billed work matched the instruction or that the responsible lawyer accepted it.

Agree the treatment of goods and services tax (GST) with Finance. Record the tax amount separately from the underlying charge and flag uncertain treatment for resolution. Apply the same reporting basis to the budget and forecast. Do not assume every supplier or disbursement has identical tax treatment.

Separate Commitments, Accruals and Paid Costs

Keep unperformed work, unbilled completed work, invoices and payments in separate states. AASB 137 paragraph 11 distinguishes trade payables from accruals for services received but not yet paid, invoiced or formally agreed. Finance determines the organisation’s accounting entries. The management schedule must identify which work each amount covers.

For the schedule below, “remaining work” means work not yet performed. It includes authorised work and any separately identified estimate needed to finish the matter. An “unbilled estimate” means completed work awaiting its invoice. Payments settle invoices and do not add another cost to the forecast.

A Fictional Investigation Reconciliation

Assume one financial investigation has an approved budget of $30,000 excluding GST for the whole matter. The reporting snapshot is the end of its first reporting period. All figures below exclude GST, and there are no deposits or credits initially.

Outside counsel’s approved estimate is $24,000. Counsel confirms $10,000 of work is complete, with $6,000 invoiced and $4,000 unbilled. The remaining work estimate is $14,000. A separate specialist’s fixed $6,000 analysis package is complete and accepted but not yet invoiced. Its fixed charge is fictional and is not a FinTrace quote.

Costs by Supplier at the Reporting Snapshot

Supplier	Invoiced	Completed, unbilled	Remaining work	Whole-matter forecast
Outside counsel	$6,000	$4,000	$14,000	$24,000
Specialist	$0	$6,000	$0	$6,000
Total	$6,000	$10,000	$14,000	$30,000

Assume Finance has paid $5,000 against counsel’s invoice. The unpaid invoice balance is $1,000, but the whole-matter forecast remains $30,000. Adding the $5,000 payment to that forecast would count the same work twice.

When the specialist’s $6,000 invoice arrives, replace its matching $6,000 unbilled estimate. Invoiced costs become $12,000 and unbilled costs become $4,000. The $14,000 remaining-work estimate stays unchanged, so the forecast remains $30,000.

If the supplier’s work estimate is uncertain, request its period-specific confirmation. The matter lawyer assesses what has been delivered, and Finance reconciles the agreed estimate to its accrual process. Preserve the original assumption and correction instead of silently replacing the earlier figure.

Review Invoices Against Scope and Accepted Work

Review each invoice against the instruction and delivered work before an authorised person approves payment. Use these checks in order:

1. Match the supplier legal entity and invoice number to the matter and purchasing record.
2. Compare rates, hours or fixed charges with the agreed fee arrangement.
3. Match the work period and description to the service received. Identify any matching unbilled estimate that the invoice replaces.
4. Check additional work against its approval, including changed document volumes or extra accounts.
5. Match disbursements to their support and review tax fields with Finance.
6. Search for duplicate charges across invoice numbers, periods and work packages, including credits and revised invoices.

For a bank-statement analysis charge, trace the quote to the agreed accounts and source coverage. Match delivery to the returned spreadsheet and cited findings report. Record the legal reviewer’s acceptance against that scope. A payment reference cannot substitute for that acceptance.

FinTrace supplies a searchable Excel ledger and a findings report with PDF filename and page references. Its per-matter quotation uses a base fee plus a per-page component dependent on scope. Capture that accepted quote as the cost basis, and record any approved expansion separately. The source references give the reviewer direct access to the evidence behind the delivered findings.

For an exception, record the disputed amount, reason, accountable lawyer and next action. For example, hold an unexplained extra-account charge for scope confirmation. Route approval or dispute through the organisation’s authority rules and keep the decision with the invoice record.

Forecast the Portfolio and Explain Variances

Calculate each whole-matter forecast as net invoiced costs plus completed unbilled work plus remaining work. Net invoiced costs include valid credit notes. Keep disputed amounts visible with their treatment recorded. Reconcile the invoice and unbilled components with Finance before adding matters into the portfolio total.

Use the matter estimate from legal project management as an input. Explain why it changed. Additional statement volumes, newly identified accounts, another legal issue or delayed delivery can alter remaining work. A payment delay changes cash timing without necessarily changing the cost forecast.

Suppose counsel’s remaining work in the fictional investigation rises from $14,000 to $17,000 after an approved scope expansion. The forecast becomes $33,000, which exceeds the original budget by $3,000. Record the change approval and seek the required budget decision. Keep the original budget visible until an authorised revision occurs.

A concise portfolio report can use one row per matter and supplier. Show the budget, forecast, variance, estimate basis, responsible lawyer and unresolved exception. Use a matter identifier and a limited work description where privileged detail is unnecessary. Any selected legal department software must preserve those records and the approval history.

A lower remaining-work estimate is a forecast reduction. Report a realised saving only against a defined, comparable baseline once the relevant cost outcome is established.

Verify the Close and Improve the Next Instruction

Close the reporting period when the budget, invoices, remaining forecast and exceptions describe the same scope and period. Confirm that each received invoice replaces the corresponding unbilled amount. Reconcile credits against their original charges and match payments to the invoices they settle.

If the forecast rises while payments stay flat, inspect completed unbilled work and approved scope changes first. If two charges appear to duplicate each other, compare the supplier, work period and package before deciding which record needs correction.

For the fictional investigation after the specialist invoice arrives, the check is $12,000 invoiced plus $4,000 unbilled plus $14,000 remaining work. That equals the $30,000 forecast and original budget. A later valid $1,000 credit for overbilling would reduce net invoices to $11,000 and the forecast to $29,000, assuming all other work stays unchanged.

Retain the reconciliation and its unresolved exceptions with named owners. If vague work descriptions caused the exception, tighten the next billing instruction. If late estimates caused it, set a supplier confirmation deadline before the next close. The control is complete when the records reconcile and the decisions are recorded.
