Legal Billing vs Legal Accounting: What UK Law Firms Need to Check
Time recording and invoices are important elements of practice operations, but billing functionality does not establish that a software product provides a complete legal accounting system. Law firms should assess each capability separately.
Legal billing and legal accounting are related, but they are not the same. A system that records time, expenses, work in progress and invoices is not automatically a complete regulated accounting solution. UK firms should evaluate the distinction before purchasing software or moving financial processes.
Key distinctions
- Operational billing versus bookkeeping
- Client money versus office money
- Reconciliation
- Audit trail
- Financial reporting
- Regulated duties
- Evidence of actual integration capabilities
Time recording and work in progress
Time recording captures work undertaken on a matter. Work in progress (WIP) represents recorded work that has not yet been billed under the firm’s applicable processes. A good operational workflow lets authorised users review time, expenses, rates and matter context.
Billing and invoicing
Billing workflows may create invoices, record adjustments, write-offs or partial payments, and present outstanding balances. These are valuable operational capabilities, but they do not necessarily perform ledger maintenance, bank reconciliation or statutory accounting functions.
Legal accounting and client money
Accounting systems maintain financial records and controls. Where a law firm holds or handles client money, its obligations may include specific recordkeeping, reconciliation, authorisation and reporting requirements. The scope depends on the applicable regulatory framework and the firm’s operations.
For firms regulated by the Solicitors Regulation Authority in England and Wales, the SRA Accounts Rules set out client money requirements, including rules on keeping client money separate (rule 4) and on records and reconciliations (rule 8). Firms in Scotland and Northern Ireland are subject to different regulators and rules.
Questions to ask a vendor
- Does this system issue and track invoices, or does it also maintain a complete general ledger?
- How are client money and office money separated and reconciled?
- Are financial events logged with appropriate permissions and auditability?
- Which accounting integrations are supported and tested, not merely planned?
- How are currency handling, partial payments, credits and write-offs managed?
- What independent evidence supports any compliance or certification claim?
A safer procurement approach
Document the firm’s required accounting controls and compare them with the vendor’s proven functionality. Where necessary, retain a dedicated accounting system and define the integration and reconciliation responsibilities clearly before launch.
Where Legify fits
Legify’s demonstration environment includes time and expense recording and operational billing workflows. It is not currently claimed to be a complete, independently verified legal accounting or SRA Accounts Rules compliance solution.
