  • Integrated time entries and expense receipts into each invoice line

Leading to faster approvals and reduced days sales outstanding via clearer client invoices.

Corporate Legal Department

Best practices for secure and accurate legal invoicing

Following consistent procedures reduces errors and strengthens compliance for invoices that require signatures, trust accounting, or multi-party approvals.

Standardize invoice structure and terminology
Adopt firm-wide invoice templates with consistent line-item descriptions, matter identifiers, and disclaimers so clients receive predictable, clear bills and internal reconciliation becomes straightforward.
Require approvals for high-value invoices
Configure approval gates for invoices above a dollar threshold or outside expected budgets to catch errors, verify fee reasonableness, and reduce write-offs or client disputes.
Retain complete audit trails
Preserve full event logs, version histories, and signer authentication records for every invoice to support compliance obligations, billing disputes, and internal audits.
Review integrations periodically
Validate mappings between practice management, accounting, and invoice systems routinely to prevent desyncs that can cause double billing or missed charges.
