Law firm billing & time automation software

Time capture, fee arrangements, and invoicing built around how your firm actually bills — owned by you, with no per-seat tax and no vendor lock-in.

01TL;DR
02The problem

Where billable time leaks before it is billed

Time recorded a week late is time half-forgotten and often written down. Most firms run a packaged billing module that assumes one rate per fee-earner, one approval step, and one invoice format — so the fixed-fee matters, the blended-rate panels, and the partner who insists on reviewing every draft all become spreadsheet exceptions handled outside the system. Each exception is a place where realised revenue quietly leaks.

Custom billing software closes those gaps because it is shaped to how your firm actually bills, not to the rate model a vendor shipped. Time is captured at the point of work, mapped to the right arrangement automatically, and routed through your real approval chain. Because you own the source, there is no per-seat tax as the firm grows and no module you cannot change.

03What we build

What a custom billing & time system covers

  • Time capture — timers, calendar and email mining, and quick narrative entry tied to the right matter, so time is recorded the day it happens.
  • Fee arrangements — hourly, fixed, blended, capped, and contingency, with your write-up and write-down rules applied automatically.
  • Pre-bill review — partner-facing draft narratives, edits, and approvals before anything reaches the client.
  • Invoicing — your invoice formats and ZATCA-compliant e-invoices for Saudi clients, posted straight to your accounting system.
  • Realisation reporting — WIP, lock-up, realisation, and aged-receivable views without an export-to-spreadsheet step.
04Build vs. operate

When to build, and when to run an operator

A billing system is a system of record — it belongs to you. But the work that surrounds it is often repetitive chasing: nudging fee-earners to enter missing time, following up on aged invoices, reconciling client trust balances. That work is frequently better run than owned, by a managed operator that acts on the data rather than another dashboard someone has to remember to open.

05How we deliver

Blueprinted, built, handed over

We start by mapping how your firm actually bills — every fee arrangement, every approval, every exception that currently lives in a spreadsheet. That blueprint becomes the spec. We build against it in milestone-gated stages you can see, and we hand over the source, the schema, and the deploy pipeline so your team or any developer can extend it.

For Saudi and GCC firms, the system is hosted in-region with Arabic-first interfaces, generates ZATCA-compliant e-invoices, and can integrate with national platforms such as Najiz where matter data drives billing.

Questions
  • Why build custom instead of using our practice suite’s billing module?

    A packaged module assumes one rate model and one workflow, pushing your fixed-fee and blended matters into spreadsheets where time leaks. Custom software is built to every fee arrangement and approval you actually use, and is owned outright — no per-seat tax, no lock-in.

  • Does it generate ZATCA-compliant invoices?

    Yes. For Saudi clients the system produces ZATCA Phase 2 (Fatoorah) compliant e-invoices with the required fields, QR codes, and reporting, mapped in the blueprint.

  • Can it post to our accounting or ERP system?

    Yes. Invoices and time can post directly to your accounting or ERP system, removing the double-keying between billing and the ledger.

  • Do we own the software?

    Yes — you receive the source code, the schema, and the deploy pipeline. Your own team or any developer can extend it. There is no vendor lock-in.

  • Can it also chase unbilled time and aged invoices?

    That chasing is often better run than owned. The same engagement can pair the custom system with a managed operator that nudges fee-earners for missing time and follows up on aged receivables — see the accounts-receivable workflow.
