Software for professional services firms that stops revenue leaking away.

Software for professional services firms is custom or specialised software built to run a firm whose product is billable time and expertise — a law firm, accounting or advisory practice, consultancy, agency, or architecture and engineering firm. It typically spans professional services automation (PSA), practice or matter management, time capture and billing, resourcing and capacity planning, client portals, and profitability reporting, connecting the whole path from winning work to getting paid.

The part that decides success is usually whether the software closes the gap between the work a firm does and the work it actually bills. Firms sell time, and independent studies put revenue leakage at around 10 to 20 percent of billable work — lost to hours logged late, scope creep never turned into a change order, and slow or inaccurate invoicing. Avaib has delivered software across more than 600 projects since 2004, including systems that manage clients, engagements, time and billing, so the way a professional firm makes and records money is understood before the build starts.

By closing the specific gaps where money leaks, in the order they cost you the most. Unbilled time is the biggest, so time is captured at the point of work, coded and rated automatically. Scope creep is next, so change requests are raised and approved inside the workflow instead of agreed in a hallway and forgotten. Rate-card drift is handled by applying one controlled rate card automatically by client, role and engagement type.

Then it makes the remaining leaks visible: budget-versus-actual live on every engagement so fixed-fee overruns surface early, and accurate itemised invoices generated straight from captured time so bills go out fast and get queried less. The result is that the work your firm does and the work it bills finally match.

Yes, and it is usually the most valuable part of the build. The gap between a CRM, a project tool, a timesheet app and an accounting package is exactly where jobs and hours fall through. So integration is where we put our senior people first — connecting your delivery, time, billing and accounting so a client and an engagement are one record everywhere, entered once and consistent end to end.

Where you already run tools that work well, we integrate them rather than replace them. Where the gaps are too wide, we build the connected platform. Either way the goal is the same: no client, hour or invoice falling into the space between systems that do not talk.

Because a packaged practice management or PSA product assumes one way of running a firm — often an American one — and your engagement types, workflow, rate structure, trust or fee rules and reporting do not fit it. Fee-earners end up working around the product in spreadsheets, and the parts that matter for your firm are missing or awkward, so you pay for a platform and use a fraction of it.

The deeper issue is that off-the-shelf tools are built to be broadly acceptable, not to fit your firm precisely — and in professional services, the details of how you capture time, apply rates and bill are where the money is. Custom software is built around exactly those details, so it fits how your firm really earns instead of forcing your firm to fit the software.

Confidentiality is designed in from the start, because you hold privileged and sensitive client information. That means role-based access so each person sees only what they should, audit trails of who accessed what, and data handling built to meet your professional and regulatory obligations — rather than a third-party product holding your clients’ records under its own terms.

Because you own the platform and the data outright, your clients’ information is never locked inside someone else’s system or subject to a vendor’s changing policies. You keep control of where the data lives, who can reach it and how long it is kept — which for a professional firm is not a nice-to-have but a duty.

That is the question that decides whether the software works, so we design for it deliberately. Time capture is built to take seconds at the point of work — on a phone, pre-filled from calendars and activity — so recording an hour is genuinely easier than skipping it. When capturing time is frictionless, fee-earners stop leaving it to Friday and the billable record stays complete.

The same goes for the rest of the workflow: raising a change order, approving work, checking capacity. If any of it is painful, people route around it and the data goes stale. We make the everyday actions fast and obvious, because a system your fee-earners actually use is the only kind that closes the leak.

It depends on how much of your firm a packaged product genuinely covers. For a small or standard practice, a mainstream PSA or practice management tool may fit well enough. For a firm with a specific delivery model, unusual rate or fee structure, strict confidentiality needs, or a poor experience that keeps fee-earners in spreadsheets, off-the-shelf tools rarely fit — which shows up as low adoption, double entry and leaked revenue.

Where a product almost fits, the smart move is often to extend and integrate it rather than replace it. Where the gap is too wide, custom software gives you a platform that matches how you really earn and bill, without paying every year for a product you use a fraction of. We help you decide honestly which route fits your firm and your budget.

Yes, completely. You own the code, the data and the integrations throughout, so the platform you paid for, and the confidential client records inside it, are yours to run, extend or move to another team whenever you choose.

Our work is backed by a 30-day warranty and ongoing support if you want it, but you are never locked in and there is no per-seat price climbing every year as your firm grows. The relationship continues because the software keeps earning its place in your firm, not because leaving would cost you the system your practice runs on.
