A new client should mean new revenue. But at many professional services firms, that revenue starts leaking out before anyone bills.
The client isn’t the problem. The problem is the delay between the first conversation and the signed agreement. Every day a contract sits in review, or an onboarding form sits on someone’s desk, or a KYC checklist gets buried in an inbox, that’s lost money. You won’t see it on a revenue report, but it’s real.
What’s the cost you can measure?
Start with the easiest number: the cost of a late start. A 2023 Thomson Reuters report on law firms found that small and midsize firms take 11 business days, on average, to go from first contact to signed engagement letter. Take a firm that bills $300 an hour and expects a new matter to bring in 40 hours in the first month. A five-day delay pushes $6,000 into the next billing cycle. If the matter gets rushed later, that money might never show up.
Multiply that across 24 new matters a year. That’s $144,000 in billings that either got delayed or disappeared. For a 15-attorney firm running at 60 percent realization, that’s about the same as losing one full-time attorney’s worth of revenue every year.
The math works the same way at advisory and CPA firms. A stalled consulting engagement pushes invoicing into the next quarter. A tax client who waits to sign until mid-March leaves the firm less time to do the work. Rushed deadlines mean more mistakes and write-downs.
What’s the higher cost of rushed work?
Slow intake creates a second cost, and it can be worse than the first one. When a project gets squeezed, the firm doesn’t just do less work – it does the same work faster, with more stress, more overtime, and more mistakes.
The 2022 Legal Trends Report from Clio found that lawyers write off 11% of their billable time, on average. That number gets worse when a deadline crunch traces back to a slow start. Picture a 12-attorney practice that writes off an extra 3% on matters that started late. On $2.4 million in yearly billings, that’s $72,000 lost every year, just because things started slow.
CPA firms see the same thing during tax season. When engagement letters get signed in February instead of December, staff end up working longer hours in March and April. The Rosenberg Survey, a well-known study of CPA firm finances, keeps finding the same pattern: firms with longer, more stretched-out busy seasons write off more money and pay their partners less than firms that spread the work out evenly.
What does a partner’s time cost?
There’s a third cost too: the time spent chasing signatures, sending reminders, and checking on paperwork. At many small firms, a partner or senior manager personally reviews every engagement letter, conflict check, and onboarding form. If that takes 20 minutes per new client, and the firm brings on 36 clients a year, that’s 12 hours a year spent just managing paperwork.
At $400 an hour, that’s $4,800 in lost value every year. And that assumes the partner would’ve spent that time billing clients instead, which isn’t always true. It also doesn’t count the time associates, paralegals, and admin staff spend forwarding emails, rescanning signature pages, and updating records.
The real cost isn’t the time itself. It’s the interruption. Every time a partner stops to approve a document, it breaks their focus. Research from the University of California, Irvine found it takes about 23 minutes to get back into deep work after an interruption like that. Add that up over a year, and it really drags.
How do you find your real number?
What’s this costing your firm? Track three things for 90 days:
-
- How many days pass between the first conversation and the signed agreement
- How many matters start late because of intake delays
- How many hours partners and senior managers spend chasing paperwork.
Plug in your billing rate, your realization rate, and your average matter revenue. For a 20-person advisory firm, these three costs can add up to more than $200,000 a year.
Here’s the good news – you can fix it. Intake is one of the few places in a firm where you can win back real money without hiring anyone new or changing how you do the work.
If you’ve never measured this cost, start small. Run a 30-day audit. Track every engagement letter, onboarding form, and KYC checklist from start to signature. The numbers will tell you if this is a small annoyance or a six-figure problem.
