Most practice-management software will happily show you forty numbers on one screen. Colour-coded gauges, tidy little sparklines, a pie chart nobody asked for. If you run a small firm, four numbers will tell you more about your health than the whole dashboard combined, and you can carry all four in your head.
Here they are, in the order they usually start hurting: what you actually earn on the work you do, how long it takes to get paid, how much unbilled value is sitting in limbo, and whether new work is coming in the door. Track these four and you will see trouble weeks before it reaches your bank balance. Here is each one, and the plain reason it matters.
1. Realization rate tells you what you really earn
Realization rate is the gap between the money you could have billed and the money you actually collected. Say a lawyer records ten hours at 300 dollars. That is 3,000 dollars of theoretical value. But two hours got written down before the invoice went out, the client negotiated another chunk off, and one bill is still unpaid. What lands in the account might be 2,100 dollars. Your realization rate is 70 percent.
This is the number that quietly decides whether your rates make sense. A firm can be busy, fully booked, and still bleeding, because a third of the recorded work never turns into money. The trap is that busyness feels like success. Realization rate is the reality check.
Warn. If your realization rate sits below 85 percent for a few months running, the problem is rarely your billing rate. It is usually scope creep, work you never recorded, or invoices that get discounted at the last minute to avoid an awkward call.
2. Days to collect reveals cash flow trouble early
You can be profitable on paper and still miss payroll. The number that catches this is days to collect, sometimes called average collection days: from the date you send an invoice to the date the cheque clears (or the e-transfer lands), how long does the average bill take?
Watch the trend, not the single figure. If your average was 32 days last quarter and it is 47 days now, cash is tightening even if revenue looks flat. That drift is the earliest honest warning you get. It shows up here long before it shows up in your account balance, which is exactly why it is worth watching.
Tip. Sort your outstanding invoices by age, not by amount. The oldest ones, not the biggest ones, are the true risk. A 900 dollar bill that is 120 days old is closer to a write-off than a 6,000 dollar bill sent last week.
3. Work in progress is money you have not banked
Work in progress, or WIP, is everything you have done but not yet invoiced: recorded time and disbursements still sitting on the matter. It is real value, and it is also the easiest money to lose. Every day it sits unbilled, it fades. Details get fuzzy, entries get questioned, and the will to bill for old work quietly evaporates.
The danger sign is not the size of your WIP. It is its age. A large pile of recent WIP is just a busy firm about to send invoices. A large pile of old WIP is money slipping through the cracks.
Recorded time is value you intend to bill. Aged work in progress is value that is quietly slipping away.
If you find months-old time still sitting unbilled, that is your cue to run a billing cycle now, not to add a reminder for later. The value only goes down from here.
4. New matters per month is your pipeline pulse
The first three numbers look backward at work already done. This one looks forward. Count how many new matters you open each month and watch the line over time. It is the simplest early indicator of whether the firm is growing, holding, or quietly shrinking.
Revenue lags. A slow month for new intake will not hurt your books for weeks, sometimes months, because you are still billing out the backlog. By the time the revenue dip arrives, the cause is old news and hard to fix. New matters per month gives you the warning while you can still do something about it, whether that is a marketing push, a call to a referral source, or just noticing that a steady stream has thinned out.
How to check without obsessing
The point of four numbers is that you do not need to live in a dashboard. Checking hourly will not change your realization rate; it will just make you anxious. A rhythm works better than constant surveillance.
| Number | How often | What you are looking for |
|---|---|---|
| Realization rate | Monthly | A trend under 85 percent |
| Days to collect | Monthly | The average creeping upward |
| Work in progress | Every two weeks | Anything aging past 60 days |
| New matters | Monthly | The line flattening or dropping |
Pull them on the same day each month, write them somewhere you will see them again, and compare against last time. That comparison is where the value lives. A single number in isolation tells you almost nothing; the direction it is moving tells you nearly everything. Good practice-management tools can surface these without a spreadsheet marathon, and A1 CMS keeps them close to the work they come from, but the discipline of looking is what actually protects the firm.
You do not need a data analyst or a wall of charts. You need four numbers, checked on a schedule, read against the month before. Realization tells you if the work pays. Days to collect tells you if the money moves. WIP tells you what you are sitting on. New matters tell you what is coming. Watch those four honestly and you will spot most trouble while it is still small enough to handle.
