How much did you do for free last week?
Hours get logged, then rounded down, then forgotten. Put in your numbers and see what never got invoiced.
Your numbers
Example numbers1 to 50. Example: 4.
What gets logged, not what you wish. Example: 28.
Average across the team. Example: 150.
Hours worked past what the retainer includes.
Example result
Unbilled work: A$1,344 a week, A$69,888 a year, 8.96 hours a week.
- Every week
- A$1,344
- Hours a week that never got invoiced
- 8.96
That’s 16.6 weeks of one person’s work a year, done for free.

Optional. We’ll send the numbers above and the project P&L sheet. A couple of short follow-up emails from Darren come after that, and every one has an unsubscribe link.

How this is worked out
Hours a week that never get invoiced= billable people × billable hours per person, per week × the share that never reaches an invoice.
Unbilled every week= those hours × your blended billable rate. A year= that × 52.
Weeks of one person’s work= unbilled hours for the year ÷ one person’s billable hours in a week.
Retainers (optional)= retainer clients × extra hours per retainer, per week × your rate, added to the total.
Worked example with the Example numbers: 4 × 28 × 8% = 8.96 hours a week. At 150 an hour that is 1,344 a week, and 69,888 a year.
The share is the number that matters, and it is a guess until you check it. Pick one project, compare the hours logged to the hours on the invoice for last week, and use that gap. Everything is in one currency and one blended rate, so nothing here is converted.
Where Handl comes in
Handl shows uninvoiced hours per project before the invoice goes out, so this number heads to zero.
Prefer a spreadsheet?
Want this per project instead of per team? The free project P&L sheet gives you hours, revenue and margin on one row each.
See it on your own projects.
Handl turns logged hours and costs into invoices and a live margin, so you are not rebuilding this in a spreadsheet every time.
Not accounting advice. This is an estimate worked out from the numbers you type in, nothing more.
