Why THA·ONE

Revenue is vanity. Margin is truth.

THA·ONE Post-calculation shows you after every project what actually stuck – and why. So you price the next quote with data instead of gut feeling.

Effective hourly rate

Margin divided by your actual hours – the rate you genuinely earned.

Profitability light

Green, yellow or red: see at a glance whether the project paid off against your target rate.

Plain-text verdict

One sentence names the main cause: too many hours, under-invoiced, or high external costs.

Plan vs. actual

Agreed vs. invoiced, planned vs. actual hours – the gap becomes visible.

Target rate prefilled

Your fair hourly rate from the calculation is added automatically as the benchmark.

Growing history

Every project stays saved – the basis for the upcoming client cockpit.

FAQ

Good to know.

What does post-calculation do?
It answers the question “did it pay off?” for each project. From fee, hours and direct costs it computes your project margin, the effective hourly rate you really earned, a profitability traffic light and a plain-text verdict.
How much do I have to enter?
Just four required fields: project name, client, actually invoiced fee and actual hours. Rough estimates are explicitly fine – filled in under 2 minutes.
Where does the target hourly rate come from?
It is prefilled from your THA·ONE calculation (your fair hourly rate) and can be overwritten any time. Without the calculation module you simply enter it yourself.
Is this a separate module?
Yes, post-calculation is its own module from €9/month with 14 days free. Existing customers simply add it on.
