Because the invoice is assembled by hand. Somebody exports time, matches it against the contract, decides what to write off, and types the result — for every client, every month.
The write-offs are the expensive part: decided under time pressure and absorbed into a lower total rather than recorded as write-offs.
Time is logged against the task as work happens rather than reconstructed on a Friday. Rate cards in Books price it, and the invoice is raised from delivered work against the sold lines.
Nothing is re-keyed, so the invoice and the delivery record cannot disagree about what was done.
It will not decide what to write off. It records the decision and who made it, which is what turns realisation into something manageable.
And it will not chase payment. Books holds the ageing; the conversation is still yours.
Work in progress is visible during the period rather than discovered at billing. Realisation — billed against billable — becomes a reportable number.
And margin per project is live, because cost and sold value sit on one record.
They become a view of time already logged, not a separate exercise.
Rate cards in Books, per client, currency and term.
Yes, recorded rather than absorbed.
We will run it end to end on your own numbers in half an hour, and tell you honestly which parts Treepie does not improve.
