Time and invoices
Every hour worked becomes an hour billed.
Timers against tasks, signed-off timesheets, rates and rounding, retainers and fixed-price milestones – one invoice per period, each period once.
What it gives you
- so that the hours you work stop leaking
- so that the invoice is right the first time
- so that estimates get better every month
Time & invoices
From tracked hour to invoice
17:05 38.5 h + 1 retainer → invoice draft · each period once
Track against a task, sign hours off, and compare estimate with reality.
→ so that every hour worked is an hour you can bill


Compared with the usual tools
Calendar apps rarely touch money. Here tracked time, rates and retainers end up on one invoice draft, next to the estimate it can be compared with.
Brand-by-brand comparisonsWork it out with your own numbers.
Three calculators, formulas open. The price is never a list: it is a share of what this gives back to you, and the recommendation is the biggest package whose first year stays under 30% of that – so you always keep at least 70%.
