One tap to log. Ten minutes to invoice. Not ninety.

Creative freelancers — designers, developers, motion artists, writers — juggle fixed-fee work and hourly billing every day, sometimes with a monthly retainer when an (often-foreign) client prefers it. iTimeSheet captures all three in one tap, reminds you to log at the hour you choose, and gets your end-of-month invoices out in 10 minutes instead of 90.

Juggling fixed-fee, hourly and retainer

How iTimeSheet handles every billing mode.

Hourly: rate cascade

Set your hourly rate per client, override per mission if needed. Time entries inherit the right rate; the math runs itself. Reports show net revenue per client at any time.

Fixed-fee: hours vs budget

Create the mission with a fixed fee. Track hours against it. The day the actual cost crosses the bid, iTimeSheet shows it — you know whether you're profitable or learning a lesson.

Retainer: monthly cap

The "X hours per month" retainer is a fixed-fee mission with a monthly reset. Run reports per month and see whether you're under or over the cap before you commit to extra work.

Switch projects with one tap

Urgent email from a retainer client, sprint for a fixed-fee project, pure dev on hourly for a third — iTimeSheet saves the running entry and starts the new one with one tap, no 3-level menu.

Workflow

A freelance day, viewed from the app.

Morning — focus on the fixed-fee deliverable

Start the timer on the fixed-fee project. Notifications quiet. A quick glance at the Today screen confirms the timer is running.

Afternoon — retainer + hourly switches

Email from the retainer client → switch project, address it, log 30 min. Then a 2-hour hourly call with a third client. Three projects, no entry lost.

End of month — invoice in 10 minutes

Pro: expenses with photos included. Studio: PDF invoice straight from the app. Report by client → hours, money, invoice — done before lunch.

How much it costs

Less than an hour of your time per year.

The Pro tier at $49.99/yr unlocks receipt photos — the right fit for freelancers who invoice through a client or a platform. At a $65/h rate, that's ~46 minutes of billable time. For self-invoicing freelancers, Studio at $79.99/yr adds PDF invoices (text-only header). Compare with $9–$25/mo from SaaS competitors that host your data on their servers.
