Questions
Time tracking FAQ
Is this time tracking software free?
Your Invoice Studio account is free, and you can try the timer on this page without signing up. Saving time, timesheets, budgets and team approvals come with the Pro plan ($29 a month) and Business ($49 a month). It is one flat price, not a fee per person.
How do I turn tracked hours into an invoice?
Open Unbilled time, pick the client and the entries, and choose a rounding rule, for example up to the next 15 minutes. Invoice Studio builds the invoice with each task, its hours and your rate. Those hours are then marked as billed, so nothing is billed twice. Your original entries are never changed.
Can I track time on my phone?
Yes. The phone timer page has a big start and stop button. Add it to your home screen and it opens like an app. Time you track on your phone shows up on your computer straight away.
What if I forget to stop the timer?
Idle detection notices when you have been away and asks what to do with that time: keep it or drop it. You can also edit any entry later in the day, week or calendar view.
Can my team submit timesheets for approval?
Yes. Each person submits their week. You approve it, or send it back with a note. Reports then show hours by person and how much of their time was billable (utilisation).
Can I set different hourly rates and project budgets?
Yes. Set a billable rate per client, project or person, and mark any entry as billable or not. Give each project a budget in hours or money, watch the progress bar, and get a warning before you go over.
Can I sell prepaid hours or a monthly retainer?
Yes. Add a block of prepaid hours for a client. Every time entry draws it down, and you always see how many hours are left. You can also share a private report link so the client sees the hours, with no login.
Does it work in Bangladesh and with my currency?
Yes. Invoice Studio works in any country. Bill in taka, rupees, dollars, pounds or euros, and add your own payment details such as bKash or a bank account to the invoice. Reports export to CSV for payroll or Excel.
