Common questions
How does the timer work across devices?
TAV is a progressive web app. Start a timer on your phone at a client meeting, stop it on your laptop when you're back at your desk. Everything syncs instantly. The timer runs in the background while you switch apps. Install from your browser — no app store required.
Can I track time for multiple clients in one day?
Yes. Each timer session is tied to a specific client and project. Switch between clients throughout the day. TAV keeps entries separate and attributes them correctly when generating invoices. You can also log time manually if you prefer.
How do tracked hours become invoice line items?
Every timer session logs the client, duration, description, and your hourly rate. When you invoice, TAV pulls all unbilled entries for that client, converts them into line items showing date, hours, description, and amount. Review, adjust if needed, send. Entries are marked as billed so you never double-bill.
Does TAV handle retainer agreements?
Yes. Set up a recurring monthly amount for a client. TAV generates the invoice each month automatically. You can also combine retainer billing with hourly overage — fixed base plus tracked hours beyond the retainer scope.
Can I use TAV alongside my existing tools?
TAV handles the business side — proposals, contracts, time tracking, invoicing, payments. It does not replace your IDE, project management, or version control. Use TAV for the client-facing workflow and keep your dev tools as they are.
