Tristiks Grow turns your tracked hours and expenses into branded invoices, sends them on schedule and follows up with reminders, all from one place.
Track billable hours, add expenses, send invoices and collect payments in one connected workflow.
Track time in the desktop app or the web timer and every hour lands on the client's timesheet with its project and task. When you invoice, add the unbilled hours for a date range in one click and set your rate; entries already billed are locked.
Create an invoice from a client's tracked hours in a few clicks. Add taxes, payment terms and a message, in the client's currency. Your logo, business details and brand colours appear on every invoice and PDF.
Log expenses against a client as you go, or scan a receipt and let Tristiks Grow fill in the details. Unbilled expenses are ready to add when you build the client's next invoice.
Every invoice you send carries a secure link where the client can view it and download the PDF. Mark it paid in one click and see what's paid, due and overdue at a glance. Card and PayPal payments are coming soon.
Schedule an invoice to go out on a set date, or make it recurring. Turn on payment reminders to email clients 3 days before a due date, on the day, and 7, 14 or 30 days after.
