From tracked hour to paid invoice

One place for the work, the bill and the books. No onboarding calls, no setup fees.

Step 1

Track

A timer, the weekly grid, the desktop app, a Jira issue, or your own AI assistant. However your team works.

Step 2

Invoice and get paid

Build invoices from tracked time and expenses, send a link your client can pay online, and let retainers bill themselves.

Step 3

Sync your books

Invoices and payments land in QuickBooks Online or Xero, matched to the right customer and account.

Firms that bill with Quanta

  • I run a service-based IT consulting firm and Quanta is an excellent time-tracking tool for my team, projects and workflows. The integrations are top-notch and more importantly, the team listens to our feedback and is supportive as well as honest about their pricing.

  • The pricing is clear, straightforward and very reasonable. … Quanta integrates perfectly with Xero (our accounting package) for invoicing, which was one of the key requirements we had.

  • The interface is a joy to navigate and work with. The recent addition of Stripe integration is a welcome addition to the invoicing capabilities and gives me everything I need.
