From tracked hour to paid invoice
One place for the work, the bill and the books. No onboarding calls, no setup fees.
Track
A timer, the weekly grid, the desktop app, a Jira issue, or your own AI assistant. However your team works.
Invoice and get paid
Build invoices from tracked time and expenses, send a link your client can pay online, and let retainers bill themselves.
Sync your books
Invoices and payments land in QuickBooks Online or Xero, matched to the right customer and account.
Bill by the month, not the hour
Hosting, maintenance, a block of support hours, the software you pass through: clients still pay to keep you on hand, even when each hour is hard to justify. Put it all on one retainer. The invoice goes out on the 1st, their saved card is charged, and Stripe pays it out to your bank.
- Describe the deal once
- Flat charges for hosting or a maintenance plan, a set number of support hours, and approved expenses at cost, all on one monthly invoice. Unused hours can roll over, and time beyond them is billed at each person's rate, a flat rate, or not at all.
- Paid without a reminder
- Your client saves a card once. Each invoice is charged when it is sent: on its own when the amount never changes, or after you review it when hours or expenses change it. A declined card is tried again after 3 and 7 days.
- They see what they are paying for
- Every retainer invoice shows the hours included that period and the hours used.
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.
Verified G2 reviewer, IT services, small business
Read on G2The 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.
Stephen H., Founder, Small business
Read on G2The 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.
