Everything you need to bill and collect

Built from unbilled work

Select the work to bill and the invoice is drafted for you, with sequential numbering, your prefix and a branded PDF.

Status that updates itself

An invoice moves from Finalized to Viewed the moment your client opens it, then to Paid. No manual updates.

Grouped by project

Client-direct lines sit on top, each project gets its own subtotal, and there is one total at the bottom.

Card payments

Clients pay from their portal through Stripe. You pay only Stripe's processing fee, with nothing added on top.

Automatic reminders

See what is overdue in an aging view, send reminders in bulk, or set rules that follow up as an invoice gets older.

Opening balances and late fees

Carry a balance from before Qatalyst into a client's account, and apply a late fee automatically.

Questions before you start

Can I create an invoice from tracked time?

Yes. Approved time, expenses and mileage for a client are listed as unbilled work, and you pull them into an invoice without retyping anything.

How do I know if a client has seen an invoice?

The invoice status changes to Viewed the moment the client opens it, and to Paid when the payment arrives.

Can clients pay invoices online?

Yes. Clients pay by card from their portal through Stripe. Qatalyst adds no fee on top of Stripe's processing fee.

Does Qatalyst chase overdue invoices?

Yes. You can send reminders in bulk from the aging view or set rules that send them automatically as an invoice gets older.
