Late-payment enforcement
Turn on Kwill’s escalation ladder for overdue invoices: grace periods, how far it may advance on its own, the fees and interest each rung adds, and how to pause it.
Documents & payments
Create and send an invoice in Kwill, take card and local payment methods through Stripe, chase late payers with automatic reminders, and set up recurring invoices.
In the portal: Invoices › New invoice
You can also start an invoice from a project’s logged time (Independent and above), or from a signed proposal that the Invoices page lists as ready to bill. AI line items are available too, but generating them replaces your existing lines and note.
When an invoice is paid, you get a "Payment received" email, the client gets a receipt, the PDF is stamped PAID, any files gated behind the invoice unlock, and any "Invoice paid" automations run.
On every plan, Kwill emails the client a friendly reminder 3 days after the due date and a firmer one at 7 days. Each goes out once per invoice, both are on by default, and only Studio and above can switch them off. Reminders stop for archived clients.
For a structured escalation ladder with late fees and interest, see late-payment enforcement.
On Studio and above, switch on "Repeat this invoice" when creating it and choose Monthly or Quarterly. Once that invoice is paid and its due date has passed, Kwill drafts the next one and emails you to review and send it.
Nothing is sent to the client until you send it. If an invoice in the series is not paid, no further invoices are created. Repeating can only be set when an invoice is first created.
