InvoiceKit sends your invoices, repeats the monthly ones on its own, and follows up on late payments automatically — so you don't have to write another awkward "just checking in" email.
Retainers and monthly clients are billed automatically. Set it once and next month's invoice creates itself.
Polite follow-ups go out before the due date and after it passes, on a schedule you choose.
Paid, due and overdue in one view, with totals per client. No more digging through your inbox.
Late payments are a cash-flow problem and a time problem. InvoiceKit handles both.
Remembering who is late, finding the invoice and writing the email takes time every week. Here it happens on a fixed schedule.
The reminder comes from the system, in a consistent and friendly tone. Your client relationship stays about the work.
Forgetting to send a monthly invoice means working for free. Recurring billing makes sure every retainer is invoiced.
