Why Kestor
Built for invoicing, not accounting overload
Most products force you into one of two extremes: simple templates that break once your workflow gets real, or accounting platforms packed with features you never asked for. Kestor gives you the invoicing workflow end to end and stops there on purpose.
Everything billing needs
Create, send, track, follow up, and manage recurring invoices in one workflow.
Professional by default
Your clients receive invoices that look clear, credible, and ready for serious business.
Simple without being limited
You get visibility and control without taking on bookkeeping software complexity.
Who it's for
Made for people who bill clients directly.
Kestor is for independent professionals who want invoicing to stay clean, credible, and easy to manage from first draft to final payment.

How is Kestor different from FreshBooks, Wave, or other invoicing tools?
Kestor is deliberately narrower. It focuses on invoicing and receivables: creating invoices, sending them, tracking payments, following up, and handling recurring billing. It does not try to be full accounting software.
What does Kestor actually cover?
Kestor covers the billing workflow from setup to paid invoice: client records, drafting, issuing, delivery, payment tracking, reminders, and recurring invoice drafts.
Does Kestor support recurring invoices?
Yes. You can create recurring schedules for repeat work, and Kestor generates draft invoices for each cycle so you can review them before sending.
How do reminders work?
You can configure reminder timing and also send reminders manually. Automatic reminders only begin after an invoice has been sent or marked as sent.
Do my clients need an account?
No. Your clients receive a professional PDF invoice by email and pay through whatever method you've configured: bank transfer, Swish, or a custom method. No sign-ups, no friction on their end.
What payment methods does Kestor support?
Kestor is payment-method agnostic. You configure your own: bank transfer, Swish, or a custom method with your own instructions. Your payment details appear directly on each invoice. Kestor does not process payments.
Is there a free plan?
Yes. The Free plan includes up to 3 clients, up to 5 invoices, and the full core workflow: invoice creation, client management, payment tracking, reminders, and history. No credit card required.
What does Kestor Pro include?
Pro removes usage limits and adds recurring invoices, automatic payment reminders, and priority support. It's $8 per month or $79 per year.
Professional invoicing, minus the software bloat
Set up your details, create your first invoice, and keep billing, reminders, and payment tracking in one focused workflow.
