What’s new
Release notes for Kontain.
Open a client to see their details, then edit if you need to. Billing fields go on invoices; phone and notes stay private.
Public contact is now support@kontain.net. Legal notice updated. We aim to reply within one business day; billing and invoice problems are treated first.
Kontain is available
Kontain is a lightweight CRM and invoicing tool for independent consultants, freelancers, and solo founders. Keep clients, notes, and billing in one place. Create an invoice, share a public link, and the client can view, comment, and pay by card — no account required. Download a branded PDF with your logo. The dashboard shows outstanding, overdue, and paid at a glance. Optional AI helpers tighten invoice wording and summarize private notes; you review before anything is saved. Export a ZIP of your data anytime. 14-day full trial, then Starter or Pro.
