What’s in Kontain

• Clients

  Your client list, organized

  Contacts, notes, priority, and billing details in one place. Open a client for their invoices; billing goes on the PDF, phone and notes stay private.

• Invoices

  From draft to paid

  Draft, send, track status. Several lines per invoice. Save templates for wording and amounts. PDF with your logo, and optional card pay on the public link.

• Recurring

  Retainers, on time

  Set the amount once. Kontain creates the next invoice each month, quarter, or year. Pause or change anytime.

• Time

  Hours in, invoice out

  Log time against a client. Turn unbilled hours into a draft invoice when you are ready.

• Currencies

  Bill in the money you use

  USD, EUR, GBP, and more. Set a default, or pick one per invoice. No live exchange rates.

• Portal

  Share a link, not a chase

  Clients view, leave a note, download their PDFs, and can pay by card — no Kontain account required.

• AI helpers

  Clearer wording, shorter notes

  Improve invoice text and summarize private notes — you review before Save.

• Export & restore

  Your data, your backup

  Download a ZIP anytime. Restore that file later on this account if you need to.

• Language

  Your language

  English and Spanish now. French, German, Italian, Russian, and Portuguese coming soon.
