Create invoices online in minutes
With our invoicing software for small businesses you can create invoices online right in the browser, with correct VAT for multiple countries and a professional PDF. Add line items, set due dates and send the invoice to your customer with one click. Email reminders are handled automatically so you get paid on time without chasing customers manually.
Quote with digital signing
Create a polished quote with rich text and images, and let the customer approve it with digital signing right online — completely ad-free. A quote with digital signing shortens the sales cycle, gives a clear record of what was accepted and can be turned into an invoice with one click as soon as the customer says yes.
Recurring invoices on autopilot
Have subscriptions, rent or service contracts? With recurring invoices you set up a template once and let the system generate and email the invoice on a schedule — monthly, quarterly or yearly. You save hours every month and make sure no billing moment is missed in your small business.
SIE4 accounting export to your accountant
When it's time to do the books you export your invoices as a SIE4 accounting export — the Swedish standard imported directly into Fortnox, Visma and other software. Prefer another tool? Generic CSV and SAF-T are available too. That makes working with your accountant or bookkeeper smooth and error-free.
