About 1invoice.online
We make invoicing, quotes and customer registers simple — for real small businesses and associations that want to spend their time on their work, not on accounting software.
Who we are
1invoice.online is run by Dtech, an independent Swedish tech company founded in 2023. We build cloud tools for small businesses, associations and solopreneurs who need tools that work without costing a fortune every month.
The platform is developed in Sweden, hosted in the EU on Supabase's European servers, and built on GDPR principles from the ground up — not as an afterthought.
Our philosophy
- Free really means free — associations never pay for the basics. We fund the free tier with unobtrusive ads, not with your data.
- Companies never see ads — the professional tone matters when you send quotes to your customers. Our B2B mode is ad-free by default.
- Design guarantee — quotes and invoices sent to end customers are always 100 % ad-free. Your deliverable looks like your deliverable.
- GDPR without hassle — export all your data whenever you want, delete your account whenever you want, we never sell your data.
The tech behind it
1invoice.online is built with modern, battle-tested tools:
- Next.js 14 + TypeScript — fast, server-rendered web app
- Supabase — PostgreSQL with row-level security for safe multi-tenancy
- Stripe — payments with automatic VAT / sales tax handling
- Resend — reliable transactional email
- Our own EU VPS — full control over operations and data
