Trust · Three principles
Audited by anyone. Owned by you.
SolidInvoice has been open source since 2013. The same code runs in our cloud and on a self-hosted server in someone's basement. Pick the path that fits, switch later if you change your mind.
Open and inspectable.
Every line of code is on GitHub under the MIT license. Audit it, contribute to it, fork it. No black box, no hidden tracking.
Yours, even if we vanish.
Self-host the full app on your own server for free. Cloud users can export everything to CSV or PDF at any time, no questions asked.
Built on standards you trust.
Stripe and PayPal for payments. GDPR compliant with EU hosting. Daily encrypted backups on every cloud account.
How it works · Three steps
From signup to first payment in one afternoon.
No demos. No sales calls. No credit card. Most users send their first invoice the same hour they sign up.
Sign up and brand your invoice.
Drop in your logo, pick an accent colour, set your payment terms. Your invoices look like yours from the first send.
Add a client, build an invoice, send a link.
One screen, no wizard. Pick a client, add line items, send a payment-ready link by email or share the URL directly.
Get paid online, automatically.
Clients pay with Stripe, PayPal, or bank transfer. SolidInvoice marks the invoice paid and sends the receipt. Reminders go out on their own.
Features · Six line items
