Create your account and send your first invoice

Go to quillstack.example/signup and register with your email or a Google account. You get a 14-day trial of the Solo plan; no card is required. After the trial ends, the account moves to the Free plan automatically unless you pick a paid plan.

Open Settings → Business profile and fill in your legal name, address, tax ID and logo. These details are printed on every invoice. You can change them later, but invoices that were already sent keep the details they were sent with.

1. Click New invoice on the dashboard.
2. Choose a client or create one inline with a name and email.
3. Add line items: description, quantity and unit price. Taxes are applied per line.
4. Set the due date. The default is Net 14 and can be changed in Settings → Invoice defaults.
5. Click Send. The client receives an email with a link to view and pay the invoice online.

A draft is saved automatically every few seconds, so you can leave and finish later from Invoices → Drafts.
