A step-by-step walkthrough of the guest invoice builder — no account required.
Click "Create New Invoice" from the homepage — no account, no email, no password. InvoiceFlow gives you a temporary session that lasts 1 hour, shown as a countdown in the corner. You can create up to 3 invoices per session.
Enter your business name, email, phone and address. This is saved for the rest of your session, so you only fill it in once. Every invoice you create afterward reuses it automatically.
Pick an existing customer from this session, or select "+ Add New Customer" to enter their name, email, phone and address inline. Once added, they'll appear in the dropdown for your next invoice too.
Add a line for each product or service: pick one you've already used this session, or type a new name, unit price, unit (e.g. "hr", "project") and quantity. The line total updates instantly.
Set the issue date, due date and an overall tax rate. The subtotal, tax and grand total are calculated live in the summary panel. Add any notes your customer should see.
Save your invoice as a Draft or mark it Sent. Guest invoices carry a small InvoiceFlow watermark and don't include a payment link — both come with a paid subscription.
From the invoice preview: download the PDF, print it, email it straight to your customer, or delete it. Everything you create is listed under "Recent Invoices" on the homepage until your session expires.
