Bottom line: set up your business details once, create an invoice with line items, and share the link or email it. Add a Stripe Payment Link or PayPal.me address and the client can pay in one click. No monthly invoicing-app fee, no percentage cut.
Step 1: business details, once
Open Quick Invoice and click Business details. Add your business name, the email you want on invoices, an address if you need one, and your payment link. Every invoice uses these unless you override them per invoice.
If you do not have a payment link yet, the fastest route is a Stripe Payment Link: in your own Stripe account, create a product, set the price to "customer chooses", and copy the link. PayPal.me works the same way. Either takes about two minutes.
Step 2: the invoice
Click New Invoice. Client name and email, a due date, and line items. Each line has a description, a quantity and a unit price; the total is calculated for you. Add a note if you want payment terms visible on the invoice ("Net 15. Thanks!").
Numbers are sequential per account, starting at INV-0001, so your accountant will be happy.
Step 3: send it
Two options:
- Copy the share link and paste it anywhere: Slack, WhatsApp, a text message. The link opens a clean invoice page with a print button.
- Send email. We email the client a branded message with a "View and pay" button. You can add a personal note first.
Either way, the invoice flips from Draft to Sent. If you share manually, click "Mark sent" so the tracking starts.
What the client sees
A single page with your details, their details, the line items, the total, and a big Pay now button pointing at your payment link. If they prefer bank transfer, your payment instructions appear under the button. The page is printable, so a client who needs a PDF for their records gets one from the browser.
The first time a sent invoice is opened, your card shows "viewed" with a timestamp. That ends the "did you get my invoice?" email forever.
Step 4: mark it paid
When the money lands, click Paid. The invoice page updates to show it is paid, and the "Paid this month" tile on your dashboard goes up. Overdue invoices are counted automatically from the due date.
What this is not
Quick Invoice does not reconcile bank feeds, calculate tax, or do recurring billing. It is for the freelancer who sends a handful of invoices a month and resents paying $15 a month for the privilege. If you send hundreds, buy accounting software.
