How it works

How to make an invoice in under a minute

Klerica’s free invoice generator is a working invoice template right in your browser. No signup, no email gate, no download required to fill it out. Five steps from blank to PDF:

  1. 1

    Add your logo + business details

    Click Upload logoat the top to attach your logo (PNG, JPEG, WebP, or SVG). Then fill in your address, email, and phone so clients can reach you. If you don’t have a logo, the business name renders in its place.

  2. 2

    Add the client

    The Billed To section is where your client’s name and address go. The email field is optional but useful if you’re going to attach the PDF to an email later.

  3. 3

    List what you’re billing for

    Each line item has a description, quantity, and rate. Klerica multiplies them automatically to give you the line amount. Click “+ Add line” for more rows.

  4. 4

    Set tax and (optional) discount

    Enter your tax rate as a percentage. If you’re offering a promo or loyalty discount, click “+ Add discount” and pick either a percentage or flat-amount.

  5. 5

    Download as PDF

    Click Download PDFat the top. Your browser’s print dialog opens with the invoice pre-formatted — choose “Save as PDF” as the destination, hit Save, and you’re done.

Anatomy of an invoice

What belongs on a professional invoice

A few fields are non-negotiable — miss one and you risk a delayed payment or a confused accounts-payable team. The generator above includes them all; here’s the checklist.

  • Your business identity

    Logo, name, address, email, phone — so clients can reach you and confirm who they’re paying.

  • A unique invoice number

    Each invoice should have a unique reference number. Sequential (INV-0001, INV-0002, etc.) is conventional and helps your records stay tidy.

  • Issue date and due date

    When the invoice was sent and when payment is expected. “Net 30” means 30 days from the issue date; “Upon receipt” means now.

  • Client name and address

    Bill-to section — who the invoice is for. Match what they’ll have in their accounting system to avoid reconciliation friction.

  • Itemized line items

    Description + quantity + rate for each thing you’re billing. Specificity prevents “wait, what was this for?” emails later.

  • Subtotal, tax, total

    Show the math. Some clients won’t pay invoices where the total isn’t broken down.

  • Payment instructions

    Tell the client HOW to pay you — bank transfer details, Venmo handle, or that you’ll send a Pay button via email separately.

  • Notes (optional)

    Thank-you, late-fee terms, project reference, or anything else the client should see on this specific invoice.

FAQ

Frequently asked questions

Is it really free? What's the catch?
Yes — no signup, no email gate, no watermark, no usage cap. Klerica earns from paid subscribers who use the full product (saved clients, recurring invoices, online payments, reminders). The free tool just lets you try the invoice quality first.
Will my work disappear if I close the tab?
No. The generator saves to your browser's local storage as you type — including your logo. Come back on the same browser and your fields are still there. Hit Reset at the top to start fresh.
Can I add my own logo?
Yes — click Upload logo and pick a PNG, JPEG, WebP, or SVG. Large images are downscaled automatically, and the logo persists across sessions like the rest of the invoice.
How do I send this to my client?
Download the PDF and attach it to an email yourself. If you'd rather Klerica send it for you — your name in the From, replies to your inbox, a Pay button embedded — that's on a paid plan.
How is this different from other free generators?
Most are a static form: type, download, done. Klerica's free tool is the same shape, but the full product is built on AI extraction — paste a client email or upload an invoice PDF and a draft fills itself in. The generator is the doorway; subscribing adds the AI plus sending, payments, reminders, and recurring schedules.
