How to create an invoice online free

Want to create invoice online free? Fill in the form above, check the totals and download a PDF. A good invoice generator free of design work takes about two minutes. Freelancers, agencies, consultants, wholesalers and traders all use the same flow.

Follow four steps:

  1. Add the basics. Enter your business name, your client's details, the invoice number and the dates. Upload your logo if you have one.
  2. Add line items. Type the item name, quantity and rate. The invoice maker calculates each amount and the total.
  3. Set the currency and extras. Choose from 150+ currencies. Add tax, a discount or extra charges.
  4. Pick a look and share. Choose a template and a color. Download the PDF with a free account, print it, or send your online invoice by email or messaging app.

Check three things before you send. The invoice number must be new. The client name must match your contract. The due date must be right. Clients pay against that date, so a typo there costs you days.

What every invoice needs

A clear invoice gets paid faster than a clever one. Include these fields:

  • Your business name, address and contact details
  • Your client's name and billing address
  • A unique invoice number
  • The issue date and the due date
  • Line items with quantity, rate and amount
  • Tax, discounts and the total, with the currency
  • Payment instructions, such as bank details
  • Terms or notes, such as late payment fees

Tax rules and mandatory fields differ by country. Check your local requirements before you send your first invoice.

Invoice generator, invoice template or invoicing software?

You have three ways to make an invoice. Each one fits a different volume.

  • Invoice generator. An online invoice generator builds the invoice from a form and does the maths. It suits one-off jobs and occasional billing.
  • Invoice template. A template is a file you edit yourself. Browse our free invoice templates if you prefer a blank layout you can fill in and print.
  • Invoicing software. Software stores your clients, sends reminders and tracks payments. Invoicing software for small business pays off once you bill every week.

Use a simple test. If you re-type the same client details more than twice a month, a one-off invoice creator costs you more time than it saves.

Example: one invoice in two currencies

Illustrative example. The figures and the exchange rate are made up.

Maya runs a small design studio. She bills a client in Berlin. She wants the invoice in US dollars, with a euro total beside it.

Website design ->1 * 1,200.00 = 1,200.00

Hosting setup -> 1 * 150.00 = 150.00

Content upload -> 4 hours * 45.00 = 180.00

  • Subtotal: 1,200.00 + 150.00 + 180.00 = 1,530.00 USD
  • Tax at 10%: 1,530.00 × 0.10 = 153.00 USD
  • Total: 1,530.00 + 153.00 = 1,683.00 USD
  • Exchange rate applied: 1 USD = 0.92 EUR
  • Euro total: 1,683.00 × 0.92 = 1,548.36 EUR

Maya's client sees both totals and the rate she used. Nobody has to ask how the euro figure was reached.

Invoicing features that go beyond a basic invoice creator

A single PDF solves today's invoice. These features solve the next hundred. They live in your Refrens account, and some sit on paid plans. Pick the ones your billing needs.

Get paid on time

Automated payment reminders. Set the schedule once. Refrens sends reminders by email and WhatsApp, so you stop writing chase messages by hand. Maya's client has 15-day terms. The first reminder goes out before the due date. The next one follows if the invoice stays open.

Scheduled invoices and reminders. Create the invoice today and schedule it for the first of next month. The reminders follow the same plan. You finish the work in one sitting and the sending happens on its own.

Recurring invoices. A hosting agency bills the same 300 a month to the same clients. It builds each invoice once, sets it to repeat monthly and stops rebuilding it every month.

Bank details for payment collection. Add your bank details once. Every invoice then shows the client exactly where to pay.

Invoice payment records. Record each payment against its invoice. A client pays 600 on a 1,200 invoice. The record shows what you received and what remains.

Know where every invoice stands

Invoice tracking via email. Send the invoice by email and see when your client opens it. An invoice that stays unopened for three days tells you to pick up the phone.

Acceptance history. See whether your client accepted the invoice, and when. A dated record ends the "I never agreed to this" conversation before it starts.

Audit trail. Every change leaves a record: who edited the invoice, what changed and when. A teammate changes a rate on a sent invoice? You see it.

Linked invoices. Each invoice links back to the lead, quote or proforma invoice that created it. A client questions a price. You open the original quote from the invoice and settle it in a minute. Pair this with quoting software and the whole chain from quote to invoice stays in one place.

Make the invoice look like your business

Templates and colors. Choose an invoice template, then change its color to match your brand.

Letterhead, custom fields and custom columns. Add your letterhead. Add custom fields, such as a project code or the client's PO number. Add custom columns, such as hours or a per-line discount. A consulting firm bills "Hours" and "Rate". A studio bills "Quantity" and "Rate". Same invoice maker, two different layouts.

SKU and product images. Add a SKU and a photo to each line item. A wholesaler sends a 40-product order. The buyer matches every line to the goods on the dock without a phone call.

Applied exchange rate. Show the rate you used when you bill in a foreign currency, as Maya did above. Your client can check the conversion without asking.

Signature. Sign the invoice on screen or upload an image of your signature. Your client sees a signed document that comes from you.

Work faster as your volume grows

Save the format and reuse it. Set up your columns, notes, terms and colors once, then save the format. Reuse it on any invoice without changing anything. Or save a format for each client. One client needs a PO number field. Another wants an hours column. Each gets the right layout every time.

Bulk upload. Upload a sheet of invoices in one go. An agency with 60 retainer clients raises its month-end invoices in a single session instead of 60.

Turn one document into the next

Convert an invoice into a purchase order, debit note or credit note. A client returns one item. You raise a credit note against the original invoice and leave the original untouched. Need a standalone order? Use the purchase order form.

When the free invoice generator is enough

The form above creates one invoice at a time. It does not store your clients, chase late payments or track who opened what. Those jobs live in your Refrens account.

Use the generator when:

  • You send a few invoices a month.
  • You need a PDF today.
  • You want to test how your invoice should look.

Move to invoicing software when you bill the same clients every month, chase payments by hand or need a record of every change. You need a free account to download the PDF. The free plan covers 15 documents a year across all document types, and free documents carry a small Refrens branding.

An invoice is not a quotation or a proforma invoice

Three documents look alike and do different jobs.

  • A quotation offers a price before work starts. Make one with the free quotation generator.
  • A proforma invoice previews the charges before delivery. Start from our proforma invoice templates.
  • An invoice asks for payment for work done or goods delivered.

Issue them in that order and link each to the one before it. Your records then show the full story of every sale.

Generate your invoice in minutes

Scroll up, fill in the form and generate invoice PDFs as often as you need. The free invoice generator covers one-off jobs. When billing grows, your Refrens account adds reminders, recurring invoices and tracking. More than 150K businesses across 170+ countries already bill their clients with Refrens.

Can I bill in a different currency?

What is the difference between an invoice generator and an invoice template?

A generator builds the invoice from a form and calculates the totals for you. A template is a file you edit yourself in Word or Excel. Use a generator for speed. Use a template when you want full manual control.

What is the difference between an invoice and a receipt?

An invoice asks for payment. A receipt confirms that you received it. Send the invoice first and issue the receipt after the money arrives.

Can I reuse the same invoice format for repeat clients?

Yes. Save your format once, then reuse it on any invoice. You can also save a format for each client, so every client gets their own layout and fields without editing.

What happens to my data if I cancel or leave Refrens?

If you cancel or downgrade your plan, you keep access to your data. You can download your invoices, quotations, client records and reports at any time, and Refrens does not delete your data when you cancel. Your data stays available under the free plan limits. To remove your business, open Business Settings, go to General Settings, then Security, and choose Remove Current Business. Confirm with your password, then email care@refrens.com with your reason. Removal deletes the account for good and you lose access to its data, so download what you need first.
