How to Create an Invoice and Download a PDF

Updated 30 September 2026 · Fictional example · Based on the current Junocity editor

Start with the work you agreed, the amount you are billing, and the client's billing details. Junocity turns those entries into a document you can review and download as a PDF. You do not need an account.

Read the Terms of Use and privacy notice before entering details. Your entries are not saved by Junocity; download what you need before leaving.

1. Add who the invoice is from and who it is for

Under The people, enter “Your business or name” and “Client name.” Add address and contact details if you need them on the document. Use the agreed billing contact, which may differ from the person you worked with.

A logo is optional. Open “Add your logo” and choose a local PNG or JPEG you have permission to use. The editor accepts up to 2 MB and 4,096 pixels per side, and processes the image locally. It does not accept SVG files or remote image URLs.

2. Set a reference, dates, and one currency

Under The details, choose an invoice number that fits your own records. Junocity does not maintain or guarantee a numbering sequence. A new editor starts with INV-001; check and change it against your records before issuing another invoice. See the invoice numbering examples for a simple system. Enter the issue date and the agreed due date, then add a project reference if useful.

Select the currency you agreed with your client. An invoice uses one currency. Changing USD to EUR, for example, changes the denomination and does not convert your amounts. If you agreed Net 30 or another calendar-day term, the invoice due-date calculator can help check the date.

If the currency is not in the preset list, choose “Other / custom currency,” enter its three-letter code, and confirm 0–4 decimal places before choosing “Apply currency.” Custom precision starts at 2; Junocity does not verify custom codes against a currency registry. Existing preset codes keep their fixed precision. Check the code and rounding convention against your invoice requirements.

3. Describe the work and check the arithmetic

Under The work, give each item a clear description, quantity, and unit rate. For hourly work, use hours as the quantity and your hourly rate as the unit rate. For a fixed-price milestone, use a quantity of 1 and the agreed milestone price. Use “Add item” for another service; the arrow controls change the order.

You can add an optional invoice-level discount as a fixed amount or percentage. Tax is blank initially. Enter a rate only after deciding that the simple one-percentage model is appropriate; leaving it blank is not a finding that the work is exempt.

Fictional arithmetic example

Example Studio bills Demo Works for two units at USD 100.00 each. The subtotal is USD 200.00. A 10% discount removes USD 20.00. In this illustrative example only, a 10% tax on the remaining USD 180.00 adds USD 18.00, giving a total of USD 198.00.

The sample percentages illustrate the calculation; they do not recommend a tax treatment. Junocity rounds each line to the selected currency's precision, sums the lines, applies the discount, and then applies the optional tax using decimal half-up rounding.

For a fuller breakdown, the itemized invoice example combines hourly work and a fixed milestone, explains decimal hours, and shows how line rounding affects the subtotal.

4. Add only the finishing details you need

Use The finishing touches for notes and optional payment instructions. Describe the project or agreed terms clearly. Check any instructions yourself: Junocity does not verify bank details or process payments.

Never enter card numbers, CVVs, passwords, PINs, one-time codes, banking credentials, identity documents, or cryptocurrency secrets. Keep unnecessary personal information off the invoice.

5. Review, download, and open the PDF

The document preview updates as you type. On a phone, switch between “Edit invoice” and “Preview invoice.” Check the names, reference, dates, currency, item descriptions, and total before exporting.

Choose A4 or US Letter, read the terms, and select the agreement checkbox before using “Download PDF” or “Print invoice.” The PDF export supports Latin text and common Western European accents; unsupported characters produce an error before download. Browser printing may support additional scripts, but you still need to inspect the output.

Open the downloaded PDF and review every page, including longer notes and payment instructions. Store it using your own recordkeeping process, then send it through your usual email or client channel. Junocity does not send it, track its delivery, or confirm payment. An invoice and a payment receipt have different purposes; downloading the invoice does not record a payment.

Your final field checklist

Your name/business and the correct client's billing details.
Your invoice reference, issue date, agreed due date, and project reference where needed.
The agreed currency, clear line items, quantities, rates, and checked total.
Any appropriate discount or tax treatment, verified separately.
Accurate notes and payment instructions, with no credentials or unnecessary personal data.
A downloaded document you have opened and checked before sending.

This checklist describes the Junocity workflow, not a universal list of legal invoice requirements. Check the rules and contract that apply to your circumstances. An ordinary PDF may not satisfy mandatory structured e-invoicing or reporting requirements.
