Freelancer Invoice Builder

The fastest way to bill a client

Most invoice tools are overkill for a one-person operation. This builder keeps it to the essentials freelancers actually need: who you are, who you’re billing, the work you did, your rate, an optional tax line, and a payment block where you paste your PayPal, bank, or crypto details. It calculates totals as you type and gives you a clean invoice to copy or print.

How it works

Each line is quantity × rate, where quantity is your hours (for hourly work) or units (for fixed deliverables). The tool sums every line into a subtotal, applies an optional percentage discount, then adds tax on the discounted amount:

line total = quantity × rate
subtotal   = sum of all line totals
taxable    = subtotal − discount
tax        = taxable × (tax rate ÷ 100)
total      = taxable + tax

The currency selector formats every figure for the chosen currency, and the payment block is free-form text so it works for any method.

Tips and example

• Hourly example: 14 hours of design at a £55 rate → one line with quantity 14, rate 55, total £770.
• Fixed-price example: a logo package for $400 → quantity 1, rate 400.
• Send invoices the day work completes — prompt invoicing is the single biggest driver of getting paid on time.
• Add clear payment terms in notes, e.g. “Net 14, 2% late fee per month”, so expectations are explicit.
