Freelancing Guide — Invoicing & Getting Paid
You can do brilliant work and still go broke if your invoicing is a mess. This guide covers the four things every freelancer needs to get right: how to set rates, what to put on an invoice, how to agree terms that protect you, and how to chase late payment without losing the client.
Setting your rates
Charging by the hour is simple and protects you against scope creep, but it punishes you for being fast. Best when work is open-ended or the scope genuinely cannot be predicted.
A flat fee for a defined deliverable rewards efficiency and gives the client certainty. Risky if the scope expands — always pair it with a written scope and a change-order process.
A monthly fee for a pre-agreed amount of availability or output. Predictable income for you, predictable cost for the client. Define what counts as in-scope and what is extra.
Pricing tied to the business outcome of the work — for instance, a share of revenue generated. The hardest to sell, the most lucrative when it works, and the most resistant to scope arguments.
Whichever model you pick, base your number on three things: what you need to earn after taxes and unpaid time, what the market pays for your skill and seniority, and what value the work creates for the client. Most freelancers undercharge because they anchor on the first number and ignore the third.
What to put on your invoice
- Your name (or company name), address and tax ID if registered
- Client's name, billing contact and address
- Unique invoice number, issue date and due date
- Clear description of the work delivered
- Hours or quantity, rate, and line total for each item
- Subtotal, applicable tax and grand total
- Bank or wallet details and accepted payment methods
- A short note referencing the project or PO number
Describe the work in plain English, not vague labels. 'Logo design — 3 concepts, 2 revision rounds, final files in SVG, PNG and PDF' is approved in minutes; 'design work' will get an email back asking what you mean.
Payment terms that protect you
Agree terms before you start work, not after. Two terms matter most: how much the client pays up front, and when the balance is due. For projects above a few hundred units of currency, ask for a deposit of 30 to 50 percent before you begin. This screens out clients who never intended to pay and gives you cash to live on while you work.
Set a short due date — Net 7 or Net 14 — rather than the generous Net 30 that big companies default to. State the due date as a specific calendar date on the invoice, not as '30 days from receipt', and include a late-payment clause in your contract that lets you charge interest or stop work if payment is overdue.
Chasing late payments
Most late payments are oversights, not refusals, so assume good faith and escalate gradually. A predictable cadence keeps you calm and stops the client from feeling ambushed:
- Day 0: send the invoice the moment you deliver the work, with a polite note.
- Day 1 after due: a friendly email assuming the client simply forgot.
- Day 7 after due: a firmer reminder, restating the invoice number and amount.
- Day 14 after due: a phone call or message, not just email.
- Day 30 after due: a final notice before involving a collection service or small-claims court.
Keep every reminder short, polite and factual. Reference the invoice number, the amount and the original due date. Never threaten in the first three messages — clients talk to each other, and a reputation for being reasonable is worth real money over a career.
Tools
You need three tools: a free invoice generator that produces clean PDFs without a watermark, a simple spreadsheet or tracker to log every invoice you issue, and a separate bank account so client payments do not mingle with personal money. Everything else — proposal software, time trackers, project management apps — is optional and only worth paying for once the work justifies it. Many freelancers run a profitable business on nothing more than a generator, a spreadsheet and a calendar.
Taxes as a freelancer
Set aside a fixed percentage of every invoice — 25 to 35 percent is a reasonable starting point in most jurisdictions — into a separate account the day the client pays. That money is not yours; it is the tax authority's, and you are simply holding it. Track every business expense, because most are deductible: software, equipment, a portion of home utilities if you work from home, professional development and travel for client work. Register for GST, VAT or sales tax the moment your turnover approaches the threshold in your country — registering late can mean absorbing tax you cannot recover. When in doubt, spend an hour with an accountant; it is the best money a freelancer can spend.
