How to create an invoice
A complete invoice is a request for payment that your client’s accounts team can process without writing back. This guide covers the fields that matter, how consultants and freelancers usually number invoices, and where a generator or a billing workspace saves time.
Put your business details and the client’s legal billing name on the document, give it a unique sequential number, itemise the work with quantities and rates, add tax and a specific due date, and include payment instructions. Use the free invoice generator if you need a PDF now, or fylt Billing if you want invoices tied to the client record.
The invoice template that actually gets paid
Freelancers and consultants lose days to invoices that look like emails. Accounts payable needs the word “Invoice”, a number they can file, a due date they can schedule, and bank or payment details they can copy. Missing any of those is the usual reason a “quick invoice” sits unpaid.
- Identify the parties. Put your legal business name, address, and tax registration on the invoice, and use the client's legal entity name and billing address — not just a contact's first name.
- Number and date the invoice. Use a unique sequential invoice number, an issue date, and a specific calendar due date rather than 'on receipt'.
- Itemise the work. One line per deliverable with quantity, unit price, and line total. Specific descriptions are paid faster than vague ones.
- Add tax, total, and how to pay. Show subtotal, tax, and grand total in a stated currency, plus payment instructions for the methods you actually accept.
Invoice generator for consultants and freelancers
If you send a handful of invoices a month, a one-off generator is enough. The free invoice generator runs in your browser: line items, tax, and totals update live, then you print or save a PDF. Nothing is sent to a server.
If the same clients come back, you need history: invoice status, partial payments, retainers, and a record on the client profile. That is fylt Billing — invoicing and payment records in the same workspace as CRM and projects. fylt Billing and fylt Workspace do not collect client payments. They help you create invoices, record payments you receive, and show clients how to pay. Optional paid booking on Calendar can be processed by Razorpay or PayPal. fylt does not hold or route customer funds.

Your business details and tax number if registered, the client's legal name and billing address, a unique invoice number, issue and due dates, itemised lines, tax, the grand total, and payment instructions.
Use a gap-free sequence such as INV-2026-001. Many practices add a client code. Never reuse a number; tax authorities expect invoices to be unique and traceable.
