Invoicing for consultants
Consultants often bill a project or retainer fee rather than hours, sometimes with expenses on top. The generator is pre-filled with a flat engagement fee and an expenses line — switch to hourly by changing the quantity to your hours and the rate to your hourly fee.
A consultant invoice should name the engagement, show the fee basis (project, retainer or hourly), list reimbursable expenses separately, and state payment terms. Reference the statement of work or contract so the client can match the invoice to what was agreed.
For ongoing work, send a fixed retainer invoice on the same day each month — keep the description consistent so the client’s accounts-payable team approves it quickly. Bill expenses on their own lines so they’re easy to review.

Frequently asked questions
How do consultants invoice clients?
State the engagement and the fee basis — a flat project fee, a monthly retainer, or hours × rate — list any reimbursable expenses separately, and reference the agreement. The generator pre-fills a project fee plus an expenses line; edit them, set your terms, and download a PDF.
What payment terms should a consultant use?
Net 15 or net 30 is standard; retainers are often billed in advance or at the start of each month. For new clients, an upfront deposit reduces risk. Put the terms and due date on the invoice — the generator sets the due date from the net-days you choose.
How do I send an invoice to a client?
Download the invoice as a PDF here, then email it to your client as an attachment with a short note and the amount and due date in the subject line. A PDF is the standard format because it looks the same on every device and can’t be edited by accident. Keep a copy for your own records.
Do I need to charge sales tax on an invoice?
It depends on what you sell and where. Many services aren’t taxable, while physical goods usually are, and rates vary by state and even city. Leave the sales-tax toggle off if you don’t collect it; turn it on and enter your rate if you do. When you’re unsure whether a sale is taxable, check your state’s rules or ask a CPA.
Is this invoice generator free?
Yes — it’s completely free with no account, no watermark and no limit on how many invoices you create. Everything runs in your browser, so your client and pricing details never leave your device, and your own business info is saved locally so you don’t retype it next time.
