THE RIGHT DOCUMENT FOR THE JOB
When to use a invoice
Use it after a milestone, delivery, or recurring billing period when the price, payer, and payment deadline are known.
BEFORE YOU START
What to have ready
- Your business name and contact channel, plus the customer or billing contact
- A unique invoice reference, issue date, and due date
- Itemized descriptions, quantities or hours, rates, discounts, and subtotal
- Taxes, deposits already received, balance due, and the currency
- Accepted payment methods and a contact for billing questions
Tie every line to the agreement
Describe a deliverable, session, product, or time block in plain language. Include the relevant project or purchase reference and show quantities and rates separately. If a fixed fee covers several tasks, say what that fee includes rather than disguising it as unexplained hours.
Make the amount and timing readable
Put subtotal, approved discount, tax treatment, prior deposit, and final balance in a visible summary. State whether payment is due on receipt or on a particular date, and avoid mixing invoice date with service date when they differ.
Leave an orderly payment trail
Name the payment methods you actually monitor and give concise instructions, without placing sensitive account credentials in the document. Save the invoice with supporting approvals and mark it paid, partially paid, or outstanding in your records.
Common mistakes to avoid
- Combining unrelated projects on one invoice so the customer cannot check the charges
- Leaving the currency, due date, or tax treatment implied
- Changing a scope price on the invoice without first documenting the change
A FEW THINGS WORTH KNOWING
Invoice questions, answered
Should an invoice show hours or only a project total?
Show hours and rates when time is billable or the customer expects that detail. For a fixed project, list deliverables and the agreed project fee instead.
How should a deposit appear?
List the deposit as a prior payment with its date or reference, then subtract it from the subtotal or total so the remaining balance is unmistakable.
What should I do when a customer disputes one line?
Ask which line is questioned, provide the matching approval or delivery record, and issue a corrected invoice only after agreeing what changed.
A draft is the beginning—not the final review.
