What to Write in the Description on an Invoice (With Examples)

Why Invoice Descriptions Matter

The description field on an invoice is more than administrative detail. It tells your client exactly what they are paying for, creates a paper trail if a dispute arises, and demonstrates professionalism. A good description removes any reason for a client to query the invoice before paying.

What Makes a Good Invoice Description?

A useful description answers three questions:

What was done?

When was it done (if relevant)?

What deliverable or result did it produce?

It should be specific enough to identify the work uniquely, but concise enough to read at a glance.

Describing Hours-Based Work

For time-billing, include the rate and the hours:

"Brand strategy consulting — 6 hours at $150/hr — 28 April–2 May 2025"

If the client approved the hours in advance or signed off on a timesheet, reference it:

"Web development — 14 hours at $110/hr — as per approved timesheet TS-2025-008"

Describing Product Sales

For products, include quantity, unit, and a brief description:

"Branded A5 notebooks — qty 200 — full colour cover print — $4.50 each"

Referencing Previous Agreements

When the invoice follows a quote, proposal, or contract, reference it:

"Interior design consultation — Phase 1 discovery — as per quotation Q-2025-031"

This single line prevents "I didn't agree to this" conversations.

What NOT to Write

"Various services" — tells the client nothing

"As discussed" — no paper trail

"Invoice for work completed" — meaningless

Internal codes without explanation — the client doesn't know what WEB-DEV-PKG-3 means

The description should make sense to the client without any extra context. If they forward the invoice to accounts payable, that person should understand what it's for.

Multi-Line Invoices

For complex projects or multiple deliverables, use separate line items rather than cramming everything into one description:

Line 1: Discovery and strategy workshop — $1,200

Line 2: Brand identity design — logo, colour palette, typography guide — $2,400

Line 3: Brand guidelines document — 20-page PDF — $800

Total: $4,400

Each line is clear, the breakdown justifies the total, and any query about a specific element can be addressed without disputing the whole invoice.

Keep a Template Library

If you do the same type of work repeatedly, save your best descriptions as templates. Invoicing software lets you build a product/service catalogue — select the item and the description auto-fills. Consistent, professional descriptions every time, with no extra effort.
