Itemized invoice

An invoice that lists the work as separate lines with quantities and rates rather than one total.

Part of the invoicing glossary, plain definitions of the words on an invoice, a quote and a job.

In one line

An invoice that lists the work as separate lines with quantities and rates rather than one total.

Also called a detailed invoice, or a broken-down invoice.

What it means in practice

Itemizing is what makes an invoice checkable. A client can accept or query a single line without holding up the whole payment, which is exactly what you want when one fitting is in dispute.

It also protects the price. Three lines that add to $1,800 read as work done; one line that says $1,800 reads as a number to negotiate.

Covered in full in the guide to make an invoice.

Example. Electrical panel replacement $650, four sockets at $55, two hours of testing at $95.

Where this document sits in the run from first inquiry to money received. Each one answers a different question, which is why sending the wrong one stalls the job.

Where it shows up on the paperwork

The body of the invoice: one row per piece of work, each with a description, a quantity, a rate and a line total, adding up to the subtotal.

What goes wrong

  • Itemizing your internal steps rather than the client's outcomes, which invites a line-by-line negotiation.
  • Hiding materials inside labor, so a client who queries the rate is really querying the materials.
  • One line for everything, which turns the whole invoice into a single yes or no.

Common questions

Should every invoice be itemized?

Any invoice a client might query, which is most of them. A repeat client on a fixed monthly fee is the exception, and even then the line should say what period it covers.

How detailed should the lines be?

Detailed enough that the client can accept most of the invoice while asking about one thing. That is usually the level your trade bills in: per door, per linear foot, per hour, per visit.
