Invoicing

What is Line Item?

A line item is a single entry on an invoice, estimate, or proposal that describes a specific product, service, or charge along with its quantity, unit price, and total.

A line item is an individual row on an invoice, estimate, or proposal that describes a specific charge. Each line item typically includes a description, quantity, unit price, and the calculated total for that item.

For example, a web designer's invoice might include these line items:

  • Homepage design — 1 x £800.00 = £800.00
  • Inner page design — 4 x £300.00 = £1,200.00
  • Logo revisions — 2 hours x £75.00/hr = £150.00

Well-written line items help in several ways:

  • Clarity: Clients can see exactly what they are paying for
  • Faster payment: Detailed breakdowns reduce queries and disputes
  • Records: Clear line items make bookkeeping and tax returns easier
  • Professionalism: Specificity builds trust with clients

Best practices for writing line items:

  • Be specific — "Website copywriting (5 pages, 500 words each)" is better than "Writing"
  • Use consistent units — hours, days, items, or flat fees
  • Group related work logically
  • If VAT-registered, show the VAT rate per line item or as a clear total

OwnedWork lets you save common line items as templates so you can quickly add them to new invoices without retyping descriptions each time.

Frequently Asked Questions

How detailed should line items be on an invoice?

Detailed enough that the client understands exactly what they are being charged for, but not so granular that the invoice becomes unwieldy. Group small related tasks and be specific about deliverables.

Should I show hourly rates or flat fees in line items?

This depends on your agreement with the client. Hourly rates are transparent and suit time-based work. Flat fees work well for defined deliverables. Use whichever matches your contract or scope of work.
