How to Invoice a Day Rate (With a Sample Day Rate Invoice)

You agreed $600 a day with a client, you have done the days, and now the invoice has to go out. The work was the hard part, but the invoice is where small gaps turn into a two-week delay: a missing date, a half day nobody agreed on, a train ticket folded into the total.

This guide shows what a day rate invoice needs, gives you a sample with real numbers, and walks through building one in Word, Google Docs or a spreadsheet. If you have not settled on the rate itself yet, start with how to calculate your day rate and come back.

What makes a day rate invoice different?#

A day rate invoice is an ordinary invoice with one change: the unit is a day, not an hour or a project. That sounds small, but it shifts what the client checks.

• The days column does the work. Each line shows how many days, the rate per day and the total. The client multiplies the two in their head and moves on.
• Dates matter more than descriptions. A client approving 6 days wants to know which 6. Their records (a booking sheet, a project calendar, a security log for on-site work) are organised by date, so your invoice should be too.
• "A day" needs a definition. Hours, lunch, half days, travel days and overtime all need a rule, agreed before the work. The invoice only applies the rule; it should never be the first time the client sees it.

Get those three right and most day rate invoices are approved on the first read.

What should a day rate invoice include?#

Start with the fields every invoice needs, then add the day-specific ones. In the UK, gov.uk lists what an invoice must include, and it asks for the date the service was provided as well as the date of the invoice. For VAT-registered businesses, HMRC adds the extent of the services and the unit price, which for day rate work is simply the number of days and your day rate. The European Commission's VAT invoicing rules ask for the same pair: the quantity of services and the unit price.

Sample day rate invoice#

Here is a complete example for a designer on $600 a day. It has a normal line, a half day, a travel day at an agreed half rate, and expenses on their own line.

INVOICE                              INV-2026-014
Issue date: 31 Oct 2026      Due date: 14 Nov 2026

From: Sam Rivera Design
      12 Harbour St, Portland, OR 97201
      sam@example.com
To:   Northwind Studio, Accounts Payable
      40 Mill Rd, Seattle, WA 98101

Description                    Days   Rate    Amount
Brand design                      6   $600    $3,600
  Worked 6, 7, 8, 13, 14, 20 Oct
Workshop, half day (21 Oct)     0.5   $600      $300
Travel day to Seattle (22 Oct)    1   $300      $300
Travel expenses, rail (22 Oct)                   $84
  Receipt attached
                              Subtotal        $4,284
                              Tax                 $0
                              TOTAL DUE       $4,284

Payment: bank transfer within 14 days of the
invoice date. Account name: Sam Rivera
Bank: ...  Routing: ...  Account: ...

A few things to notice. The half day shows as 0.5 days at the full rate, so the client can see the logic. The travel day has its own rate because that was agreed separately. The expenses line has no days and no rate, just the amount at cost, with a receipt.

How do you define a "day" before you invoice?#

Most disputes over day rate invoices are not about the rate. They are about what counted as a day. Settle these in your contract or confirmation email, then put each one on its own invoice line when it happens.

The rule of thumb: anything that is not a standard day gets its own line. It keeps the main line clean and makes each extra easy to approve or question on its own.

How to make a day rate invoice in Word, Google Docs or Sheets#

You do not need special software for this. A document or spreadsheet you set up once and copy each time works fine.

1. Set up the header

Put "Invoice" at the top, then your name or business name, address and email. Underneath, add the client's company name, address and the name of whoever approves invoices. Ask the client for this before the first invoice; accounts teams often want a specific entity name or email address.

2. Add a number and two dates

Give the invoice a unique number and never reuse one. Add the issue date and a due date, for example 14 days later. Writing the actual date ("Due 14 Nov 2026") is clearer than a term alone.

3. Build the line items table

In Word or Google Docs, insert a table with five columns: Description, Dates, Days, Day rate, Amount. In Google Sheets or Excel, use the same columns in A to E and put a formula in the Amount column, for example =C2*D2, so the total updates when you change the days.

4. Add one line per service

If you did 6 days of design and 2 days of workshops, that is two lines, not eight. Put the dates worked in the Dates column or on a second line under the description.

5. Add extras on their own lines

Half days, overtime, travel days and expenses each get a separate line, as in the table above. For expenses, leave Days and Day rate empty and enter the amount at cost.

6. Total it up

Add a subtotal (=SUM(E2:E8) in a sheet). Add a tax line only if you are registered for VAT, GST or sales tax and the work is taxable; rules vary by country, so check yours. Then the total due.

7. Add payment details and save as PDF

Write how to pay (bank details, PayPal or Wise) and your terms in one line. In Word or Google Docs, use File, then Download or Save as PDF, and send the PDF rather than an editable file. Keep a copy of every invoice you send: the IRS, for example, says you must keep records as long as they are needed to prove the income on a tax return.

How should you show the dates you worked?#

There are three common ways, and the right one depends on how many days you are billing and how closely the client checks.

• A list of dates on the line. "Worked 6, 7, 8, 13, 14, 20 Oct." Best for up to about ten days.
• Date ranges. "Mon 5 to Fri 9 Oct." Fine for solid blocks, but easy to misread if you skipped a day.
• A calendar or timesheet. A small calendar with the worked days marked, or a separate timesheet, attached or printed on the invoice. Best for many days, several services, or clients who match invoices against their own records.

If a client or agency asks for signed-off proof of your days, timesheet invoices covers how to attach it so the invoice gets approved without a query.

Should you invoice weekly, monthly or at the end of the project?#

Day rates make it easy to bill as you go, because each day has a clear value. Pick a rhythm and agree it upfront.

• Weekly: suits short, intense bookings and new clients you do not know yet. Smaller invoices are approved faster.
• Monthly: the most common rhythm for ongoing work. You bill every day worked in the month on one invoice. Billing a client monthly for days worked walks through it.
• End of project: fine for a booking of a few days. For anything longer, waiting means lending the client your fee for weeks.

How to make a day rate invoice in BillBee.work#

BillBee.work, a free invoice maker for freelancers, is built around day rates, so most of the steps above are already set up.

1. Add the client once. Each client (an "organisation") keeps its own currency, invoice number prefix and saved services with rates, so "Brand design, $600 a day" is there every time.
2. Choose the daily rate type. Each line can be daily, hourly or fixed. A daily line is number of days × day rate.
3. Pick the days on the calendar. Each service has a small calendar; click the days you worked and the line shows the count, for example "6 days", and the amount.
4. Turn on the work log. The "Work log in invoice" toggle prints a small calendar of the days worked on the invoice itself, in every template, so the client sees exactly which days they are paying for.
5. Share the link. The client opens the invoice in a browser without an account. BillBee.work does not email it for you, so copy the link into your own email. On Pro, the client can also download a PDF from the link.

Be aware of what it does not do. There is no half-day option: either save a separate service such as "Workshop, half day" with a daily rate of $300 and pick that day, or add a fixed-amount line. There are no expense lines either, so add a fixed line labelled "Travel expenses, rail (22 Oct)". And there is no notes field, so keep your definition of a day in the contract, and put a one-line payment terms note in your Payment Details, which print on every invoice.
