Why contract workers should send professional invoices

Illustration of invoice being sent

As a professional, you bring experience, skills, and knowledge to every contract you work on. You need clear, itemized invoices that include details of all the great work you have provided, as well as show your clients the advantage of hiring you on contract again, and refer you to their business associates and friends.

An orderly, well-designed invoice also instills confidence and credibility in your reputation and excellent work. You are an expert in your contracted field – make sure your invoice reflects your skill and professionalism.

How to fill out your contract work invoice

Once you've downloaded your free invoice template, you'll need to customize it to fit your specific business. Here are the 10 key things to include on your invoice:

  1. Title and Description: Name the project and briefly describe what type of work your client is being invoiced for.
  2. Company Details: Add your company name, address, phone number, and logo to the top-right corner.
  3. Customer Details: Under "Bill To", add your customer's name, address, and contact information.
  4. Invoice Number: Include a unique invoice number to help you track down this invoice in the future. You can format this based on sequence and customer. For example, if you're sending your very first customer their first invoice,  the invoice number could be 001-001.
  5. Dates: Include the date when your invoice has been issued and the date when payment is due.
  6. Line Item: Add individual line items for each unique good or service you provided. For each line item, include a brief description, quantity, individual unit price, and total price.
  7. Subtotal: Add up the subtotal of your goods or services, before tax has been applied.
  8. Tax: Indicate the tax rate applied to the subtotal. This is legally required to provide on invoices, and your rate may differ depending on where you run your business.
  9. Total: Outline the total amount due from the customer, after tax.
  10. Notes: Include any additional info your customer should know, including terms of service and payment terms (for example, payments are due 30 days after the invoice has been issued).

When is the right time to send an invoice to your contract clients?

The right time to send an invoice varies with the type of contract services you provide. If it is a short job or project, some contract workers invoice at completion.

As an independent business owner you need to keep the revenue coming in, so for longer contracts, many contract workers ask for a percentage of the payment up front, with the remainder on completion of the contract, or send in bi-weekly or monthly invoices.

Whatever payment time period you choose, make sure it’s clearly noted on each invoice, and clarify what portion of the final ‘cost’ has been paid to date.
