We will go over all the essential aspects of contractor invoices, so you can keep your payments and accounting under control.

How to Invoice as a Contractor?

Each project comes with its particularities for a contractor, from timeline services and materials involved and even billing terms. All that needs to be illustrated in the invoice, so you need to learn the basics of independent contractor billing to make sure you handle everything.

The best strategy for billing your clients is to use an independent contractor invoice template because it will save you time, and it will be easier to organize all the information. To make things even more comfortable, here is a step-by-step guide on how to invoice for contract work:

  • Make it evident that the document you are creating is an invoice by mentioning it in the header. This may sound like an unnecessary step, but it's actually essential. Think about the number of documents your clients handle every day. By adding the word 'invoice' right on top, they can immediately identify it.
  • The header also needs to contain your company's name and contact information, as well as a logo or other branding elements you usually use.
  • Once the header is done, add your client's name and contact information below it. But do that after you verify the billing contact because it may be different from the daily business contact.
  • Assign a unique invoice number to your contractor's invoice; both your records and those of your client will benefit from it. It will also help you track the payments easier and refer to this invoice whenever necessary.
  • Add the contract invoice's issue date
  • Offer a detailed description of the services you provided and the individual cost of each item, along with your rates
  • Mention the payment terms and accepted methods
  • Add the total amount due at the bottom, including any taxes that may apply
  • The invoice's due date is essential and must be specified clearly

When it comes to independent contractor billing, details are essential, so make sure to double-check everything and that the client receives all the information they need.

What Is an Independent Contractor Invoice?

An independent contractor invoice is a billing document used by self-employed people who perform project-based work for different clients. It's the paper they use to invoice for contract work. Contractor invoices are among the most versatile bills, as they can apply to various services and billing terms.

It is also called a 1099 invoice, the contract invoice provides the client with a detailed description of the services the contractor has performed. It includes their rates, the hours they worked, materials they used, all adding up to the total amount due. Any independent contractor invoice also provides information connected to the payment, even penalties for overdue amounts.

Overall, the contractor's invoice is an excellent method to communicate with your client, sustain your professional image, and make sure your accounting records are well organized, and you will have no problem calculating your taxes.

When to Send an Invoice?

As a general rule, invoices need to be issued and sent as fast as possible to give your clients enough time to process them and avoid late payments. That's even more important for contractor invoices because many times, you only perform one project for a particular client and need to receive compensation as soon as possible.

Contractors also work on longer projects sometimes. In that case, you cannot wait until the end to get the total amount due because you have many expenses to cover along the way. So, you need to set milestones and invoice for contract work once each level is completed.


If you are self-employed and perform project-based activities, the independent contractor invoice is one of the essential documents for you to use. When you go from one client to another and even handle multiple projects at the same time, it's crucial to keep track of the payments you need to receive.
