What is construction invoicing? 

Construction invoicing is the process of billing clients or customers for services, materials, and labor provided during construction projects. It involves creating and submitting invoices that detail the work completed, associated costs, and payment terms.

A construction invoice typically includes project details, a breakdown of the work completed, costs associated with completing the work (labor, materials, equipment, subcontractors, etc.), retainage amount, and payment terms. 

While there are standardized invoicing styles, like AIA billing, there’s a certain amount of flexibility in creating invoices for construction. The key is to invoice based on the terms of your contract, and be clear and transparent about what each invoice is for. This makes your clients comfortable and keeps the relationship healthy.

What software is best for making construction invoices? 

Contractors have many options when it comes to making invoices. They can do things manually with a word processor and a basic invoice template, pay for dedicated invoicing software, use their accounting software like QuickBooks Online, or use a tool like Knowify which is designed to help them with both project execution and financial management for their projects. 

Invoicing is built into the Knowify workflow, which makes it fast and easy to create and send accurate invoices. Once you build your project budget and plan, and start working, Knowify will allow you to create invoices based on the work you’ve done in just a few clicks. You can send the invoices over email, where the client can sign and pay using ACH or their credit card. It doesn’t get easier.
