Frequently Asked Questions

There are many types of construction documentation that have similarities. What makes a purchase order (PO) similar to a contract is the workflow. When a PO has been submitted and accepted, it becomes a legally binding document. In fact, a purchase order is a legally binding agreement even when there is no existing contract between a supplier and a contractor.

Contracts in the construction industry are a lot more detailed than a purchase order. For this reason, a substantial transaction, especially when it’s spread across a longer period of time, requires a contract in addition to purchase orders.

Invoices are documents that suppliers send to buyers, where they summarize the products (equipment or inventory) that they have purchased or have agreed to purchase. Invoices will usually reference a purchase number, if there is one, to assist with record-keeping and avoid confusion. These two types of construction documents supplement each other but they serve different purposes.
