Common Invoice Payment Terms Used in Construction

Below is a table summarizing the most used terms in the construction industry:

Term	Definition	Typical Use
Net 30	Payment is due 30 days after the invoice date	Most common term in commercial jobs
Net 15	Payment is due 15 days after the invoice date	Used for smaller or short-term jobs
Due on Receipt	Payment is expected immediately upon invoice receipt	Used for new or high-risk clients
Progress Payments	Payment made periodically based on work completed	Standard in long-term projects
Retainage	A portion (5-10%) of payment is withheld until project completion	Ensures final job completion
Early Payment Discount	Incentivizes faster payment (e.g., 2% off if paid in 10 days)	Encourages on-time payments

Each of these invoice payment terms has its pros and cons, and the right one depends on your project scope, client relationship, and financial needs.

What Is Net 30 and Is It Right for You?

If a client has net 30 payment terms, they have 30 days to pay the bill. This is the most common term in building because it gives the client flexibility while giving the contractor a steady flow of cash. 

Pros:

• Familiar to most clients

• Predictable billing cycle

• Easier to enforce legally

Cons:

• Can delay cash flow

• Risk of late payments without penalties

When to use it: Net 30 works well for commercial projects and clients with a good payment history.

What Are Progress Payments?

It's not always possible to wait to send out an invoice until the end of a construction job. This is where payments for progress come in.

With progress payments, you can bill the client regularly (every month, every two weeks, or based on goals), based on how much work you've finished. These rules work well for big or long-term projects.

Benefits include:

• Regular cash inflow

• Better project accountability

• Reduced financial risk for both parties

This model is often paired with AIA billing or other formal payment application timelines.

How Does Retainage Affect Your Cash Flow?

When you're in the construction business, retention means holding back a portion of each payment (usually 5–10%) until the job is mostly finished. This keeps the client from getting work that isn't finished or isn't right.

Retainers are common in contracts, but they can mess up your cash flow if you aren't careful with how you handle them.

How to handle retention:

• Keep track of it separately in your financial software

• Know the terms of the release (punch list, final check).

• Talk to the client about when the release will happen. 

Should You Offer Early Payment Discounts?

Offering an early payment discount, such as “2/10 Net 30” (2% discount if paid within 10 days), can be an effective incentive for timely payments.

Consider this if:

• You’re experiencing frequent late payments

• You need faster cash flow to cover labor or materials

• The discount is worth the early payment tradeoff

Just ensure your profit margins can absorb the discount.

Best Practices When Setting Payment Terms

Choosing invoice terms is only part of the process. You also need to communicate them clearly and enforce them effectively.

Here are some best practices:

• Include payment terms on every invoice

• Reinforce terms in your contracts

• Follow up on unpaid invoices consistently

• Use construction billing software or spreadsheets to track due dates

• Apply late fees or interest, if allowed by law and stated in your agreement

Bookkeeping Tips for Tracking Invoice Terms

To manage your billing successfully, you’ll need a system for tracking:

• Invoices sent and due dates

• Retainage balances

• Discounts offered and taken

• Late fees incurred

Whether you use Excel, QuickBooks, or a dedicated contractor billing system, consistency is key. Always reconcile your project billing with your general ledger.
