Invoice Payment Terms Guide
Choosing the right payment terms: Net 30, due on receipt, and more.
Payment terms define when a client must pay your invoice and under what conditions. The terms you set directly impact your cash flow, client relationships, and the likelihood of timely payment. Choosing the right terms for your business and your clients is a strategic decision that balances getting paid faster with maintaining competitive relationships.
Common Payment Terms Explained
Due on Receipt means payment is expected immediately when the invoice is received. This is the most aggressive term and works well for one-time services, small amounts, or when you have leverage. It is common for retail transactions, medical services, and certain professional services.
Net 15, Net 30, Net 45, and Net 60 mean payment is due within 15, 30, 45, or 60 days of the invoice date. Net 30 is the most common standard in B2B transactions. The "net" period gives clients time to process invoices through their accounts payable department.
2/10 Net 30 means the client receives a 2% discount if they pay within 10 days; otherwise, the full amount is due in 30 days. This incentivizes early payment. Other common discount terms include 1/10 Net 30 and 2/15 Net 45. The discount should be large enough to motivate action but not so large that it significantly erodes your margin.
How to Choose the Right Terms
Consider your cash flow needs first. If your business has tight cash flow, shorter terms or due-on-receipt billing may be necessary. If cash flow is comfortable, offering Net 30 or Net 45 can be a competitive advantage that clients appreciate.
Consider your industry norms. Some industries have established standards—construction often uses milestone-based payments, consulting commonly uses Net 30, and creative agencies frequently require 50% deposits. Deviating significantly from industry norms can cost you clients or create friction.
Assess each client individually. New clients or those with unknown creditworthiness should receive shorter terms or be required to pay upfront. Established, reliable clients may earn longer terms as a reward for their payment history. Adjust terms based on the relationship and the client's track record.
Deposits, Milestones, and Retainers
Deposits require a percentage upfront before work begins, typically 25–50%. They protect your cash flow and signal client commitment. Deposits are standard for custom work, large projects, and new client relationships. Clearly state the deposit amount and when the balance is due.
Milestone payments break a project into phases, with payment due at the completion of each phase. A typical structure is 25% deposit, 25% at midpoint deliverable, 25% at draft completion, and 25% on final delivery. Milestones keep cash flowing throughout the project and reduce risk for both parties.
Retainer agreements involve a recurring monthly payment for ongoing services, often billed at the beginning of each month. Retainers provide the most predictable cash flow and are ideal for ongoing relationships. Define clearly what the retainer includes, how unused hours are handled, and what triggers additional charges.
Late Payment Terms and Enforcement
Specify late payment consequences in your contract and on your invoices. A standard late fee is 1–1.5% per month on the unpaid balance. Some businesses charge a flat fee (e.g., $25) for invoices under a certain amount. The purpose is to incentivize timely payment, not to generate fee revenue.
Include a clause that allows you to suspend work when payments are overdue. This protects you from accumulating more exposure with a non-paying client. The clause should specify how much overdue time triggers suspension and how work resumes after payment.
Be consistent with enforcement. If you never charge late fees, clients learn that your terms are negotiable. If you consistently follow your stated policy, clients respect the terms. You can always waive a late fee for a good client with a reasonable explanation, but having the policy in place gives you leverage.

Frequently Asked Questions
What does Net 30 actually mean?
Net 30 means the full invoice amount is due within 30 calendar days of the invoice date. "Net" indicates no discount applies—the client pays the full amount. If an invoice is dated January 1 with Net 30 terms, payment is due by January 31.
Can I change payment terms with an existing client?
Yes, but communicate the change in advance and provide a reason. For example, "Starting next quarter, our standard terms will be Net 15 instead of Net 30 to better align with our business needs." Give clients notice and, if possible, apply the change to the next contract renewal rather than mid-agreement.
Are early payment discounts worth the cost?
The math depends on the discount rate and your cost of capital. A 2/10 Net 30 discount equals about 36% annualized return for the client—and costs you 2% to receive cash 20 days sooner. If you would otherwise need a line of credit at 8–12% to cover the cash gap, the discount may be cheaper than interest. For businesses with healthy cash flow, discounts may not be necessary.
