Compare Net 15 vs Net 30 payment terms. Discover when to use each term, how to avoid late payments, and why 'due upon receipt' hurts your cash flow.
Cash flow stability depends on your invoice payment terms. While many freelancers default to writing "Due Upon Receipt", this phrase frequently backfires because it fails to define a concrete deadline in the client's accounting software.
Understanding Payment Term Definitions
- Due Upon Receipt: Payment is requested immediately upon receipt. In practice, clients often interpret this as "whenever convenient" because there is no specific date to enter into their payment schedule.
- Net 15: Full payment is due within 15 calendar days from the invoice issue date. Ideal for freelancers, contractors, and agencies looking to maintain steady bi-weekly cash flow.
- Net 30: Full payment is due within 30 calendar days. The standard baseline for corporate B2B clients and large enterprise procurement teams.
When to Use Net 15 vs. Net 30
Use Net 15 for one-off projects, new clients, small deliverables under $5,000, and fast-turnaround creative sprints. Use Net 30 for enterprise clients, ongoing monthly retainers, and contracts where you offer a 2/10 Net 30 early-payment discount (2% discount if paid within 10 days).
