While it’s ultimately your clients’ responsibility to pay on time, formatting invoices a certain way can encourage prompt payment. Getting paid on time starts with basics like setting payment terms and holding your clients accountable to them.
Net 15 is one of the most popular payment terms because it ensures you get paid within a few weeks. This arrangement can have a positive impact on cash flow, but it may not work for all client types or projects.
Learn what net 15 payment terms are and how they work, plus how they differ from other options like net 30.
Key Takeaways
- Net 15 payment terms require customers to pay within 15 calendar days, helping businesses collect revenue faster than longer terms like net 30 or net 90.
- Shorter payment terms like net 15 can improve cash flow and reduce delays, but they may not suit clients with longer internal payment processes.
- Clear invoicing practices, including defined terms, accurate due dates, and easy payment options, can encourage faster and more consistent payments.
- Choosing between net 15 and net 30 (or longer) depends on your business needs and your customers’ preferences, since faster payment benefits sellers while longer terms offer buyers more flexibility.
What Are Net 15 Payment Terms?
When you have net 15 payment terms, it means a customer has 15 days to pay an invoice. A common invoice payment term, net 15 allows sellers to get paid much more quickly compared to alternatives like net 30 or net 90.
If cash flow is tight, shorter net payment terms like net 15 can make a real difference. It’s more flexible than requiring customers to pay the invoice upon receipt, but also ensures your business doesn’t have to wait too long for payment. That’s why some companies choose net 15 billing terms over longer arrangements.
Net 15 helps you get paid quicker, but it isn’t always the right option. For example, a shorter deadline might turn away customers or potential customers who find it too restrictive. Remember, cash flow might be tight for them too, so having to pay within 15 days can be a challenge for them depending on their finances.
Example of How Net 15 Payment Terms Work
First, you need to agree to net 15 payment terms with your client, ideally in a written contract. A written agreement makes it official and allows you to hold customers accountable to the agreed-upon terms.
When it’s time to bill your client, you write an invoice that includes all of your work for the specified period. That could be for a one-off project or for a month’s worth of work. Make sure you include all work items, quantities, and charges, as well as the invoice date and due date. Next, you’ll send the invoice to your customer.
With net 15, you would finish the project and send an invoice on April 1. With net 15 payment terms, the customer has 15 calendar days to pay, so the invoice is due April 16. If you aren’t sure about the exact due date, use an invoice due date calculator to avoid potentially costly errors or disputes.
With net 15 invoice terms, the timeline is short, so you benefit from sending the invoice right away. Try offering convenient payment options like online payment or ACH withdrawals to shorten payment timelines even more.
Net 15 vs. Net 30 Terms
Net 15 is a popular type of payment term, but it isn’t your only option. Net 30 is just as popular.
With net 30, the customer gets 30 calendar days to pay. That makes net 30 vs. net 15 payment terms a tradeoff between getting paid faster and giving buyers more time to manage their own cash. This arrangement is more common in business-to-business (B2B) transactions, where buying cycles tend to be longer.
The struggle with invoicing is that many clients prefer longer payment terms, but stretching this out too long can hurt your business’s cash flow in the meantime. A shorter term, like net 15, can help reduce delays and keep receivables moving, which is especially important for smaller businesses. A longer term, like net 30, may be more appealing to customers, but it also means you wait twice as long for payment.
On the flip side, if your business is the buyer, net 30 may be more helpful than net 15 payment terms because it gives you extra time to hold onto cash, manage expenses, and pay with incoming revenue. That is why the “right” option depends on which side of the invoice you’re on.
Do Net 15 Payment Terms Include Weekends?
Invoice terms usually include weekends and holidays, since they’re based on calendar days, not business days.
Some clients may not know this, which is why it’s so important to include the due date on the invoice itself. A short payment window can have a positive impact on cash flow, but it can also catch buyers off guard if they assume weekends don’t count.
In-Summary: Net 15 Payment Terms
Net 15 can be a great option if you want speedy collections without requiring customers to pay immediately. Compared with longer payment terms, net 15 terms can improve cash flow and reduce the time it takes to collect receivables.
With that said, the right option depends on your customers and business model. Ultimately, you need to pick an invoice structure that supports healthy cash flow without hurting your customers.
If your customer needs more time to pay because of confusion over payment terms, extending them can preserve the working relationship. If you need cash to cover expenses in the meantime, financing solutions options like invoice factoring can help you convert these invoices into cash while you wait for customers to pay.
