A cash flow gap is the period between when your business needs to pay expenses and when customers pay you. When the business operates on net 30 payment terms or net 60 payment terms, this discrepancy can cause problems with payroll, supplier payments, rent, inventory, and everyday business operations, even with high sales figures.
Key Takeaways:
- A cash flow gap occurs when business payments become due before you receive customer payments.
- Net 30 payment terms mean that payment is due 30 days after the invoice date.
- Net 60 payment terms mean payment is due 60 days from the invoice date.
- Even profitable enterprises may face cash flow problems if major clients are slow to pay.
- Funding for small businesses, such as cash flow gaps, can help support short-term essentials for businesses that are waiting for unpaid invoices to be paid.
What Is a Cash Flow Gap?

A cash flow gap is the delay between when money leaves your business to cover expenses and when payment actually comes in from completed work or sales. It often happens when bills for rent, payroll, materials, suppliers, or operating costs are due before customers pay their invoices.
For example, you may finish a project today, send the invoice tomorrow, and then wait 30 or 60 days for payment. During that waiting period, your business may still need to pay suppliers, insurance, software, fuel, taxes, rent, and other operating expenses.
A cash flow gap is a timing issue. Your business may have earned revenue and issued an invoice, but the money is still sitting in accounts receivable and has not yet reached your bank account.
What Are Net 30 Payment Terms and Net 60 Payment Terms?
Net 30 payment terms give a customer 30 days to pay an invoice, while net 60 terms give 60 days. These terms are common in B2B transactions, but they can also apply to small businesses, which may have to cover costs in advance.
Net 30 means the invoice payment is due within 30 days of the invoice date. What do net 60 payment terms mean? It implies that the customer has twice as much time to pay, which means your business requires more working capital to stay afloat.
| Payment Term | What It Means | Cash Flow Impact | Best Practice |
|---|---|---|---|
| Net 30 | Client pays within 30 days | Moderate waiting period | Invoicing quickly and following up before the due date |
| Net 60 | Client pays within 60 days | Longer cash flow gap | Build reserves or arrange backup working capital |
| Late Payment | Client misses the agreed date | Higher pressure on payroll and suppliers | Send reminders and review future payment terms |
| Deposit + Balance | Client pays part upfront | Reduces upfront risk |

How Do Businesses Survive Long Customer Payment Terms?

To keep a business running with extended customer payment terms, it must be able to forecast cash requirements, issue invoices promptly, follow up on payments promptly, accept deposits, manage expenditures, and have short-term working capital available on demand. Statistics Canada reported that 49.3% of businesses requested external financing in 2023. The objective is to continue operations while there are still unpaid invoices.
Practical steps include:
- Send invoices immediately after work is completed.
- Include clear due dates and payment instructions.
- Follow up before the invoice becomes overdue.
- Offer early-payment discounts when it makes financial sense.
- Ask for deposits on large orders or labour-heavy projects.
- Match supplier terms to customer payment terms where possible.
- Keep a rolling 30-, 60-, and 90-day cash flow forecast.
Working capital for net-30 payment terms can be especially useful when your business is growing. Growth often requires paying for labour, inventory, and materials before the customer’s payment is received.
Net 30 vs Net 60 Payment Terms: Which Creates More Cash Flow Risk?
Typically, net 60 payment terms pose a higher risk to cash flow than net 30 – the company waits twice as long before being paid. The longer the waiting time, the more cash your business must tie up without slowing operations.
Net 30 might be affordable when you have good margins and pay the invoice on time. Net 60 can be harder if you have weekly payroll, supplier bills, rent, or inventory costs due before the client pays.
A simple rule is this: the longer your customers take to pay, the more critical cash flow planning becomes. If several large clients pay on net 60 terms, a single delayed invoice can disrupt your entire operating cycle.
Why Do Profitable Businesses Have Cash Flow Gaps?
Cash flow pressure is not unusual. According to Statistics Canada, 65% of SMEs said maintaining sufficient cash flow or managing debt was an obstacle to growth in 2023. Profitable businesses can have cash flow gaps because profit and cash timing are not the same thing. A business may make a sale today but wait 30, 60, or more days before the money reaches its bank account.
This is common across industries, including construction, transportation, staffing, wholesale, manufacturing, trades, professional services, and B2B supply. A company may look healthy on paper, but if customers pay slowly, the business can still struggle to meet short-term obligations.
This is why many owners ask, “How do businesses survive long customer payment terms?” The answer is planning, faster collections, tighter payment policies, and, when appropriate, cash flow financing for unpaid invoices, which Canadian businesses can use to bridge a temporary gap.

FAQs:
Can I get funding if my clients pay on net 60 terms?
Yes, some businesses can obtain funding even if their clients pay on net 60 terms. Lenders may review revenue, invoice history, cash flow, time in business, and repayment capacity before deciding on the loan. The more you have sold and collected, the more likely you’ll be able to cover the cash flow gap.
How long can a business survive a cash flow gap?
A business can manage a cash flow shortage if it has sufficient working capital to cover bills before receiving payment from customers. The safe time frame depends on payroll, supplier bills, rent, taxes, debt payments, and cash reserves. A 30-90-day forecast will help you identify pressure in advance.
Can I use a short-term business loan to cover payroll?
Yes, some companies use short-term business funding to pay their bills when they’re facing cash-flow problems. This needs to be done with extreme caution, since payroll is a recurring payment. The repayment plan should be set up to align with customer payments and avoid adding additional strain to the next pay cycle.
Is it normal to have cash flow gaps with net 30 clients?
Absolutely, there is a risk of a cash flow gap with net 30 clients, particularly for businesses that pay suppliers or staff before receiving payment from their clients. It becomes a risk when multiple large invoices are due at once or when payment from one client is delayed.
What should I do if unpaid invoices are hurting cash flow?
Review invoice dates, follow up on invoices, determine which bills are critical, and forecast for the next 30 to 60 days. If the gap is short-term, small business funding for cash flow can help bridge it until payments are collected from customers.
