Any business’s lifeblood is its cash flow. Even a successful business might run into problems if money isn’t coming in and going out. And one major element that might interfere with cash flow is the aging of bills. Knowing how bill aging affects your cash flow and working capital is crucial, regardless of whether you work for a big company or manage a small one.

So, what exactly is bill ageing? How does it affect cash flow? And what can businesses do to manage it better? Let’s break it down.

What is Bill Ageing?

Bill ageing is a way to track how long it takes for a business to get paid by its customers or to pay its suppliers. It’s the timeline for invoices — both the money you’re waiting to receive (accounts receivable) and the money you owe (accounts payable).

It displays the length of time it takes for clients to pay their debts in receivables. It displays the length of time the company takes to pay its own bills for payables. Usually, these timescales fall into four categories: under 30 days, between 31 and 60 days, between 61 and 90 days, and above 90 days.

Bill ageing is important because it helps businesses understand where their cash is tied up and when they can expect it to be freed.

How Does Bill Ageing Affect Cash Flow?

Cash flow is simply the money moving in and out of a business. If you’re not getting paid on time, or if you’re not paying your suppliers on time, it can create serious problems. Here’s how bill ageing plays into that:

Receivables Ageing (Money You’re Owed): When customers take too long to pay their bills, cash flow suffers. Your money gets stuck in those unpaid invoices, making it hard to cover day-to-day expenses. The longer those invoices sit unpaid, the more cash you’re missing out on, and the less flexibility you have to keep things running smoothly.

Payables Ageing (Money You Owe): On the contrary, deferring payment to the business’s suppliers may seem like a short-term remedy to improve cash flow but not as a long-term aid. This brings late fines, strained relationships with suppliers, and losing out on prior payment incentives.

The Impact on Working Capital

Working capital is the difference between your current assets (like cash and receivables) and your current liabilities (like payables). Positive working capital shows that the business has more liquid assets to meet the short-term expenses, while on the other side, negative working capital brings more problems.

When bill ageing drags on, it can mess up your working capital in a big way:

Long Receivables Ageing: If your customers don’t pay on time, more of your working capital gets tied up in unpaid invoices. That means less cash on hand to cover bills, buy inventory, or invest in growth. Worst case? You might need to borrow money just to stay afloat.

Long Payables Ageing: Delaying payments to your suppliers can keep cash in your pocket temporarily. But if you stretch it too long, you risk hurting those supplier relationships. They might refuse to extend you credit, demand upfront payments, or even cut you off completely. Not to mention, it can hurt your reputation and credit score.

The Ripple Effect on Business

When bill ageing isn’t managed well, it can create a domino effect across the business:

Bad Debt Risk: When most of the receivables of the business reach beyond a reasonable time, the risk increases because the customer will never pay. This results in bad debt, which can harm the business’s financial health.

Supplier Trust Issues: When you keep delaying payments, suppliers might start to lose trust. They might not offer the same payment terms or discounts anymore, or worse, they might stop doing business with you altogether.

Cash Flow Problems: If you’re not getting paid on time but still have bills to cover, you could find yourself in a cash crunch. This could force you to take out loans or use credit, increasing your expenses with interest payments.

Operational Slowdowns: Without a steady cash flow, even simple things like buying stock or paying employees can become a challenge. This can disrupt business operations and slow growth.

How to Manage Bill Ageing

Managing bill ageing is key to keeping your cash flow healthy and your working capital in the green. Here are some tips:

Set Clear Credit Policies: Before offering credit to customers, make sure you have strict credit policies in place. Do background checks to ensure customers can pay, and set realistic payment terms.

Encourage Early Payments: Offering small discounts for early payments can push customers to pay their bills sooner. This gets cash in the door faster and improves cash flow.

Automate Invoices: Using software to send invoices automatically ensures you’re not delaying the process. The quicker you get invoices out, the sooner you’ll get paid.

Follow Up on Late Payments: Don’t be passive when customers miss payment deadlines. Send reminders, follow up, and if necessary, charge late fees to discourage repeat offenders.

Negotiate Better Terms: If you need more time to pay your suppliers, don’t just wait until the last minute. Negotiate longer payment terms upfront, and maintain good communication so suppliers know where you stand.
