Most businesses set their payment terms once and never look at them again. Customers pay on thirty days because they always have. Suppliers are paid on whatever terms were agreed when the relationship began. The terms feel like a fixed feature of the business rather than a decision, and because they sit quietly in the background, almost no one revisits them. That habit is expensive.
Payment terms are one of the largest cash levers an owner controls, and one of the least used. The gap between when you pay for something and when you get paid for it is the cash cycle, and the length of that cycle decides how much working capital the business has to fund out of its own pocket. Shorten the cycle and cash appears that was always there, just trapped in the timing.
The Cash Cycle Is the Number Worth Mapping
The cash cycle runs from the day you pay a supplier to the day your customer pays you. If you pay suppliers in fourteen days and collect from customers in fifty, the business is funding thirty-six days of trading from its own resources on every dollar of activity. As the business grows, that funding requirement grows with it, which is why fast-growing businesses so often feel cash-starved despite being profitable. They are financing a longer and longer cash cycle out of their own pocket.
For businesses that hold stock, the cycle is longer still, because cash goes out when the stock is bought and does not come back until the finished goods are sold and the invoice is paid. Inventory sitting on a shelf is cash the business has already spent, waiting to be earned back. Mapping the cycle makes the cost visible. Once you can see how many days of your own cash are tied up in the gap, the levers become obvious. Collect a little faster, pay a little slower where the relationship allows, hold a little less stock where you safely can, and the trapped cash releases. None of this is about squeezing anyone. It is about bringing the terms back into balance after years of them drifting unexamined.
Both Directions Matter, and Neither Needs Strain
On the customer side, the question is not just the headline terms but whether they are actually honoured. Terms of thirty days mean little if the average collection runs to fifty. Tightening invoicing, removing the friction that delays payment, and following up consistently often shortens collection without ever changing the stated terms or straining a relationship. Most customers pay late because the process let them, not because they intended to. The friction is usually mundane and entirely fixable: an invoice that goes out a week after the work is done, that lands in the wrong inbox, that lacks a purchase order number the client’s system demands, or that offers no easy way to pay. Each of those adds days, and none of them is about the customer being difficult.
On the supplier side, the lever is using the terms you have rather than paying early out of habit. Many businesses pay suppliers well before they need to, giving away cash for no benefit. Aligning payment to the agreed terms, and renegotiating terms where there is genuine room, holds onto that cash without damaging supply. A working capital unlock maps where cash is trapped across debtors, supplier terms and the cycle as a whole, and typically finds a meaningful share of revenue sitting in the timing. The principles behind it are set out in our guide to cash flow discipline, which is worth reading before you touch a single term.
Cash That Was Always Yours
The cash released by tightening the cycle is not new money. It is cash that already belonged to the business, sitting in the gap between paying and being paid. That is what makes this such a high-return exercise. There is no sale to win, no cost to cut, no product to change. There is only timing to bring back into balance, and the cash that timing was holding.
The discipline matters most precisely when the business is doing well. A struggling business watches its cash closely out of necessity, but a growing one is easy to read as healthy right up to the point where the cash cycle quietly outruns the bank balance. Strong sales feel like proof that everything is working, yet every new order lengthens the gap that has to be funded, and a business can grow itself into a cash squeeze while the profit and loss looks better than ever. That is why the owners who watch the cycle through the good periods rarely get caught by it. They treat the released cash as the first source of funding for the next stage, before they consider anything external.
For a business carrying any growth or any seasonality, getting the cash cycle right is often the difference between funding the next stage from your own working capital and reaching for a facility you did not need. It is quiet work, easy to defer, and it pays back faster than almost anything else on an owner’s list. If the business feels tighter than the profit suggests it should, the payment terms are usually the first place to look, and that is the kind of review we help owners run.

Frequently asked questions
What is the cash cycle and why does it matter?
The cash cycle is the time between paying a supplier and being paid by your customer. If you pay in fourteen days and collect in fifty, you are funding thirty-six days of trading from your own resources on every dollar of activity. The longer the cycle, the more working capital the business has to fund itself. As you grow, that requirement grows too, which is why profitable businesses can still feel cash-starved.
How can I free up working capital without raising more finance?
Shorten the cash cycle. Collect a little faster and pay a little slower where the relationship allows, and cash that was trapped in the timing releases. A working capital unlock maps where cash is tied up across debtors, supplier terms and the cycle as a whole, and typically finds a meaningful share of revenue sitting in timing. The cash released is not new money. It already belonged to the business, which is what makes it such a high-return exercise.
How do I collect from customers faster without straining relationships?
Most customers pay late because the process let them, not because they intended to. Tightening invoicing, removing the friction that delays payment and following up consistently often shortens collection without changing the stated terms. Stated terms of thirty days mean little if average collection runs to fifty, so the gain is in closing that gap. Done well, it improves cash flow while keeping the relationship intact, because you are enforcing what was already agreed.
Should I always pay suppliers as late as possible?
No. The lever is using the terms you have rather than paying early out of habit, not stretching suppliers to breaking point. Many businesses pay well before they need to, giving away cash for no benefit. Aligning payment to the agreed terms holds onto that cash without damaging supply, and there is sometimes genuine room to renegotiate. The aim is balance, not strain. A reliable supply chain is worth more than a few extra days of cash.
Why do growing businesses often feel short of cash despite profit?
Because growth lengthens the funding requirement of the cash cycle. Every extra dollar of activity has to fund the gap between paying suppliers and being paid by customers, so a longer cycle means more of your own cash is tied up as you grow. The profit is real, but it is locked in debtors and stock rather than sitting in the bank. Mapping and tightening the cycle is often how growth gets funded without reaching for a facility. Our cash flow discipline guide covers this.
How often should a business review its payment terms?
More often than most do, which is almost never. Terms tend to be set once and left, drifting unexamined for years while the business and its growth change around them. Reviewing the cash cycle at least annually, and after any significant change in size or seasonality, keeps the terms working for you rather than against you. It is quiet work that is easy to defer, but it pays back faster than almost anything else on an owner’s list.
