When cash flow tightens, the usual reflex is to look for bank financing. Before that, there is a cheaper source that is almost always unexplored: the terms you pay your suppliers on. The difference between paying at 30 and paying at 60 days permanently frees up a month of purchases in working capital.
What separates a well-run negotiation from a damaged relationship is almost entirely method.
Before negotiating, know who you're negotiating with
Not every supplier carries the same weight or the same room to manoeuvre. It is worth splitting them into three groups:
- Strategic: hard to replace, with direct impact on operations. Here the priority is the relationship, not the term.
- High-volume but replaceable: this is where the real negotiating leverage sits.
- Small and recurring: negotiating terms is not worth the effort; automating payment and stopping giving them attention is.
At most SMEs, four or five suppliers account for most of what they buy. That is where the conversation should be focused.
What makes a request acceptable
A supplier accepts extended terms when they get something in return. In order of effectiveness:
- Predictability. "We'll move to paying at 60 days, but always on the 10th, no exceptions." A supplier prefers a certain 60 days to a 30 days that is sometimes 45.
- Volume or commitment. Concentrating purchases with one supplier in exchange for terms.
- Advance information. Giving visibility on future needs is worth money to whoever has to manage stock.
What does not work is asking for more time after payments have already been missed. By then it is not a negotiation any more, it is managing a default, and terms get worse instead of better.
The sum almost nobody does
Many suppliers offer an early-payment discount — typically 2% for paying at 10 days instead of 30. That sounds small. It isn't.
Two percent for paying 20 days early works out to an annualised cost of around 36%. Put the other way round: if the company has spare cash, taking that discount pays off far more than any investment would. And if it doesn't have spare cash, declining it is the right call — but it should be a conscious decision, not a habit.
Paying on time is a competitive advantage
There is a reversal worth noting: in an economy where late payment is the norm, the company that pays with absolute punctuality gains negotiating power. It gets better terms, better prices, and priority when supply is tight.
It is the same principle that applies on the other side, in collections: predictability is worth more than occasional generosity.
The final mistake
Extending terms without updating the cash flow forecast creates a false sense of slack for a month or two. The commitment has not disappeared, it has just moved date. If the relief gets used to grow overhead instead of stabilising operations, the problem comes back bigger.
