Extending payment terms is one of the most familiar tools in working capital management.
From a buyer perspective, the logic is straightforward: preserve cash, improve predictability, maintain control. Terms are negotiated, agreed, and applied consistently. Suppliers continue to deliver. Payments go out later than they used to.
On the surface, it looks clean.
What’s less visible is what happens on the other side of those terms once the invoice is approved and sent into the waiting period.
Because suppliers rarely just wait.
The assumption buyers make about payment terms — and why it rarely holds
When payment terms are extended, it’s often assumed suppliers absorb the impact.
Sometimes that’s framed as efficiency. Sometimes as commercial reality. Often it’s simply left unexplored. The reasoning is understandable: suppliers accepted the terms, so the risk must sit with them.
In practice, however, suppliers don’t absorb timing gaps. They solve them.
And they do so using funding tools that buyers rarely see — or price internally at the same level.
How suppliers actually fund extended payment terms
Once terms stretch and cash inflow slows, suppliers act rationally. They bridge the gap using whatever options are available to them.
Common routes include:
Overdrafts and revolving credit
Often the fastest solution, and frequently the most expensive. Rates fluctuate. Limits tighten. Balances linger longer than intended.
Invoice factoring and selective invoice finance
Used to accelerate cash tied up in receivables. Sometimes applied across a whole book, sometimes invoice by invoice. Admin heavy, fee-based, and largely invisible to buyers.
Supply chain finance
Where programmes exist, suppliers may access early payment using buyer credit strength — usually through a bank-led structure that still has cost, conditions, and limited flexibility.
None of this is unusual. It’s how suppliers adapt when timing pressure increases.
What’s notable is not that it happens — but that it happens out of view.
The funding gap finance leaders instinctively recognise
Most finance leaders don’t need an APR comparison to feel the mismatch.
Suppliers are often funding themselves at rates buyers would never approve internally for their own balance sheet. Short term facilities priced higher than corporate credit. Fees that would raise questions in any treasury discussion.
Yet those costs sit outside buyer visibility — even though they’re being incurred as a direct response to buyer set terms.
The asymmetry is intuitive. The consequences are not always immediate.
Why the cost never stays with the supplier
Supplier funding costs rarely remain isolated.
They find their way back into the system — just not in a neat, line item way.
Over time, those costs reappear through:
- Pricing behaviour — less flexibility, fewer concessions, incremental increases that are hard to isolate
- Relationship strain — reduced goodwill, slower responses, less tolerance when issues arise
- Supply risk — lower prioritisation, reduced resilience during disruption, fragility under stress
The original payment terms extension still delivers cash benefit on paper. But the economic pressure it creates doesn’t disappear. It re enters later, in forms that are harder to measure and harder to reverse.

Why finance teams rarely see this happening
There’s a reason this dynamic often goes untracked.
Supplier funding choices:
- don’t appear in buyer ERP or AP systems
- aren’t typically disclosed in negotiations
- surface long after payment terms are changed
The symptoms reach finance indirectly — through procurement conversations, supplier escalations, price pressures, or operational interruptions.
By then, the original decision is several steps removed.
Finance ends up managing the consequences of behaviour that originated elsewhere — without visibility into the mechanism behind it.
Influence without visibility creates risk
Buyers control payment terms. Suppliers control how they survive them.
Both are acting rationally.
The issue isn’t intent. It’s asymmetry.
When buyers influence cash timing but can’t see how suppliers respond financially, cost and risk move through the supply chain without governance.
That’s when working capital decisions start producing outcomes finance didn’t explicitly choose — but still has to absorb.
Rethinking payment terms as a shared pressure point
Payment terms aren’t just commercial agreements. They’re pressure distribution mechanisms.
They determine not only when cash leaves the buyer, but where funding stress lands in the system. When that stress is left unmanaged, suppliers solve it independently — often expensively.
This isn’t about reversing terms or avoiding discipline. It’s about recognising that extended terms don’t eliminate cost. They move it.
And moved costs tend to return — just later, and less transparently.
The takeaway
Suppliers don’t absorb extended payment terms. They fund around them.
Through overdrafts, factoring, or structured programmes, timing pressure is resolved — at a cost buyers would rarely choose for themselves.
That cost doesn’t disappear. It comes back through pricing, relationships, and supply resilience.
The question for finance isn’t whether suppliers are solving the problem.
It’s whether you want visibility into how — and influence over where the consequences ultimately land.
Engagement doesn’t require commitment.
Speaking with B2BE is simply a way to assess whether supplier funding costs are creating consequences you’d rather manage deliberately.
