The True Cost of Poor Procurement: How Bad Purchasing Decisions Impact the Whole Business

Procurement looks simple from the outside. Find what the business needs, find a supplier, negotiate the best price, place the order. Job done.

Except, as I've discovered throughout my career, the purchase order is usually where the interesting part begins.

I have worked across several very different businesses, each with a completely different approach to procurement. Some were driven primarily by budgets, some purchased almost entirely against confirmed customer orders, one operated under serious cash flow constraints, and my current business takes a much more data-led approach with proper stock buffers.

Looking back, each environment taught me something different. Most importantly, the cost of a purchasing decision is rarely limited to the figure on the purchase order. A decision that saves £5,000 on the cost of goods can easily cost the business £20,000 somewhere else. And sometimes, despite doing everything right, something will still go wrong, because supply chains occasionally enjoy reminding us who is really in charge.

When Cheaper Becomes More Expensive

Early in my career, I worked somewhere procurement decisions were largely driven by budget, supported by a bit of sales data.

One lesson came from a product selling extremely well. The sales curve was climbing, our sales manager had more budget available, and the logical decision seemed to be increasing our purchasing quantity from 1,000 units to 5,000. The maths looked excellent: greater volume meant lower manufacturing cost per unit, improving our margin and giving us room to stay competitively priced as more competitors entered the market. On paper, a great decision.

The problem was we'd bought into a prediction. We assumed the sales trend would keep climbing. It didn't. Competitors got more aggressive on price, and the market looked very different. We had thousands of units sitting in the warehouse, and the only way to encourage sales was to shrink our margins further, until we couldn't compete without effectively selling at a loss. Some competitors had either bought at a scale that gave them a serious cost advantage, or were prepared to sacrifice margin entirely, a game that's hard to win against.

The product didn't sell through anywhere near as fast as expected, so instead of enjoying that lower cost, we spent years paying to store inventory that wasn't moving. A wholesaler eventually bought the remainder in bulk at a heavy discount, useful for clearing the problem but nowhere near the success we'd imagined.

The lesson has stayed with me: the cheapest unit price isn't necessarily the cheapest purchase. The same trade-off applies to bulk buying decisions: storage, working capital, demand volatility, product lifecycle, competition, and the opportunity cost of cash tied up in inventory can outweigh a volume discount. 

There's a second lesson worth sitting with too: if you're buying heavily because you think you've spotted a trend, you may already be late. By the time a trend is obvious enough for everyone to trust it, competitors have probably spotted it as well.

The Other Extreme: Don't Buy Until You Have The Order

My next company operated completely differently, essentially a middleman business that didn't hold physical stock and purchased products against confirmed customer orders.

This worked well with established customers. We'd built relationships over years and offered something customers valued beyond the physical product: knowledge, quality assurance, and convenience. We took on much of the financial and supply chain risk, so the customer didn't have to worry about finding manufacturers, managing suppliers, or navigating international logistics. For a long-term customer, paying a premium made sense.

But the model got harder to defend as the market changed. Sites like Alibaba dramatically lowered the barrier to contacting Chinese manufacturers directly, so customers who once needed an intermediary could increasingly go straight to the source. Suddenly our margin wasn't simply paying for a useful service. To a new customer, it looked like an unnecessary extra cost.

For dropshipping sellers considering a product sourcing service, the question is what supplier evaluation, sampling, and factory coordination it provides beyond simply making introductions.

There was another problem too: lead time becomes part of your product. A customer needing £10,000 worth of goods might historically pay £12,000, because the extra £2,000 bought convenience, quality control, and someone else taking the risk. But if a competitor can source it directly for £9,000 and deliver faster, that traditional model becomes very hard to defend.

The lesson for me was that a procurement strategy can't exist in isolation from the wider market. A model that works brilliantly today can become a competitive disadvantage tomorrow.

When Cash Flow Dictates Procurement

The most stressful procurement environment I've experienced was an FMCG supplement business.

The company operated on relatively low margins and high volumes, so purchasing mattered enormously. Unfortunately, cash flow was also extremely tight, creating a vicious cycle: we needed ingredients to manufacture products, needed products to generate sales, but needed cash to buy the ingredients in the first place.

The business had more than 500 SKUs, but a small number generated a disproportionate share of revenue. My view was that we should prioritise those before expanding the range further. If 30 products generate around 70 percent of revenue, you probably shouldn't let those 30 run dry while keeping another 470 available.

Unfortunately, reality was more complicated. Three of our best sellers, Lion's Mane, Reishi, and Cordyceps, were heading towards an out-of-stock situation, and I'd been raising the need to purchase raw materials for months. Nobody was unaware that we needed them. The business simply didn't have the cash to buy everything it needed when it needed it. The accounts team had competing priorities, including overdue supplier payments and staff wages. Approval eventually came, but by then we were only two weeks from running out.

Then things got worse. Because payment had taken so long, the factory had allocated our production slot elsewhere, so once we paid, they had to manufacture our materials again. Red Sea shipping disruptions then forced the vessel onto a longer route, and once it reached the UK, it sat at customs for several more days. It felt at times like the supply chain had personally taken against us.

By the time the materials arrived, we'd been out of stock on all three products for around two months. Estimated lost sales were roughly £200,000, and that's where the true cost of procurement becomes obvious. It wasn't just the ingredients; it was lost sales, lost margin, frustrated customers, disrupted production planning, staff time, supplier relationships, and the knock-on effect on cash flow. A textbook case of the supply chain chasing its own tail: cash flow was too tight to buy enough stock, the lack of stock caused stockouts, and stockouts reduced sales, which made cash flow tighter still.

Meanwhile, the business kept investing heavily in marketing to generate demand, which wasn't a criticism of marketing, doing exactly its job. But there's little point generating demand for a product you can't supply.

Eventually, the financial pressure caught up with the business, leading to major cost-cutting and redundancies.

For small businesses, there's an important lesson here. When cash flow is tight, procurement shouldn't become an afterthought; it should become more strategic. Understand which products keep the lights on, prioritise the materials behind them, and calculate the financial impact of being out of stock rather than just the cost of buying the material. Spending £10,000 on stock can feel painful. Losing £50,000 in sales because you didn't spend it is far more painful, and far less visible until it's already happened. 

What Better Procurement Looks Like

My current role, as head of supply chain in a white label skincare business, has given me the chance to work in a much healthier procurement environment. All those years of watching things not go to plan turned out to be the best training I could have asked for.

We use data, forecasting, and experience together, typically holding three to six months of additional stock where risk and demand justify it. Forecasts are reviewed monthly, and stock is monitored closely. We don't just decide six months is the magic number for everything and forget about it. If a product sells more slowly, we reduce the buffer. If demand increases, we increase it.

Good procurement isn't about holding as much stock as possible. It's about holding the right stock, in the right place, for the right reason.

For dropshipping sellers that pre-stock products, warehouse storage and stock management also affect how that inventory buffer works in practice.

One useful discipline is setting a reorder point for key products using expected demand during the supplier's lead time plus a safety stock buffer that accounts for demand and replenishment uncertainty. It won't be perfect, but it beats a round figure someone picked because it felt sensible in a meeting.

That approach protected us from a problem I hit this summer. We'd purchased a raw material three months in advance. Despite chasing lead times, it never arrived; we were eventually told the shipment had been damaged and disposed of at a courier hub, not a sentence you want to hear about a delivery you've been tracking for weeks.

We'd done everything right: ordered early, monitored the order, stayed in contact with the supplier. And we still had to start the process again. The difference was that we had a six-month buffer, so the missing shipment was frustrating but didn't stop production. The buffer didn't prevent the supplier failure; it prevented the failure from becoming our customer's problem.

Procurement Can't Eliminate Risk, But It Can Manage It

One of the biggest lessons I've learned is that good procurement doesn't mean nothing ever goes wrong. Sometimes a supplier misses a deadline. Sometimes a shipment disappears. Sometimes customs holds something. Sometimes geopolitical events change a shipping route entirely. And sometimes a courier will apparently decide that your carefully planned three-month strategy belongs in the bin.

You can't control all of this. What you can control is how exposed your business is when it happens.

That's why we've increasingly looked at backup suppliers, even for unusual raw materials. It used to be tempting to think, we hardly ever buy this, so do we really need another supplier for it? The better question is, what happens if our only supplier suddenly can't provide it? If the honest answer is that a whole production line stops for months, a second supplier looks a lot more attractive, even if it costs a little more to keep that relationship warm. The cost of switching suppliers should also be part of that contingency calculation.

It's also worth finance and procurement having an honest conversation about how the two interact. In the FMCG business, the accounts team weren't careless; they were juggling genuine competing demands, but nobody had modelled what a stockout on the best sellers would cost. Had that £200,000 figure been shared before the decision, the conversation about which payment to prioritise might have gone differently. A small contingency reserve, or trade credit insurance, is worth considering for businesses operating close to the edge on cash flow, since it turns a scramble into a plan.

There's a human cost too, one that doesn't show up on any spreadsheet. Constantly firefighting stock shortages is exhausting, and pushes everyone into reactive, short-term decisions when longer-term thinking is needed most. A business that keeps its people out of permanent crisis mode usually makes better purchasing decisions.

The Real Cost Of Procurement

After working across these businesses, I no longer think of procurement as simply getting the best price. The real job is balancing price, quality, availability, lead time, cash flow, demand, storage, supplier reliability, and risk, all at once, usually while somebody upstairs is asking why the numbers haven't improved yet.

A £1 cheaper component isn't necessarily better if it arrives three weeks late. Buying 5,000 units instead of 1,000 isn't necessarily clever if you only sell 1,500. Holding almost no stock isn't necessarily efficient if one delayed shipment can stop your best seller. And holding six months of every ingredient isn't necessarily prudent if half of them belong to products that barely sell.

Procurement sits at the intersection of almost every part of a business. Sales needs stock to fulfil orders. Production needs materials to manufacture. Finance needs working capital under control. Operations needs reliable planning. Marketing needs products that can actually be supplied. And customers don't care whose fault the shortage was. They just know the product they wanted isn't available.

That's probably the most important lesson I've taken from all of this. Good procurement isn't about spending the least money. It's about making sure every pound spent supports the wider business, whether that means buying less, buying more, paying a higher price for reliability, holding six months of stock, or keeping a backup supplier quietly in reserve for an ingredient you desperately hope you'll never need.

Because ultimately, the true cost of poor procurement isn't found on the purchase order. It's found in the problems that come afterwards.
