The tender evaluation had four columns: price per kilogram, absorption ratio, delivery lead time, and packaging format. Price carried 40 per cent of the score. Lead time carried 10. The winning bid quoted six weeks from purchase order to delivery, which scored well enough, and eleven weeks later a 400-bed hospital was issuing absorbent pads to two wards because the powder had not arrived.
That is not a story about a bad supplier. It is a story about a scoring model that treats lead time as a convenience rather than a constraint, and about what happens to a ward when a consumable runs dry.
The hospital held roughly five weeks of stock when the contract started, a figure nobody had written down because the previous supplier delivered in ten days and replenishment was assumed. The new supplier shipped from a plant in another country, with a production slot booked only after the order was confirmed. Week six came and went with a customs query on the SDS paperwork. Week seven brought a partial delivery of the wrong pack size, 500 g jars instead of the 2.5 kg tubs specified, which the stores team rejected.
By week eight the sluice rooms on two wards had run out. Staff fell back on pads, which cost more per litre of urine handled and add volume to the clinical waste stream. The hospital estimated the eight-week gap cost about £4,300 in pads and staff time, against a contract saving of roughly £1,900. The cheapest bid lost money.
Three clauses would have prevented it. First, a stock-holding obligation: the supplier holds a stated quantity in a named warehouse within the delivery region, with the right to audit. Second, a call-off mechanism with a fixed maximum response time, so the hospital is not ordering a full pallet to get a single case. Third, a substitution clause that names the pack sizes that may be shipped without prior approval, and requires written notice for anything else.
The fourth clause is less obvious but matters just as much: a defined behaviour at end of contract. If a trust switches supplier with four weeks of stock left, the outgoing supplier should buy back unopened stock or the trust should be allowed to run it down. Without that, procurement delays the switch, the old product sits in stores past its useful life, and the new contract starts with an argument.
Buyers compare cost per kilogram because it is easy to put in a spreadsheet. The number that determines budget impact is cost per litre of urine handled in a real shift, including the labour of opening packaging, the volume added to the waste stream, and the frequency of collection. A product at £9/kg dosed at 1.2 g per litre costs less per litre than one at £7/kg dosed at 1.9 g per litre, and the cheaper-looking line is the expensive one.
Then there is the invisible cost of the fallback. Pads, in a hospital setting, are not just more expensive per litre: they change the waste route, they add weight to domestic-type waste, and they require a bin that staff must locate at 03:00. A stock-out does not pause the problem it was meant to solve.
Ask for the supplier’s last twelve months of on-time delivery performance, not a promise. Ask for the production lead time from order confirmation to dispatch, separately from shipping time, because the two fail in different ways. And ask what quantity is held in stock in your region today, with a name and a location attached.
If a bidder cannot answer the third question, the price is not comparable to one that can. The SAP powder product range page is a reasonable place to start matching grades to a ward’s actual urine volumes, but the lead-time conversation has to happen with the supplier’s operations team, not their sales deck.
