Split procurement looks cheaper on the spreadsheet: each position is bought from whoever quoted the lowest price for it. The cost that does not appear on that spreadsheet is coordination — and it is usually paid by the person who has the least time to spare.
Where split procurement actually breaks
- Nobody owns the result. Each supplier is responsible for their own position. The question of whether the facility works as a whole belongs to no one — in practice, to you.
- Deliveries arrive out of step. Equipment that must be installed together arrives weeks apart, and the site waits for the last item rather than the first.
- Interfaces fall between suppliers. The power supply, the connections, the mounting — every gap between two contracts is a place where each side can reasonably say it was not theirs.
- Faults become an investigation. When something does not work, the first task is establishing whose equipment caused it, and each supplier has an interest in the answer being someone else.
- Administration multiplies. Ten contracts, ten sets of documents, ten deliveries to accept, ten warranty conversations — all of it staff time that no one costed.
What one contract changes
A single supplier carries the result rather than the positions. That means one delivery schedule aligned to the construction programme, one acceptance process, one warranty conversation, and one party who cannot answer a fault by pointing at someone else.
It also changes the quality of the specification itself: a supplier responsible for the whole set has an interest in the items fitting each other — the generator sized to the actual load, the transfer switch matched to the generator, the pump matched to the pipework. Split procurement optimises each line and no one checks the sum.
How to cost a package without overpaying
The reasonable objection to a single supplier is that one price is harder to verify than ten. The answer is to require the package to be quoted line by line: each position priced separately, plus works, delivery and commissioning shown explicitly.
That gives a set you can compare against the market position by position, while still buying it as one responsibility. A supplier unwilling to break the package down is asking for trust on the wrong terms.
Compare the total honestly: against the split alternative including delivery for each supplier, installation, the interfaces nobody quoted, and the staff time spent coordinating it.
When splitting is still the right call
- A large share of the budget sits in one highly specialised item that a general supplier will simply resell.
- Part of the equipment is already standardised across your facilities and the supplier is fixed for good reasons.
- Procurement rules require separate lots — a constraint, not a choice.
- The deliveries genuinely do not interact: separate buildings, separate stages, separate systems.
The rule of thumb: equipment that must work together is worth buying together. Equipment that merely happens to be bought at the same time is not.
We supply facilities as a complete set — equipment, delivery, installation and commissioning under one contract, quoted line by line — and we carry the result rather than the positions. Send the equipment list, or simply describe the facility and its stage, and our engineers will assemble the package.
