Does the supplier need access to our systems?

They need the data, not necessarily the systems. A regular file of consumption and stock positions is usually enough, and it avoids the access questions that come with opening an internal system to an external party.

What stops a supplier from over-supplying?

Agreed stock limits and a measure that penalises excess as well as shortage. If the only measure is availability, the rational supplier keeps you generously stocked at your expense, which is a design fault rather than misconduct.

Can the arrangement be reversed if it disappoints?

Yes, and the exit should be written down: notice period, treatment of stock in place, and how ordering responsibility transfers back. Reverting is far easier when the buyer kept the capability to plan those items rather than dismantling it.

Supplier-managed stock or your own ordering: who decides quantities

In one arrangement the buyer decides what to order and when; in the other the supplier watches consumption and decides for them. The mechanics are straightforward and the governance is not, because handing over the decision without handing over accountability produces an arrangement where nobody quite owns availability. Getting the measures and the data right matters more than the concept.

Comparison criteria

Criteria are stated explicitly and neither option is declared a winner: which one fits depends on the constraint that binds hardest in your operation.

Criterion	Vendor-managed inventory	Buyer-ordered replenishment
Who decides quantity and timing	The supplier, working to agreed limits and to consumption data the buyer provides.	The buyer, using their own policy, forecast and judgement.
Data requirement	Regular, accurate consumption and stock data must flow to the supplier, or the decisions are made blind.	Data stays internal, so poor accuracy hurts only your own decisions.
Ownership of the goods	Varies by agreement: stock may remain the supplier's until consumed, which shifts working capital.	The buyer owns stock from delivery and carries it on the balance sheet.
Administrative load	Fewer purchase orders and less expediting, replaced by exception management and periodic review.	Continuous ordering, chasing and reconciliation, absorbing buyer time.
Accountability for availability	The supplier can be held to an availability measure, since they control the decision.	Sits with the buyer, who cannot fairly blame the supplier for a quantity the buyer chose.
Supplier planning	Visibility of real consumption lets the supplier plan production and smooth their own operation.	The supplier sees orders rather than demand, which amplifies variation up the chain.
Risk of the arrangement drifting	Suppliers can over-supply to protect their measure, leaving the buyer holding more than needed.	Buyers can under-order to protect cash, then expedite at a premium when demand appears.

Choose Vendor-managed inventory when

Consumption is steady and can be reported accurately and frequently to the supplier
The relationship is long-term and both sides are prepared to share real data rather than forecasts
Buyer time spent on routine ordering is significant and better used elsewhere
The supplier has the systems and discipline to manage replenishment properly rather than to ship on a schedule

Choose Buyer-ordered replenishment when

Demand is erratic, or your consumption data is not accurate enough to be acted on by anyone
The supplier is remote, transactional, or unwilling to commit to an availability measure
Items come from many suppliers in small quantities, so the coordination cost exceeds the benefit
Commercial sensitivity makes sharing consumption data with a supplier unattractive

The decision moves, the accountability must move with it

Supplier-managed arrangements fail when the buyer transfers the ordering work but keeps blaming the supplier for outcomes without measuring them. Agree in advance what availability standard applies, what stock range is acceptable, how consumption is reported and how quickly the supplier must react to a change. Equally, the buyer retains obligations: accurate data, notice of promotions or design changes, and honest visibility of anything that will move demand. Where either side withholds, the arrangement degrades into a scheduled delivery programme with extra paperwork.

Ownership of stock is a separate question

Who manages replenishment and who owns the goods are often confused. The supplier can manage quantities while the buyer owns everything on receipt, or the stock can remain the supplier's until it is consumed. Each has different effects on working capital, obsolescence risk and accounting treatment. Settle it explicitly, including what happens to slow-moving or obsolete units, who bears the loss when a specification changes, and how stock is counted and reconciled. Those clauses are where consignment arrangements are won or lost, long after the operational design has been agreed.

Start narrow and prove it

The sensible pilot covers a small group of stable, high-volume lines with one capable supplier. That keeps the data burden manageable and produces evidence within a reasonable period: availability, stock held, order lines removed and any exceptions that had to be handled manually. Extend only where the evidence supports it. Businesses that roll the model across a whole category at once usually discover that half the lines were too irregular for it, and the resulting failures are attributed to the concept rather than to the selection.
