PO acceptance and short supply: protecting your fill rate
Accepting a purchase order you cannot fully supply feels cooperative. It is the fastest way to damage the score that decides how much you get ordered next time.
- Fill rate is scored on what you accepted, not what you were asked for. Accepting optimistically is what hurts you.
- Confirm against committed stock, not against expected production or stock in transit.
- A clean partial acceptance almost always beats a full acceptance you cannot honour.
- Repeated shortfalls quietly reduce future order quantities, which is harder to reverse than a single miss.
Every brand supplying a marketplace vendor programme, a modern trade chain or a quick commerce platform runs into the same moment. A purchase order arrives for more units than you can comfortably supply. The commercial instinct is to accept it in full, because rejecting demand feels like turning down revenue and disappointing a buyer you want to keep happy.
That instinct is expensive, and understanding exactly why changes how the decision gets made.
The denominator is your own commitment
Fill rate scoring compares what you delivered against what you confirmed, inside the required window. The number you are measured against is the one you chose.
Consider the same physical reality two ways. A PO arrives for 10,000 units and you can ship 7,000. Accept 10,000 and ship 7,000, and you have recorded a 70 percent fill rate. Accept 7,000 and ship 7,000, and you have recorded 100 percent. The customer received identical goods on an identical date. Your scorecard reads completely differently.
Once this is clear, optimistic acceptance stops looking cooperative and starts looking like a self inflicted wound.
Why the score matters more than the single order
If the consequence of a poor fill rate were only a number on a dashboard, this would be a minor topic. It is not.
Fill rate feeds the buyer’s planning assumptions. A supplier who reliably delivers what they confirm gets ordered more, gets considered for promotional volumes, and gets the benefit of the doubt in a capacity squeeze. A supplier who regularly falls short gets ordered defensively, in smaller quantities, more often.
That reduction is gradual and rarely announced. Nobody sends an email explaining that your order quantities are being trimmed because of reliability. It simply happens, and by the time a brand notices that volumes have drifted down, the cause is several months in the past and difficult to argue with.
Confirm against committed stock only
The operational discipline that prevents most of this is narrow and unglamorous: confirm only against stock you physically hold and have not promised elsewhere.
Not stock in production. Not stock in transit. Not stock at a port. Not stock a supplier has assured you will arrive. Each of those has a probability attached, and accepting against them means you are gambling with a score that takes months to repair.
This requires knowing your true available to promise position across all channels, which is where many brands are genuinely weak. If your marketplace team and your retail team can both see the same 5,000 units and both commit them, you will discover the conflict at the worst possible moment. A single allocation view is the precondition for confirming anything responsibly.
Communicate the shortfall before it becomes a discovery
When you cannot fully supply, the difference between a manageable event and a damaged relationship is almost entirely about timing.
A buyer told early, with a specific revised quantity and a firm date, can adjust their plan, brief their stores, change a promotion or source elsewhere. The same buyer who finds out when the shipment lands has already built a stock position and possibly a promotion around a number you gave them.
Be specific rather than apologetic. What quantity, by what date, with what certainty. Vague reassurance is worse than a clear smaller number, because it prevents them from planning around you.
Prioritising when you cannot serve everyone
Short supply forces allocation decisions across channels, and making them by whoever asks loudest is common and wrong.
A more defensible approach weighs three things. The cost of missing, which differs sharply: a scored vendor relationship where a miss reduces future orders is more expensive than a channel where it does not. The contribution per unit in each channel. And the strategic position of the relationship, since a partner you are trying to grow with may justify protection over one you are winding down.
Decide it deliberately and record the reasoning. Allocation decisions made under pressure without a rule become precedents, and the next shortage gets argued on the basis of what happened last time rather than on what is right.
Fix the forecast, not just the acceptance
Careful acceptance is damage control. Persistent short supply means the planning upstream is wrong.
Two causes dominate in Indian consumer brands. Production lead times that are longer than the ordering cycle assumes, so you are always reacting rather than anticipating. And demand that is genuinely lumpy because platforms run promotions with limited notice, which makes steady state forecasting inadequate.
The second is addressable commercially. Ask your platform contacts for promotional calendars further ahead, and treat a request for a promotion at short notice as a request you are entitled to decline if you cannot supply it. Agreeing to a promotion you cannot stock produces the worst possible combination: a demand spike, an out of stock listing, a damaged fill rate, and a buyer who is annoyed anyway.
