Answer
What should you do if a supplier lets you down?
Tell your customer it has moved without naming the supplier, then decide whether this was an incident or a pattern.
Communicate the impact to your customer immediately without attributing it, solve their problem, and then assess the supplier separately. Naming the supplier in the first conversation transfers no blame and signals a business that does not control its own delivery.
When a supplier fails, two problems exist and they should be handled separately. Your customer has a problem that is now yours regardless of cause, and you have a supplier problem that is a commercial matter for another day. Merging them — explaining the supplier situation to the customer as though it settles anything — solves neither and damages your position.
From the customer's side, the distinction does not exist. They contracted with you, the outcome is late or wrong, and the identity of whoever caused it is not information they can use. Naming the supplier feels like context and lands as an excuse, and worse, it suggests a business that does not control its own delivery. The useful communication states the impact, the new position and what is being done, in the same shape as any other delay.
Solving the customer's problem sometimes means going around the supplier at your own cost, and that decision should be made on the value of the relationship rather than on the fairness of the situation. Sourcing elsewhere at a worse price, doing part of the work differently, or absorbing a cost you did not cause are all reasonable where the customer relationship is worth more than the difference. Recovering that from the supplier is a separate conversation that does not need to happen first.
The supplier conversation should happen and it should be specific. What was agreed, what happened, what it cost you, and what needs to be different. A supplier who acknowledges it and changes something is worth keeping. One who does not, or who has now done this more than once, is a risk you are carrying on behalf of your customers, and continuing with them is a decision rather than an accident.
The distinction that matters is between an incident and a pattern, and it requires the records to tell them apart. A supplier who fails once in three years is a supplier; one who fails quarterly is a structural exposure. Businesses without a record of these events routinely tolerate a pattern because each instance is forgiven individually, which is how a single supplier ends up causing a substantial share of a business's customer problems.
The structural protection is not loyalty but alternatives. A second source identified before it is needed — even one you rarely use — converts a supplier failure from a crisis into an inconvenience, and it changes the tenor of every conversation with the first supplier. Businesses with one source for anything critical have accepted a dependency, and the time to notice that is not the week it fails.
Your customer bought from you, so a supplier failing is your failure with an explanation attached, and the explanation interests nobody but you.

Should we ever tell the customer it was a supplier?
Occasionally, briefly, and after the situation is resolved rather than as the explanation for it. Where a customer asks directly, an honest short answer is better than evasion. What does not work is leading with it, because at the moment they are told the outcome has changed, the only thing they can act on is what happens next.
How do we recover the cost from a supplier?
With a record of what was agreed and what it cost, presented as a specific claim rather than a complaint. Suppliers respond to a documented figure far more readily than to an account of the inconvenience. Where the agreement did not specify delivery obligations, that is a lesson for the next agreement rather than an argument you are likely to win.

| Kind | Claim | Check it against |

| Buying behaviour | A customer contracted with the business rather than its supplier, so the identity of the party that caused a failure is not information they can act on, and naming it reads as an excuse and as an absence of control over delivery. | Customer responses to explanations naming a supplier against those stating impact and remedy only. |
| Procurement | Going around a failed supplier at the business's own cost should be decided on the value of the customer relationship rather than the fairness of the situation, with recovery pursued separately afterwards. | The customer's value against the incremental cost of the alternative source for that occasion. |
| Workflow | Distinguishing an incident from a pattern requires a record of supplier failures, and without one each instance is forgiven individually, which allows a single supplier to cause a substantial share of customer problems. | A log of supplier failures over a year, grouped by supplier. |
| Procurement | An identified second source, even one rarely used, converts a supplier failure from a crisis into an inconvenience and changes the terms of every conversation with the primary supplier. | Whether a qualified alternative exists and has been used at least once for each critical input. |
