Dear Sir / Madam,
I am writing to tell you, before you have to ask, that order [order no.] will not arrive on the date we promised.
The reason is: [reason]. The revised delivery date is [date], and that date has been checked rather than estimated.
If the new date does not work for you, tell me and we will look at part-shipping or cancelling without penalty.
What is a Delivery Delay Letter?
A delivery delay notice tells a customer their order will not arrive when you said, gives the new date, and says what you are doing about it. The delay is usually forgivable; discovering it from a tracking page on the due date is not. A letter sent as soon as you know converts a broken promise into a managed expectation, and it is often the difference between a rescheduled order and a cancelled one.
Manufacturers, wholesalers, online retailers, furniture and appliance sellers, builders' merchants, printers and equipment suppliers all send these — for stock shortages, supplier failures, freight and customs delays, production faults, weather and port congestion. Customer service teams send the routine ones; account managers send them where the customer is large or the delay has knock-on effects at their end. In B2B supply the notice matters more, because your customer may have promised the goods onward and needs the new date to manage their own commitment.
Legal consequences differ by jurisdiction and by whether the buyer is a consumer or a business. Consumer law in the UK and EU gives buyers rights where goods are not delivered within an agreed period or a reasonable time, including the right to cancel and receive a refund in defined cases; Australian Consumer Law, Canadian provincial rules, Indian consumer protection legislation and US state statutes each set their own positions. Business contracts turn on the terms you agreed: whether time is of the essence, whether there is a liquidated damages clause, and what your force majeure clause covers. Check your contract and the consumer law that applies before promising anything.
A delay notice is not a variation of the contract. Telling a customer the new date does not, by itself, extend the delivery obligation you agreed — that requires their agreement, and in some cases their consent has to be explicit. It is also not a defence to a liquidated damages or late delivery clause. And it should not be used to reset expectations with a date you are not confident of: a second slipped date does more harm than the first, because the customer stops believing any date you give and starts planning around your failure.

How to write a Delivery Delay Letter
Send it the moment you know
The value of the notice decays by the hour. Send as soon as the delay is confirmed internally, even if you cannot yet give a firm new date — an interim message saying you have a problem and will confirm the revised date by Thursday is far better than silence. Customers who find out late assume you knew and said nothing, which is the version that damages the relationship.
Identify the order precisely
Quote your order number, their purchase order reference, the items and quantities affected, the original delivery date and the site. If only part of the order is delayed, say exactly which lines and confirm the rest is unaffected. A customer with fifteen open orders needs to know in one line which one this concerns and whether they should stop planning around it.
Give a specific new date and your confidence
A dated commitment beats a range, and a range beats ‘as soon as possible’. If the date depends on something outside your control — a vessel arrival, a supplier's confirmed slot — say so and give the date you will next update them. Do not pad the date to be safe and then deliver early as a favour; buyers plan against the date you give and an unexpectedly early delivery causes its own problems.
Explain the cause briefly and honestly
Two sentences: the component supplier missed their shipment, the container was held at customs, a machine failed and the part is on order. Enough for the customer to judge whether the new date is credible, without a chapter of internal detail. If the cause is something you could have foreseen, do not dress it up as an act of God — buyers can usually tell, and the credibility cost is worse than the admission.
Offer the options and name a contact
Set out what you can do: part-ship what is available, substitute an equivalent specification, arrange expedited freight at your cost, hold the whole order, or cancel with a full refund. Say which you recommend and what each does to the date. Give a named person, a direct number and a deadline for their decision, and confirm whatever they choose in writing the same day.
Common mistakes
- Waiting until the delivery date passes, so the customer discovers the delay from a tracking page rather than from you.
- Giving a vague new timeframe such as ‘shortly’ or ‘in the coming weeks’, which the customer cannot plan around and will chase you about.
- Quoting a second date you are not confident of, which destroys trust in every date you give afterwards.
- Assuming the notice varies the contract, when the delivery obligation and any late delivery remedy still stand unless the customer agrees otherwise.
- Offering no options, so a customer who could have taken a part-shipment or a substitute cancels the whole order instead.
Frequently asked questions
How do you tell a customer their order is delayed?
Contact them as soon as you know, identify the exact order and affected lines, give a specific revised date and say how confident you are in it, explain the cause in a sentence or two, and offer practical options — part shipment, substitution, expedited freight, hold or cancel. Name a person they can reply to and confirm whatever they decide in writing the same day.
What are a customer's rights if delivery is late?
That depends on whether they are a consumer or a business and where they are. Consumer law in many jurisdictions gives rights to cancel and obtain a refund where goods are not delivered within an agreed period or a reasonable time, sometimes after giving a further opportunity. Business contracts turn on the agreed terms, including whether time is of the essence. Check the applicable consumer law and your own contract terms.
Should I offer compensation for a late delivery?
Consider what the delay actually cost the customer and what your contract requires. Refunding delivery charges, waiving expedited freight, or offering a credit are common. If the contract contains a liquidated damages or late delivery clause, that clause governs and a goodwill gesture does not displace it. Where a business customer claims consequential losses, take advice rather than conceding in the notice.
Can I change a delivery date after the order is confirmed?
Not unilaterally. A confirmed date is part of what was agreed, and telling the customer a new one is a notification, not a variation. Ask them to confirm acceptance of the revised date in writing. Whether a force majeure clause or a right to reasonable delay applies depends on the terms you contracted on, so read them before assuming you can move the date without consequence.
How much detail should I give about the cause of the delay?
Enough for the customer to judge whether the new date is realistic — the nature of the problem and where it sits in the chain — and no more. Two sentences is usually right. Avoid internal blame, avoid naming a supplier in a way that breaches confidentiality, and avoid dressing up a foreseeable problem as an unavoidable one, because that is the part customers remember when it happens again.
