How to write an English email about an order mistake (A2 elementary): sorry, what you corrected and what happens next

A woman shows a colleague a document at her desk.

A2 English for order problems at work: names of business documents, the past simple with was, were and -ed verbs, apologizing and responding, and a short email that says what went wrong, what you fixed and what happens next.

A clear problem email in English says three things: what was wrong, what you already did and what happens next. Use the past simple for the first two: “The delivery note was wrong. I corrected the quantity.” Use “will” with a time for the next step: “The chairs will arrive before Friday.” Start with one short apology and put the order number in the subject line. This A2 (elementary) topic is for people who handle simple orders in English and now need to explain a mistake to a customer or colleague. Ten minutes of practice a day is enough.

Who this is for

  • People who can take or confirm a simple order in English and now need to explain what went wrong with one.
  • Anyone in sales, logistics, purchasing or customer service who sends invoices, delivery notes and short emails to customers.
  • Learners who still write “I correct it yesterday.” or mix up “was” and “were”.
  • Too early: if you can’t yet confirm an order, its total and its delivery day in a short email, start with order confirmation emails at A1.
  • Too easy: if you already record customer complaints with an owner and a follow-up date, move on to that A2–B1 topic.

Maya shows a colleague a document at her desk.

Yesterday North Dock received an order form for twelve chairs. Maya printed the form and sent it to the warehouse. Owen checked the stock, but he entered twenty chairs on the delivery note. The customer called this morning. Maya apologized, corrected the document and promised a new delivery before Friday.

Use the words in context

Maya and Owen at work: communication.

Owen Why did the customer call this morning?

Maya The delivery note said twenty chairs, but the order form said twelve.

Owen What did you do?

Maya I corrected the delivery note and attached it to an email.

Owen Did you send a new invoice too?

Maya No. The invoice was already correct.

Business documents: order form, invoice, receipt, delivery note

“Invoice” and “receipt” are easy to mix up: an invoice asks for payment, and a receipt shows that the payment was made. The “p” in “receipt” is silent.

  • “order form”, the customer’s request for products: “The customer sent an order form.”
  • “invoice”, a request for payment: “The invoice has the wrong total.”
  • “receipt”, proof that the customer paid: “Keep the receipt.”
  • “delivery note”, the list that travels with the goods: “Check the boxes against the delivery note.”

What went wrong: was, were and -ed verbs

Use “was” with I, he, she, it and one thing, and “were” with you, we, they and plural nouns: “The order was correct.”, “The boxes were late.” Regular verbs add -ed: checked, printed, called. Verbs ending in -e add only -d (apologized), and a consonant + y becomes -ied (copied).

Say -ed as an extra syllable only after a t or d sound: “printed” and “corrected” have it; “checked” and “called” do not.

  • “The delivery note was wrong.”
  • “The chairs were in the warehouse.”
  • “I entered twenty chairs.”

Questions and negatives: did and didn’t

In questions and negatives, “did” carries the past, so the main verb stays in its base form. With “be”, you don’t need “did”.

  • “Did you check the stock?” – “Yes, I did.”
  • “We didn’t send a new invoice.”
  • “Was the delivery note correct?” – “No, it wasn’t.”

Reporting a problem to a colleague

Before you write to the customer, agree the fix with a colleague: name the problem, say what you need to do and promise an update with a time. In this conversation, Owen reports a wrong delivery note and Maya agrees to fix it. “By three” means “not later than three o’clock”.

  • “We’ve got a problem with order 612.”
  • “We need to correct the delivery note.”
  • “I’ll call the customer.”

Owen We've got a problem with order 612. The delivery note is wrong.

Maya I'm sorry about that. We need to correct it.

Owen Can we send a new note today?

Maya Yes. I'll correct it and call the customer.

Owen That would be great. Thanks a lot.

Maya No problem. I'll let you know by three.

Apologizing and responding

One short apology is enough. Use “sorry about” or “sorry for” with a noun, stress SORry, MIStake and deLAY, and let your voice fall at the end. To respond, accept the apology and thank the person.

  • “I’m sorry about the mistake.”
  • “I’m very sorry for the delay.”
  • “That’s OK.”
  • “Don’t worry. Thanks for fixing it.”

A four-part problem email

Keep three things apart: what was wrong, what you already did and what happens next. A subject line like “Problem” tells the reader nothing, so name the order and the result.

  • 1. Subject line: “Order 612 – corrected delivery note”
  • 2. Apology and problem: “Hello Ana, I’m sorry about the mistake on the delivery note. It said 20 chairs, but your order was for 12.”
  • 3. What you did: “I corrected the quantity and attached the new note.”
  • 4. Next step and close: “The chairs will arrive before Friday. Best, Maya”

Common mistakes

These mistakes are easy to notice:

  • “I correct the note yesterday.” A finished action needs the past: “I corrected the note.”
  • “We didn’t sent it.”, “Did you checked it?” After “did” and “didn’t”, use the base verb.
  • “The boxes was late.” Plural nouns take “were”.
  • “I will correct the note.” when it’s already done. Say “I corrected the note.”
  • “Check-ed” with two syllables. “Checked” has one and ends in a /t/ sound.

A 10-minute daily practice routine

Practise out loud, in the same order each day.

  • 2 minutes: say each document word in a sentence.
  • 3 minutes: write five sentences about yesterday at work with was, were, -ed verbs and didn’t.
  • 3 minutes: play the conversation, repeat each line, then change the order number and the time.
  • 2 minutes: write a four-part email about a real or invented mistake.

What comes next

Next, practise a follow-up email after meeting a new business contact. At A2–B1, you record customer complaints with an owner and a follow-up date.

Frequently asked questions

How do you apologize for a mistake in a business email?

Start with one short apology that names the problem: “I’m sorry about the mistake on the delivery note.” Then say what you did and what happens next. “We apologize for …” is more formal and common in company messages.

What is the difference between an invoice and a receipt?

An invoice asks the customer to pay. A receipt shows that the customer has already paid.

How do you pronounce -ed in the past simple?

After t or d, it is an extra syllable: printed, needed. After voiceless sounds such as k, p, s and sh, it sounds like /t/: checked, stopped. After other sounds, it sounds like /d/: called, delivered.
