2. My apologies for the late response. (Apologies is used as a verb)
3. You can accept my apology for the late response. (Apology is used as a noun)

Sorry or Apologize?

Sorry- an informal way to express your feelings. However, if you have become closer with the client (had several conversations, talked many times on the phone), you can always say ”Sorry”.

Apologize – a formal way to express your feelings.

Response or Reply?

The meaning is the same. Both are synonyms.
The only difference is that ”Response” is more formal than ”Reply”.

Why sometimes you should AVOID apologies?

You should not exaggerate the use of the word ‘Apology’ because the person on the other side will feel superior to you and can sometimes feel more powerful. Everything has its measure!
For example, you send a message that you apologize for the late response and after a couple of hours, you send the same message. You should avoid it!

How to answer when the customer apologizes to you?

You should not answer anything. You can continue to talk about your topic and disregard the late response.

Depends on the reason why you have delayed with the answer:

If you have been collecting information and the customer is aware of that:
– It’s okay to answer 1-2 days later but if you answer after one week you can add the magic word – Apology;

Nothing special, just some simple questions:
If you answer after 4-5 hours after their question:
– It’s okay to avoid the word – Apology;

If you answer after 1-2 days after their query:
– You should say – Apology;

Reasons why you have delayed your response:

Apologize, I was gathering information internally;
Apologize, I was pending our responsive team;
Apologize, I was out of the office;
Apologize, I had to accidentally leave the office earlier;
Apologize, I was at a meeting/event;
