Asking for a review without becoming the business that pesters

Ask after they have used it, once, and ask whether it was alright rather than for a review. The second question gets answered far more often, and it catches the unhappy customer before they write the review anyway.

Timing is most of it

Delivery is not the moment. The moment is when they have used the thing and formed an opinion - which for a physical product is usually days, for a repair is the next time they need it to work, and for a service is the same afternoon.

Asking at delivery gets you an opinion about the delivery, which is not what you wanted to know.

Ask the better question

Weak:
Please leave us a 5 star review! [link]

Better:
Hi Wanjiku - the tyres went on Thursday. Everything
alright with them?

The second gets a reply. If the reply is good, then ask - "Would you mind saying that on our page? [link]". If the reply is bad, you have found a problem privately, which is worth more than the review would have been.

Make it one tap

• A direct link to the review form, not to a homepage.
• Say how long it takes. "Takes about a minute."
• Do not require an account if you have any choice about where you send them.

Once, and then stop

No sequence, no reminder, no second link. A review chase is the clearest possible signal that the message was about you rather than about them, and on WhatsApp it is what turns a satisfied customer into somebody who mutes you.

And the consent question

A review request is marketing in most readings. If your opt-in covered order updates only, it does not cover this - see what counts as consent. The cleanest version is asking inside a conversation the customer is already in, which is another argument for the timing above.
