Are you using tracked services? When you are hit with a Dispute are you giving the tracking number in the Dispute? If your customers are contacting you without a Dispute, are you telling them the tracking number , the estimated delivery date, and the last place it was recorded?
The Dispute customers are probably a little more sophisticated than the contactors (?) so the latter may need more stroking and information.
You could also change your shipping service to a slower one, but keep shipping by the faster one. This may mean massaging your selling and shipping prices.
And finally, is this five out of ten sales? Or five out of 100? Or one out of 500? We feel those Disputes like a slap in the face, but run the numbers to see what is really happening.
FWIW- I not only ship from Canada but rarely track (because international tracking is very expensive*) and in 2021, I have had one NAD (my error!) and one Not Received out of some 65 sales. I find that high but we'll see what it is at the end of March.
* The lowest price for a Tracked Packet USA is $13,38 which only covers up to 100grams in weight. I know that I will lose any Not Received dispute, but tracking would cost me more than the occasional refund does.
