u do online business but dunno? don't compare maxis n your business. one is service while yours is products based. They run in two diff modal n method. Let me explain why most courier charge min 1kg.

by air mail, usually u charter air plane to send goods around, doesn't matter if u have your own plane like dhl or ups or none. Two factor always limit which are the weight n volume. By volume mean how much space u take inside the airplane and by weight, mean how heavy it is

so your item can weight just 1kg but as big as large box. For courier company we see that as space wastage. same princple apply for small items. Bringing small items less than 1kg consume alot of space. Courier prefer u just buy one big box instead if small small box. Save sorting time and lower cost. Having 1kg as min weight is just ti cover cost.

The word customer first is a lie, for any company profit is first, customer only second. No point having alot of customer but marginal profit

well the good thing have own plane like dhl n fedex is that you can set your departure time n weight limits. I am sure u notice how fedex price is still way higher than pos laju increased rate? instead of paying min weight, what u are paying is actually cost to operate their own aircraft fleet. u gain flexibility but at a higher cost.

what pos malaysia do is charter flight, for example there a flight going to japan by japan air. Pos malaysia will rent an luggage compartment. Japan air dont care how many items u put in as long it does not overweight or too large. So let say u sending just 100kg but the max weight is 500kg. that mean u suffer an operationg lost of 400kg. Or one huge box tat take up most of the soace but weight 1kg only. Overall is stil cheaper than running own air plane to transport around

start selling bigger n heavier item or

as buyer buy more to reach 1kg by giving special price
