I have a convenience store and want to do part-time express service. Where should I start and what is the operation process?

I suggest you do the same city express first.

Print some self-adhesive stickers first, just like business cards. (just stick it on the outside of the item! This is also a live advertisement. You can find another sponsor to collect advertising fees, but this is another matter, so I won't say it here.)

If you are ambitious, special packaging bags are better.

Print the store card, put it into government units or private enterprises, and charge a unified fee for the certificate (for example, 1.5 yuan city). If you need to get the +0.5 yuan, it will be delivered within one hour.

. . .

Please check the above amount and time data by yourself, as long as the initial market breaks even.

Wish you success!
