Ukubeka

Gcina indawo yokugcina umoya evulekile futhi epholile.

Ukukhokha

* Singahlinzeka ngezindlela ezahlukahlukene zokukhokha zokukhetha amakhasimende.
* Lapho inani lincane, amakhasimende ajwayele ukukhokha nge-PayPal, Union asentshonalanga, i-Alibaba, njll.
* Lapho inani likhulu, amakhasimende ajwayele ukukhokha nge-T / T, l / c lapho ebonakalayo, i-Alibaba, njll.
* Ngaphandle kwalokho, amakhasimende amaningi futhi amaningi azosebenzisa i-Alipay noma i-WeChat akhokhe ukuze akhokhe.

Mayelana nokuhamba

* Singahlinzeka izinhlobo ezahlukene zokuhamba ngokubheka izimfuno zamakhasimende.
* Lapho inani lincane, singathumela ngendiza noma nge-FedEx, njengeFedEx, DHL, TNT, EMS kanye nemigqa ehlukahlukene yezokuthutha yezokuthutha.
* Lapho ubungako bukhulu, singathumela ngolwandle ukuze baqokwe ethekwini.
* Ngaphandle kwalokho, futhi singanikeza ngezinsizakalo ezikhethekile ngokuya ngezidingo zamakhasimende kanye nemikhiqizo.
