There could be several reasons why your e-way bill is not getting accepted by the customer or transporter. Some possible reasons could be incorrect or mismatched details in the e-way bill, such as incorrect GST number, vehicle number, or transporter ID. It is important to double-check all the information entered in the e-way bill and ensure its accuracy. Additionally, make sure that the e-way bill is being generated according to the rules and regulations set by the government. If the issue persists, it is recommended to contact the customer support of the BUSY for further assistance.
