Will the supplier’s invoice number remain in the invoice document or will a different invoice number be assigned by IRBM upon the return of the validated e-Invoice to the supplier?

The supplier’s invoice number will remain as a separate field in the same invoice document for the purpose of the supplier’s internal reference and tracking.

Upon validation, the IRBM will assign a Unique Identifier Number to each e-Invoice.   

供应商原有的发票号码是否仍会保留,还是在电子发票验证后由 IRBM 重新分配新的发票号码? 

供应商原有的发票号码(invoice number)仍会保留在电子发票文件中作为独立字段,以便供应商进行内部参考和记录追踪。
当电子发票通过验证后,马来西亚内陆税收局(IRBM)会为每一张电子发票分配一个唯一识别号码(Unique Identifier Number, UIN)。
因此:
  • 供应商发票号码继续保留用于内部管理
  • IRBM 唯一识别号码(UIN用于系统验证及官方记录识别
