What is the timeline given to supplier to submit e-invoice to MyInvoice portal? E.g. not more than 1 month? 2 months?

According to Section 2.3 of the IRBM’s e-Invoice Guideline, once a sales transaction has been concluded, the supplier must immediately submit the invoices for IRBM validation via either the MyInvois Portal or API. In the event of a connection failure with IRBM’s Portal, the supplier may resubmit the same transaction within 72 hours.  However, for consolidated e-Invoice, the supplier may submit within 7 calendar days from the end of the month.
