MAYAM
LHDN e-Invoice · Mayam POS

LHDN e-invoicing,
built into every sale.

Mayam sends every e-invoice to LHDN MyInvois from the same screens your counter already uses: sales, cancellations, credit notes, buybacks and the month-end consolidated invoice. Included in every plan, and set up for you by our team.

At the Counter

The customer pays. Mayam handles LHDN.

  1. 1

    The receipt prints

    The moment the customer pays, with a Mayam QR code on it. No waiting at the counter for LHDN.

  2. 2

    Sent in the background

    Mayam submits the e-invoice to LHDN MyInvois while your team serves the next customer.

  3. 3

    Validated by LHDN

    The e-invoice comes back validated with its LHDN UUID, recorded against the sale.

  4. 4

    The customer gets it

    By WhatsApp, or by scanning the QR on the receipt, which opens their e-invoice on LHDN’s site.

Every Document, Automatically

Five kinds of e-invoice.
None of them by hand.

A gold shop does more than sell. Returns, buybacks, trade-ins and walk-in customers each need the right document, and Mayam raises each one from what happened at the counter.

  • Submission

    Every sale a customer asks an e-invoice for goes to LHDN in the background and comes back validated with its UUID.

    Validated
  • Cancellation

    Void a sale within LHDN’s 72-hour window and its e-invoice is cancelled with LHDN too. No logging in to MyInvois.

    Cancelled
  • Credit notes

    Returns, refunds, price adjustments and sales cancelled after 72 hours raise a credit note linked to the original e-invoice.

    Credit note
  • Self-billed buybacks and trade-ins

    Gold bought back from the public, or traded in against a sale, gets its own self-billed e-invoice at today’s rate.

    Self-billed
  • Month-end consolidated

    Walk-in customers who don’t ask for an e-invoice are consolidated into one e-invoice at month end.

A business buys from you
Look up their TIN at the counter and their tax details fill in for the e-invoice.
A piece comes back next week

LHDN can’t accept an e-invoice
