Every LHDN acronym,
one toggle away.

We keep the Peppol schema, the validation rules, and the quirks of the MyInvois portal updated so you don't have to. Write an invoice the normal way. We handle the XML, the UUID exchange, and the embassy of error messages LHDN sends back.

Fields mapped 34 / 34

Three problems, three fixes.

LHDN's e-invoice regime has a lot of moving parts. The ones that trip up micros the most (validation, consolidated B2C, and the submission mechanics themselves) are what we built for first.

Submission

Peppol mapped, UUID handled.

You write the invoice normally. We render Peppol BIS 3.0 XML behind the scenes, POST it to MyInvois, catch the UUID, and stamp the QR on the customer's PDF. You never see the schema unless you ask.

  • All 34 required fields auto-populated from your customer + product records
  • Retries queue automatically if LHDN goes down, and ship the moment it's back up
  • Every submission logged for forensic audit trail
Validation preview

Errors in English, not XML.

Before anything hits LHDN, you see exactly what they'll see, with the cryptic codes already translated. No 400-line fault dumps. No guessing which field broke.

  • Sandbox dry-run on every draft before you press submit
  • Top rejection reasons flagged inline (TIN, classification, SST rounding)
  • Fix the customer record in one click, no separate trip back
Consolidated B2C

One rollup a month, done for you.

If you sell to walk-ins (kedai makan, retail, counter sales), you don't need per-customer invoices. Kiira tallies the month's counter takings and submits one consolidated B2C e-invoice on the day you pick.

  • Pulls from your daily sales summaries automatically
  • Submits within the 7-day window, no manual month-end scramble
  • Skips individually-invoiced customers (no double-counting)

What LHDN sees. In plain English.

Every submission runs through a sandbox dry-run first. The errors that come back (the ones your accounting software usually forwards untouched) get translated before you ever see them.

Buyer TIN

The buyer's TIN doesn't exist in LHDN's register.

Check it on MyTax: formats starting with IG are personal, C is corporate. Your buyer probably gave you the wrong one.

30 days of counter sales.
One e-invoice.

If your shop takes walk-in cash, you don't issue a separate MyInvois e-invoice per kopi. LHDN lets you roll up the month into one submission, as long as it lands within 7 days of month-end. Kiira does the rolling.

  • Pick your cadence day

    The 7th of the following month is the safe default. Kiira submits on that day, every month.

  • Pulls from daily sales summaries

    POS export, Shopee payout, GrabFood settlement: whatever source you connected.

  • Skips invoiced customers

    If a walk-in asked for a named invoice mid-month, we exclude them from the rollup. No double-counting.

  • Rounded to LHDN's rules

    SST aggregated correctly across the month, not three separate rounding operations.

Thirty-four fields. Mapped once.

LHDN wants 34 fields on every invoice. Most come from your customer record, your product catalogue, or your company profile; you fill them once. The rest (UUID, digital signature, submission timestamp) are ours to worry about.

Not even if you set it to.

Other tools run batch submissions overnight. That's fine until the night a bad invoice slips through and you find out when a refund comes in. We won't do that. Every submission is a human tap, and draft invoices live for an hour before anything moves.

  • No scheduled submissions

    Even consolidated B2C needs a tap. We remind you on the 7th, you approve, it ships.

  • One-hour undo window

    Every draft sits as needs_review = true for 60 minutes. Reply 'nope' on WhatsApp, it's gone.

  • Full forensic log

    Every submission logged with prompt version, token counts, response payload. Regulated trail built in.

Free tier does almost all of this.

WhatsApp capture, invoices, dashboard, bank imports: all free. MyInvois submission sits on the Compliance tier (RM79/mo), the one LHDN asks about once you cross RM1m, or when a customer needs an e-invoice from you.

Questions we keep getting asked.

Can I use Kiira for MyInvois if I book everything else in SQL Account / Bukku?

+
Plenty of our users run Kiira alongside an existing accounting package. We handle only the e-invoice submission layer and export clean entries back for reconciliation, so you don't have to migrate your books.

What happens if MyInvois is down when I hit submit?

+
LHDN allows a 72-hour grace period during outages. Kiira queues the submission automatically. The moment the service returns, the invoice goes through, and you'll get a WhatsApp confirmation with the UUID.

How does Kiira handle the 72-hour cancellation window?

+
Once LHDN returns a UUID, you have 72 hours to cancel the invoice cleanly. Past that, it's credit-note territory. Kiira shows you the countdown on every submitted invoice and lets you cancel with one tap before the window closes.

Do you handle self-billed invoices for foreign suppliers?

+
When you pay a foreign supplier who can't issue their own e-invoice (a Bali designer, a Shenzhen factory), Kiira generates a self-billed e-invoice on their behalf and submits it under your TIN, included in the Compliance tier.

What about credit notes and debit notes?

+
Credit and debit notes reference the original invoice's UUID and inherit its audit trail. From the customer's POS, it looks like a refund with a corrected e-invoice.

My accountant uses SQL Account. Can they still reconcile?

+
We export to SQL Account and AutoCount formats, and every submitted e-invoice carries its UUID + validation timestamp in the export. Their month-end reconciliation doesn't change.

When does Kiira update the Peppol schema?

+
Automatically. LHDN has shipped two minor schema revisions since Phase 1, and we rolled both out within 48 hours of publication, without anyone on your side lifting a finger. That's part of what you're paying for on the Compliance tier.
