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.
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.
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.
Before anything hits LHDN, you see exactly what they'll see — but with cryptic codes already translated. No 400-line fault dumps. No guessing which field broke.
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.
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.
Check it on MyTax — formats starting with IG are personal, C is corporate. Your buyer probably gave you the wrong one.
Line 3: 'Teh Ais' — map it once to LHDN's catalogue and we'll reuse it for every future sale.
Rounding issue — your spreadsheet rounded twice. We'll recompute and resubmit; no action needed on your end.
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.
The 7th of the following month is the safe default. Kiira submits on that day, every month.
POS export, Shopee payout, GrabFood settlement — whatever source you connected.
If a walk-in asked for a named invoice mid-month, we exclude them from the rollup. No double-counting.
SST aggregated correctly across the month — not three separate rounding operations.
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.

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.
Even consolidated B2C needs a tap — we remind you on the 7th, you approve, it ships.
Every draft sits as needs_review = true for 60 minutes. Reply 'nope' on WhatsApp, it's gone.
Every submission logged with prompt version, token counts, response payload. Regulated trail built in.
WhatsApp capture, invoices, dashboard, bank imports — all free. MyInvois submission sits on the Compliance tier (RM79/mo), which is the one LHDN is going to ask you about when Phase 5 lands.
Five phases, four invoice types, every rejection reason. Plain English.
1 Jul 2026 lands on every micro under RM150K. An 8-week runway.
One rolled-up invoice per month for walk-in sales. How it works.
Kiira's MyInvois module costs RM79/mo on the Compliance tier — no card until you actually need it. The rest of your books (invoices, expenses, bank imports) stays free forever.
