LHDN e-invoicing applies to veterinary clinics in Malaysia just like any other business. If your vet practice exceeds the revenue threshold for your compliance phase, you must submit e-invoices to MyInvois. Most established vet clinics — especially those offering grooming, boarding, and emergency services alongside consultations — crossed the RM500,000 threshold and were captured by the July 2025 phase. By July 2026, every vet clinic must comply. This guide covers the e-invoicing challenges specific to veterinary practices and how an integrated vet clinic management system handles them.
Why Is e-Invoicing Different for Veterinary Clinics?
Veterinary billing has unique patterns that general clinic software often does not handle well. A pet owner might bring two dogs and a cat in one visit, each needing different treatments. The invoice covers consultation fees, medications, vaccines, grooming, and possibly boarding — all for different animals under one owner. LHDN e-invoicing requires each invoice to be correctly itemised and submitted. Here is what makes vet billing uniquely challenging:
Multiple Pets Per Owner in One Visit
A single pet owner might bring two or three animals to a single appointment. Each animal needs separate examination notes and treatment records, but the invoice goes to one owner. The e-invoice must itemise treatments per animal while billing the owner as a single buyer. Your vet software must link pet records to owner profiles and generate consolidated invoices that correctly attribute items to each animal.
Medication and Vaccine Dispensing
Vet clinics dispense medications, vaccines, flea treatments, and consumables directly to pet owners. Each dispensed item must appear as a line item on the e-invoice with correct pricing and tax treatment. Clinics with inventory tracking need the dispensing record to update stock levels and generate the corresponding e-invoice line item simultaneously.
Grooming and Boarding Services
Many vet clinics offer grooming and boarding alongside medical services. A pet might see the vet for a vaccination, get groomed, and then stay for three nights of boarding — all on one invoice with different service categories. Each service type (medical, grooming, boarding) may have different tax treatments or pricing structures. The e-invoice must reflect all of these correctly.
Emergency and After-Hours Billing
Emergency vet visits often happen after hours and involve walk-in owners who may not be registered in the system. These B2C transactions without full buyer details must be handled via consolidated e-invoicing. Your vet software must support both individual e-invoices (for known clients) and consolidated B2C submission (for emergency walk-ins).
“Vet billing mixes medical, retail, and hospitality services on a single invoice. If your software does not handle multi-category itemisation, e-invoice compliance becomes a manual burden your team cannot sustain.”

How an Integrated Vet CMS Handles e-Invoicing
MedicalMet handles vet e-invoicing by connecting the pet-owner relationship, treatment records, product dispensing, and service billing into one integrated workflow. When a pet owner checks out:
- The vet records treatment notes for each pet in the visit.
- Dispensed medications and vaccines are added to the invoice automatically from the treatment record.
- Grooming and boarding charges are added as service line items.
- The front desk collects payment. The invoice is itemised per pet and per service category.
- MedicalMet submits the e-invoice to LHDN MyInvois automatically via API.
- LHDN validates the invoice and returns a QR code, which prints on the receipt.
The entire process happens without your staff needing to interact with the MyInvois portal. e-Invoicing is included in all MedicalMet plans at no extra cost. There are no add-on fees, no per-invoice charges, and no premium tier required.
e-Invoicing Included — No Extra Fees
Some clinic software providers charge extra for e-invoicing as a paid add-on. MedicalMet includes LHDN e-invoicing in all plans at no additional cost — because compliance should not be gated behind a paywall.
LHDN Compliance Timeline for Vet Clinics
The same phased rollout applies to vet clinics as any other Malaysian business. For a detailed breakdown of all phases, read our complete LHDN e-invoice guide. The key dates for most vet practices:
- 1 July 2025 — Vet clinics with annual turnover above RM500,000 must comply. This captures most multi-vet practices and clinics with grooming/boarding revenue.
- 1 January 2026 — Vet clinics above RM150,000 annual turnover.
- 1 July 2026 — All remaining vet clinics regardless of revenue. No exceptions.
If your vet clinic has not yet set up e-invoicing, the time to act is now. Non-compliance penalties under the Income Tax Act 1967 include fines of up to RM50,000 and imprisonment of up to 3 years.
Vet Clinic e-Invoice FAQ
Is e-invoicing mandatory for veterinary clinics in Malaysia?
Yes. Vet clinics follow the same LHDN e-invoicing requirements as all Malaysian businesses. By 1 July 2026, every vet clinic must submit e-invoices regardless of revenue. Clinics above RM500,000 annual turnover were already required to comply from July 2025.
How do multi-pet invoices work with e-invoicing?
A single e-invoice is submitted to LHDN for the pet owner (the buyer), with treatments for each pet listed as separate line items. The invoice is attributed to the owner, not to the individual animals. MedicalMet itemises treatments per pet automatically.
Do boarding and grooming services need e-invoices?
Yes. All commercial services provided by your vet clinic — including boarding, grooming, pet spa treatments, and retail product sales — must be e-invoiced. They are treated as business transactions under LHDN guidelines.
