Real-Time Control. Zero Hassle.
Smart Utility Management.

Smart prepaid meters that eliminate utility debt, automate disconnection, enable instant top-ups, and provide complete control for property managers.

How It Works

Step 1

Tenant Top-Up

Tenants conveniently purchase utility credits through the mobile app or online portal. Payments are instant and secure.

Step 2

Instant Credit

Credits are immediately applied to the tenant's meter wallet via our 4G smart metering system. No waiting, no delays - instant activation.

Step 3

Real-Time Monitoring

Tenants track their usage in real-time through the app. Property managers monitor all meters, receive alerts, and access comprehensive analytics.

Step 4

Automatic Management

When balance depletes, meters automatically disconnect. Upon top-up, service instantly restores. Zero debt collection, zero hassle for property managers.

New Thai Consumer Law Bans Utility Markups

New Consumer Law Bans Utility Markups, Threatening Traditional Property Revenue

The Contract Committee's B.E. 2568 ruling strictly prohibits charging tenants above official PEA/PWA tariffs, effectively killing the traditional revenue model for landlords operating three or more units. This shift makes the old, non-compliant method a serious offense, carrying fines up to THB 200,000 and possible imprisonment. SiamSync provides the only certified, compliant path, ensuring all utility billing is at the mandated official rate and protecting your business from legal risk.

Condominium (Sukhumvit)

Mr. Saroj W.

Head Property Manager

Before SiamSync, 25% of our monthly revenue was tied up in debt collection legal fees. Now, collection is 100% automated and guaranteed. It’s simply not a problem anymore.

Large Apartment Complex (Pattaya)

Ms. Lena K.

Owner/Operator

We were losing good tenants over utility markups. Switching to official PEA rates with SiamSync made our units more competitive. Occupancy jumped 8% in three months.

Residential Community (Chiang Mai)

Mr. David P.

Investor

The real-time control is the game-changer. I can track every unit’s consumption and revenue from my phone in London. Full transparency, zero hassle for my local team.

Mixed-Use Building (Bangkok CBD)

Ms. Pimchanok C.

Building Administrator

The automated enforcement for common fees is priceless. No more chasing. If they don’t top up, the power goes off until *all* arrears are paid. It just works.

Property Developer (Phuket)

Mr. Ekkasit T.

Sales Director

Integrating SiamSync into our new development immediately reduces financial risk at handover. Our investors love the guaranteed cash flow model. It adds value.
