How to Choose a Smart Metering Vendor for Your Housing Society

Choosing the wrong smart metering vendor is expensive to fix. Meters are embedded in electrical panels, residents are onboarded to a platform, and switching mid-contract means a second round of installation disruption. Here are the questions to ask before you sign anything.

1. Are the meters BIS certified?

This is non-negotiable. Every energy meter installed in India for revenue purposes must be BIS certified. Ask the vendor to share the BIS certificate document — not just a sticker on the meter. Verify the certificate number on the BIS website.

Red flag: Vendor says 'our meters comply with international standards' or 'certification is in process.' Do not accept uncertified meters.

2. Who handles installation, software, and AMC?

Some vendors supply meters but outsource installation to local electricians. Others provide the billing software but the hardware comes from a third party. When something goes wrong — and eventually something will — you need one vendor who is accountable for the whole system.

Ask: 'If a meter shows wrong readings and my billing platform shows wrong data, who is responsible?'

What to look for: One company that manufactures or sources the meters, installs them, provides the software platform, and signs the AMC. Fewer handoffs means fewer excuses.

3. How does the system handle DG separately from mains?

This is the most technically important question for societies with generator backup. DG electricity costs significantly more to produce than grid power, and that cost must be passed on to the residents who used it — not averaged across everyone.

Ask the vendor to demonstrate how DG and mains consumption appear separately in the billing report. Ask what happens during a DG-to-mains switchover — is there any gap in recording?

Red flag: Vendor says 'DG tracking is available as an add-on' or can't show you a live demo of dual-source billing.

4. Can we see a reference installation?

Any vendor with genuine deployments will offer to connect you with an existing customer. Visit the site if possible, or at minimum call the contact and ask: How long has the system been running? Have there been meter failures, and how quickly were they replaced? Do residents find the app easy to use?

Red flag: Vendor cites installations but can't give you a contact name and number for any of them.

5. What does the AMC actually cover?

AMC terms are where vendors hide the traps. Read the contract carefully for:

Response time for meter failures (24 hours? 72 hours? 'Best effort'?)
Whether replacement meters are included or billed separately
Software platform uptime guarantee
Whether the AMC covers all meters or only the vendor's own make

A vendor who has been maintaining sites for more than 10 years can point to long-running contracts as evidence. A vendor who is new to AMC may write generous-sounding terms they cannot deliver.

6. What happens to our data if we end the contract?

Your billing records are your records. If you end the contract, can you export all historical consumption records per flat, all recharge and payment history, and resident account data? Some platforms lock data behind proprietary formats. Insist on data portability in the contract before you sign.

Red flag: Vendor says data export is possible 'on request' with no timeline or format specified.

7. Is there a pilot option?

For large societies (200+ flats), ask about piloting with one wing or one floor before full rollout. This lets you evaluate the meter accuracy, software UX, and vendor responsiveness at low risk. A confident vendor will offer this without hesitation.

The proposal checklist

When you receive a vendor proposal, check it against this list:

BIS certificate number provided and verifiable
Meter specifications (single/three-phase, dual-source capability)
Itemised scope covering meters, installation, and platform
AMC terms with specific SLAs
Reference contacts provided
Data portability clause in contract
Payment terms and what triggers final payment

A good proposal answers all of these without you having to ask. If you receive a one-page quote with a total number and no breakdown, ask for a detailed proposal before proceeding.
