SSI enQuesta
A utility-billing-focused customer information system used by mid-size municipal and cooperative utilities across North America.
A CIS purpose-built for mid-size utilities.
Systems & Software's enQuesta is a customer information system (CIS) — utility billing, customer service, meter data — used by mid-size municipal and cooperative utilities across the US and Canada. It's not a general ERP; it's a purpose-built utility CIS that integrates alongside a general-ledger ERP.
The customer base skews toward stand-alone utility districts and public power utilities in the 20k–500k account range. It competes most often against Harris NorthStar, Oracle Utilities CC&B (at the higher end), and Tyler UB (for cities where the utility isn't the primary driver).
Strengths & trade-offs
What buyers routinely love — and what they realise 12 months in.
Strengths
-
Utility-billing purpose-builtNot a bolt-on. The whole product is oriented around CIS — billing, service orders, meter reads.
-
Multi-utility (water, electric, gas)Serves combined-utility districts natively, not as a special case.
-
Rate flexibilityComplex rate structures, tariffs, and regulatory reporting handled with less customisation than general ERPs.
-
Strong mid-utility fitPurpose-built for 20k–500k account utilities — a segment where general-purpose ERPs feel light.
Trade-offs
-
Not an ERPFinancials and HR live elsewhere. Integration architecture must be designed upfront.
-
Reference base is nicheWell known in the utility-CIS community; less visible in general municipal ERP conversations.
-
Modernization ongoingCloud multi-tenant SaaS is available and adoption is growing, but not all customers are there yet.
-
Depth requires specialistsConfiguration is powerful; the talent pool is smaller than general ERP consultants.
What it costs
Enterprise subscription sized by utility accounts and modules. No published rates.
Cloud subscription for a mid-size utility (20k–100k accounts).
Traditional on-prem for utilities not moving to cloud yet.
MDM, self-service portal, mobile field service — often layered on.
Sized to account count and complexity. Combined-utility deployments trend higher.

Where enQuesta is the right pick
Mid-size municipal water utility
20k–100k account water/sewer utilities where a general-ERP UB module isn't deep enough.
Public power (municipal electric)
Public-power utilities where enQuesta pairs with a general-ledger ERP and OMS.
Combined-utility districts
Districts running multiple utilities together with unified customer accounts.
Rural electric cooperative
Coops where SSI competes directly with NISC, Milsoft, and Harris NorthStar.
What it plays well with
Common systems teams connect on day one.
- AMI / meter-reading (Sensus, Itron, Landis+Gyr)
- Payment processors (Paymentus, InvoiceCloud, Speedpay)
- General ERPs (Tyler, Munis, Workday, SAP, Oracle) via posting
- Esri ArcGIS
- SCADA / OMS systems
- DocuSign
- IVR / call center integrations

What we tell clients about enQuesta
enQuesta is the right answer when the utility is the strategic system and the general ERP is downstream.
For mid-size utilities where the CIS is the strategic system — billing complexity, regulatory reporting, service-order density — enQuesta is a serious purpose-built option that a bundled municipal ERP won't match on depth.
The architecture question is the important one. enQuesta plus a peer general-ERP is a well-understood pattern, but the integration must be designed upfront — not bolted on after the fact. KCT has seen the reverse fail badly.
