Conservice vs EnergyCAP vs Measurabl
A very common combined evaluation when cost reporting and carbon reporting land on the same desk: a managed service, a cost accounting platform, and an ESG specialist.
A commercial real-estate operations lead who has just inherited carbon reporting alongside utility cost management will run exactly this evaluation. Conservice offers to take the whole process away. EnergyCAP offers rigorous cost accounting. Measurabl offers the ESG disclosure output.
The three are not interchangeable, and the temptation is to pick the one that covers the most ground on paper. That usually means the managed service, because a service can promise any output. The question to press is what you receive: a report, or a dataset you can interrogate when someone asks how a figure was derived.
The three-way nature of this shortlist is itself the signal. When one evaluation spans a service, a cost platform, and an ESG platform, the underlying requirement has not been separated into its parts, and the part that is common to all three is complete, traceable utility data.
Each is a serious company. Conservice is the largest utility expense manager in North America, serving millions of service locations and paying more than $12 billion in utility bills a year, and it extended into ESG reporting by acquiring Goby in 2021. EnergyCAP has four decades of utility cost accounting behind it, benchmarks more than 16,000 properties in ENERGY STAR Portfolio Manager, and added real-time device analytics by acquiring Wattics in 2022. Measurabl reports more than 1,000 customers and over 18 billion square feet of real estate across 90+ countries, and is the dominant route into GRESB. None of that is in question. What is in question is which of them owns the step your program actually breaks on.

Rows marked “via partner network” are delivered by Nectar partners (energy brokers, procurement consultants, and trading desks in the Nectar Marketplace of Solutions), rather than by Nectar directly. Bill pay is executed by Nectar or through an integrated payment provider depending on the customer.
Competitor details are taken from each vendor’s own published material and were accurate at the time of writing: Conservice, EnergyCAP, Measurabl.
What each vendor is actually good at
Conservice
A large utility expense management provider delivering bill collection, audit, and payment as a managed service, with particular depth in multifamily and commercial real estate.
Best fit for
Multi-site owners who want the whole utility process handled by someone else and are comfortable trading self-service for coverage.
Where Conservice wins
- Enormous operational scale and established real-estate relationships
- Executes bill payment and manages utility vendor relationships
- Resident and tenant billing workflows alongside expense management
- A single vendor for collection, audit, payment, and reporting
Where Nectar wins
- Nectar is self-serve software with a live completeness view rather than a reporting cycle
- Published coverage and accuracy figures you can hold us to
- Interval and meter-level data alongside billing data
- A raw data API for brokers and software companies
EnergyCAP
A long-established energy and utility bill accounting platform, strong in public sector, education, and government, with deep budgeting and cost-accounting features.
Best fit for
Energy managers who need rigorous utility cost accounting, budget variance, and chargeback against a defined organizational hierarchy.
Where EnergyCAP wins
- Mature utility cost accounting with deep budgeting and chargeback
- Long track record in public sector and higher education procurement
- Established GL and ERP integration patterns
- A large installed base and correspondingly deep domain features
Where Nectar wins

- A modern API for brokers and software companies consuming the feed
Measurabl
The most widely adopted ESG data platform for commercial real estate, covering benchmarking, GRESB submission, and portfolio sustainability reporting.
Best fit for
REITs and real-estate investors whose primary requirement is portfolio ESG disclosure and GRESB performance.
Where Measurabl wins
- Dominant adoption among real-estate investors and GRESB submitters
- Deep benchmarking and portfolio ESG reporting features
- Established data-sharing relationships across the CRE ecosystem
- Broad market recognition in institutional procurement
Where Nectar wins
- Nectar goes deeper on the bill itself, with line-item parsing and published accuracy
- Coverage of 7,000+ providers globally, including non-real-estate sites
- A data completeness view with one-click actions rather than a coverage report
- A raw data API for brokers and software companies
Where each vendor earns its position
Conservice wins where the buyer wants the entire process gone: collection, audit, payment, and resident billing handled by one vendor with real operational scale. EnergyCAP wins where an energy manager needs chargeback, budget variance, and general ledger reconciliation against a defined organizational hierarchy, which is why its installed base runs deep in government, K-12, and higher education. Measurabl wins where the audience is an institutional investor and the deliverable is a GRESB submission.
The pattern across all three is that collection is an input to the product, not the product. Conservice collects as part of a service cycle you cannot see into. EnergyCAP largely receives bills through imports, EDI feeds, and manual entry. Measurabl ingests data through integrations and uploads and reports on what arrives. Each one assumes the bills show up; none of them makes a live, per-meter answer to "what is missing right now" the thing you are buying.
Nectar inverts that. Automated collection from 7,000+ providers is the core product, every bill is parsed to line-item detail at a published 99.2% accuracy with human QA on anything flagged, and completeness is a surface you can check at any moment rather than a question you ask a vendor. Cost views, anomaly detection, bill pay, and exports to ESG platforms sit on top of that layer instead of substituting for it.
The layer none of these three operate
Every platform on this page depends on utility data arriving from somewhere, and none of them treats collecting it as the core product. That is not a criticism. It is a description of where each one chose to add value. It does mean the question buyers should ask is not which of the three is best, but which one solves the problem you actually have, and whether the data underneath any of them is good enough to trust.
Nectar operates that underneath layer. We connect directly to more than 7,000 utility providers globally, parse every line item (demand, supply, delivery, taxes, fees) at 99.2% accuracy with human QA on anything flagged, and show completeness as a live view at site, account, and meter level. Every value links back to the bill image it came from.
That is why Nectar most often runs alongside one of these platforms rather than instead of it. The reporting layer you choose is a real decision with real trade-offs; the data feeding it should not be the weak point in either case.
What assurance actually tests
When an assurance provider reviews a sustainability disclosure, they do not audit the platform. They sample reported figures and ask what evidence supports each one. A number that cannot be traced to an underlying record is a finding regardless of how sophisticated the system that produced it.
This is where the collection layer determines whether a reporting platform can be defended. If utility data arrived by spreadsheet, by manual entry, or by an integration that discarded the source document, the evidence chain has a hole in it that no amount of methodology closes.
Nectar retains the bill image, the parsed line items, the meter identifiers, and the service period together, so answering an assurance question is a lookup rather than an investigation, and estimated values are labeled as estimates rather than silently mixed with metered ones.
Why teams have switched
The switching patterns are consistent. Real estate operators who ran a managed service for years have moved the data layer to Nectar after a lender or auditor asked for the source bill behind a reported figure and the retrieval took weeks; they kept the service relationship where it still earned its fee and took back the dataset. Universities and municipalities that ran cost accounting on manual imports have added Nectar underneath after a staffing change broke the import routine and a semester of bills went missing without anything surfacing it.
Sustainability teams reporting into GRESB or CSRD have switched their collection layer for a different reason: assurance. A benchmarking submission built on estimates and uploads survives until someone samples it. Metered values with a bill image behind every number, and estimates labeled as estimates, is what that sampling actually tests for, and it is the difference between an evidence lookup and a scramble.
The common thread is that nobody switched because a feature list won a bake-off. They switched because a specific question, "where did this number come from" or "which meters are missing this quarter", had no good answer under the old arrangement, and it has a one-click answer in Nectar.
Where Nectar fits
Separate the requirement before choosing. Conservice if you want the process outsourced including payment, EnergyCAP for in-house cost accounting depth, Measurabl for institutional ESG disclosure. All three assume complete utility data and none of them makes collecting it their core product. Nectar does: automated collection from 7,000+ providers across 9 commodities, line-item parsing at a published 99.2% accuracy, a live completeness view, an audit trail to every source bill, and bill pay on the same platform, without a multi-year service agreement. That is why portfolios that started with one of these three have ended up putting Nectar underneath it, and a 30-day free pilot on your own bills is the cheapest way to test whether yours should.
Frequently asked questions
How do we decide between outsourcing and software here?
By whether anyone internally will own the outcome. Software concentrates the work into automation and leaves ownership with you; a service moves both. If nobody will look at a completeness view, software will underperform its promise regardless of features.
Can a managed service produce assurance-ready ESG data?
It can, but ask precisely how. Assurance samples figures and requests source records, so what matters is whether you can retrieve the bill behind any number quickly, and whether estimated values are labeled. Get that answered concretely rather than in principle.
Do we need all three?
Rarely. Most portfolios need one utility data layer, one place to do cost accounting, and one place to do disclosure, and the data layer is the piece most often missing, because each of the other two assumes it exists.
What does Nectar replace in this shortlist?
The collection and validation function, wherever it currently sits: the manual chase, the bulk uploads, the service cycle. It does not replace cost accounting depth or ESG disclosure formatting.
