What plugs in
Your PMS, your accounting, your payment processor, already supported.
The shortest path to utility recovery is the one that doesn't require your team to switch software. NES connects to the systems you've already standardized on. Charges flow into resident ledgers in your PMS. Recovered AR posts to your GL. Resident-facing statements live inside the portals your residents already log into. Your team gets a single owner dashboard for cross-portfolio visibility, without anyone having to learn a new tool.
PMS integrations
Eight platforms. One implementation each.
NES has standing integrations with the eight property management systems institutional owners actually use. Each integration is a real, in-production connection with documented charge mapping, not a generic webhook glued together at install time.

Accounting, payments, utility data, meters.

API and reporting
Direct API access. ENERGY STAR + GRESB exports. Custom roll-ups on request.
If your asset-management team wants raw utility data into their own BI stack, NES exposes a documented REST API for property-level reads, charges, and AR. Native exports for ENERGY STAR Portfolio Manager and GRESB benchmarks are included. Custom roll-up reports (by fund, region, asset class, or any custom dimension) are scoped during onboarding and refreshed on whatever cadence your investor reporting requires.
How an integration deploys
Integration is configuration, not engineering.
Four steps from contract to a live PMS connection. NES owns the mapping; your team approves it. No code on your side, no PMS vendor invoice.
01Day 0 - 3
Identify charge codes
NES reviews your existing PMS charge codes for utilities, late fees, and adjustments, then proposes the mapping for utility line items.
02Week 1
Connect and authenticate
NES connects to the PMS via the platform's standard integration channel (API key, SFTP, or vendor-provided connector). Owner approves the auth scope.
03Week 2 - 3
Run a test cycle
NES processes one billing cycle in dry-run mode. Owner reviews charges in the PMS staging environment before any post hits the production ledger.
04Week 4 onward
Go live
First production cycle posts. Reconciliation reports run automatically. NES monitors the integration for any drift and resolves vendor-side issues without involving your team.

Common questions
What property managers ask about integrations.
NES has certified, in-production integrations with Yardi, RealPage, Entrata, AppFolio, MRI / PayLease, ResMan, Rent Manager, and AMSI. If your portfolio runs on something else, like a home-grown platform, a legacy install, or a one-off accounting workflow, ask about custom integration scope during the portfolio review.
No. The point of the integration layer is that you don't change anything. Utility charges post into the PMS your team already uses, resident payments reconcile in your existing AR workflow, and the resident-facing experience stays inside the portals residents already know.
Three to four weeks from contract to a live production cycle. Week 1 is auth and charge-code mapping. Weeks 2-3 are a dry-run cycle in staging. Week 4 is the first real billing cycle posted to your production PMS.
Yes. NES exposes a documented REST API for property-level meter reads, charges, and AR. Authentication is API-key based. Rate limits are generous and there's no per-call billing.
Yes. Both formats are native exports. ENERGY STAR Portfolio Manager exports run on whatever cadence your benchmarking team requires (typically monthly or quarterly). GRESB exports run annually before the reporting deadline.
NES monitors every integration for breaking changes and updates the connector on our side without involving your team. We've maintained these integrations through every major PMS version migration since 2018.
Yes. Custom roll-up reports by fund, region, asset class, or any custom dimension are scoped during onboarding and refreshed on whatever cadence your investor reporting requires.
