Built by accountants who know the work.
We spent twenty years watching property managers, builders, and contractors fight the same battles: re-typing data between field apps, wrestling with QuickBooks, and piecing together spreadsheets to find their true numbers.
We built Zeno ERP because the operational and financial software real estate operators needed didn’t exist.
Accountants who write their own software.
Zeno ERP is built by Zeno Services, LLC in Brooklyn, NY. We keep real books, close months on real operating files, and write the platform that powers them. Neither the accounting controls nor the software architecture is an afterthought.
Founded by Eli Mandel
Master’s in Accounting from Fairleigh Dickinson University. Advanced Certified QuickBooks ProAdvisor in both Online and Desktop since 2009.
20 years keeping real books
Two decades of outsourced bookkeeping, controller oversight, and custom financial software for multi-million-dollar portfolios and operating companies.
Advanced ProAdvisors since 2009
Advanced Certified in both QuickBooks Online and QuickBooks Desktop. We know the accounting mechanics, the edge cases, and where generic tools break down.
Graduate accounting rigor
Built on formal accounting training: double-entry discipline, strict period close, balance sheet controls, and auditable transaction provenance.
Software written in-house
We write our own software from the database schema up. The ledger, operational workflows, and AI operator are engineered together as one cohesive engine.
Real estate doesn’t fit in a generic ledger.
Generic accounting systems don’t understand tenant leases, draw schedules, or subcontractor compliance. Industry apps don’t own a real double-entry general ledger. Operators end up stuck in the messy gap between them.
Five apps, endless sync errors, zero real-time truth
- Rent collected in property apps or checks in the mail must be manually re-keyed into QuickBooks.
- Contractor change orders and draw milestones live in spreadsheets while accounting books stay weeks behind.
- Owner distributions, sales tax, and job margins require manual exports and hours of formula cleanup.
- Multiple entities mean juggling dozens of separate company files and logins.
One unified platform. Zero re-entry. Complete financial control.
- Operations post to the ledger: Invoices, bills, checks, and payments update the general ledger the moment they are approved.
- Intelligent document pipeline: Forward checks, invoices, and bank statements; AI reads and stages them with zero guesswork.
- Multi-entity native: Run multiple LLCs, properties, and projects with cost-center dimensions and clean consolidated reporting.
- Enterprise audit trails: Full period close locks, attributable user writes, and complete transaction lineage.

Real Estate Developers
Track buyers, milestone payment schedules, contracts, and amendments across multiple entities and projects. Run draw schedules and AIA-style progress billing with cost verification pulled straight from the books.
Contractors & Builders

Autonomous AI with human review at the gate.
We don’t believe in black-box bots making blind adjustments to your general ledger. With Zeno Operator, AI handles the heavy extraction, matching, and preparation—but a human always inspects and approves the batch before a single dollar posts.
