Best PM software for a small commercial portfolio (under 20 units)

Ryan Stomel · 2026-03-14T11:01:56-07:00

I manage a small commercial portfolio — mix of retail, one industrial, and a couple of office suites. Under 20 units total, all NNN or modified gross leases. I've been on a spreadsheet + QuickBooks combo and it works until CAM reconciliation season, at which point it turns into a nightmare.I've spent weeks looking at the usual options and the gap is pretty clear:Yardi / MRI — massive overkill for my size, priced for institutional operators, and implementation alone is a multi-month project. Not a fit.AppFolio — primarily residential. Their commercial module is an afterthought. CAM tracking is manual, lease structure flexibility is limited, and support confirms they focus on multifamily.Buildium / DoorLoop / Rent Manager — Same issue. These are built for units-based residential PM. They can technically hold a commercial lease but they're not designed for NNN reimbursements, escalation clauses, or year-end reconciliation.RealPage — Enterprise only, pricing not publicly available, minimum portfolio size requirements.What I actually need:- Clean rent roll with NNN/gross/modified gross lease structures- CAM estimate tracking per tenant (budget vs. actual)- Year-end reconciliation workflow- Rent escalation reminders- QuickBooks integration- Maintenance tracking- Not priced for a 500-unit institutional operatorHas anyone found something that actually fits this profile? We've been testing PigJet (pigjet.com) which was built specifically for this segment — small/mid CRE operators with commercial leases — and it's the closest fit we've seen. Curious if others have found alternatives or have experience with tools at this scale.For what it’s worth I compared the main options here if useful: https://pigjet.com/blog/best-commercial-property-management-software-small-landlords

@Ryan Stomel You’re not crazy, that gap definitely exists. Most PM software is built either for large commercial portfolios or residential landlords, and small commercial owners end up stuck in the middle.

For a portfolio your size, a lot of owners stay with QuickBooks and use something simple to track leases and CAM separately. Rent Manager is probably the closest of the common platforms because it allows more customization for reimbursements and escalations, even though it’s not perfect.

I’ve also seen people keep accounting in QuickBooks and track CAM in a structured spreadsheet. Not elegant, but it avoids paying enterprise pricing for software designed for 500+ units.

Honestly there still isn’t a perfect platform for the under-50-unit commercial owner. Most people end up building a simple system that works rather than relying on one piece of software to do everything.

Rod — you're right that it exists, and you're also right that the spreadsheet + QuickBooks combo is what most people end up cobbling together. Rent Manager is probably the most configurable of the accessible options, but I've found even it requires significant workarounds once you're dealing with CAM caps, exclusion audits, or multi-tenant gross-ups on the same property.

The patchwork problem is exactly what led me to start testing PigJet (pigjet.com) — it was built specifically for small CRE operators with commercial lease structures rather than adapted from a residential platform. Native NNN/modified gross support, CAM budget-vs-actual tracking per tenant, and year-end reconciliation workflow built in. Still early but it's the first tool I've found that doesn't require me to maintain a parallel spreadsheet for everything the software can't handle.

For anyone in the under-50-unit commercial segment dealing with the same thing, worth taking a look.

Ryan, you've actually done better homework than most people who post this question. The gap you identified is real and it's not going away anytime soon.

A couple things that might help.

You dismissed Yardi, but you may have dismissed the wrong product. Yardi Voyager is the enterprise platform with the multi-month implementation and institutional pricing. Yardi Breeze Premier is a separate

product built for smaller operators — runs around $400/month for a portfolio your size and has native commercial lease support including NNN structures and CAM tracking. It's not Voyager-lite. Most people don't know it exists because Yardi's sales team pushes Voyager to anyone who calls. Worth a direct look.

The other thing — and this took me a long time to learn — at under 20 commercial units, the problem is almost never software. It's workflow. I've seen operators on enterprise platforms with 500 units who still dread CAM reconciliation, and operators on QuickBooks with 30 units who close it in two days. The difference comes down to three things:

Lease abstracts that actually capture the reimbursement terms. Most operators abstract the base rent and skip the CAM pool definitions, exclusion clauses, caps, and gross-up provisions. Then January hits and they're reading leases for the first time in a year trying to remember which tenant has a 5% admin fee cap and which has a CPI escalation on controllables only. One standardized abstract per tenant — every reimbursement term on one page — turns reconciliation from archaeology into arithmetic.

A GL structure that maps to your CAM pools. If your QuickBooks chart of accounts doesn't separate controllable from non-controllable operating expenses at the property level, no software will fix the reconciliation. The GL has to mirror the lease structure. Most operators set up QuickBooks for tax reporting, not lease compliance. Those are two different jobs.

Quarterly prelim reconciliation instead of annual. This one changed everything for me. Run a rough reconciliation every quarter even if you don't send statements. It takes 30 minutes per property when you do it quarterly. It takes three weeks when you let twelve months pile up.

The spreadsheet + QuickBooks combo you're on right now might not be the problem. The implementation of it probably is. If you do want a dedicated platform, Rent Manager with the commercial module and Yardi Breeze Premier are the two worth evaluating at your scale. But I'd fix the workflow first — you might find you don't need to switch anything.

Ryan this thread is genuinely useful. The gap you described is real and I don't think it's going away anytime soon. Most of these platforms were built for residential and just bolted on commercial as an afterthought. Nicholas makes a good point about workflow but at some point the workflow workarounds exist because the software doesn't actually fit the lease structure. CAM reconciliation shouldn't require an archaeology project every January.

I ended up using Hemlane for a client because he ended up purchasing a mixed use building. I've not dealt with NNN leases in it specifically but it seems pretty flexible and able to handle it to some extent. its pretty nice for managing multiple properties with multiple units in each at least in my experience.

Michael — Hemlane is solid for residential-focused mixed use but the NNN piece is the gap worth probing on. For a portfolio with actual NNN or modified gross leases, the key question is whether it tracks CAM budget vs. actual per tenant and produces a year-end reconciliation statement — or whether that still lives in a spreadsheet alongside it.

After running into that wall with every residential-first platform I tested, I ended up building PigJet (pigjet.com) to handle exactly that workflow. Native NNN and modified gross lease structures, CAM estimate tracking with budget-vs-actual per tenant, year-end reconciliation built into the workflow, and QuickBooks sync at the property and tenant level. Built specifically for the under-50-unit commercial operator that's too small for Yardi Voyager and too CRE-specific for AppFolio or Hemlane.

For anyone on this thread in that segment — worth a look if you're still patching together the CAM recon piece separately.

Ryan, this is a real gap, and you're not imagining it. I'm on the residential side, but I've talked to enough small commercial operators to know that the sub-50-unit NNN space is genuinely underserved by software.

The core problem is that residential PM software thinks in terms of units and monthly rent, while commercial PM software assumes 500+ unit portfolios with dedicated accounting teams. If you're a 15-unit operator doing your own CAM reconciliation in Excel, neither world was built for you.

Nicholas's advice about workflow is the most important thing in this thread. Before you pick software, nail down:

Lease abstracts — Every lease summarized on a single page: base rent, escalation schedule, CAM pool, expense stops, and options. If you don't have these, no software will save you from reconciliation headaches.
Quarterly preliminary reconciliation — This is the move. If you're only reconciling annually, you're guaranteed a January nightmare. Quarterly check-ins—even rough ones—turn year-end into a confirmation exercise instead of a discovery process.
GL structure that maps to CAM pools — Most reconciliation pain comes from expenses that weren't categorized correctly throughout the year, not from the math itself.

On the software side, I don't have direct experience with PigJet, but the fact that it keeps coming up in these discussions says something. Yardi Breeze Premier at roughly $400/month is real money for a small portfolio, but if it saves you 20+ hours during reconciliation season, the math works.

One question: are your leases mostly standard NNN, or do you have a mix of modified gross leases? That changes the recommendation significantly because modified gross reconciliation is a very different animal.

Your analysis of the commercial software gap is completely accurate—traditional property management tools are fundamentally broken for small-balance commercial landlords. Mainstream platforms like AppFolio or DoorLoop treat commercial leases as an afterthought, forcing you back onto spreadsheets the moment you need to run a complex Common Area Maintenance (CAM) reconciliation, handle an escalation clause, or calculate a base-year stop. At the same time, Yardi and MRI are cost-prohibitive behemoth systems built for institutional REITs.

Testing PigJet is an excellent operational move. It is part of an emerging class of specialized niche platforms explicitly built for small-to-midsize commercial operators. It natively automates budget-vs-actual CAM tracking, schedules rent escalation triggers, and integrates directly with QuickBooks to eliminate double-entry accounting errors.

Keeping your portfolio metrics tightly organized inside a dedicated commercial engine does more than save your sanity at year-end—it positions you perfectly for scaling. Handing stakeholders or financial partners pristine, software-verified lease abstracts and clean trailing financial data allows them to evaluate your real performance instantly, proving your strong Debt Service Coverage Ratio (DSCR) and asset management competency with total clarity.

The gap is real, but at under 20 units your problem isn't software, it's process. Admittedly I made product for exactly this. I know -- a shameless plug, but at LeaseDesk.co it has everything you need and is perfect in-between unnecessary software and what is essential.

Ryan — this is a real gap, not just you being picky. AppFolio/Buildium/DoorLoop/Rent Manager are all built around unit-based residential rent rolls. CAM reconciliation — pro-rata expense allocation across NNN and modified gross leases, escalations, year-end true-ups — is a completely different data model, and it's usually bolted on as an afterthought if it's there at all.

For a portfolio your size, CAM reconciliation isn't actually a massive build — lease terms, pro-rata shares, expense pools, and a clean reconciliation statement output. Nowhere near Yardi-scale, and nowhere near a multi-month project.

Happy to talk through what that would actually look like for your specific lease mix — no pitch, just want to see if it's a real project worth doing. Feel free to DM.

This is such an interesting pain point, especially for smaller commercial portfolios that are too sophisticated for residential property management software but nowhere near the scale that justifies an enterprise platform.

Coming from the commercial lending side, I’d add one thing to your wish list: clean property-level financial reporting that can easily be exported and shared with a lender.

When an owner is refinancing or acquiring another property, being able to quickly produce a current rent roll, historical income/expenses, lease information, CAM reimbursements and a clear picture of NOI can make the financing process significantly easier.

I’d be interested to hear what you think of PigJet after you’ve used it through an actual year-end CAM reconciliation. That sounds like the real test!

For under 20 units, honestly sticking with QuickBooks and building a dedicated Excel/Google Sheets model specifically for CAM reconciliations is still what 90% of small CRE operators do

I think there’s another way to look at this.

At under 20 units, I’m not convinced the primary question is “which property management platform has the best commercial feature set?”

The harder problem is that the operating information is fragmented.

The lease contains the actual obligations. QuickBooks contains the expenses. The PM system contains the property activity. A spreadsheet ends up becoming the place where somebody manually reconstructs the relationship between all three.

That’s why CAM season becomes painful.

I’d start by pulling the economic terms out of every lease into a structured operating layer: base rent, escalations, recoverable expenses, exclusions, caps, admin fees, base years, gross-up rules, notice dates, renewal options, and reconciliation requirements.

Then I’d make the accounting and property-management systems feed that layer instead of expecting either one of them to be the source of truth for everything.

Once that exists, CAM reconciliation becomes much less of a “software feature” and more of a controlled workflow:

Lease obligation → actual expense → allocation logic → tenant responsibility → amount already billed → true-up → supporting evidence.

That also changes how I’d evaluate the software.

I wouldn’t ask whether it is “commercial” enough. I’d ask whether it can reliably expose and accept the data needed to run that workflow without trapping the portfolio inside the application.

For a small portfolio, I actually think there’s an advantage to keeping the systems relatively simple and putting the intelligence between them rather than buying a giant platform just to get one painful annual workflow under control.

The software can change later. The lease logic, accounting history, operating rules, and decision trail shouldn’t have to.

That’s the part I’d solve first.

@Lance Porter - I saw you left a comment somewhere that I can't get to somewhere. I didn't see enough of it to know what you were going to say, but I did see enough to know how it was going to end.

I went another layer down, because the interesting question isn’t really the cap-rate math. It’s what happens at your trust boundaries.

Your own documentation says payments leave AgenticRentOS for Stripe-hosted or Stripe-managed processing, and then your internal ledger depends on verified provider events or server-side verification coming back. Refunds, reversals, disputes and failures subsequently have to be reconciled.

Your identity layer can depend on Google, Apple or Microsoft. Lease documents become extracted text and summaries. AI features receive selected application context and return generated output. Public-property inquiries can leave the application for an email inbox.

And your own Terms say executed leases, posted accounting records, payment-provider confirmations and official management communications can all be controlling operational records.

That’s the part I’m actually interested in.

Because now you don’t have a UI problem. You have a distributed-state problem.

When information leaves your boundary and comes back, how do you prove that what returned still represents the same tenant, lease, invoice, source version, authorization and human intent that left?

If Stripe returns events late, twice, or out of order, what provides the idempotent effect and authoritative transition?

If a tenant interaction happens in email and materially changes the meaning of an issue, how does that context re-enter the canonical state without somebody simply copying a conclusion back into the system?

If a lease is amended after you extracted its critical dates, what invalidates the old derived state and proves which version every downstream conclusion came from?

If a model receives a snapshot of permitted context, produces a perfectly reasonable answer, and the underlying record changes before that answer is acted upon, how do you detect that the answer is now semantically stale?

Where are the immutable source identifiers, hashes/version lineage, causal event chain, deduplication/idempotency controls, ordering rules, conflict resolution, stale-context invalidation and decision receipts?

Those aren’t hypothetical edge cases created by AI. They’re the ordinary consequences of the architecture your own documentation describes.

And your AI notice actually makes the point for me: you explicitly say model output may be incomplete or incorrect and does not replace the controlling records. Correct.

Which means the difficult product isn’t the assistant.

The difficult product is the provenance and state architecture that prevents information from silently changing meaning as it crosses systems.

Maybe you built that layer. I genuinely couldn’t find it described publicly.

If you did, that is what I’d be interested in comparing notes on — event provenance, state continuity, source authority, context preservation and intent across external boundaries.

Because making several integrations appear inside one dashboard is straightforward.

Proving that the information still means the same thing after it has left your system and come back is the engineering problem.

For under 20 mixed commercial units, I'd stop hunting for a magic residential-first platform that suddenly does CAM well. Most of the pain we clean up for clients is lease-language and process, not missing a Yardi-sized logo.

What usually works at that size is QuickBooks or a clean GL as the books, plus amendment-aware lease abstracts that track current pro-rata share, base year, caps, exclusions, and recovery pools. Map the GL to those CAM pools. Then run quarterly preliminary reconciliations so you're not rebuilding twelve months of tenant math in one ugly weekend.

AppFolio, Buildium, DoorLoop, Rent Manager can help ops, but if CAM true-ups are the bottleneck, buy process first. A spreadsheet bridge is fine temporarily. A year-end archaeology project every January is not.
