Lease accounting software for CPA firms: 5 options compared

For a CPA firm, the deciding factor is not the calculation engine, it is the multi-client model: whether one login manages every client entity separately, whether the client can be given their own access without seeing other clients, and whether the standards your client base actually reports under are covered. Crunchafi, NetLease from Netgain and Black Owl Systems all sell dedicated firm tiers. None of the three publishes a price. That last point shapes the whole evaluation, so it is worth being clear-eyed about it before you book four demos.

This is a buying guide for firms that produce ASC 842, IFRS 16 or GASB deliverables on behalf of clients, rather than for a single company closing its own books. Vendor facts below were checked on each vendor's own site in September 2026. Last updated September 2026.

What does lease accounting software for CPA firms need to do differently?

A firm buys on a different axis than a corporate controller does. The controller needs one entity done correctly. The firm needs forty entities done repeatably, by staff who rotate, under review, with a trail that survives peer review and an audit.

Three requirements separate the firm products from the corporate ones. The first is entity separation with shared administration: one firm dashboard, strict walls between client records, and the ability to add an engagement without a new contract. The second is dual access, meaning the client can log in to their own data while the firm retains control, which removes the endless spreadsheet emailing that eats realization. The third is standards breadth, because a firm does not get to choose its clients' reporting frameworks.

Pricing structure matters more than pricing level here. Per-lease pricing is predictable for a firm with many small clients. Per-entity pricing punishes exactly that profile. Ask which unit the meter runs on before you ask what it costs.

Standards coverage is what each vendor states publicly, not an assurance that a given engagement is in scope. Confirm the specific standard and client type in writing before you commit a busy season to it.

How much does lease accounting software for CPA firms cost?

Nobody publishes a rate card. Every vendor above quotes, and the only structural detail any of them states openly is Crunchafi's, which says lease accounting is priced per lease per year. That is genuinely useful, because per-lease is the unit that scales with a firm's client mix rather than against it.

You will find specific dollar figures on review and comparison sites. Treat them with real suspicion. Those numbers are frequently reconstructed from a single customer's quote years ago, or invented outright, and for quote-only vendors the ranges published across different directories routinely disagree by an order of magnitude. A spread that wide is not a price, it is the absence of one. Our lease abstraction software pricing comparison records vendor by vendor who actually publishes figures and who does not.

What you can control is the shape of the quote. Ask for four lines broken out separately: the platform subscription, implementation, the per-lease or per-entity unit and where it steps, and the cost of getting existing client leases into the system. The fourth line is the one that surprises firms, and it is covered below.

Which product fits which kind of firm?

The honest answer is that the differences are narrower than the marketing suggests, and two questions decide most shortlists.

Do you serve government or public sector clients? If yes, GASB coverage is not optional and it removes Black Owl from consideration, since its own site lists ASC 842, IFRS 16 and ASPE 3065 without GASB. Crunchafi lists the widest GASB coverage of the group, including 94 and 96, which matters for firms with municipal utility or SBITA work. If you serve Canadian clients or entities reporting under ASPE, Black Owl is the one of the group that names that standard explicitly.

Do your clients live in QuickBooks? Most small and mid-market clients do, and NetLease connects to client QuickBooks Online accounts directly, which shortens the journal entry loop considerably compared with exporting and re-importing. If your client base is on larger ERPs, Black Owl names SAP, Oracle and Microsoft Dynamics integrations, and it holds SOC 1 Type 2 and SOC 2 Type 2 certifications, which will matter the first time a client's IT function reviews your subservice organizations.

Firm size matters less than people expect. All of these handle a hundred client entities. What differs is whether you are billed in a way that makes an eight lease client worth taking on. For the underlying accounting rather than the tooling, our ASC 842 implementation guide covers what the standard requires, and Crunchafi compared and FinQuery compared go deeper on those two specifically.

What none of these platforms do: read the client's leases

Every product above starts from lease data that already exists in structured form. None of them reads the client's lease PDFs and produces that data. Someone still has to open each document and pull out the commencement date, the rent schedule, the escalation method, the renewal options and the incentives. In a firm, that someone is billing hours, and it is the single largest cost in a first-year 842 engagement.

This is not a gap the vendors hide. Crunchafi sells Data Extraction as a separate product from Lease Accounting, priced separately, with its own sales conversation. That is a fair reflection of reality: extracting terms from documents and calculating schedules from terms are two different jobs, and firms routinely buy the second and then absorb the first as staff time.

The math is unforgiving on a backlog. A client with sixty leases, at an hour or more per lease for a careful manual abstract with amendments reconciled, is a week and a half of staff time before a single journal entry exists, repeated for every client you onboard. Running the documents through a commercial lease agreement data extractor first turns that into a review task, and because every extracted value links back to the clause it came from, a reviewer confirms an abstract rather than building one. Amendments matter most here: the current rent on a ten year lease usually lives in the third amendment, not the original, and our note on amendments versus addenda explains why a stale abstract misstates it. If you are pricing the work rather than the tool, the lease abstraction cost guide has the per-lease math for all three approaches.

How long does implementation take before busy season?

Plan on weeks, not days, and plan backwards from your first client close rather than forwards from the contract date. The software configuration itself is rarely the constraint. The constraint is client data: chasing lease documents from clients who cannot find them, resolving which amendment governs, and agreeing on discount rate policy per client.

The second constraint is people. A firm rolling out a new subledger has to get seniors and associates fluent in it before the work arrives, and the vendor's own live sessions cover the product rather than your firm's engagement workflow around it. Firms that treat this seriously build a short internal course covering their own review checklist and standardized workpapers, and run every staff member through it, which is straightforward enough with a platform to train and certify the whole team and considerably cheaper than discovering the gaps in February.

Sequence the pilot deliberately. Take one mid-sized client with clean documents, run it end to end including the audit deliverable, and only then onboard in volume. Firms that start with their messiest client conclude the software is the problem when the documents were.

The short version

If your client base includes government entities, Crunchafi's GASB breadth is the strongest of the group. If your clients run on QuickBooks Online, NetLease's direct connection is the practical advantage. If you need ASPE 3065 or lessor accounting alongside lessee, Black Owl names both. Every one of them will quote rather than publish, so run the same four line quote request past all three and compare the shapes, not the headline.

Then budget separately for the documents. The platform decision is the visible one, but the lease abstraction underneath it is where the hours actually go, and it is the part you can compress the most. You can extract a client lease and see the output structure before you commit to anything.
