One publishes every price down to the add-on. The other prints Contact Sales in all five places a number would go. Neither ships self-serve AI lease abstraction. Abstract a real lease here free first.

Compiled from each vendor public product, pricing and sitemap pages, checked on September 4, 2026. The headline difference is not a feature. It is that one of these two vendors will tell you what it costs before you talk to anyone, and the other will not.
| Software | Core job | AI lease abstraction | Published price | Free to try | Best fit |
|---|---|---|---|---|---|
| LeaseAbstractors This tool | Turn lease PDFs into structured data | Yes, every field links back to its source clause | Published on our pricing page | Yes, no signup and no demo | Any team holding lease PDFs that needs the data out of them |
| Black Owl Systems | Lease accounting for finance teams who own the close, lessee and lessor | None. No abstraction page exists anywhere on its site | No dollar amount. All five tiers read Contact Sales | No, book a demo | Equipment-heavy portfolios, multi-standard reporting and CPA firms |
| iLeasePro | Lessee lease accounting and lease management under ASC 842 | As a human professional service, not as self-serve AI | Yes. iLeaseXpress is 149 dollars per month up to 15 leases | Yes, a 15-day free trial | A private US company with roughly 25 to 500 leases reporting under ASC 842 |
Verified against each vendor public pages on September 4, 2026. The Black Owl pricing page returns zero dollar amounts when the raw HTML is searched for a dollar sign, and prints Contact Sales five times. The iLeasePro pricing page prints a full ladder including named add-on prices. iLeasePro is the rare vendor in this category that publishes real numbers, and that is worth saying plainly even though it competes with us.
These two overlap more than most pairs in this category, because both are lease accounting products aimed at the lessee close. Six questions separate them, and five of the six can be answered from public pages before you sit through a demo.
This is the cleanest split between the two. iLeasePro publishes a price ladder: iLeaseXpress at 149 dollars per month for up to 15 leases, a separate contract management ladder running from a free tier up to 9,600 dollars per year for 500 contracts, and named add-on prices such as 1,208 dollars per year for portfolio management and 300 dollars per year for enterprise single sign-on. Black Owl names five tiers, Small Business, Large Companies, Enterprise, CPA Essentials and CPA Advanced, and prices every one of them Contact Sales. If your procurement process needs a budget figure this quarter, only one of these two can give you one today.
Black Owl publishes industry pages for aviation, oil and gas, transportation and logistics, manufacturing and construction, which is a lease population made of rigs, fleet and plant. iLeasePro sells to commercial real estate operators and describes office, retail, industrial and mixed-use property types. If a large share of your ASC 842 population is equipment rather than property, that shifts the answer toward Black Owl regardless of price.
Black Owl runs dedicated pages for ASC 842, IFRS 16 and ASPE 3065, the last of which covers Canadian private companies, and it offers native lessor accounting alongside lessee accounting. iLeasePro is scoped to the lessee side under ASC 842 and IFRS 16. A US private company reporting only under ASC 842 does not need the extra standards, and paying for breadth you will never file is a common way to overspend here.
iLeasePro sizes itself openly for roughly 25 to 500 leases and splits its product at 15 leases, with iLeaseXpress below that line and the full platform above it. Black Owl does not publish a lease count band at all, so fit has to be established in a sales conversation. Knowing your own count before either call saves a round trip, and it is the single number both vendors will ask for first.
Neither product removes this step for you. Black Owl ships no abstraction capability at all. iLeasePro offers lease abstraction as a professional service delivered by its own team, described on its site as certified professionals with commercial real estate expertise, with no AI named on that page and no price published for the service. Either way, somebody reads the leases and types the fields, and the cost of that work is usually invisible in the software quote.
Black Owl runs two editions built for accounting firms, CPA Essentials and CPA Advanced, which signals a practice serving many client engagements from one login. iLeasePro is aimed at the company that holds the leases and has to report them. If you are a firm abstracting client leases and handing back schedules, that firm-side packaging matters more than the per-seat price.
You can settle most of this from public pages and one uploaded lease, before either vendor puts you in a sales cycle.
Write down the total, then the split between real estate and equipment. Those two numbers decide more of this than any feature list, and both vendors will open with the same question.
Upload your three most awkward leases here and get the structured fields back in minutes. That gives you a real data set to test both platforms against, instead of the tidy sample lease a vendor brings to a demo.
The numbers are public, so calculate your annual cost yourself, add-ons included. That gives you a concrete figure to hold the Contact Sales quote against when Black Owl comes back with one.
Get the abstraction answer in writing, including who does the work, how long it takes and what it costs. This is the line item that most often turns a cheap quote into an expensive year.
Direct answers to the questions people search before choosing between these two, with every vendor claim checked against public pages on September 4, 2026.
Black Owl Systems and iLeasePro both sell lease accounting software to US companies reporting under ASC 842, which is why they land on the same shortlist. They diverge on two things a buyer can check in ten minutes: whether the vendor will publish a price, and what the product does about getting lease data into the system in the first place. iLeasePro publishes a full price ladder. Black Owl publishes none. Neither one abstracts leases with self-serve AI.
iLeasePro publishes real numbers. iLeaseXpress costs 149 dollars per month for portfolios up to 15 leases and includes a 15-day free trial with no setup fees. The full iLeasePro platform covers unlimited leases. Add-ons are priced separately, at 1,208 dollars per year each for portfolio management and document management, and 300 dollars per year each for multi-factor authentication and enterprise single sign-on. Longer commitments carry a discount, 10 percent at two years and 15 percent at three. A separate contract management product runs from a free tier for up to 5 contracts through 2,400 dollars per year for 50 contracts, 4,800 for 150 and 9,600 for 500.
Black Owl does not publish a price. Its pricing page names five tiers, Small Business, Large Companies, Enterprise, CPA Essentials and CPA Advanced, and every one of them reads Contact Sales. Searching the raw HTML of that page for a dollar sign returns nothing. The page is headed Transparent Plans for Every Team Size, which makes the absence of numbers more striking rather than less. You will get a figure only after a sales conversation, and it will be scoped to your lease count and modules.
No. Black Owl Systems ships no lease abstraction capability, and there is no lease abstraction page anywhere on its site. Its pricing page does not contain the word abstract at all. The product assumes your lease data already exists in structured form and takes over from there, handling classification, schedules, journal entries and disclosure. Getting the terms out of the PDFs is work you or somebody you pay does before Black Owl becomes useful.
Yes, but as a human service rather than software you run. iLeasePro sells lease abstraction as a professional service, describing a team of certified commercial real estate specialists who read the leases and deliver summaries formatted for its own platform or another lease accounting system. That page names no AI and publishes no price. So the answer depends on what you are shopping for: if you want a vendor to do the reading, iLeasePro will quote it, and if you want to upload a lease and get fields back yourself in minutes, that is a different kind of product.
Both handle ASC 842 competently, so the tiebreaker is usually scope rather than compliance. Choose Black Owl if you also report under IFRS 16 or Canadian ASPE 3065, if you need lessor accounting in the same system, or if a meaningful share of your leases are equipment. Choose iLeasePro if you are a private US company filing only under ASC 842 with roughly 25 to 500 real estate leases and you want the price before the call. Neither choice solves the data entry problem, which is worth settling separately.
Yes. iLeaseXpress includes a 15-day free trial with no setup fees and the option to cancel at any time, and the separate contract management product has a permanently free tier for up to 5 contracts. Black Owl publishes no trial of any kind and routes every plan through a sales conversation. Among the lease platforms we have checked, a published self-serve trial remains unusual, which makes it a reasonable thing to weigh.
Lease accounting software calculates and reports: it classifies leases, builds amortization schedules, posts journal entries and produces disclosures once the lease terms are already in the system. Lease abstraction software does the step before that, reading the signed PDF and pulling out commencement dates, base rent, escalations, renewal options and critical dates as structured fields. Black Owl and iLeasePro are both accounting products. If you have a stack of unabstracted leases, you need both kinds of tool, and our AI lease abstract generator handles the extraction half.
iLeasePro, clearly and by a wide margin. Across the fifteen lease platforms we have priced this year, iLeasePro is one of very few that print real dollar figures for the main product rather than routing everyone to sales. Black Owl sits with the majority that publish none. That is not by itself a reason to buy iLeasePro, since published pricing tells you nothing about whether the software fits your portfolio, but it does mean you can budget honestly before you spend a month in evaluation. We keep the wider picture on the best lease abstraction software comparison, and the rest of the Black Owl matchups on the Black Owl Systems competitors page.

Talk to our teamNeither does it as self-serve AI software. Black Owl ships no abstraction capability at all. iLeasePro offers abstraction only as a human service its team performs and quotes separately. If you want to upload a lease and get structured, source-linked fields back in minutes, that is the gap LeaseAbstractors fills, and you can test it on your own lease before choosing either accounting platform.
Unknown, and that is the honest answer. iLeasePro publishes its ladder, starting at 149 dollars per month for up to 15 leases. Black Owl publishes nothing, so no comparison is possible until you have a quote in hand. Price the iLeasePro ladder against your own lease count first, then hold the Black Owl quote against that number.
No. Black Owl runs dedicated pages for ASC 842, IFRS 16 and ASPE 3065, and there is no GASB page of any kind on its site. Public sector entities reporting under GASB should rule Black Owl out early rather than discover this in a demo.
Black Owl, yes. It runs separate lessee and lessor pages and treats native lessor accounting as a distinguishing feature. iLeasePro is scoped to the lessee side. If you sit on both sides of leases, that difference alone usually decides the shortlist.
Every figure here was read from each vendor own pages on September 4, 2026, including a raw check of the Black Owl pricing page for dollar amounts. Vendors change prices and retired price cards linger on third-party directories, so treat any number you find elsewhere with suspicion and confirm against the vendor own site.

Ask a questionEach plan includes a monthly allowance of pages, and the number you get depends on which AI model you choose at extraction time. Base AI processes pages faster; Pro AI delivers the highest field-level accuracy. Your allowance resets on your billing anniversary each month, unused pages do not roll over. A typical commercial lease runs 20 to 60 pages including amendments, so the Starter plan's 2,500 Base AI pages cover roughly 40 to 120 leases a month.
Once your included pages are used up, extraction pauses until the next billing cycle. You can upgrade your plan at any time mid-month, the higher allowance kicks in immediately and you are only charged the prorated difference for the remainder of the period.
Yes. You can switch from monthly to yearly billing at any renewal date to lock in the 50% discount. If you switch mid-cycle, the new rate takes effect at the start of your next billing period. Annual plans are non-refundable after the 14-day cancellation window.
All plans export to Excel XLSX and CSV. Plus adds QuickBooks (QBO) export and financial reports. Pro and Enterprise unlock JSON output via REST API and webhooks so you can push structured data directly into any ERP, RPA platform or internal system.
We do not use your documents to train or improve our own models, and files are encrypted in transit (TLS 1.2+) and at rest (AES-256). Extraction runs through a third-party model provider, so review their terms if your policy requires a contractual no-training commitment. You control retention: documents can be deleted from the workspace at any time, and we will remove everything on request.
Enterprise plans are tailored to your organisation's document volume, compliance requirements and integration needs. Pricing is based on committed monthly page volume with volume discounts at scale. Contracts include a Data Processing Agreement (DPA), custom security review support where required, and dedicated infrastructure options. Contact our sales team to get a custom quote.
