Lease abstraction services and lease abstraction software solve the same problem two ways. An outsourced service charges a per-lease rate quoted on request and returns abstracts in days, with a human owning every field and your leases emailed out to a vendor. AI lease abstraction software returns the same abstract in minutes for a fraction of the cost, keeps the documents in your own account, and asks your team to review the flagged values. The right choice comes down to volume, turnaround, document sensitivity, and how much in-house review you want to own. Most teams now run software for the bulk of their volume and keep a service on call for the genuinely hard outliers. Upload a lease below to see the software side free.

Use this as a decision framework. For each thing that actually drives the choice, here is how an outsourced abstraction service compares to AI abstraction software, and which one to lean toward.
| What drives the choice | Outsourced abstraction service | AI abstraction software |
|---|---|---|
| Cost per lease | A per-lease rate quoted on request, billed per document or per project | A fraction of that on a usage or subscription model, dropping further at volume |
| Turnaround | Days to weeks, set by the vendor queue and the size of the batch | Minutes per lease, a whole portfolio in one batch on your own schedule |
| Who does the review | The vendor abstracts and self-checks; you spot-check what comes back | The software abstracts and flags low-confidence fields; your team reviews those |
| Document control | Leases are emailed or uploaded to a third-party vendor | Leases stay in your own account, never sent to an outside service |
| Handling odd, negotiated leases | Strong, a human reads bespoke language and owns the judgment calls | Strong on standard fields, flags the unusual clauses for your reviewer |
| Scaling with volume | Scales only as the vendor adds people; price scales with it | Scales instantly, marginal cost per lease keeps falling |
| Best fit | A small batch of unusual leases where you want a human owning every field | The bulk of normal volume and any high-volume or recurring portfolio |
Figures reflect typical US commercial lease abstraction as of June 2026 and vary by lease complexity, amendments, and vendor. Per-lease service pricing from published industry ranges; software accuracy on standard fields with human review of flagged values.
The decision is rarely all-or-nothing. Walk through the four questions that actually settle it, and most teams land on software for the volume with a service held in reserve for the outliers.
A handful of one-off leases a year can go to a service. Anything recurring, or a portfolio, tips hard toward software because the per-lease cost and turnaround both collapse.
If you are clearing a data room on a closing date or refreshing a rent roll this week, a multi-day vendor queue is a non-starter. Software returns abstracts in minutes.
If your leases cannot leave your environment, a service that requires emailing documents out is hard to clear. Software keeps every lease in your own account.
A service hands you finished abstracts to spot-check. Software hands you a draft with the risky fields flagged. Pick the workflow your team actually wants to run.
At the per-lease rates outsourced services quote, a 500-lease book runs into five or six figures. The same volume on software is a small fraction of that, which is why the switch happens fast.
The strongest setup is software for the bulk of normal leases and a service reserved for a small batch of unusual, heavily negotiated outliers. They are not mutually exclusive.
Three steps from a lease PDF to a structured, source-linked abstract, with no order form, no email handoff, and no vendor turnaround queue.
Drag in the lease PDF, a scan, or a photo. Amendments, commencement letters, and exhibits go in the same upload so the abstract reflects the lease as amended.
Tip: Try one lease free in the tool above and compare it to a service quote.
OCR reads the documents, then AI extracts rent and escalations, critical dates and options, recovery terms, and use and assignment provisions into one structured abstract.
Check the flagged low-confidence fields, then export to Excel, CSV, or JSON for a rent roll, abstract chart, or model, with every value linked to its source clause.
Any team that reads commercial leases and is deciding whether to send them out to a vendor or run them through software in-house.
Buyers on a closing timeline who cannot wait on a vendor queue and need every lease abstracted the same way, fast.
Teams with recurring abstraction work where per-lease service fees add up quickly across a portfolio.
Data custodians clearing a backlog who would rather own the review than pay a service per document forever.
Credit teams who need consistent terms across a collateral pool without emailing borrower leases to a vendor.
A lease abstraction service is people. You send the leases out, a team of trained abstractors reads each one, records the fields, self-checks the work, and sends finished abstracts back days later, billed per lease or per project. Lease abstraction software is a tool you run yourself: AI reads the documents in minutes, fills the same fields, flags the values it is unsure about, and leaves the review to your team. The service takes the work off your plate entirely but costs more per lease, takes longer, and requires emailing confidential leases to a vendor. The software is faster and far cheaper per lease and keeps the documents in your own account, with the trade-off that your team owns the final review. For the tool itself, see our lease abstraction software overview, and for the outsourcing side in depth, lease abstraction services.
Outsourced abstraction is billed per lease at a rate that depends on complexity and amendments. A handful of leases a year is a small bill. A 500-lease portfolio is a six-figure project that takes weeks. The same volume on software runs on a usage or subscription model that drops to a small fraction of that per lease and returns the abstracts in minutes, which is why the switch tends to happen the moment volume grows past a few one-off documents. The deeper cost and speed comparison against doing it by hand is in manual vs automated lease abstraction, and a per-lease breakdown sits in how much lease abstraction software costs.
A service earns its premium on a small batch of unusual, heavily negotiated leases where the value is in a human reading bespoke language and owning every judgment call, and on the genuinely hard outliers most portfolios contain a few of. If you have ten strange ground leases with decades of amendments and no in-house bandwidth to review, paying a person to own them can be worth it. The mistake is sending an entire normal portfolio to a service out of habit, paying per-lease fees and waiting days when software would clear the same book in an afternoon at a fraction of the cost. Match the tool to the lease, not the whole portfolio to one tool.
The strongest setup is not services or software, it is software for the volume and a service held in reserve for the outliers. Run the bulk of normal leases through software in-house so you control turnaround, cost, and document custody, and keep a vendor relationship for the handful of leases that genuinely need a human owning every field. That way a closing-timeline data room never waits on a queue, a rent roll refresh happens the same week, and the per-lease cost across the portfolio stays low. If you are weighing the outsourcing decision itself, our guides on whether you should outsource lease abstraction and the trade-offs of in-house vs outsourced lease abstraction walk through it.

Talk to our teamA lease abstraction service is an outsourced team of people who read your leases and return finished abstracts in days, billed per lease at a rate quoted on request. Lease abstraction software is an AI tool you run yourself that abstracts the same fields in minutes for a fraction of the cost and leaves the review of flagged values to your team. The service takes the work off your plate entirely; the software is faster, cheaper, and keeps documents in your own account.
Yes, in almost every case at volume. Outsourced services charge a per-lease fee, so a 500-lease portfolio runs into five or six figures. Software runs on a usage or subscription model that drops to a small fraction of that per lease and keeps falling as volume grows. A service can still make sense for a handful of one-off, unusual leases, but for recurring work or a portfolio, software is far cheaper.
Outsource when you have a small batch of unusual, heavily negotiated leases where the value is in a human reading bespoke language and owning every judgment call, and you have no in-house bandwidth to review them. For the bulk of normal volume, any portfolio, and anything on a deadline, software is faster, cheaper, and more consistent. Most teams use software for the volume and reserve a service for the genuinely hard outliers.
For standard commercial lease fields, yes. AI lease abstraction reaches roughly 92 to 98 percent accuracy, at or above a typical manual first pass, and flags low-confidence values for review. Every field links to its source clause, so your team verifies the high-stakes terms in seconds rather than re-reading the lease. You keep a human in the loop on the fields that carry risk and skip the days of waiting on a vendor.
Software abstracts a lease in minutes and a whole portfolio in one batch on your own schedule. An outsourced service typically takes days to weeks, set by the vendor queue and the size of the batch. The turnaround gap is what makes software the only practical choice for an acquisition data room on a closing date or a rent roll refresh that has to happen this week.
Yes, and most teams do. Run the bulk of normal leases through software in-house so you control turnaround, cost, and document custody, and keep a service relationship for the small batch of unusual leases that genuinely need a human owning every field. Matching the tool to the lease, rather than sending the whole portfolio to one or the other, gives you the lowest cost and the fastest turnaround.
No. With software your leases stay in your own account and are never emailed to an outside vendor, which is a key difference from a service that requires uploading or emailing confidential documents out. The platform encrypts documents in transit and at rest, and we do not use your leases to train our own models, so document custody stays with you. We hold no SOC 2 attestation today.

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 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.
