A software licensing agreement is the contract that sets the terms under which your customer may use your software: the scope of the license, what the customer can and cannot do with it, the fees, and how your intellectual property stays protected. Aber Law Firm drafts and negotiates these agreements for software and SaaS vendors only, across 650+ clients and 2,500+ deals since 2009, so the agreement is built around your business model instead of a generic form.
There is no standard software license. How you license, perpetual or subscription, on-premise or cloud, per-seat or usage-based, changes which terms matter and which risks you carry. The customer signs the agreement once and rarely reads it again. You live with every word of it on every deal, so getting it right one time, in plain English, pays off across your entire customer base.
What a Software Licensing Agreement Covers
- The license grant. The heart of the agreement: what the customer may do with the software, which users and environments are authorized, and the limits on copying, modification, reverse engineering, and transfer.
- Fees and term. Price, payment timing, the license term, renewals, and what happens to the license when the agreement ends.
- Warranties and support. What you promise the software will do, the disclaimers around everything else, and the support or maintenance you commit to provide.
- Liability and indemnity. Limitation of liability caps and tightly drawn indemnities. We treat uncapped exposure as a red flag every time.
- IP ownership. You keep your software, platform, and IP; the customer keeps its own data. Say it plainly so there is no argument later.
License Models Change the Agreement
A perpetual on-premise license and a cloud subscription are not the same contract, even when the product is similar. A perpetual license grants a lasting right to use a specific version and leans on the license grant and the essential-step rights in 17 U.S.C. Section 117. A subscription grants a right to use the software for the term and falls away when the term ends. If your product is delivered as a hosted service with nothing installed on the customer’s machine, you usually want SaaS subscription terms rather than a traditional license, which we cover in our SaaS contract practice and our cloud services agreement page. Bolting a license-style agreement onto a subscription service creates gaps that surface during enterprise procurement review.
The Clauses That Carry the Risk
Most of the money in a software licensing agreement sits in a handful of clauses. The limitation of liability decides who absorbs the loss when the software fails or data is lost, and an uncapped liability clause can put your whole company at risk on a single deal. The indemnity decides who defends and pays when a third party brings a claim, and we draft these tightly rather than accepting broad, open-ended obligations. The warranty and disclaimer set expectations for what the software does. Your license also rests on copyright: original code is protected under the U.S. Copyright Act from the moment it is written, and where open-source components are linked into your product, copyleft obligations can reach your proprietary code. We align the license grant, the copyright position, and your open-source usage on the IP side through our software copyright lawyer practice.
Plain English Agreements That Help You Sell
Software licensing is not simple, but your agreement does not have to be complicated. We draft simple, clear, plain English agreements that customers can actually read, which tends to shorten the sales cycle. For the full practice, see our software licensing attorney and software attorney overviews, and for a clause-by-clause starting point, our SaaS agreement template checklist. The practice is led by Jeremy Aber, who has focused on software licensing and SaaS contracts for vendors since 2009.
Frequently Asked Questions
What is the difference between a software license and a SaaS subscription?
A software license grants the customer a right to use a copy of your software, often installed on its own systems. A SaaS subscription grants a right to access a hosted service for the term, with nothing installed. The right structure depends on how your product is actually delivered, not on which label is more familiar.
Do I need a written software licensing agreement?
Yes. Without one, the terms of use, the limits on the license, and your liability are left to gap-filling rules you did not choose. A written agreement fixes the scope of the grant, caps your exposure, and protects your IP on every deal.
Can my customer let its affiliates or contractors use the software?
Only if the agreement says so. Authorized-user and affiliate-access language should be defined up front; otherwise you face either an unwanted expansion of the grant or a dispute later about what was permitted.
Does the agreement need to address open-source components?
If your codebase includes them, yes. Copyleft licenses such as the GPL can impose obligations on code that links to them, which can affect what you are able to license to customers. We reconcile your inbound open-source usage with your outbound license terms.
