SaaS vs On-Premise Software: Which Software Business to Buy

SaaS software businesses sold for roughly 21% more than non-SaaS software businesses in 2024, down from a premium of more than 40% between 2015 and 2020. That is the finding from Aventis Advisors, which compared SaaS transactions against on-premise vendors, API and SDK platforms and software component companies across 543 disclosed deals since 2015. For a buyer choosing between two software companies for sale, the practical read is that the subscription label is worth far less than it used to be, and the discount on a well-run licensed-software business is often larger than the risk that comes with it.

This is a question worth getting right, because the two models fail in completely different ways. Below is what actually separates them at the point of purchase, using figures read firsthand in August 2026.

What the valuation gap actually looks like

Aventis publishes its SaaS valuation study annually, and the 2026 edition was published on 1 April 2026. The private M&A sample is 543 transactions with a disclosed revenue multiple and 232 with a disclosed EBITDA multiple.

Read the last three rows together and the story is clear. In 2021 non-SaaS software briefly reached 5.3x revenue as buyers with capital to deploy went looking outside a crowded SaaS bracket. The premium never fully returned to where it was. Aventis gives two reasons: competition pushed valuations up for hybrid and on-premise models, and traditional vendors have been converting to cloud delivery and subscription pricing themselves, which blurs the line the premium was supposed to price.

What is the difference between SaaS and on-premise software

SaaS is delivered from the vendor's own infrastructure and billed as a recurring subscription, so revenue renews by default and the vendor carries the hosting cost. On-premise software is installed on the customer's own servers under a perpetual license, usually with an annual maintenance or support contract attached. The distinction that matters commercially is not where the code runs, it is which party has to act for revenue to continue.

Where each model actually breaks

A SaaS business fails through churn. Revenue leaks continuously and quietly, and if net revenue retention sits below 100% the business needs new customers just to stand still. The compensating strength is that the failure is visible in a dashboard within weeks.

A licensed-software business fails through concentration and inertia. Maintenance revenue from a handful of large accounts can look rock solid for years and then vanish in a single renewal cycle when one customer decides to migrate. The failure is slow to appear and fast to arrive.

Is a SaaS business worth more than an on-premise one

Usually yes, but by about 21% rather than the 40% or more the market paid a decade ago, and only if the recurring revenue is genuinely recurring. A SaaS business with 30% annual gross churn and a single enterprise customer at 40% of revenue is not worth a premium over a licensed vendor with ten stable accounts and a 90% maintenance renewal rate. The label is a starting point for pricing, not a conclusion.

The gross margin question decides more than the model does

The cleanest way to compare two software companies of different models is to ignore the label and look at what is left after delivery. Median software gross margin sits around 80% in current benchmark data, and the distance between a business at 80% and one at 55% is worth far more than the difference between a subscription and a license.

This is where SaaS acquisitions surprise first-time buyers. The seller's profit and loss statement shows hosting as one line, and that line is often understated because the founder is running on startup credits, a legacy pricing agreement, or reserved instances that expire. Before you agree a price, get a read-only view of what the infrastructure actually costs across the cloud and third-party SaaS the product depends on, then re-run the gross margin yourself. A product that looks 78% gross margin on the seller's spreadsheet and 61% on the actual bills is a different business at a different price.

On-premise businesses have the mirror-image trap. Their delivery cost is low because the customer runs the servers, but support and professional services can quietly consume the margin, and those costs usually sit in the founder's own unpaid hours.

Which software business should a first-time buyer buy

Buy the one you can operate. That sounds obvious and it is the most commonly ignored rule in this market. A SaaS business needs someone who can ship a fix, manage uptime and run a retention motion. A licensed-software business needs someone who can hold an enterprise relationship together and negotiate a renewal. Those are different jobs and most buyers are good at one of them.

If you are choosing purely on price and you can carry enterprise relationships, the non-SaaS bracket is where the arithmetic currently favors the buyer, because fewer people are bidding. If your edge is product and iteration speed, pay the premium for the subscription model and spend your diligence budget on churn cohorts rather than on the contract stack. Either way, our guide to software companies for sale shows which venues list each model and what a buyer pays at each one.

How to verify the revenue in either model

The verification work is not the same for the two models, and using a SaaS checklist on a licensed vendor is how buyers miss the important risk.

For SaaS, insist on live read-only access to the payment processor rather than exported spreadsheets, because exports are trivial to edit. Reconcile the processor against bank deposits for the same period, then pull churn by cohort rather than as a single blended number. The blended figure hides the pattern where new customers leave quickly and a few old ones prop up the average. Our walkthrough of how to verify MRR before buying a SaaS covers the specific access to ask for.

For on-premise and licensed software, the contracts are the asset. Read every material customer agreement for change-of-control clauses, because a clause that lets a customer exit on a change of ownership turns your purchase price into a negotiating position. Check whether maintenance auto-renews or requires a signature, when each contract expires relative to your closing date, and whether any customer has already given notice. Then check code ownership: contractor agreements without an IP assignment clause are common in older software businesses and expensive to fix afterward.

Both models share one check. Find out whether the product ships without the founder. If the only person who understands the codebase is leaving after a 30-day handover, you are buying a liability with revenue attached, whatever the delivery model. That is the risk our note on key person risk in a SaaS acquisition deals with in detail.

What multiple should I pay for a non-SaaS software company

Start from the SaaS median that fits the deal size, then discount it by roughly the premium Aventis measured, and adjust from there on the specifics. In the private M&A sample the SaaS median is 4.5x revenue, so a comparable non-SaaS business sits nearer 3.5x to 3.7x on the 2024 relationship. Below roughly $5M in enterprise value the market usually switches basis entirely and prices on owner profit instead, where Empire Flippers reported a typical 26.4x multiple of average monthly net profit on its public scoreboard on 1 September 2026, which is about 2.20x annual profit by our arithmetic.

Do not treat any of these as a quote. They are medians from samples of completed transactions, and the quartiles on the SaaS sample run from 2.4x to 8.1x, which tells you the median alone explains very little. Growth rate, retention, gross margin, customer concentration and founder dependence move a specific business within that range far more than its delivery model does. Our breakdown of SaaS valuation multiples works through how each driver shifts the number.

The short answer

SaaS still commands a premium and it is now a modest one. Buy the subscription model if you can run a product and defend retention, and pay about 21% more for the privilege. Buy the licensed or on-premise model if you can hold enterprise relationships together, and collect the discount that exists mainly because the bracket is unfashionable. In both cases the number that decides whether the purchase works is not the multiple you paid, it is the gross margin you can actually verify and the concentration you inherit.
