My colleague Andrew Bartels just published this interesting take on SAP’s recent results:

Software License Revenues Roar Back In Q1 2010 — And Why Licensed Software Will Co-Exist With SaaS Beyond 2010

Liz Herbert and I will be speaking on this theme at Forrester's IT Forum on May 27 in our session: "Noughty" Software Licensing — Is The Obituary Premature? Andrew is absolutely right. In addition to the points he raises, there are other reasons why perpetual licenses aren’t dead yet, such as the financial results they generate. The new models haven’t yet shown they can generate both high levels of re-investment in R&D and high profits for investors. Many SaaS providers have to spend a large share of their income on sales and marketing to retain existing customers and renew subscriptions. That leaves less money left over to fund innovation or fewer profits than their old-model rivals whose entrenched installed bases guarantee high maintenance renewal rates.

But perpetual license vendors mustn’t be complacent. The SaaS model may prove equally remunerative to the license-plus-maintenance alternative when the providers get bigger. Software buyers can encourage the established companies to learn from their SaaS competitors by insisting on some of that commercial model’s advantages in their own contracts, such as low up-front commitment and cost flexibility.
