In the late 80's Solomon Software (firm that developed Dynamics SL) was still a market leader along with Great Plains (now Dynamics GP).
The firm was having such good success that they decided to create a higher end product for larger clients. This too was going to be a DOS-based product but have rich multi-company and multi-currency features, national accounts and ease of use functions for larger firms.
The future looked very bright for this product as Solomon was making a lot of money and had an amazingly talented Business Analyst in charge of the product's design.
Unfortunately the product kept getting delayed from being released because this brilliant person kept coming up with "one more idea" to make it even better. The product in the end started running up against competitor's that had similar ideas but shipped product sooner, as well as the onslaught of Windows-based products that were being developed.
To me a SaaS model does the exact opposite. What SaaS-based ERP developer Intacct offers is "features right away". Since the software is being constantly improved and moved into production, users don't have to wait for "the big release". Users get constant improvement each quarter with releases that are moved into production for everyone.
Personally I like Dynamics CRM better than Salesforce for CRM. The product enforces more standards so that users have similar experiences rather than allowing each individual user to effectively use the software however they'd like. I also like the option of being able to run Dynamics CRM on premise or in the cloud.
What I miss having selected the on-premise model are all the improvements that Microsoft made with Dynamics CRM 2011. If I were running CRM in the cloud, I would have all of those improvements already instead of waiting for a convenient time to upgrade from Version 4.
Salesforce used to tell us which weekend they were going to do our upgrade and it was not disruptive at all. It was nice in fact to have new features without having to test any of them or wonder if they would work.
So I see this SaaS model with automatic upgrades as something that is remarkably NOT disruptive but productive. While these automatic upgrades are going to cause us as consultants to lose upgrade services revenue, I believe that for clients of products like Intacct-it is a less disruptive option that ensures that clients get their value each year for the fees they pay us to keep current with software.
If you look below at the graph of Intacct's tenure in business, you can see, this is a long time to offer users a product where the user never had to do anything to upgrade the product they were using.
Because we are allowing our hardware to age with the expectation we will move everything to the cloud here at Boyer, we are running into more and more "issues". We are moving more and more to the cloud. This year ERP, next year MS CRM and Exchange, Office 365 in 2014. 99.8% uptime without paying for the inconvenience or disruption of upgrades is looking pretty good to me.
How about you?
