ERP tiers is how ERP software used to be categorized. Based primarily on client size and software scope, there are three tiers: Tier 1 for enterprises, Tier 2 for mid-sized companies, and Tier 3 for smaller businesses. While the terminology is a little outdated, knowing the different levels can help companies when it’s time to shop for a new ERP solution.
The three tiers are fairly simple to understand:
Some ERP developers also add Tier 4 and Tier 5 to address solutions for even smaller budgets, though this is increasingly uncommon.
In recent years, some vendors have stopped using tiers to categorize their products. This is largely because there are now more ways to scale software without needing to switch products. In the past, a company might start with a Tier 3 ERP and then move up to a Tier 2 or Tier 1 solution. Today, Tier 3 products can grow with the business, removing the need to go out and purchase a replacement software.
Tier 1 refers to any large scale software which can facilitate a high level of functionality. The ERP is intended to be used by large corporations all over the world. These solutions tend to be the most expensive on the market and take longer to implement than lower tiered options.
Tier 2 includes ERP systems which are not quite as all-encompassing as Tier 1 but still offer enough capabilities to cover multinational operations on a wide scale. The total costs are lower than Tier 1 and implementation is faster.
Some Tier 2 solutions are made by the same developers of Tier 1. These smaller solutions are usually industry-specific to provide businesses within certain fields extra functionality.
Finally, Tier 3 covers all the smaller ERP solutions which have lower annual costs. However, this can still be in the thousands. There tends to be a shorter implementation, though this depends on what exactly the business needs. These solutions are recommended for businesses looking for their first ERP system.
There are a few things you need to know to determine which tier you will need:
Fortunately, the actual tier classification is not as important these days. Many ERP systems are able to scale as companies grow, meaning no more switching software. For example, Microsoft has ERP products which fit into all three tiers. Companies can start with Business Central and expand into Finance and Operations without the extra hassle of finding, buying, and implementing a brand new ERP.
Another reason the tier classification system is fading is the rise of software customization. Add-on modules and third-party integrations make it possible to get a higher level of functionality from a Tier 2 or Tier 3 ERP without the need to purchase a Tier 1.
Two-tier ERP refers to the practice of mixing ERP from two different tiers for different business purposes. Specifically, the idea is to take a Tier 1 ERP system at the corporate level while allowing subsidiaries or divisions within the company to operate using a different Tier 2 ERP solution. This can provide budgetary savings by cutting down on the total number of user licenses for the larger products.
An ERP trend in recent years has been mixing ERP from any level to create a customized, hybrid system. Smaller and mid-size companies can get by by mixing Tier 2 and Tier 3 solutions to essentially equal the functionality of a Tier 1 product.
