The bigger the software publisher, the more often we see that end users expect that they are not able to change anything in the standard terms and conditions offered by the publisher. But when it comes to your specific situation, those standard terms and conditions may not be fit for your business needs. There are typically a number of drivers that should be taken into account when you start to negotiate: what type of company are you (e.g. public sector organizations usually have a different need than commercial organizations), what type of licenses/subscriptions are you planning to purchase, what is the total deal volume (from a CAPEX and OPEX perspective), what is the total term you are able and willing to commit to, what are the countries you are planning to use the software for, etc.
Not looking into the specific terms and conditions of your agreement may result in issues at a later stage. Think for example about the situation in which you may have multiple subsidiaries across the globe. Are these legal entities (directly or indirectly controlled by your organization) defined correctly in your “Customer Definition”?
