When to Opt for Custom Purchase Order Software

ScienceSoft recommends building a custom purchase order solution in the following cases:

You need a purchase order solution providing specific features, for example, AI-powered spend forecasting.

You operate in highly regulated industries (e.g., healthcare, government sector, defense) and need purchase software to meet specific compliance and security requirements. For example, in our project for the US hospital system, we developed a custom purchase management solution compliant with strict HIPAA regulations.

You want to avoid costly and effort-consuming integration of buying software with your corporate systems, including legacy (accounting software, an inventory management system, a vendor portal, etc.).

You have large teams involved in purchasing processes and want to avoid a considerable subscription cost for a platform-based purchase ordering system, which scales with the number of users.
