AppExchange, Salesforce's marketplace, offers a myriad of ready-to-use apps. But there are instances where a custom solution might be a better fit.
Before deciding, conduct a thorough needs assessment. If your requirements are highly specialized, building a custom solution, though resource-intensive, might offer better long-term value. On the other hand, if an AppExchange app meets most of your needs, purchasing and customizing it could be more cost-effective.
When considering the build vs. buy dilemma, factor in not just the initial costs but also long-term maintenance, updates, and scalability.
