A company is looking to enhance its Salesforce environment by integrating a new app that automates lead management. They have identified three potential apps from the AppExchange. Each app has different features, pricing models, and user reviews. The company needs to evaluate these apps based on their compatibility with existing Salesforce features, user feedback, and total cost of ownership (TCO) over a three-year period. If App A costs $1,200 per year, App B costs $1,500 per year, and App C costs $900 per year, and they anticipate needing additional training for App B costing $600, which app should the company choose based on the lowest TCO, considering they also value user feedback highly, which is best for App A?
