They were using standard objects, but it became clear that the unique nature of their inventory required a more tailored approach. I designed and implemented a custom object model that included custom objects for Inventory Items, Suppliers, and Purchase Orders.

I started by conducting a thorough analysis of their business processes and identifying the key relationships between different data points. Then, I created custom objects and fields, ensuring that they aligned perfectly with their workflows. I also developed custom triggers and workflows to automate inventory updates and notifications, reducing manual effort significantly. After deploying the solution, we saw a 40% increase in inventory management efficiency and a substantial reduction in errors, which was a huge win for the client.”
