You're going to use these tools as fires come in. Meaning, when you get too many returns that your head is going to explode, you need a tool for that. When you start losing track of your inventory because its scattered across your garage, you are going to need an inventory management solution to better understand what you have in stock and how to get it to customers. When your customers start asking you "Hey, where's my order?" to the point that it becomes your suppor teams full time job to answer, you're going to want a tool that helps mitigate those tickets by allowing autonomous order lookup, etc.

Investing in operations and logistics tools happens at every stage of your business, but should often be centered around key hires. When you bring in a head of customer support, you may want to give them a tool to streamline their efforts. When you bring in an operations manager, or logistics support, they will likely need a tool. When you bring in a product sourcing team member, they need a tool, etc.

Typically these tools are managed by the operations manager, head ofEcommerce, COO, or you as the CEO.

You're looking to tie multiple data sources together and get the information you need - typically shipping, billing, order, or inventory information into the hands of your team, and your customers, as appropriate.
