When looking for a tool that fits with your store, you should prioritize for these 6 questions:
1. Is it built for Ecommerce?
If not, it may be missing key integrations and features. We want solutions that understand the unique problems of Ecommerce, because they aren't the same as B2B...
2. What is their focus metric?
Find the one metric this tool "promises" to increase and tie that back to the value it will provide to your business, hopefully directly back to revenue. At the worst, tie it back to customer satisfaction.
Bonus: Define the expected impact of the tool and report back on it's success or failure.
3. Do you have the resources and know-how to properly execute and use this tool to its fullest?
If not, should you hire additional resources, or should you shelve this tool until you have more time.
4. Are they priced fairly for the value they provide? Are they priced on a value metric? Are you paying for features that you already have / don't need?
If you're paying for two tools that do the same thing, there's a cost waste, and typically some convolution between the tools. Figure out if this tool covers exactly what you need. While you want to prepare for growth and enacting "cool" features in the future, it's important to be able to compartmentalize what you need today from what you need tomorrow.
5. How do the features differentiate from competitors?
If it's unclear, I'd typically go with a market leader, best funded, or best reviewed.
6. Does this tool fit with the rest of your tool stack?
It's more important than ever that all of your tools talk to each other. Make sure it integrates with your core apps appropriately. Make sure the sales rep isn't saying "yes," but really means that you have to use a webhook or Zapier (both are workarounds when you don't have a direct integration, which is always prefered).
