Need a reason to tell a customer why they need your product?
Tell them what it integrates with.
Tell them what they don’t have to throw out.
No one wants to get rid of what they just spent five figures the year before on. Yes sunk costs are important to consider, but you can ease the blow by highlighting how your product can integrate with many others and not require their investment be thrown out.
Businesses are built around this – Zapier, Flow and yes SLACK – SLACK is succeeding because of it’s level of integrations with other applications.
If you are not integrating with other systems, you are not growing, you are counting down to when you’ll stop.
