What’s the best piece of advice when dealing with any type of customer on my deal page (positive or negative)?

Roadmap

• Give potential users a quick background on the history of the product, what's to come, or any specific details you want to share. 
• Feedbear has offered to give AppSumo Partners access to a free roadmap! Check it out here!

Customer support 

• Be sure to set realistic support expectations! 
• We find it successful when partners under promise and over deliver features.

Quick response times 

• Getting a timely response from a partner has the potential to resolve friction points for a customer, increasing ARR. 
• Which in turn increases your product's trustworthiness on our marketplace.

Things to avoid

• Taking too long to approve or respond
• Not answering customers’ questions completely
• Inability to address all feedback positively
• Arguing with the Sumo-lings
