HN crowd looks down on sales reps. But a good sales rep will 1) understand your business 2) will look for ways to match your needs to solutions they offer 3) will be your point of contact when things go wrong.
Sales reps are human beings, treat them well, thank them for their time if you don't buy the fancy/expensive enterprise plan.They'll understand. Most reps are young college grads that are building a network for life.
You could be a solo SaaS creator and cheap because it is a side gig and your don't have the money. But still make an effort to nurture those little young reps. One day they'll make the phone call to somebody that will remove that account suspension. That will save your business.
