Ask HN: How do you ensure that your customers are profitable?
The problem with my business model is that I can't be profitable unless my customers are profitable (and rightfully so). A lot of times I feel that I can offer some help (e.g. by reminding them that selling something people want is more important than a perfect web design or that building an opt-in email list is usually more important than building Twitter followers), but we are a platform provider, not an advisor/consultant. A landlord can only do so much to ensure that his tenants are making money and thus able to pay rent every month.
I think it was Paul Graham that said that startups shouldn't sell to startups and, if they do, bad things happen. My question is how do companies like Shopify, Volusion, and other ecommerce platforms out there tackle this problem? How do they make sure that their customers do well -- apart from improving their platform, which they have already been doing all the time?
