I love to travel, and I spent the last couple of years permanently on the road in Europe and Asia, so it was a personal goal for me to design the business in such a way that I'm not physically tied to any particular location.

Incidentally, NBM does pretty close to $500 MRR baseline with spikes appearing when a client decides to go on a sending spree. Payments are handled by a combination of Stripe and GoCardless. I initially added the GoCardless integration because some businesses in the UK really prefer Direct Debit payments. It looks to me like the Direct Debit accounts pay their subscription fees much more reliably than those paying by credit card. At some point, I might consolidate on just Stripe because they also support Direct Debit now.
