I don't handle the fulfilment myself. I wrote a software integration that connects NewBusinessMonitor with a direct mail company in the UK. They have special machines that can print, envelope, and send all the letters automatically, at large scale. The letters are printed in colour (on rather nice quality paper), trimmed by guillotine (for full-bleed printing), folded in half and inserted into a windowed envelope, before being dispatched 2nd class, usually the following business day.
I typically don't need to manually intervene in any part of the process; I just try and do hand-holding with people when I onboard them, because I think good business is about building relationships with people, and many (most?) of my users specialise in areas outside of computing.
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.
