One narrow piece of software, billed monthly
A small tool that fixes one annoyance inside a niche you already know from the inside, sold on a monthly subscription. The hardest and slowest start in the catalog: months of building before anything is billable, and cancellations end more of these than launches do.
$0-300
$1,000-5,000/mo recurring
Top of range — not a guarantee
Picking the problem is the skill — the code is the part that can be learned.
Software costs almost nothing to copy, so the second customer is nearly free while the first one carries nearly all the work — that asymmetry is the whole argument for the shape, and the months it takes to reach it are the price. Subscriptions cut both ways: the same billing that stacks month over month also leaks, so keeping the accounts already signed up decides more than adding new ones.
