How to Start a Substack Writer Business

Bottom Line

Starting a Substack Writer business takes $500-5,000 in startup costs, proper licensing for your state, and business tools (invoicing, scheduling, CRM, bookkeeping). The median Substack Writer earns $32,000/year. Most new substack writers make the mistake of renting $100-200/month in software subscriptions from day one — that is $1,200-2,400/year before you have a single client. Nexa is $279 once for all of it. Biz Wiz ($19.99) builds you a personalized plan with your state's exact licensing requirements, pricing research for your area, and a 90-day action checklist.

Writing is the visible half; the business is the rest. Morning starts in the draft, the actual work, fitting deep writing into the hours before the world wakes up, with a paywall decision looming, how much of this post is free to pull readers in versus paid to reward subscribers. Then the dashboard, where overnight there were four new paid subscribers and, less welcome, two annual subs that lapsed without renewing, which is the quiet churn that annual billing hides until it's already gone. The writer checks which post or Note drove the new signups, because knowing what converts is the difference between guessing and growing. Midday is engagement: replying to comments and DMs from paying subscribers who expect access, plus a cross-promotion swap with another writer in the recommendations network. Afternoon is planning, sketching the next two weeks of posts to balance free reach against paid value, and answering a reader who's on the fence about upgrading. There's also the unloved bookkeeping: Substack's payout already netted out its cut and Stripe's fees, so the deposit doesn't match the gross subscription revenue, and for taxes both numbers matter. A brand reached out about a sponsored post, which means a rate decision and a note to keep it clearly disclosed. The day ends scheduling the next paid post, noting which lapsed subscribers might win back, and logging the month's gross and net so April isn't a guess.
