Paid subs, sponsor slots, affiliate links — one number.
Substack, beehiiv, or Ghost — your income is subscriptions plus sponsorships plus the affiliate links in every issue. Post grounds it all in your bank account and keeps the tax answer current while you write.
Subscription payouts, grounded in the bank
Platform dashboards show gross; your bank shows what you keep after fees. Post books the deposits automatically and lets you log monthly payout detail per platform, so the honest number wins.
Sponsor slots are deals — treat them like it
Classified ads, main-slot sponsors, renewals: Post tracks each from agreement to payment, invoices chased automatically, short payments flagged when the wire doesn't match the rate card.
Affiliate income, reconciled
Post connects to Impact.com, Awin, and CJ natively and imports Amazon reports, then reconciles approved commissions against what actually pays out — the gap is where affiliate money quietly disappears.
Neither exposes a payout API today, so Post works from the source of truth: your bank. Stripe-routed subscription deposits are recognized automatically, and monthly payout logging keeps per-platform detail. Native connections ship as the platforms open APIs.
Connect Impact.com, Awin, or CJ with an API key — or import the Amazon Associates report — and Post tracks approved commissions, then reconciles them against the payouts that land in your bank.
If you expect to owe $1,000+ for the year, generally yes. Post's engine does the math on your real numbers — including your day-job withholding context via your filing status — and tells you what to send each quarter.
