For US-based solo Gumroad & Stripe sellers
Stop dreading tax season as a digital seller.
A local CLI that auto-imports your Gumroad and Stripe CSV exports, calculates real profit after fees, and estimates your quarterly tax set-aside. No spreadsheet formulas to maintain.
One-time payment. Instant zip download after Stripe checkout — same delivery shape as Gumroad's instant file. See what's included ↓
The problem it solves
You built a product. Sales are coming in. Then tax season arrives and you're staring at a pile of payout emails, platform exports, and CSV files — with no idea what your actual profit was or what you owe.
Every sale & fee, organized
Pre-built income and expense categories made for digital sellers: platform fees, processing fees, ad spend, software, contractors, refunds.
Auto-import your CSV
Point the CLI at your Gumroad and Stripe exports. It categorizes and logs every transaction for you.
Real profit, not just gross
P&L summary calculated automatically. See true margins after fees — the number that actually matters.
Quarterly set-aside estimate
Pass a tax rate → an estimated amount to put aside. So April is never a surprise.
Up and running in three steps
Clone of Orion's Gumroad one-page setup guide (PDF) — same three-step promise on SellerLedger ($17), adapted for CLI + instant zip delivery.
Step 1 — Get the CLI
After EUR 9 Stripe checkout you are redirected to seller-ledger-cli-v1.0.0.zip. Unzip — seller_ledger.py is inside. Or try free with the sample CSVs below.
Step 2 — Export your CSVs
Gumroad: Settings → Payouts → Export. Stripe: Payments → Export. Save both files locally — the CLI never uploads them.
Step 3 — Run one command
python3 seller_ledger.py gumroad.csv stripe.csv -o ledger.csv --tax-rate 0.28 — prints gross, fees, net profit, and quarterly set-aside. Open ledger.csv in Sheets for the tab view.
Need client documents too?
Orion cross-sells his Freelancer Kit on Gumroad. Our clone: the invoice batch pack + solo-business stack bundle — win clients, track every dollar.

Who it's for
