Every Gumroad and Stripe export uses different column names. Without a mapping layer you end up hand-labeling rows: is this a fee or revenue? Was this a refund or a negative sale?
SellerLedger on Gumroad ($17) ships pre-built category mapping inside the Transactions Log and Apps Script Auto-Importer — Gumroad and Stripe CSV rows mapped to seller-friendly categories; fee rows split from revenue automatically. Same rules are on their gh-pages landing Transactions tab.
Planning tool only. Not tax advice. Confirm figures with a tax professional.
Orion's mapping rules (what we cloned)
| Source row | Category |
|---|---|
| Gumroad sale | Product Revenue |
| Gumroad fee (10% est.) | Platform Fee |
| Gumroad refund | Refund |
| Stripe payment | Product Revenue |
| Stripe processing fee | Platform Fee |
| Stripe refund | Refund |
| Manual rows in ledger.csv | Ad Spend, Software, Contractors |
Orion's sheet uses Google Apps Script import — Google shows an unverified-app prompt on first run. Our CLI maps categories offline with Python 3 + stdlib only.
Run it locally
python3 seller_ledger.py gumroad-sample.csv stripe-sample.csv -o ledger.csv --tax-rate 0.28
Stdout prints the mapping table then the categorized ledger:
--- Category mapping (Gumroad + Stripe CSV) ---
Gumroad sale row → Product Revenue
Gumroad fee (10% est.) → Platform Fee
...
--- Transactions Log (by category) ---
Product Revenue count= 2 net= 131.00
Platform Fee count= 2 net= -7.08
