What you can do with it
Multi-channel sales ledger
One row per order line: quantity, price, shipping charged, discount, refund and fee credit, for every channel.
Fee rules you control
Commission %, fixed fee per order, listing fee and payment processing, with an effective-from date so a fee change applies only from that day.
Monthly P&L
Net sales, fees, product costs, shipping, ads, other costs, net profit and margin for 12 months.
Profit per product & channel
Units, fees, costs, profit, margin and profit per unit; top 10 products and a table per channel.
Tax set-aside
Put aside the % of profit you choose, per month and for the period (your %, not tax advice).
Data checks
Unknown channels or products, sales with no fee rule for their date, missing costs, duplicates, percentages above 100%.

Why buy it instead of building it
Checked against an independent calculation
Before release, every formula is compared with a separate model, including edited data and deliberately bad entries.

- Not accounting or tax software; the tax set-aside is a percentage you choose, not tax advice. Sales tax/VAT is not tracked.
- No connection to any marketplace: you enter or paste sales lines. One currency per file; 5,000 sales lines, 300 products, 12 channels.

Questions
Does it include Etsy or other platform fees?
No. Fees change, so SellerBook ships none: you enter each channel's current fees from its own fee pages and add a new dated row when they change.
What happens when a platform changes its fees?
Add a new fee rule with the date it starts. Sales before that date keep the old fees; sales from that date use the new ones.
How do I record a refund?
Enter the refund on the order line, or on its own line later with the same order ID and no quantity. Enter any fees the platform gave back as a fee credit.
Is the tax set-aside my tax bill?
No. It is the percentage of profit you choose to put aside. SellerBook does not calculate tax and gives no tax advice.
What if it doesn't work for me?
Email altaitoondev@gmail.com within 30 days of purchase. We'll try to fix the problem first; if we can't, you get a full refund through the store you bought from.
