Seller recordkeeping checklist
A simple checklist for tracking costs, fees, shipping, refunds, and inventory decisions for cleaner seller math.
What to track
Good records make every calculator more accurate. Track the cost of goods, shipping paid, shipping charged, platform fees, payment fees, packaging, refunds, discounts, and inventory dates. The goal is not complicated accounting. The goal is to know whether selling activity is actually profitable.
- Item cost and purchase date
- Platform and payment fees
- Shipping labels and supplies
- Refunds, returns, and resale losses
How often to update
Small sellers can update weekly. Higher-volume sellers should update daily or automatically through exports. Waiting too long makes it harder to connect a fee, refund, or discount to the correct order.
- Weekly for low volume
- Daily for high volume
- Monthly review for stale inventory
Use records for decisions
Records should change behavior. If one category has high returns, price it differently. If one platform has higher fees but faster sell-through, compare profit and cash flow together.
Quality note
This article is written to support better seller decisions, not to promise earnings or replace official rules. Use it with RotoCurve calculators, verify current rates with the source that controls them, and keep records when a decision affects tax, marketplace compliance, or shipping cost.
For AdSense readiness, RotoCurve content should answer a real user question, explain the assumptions behind the math, and point readers toward practical next steps. Pages should not exist only to hold ads or repeat the same wording with a different title.
When a topic affects money, tax, shipping, or marketplace compliance, treat this page as a starting point. Save your inputs, check official sources, and update the calculation when fees or policies change.
