Inventory / COGS — June
Wholesale and materials orders with supplier invoices, noted by SKU.
Ecommerce finance · Seller expenses
Organize every ecommerce cost by category and month
Selling products online means a long tail of costs no two of which look alike: a wholesale inventory order, a roll of poly mailers, the marketplace's listing fees, an ad spend on a new product, packaging inserts, and the cost of a return. Without one categorized record, you can't see where the money actually goes. A template that records each cost by category with a per-SKU or per-order note keeps it all sortable. Cash Workspace gives online sellers one place to record costs, attach receipts, and file by month and fiscal year — no marketplace or ad-account integration.
The problem
Why ecommerce expenses are hard to pin down
Costs come from many sources at different cadences, and platform fees and ad spend hide inside dashboards you rarely reconcile into your records.
- Inventory orders, shipping supplies, and ad spend all hit different accounts.
- Marketplace and payment-processing fees are buried in payout reports.
- A return costs you the refund plus return shipping, but never gets logged.
- Packaging — boxes, mailers, tissue, inserts — is bought in bursts and forgotten.
- At year-end you can't tell COGS from overhead because nothing was categorized.
The workflow
Categorize, note the SKU, file by period
Record each cost against one category with an order or SKU note, attach the receipt, then file monthly and yearly.
- 1
Set your categories
Agree on a list: inventory/COGS, shipping supplies, platform fees, ads, packaging, and returns.
- 2
Record each cost
Capture category, vendor, amount, and date, plus a per-SKU or per-order note where it applies.
- 3
Attach the receipt
Add the supplier invoice, supply receipt, or fee statement to the record.
- 4
Log fees and returns
Read platform and processing fees from payout reports and record them; log each return's refund and return shipping.
- 5
File monthly and yearly
Keep a monthly folder and roll it into a fiscal-year folder so categories total cleanly at year-end.
Record structure
What to record for each ecommerce expense
A consistent field set keeps COGS, overhead, and ad spend separable.
- Category
- Inventory/COGS, shipping supplies, platform fees, ads, packaging, or returns.
- Vendor / source
- Supplier, supply store, marketplace, or ad platform.
- Amount
- The total and currency for the line.
- Date
- When it was paid, so it lands in the right month.
- SKU / order note
- The product or order the cost relates to, where applicable.
- Return detail
- For returns, the refund amount plus return shipping.
- Fee source
- For platform or processing fees, the payout report the figure came from.
- Receipt
- The attached supplier invoice, supply receipt, or fee statement.

Common mistakes
Mistakes to avoid
- Mixing inventory/COGS with overhead so neither totals cleanly.
- Ignoring platform and processing fees because they're inside payout reports.
- Forgetting return costs — the refund and the return shipping.
- Recording packaging buys without a category, so they vanish into 'misc'.
- Skipping the SKU or order note, so a cost can't be traced to a product.

FAQ
Ecommerce expense tracker FAQ
- Does this pull fees from my marketplace or ad accounts?
- No — there's no marketplace or ad-account integration. You read fees and ad spend from your payout and ad reports and record them yourself, so the records stay complete and under your control.
- How should I handle returns?
- Record each return as a 'returns' line capturing both the refund and the return shipping, noted by order, so the true cost of a return shows up rather than disappearing.
- Can this separate COGS from overhead for me?
- You separate them by recording each cost under the right category — inventory/COGS versus shipping, fees, or ads. Cash Workspace organizes the records; it does not compute profit or margin.
