Eastmallbuy Spreadsheet for Resellers: Inventory and Margin Tracking (2026)
Reselling through buying agents requires a different level of organization than personal shopping. You need inventory tracking, margin calculations, platform comparisons, and customer order matching. This reseller-focused eastmallbuy spreadsheet guide covers the exact columns, formulas, and workflows that successful resellers use to manage bulk orders, avoid dead stock, and maximize profit on every item.
Just getting started with spreadsheets? Learn the basics first.
Beginner GuideEssential Reseller Columns
Personal buyer spreadsheets track purchases. Reseller spreadsheets track investments. Add these columns to your eastmallbuy spreadsheet immediately: Resale Platform, List Price, Estimated Fees, Net Profit, Profit Margin Percentage, Days to Sell, and Customer Order ID.
The List Price column records what you intend to charge. Estimated Fees includes platform commissions, payment processing, and shipping to your customer. Net Profit calculates List Price minus Total Cost minus Estimated Fees. Profit Margin Percentage divides Net Profit by Total Cost so you can instantly see which items earn the highest return on investment.
Inventory Status Workflow
Resellers need more granular status tracking than personal buyers. Expand your Status column with these values: Ordered, In Transit to Warehouse, Inspecting, Photographing, Listed, Reserved, Sold, Shipped to Customer, and Return Pending. Each status change represents a real business action that affects your cash flow.
Color code aggressively. Green for "Sold" because it means money is incoming. Yellow for "Listed" because the item is exposed but not yet earning. Red for "Return Pending" because it threatens your margin. A properly configured eastmallbuy spreadsheet guide makes your entire inventory health visible at a glance.
Bulk Order Management
When ordering fifty items in one haul, tracking becomes complex. Create a "Haul" column that groups items by purchase batch. Assign each haul a code like H-2026-05-A. This lets you filter and analyze batch profitability, shipping cost per item, and overall haul margins.
Use a separate "Haul Summary" tab that pulls data from your main sheet using SUMIF formulas. Each row in the summary tab represents one haul, showing total items, total cost, total shipping, average cost per item, and number of items already sold. This high-level view prevents losing money on bulk purchases that seemed cheap individually.
Platform Comparison Tracking
Not all resale platforms are equal. Create a Platform Performance tab that tracks which marketplace generates the best margins, fastest sales, and lowest fees. Record the platform name, total items listed, items sold, average days to sell, total fees, and net profit per platform.
After three months of data, patterns emerge. You might discover that Platform A moves streetwear fastest while Platform B rewards vintage items with higher margins. These insights let you route inventory strategically rather than listing everything everywhere blindly.
Frequently Asked Questions
What minimum margin should I target?
Most experienced resellers aim for forty percent minimum margin after all fees and shipping. Lower margins are acceptable for fast-moving items that sell within seven days.
Should I track unsold inventory value?
Yes. Create a running total of inventory value so you understand how much capital is tied up in unsold stock. This prevents over-purchasing and cash flow problems.
How do I handle returns in the spreadsheet?
Add a "Return Loss" column that records the negative impact. Subtract this from your monthly profit summary. Track return rates by seller to identify unreliable suppliers.
Can one spreadsheet handle both buying and selling?
Yes. Use separate tabs: Procurement for agent orders, Inventory for received items, and Sales for customer transactions. Link them through SKU or order number references.
