Reselling and inventory management spreadsheets are structured Excel or Google Sheets files that turn your sourcing, listing, and selling data into usable numbers: stock on hand, cost of goods, marketplace fees, and profit per item. You can start with free templates from major platforms or niche creators, then adapt or buy more specialized tools once your SKU count and complexity grow.
For most US-based resellers with a few hundred SKUs, a good spreadsheet is effectively your operations platform. It tells you what to reorder, which suppliers are worth keeping, and which products are actually profitable after shipping and fees. As your business scales past roughly 1,000 SKUs or multi-channel sales, you’ll feel where basic sheets fall short and where a paid template or software—and even printed tools—might make more sense.
How Reselling Inventory Spreadsheets Work in a Real Business
A reseller inventory spreadsheet usually mirrors your workflow: sourcing, listing, selling, and analyzing. A practical setup often has three core tabs:
- Inventory master – every SKU and its current status.
- Sourcing / purchase log – where you bought it, for how much, and when.
- Sales & fees – each sale with platform fees, shipping cost, and profit.
Typical columns and why they matter
On the inventory master, you’ll typically track:
- Item ID / SKU
- Product title
- Category (e.g., sneakers, electronics accessories)
- Supplier name
- Purchase date
- Quantity on hand
- Location (bin/shelf)
On the sourcing tab, you add cost detail:
- Purchase price per unit
- Estimated shipping/import cost per unit
- Landed cost formula: `purchase price + per-unit shipping/import`
Microsoft offers free inventory list templates in Excel that already include product and stock columns and built-in formulas for counts and totals. You can adapt those templates for reselling by adding landed cost and supplier fields; see the Microsoft inventory templates.
On the sales & fees tab, useful columns include:
- Marketplace (eBay, Amazon, Mercari, your own site)
- Sale date
- Sale price
- Platform fees (final value fees, payment processing)
- Shipping cost
- Profit per item formula: `sale price – platform fees – shipping – landed cost`
Templates like the free reseller inventory sheet from Sheetrix and the Google Sheets templates from SpreadsheetPoint are already geared toward tracking sales, COGS (cost of goods sold), and profit. You can use them as a starting point rather than building every column and formula yourself.
How this connects to your sourcing decisions
If you source cross-border (say, pallets of liquidation goods plus small cartons from overseas suppliers), your spreadsheet is what keeps those streams coherent. Each purchase line ties to:
- Supplier and country
- Currency converted to USD
- Freight and import fees spread across units
That data lets you compare, for example, a domestic supplier at $4 landed cost vs a cross-border supplier at $3 landed cost but longer lead times. Over a year, your sales & fees tab shows which sources consistently deliver items that sell quickly and profitably, and which create dead stock. A well-structured spreadsheet becomes your evidence for negotiating prices or dropping a supplier.
Choosing and Vetting Spreadsheet Templates and Sellers
You can get reseller spreadsheets from three broad places: generic inventory templates on big software platforms, niche reselling templates on specialist sites, and paid downloads from creator marketplaces.
Free and low-friction options
- Microsoft Excel templates – The inventory list templates mentioned above are easy if you already live in Excel and want built-in formulas and a familiar interface.
- Google Sheets reseller templates – Sheetrix offers a free Google Sheets reseller inventory template tailored to reselling workflows, and SpreadsheetPoint publishes templates designed specifically to track sales, COGS, and profit in Sheets.
These are good for:
- 100-500 SKUs
- One or two sales channels
- Owners comfortable tweaking formulas but not ready to build from scratch
Paid templates from marketplaces (example: Etsy)
On marketplaces like Etsy’s reseller spreadsheet category, you’ll find paid templates marketed to eBay, Poshmark, or multi-platform sellers. Listings often highlight things like:
- Maximum inventory size (some advertise 30,000+ items)
- Pre-built dashboards (monthly profit charts, sales by platform)
- Platform-specific columns (Poshmark shares, eBay item IDs, etc.)
Treat these template creators like suppliers:
- Check structure, not just aesthetics. Scan listing screenshots. Do you see explicit COGS, fees, and profit formulas? Are columns labeled clearly for your marketplaces?
- Match capacity to your roadmap. If you expect to grow from 500 to 5,000 SKUs, a template advertised for “30,000 items” may be worth the learning curve.
- Look for support signals. Review how buyers describe using the sheet—are they resellers like you, and do they mention timely help when formulas break?
Apply sourcing-style vetting to template sellers
Think of template selection like choosing a small wholesale supplier:
- Niche fit: Does the seller specialize in reselling tools, or is the spreadsheet one of many generic downloads?
- Update behavior: Are there version numbers or notes about updates for new marketplace fee structures?
- Licensing clarity: Is usage clearly defined (single user vs multi-seat)? Ambiguous terms can create friction as you hire help.
Reddit’s `/r/reselling` and similar communities—such as threads asking for “inventory spreadsheet” recommendations—can be useful informal references to see which templates and structures resellers actually use, but treat them as anecdotal rather than formal reviews.
When to Upgrade: From Free Sheets to Paid Templates or Software
Spreadsheets scale surprisingly far, but they do have limits. Think about your own business in three rough tiers.
Tier 1: Early-stage resellers (under ~200 SKUs)
Free templates are almost always enough here. Your focus is:
- Learning basic COGS and profit tracking
- Building the habit of weekly updates
- Keeping clean records that support tax filing and financial decisions
General business expense spreadsheet guidance—like the steps laid out in DHgate’s editorial content on building an expense sheet—emphasizes regular updates and customized categories so owners can stay organized and make better decisions. That same mindset works for your inventory and sales spreadsheets, though you should still consult a professional for tax and compliance questions.
Tier 2: Growing operations (200-1,000 SKUs, multi-channel)
Pain points usually appear as:
- Too many manual steps (copying sales from multiple marketplaces)
- Frequent formula errors when adding new channels or fees
- No quick view of profit by supplier or category
At this stage, upgrading options include:
- More advanced paid templates with dashboards and automation (for example, multi-channel reseller sheets from marketplace sellers).
- Dedicated inventory/accounting software once you want live integrations to marketplaces.
- Printed tools like budget binders or income-and-expense notebooks if you or staff prefer some offline tracking.
For physical tools, marketplaces can be another sourcing route. For example, as of 2026-09-28, DHgate listings include products such as:
- Budget Binder Sheets – 60Pcs Expense Budget Organizer – a set of budget binder sheets positioned for expense and finance management.
- Daily Income and Expense Notebook for Budget Planning with Weekly Tracker – a notebook designed for logging daily income and expenses.
Prices and availability can change, and these listings don’t replace digital systems. But if you want physical budget binders or notebooks to complement your spreadsheet workflow—for staff on the warehouse floor or for quick daily tallies—they’re an option. As with any marketplace supplier, you’d verify the listing details, check seller history and feedback, and consider a small initial order before standardizing on a specific product.
Tier 3: High-volume and complex sourcing (1,000+ SKUs, many suppliers)
Once you’re managing thousands of SKUs, spreadsheets often hit their practical ceiling:
- File size and speed issues
- Harder collaboration with multiple staff editing
- Risk of inconsistent versions across devices
At this point, consider:
- Inventory or accounting software with role-based access and automatic imports.
- Using spreadsheets mainly as analysis tools (profit by supplier, category performance) fed by exports from software.
Quick view: free vs paid spreadsheets, software, and printed tools
| Tool type | Rough SKU fit | Typical strengths | Typical limitations |
|---|---|---|---|
| Free generic inventory templates (Excel) | ~50-300 | Easy start, familiar UI, basic stock & totals built in | Limited resale-specific fields; more manual setup |
| Free reseller sheets (Sheetrix, SpreadsheetPoint) | ~100-500 | Reseller-focused columns for COGS & profit; Google Sheets access | May need tweaks for cross-border landed cost |
| Paid reseller templates (creator marketplaces) | ~200-5,000+ | Larger item capacity, dashboards, platform-specific layouts | One-time creator support; quality varies by seller |
| Inventory/accounting software | ~500-10,000+ | Integrations, user permissions, export/import options | Subscription cost; migration from spreadsheets needed |
| Printed tools (binders, expense notebooks) | Any size, but best as a complement | Good for quick notes, staff who prefer paper, warehouse tally sheets | Not searchable like spreadsheets; harder to aggregate data |
Use this table as a rough guide, not a rulebook. If you’re running a lean cross-border operation, you may prefer sticking with spreadsheets longer and investing more time in customization, as long as you can still audit and back up your data.
Whatever route you choose, keep the core practices consistent: record every purchase and sale, separate personal and business finances, and maintain detailed inventory records. Spreadsheets—free or paid—are simply the tool you use to make those habits reliable.
