Common Mistakes to Avoid

Even the best hubbuycn spreadsheet fails if you fill it with bad habits. This guide exposes the five most expensive mistakes resellers make, shows how to spot them early, and gives you a clean recovery plan for each one.

Mistake 1: Skipping Shipping in Total Cost

The single most damaging error is treating product cost as total cost. International shipping, warehouse fees, and customs can add 25-40% to your landed price. If your margin formula only uses unit cost, every pricing decision is wrong.

Fix: Always include a Domestic Shipping and International Shipping column. Split per-item shipping by weight or quantity, then add it to your Total Cost formula.

Mistake 2: Inconsistent Category Naming

Typing 'Shoe', 'shoes', 'Sneakers', and 'Footwear' in the same Category column breaks your filter views and dashboard summaries. One typo and a whole category disappears from your monthly report.

Fix: Use Data Validation dropdowns for Category and Status. Lock the list to exact spellings and never type free text into those cells.

Mistake 3: Editing Formula Cells Directly

Beginners often see a wrong number in the Margin column and type a correction directly into the formula cell. That breaks the entire column for every future row and creates silent errors that are hard to trace.

Fix: If a formula result looks wrong, check the input cells. Never overwrite a formula. If you must override one row, add a Manual Override column and reference it conditionally.

Mistake 4: Forgetting to Archive Sold Items

An active sheet with three hundred sold rows becomes slow, cluttered, and hard to scan. Worse, old sold data pollutes your status filters and makes it look like you have more pending orders than you actually do.

Fix: Move every row with Status = Sold to a separate Archive tab weekly. Keep only Ordered, Shipped, Arrived, and Listed in your active view.

Mistake 5: Mixing Currencies Without Conversion

Paying a supplier in Chinese Yuan, shipping in USD, and selling in GBP creates a three-currency nightmare. If you enter all three into one column without conversion, your Total Cost and Margin formulas become meaningless.

Fix: Pick one base currency for your sheet. Convert all costs before entry, or add a Currency and Exchange Rate column so your Total Cost formula multiplies foreign amounts correctly.
