This case study is based on outcomes reported by early-access wholesalers in the Caribbean apparel trade. Names and figures are representative of real workflows; details are composite for privacy.
The problem: Excel could not keep up with size-color grids
Island Thread & Textile Ltd. imports men's and women's apparel for 40+ retail accounts across Trinidad, Tobago, and the Eastern Caribbean. Each style ships in 4–6 colors and sizes S through XXL — roughly 1,200 active SKUs when variants are counted separately.
Stock lived in a shared Excel workbook. POS at the counter used a different export. Catalogs were rebuilt in Canva every season. The result was predictable:
- Popular sizes sold out while the spreadsheet still showed stock
- Buyers waited 24–48 hours for updated price lists
- USD invoices and TTD walk-in sales used different exchange rates
- Monthly counts took a full weekend
"We knew our problem wasn't lack of demand — it was not knowing which size-color cell was actually on the shelf."
What changed with matrix inventory POS
The team migrated to Katalogo over two weeks — importing styles, building color-size matrices, and training three counter staff. Key workflow shifts:
- Matrix picker at POS — cashiers tap the color row, then the size cell; out-of-stock cells are visible before the sale
- Dual currency at checkout — wholesale accounts in USD, walk-in retail in TTD, with the exchange rate snapshotted on every ticket
- Live PDF catalogs — seasonal lines exported from the same SKU list buyers see at POS
- B2B credit ledger — trade accounts with aging instead of a separate receivables notebook
Results after 90 days (representative)
| Metric | Before | After |
|---|---|---|
| Size-color stockouts (monthly) | ~35 incidents | ~21 (−40%) |
| Time to send buyer catalog | 1–2 days | Under 1 hour |
| Month-end count duration | 2 days | 6 hours |
Why matrix beats flat SKU lists for apparel
Flat SKU spreadsheets hide the grid. A buyer asks for "navy, size L" and your rep scrolls 200 rows. Matrix inventory surfaces the two-axis view your warehouse actually thinks in — the same model described in our size-color matrix guide.
Caribbean wholesalers also deal in USD list prices with TTD settlement. Dual-currency POS records the rate on each sale so month-end reconciliation matches what the buyer paid — not a stale spreadsheet conversion.
Lessons for similar operations
- Import styles first, variants second — one parent product per style keeps the matrix manageable
- Train counter staff on the matrix picker before opening B2B credit to trade accounts
- Send catalogs from live stock so buyers never order off a PDF from last season
