Matrix inventory POS
Size × color inventory built for apparel & fashion wholesalers
Retail POS treats variants as an afterthought. ERP matrix modules need consultants. Katalogo gives wholesalers a visual size-color grid that powers the register, B2B invoices, and PDF catalogs — live in under 30 minutes, included on Free.
What matrix inventory POS should do for your team
Generic POS handles one SKU per product. Spreadsheets collapse at hundreds of variants. Katalogo's 2-D matrix is the foundation every other function reads from.
Visual size × color grid
See Red/S, Red/M, Red/L and Blue/S, Blue/M, Blue/L in one matrix — not 32 separate spreadsheet rows. Scan stock at a glance before a buyer walks in.
Variant-level low-stock alerts
Alerts fire per cell, not per product. Know that Red/M is down to 2 units while Red/L still has 40 — before you promise either to a customer.
Bulk edit across the matrix
Raise prices on every size of a style, swap images for a color run, or mark a whole line discontinued — one action across the entire grid.
POS checkout by variant
Staff pick size and color at the register. Every sale decrements the exact matrix cell — showroom and warehouse quantities stay aligned.
Catalogs from live matrix stock
Generate a PDF line sheet or lookbook from your inventory in 60 seconds. Only in-stock variants appear — no outdated Canva document.
Wholesale credit on variant sales
Invoice on credit by variant. Customer ledgers, aging reports, and payment history tie back to the same matrix — not a WhatsApp thread.
From Excel rows to one live matrix
The workflow apparel wholesalers leave behind — and what replaces it when every sale, catalog, and invoice reads the same grid.
Before
Spreadsheet + Canva + retail POS
- Copy-paste size-color quantities into Excel — one wrong cell, wrong stock for a week.
- Rebuild the line sheet in Canva when prices or colors change (4–8 hours).
- Retail POS sells "the red shirt" but cannot reconcile size M vs L in wholesale credit.
- WhatsApp orders reference variants your spreadsheet forgot to update.
Three tools, zero single source of truth.
With Katalogo
One matrix → POS, invoices, catalogs
- Import your Excel once. Katalogo builds the size × color grid automatically.
- Sell Red/M at the register — that cell decrements; warehouse and showroom stay aligned.
- Generate a PDF catalog from live matrix stock in 60 seconds.
- Invoice on B2B credit by variant; aging reports match what you actually sold.
Import products, first catalog, first sale — under 30 minutes.
Built by a wholesaler. Katalogo's matrix inventory was designed for import-export and apparel operations — not adapted from a coffee-shop POS or an enterprise ERP module.

Who matrix inventory POS is built for
Ideal for small teams — 1–3 staff, 1–2 registers, 200–2,000 SKUs with heavy variant counts.
Apparel & fashion wholesalers
Seasonal collections with 8–12 sizes and multiple colorways. Matrix inventory replaces the Excel tab that crashes at 500 SKUs.
Footwear & accessories distributors
Size runs from 6–13 across styles and colors. One grid per model, variant alerts before reorders, catalogs for retail buyers.
Hybrid showroom + warehouse
Walk-in retail and B2B credit sales from the same matrix. Transfer variants between locations without losing count integrity.
Matrix inventory is the hub — not a standalone module
The same grid feeds PDF catalogs, picture quotations, wholesale price lists, and multi-location stock. Need dual currency at the counter too? Dual currency POS runs on the same SKU list.
