Common questions

Can I use RELEX Fashion AI or ToolsGroup SO99+ on my phone?

No, neither tool has a mobile app. They are desktop-only enterprise platforms designed for supply chain planners working on large screens.

Which tool is easier to set up for a small business?

Neither is easy or affordable for small businesses. Both require months of setup, clean data, and a team of specialists. If you're a small retailer, look at simpler tools like TradeGecko or Cin7 instead.

How much do these tools cost?

Do these tools work with my existing software?

Both integrate with ERP systems like SAP and Oracle, but neither has a public API or direct integrations with common small-business tools like Shopify or QuickBooks.

RELEX Fashion AI wins for fashion-specific planning, ToolsGroup SO99+ for general supply chain, but neither is for everyday users.

If you're a large fashion retailer with a data team and budget, RELEX Fashion AI is the better pick for your specific needs. For a general supply chain overhaul across industries, ToolsGroup SO99+ is a solid choice. But if you're an everyday user or small business owner, skip both—they're not built for you.
