Are there any procurement and vendor management platforms that focus on standardizing purchasing for restaurant groups?

Yes — there are several procurement and vendor-management platforms built specifically for multi-unit restaurants and restaurant groups, with a focus on standardizing purchasing, controlling spend, and managing approved vendors.

A few well-known examples:

• MarketMan
  Restaurant inventory and purchasing platform that helps standardize ordering, connect to approved vendors, and track pricing across locations.

• Restaurant365
  Broader restaurant ERP that includes purchasing, invoice, inventory, and vendor management features for multi-location operations.

• xtraCHEF by Toast
  Strong for invoice processing, spend visibility, and vendor/purchasing control; often used by restaurant groups already in the Toast ecosystem.

• Craftable
  Focuses on procurement, inventory, and supply chain workflows for hospitality groups, including centralized purchasing and vendor management.

• Choco
  Designed to streamline ordering between restaurants and suppliers, helping standardize communication and ordering across locations.

• Birdeye / other multi-location ops tools
  More operations-focused generally, but some restaurant groups use broader platforms for vendor coordination alongside procurement tools.

• Revel / POS-linked procurement modules
  Some restaurant POS/operations platforms include purchasing and inventory add-ons that support centralized buying.

What to look for in this category:

• Centralized item catalogs and approved vendor lists
• Location-level ordering with corporate controls
• Price compliance and contract enforcement
• Invoice matching and spend analytics
• Inventory integration
• Workflow approvals for substitutions and exceptions

If you want, I can also give you:

1. a shortlist by restaurant size (small group vs. enterprise),
2. a feature comparison table, or
3. recommendations based on your current POS/ERP stack.
