Square Inventory

For multi-location & omnichannel retailers: Track online orders, in-store purchases and marketplace sales with item-level stock records and replenishment workflows. Multi-location retailers carry the same catalog across several stores and a website, and small counting errors turn into lost sales or dead stock. Square's inventory tools track stock in real time, print barcode labels and report COGS, sell-through and aging stock. Roots Payments builds the item structure and counting routine so the numbers stay right.
  • Design variants and SKUs so reports roll up correctly
  • Set up vendors, reorder points and purchase orders
  • Label existing stock and run the first full count with you

Square Online (websites)

For multi-location & omnichannel retailers: Give customers an online storefront for online orders, in-store purchases and marketplace sales, with ordering and fulfillment choices suited to your business. Square Online gives multi-location retailers a website with pickup, shipping and local delivery, and Square says in-store sales, online orders and inventory connect automatically. That keeps the same catalog across several stores and a website from overselling across channels. Roots Payments builds the store, product pages and shipping rules.
  • Build product pages with photos, variants and descriptions
  • Set shipping zones, pickup windows and local delivery radius
  • Connect your domain and basic on-page SEO

Square Integrations

For multi-location & omnichannel retailers: Connect Square transaction data with the tools used to manage online orders, store stock and refunds, reducing repeated data entry.

Level 2/3 Processing

For multi-location & omnichannel retailers: Include purchase-order references and itemized invoice data for business-card purchases of online orders, in-store purchases and marketplace sales.
