How Sqquid works

Sqquid connects the systems that run your retail operation. These pages explain the rules that apply across Shopify, marketplaces, POS systems, and other services.

Use these pages when you want to understand why Sqquid behaves a certain way. For instructions that apply to one provider, use its Connection guide.

For day-to-day tasks, use Daily Operations. Start with the Dashboard to review activity, or open the guides for Products, Orders, and Fulfillment.
