Integration Overview
Retail and hospitality data often lives in different places POS, back office, and one-off exports. Numbers drift, reconciliation drags on, and reporting lags behind decisions. Teams work hard but still chase inconsistencies.
Square POS captures tickets, tenders, and at-the-counter changes. Microsoft Dynamics 365 Business Central governs inventory, customers, finance, and journals. APPSeCONNECT links both with configurable, low-code pipelines that eliminate retyping and keep every system up to date.
Supported Data Flows / Business Processes
Standard flows ship with validation, mapping, and reliable retry. Use event-driven webhooks for immediacy, or scheduled batches for heavy updates—per flow, per location. APPSeCONNECT Business Central POS Integration centralizes sales, payments, inventory, and customers for finance-ready records.
Scheduling Options
Event-driven webhooks for immediacy, or batch windows for bulk updates—choose per flow.

Integration Architecture
At runtime, an APPSeCONNECT agent (cloud or on-premises) brokers data between Square APIs and the Business Central API surface. Pipelines handle mapping, transformation, validation, and routing. Failed records land in a re-sync queue with full context. A live console provides statuses, metrics, and detailed audit trails. Use our Square POS Business Central connector to trigger webhooks for near real-time updates. Core Components: Orders, Payments, Catalog, Inventory, and Customers endpoints. Sales Orders, Customers, Items, Ledger, Payment Journals. Authentication, mapping, enrichment, validation, and queuing. Security & Compliance: Transport is protected with TLS 1.2; authentication follows OAuth 2.0 where applicable; encryption at rest and auditable access controls are enforced, aligning with ISO 27001 and SOC 2 expectations.
