Sage 300 and Square POS Integration
- Simple
- Fast
- Secure
Sage 300 and Square POS integration helps your front counter and back office see the same figures. Product information, customer details and sales from the till match what finance and operations see in Sage 300.
With APPSeCONNECT, Sage 300 continues to manage items, stock levels, pricing and accounting. Square POS keeps handling in-store sales, receipts and basic customer details. The connector facilitates bi-directional data exchange, ensuring that a terminal sale or a Sage 300 update is instantly reflected across both systems, preventing data silos. This Sage 300 & Square POS integration keeps both systems working from the same, up-to-date sales and stock data.
Key Benefits
Why APPSeCONNECT Is the Gold Standard for Sage 300 & Square POS Automation
Running Square POS and Sage 300 separately often means extra steps. Sales totals from the day are keyed into Sage 300 by hand. Stock counts in the ERP and store inventory gradually desynchronize, leading to discrepancies. End-of-month close requires excessive time due to reconciliation errors and mismatched figures. APPSeCONNECT reduces these small gaps and helps teams rely on one view of sales, stock and customers.
Unified Transaction View
Store sales recorded in Square POS relate directly to entries and documents maintained in Sage 300.
Cleaner Daily Close
Sales, tax and tender details reach Sage 300 promptly, so reconciliations do not pile up at month-end.
Reduced Manual Entry
Staff spend less time copying numbers from POS reports into the ERP.
More Accurate Stock
Quantities in Sage 300 reflect what has already been sold on the shop floor.
Better Customer Context
Basic customer and contact details are easier to match across counter activity and back-office records.
Fewer Adjustment Runs
Fewer mismatches mean fewer correcting entries and manual fixes after business hours.
Scales With Growth
As the number of stores or devices increases, automation carries more of the day-to-day workload.
B2B AUTOMATION
Where Sage 300 Meets Square POS Automation
Square POS focuses on capturing sales quickly at the counter. Sage 300 focuses on stock, pricing, purchasing and financial control. The integration lets each system keep that focus while sharing information that both sides need.
APPSeCONNECT manages how records move between Sage 300 and Square POS, so updates follow predictable rules rather than one-off imports.
- Products From ERP: Item information maintained in Sage 300 forms the base for what appears on POS screens.
- Customer Records Linked: Customer details captured at the point of sale connect to accounts that finance and sales teams recognise.
- Sales Into ERP: Completed sales from the terminal become records Sage 300 can post, report on and analyse.
- Stock Positions Updated: Movement recorded by the POS reduces on-hand amounts tracked in Sage 300, helping planning and replenishment.
- Straightforward Oversight: Administrators review mappings and schedules from a single integration console instead of juggling several tools.
