Square POS and Dynamics 365 NAV Integration & Automation
- Automate
- Align
- Accelerate
Square POS and Dynamics 365 NAV integration gives store transactions a controlled path into the ERP. Sales, refunds, payments, customer details, item updates, stock movement, and tax data can move through configured ProcessFlows so store and finance teams are not rebuilding register activity by hand.
Square POS handles checkout, tenders, refunds, and customer activity. Dynamics 365 NAV holds item records, inventory control, posting rules, tax logic, and finance reporting. When the two systems move separately, stock differences grow, payment review slows down, and refund or settlement exceptions become harder to trace.
KEY BENEFITS
Why APPSeCONNECT Is the Gold Standard for Square POS and Dynamics 365 NAV Integration
Our platform provides the integration layer that helps Square POS activity reach Dynamics 365 NAV in a controlled, reviewable way. Store transactions can move with the details finance and operations need, while NAV continues to hold the ERP-side rules for inventory, posting, reporting, and reconciliation. This reduces the spreadsheet work that usually appears between store close and back-office review.
Late Sales Posting
Store sales that stay inside Square after checkout can delay NAV updates. Finance teams then spend extra time entering or checking transaction totals before reports can be trusted.
Tender Reconciliation Gaps
Payment types, authorization references, refunds, and payout timing need the right context in NAV. When tender details move separately, finance teams must compare Square activity against ERP records manually.
Refund Tracking Breaks
POS refunds need to remain tied to the original sale, tax treatment, item record, and customer. A disconnected process makes credit review, restocking, and reporting harder to follow.
Store Stock Drift
Square sales and adjustments change the store view quickly. If NAV inventory is updated later, replenishment, transfer planning, and store availability can be based on different numbers.
Location Reporting Cleanup
Multi-store teams need transaction data by location, register, department, or dimension. Without mapping into NAV, each store can become a separate reporting cleanup exercise.
Tax Posting Risk
Square tax totals, discounts, fees, and refunds need to match NAV tax or VAT rules. Gaps in mapping can slow month-end checks and create avoidable finance review work.
Standard Features Covered in Our Square POS and Dynamics 365 NAV Integration Template
Square POS Sales → Dynamics 365 NAV Transactions
- Completed Square sales can be sent to NAV as sales invoices, sales orders, journal entries, or mapped transaction records based on the posting model. Item lines, quantities, discounts, tax, customer details, and location data can move with the sale.
Square Items → NAV Item Matching
- Square SKUs and item names can be matched with NAV item numbers before records are posted. Variant, modifier, category, and unit details can be included where the POS and NAV item setup support them.
Square Customers → NAV Customer Records
- Customer information captured at checkout can create or update NAV customer records. Contact details, addresses, customer identifiers, and related transaction references can be mapped into the required NAV fields.
Square Tenders → NAV Payment Review
- Card, cash, gift card, and other tender details can move into NAV finance workflows. Authorization references, payment dates, tender types, and store locations can support receipt and reconciliation review.
Square Tax Lines → NAV Tax Groups
- Sales tax collected in Square can be mapped to NAV tax groups, VAT fields, or reporting fields. Refund tax changes and discount-related adjustments can also follow the configured tax logic.
NAV Inventory → Square Stock Counts
- Dynamics 365 NAV inventory can update Square availability for mapped SKUs and locations. This helps the POS work closer to ERP-approved stock levels.
Square Refunds → NAV Credit Handling
- Refunds issued in Square can be routed into NAV as credit memo, return, or review records. The original sale reference, item data, refund reason, tax adjustment, and restock decision can stay connected where the source data supports it.
Square Locations → NAV Dimensions
- Square location data can map to NAV location codes, departments, dimensions, or reporting segments. This helps finance separate store activity without rebuilding reports outside the ERP.
Square Payouts → NAV Reconciliation
- Payout or transfer references from Square can support NAV bank reconciliation workflows. Fees, refunds, timing differences, and settlement references can be reviewed against related POS sales.
Square Adjustments → NAV Inventory Review
- Store-side stock adjustments can be routed into NAV item journal or review flows. This gives inventory teams a way to check shrinkage, corrections, and manual changes before posting.
NAV Products → Square Item Records
- NAV item data can update Square item records when product control belongs in the ERP. SKU, item name, category, status, and price fields can be mapped based on the Square catalog structure.
Register Data → NAV Audit View
- Register, cashier, shift, or device details can support NAV audit and operations reporting when those fields are available. This gives teams more context when checking unusual sales or refund activity.
Discounts and Fees → NAV Posting Rules
- Square discounts, service charges, fees, and adjustments can map into NAV accounts, dimensions, or reporting fields. This helps finance review more than just the final payment amount.
Disputes and Chargebacks → Finance Follow-Up
- Dispute or chargeback references can be routed for review when Square provides the required details. The issue can remain closer to the related sale, payment, and customer record.

INTEGRATION GUIDE
How Does the Workflow Run End-to-End
A Square POS and Dynamics 365 NAV integration is built through ProcessFlows. A ProcessFlow defines the source, target, entity, connector action, schema, mapping, validation, run mode, retry setting, and monitoring route for each movement of data between Square and NAV.
