Microsoft Dynamics 365 and BigCommerce
Integration Agency & Consultants
Manual order entry and disconnected stock updates start to fail the moment a business moves to Dynamics 365 or scales its BigCommerce storefront. At high volumes, the friction between the governance of an ERP and the agility of a digital storefront leads to reconciliation issues and mismatched tax codes. This usually becomes painful when finance can no longer trust the month-end numbers. We build high-integrity connections that treat Dynamics 365 as the master for product data while ensuring BigCommerce orders post correctly to the general ledger without manual intervention.
Auditing technical gaps and system inefficiencies
We connect Microsoft Dynamics 365 and BigCommerce, supporting your ERP and Ecommerce integration needs. Our consulting services are invaluable, with our system audit uncovering inefficiencies and integration gaps between Microsoft Dynamics 365, BigCommerce, ERP, and Ecommerce platforms. This enables our consultants and your team to take decisive action, ensuring your technology ecosystem runs efficiently. By addressing issues early, you can deliver a reliable customer experience and keep your business operations running smoothly, making the most of your investment in both ERP and Ecommerce solutions.
Solution Design
Integration designs for Microsoft Dynamics 365 and BigCommerce typically prioritise the ERP as the source of truth for product data and pricing. We commonly sequence the order flow first, ensuring BigCommerce transactions map accurately to the Dynamics General Ledger before enabling complex inventory syncs. A key trade-off involves inventory update frequency. Real-time updates help prevent overselling during peak periods but can increase the load on the ERP system. We often recommend a scheduled approach for financial postings to ensure smoother reconciliation at month-end, even if intra-day reporting has a minor lag. This ensures the finance team works from a stable General Ledger while the ecommerce team manages the storefront with high availability.
Mapping data flows and master ownership
The integration functions by treating Dynamics 365 as the master for product, pricing, and inventory data, while BigCommerce serves as the primary engine for customer orders. Data flows are sequenced to ensure that tax codes and shipping methods in BigCommerce map precisely to the corresponding entities in Dynamics. When an order is captured, it is pushed to the ERP to begin fulfilment. Status updates including pick, pack, and ship then flow back to BigCommerce to provide customer transparency. Monitoring is embedded at every stage to detect and surface sync failures before they impact the warehouse or the customer.
Securing data via accredited middleware platforms
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations, Microsoft Dynamics 365 and BigCommerce integration for ERP and Ecommerce is delivered efficiently and securely. IPaaS simplifies connecting Microsoft Dynamics 365 with BigCommerce, automating ERP and Ecommerce data flows, reducing manual effort, and ensuring compliance. The platform’s robust security, scalability, and centralised management provide peace of mind and operational efficiency for businesses integrating BigCommerce and Microsoft Dynamics 365.
Surfacing sync exceptions and reconciliation errors
Standard dashboards often hide operational issues by focusing on volume rather than accuracy. True visibility requires surfacing specific exceptions, such as a BigCommerce order that failed to post to Dynamics 365 due to a missing tax group or a SKU mapping error. These hidden failures often lead to reconciliation issues, where stock discrepancies and financial variances only surface during month-end. Monitoring must track the status of data records, flagging sync failures or data mismatches before they impact the general ledger or lead to overselling.
Handing over operational ownership and manuals
Post-launch adoption focuses on the finance, operations, and ecommerce teams. We hand over a clear operating model that defines data ownership, usually with Dynamics as the master for product data and BigCommerce for order capture. Finance teams learn to check daily reconciliation, while operations monitors fulfilment and inventory syncs. We ensure your team knows how to read alerts from the integration layer so that manual exceptions, like tax mapping errors, are resolved quickly by the correct owner. Documentation is provided as a detailed operational manual for the people running the business. This ensures your team can confidently manage daily tasks and monthly financial closes.
Managing integration health and stock drift
Support focuses on ongoing operational health rather than just basic ticket resolution. We monitor the Dynamics 365 and BigCommerce connection to catch tax mapping failures, stock drift, and sync errors before they impact your financial reporting. By managing the technical health of the integration, we help prevent internal teams from spending excessive time on manual reconciliation. Regular reviews identify potential bottlenecks in the order-to-cash process, ensuring the system remains stable as transaction volumes increase.
Common failures
Mismatched discount and tax application
Operational impact: Sales Orders posted to Dynamics 365 do not match their corresponding BigCommerce checkout totals. This causes persistent reconciliation failures between the BigCommerce payout reports and the Dynamics General Ledger. The finance team is forced to investigate and manually adjust journal entries to balance the books, which undermines trust in revenue and profit reporting.
Prevention / Action: The integration must map every BigCommerce promotion type to a specific charge code or discount account in Dynamics 365 before a Sales Order is created. A clear owner for tax calculation must be defined; either BigCommerce must be configured to mirror Dynamics tax groups precisely, or it must send pre-tax values. The system should quarantine any order with an unmappable discount or tax variance for manual review.
Inaccurate inventory levels from multiple warehouses
Operational impact: When Dynamics 365 manages stock across multiple warehouses or legal entities, the integration often sends an incorrect availability figure to BigCommerce. This results in overselling popular SKUs, or conversely, showing items as out of stock when they are available elsewhere. This directly harms revenue and requires the customer service and fulfilment teams to manage order cancellations and exceptions.
Prevention / Action: Define a clear inventory availability strategy from the outset. Decide whether the integration should aggregate stock from all relevant Dynamics 365 warehouses into a single figure for BigCommerce, or if BigCommerce needs to be aware of different stock locations. The synchronisation logic must respect Dynamics 365's calculation of 'on-hand available' stock, accounting for existing reservations to provide an accurate figure to the storefront.
Product information synchronisation failures
Operational impact: Updates to product records in Dynamics 365 fail to publish correctly to the BigCommerce catalogue, or they create duplicate and inconsistent listings. This can involve pricing, variant details, or sales categories. The merchandising team spends significant time manually correcting data in BigCommerce, and incorrect data can lead to orders placed at the wrong price, which creates financial discrepancies and poor customer experiences.
Prevention / Action: Establish the SKU as the single, immutable identifier linking a 'Released Product' in Dynamics 365 to a 'Product Variant' in BigCommerce. The integration architecture must explicitly map the Dynamics item structure to the BigCommerce product model, including how variants and custom fields are handled. Implement robust error logging to flag any product record in Dynamics that fails validation against BigCommerce's requirements, preventing it from attempting to synchronise until the master data is corrected.
Delayed or partial dispatch notifications
Operational impact: Tracking numbers and dispatch confirmations from Dynamics 365 fail to update the BigCommerce order in a timely manner. When an order is split into multiple shipments in Dynamics, the integration may only update the BigCommerce order once, or not at all. This leads to a surge in 'where is my order?' queries for the customer service team and degrades the post-purchase experience.
Prevention / Action: The integration's order status updates must be triggered by the creation of a 'Posted Sales Shipment' record in Dynamics 365. The logic must be built to handle partial shipments, correctly passing the specific items, quantities, and tracking numbers for each individual dispatch back to the corresponding BigCommerce order. This ensures the customer receives timely and accurate dispatch information for every part of their order.
Mismatched customer account records
Operational impact: The integration creates duplicate customer accounts in Dynamics 365 when a returning customer uses a different email address or checks out as a guest in BigCommerce. This splits the order history across multiple records, preventing a single customer view. It corrupts marketing segmentation and makes it impossible for finance or customer service teams to accurately assess customer lifetime value or manage credit limits.
Prevention / Action: A clear matching strategy for customer records is required. Before creating a new customer record in Dynamics 365, the integration should first attempt to find a match based on a hierarchy of identifiers, such as email address and then a combination of name and postcode. Business rules must be defined for handling ambiguous matches, either by flagging them for manual review or by applying a default merging logic. This preserves a clean master customer list in the ERP.
Frequently asked questions
Which system should be the master for product information like SKUs and pricing?
In most successful implementations, Dynamics 365 acts as the master for the Item record, including the SKU, cost, and pricing data which then syncs to BigCommerce. This approach prevents critical data conflicts, as some platforms like BigCommerce can permit duplicate SKUs which would break financial processes and inventory tracking in Dynamics 365. Centralising product truth in the ERP ensures consistency between financial reporting and the live storefront catalogue.
Why can't we just continue with manual order entry into Dynamics 365 as we grow?
Manual entry of BigCommerce sales orders into Dynamics 365 creates a significant operational drag and risk of error as transaction volumes increase. This approach not only consumes finance team resources but also introduces keying errors that corrupt the order-to-cash process, leading to problems with stock allocation and payment reconciliation. Automating the creation of Sales Orders in Dynamics 365 from BigCommerce orders is fundamental to scaling gracefully.
How are customer refunds reflected in the accounts if they are initiated in BigCommerce?
A common point of failure is when a refund processed in BigCommerce does not automatically create the corresponding Credit Memo in Dynamics 365. This forces the finance team to perform manual adjustments to reconcile customer accounts and ensure the General Ledger is accurate. A properly configured integration ensures a BigCommerce refund immediately triggers the correct financial transaction in Dynamics 365, keeping the order history and accounts aligned.
Our promotional codes in BigCommerce don't match our financial dimensions in Dynamics. Is this a problem?
Yes, this is a frequent cause of reconciliation failures between BigCommerce and Dynamics 365. If a discount code used at checkout does not map to a valid financial dimension or rule in Dynamics 365, the sales order will either fail to sync or post with incorrect values. This requires manual correction by the finance team to ensure revenue is recognised correctly in the General Ledger.
If we hold stock in multiple warehouses in Dynamics 365, how does that show in BigCommerce?
The integration needs to correctly aggregate inventory levels from multiple warehouse locations in Dynamics 365 to publish a single, accurate 'available-to-sell' quantity to the BigCommerce SKU. A common failure is when a basic integration only syncs stock from a single default warehouse. This leads to BigCommerce showing items as out of stock when they are available in other locations, resulting in lost sales.
