01 · What you get

What a Microsoft Dynamics 365 integration gives you.

Finance closes on time

Invoices, credit notes and refunds reconcile automatically to Dynamics 365 without manual lookup. Reconciliation dashboard surfaces exceptions before month-end so your finance team closes with confidence.

Stock is trusted across channels

Inventory publishes from Dynamics 365 to storefronts, marketplaces and point-of-sale in sync. Oversell is prevented, backorder messages are accurate, and reserve logic protects peak trading periods.

Orders flow without bottlenecks

Web orders land in Dynamics 365 automatically, validated against credit and stock rules, and acknowledged back to customers in real time. Manual order entry is eliminated; exceptions are flagged visibly.

Customer credit is enforced

Credit limits and payment terms from Dynamics 365 are published to checkout so transactions respect your risk policy. Blocked orders surface in an exception queue for manual review, not silent failures at capture.

Pricing governance is unified

Base prices, customer-specific tiers and promotional bands are maintained in Dynamics 365 and published to commerce channels. No conflicting prices across channels, no manual price overrides breaking your margin.

02 · When it's worth it

Where a Microsoft Dynamics 365 integration earns its place.

If two or more of these are true, the integration usually pays for itself quickly.

Publishing stock availability and base list pricing from Dynamics 365 to multiple commerce channels in real time
Capturing web orders from storefronts into Dynamics 365 with acknowledgement and validation back to the shopper
Synchronizing customer accounts, credit limits and payment terms from Dynamics 365 to checkout and post-order processes
Returning invoices, credit notes and dispatch confirmations from fulfilment back to Dynamics 365 for revenue recognition
Reconciling commerce transactions against Dynamics 365 finance records to close the month with confidence
03 · The limits

Where off-the-shelf connectors fall short.

Vendor connectors are fine for simple cases. Here's where the real ones need more.

No native real-time stock sync

Dynamics 365 does not publish stock changes to commerce channels without integration logic. Manual batch exports or third-party middleware are required to keep availability current during peak trading and prevent overselling across channels.

Order acknowledgement requires custom logic

Dynamics 365 does not automatically confirm or reject web orders back to storefronts. Custom workflows must evaluate credit, inventory and policy rules, then post acknowledgement or rejection messages so the shopper knows their order status.

No channel-specific pricing rules

Dynamics 365 holds base pricing and customer tiers, but does not natively adapt pricing per marketplace or promotional campaign. Integration logic must map Dynamics 365 prices into channel-specific bands, discount matrices and regional variants.

Finance reconciliation is manual

Matching commerce transactions to invoices and credit notes in Dynamics 365 requires custom reports and exception handling. Without integration, month-end reconciliation relies on spreadsheets and manual lookup across systems.

Payment capture and refund status is incomplete

Dynamics 365 does not natively track payment authorization, capture and refund events from your payment processor. Custom logic is needed to post capture confirmations and refund receipts back to Dynamics 365 for accurate cash position and accounts receivable.

04 · The real work

The gap between order capture and finance reconciliation is where integration ownership gets ambiguous: does the commerce platform or Dynamics 365 own the money, and who confirms when both agree?

05 · Where it sits

Where this integration sits in your estate.

Microsoft Dynamics 365 holds the commercial record. The iWeb integration layer manages the rules, mappings, monitoring and exceptions. The commerce platform presents the customer-facing experience. The estate map helps agree ownership before anything is built.

Commerce platform agnostic. Connect Microsoft Dynamics 365 across your entire technology stack.

07 · Data flows

The data flows we wire.

Each flow has a direction and an owner. We agree both before a line of code is written.

→Into ERP
←From ERP
↔BOTH WAYS
Stock and pricing export: Inventory availability, base pricing, customer-specific pricing and promotional bands flow from Dynamics 365 to commerce systems hourly or on demand
Perishable data like stock buffers for peak trading are calculated and published to prevent oversell.
Web order ingestion and validation: Orders captured from your storefront (with shipping address, payment method and customer reference) are posted into Dynamics 365 as sales orders
Validation rules check credit limits, product availability and customer account status before order acknowledgement is sent back to the shopper.
Customer and credit updates: Customer master data, credit limits, payment terms and account holds from Dynamics 365 are exported to commerce platforms so checkout teams can enforce credit policy and flag high-risk transactions for manual review.
Invoices and credit notes: Once orders are fulfilled and goods despatched, invoices and credit notes are generated in Dynamics 365 and returned to commerce systems for customer visibility, accounting trail and subscription renewal triggers.
Returns and refund reconciliation: Return authorizations flow from commerce to Dynamics 365; credit notes and refund status flow back to update customer records and trigger payment reversals through your payment processor.
08 · How we build it

How iWeb configures the integration around your business.

Same method on every integration. The decisions come before the code.

  1. 01
    Design order and stock sync patterns

    We map your Dynamics 365 business logic into integration workflows: which orders need credit approval, how stock buffers are calculated per channel, when pricing refreshes trigger, how payment captures are posted back.

  2. 02
    Build resilient data pipelines

    We construct ETL flows that handle Dynamics 365 API rate limits, batch processing and downtime without data loss. Orders queue safely; stock syncs retry intelligently; reconciliation files arrive daily with validation reports.

  3. 03
    Implement exception handling and monitoring

    We set up dashboards for unacknowledged orders, reconciliation mismatches and sync latency. Exception queues name responsible teams so issues are resolved quickly, not discovered during month-end audit.

  4. 04
    Handle payment and refund flows

    We build bidirectional payment sync so authorization and capture events from your payment processor update Dynamics 365 cash position, and refunds flow back to payment systems with matching credit notes.

  5. 05
    Support multi-channel pricing and stock

    We manage channel-specific pricing rules, stock allocation matrices and promotional variants so Dynamics 365 publishes accurately to Magento, Shopify, BigCommerce, marketplaces and point-of-sale simultaneously.

10 · Experienced integrator

Built this before

iWeb has architected dozens of Dynamics 365 integrations into ecommerce estates. We understand how stock, pricing, customer credit and orders flow between Dynamics 365 and storefronts, and how to keep finance and commerce teams confident in their data without manual reconciliation.

Familiar with Dynamics 365 API patterns, rate limiting, authentication and common integration pitfalls.
Understand how order validation logic (credit, inventory, customer account) sits at the boundary between commerce and finance, and how to name owners for each rule.
Built payment capture and refund sync so Dynamics 365 cash position stays accurate through the payment lifecycle.
Have designed multi-channel stock and pricing exports so aggregated commerce demand does not overcommit Dynamics 365 inventory, and regional or promotional pricing variants do not break base prices.
Know how to make Dynamics 365 downtime non-blocking for storefronts and build exception queues that surface unacknowledged orders clearly.
11 · Before launch

What we test before launch.

Every one of these is rehearsed before a customer ever sees the integration.

Confirm orders with various credit statuses (approved, on hold, declined) are routed correctly and rejection reasons reach the shopper.
Verify stock availability publishes to commerce channels at scheduled intervals and manual triggers work without data loss.
Test payment capture and refund status flow from your processor back to Dynamics 365 and reconcile against invoices.
Simulate Dynamics 365 downtime and confirm orders queue locally in commerce, then replay cleanly when Dynamics 365 recovers.
Validate customer-specific pricing exports match Dynamics 365 rates and channel-specific overrides do not get clobbered on refresh.
Check reconciliation dashboard flags mismatches (unmatched refunds, duplicate orders, stale invoices) before month-end.
Confirm multi-channel orders (marketplace, direct, point-of-sale) route to Dynamics 365 with channel identifiers intact for fulfillment.
12 · Failure points

Common risks and where they bite.

We name these on day one. A risk written down is a risk you can plan around.

Stock goes stale during peak trading

If stock sync between Dynamics 365 and commerce platforms runs infrequently or fails silently, inventory becomes inaccurate during Black Friday or seasonal spikes. Customers see availability that no longer exists; orders cannot be fulfilled.

Orders are lost or duplicated

Web orders may fail to reach Dynamics 365 if the integration crashes, or may arrive twice if retry logic is not idempotent. Lost orders damage customer trust; duplicate orders create billing chaos and inventory write-offs.

Credit limits are not enforced in checkout

If customer credit data from Dynamics 365 publishes late or not at all to checkout systems, high-risk transactions sail through and you end up with uncollectable receivables or chargebacks.

Pricing is inconsistent across channels

If Dynamics 365 pricing exports do not account for channel-specific rules, discounts or regional variants, customers see different prices on different storefronts or marketplaces. Margin erosion and brand confusion follow.

Finance reconciliation drifts month to month

If payment captures, refunds and credit notes do not sync reliably back to Dynamics 365, reconciliation requires manual lookup and spreadsheets. Unmatched transactions pile up; month-end close slips.

Dynamics 365 downtime stops checkout

If commerce platforms cannot validate credit or retrieve stock without a synchronous call to Dynamics 365, outages in Dynamics 365 break shopper checkout. Orders are lost; revenue stops.

14 · Questions

Common questions about Microsoft Dynamics 365 integrations.

How does iWeb handle orders that fail Dynamics 365 validation (credit, stock, customer)?

Failed orders are rejected and queued in an exception dashboard visible to your order management team. The rejection reason (credit hold, out of stock, invalid account) is sent back to the shopper so they know why their order was declined. Manual review or resubmission is then possible.

What happens if Dynamics 365 is unavailable when a shopper completes checkout?

We design the integration so checkout does not depend on a synchronous call to Dynamics 365. Orders are queued locally in your commerce platform and replayed to Dynamics 365 when it recovers. Until replay, stock and credit checks are performed against a cached snapshot, and the shopper receives order confirmation with a caveat about fulfillment confirmation.

How frequently does stock sync from Dynamics 365 to our commerce channels?

We typically design stock sync to run hourly, with ability to trigger on-demand for critical SKUs during peak trading. Real-time sync is possible for high-velocity channels if your integration infrastructure supports it. The sync frequency is configurable and monitored so you can adjust for seasonal demand or inventory volatility.

Who owns customer-specific pricing rules, and how are they published?

Base prices and customer tiers are maintained in Dynamics 365 by your pricing team. Channel-specific overrides, bundle pricing and promotional campaigns are managed in your commerce platform or PIM. We build the mapping so Dynamics 365 prices flow to channels accurately, and channel teams can layer overrides without breaking the integration.

How do we reconcile payments and refunds between our payment processor and Dynamics 365?

We build daily reconciliation flows that match payment captures from your processor to invoices in Dynamics 365, and refunds back to credit notes. Mismatches are flagged in an exception report so your finance team can investigate before month-end. Payment authorization status is also posted back to Dynamics 365 so cash position is accurate.

What happens if the same order arrives in Dynamics 365 twice by mistake?

We build idempotent order ingestion using order reference as the unique key. Duplicate orders are detected and discarded before they create duplicate invoices or inventory movements. Idempotency also protects against retries when the original order succeeded but the confirmation message was lost.

How do credit holds and payment term changes in Dynamics 365 reach the checkout?

Customer master data and credit limits are exported from Dynamics 365 daily and published to your checkout system. When a credit hold is placed or payment terms change, the export picks up the change and checkout applies it within 24 hours. High-priority credit changes can trigger on-demand refresh for faster propagation.

How are returns and refunds managed between commerce platforms and Dynamics 365?

Return authorizations flow from your commerce platform or OMS into Dynamics 365. Once the return is received and inspected, a credit note is generated in Dynamics 365 and returned to the commerce platform, triggering a refund to the customer's original payment method. The refund is reconciled back to Dynamics 365 for cash accuracy.

Can we run the integration if we sell through multiple marketplaces and direct storefronts?

Yes. We design the integration to aggregate orders from all channels (BigCommerce, Shopify, Amazon, etc.) into a single order flow to Dynamics 365. Stock and pricing are published from Dynamics 365 out to all channels. Channel-specific fields (marketplace order ID, fulfillment instructions) are preserved so orders can be routed accurately.

What observability and monitoring do we get once the integration is live?

We set up dashboards showing order ingestion rates, validation failure reasons, stock sync latency, reconciliation mismatches and payment status exceptions. Alerts fire if sync fails or latency exceeds SLA. Daily summary reports go to operations and finance so teams stay aware of integration health and exception backlog.

How do we handle promotional pricing or seasonal discounts in a multi-channel environment?

Base pricing comes from Dynamics 365; promotional variants are managed in your commerce platform or PIM and layered on top without overwriting the integration. We ensure Dynamics 365 price changes do not clobber promotions, and we flag conflicts so your merchandising team can resolve them. Promotional start/end dates are also monitored to prevent stale discounts.

What happens when Dynamics 365 introduces a new field or changes a field definition?

Schema changes in Dynamics 365 are mapped into the integration; we document which fields are in scope and which are ignored. If you add a new customer attribute in Dynamics 365, we extend the export to include it and test it against your commerce platforms before going live. Breaking schema changes (field removal, type change) require integration review and testing.

How do we migrate historical order and customer data from our old system to Dynamics 365 before going live?

Data migration is a separate workstream. Once historical data is loaded into Dynamics 365 by your implementation partner, we set a sync cutoff date so the integration ingests only new orders and pricing changes going forward. We validate the cutoff and reconcile Dynamics 365 against your legacy system for a period to confirm accuracy before cutover.

Can the integration handle customer-specific pricing at the line item level?

Yes. Dynamics 365 customer pricing can be defined at the product or product-category level. We export that pricing to commerce checkout so customer-specific prices are applied correctly. Line-item overrides (one-off discounts) are typically managed in the OMS or approved by a sales team, not auto-synced from Dynamics 365.
