Integration Agency & Consultants
At scale, the manual effort required to bridge B&Q Marketplace and Sage200 creates operational drag that finance and warehouse teams can no longer ignore. This integration ensures that B&Q Marketplace sales data fuels your core ERP processes without manual intervention. We focus on order-to-cash accuracy so your finance team can trust the numbers and your warehouse can fulfil orders without needing to remediate data mismatches.

Consulting
We connect your B&Q Marketplace Mirakl and Sage200 integration, supporting Marketplaces and ERP systems for efficient operations. Our consulting services are valuable because our system audit identifies inefficiencies and integration gaps between B&Q Marketplace Mirakl, Sage200, and other ERP or Marketplace platforms. This enables our consultants and your team to take decisive action, ensuring your technology ecosystem runs smoothly and efficiently, so you can deliver a great customer experience. Our audits provide the foundation for practical improvements and ongoing operational success.
Solution Design
The design for B&Q Marketplace and Sage200 prioritises order-to-cash accuracy and warehouse throughput. We designate Sage200 as the source of truth for inventory and financials, with B&Q orders posted to the ERP on a defined trigger. A primary design decision addresses the trade-off around sync frequency. We typically manage inventory updates on a schedule that protects Sage200 API stability during peak trading. This ensures warehouse teams work from a single queue in Sage200 while the marketplace updates automatically as orders are despatched. The design ensures finance closes the month using Sage200 data, confident that marketplace fees and gross sales are reconciled against B&Q settlement reports. This approach prevents reconciliation debt by aligning settlement data with original ERP sales invoices.

Surfacing order failures and inventory mismatches
Standard dashboards often hide the quiet failures that cause reconciliation gaps at month-end. Our approach focuses on operational visibility, surfacing individual order sync failures and inventory mismatches between B&Q and Sage200. We monitor for 'ghost orders' that appear in the marketplace but fail to post to the ERP due to validation errors. By capturing these exceptions early, your operations team can resolve address or SKU errors before they impact fulfilment times or financial reporting.
Enabling finance and operations team ownership
Handover focuses on the finance, operations and ecommerce teams who manage the daily cycle of B&Q Marketplace and Sage200. We provide operational documentation explaining where each data object lives and how to manage sync exceptions. Finance teams learn to reconcile B&Q settlements against ledger postings to manage reconciliation debt, while operations teams learn how to investigate failed order injections. Responsibility for each exception type is clearly defined to prevent ownership leakage. Training is anchored in the specific design decisions made for your business. Documentation is an operational reference for the people running the business, not a technical archive.
Protecting the financial source of truth
Post-launch, we provide ongoing operational ownership to maintain the financial trust boundary between systems. We monitor the order flow and inventory sync between B&Q and Sage200, resolving sync exceptions before they impact the warehouse. Support is focused on business continuity, ensuring your marketplace presence remains stable during peak periods. We monitor for data discrepancies that could lead to source-of-truth ambiguity. This ensures that reporting remains trustworthy and that any settlement drift is identified before month-end reconciliations are impacted.
Common failures
Inaccurate Product to SKU Mapping
Operational impact: When a B&Q Marketplace Offer ID fails to map to a Sage200 SKU, the order cannot post to the ERP. This creates a queue of orphaned orders that require manual repair. Delays in processing these orders risk breaching B&Q seller performance metrics and lead to reconciliation gaps where revenue in Mirakl fails to align with inventory costs in Sage200.
Prevention / Action: Designate Sage200 as the source of truth for all product master data. The integration must validate Mirakl Offer IDs against Sage200 SKUs before order creation. Automated alerts for mapping failures allow teams to fix master data at the source rather than patching individual orders.
Marketplace Fee and Payout Reconciliation Gaps
Operational impact: B&Q Marketplace deducts commissions and fees from payouts, creating a discrepancy between gross sales in Sage200 and the net cash arriving in the bank. Finance teams often resort to manual spreadsheets to account for these fees, creating reconciliation debt and slowing the month-end close.
Prevention / Action: The integration should process Mirakl settlement reports to map fee types to Sage200 nominal codes. Using a dedicated clearing account allows for the matching of gross sales invoices against net payouts, with the integration creating journals to account for deductions automatically.
Rejected Despatch Notifications
Operational impact: B&Q enforces strict carrier codes. If Sage200 sends a non-compliant carrier name, the Mirakl API rejects the update. The order stays "unshipped" in the B&Q system, damaging seller ratings and delaying customer notifications even when the goods have left the warehouse.
Prevention / Action: Use a transformation rule to convert internal Sage200 carrier names into valid B&Q codes. Monitoring must flag rejected despatches immediately so the fulfilment team can resolve the mismatch before it impacts seller performance.
Frequently asked questions
How does the integration help reconcile B&Q Marketplace payouts with our Sage200 financials?
Manually unpicking B&Q payouts to account for commissions, shipping fees, and VAT is a major time drain for the finance team. The integration automatically generates a summary journal entry in Sage200 from the Mirakl settlement report, allocating gross sales, fees, and VAT to the correct nominal codes. This removes hours of manual work from the month-end close process and ensures financial accuracy.
Our SKUs in Sage200 might not match B&Q's identifiers. How are orders mapped correctly?
This is a common source of orphaned orders, where a sale from B&Q Mirakl fails to create a sales order in Sage200. The integration uses a mapping table that links the unique B&Q 'Offer ID' to the correct SKU in your Sage200 item record. This ensures every order from B&Q Marketplace is translated into a valid Sage200 Sales Order without manual lookup or correction.
If we update stock in Sage200, how quickly is that reflected on B&Q Marketplace?
Sage200 acts as the source of truth for inventory, and keeping this synchronised with B&Q Marketplace is critical to prevent overselling and protect seller metrics. The integration pushes stock level updates from the Sage200 item record to the corresponding Mirakl offer on a defined, frequent schedule. This ensures the availability shown on B&Q closely matches your actual warehouse stock.
B&Q has strict requirements for carrier information. How does the integration prevent fulfilment update failures?
Failing to send a valid carrier name is a frequent cause of B&Q Marketplace rejecting a shipment confirmation, which damages seller performance metrics. The integration maps the carrier details from your Sage200 despatch process to the specific approved list of \"Carrier Codes\" that B&Q Mirakl requires. This ensures your fulfilment updates from Sage200 are always accepted without error.
When a customer requests a refund, how is that handled between B&Q Mirakl and Sage200?
Processing a refund on the B&Q portal typically creates a separate, manual task for the finance team to create a Credit Note in Sage200. The integration automates this by detecting the refund action in B&Q Mirakl and generating the corresponding Credit Note in Sage200 against the original Sales Order. This keeps your financial records and stock levels accurate without double-entry.
