SYSTEM INTEGRATION FOR ECOMMERCE
Modern ecommerce is the integration of 8–15 systems — storefront, ERP, CRM, PIM, OMS, 3PL/WMS, accounting, marketing platforms, analytics, support, and tax. 1Digital® builds the integration layer across NetSuite, SAP, Microsoft Dynamics, ShipStation, Klaviyo, Salesforce, HubSpot, Avalara, and the long tail of platform-specific connectors that hold the operation together.

Modern ecommerce is rarely a single platform — it's the integration of 8–15 systems that have to stay in sync for the operation to function. Storefront and checkout (Shopify Plus, BigCommerce, Magento), ERP (NetSuite, SAP, Microsoft Dynamics, Acumatica), CRM (Salesforce, HubSpot, Pipedrive), PIM (Akeneo, Plytix, Pimcore), OMS (Brightpearl, Linnworks, Cin7), 3PL / WMS (ShipBob, ShipStation, ShipHero), accounting (QuickBooks, Xero, NetSuite), tax (Avalara, TaxJar, Vertex), marketing (Klaviyo, Mailchimp, Iterable, Braze), support (Gorgias, Zendesk, Re:amaze), and analytics (GA4, Mixpanel, Heap, Triple Whale). When the integrations break, orders go missing, inventory desync floods support, and tax/accounting reconciliation eats finance team capacity.
1Digital® builds the integration layer with platform-native APIs, middleware (Celigo, Workato, MuleSoft where appropriate, custom code where not), event-driven architecture for real-time sync requirements, batch processing for high-volume nightly operations, idempotent error handling and retry logic, and observability tooling so integration failures surface before customers notice. The right integration architecture is the difference between an ecommerce operation that scales and one that adds support headcount with every new SKU and channel.
The typical mid-market ecommerce stack runs 8–15 systems that need integration: storefront (Shopify/BC/Magento), ERP (NetSuite/SAP/Dynamics), PIM (Akeneo or platform-native), OMS (Brightpearl/Linnworks/Cin7), 3PL/WMS (ShipBob/ShipStation), CRM (Salesforce/HubSpot), marketing (Klaviyo/Iterable), accounting (QuickBooks/Xero), tax (Avalara/TaxJar), analytics (GA4/Triple Whale/Heap), and support (Gorgias/Zendesk). Enterprise stacks add B2B portals, returns management, fraud screening, and ABM platforms.
Middleware is right when the use case maps cleanly to common patterns (Shopify → NetSuite, BC → SAP, standard CRM sync), when the integration runs at modest data volume, and when the customer's team can maintain it long-term. Custom code is right when the use case is highly specific to the business, when data volume exceeds middleware throughput, when integration logic includes complex transformations or business rules, or when middleware licensing economics don't pencil. Most engagements end up hybrid — middleware for the standard sync, custom for the specific.
Event-driven webhook architecture for real-time-required integrations (order creation → OMS, inventory updates → storefront, refund → accounting). Batch processing for nightly or scheduled syncs (catalog full-refresh from PIM, accounting reconciliation, marketing-list audience updates). The right pattern depends on freshness requirements, system throughput limits, and operational tolerance for delay — most ecommerce stacks need both patterns, not one or the other.
Idempotent operations (retries don't double-process), exponential-backoff retry logic, dead-letter queues for permanently-failed jobs, and observability tooling (Datadog, New Relic, platform-native logs, custom alerting) that surfaces failures before customers notice. The most common ecommerce ops failure mode is silent integration failure — order created but never synced to ERP, inventory updated but never reflected in storefront, refund processed but never reconciled in accounting. Observable integration architecture is the difference between catching issues immediately vs discovering them at month-end close.
Highly variable. Simple platform-native integrations (Shopify → Klaviyo, BC → HubSpot, GA4 setup): 1–4 weeks per integration. Mid-complexity (Shopify → NetSuite via Celigo, BC → ShipStation, custom PIM sync): 4–10 weeks per integration. Complex enterprise integration (custom ERP migration, full headless commerce backend integration, multi-system real-time sync architecture): 3–9 months as a structured engagement. Pricing depends on integration complexity, custom code requirements, and middleware licensing where used.
