BigCommerce Integration Services
Connect your store to every system that runs your business
Your ERP holds pricing authority. Your CRM owns the customer record. Your third-party logistics partner manages inventory truth. Redefine wires them all into BigCommerce so your team stops rekeying data and starts shipping faster.

The real cost of disconnected systems
Your ops team is the integration right now
When BigCommerce and your ERP do not talk, someone on your team is the bridge. They export CSVs. They rekey order numbers. They reconcile inventory counts at 6pm before a sale goes live. That is not a people problem. It is a systems problem.
After integration, your systems agree in real time. Inventory flows from your warehouse to your storefront without a spreadsheet in between. Orders route to fulfillment the moment they clear payment. Customers get status updates from your CRM, not your support queue.
Time back to ops
14 hours
Average weekly manual hours eliminated per operations role
after ERP integration — no more CSV exports or rekeying order
numbers by hand.
Inventory accuracy
98%
Inventory accuracy rate after real-time BigCommerce to
warehouse sync — your storefront and warehouse agree on stock
counts without a 6pm reconciliation run.
Fulfillment speed
3x
Faster order-to-fulfillment cycle time with automated routing
logic — orders reach the warehouse the moment payment clears,
not after someone forwards a spreadsheet.

Scope and deliverables
What your integration covers
Every project is scoped around your specific data model. Here is what is included in a standard integration engagement.
ERP integration
Price books, purchase orders, inventory levels, and customer accounts flow between BigCommerce and your ERP in real time. Your ERP stays the pricing master. BigCommerce stays the order master.
Real-time inventory syncOrder write-backCustomer account syncPrice tier mapping
See BigCommerce ERP integration services →CRM integration
Order history, lifetime value, and behavior events push from BigCommerce into your CRM so sales and customer service see the full customer picture.
See CRM integration →PIM integration
Product attributes, enriched content, and digital assets publish from your PIM directly to BigCommerce catalog on schedule or on event.
See PIM integration →Custom API integration
Legacy systems, proprietary backends, and third-party tools without native connectors get custom-built, documented API bridges with error alerting included.
Third-party logistics and operations integration
Orders route from BigCommerce to your 3PL, warehouse management system, or fulfillment partner the moment they clear payment. Tracking numbers, shipment events, and return status come back automatically.

Client proof
From manual chaos to $70M in integrated commerce

Problem
Inventory, orders, and customer data lived in four disconnected systems. Manual reconciliation consumed hours per day and errors caused stockouts during peak seasons. No single source of truth existed for the operations team.

Why Redefine
Most integration pages are thin. Our work is not.
Other implementation partners offer generic connector installs. Redefine builds around your exact data model, business rules, and team workflow.

Budget guidance
What BigCommerce integration services cost
Scope drives cost more than system type. These ranges reflect real project data. Full detail is on the BigCommerce integration cost page.
Value calculation: hours saved per week multiplied by hourly team cost, plus downtime risk avoided, equals integration value versus fee.
Single system
$4k to $12k
One system connected. Standard data objects. Limited custom fields. 4 to 6 week timeline.
- One integration endpoint
- Data mapping and documentation
- 30-day hypercare
Most common
Multi-system stack
$15k to $45k
2 to 4 systems connected with custom logic, middleware, and error handling. 6 to 10 weeks.
- Full data model documentation
- Conflict resolution rules per object
- Real-time alerting and retry logic
- 30-day hypercare
Enterprise architecture
$50k+
5 or more systems, legacy backends, B2B pricing logic, or phased rollouts requiring an orchestration layer.
- Custom middleware orchestration
- Phased rollout planning
- Managed services retainer option
Submit brief → call within 48 hours → scoped proposal in 3 days → Sprint 1 within 1 week of sign-off
Your team's involvement across a full integration build is typically 3 to 5 hours per week, one data model review, async feedback on mapping documents, and a final staging sign-off. We handle everything else.
Common questions
What teams ask before scoping a BigCommerce integration
Answers to the questions your COO, IT lead, and operations team raise in the first conversation.
Most BigCommerce integrations go live within 4 to 8 weeks depending on the system type, data volume, and the number of data objects being synced. ERP projects with complex pricing logic or multi-warehouse routing take longer than CRM or email platform connections.
Redefine builds BigCommerce integrations for Microsoft Dynamics 365, NetSuite, SAP Business One, Sage, QuickBooks, and custom ERP systems with available APIs. Each integration is built around your specific data model, not a generic connector template.
Native connectors handle standard data objects out of the box but often break on custom fields, tiered pricing, or non-standard fulfillment rules. Custom API integrations are built around your exact data model and business logic, giving you control over every sync rule and conflict resolution strategy.
We define a master-of-record policy for every data object during the scoping phase. Price authority lives in the ERP while order status authority lives in BigCommerce. Conflict rules are documented, tested in staging, and reviewed with your team before any live data flows.
Every integration project includes a 30-day hypercare period with priority response. After hypercare, you can move to a managed services retainer for ongoing monitoring, error alerting, and planned enhancements, or continue on a project basis for new integration work.
Is this the right fit?
Honest about who we build for
We do our best work with teams that want a documented, maintainable integration, not a one-time connector install.
Good fit for...
- Stores doing more than $1M annually that have outgrown manual data workflows
- Teams with an ERP, CRM, or 3PL that needs to talk to BigCommerce in real time
- Operators who want full documentation and master-of-record rules, not a black box connector
- Operations leads who have tried native connectors and hit their limits
Not a fit if...
- You are pre-revenue or have no external system to connect to
- You need a one-time export script with no ongoing sync requirements
- You need a live integration in under two weeks with no scoping time available
- Your system has no available API or webhook capability
