BigCommerce ERP Integration Services for Growing B2C and B2B Stores
BigCommerce is an ecommerce platform that includes everything in a single subscription plan: your catalog, checkout, payments, security, and hosting. This solution provides APIs to integrate data with external systems. It also helps you sell products in both B2C and B2B models, offers multiple storefronts, and supports multiple currencies through one back-end system. When linked to your ERP system, it provides real-time inventory, pricing, and order information. PenguinPeak Technologies integrates this solution for you, with a Google rating of 5.0, a Clutch rating of 4.8, and a Trustindex rating of 5.0, plus technical expertise in BigCommerce and major ERPs.
What Our BigCommerce ERP Integration Covers
Catalog, variants, and options
We map products, variants, modifiers, categories, and brands to ERP items, so SKUs never drift.
Orders and payment management
Orders, payment status, refunds, and partial shipping all become clean ERP sales records without any duplicate customers. Inventory at each site moves into BigCommerce, with mechanisms to prevent the shop from selling what it can't ship.
Customers and customer groups
Each buyer has one record, and BigCommerce groups line up with your ERP pricing tiers. With B2B, companies, buyer roles, quotes, and invoices stay in step with the customer accounts your finance team already trusts. Set contract and promotional prices across all storefronts.
Integrate shipping, fulfillment, and accounting.
Tracking numbers, carrier information, and 3PL data flow back to the store, and finance tools like QuickBooks, Xero, and Zoho Books connect as well.
Headless and custom storefronts
We connect Catalyst front ends, custom apps, and middleware. If you need to build or move the store, our web development team works across React, Next.js, MERN, Shopify, WooCommerce, and Magento, and our UI/UX designers shape the buyer journey around your live ERP data.
Mobile ordering and field sales apps
Buyers can reorder from their phones and sales reps can check stock or raise quotes on the road, with Android, iOS, Flutter, or React Native apps reading and writing to the same ERP records.
AI on top of clean data
Once orders, stock, and customers align across systems, our AI and machine learning team can add demand forecasts, product recommendations, and assistants that answer questions about orders and stock.

Stencil, Catalyst or B2B Edition: What Changes for the Integration
Stencil themes are the hosted storefront. The ERP link sits behind them, and the design never touches your data flow.
Catalyst is BigCommerce’s headless architecture, built with Next.js, React, and GraphQL. Although Catalyst connects to the ERP through the BigCommerce API, you must ensure the cached page shows the correct inventory and pricing.
B2B Edition adds company accounts, buyer roles, price lists, quotes, and invoice payments. Each needs a matching ERP record, so mapping is the most important step.
From First Call to Steady State
- Review. We review your ERP, BigCommerce plan, apps, and price rules.
- Blueprint. You sign off on the field map and who owns records in the system.
- Build in the sandbox environment. We run tests on flows using real orders, even tricky ones.
- Phased launch. Orders go live first, then inventory, then prices and customers.
- Observation phase. We observe carefully and give you clear documentation.
Built for How Each Market Trades
Stores in New Zealand, India, the US, the UAE and Australia rarely run the same way. We set up regional price lists, local currencies, and nearby warehouses in the ERP, so each storefront shows the right price and stock to its own buyers. Our team covers Auckland, Mumbai, the UAE, and US working hours, so we address sync issues while your store is still trading.
When BigCommerce and Your ERP No Longer Agree
1
Out-of-stock products being listed as available for purchase
Delays in stock information, or duplicative warehouse counts. We sync stock per warehouse per product and maintain a small buffer on high-selling products.
2
One customer, multiple records
Guest orders and repeat customers frequently create duplicates. We match records using email and company name before creating a new record.
3
Products with incorrect prices or SKUs
BigCommerce product variants won't always map to ERP items without additional work. An approved field map associates variants with individual ERP items.
4
Refunds that are processed through the store but not the accounting ledger
This is common when many organizations set up refunds as a type of order. We automate credit note generation and associate it with the original sale.
5
Statuses that work against each other
Each system has its own levels; therefore, we create a common status, and “shipped” means the same thing in both systems.
6
B2B customers receiving incorrect prices in contracts
The pricing list becomes unaligned once it’s edited in two places. We maintain one pricing source and apply updates to BigCommerce.
Frequently Asked Questions
The BigCommerce ERP integration links your ecommerce store to the system that handles accounting, inventory management, and fulfillment through a two-way data exchange. Orders, customer information, and transactions go from BigCommerce to the ERP, and stock information, product pricing, shipping information, and invoices are sent back. You can accomplish the integration via the BigCommerce APIs, a middleware platform, or a connector solution.
BigCommerce integrates with NetSuite, SAP, Microsoft Dynamics 365 Business Central, Acumatica, Odoo, and Sage, as well as accountants like QuickBooks, Xero, and Zoho Books. This depends on your stock management needs, order volume, and plans. We review your current situation and give an honest opinion on whether a simpler solution will do.
Yes. BigCommerce supports three types of APIs: REST, GraphQL, and Webhooks, which alert you to events such as order creation. Rate limiting depends on the store type: Standard and Basic store types allow 150 requests per 30 seconds, while the Pro store allows 450 requests per second. Exceeding these limits returns a 429 HTTP status code from the API.
Yes. In B2B Edition, we have added company accounts, buyer types, price lists, quotations, and invoice payments, and all of them should correspond to the ERP system. We map company accounts to ERP customer accounts, price lists to ERP pricing levels, and quotations to sales orders, and keep everything in sync. As a result, the agreed-upon price will automatically appear for the buyer.
The pre-configured connector will work well for order and inventory processes that require little customization. The custom connector and middleware will support multiple warehouses, contract pricing, B2B Edition, or large order volumes. We will evaluate both based on your needs and choose the more cost-effective option in the long run.
A typical ordering and inventory flow takes 6-12 weeks, but factors like business-to-business pricing, multiple storefronts, or additional customization can extend the timeline. The cost depends on the amount of work involved in terms of the ERP system, number of flows, custom fields, or whether middleware is required. We give a fixed scope quote after discovery.
Any unsynced data is placed in the queue and retried without alerting your team. We will monitor the webhooks because BigCommerce can disable yours if the webhook keeps failing. Our connection uses OAuth access tokens with restricted permissions for secure transport of data from checkout to accounting.
