eCommerce Integrations

Sell wherever your customers are, and run it all from one accurate set of orders, stock counts and customer records.

Selling on several channels is the easy part. Trouble starts when inventory, orders, customers and financials have to stay in sync across Shopify, BigCommerce, WooCommerce, Amazon and your backend systems. We build the integrations that keep all of it accurate, so each new channel adds sales without adding another list of manual updates for your team.

Why eCommerce Integration Matters

Each sales channel you add multiplies the data your operations have to handle. Without proper integration, orders sit in queues, stock counts drift from reality and customer data scatters across platforms. With your channels tied to your backend, you fulfill faster, oversell less and can measure profit by channel as well as revenue.

Common Challenges We Solve

Multichannel Inventory Chaos

You sell on Shopify and Amazon, but inventory lives in spreadsheets or a separate system. Overselling happens weekly, and stockouts cost you marketplace ranking.

Order Processing Bottlenecks

Each channel needs its own fulfillment rules, tax treatment and customer messages. Your team spends more time routing orders than filling them.

Product Data Inconsistency

Prices, descriptions and attributes differ from channel to channel because no single system holds the correct version. One update means logging into three or four platforms.

No Unified Customer View

Someone who buys on your website and on Amazon looks like two people in your systems. You can’t personalize marketing or track lifetime value accurately.

Our Approach

We trace every point where your sales channels touch your operational systems. That shows where data should flow, what has to change along the way, and where the work still depends on someone’s hands. The integrations we build cover the messy cases your business really sees, along with the orders that go smoothly.

What We Deliver

Order Flow Automation

Orders from Shopify, BigCommerce, WooCommerce, Amazon, Walmart and other channels reach your ERP or fulfillment system automatically, with correct tax, shipping and customer data.

Inventory Synchronization

One inventory pool updates across every channel in near real time. When stock moves in your warehouse, every storefront shows the change within minutes.

Product Information Sync

Manage product data in one place and push pricing, descriptions, images and variants to every channel. You no longer log into four dashboards to change a price.

Customer Data Unification

We merge customer records across channels into your CRM or ERP, giving you one profile per customer with their full order history.

Returns and Refund Automation

Return requests, refunds and restocking move through your systems without manual work, which keeps your financials and stock levels accurate.

From Channel Audit to Cutover

1

List Every Channel

We inventory each sales channel and backend system, then document how data moves between them and where delays and errors start.

2

Plan the Flows

Next come the data flows, the integration platform, the field mappings and a plan for what happens when a sync fails.

3

Test Real Orders

Real orders and inventory movements go through the build, including partial shipments, backorders, marketplace rules and sudden bursts of volume.

4

Cut Over

We switch to live data, watch every flow, fix issues right away and leave your team with documentation and alerts.

Why Choose System Strats

We have connected eCommerce platforms to ERPs, warehouses and accounting systems for businesses doing real volume. We know how marketplace connections behave and which fulfillment cases break simple integrations, so we build for how your business really operates.
