Hire Integration Developers and Consultants
Our integration experts have connected stores to ERPs, CRMs, warehouses and accounting systems for businesses across retail, B2B wholesale and manufacturing. We work directly with official platform APIs and webhooks, so your integrations stay supported after platform updates.
We also act as your consultant. We help you decide which system owns each piece of data, how often it should sync, and what should happen when something fails, so the integration is easy to maintain later.
How We Map Your Data Between Systems
Before we build, we agree on a data-mapping sheet with you. It shows which system owns each record, which way it flows, how often it syncs and how fields are transformed. Below is a typical store-to-ERP and store-to-CRM mapping.
| Data object | Store field (example) | ERP / CRM field (example) | Direction | Sync frequency | Transformation / rule |
|---|---|---|---|---|---|
| Product | SKU | Item Number | ERP → Store | On change | Exact match; SKU is the unique key |
| Product | Price | List Price / Price List | ERP → Store | On change | Currency and tax-inclusive rules applied |
| Inventory | Stock Quantity | Available Qty (per warehouse) | ERP → Store | Every 5–15 min | Sum of selected warehouses, minus safety stock |
| Customer | Contact Email / Customer ID | Store ↔ CRM | Real-time (webhook) | Email used to find duplicates before create | |
| Customer | Customer Group | Price Tier / Account Type | ERP → Store | Daily | Lookup table: ERP tier → store group |
| Order | Order ID | Sales Order Number | Store → ERP | Real-time (webhook) | Prefix added, e.g. WEB-10045 |
| Order | Line items (SKU, qty, price) | Sales Order Lines | Store → ERP | Real-time | Discounts split per line |
| Order | Order Status | Order / Fulfilment Status | ERP → Store | Every 15 min | Status lookup, e.g. Released → Processing |
| Shipment | Tracking Number, Carrier | Delivery Note / Tracking | ERP → Store | On change | Triggers customer shipping email |
| Invoice | Invoice / Payment | AR Invoice / Payment Receipt | Store → ERP | Real-time | Payment method mapped to GL account |
| Refund | Credit Memo | Credit Note / Return Order | Store → ERP | Real-time | Restock flag sent with each line |
WE OFFER A WIDE RANGE OF Ecommerce Integration Services
Our ecommerce integration services are built to make your store, ERP, and CRM work as one system — from a simple order export to a two-way, real-time sync that keeps running when order volume grows.
ERP integration
We connect your store with SAP, Microsoft Dynamics, NetSuite, Odoo, and other ERPs. Products, prices, and stock flow to the store; orders, invoices, and refunds flow back — without manual entry.
CRM integration
Customers and orders sync with Salesforce, HubSpot, or Zoho, so sales and support see the full buying history. See our Salesforce development and HubSpot CRM services.
Payment, shipping and tax integration
We connect payment gateways, shipping carriers, and tax tools to your checkout, so rates, labels, and tracking numbers update on their own. Read more on payment gateway integration for an ecommerce website.
Marketplace and PIM integration
Sell on Amazon and eBay from one catalogue. We sync product data from PIM tools like Akeneo to your store and marketplaces, and bring marketplace orders back into one place.
Custom API and middleware development
When a ready connector does not cover your needs, we build custom middleware on REST and GraphQL APIs — with queues, batching, and retry logic, so syncs keep working during sales peaks and API rate limits.
Integration support and monitoring
After launch, we monitor sync logs, fix failures quickly, and update your integrations when platforms release new API versions — so a failed sync never goes unnoticed.
BigCommerce Integration Services
As a certified BigCommerce partner, we connect BigCommerce stores to the business systems behind them. We use BigCommerce webhooks for real-time events, and the Catalog API to bulk import products and variants and to query and filter large product catalogs. A good example is our guide on integrating BigCommerce with Salesforce CRM for order sync. Our BigCommerce development team builds and maintains each connection.
- BigCommerce ERP Integration
- BigCommerce CRM Integration (Salesforce, HubSpot)
- BigCommerce Webhooks & Real-Time Order Sync
- Catalog, Price List & Inventory API Sync
- B2B Edition & Multi-Storefront Integrations
- Custom BigCommerce App Development
ERP & CRM Integration Solutions
Our integration experts have connected stores to ERPs, CRMs, warehouses, and accounting systems for businesses across retail, B2B wholesale, and manufacturing. We also act as your consultant. We help you decide which system owns each piece of data, how often it should sync, and what should happen when something fails — so the integration is easy to maintain later. The same approach works on every platform; see how we integrate Shopify and Salesforce with a Shopify webhook.
- Product, Price & Stock Sync (ERP → Store)
- Order, Invoice & Refund Sync (Store → ERP)
- Customer & Customer Group Sync (Store ↔ CRM)
- Shipment & Tracking Updates
- B2B Price Tiers & Account Types
- Warehouse & Accounting System Sync
How We Map Your Data Between Systems
Before we build, we agree on a data-mapping sheet with you. It shows which system owns each record, which way it flows, how often it syncs, and how fields are transformed. Every mapping includes logging, retry on failure, and email alerts. Field names vary by system, so we finalise them during requirement gathering. A typical store-to-ERP and store-to-CRM mapping looks like this:
- Product — SKU and price flow ERP → Store, on change
- Inventory — available stock per warehouse flows ERP → Store, every 5–15 minutes
- Customer — email and customer ID sync Store ↔ CRM in real time (webhook)
- Customer Group — ERP price tier maps to store customer group, daily
- Order — order ID, line items and discounts flow Store → ERP in real time
- Order Status & Shipment — status, carrier and tracking number flow ERP → Store
- Invoice & Refund — payments and credit notes flow Store → ERP in real time
API, Webhook & Automation Development
We use ready connectors where they fit and build custom middleware where they don’t, so you only pay for what you need. For lighter workflows, our Zapier developers set up no-code automation — like a BigCommerce and Google Sheets integration through Zapier. For heavier loads, we build on official REST and GraphQL APIs. See how BigCommerce API updates help business.
- REST & GraphQL API Integration
- Webhook Setup & Verification
- Custom Middleware & Connectors
- Zapier / Make Automation
- Queues, Batching & Retry Logic
- Sync Logs, Alerts & Monitoring

What Ecommerce Integration Services do we offer to our clients?
We offer end-to-end ecommerce integration services: ERP integration, CRM integration, payment, shipping and tax integration, marketplace and PIM integration, custom REST and GraphQL API development, webhooks, Zapier automation, data mapping, and ongoing monitoring. Whether you need a simple order export or a two-way, real-time sync, we can build it.
Why are we the best ecommerce integration company for you?
Because we understand both ecommerce platforms and back-office software. Every project starts with a signed-off data-mapping sheet, which avoids rework and duplicate records. You get the mapping sheet, test results, and sync logs, so you always know what data is moving and why — backed by an established agency serving clients across 25+ countries.
Which systems can you integrate with my store?
We connect Magento, BigCommerce, Shopify, Shopware, and WooCommerce with ERPs such as SAP, Microsoft Dynamics, NetSuite, and Odoo, CRMs such as Salesforce, HubSpot, and Zoho, plus payment, shipping, PIM, and marketplace tools.
What is a data-mapping sheet and why do I need one?
It is a document that lists every field being synced, which system owns it, the sync direction, frequency, and any conversion rules. It prevents duplicate records and wrong prices, and makes the integration easy to maintain.
Do you use ready connectors or custom code?
Both. If a reliable connector covers your needs, we configure it. If not, we build custom middleware using the platforms’ official APIs and webhooks.
Is the sync real-time?
Orders and customers usually sync in real time through webhooks. Stock and prices typically sync every few minutes, depending on your ERP’s API limits. Here is how to set up and verify BigCommerce webhooks.
What happens if a sync fails?
Failed records are logged and retried automatically. If a retry still fails, your team gets an alert with the record and the reason.
How long does an integration project take?
A standard single-system integration usually takes 3–6 weeks, including mapping, development, and testing. Multi-system projects are planned in milestones.
