Shopify B2B ERP Integration
For Australian wholesalers and distributors running NetSuite, Business Central, MYOB or Cin7. We sync accounts, contract pricing, stock and invoices two ways so your team stops re-keying orders.
When Shopify and your ERP disagree, someone pays for it
Trade buyers expect their prices, their stock and their terms. If that data lives in the ERP but not in Shopify, the gap gets filled by manual work and mistakes.
Prices live in two places
Contract and volume pricing sits in the ERP, while Shopify shows list prices. Reps quote by memory or hold orders back.
Orders re-keyed by hand
Every B2B order is typed into the ERP a second time. Slow, and one wrong SKU becomes a wrong invoice.
Stock drifts and oversells
Inventory isn't shared across warehouses in real time, so wholesale accounts order stock you can't actually ship.
Invoices and terms are invisible
Buyers can't see open invoices, credit limits or account balances, so your AR team fields the same emails all week.
New accounts stall
Trade applications are approved and set up manually, adding days before a buyer can place their first order.
Tax and catalogues out of sync
GST rules and account-specific catalogues differ between systems, and reconciling them at month-end is a scramble.
What sits where
A clear split before we start, so nothing falls through the gap between teams.
| Nexly delivers | You provide | Out of scope | |
|---|---|---|---|
| Integration layer | Build, mapping, testing, deployment | ERP sandbox and API access | ERP licence or module changes |
| Data model | Field mapping and sync rules | Master data cleanup | Historical migration (scoped separately) |
| Pricing | Contract and volume price sync | Maintained price lists in the ERP | Manual per-order discounting |
| Support | Monitoring, alerts, 30-day warranty | A named operations contact | In-house ERP customisation |
Is this the right fit
Built for you if
- You run an ERP (NetSuite, Business Central, SAP, MYOB Advanced or Cin7) alongside Shopify
- You're on Shopify Plus B2B, or moving to it, with a growing base of trade accounts
- Your team maintains pricing or stock in two systems, or re-keys orders daily
- You need account-level pricing, live inventory, credit terms and invoices in one place
Not the right fit if
- You're pure B2C with no wholesale side to connect
- You have no ERP yet, only spreadsheets, start with B2B development first
- You want a one-off CSV import rather than an ongoing, monitored sync
- You're on a platform other than Shopify, we're Shopify-only
What an ERP integration covers
Scoped after a systems audit. Every integration is monitored, logged and built to recover cleanly when an API has a bad day.
What's included
- Two-way sync of accounts, pricing, stock, orders and invoices
- Contract and volume pricing mapped to Shopify B2B catalogues
- Live inventory across multiple locations and warehouses
- Orders pushed to the ERP with account, tax and terms intact
Technical deliverables
- Middleware or direct API integration with queueing and retries
- Field mapping and a transformation layer between both data models
- Error logging, alerting and a reconciliation dashboard
- Idempotent syncs so nothing double-posts or duplicates
Systems & integrations
- NetSuite, Business Central, SAP, MYOB Advanced, Cin7
- Shopify B2B and Plus, Flow, Functions, company profiles
- iPaaS (Celigo, Alumio) or a purpose-built microservice
- 3PL, tax and payment gateways where the flow needs them
How we deliver it
A typical single-system integration runs 6–10 weeks. Larger multi-system work is staged so you see value early.
Discovery & systems audit
We map every entity, field and edge case across Shopify and your ERP, and agree what syncs which way. Week 1.
Integration design
Field mapping, sync direction, real-time vs batch, and failure handling, signed off before a line of code. Week 1–2.
Build & middleware
We build the integration, transformation layer and logging in a sandbox against your ERP test environment. Week 2–5.
Sandbox sync & UAT
Your team places real test orders and checks prices, stock and invoices end to end. Week 5–7.
Reconciliation & edge cases
We match ERP and Shopify records, harden retries and cover the awkward cases before go-live. Week 7–8.
Go-live & monitoring
Phased cutover with live monitoring, alerting and a 30-day warranty window. Week 8+.
Controls before go-live
An integration is only as good as its worst day. We test for those.
- Idempotency verified, no duplicate orders or invoices on retry
- Failure and retry paths tested against timeouts and bad payloads
- API rate limits respected on both Shopify and the ERP
- Reconciliation confirms ERP and Shopify records match
- Documented rollback plan and a phased cutover
- WCAG 2.1 AA on any buyer-facing account UI
Investment
Bands are typical AUD ranges, scoped after discovery. What moves the number is how many systems and entities sync, and whether it's real-time.
Single-system sync
One ERP, core entities, accounts, stock and pricing
Full B2B integration
Orders, invoices, multi-warehouse and real-time sync
Enterprise / iPaaS
Multi-system, high volume, with an ongoing SLA
