Two-way inventory sync, order push, shipment write-back. Fishbowl, NetSuite, QuickBooks, custom ERPs. For businesses where CS is spending 30%+ of their time moving data between systems that should already talk.
The problem this solves
Your WooCommerce site takes orders. Your ERP (Fishbowl, NetSuite, QuickBooks, SAP Business One, or something more custom) tracks inventory, pricing, customers, and shipments. In between: a spreadsheet, or a person, or a Zapier chain held together with hope.
Symptoms:
- Customer service is re-keying more than 20% of orders
- Inventory counts drift between systems within a week
- You’ve lost an account to a stockout that shouldn’t have happened
- The previous integration attempt is now silently broken and nobody wants to touch it
- You’re quoting 48-hour ship times but actually shipping in 4-7 days because of the data lag
What gets built
A custom integration layer. Usually:
- Two-way inventory sync (ERP is source of truth, WooCommerce reflects within minutes)
- Order push from WooCommerce to the ERP with customer matching and line-item mapping
- Shipment and tracking write-back from ERP to WooCommerce order
- Price and product catalog sync when they change in the ERP
- Exception handling (what happens when a customer match fails, when stock goes negative, when an ERP is down)
- Alerting and an operations dashboard for the exceptions
ERPs this has been done against
Fishbowl, NetSuite, QuickBooks Enterprise, SAP Business One, Microsoft Dynamics GP, Acumatica, and several custom in-house systems built on SQL Server or MySQL. The approach is portable; the specific adapter is per-ERP.
Common objections
“We already tried this and it failed.” Fair. Most failures come from treating the integration as a one-time project instead of a maintained system. Versions change. Edge cases emerge. This work comes with ongoing maintenance built in.
“Can’t Zapier do this?” Zapier is excellent for small volumes and simple workflows. It struggles at volume, at transactional integrity (partial failures are messy), and at the custom business logic most real ERPs need.
“We’re on Shopify, not WooCommerce.” Similar work, different API surface. Ask.
Engagement shape
Scoped project for the initial integration (typically $12K-$45K depending on complexity), then a maintenance retainer ($1K-$3K/month) for ongoing version handling, edge case resolution, and extensions as the business grows.

Common questions
- How long does a WooCommerce to Fishbowl integration take to build?
- Typical first-phase delivery is 4-8 weeks from kickoff, depending on catalog size and the number of WooCommerce extensions involved. A basic inventory and order sync can ship in 2-3 weeks.
- What does WooCommerce ERP integration cost?
- Initial builds usually run $12,000 to $45,000 as a scoped project. Ongoing maintenance runs $1,000 to $3,000 per month.
- Can this work if our ERP is a custom in-house system?
- Yes, as long as it has an accessible API or direct database access. The integration layer is adapter-based, so swapping the specific ERP client is the main lift.
- What happens when the integration breaks?
- Alerting fires immediately (email, SMS, or Slack depending on preference). Failed transactions queue for replay rather than being lost. An operations dashboard shows what is stuck and why.
- Do you work with Shopify or BigCommerce too?
- Yes. The approach is portable across ecommerce platforms.
- Will this slow down our site?
- No. The integration runs out-of-band on the server, not inside the page request. Customers will not see a difference.
- Can you rescue an integration that was built by someone else?
- Yes. About 40% of integration work starts as a rescue of a prior build.
