Engagement

How we build ERP Implementations & Connectors

A repeatable four-phase engagement. Same rigor every time, scoped to the work in front of us.

Phase01
Week 1-2

Discover

We map the current state, surface constraints, and lock the scope before any code is written. You leave the phase with a written success definition.

  • Audit document
  • Success criteria
  • Risk register
Phase02
Week 2-3

Architect

We pick the stack, design the data model, and prove the riskiest path first. Architecture decisions are reviewed with your team before build starts.

  • Architecture doc
  • Stack decision record
  • Spike on riskiest path
Phase03
Week 3-10

Build

Iterative delivery in weekly increments. You see working software every Friday, can redirect priorities each Monday, and never wait six weeks for a demo.

  • Weekly demo cadence
  • Production-ready code
  • CI/CD + tests
Phase04
Week 10+

Operate

We ship with observability, hand off runbooks, and stay accountable post-launch. 30-day hypercare is included on every engagement.

  • Monitoring dashboards
  • Operational runbooks

The Back-Office Integration Problem

Growing e-commerce brands eventually hit the same wall: orders come in through Shopify, but fulfillment, inventory, and accounting live in a separate ERP. Without integration, someone is manually rekeying data between systems — introducing errors, adding latency, and consuming hours that could be spent on higher-value work.

We build the connectors that eliminate this wall. Bi-directional, reliable, observable integrations that keep your commerce and back-office systems in sync without manual intervention.

What We Connect

Shopify ↔ NetSuite

The most common integration we implement. Key data flows:

Shopify → NetSuite:

  • New orders create NetSuite sales orders
  • Customer records synchronized or created
  • Fulfillment events update order status
  • Returns and refunds create credit memos

NetSuite → Shopify:

  • Inventory levels updated from NetSuite warehouse data
  • Product information synchronized from NetSuite item records
  • Price list changes propagated to Shopify

Financial reconciliation:

  • Shopify payouts reconciled against NetSuite deposits
  • Transaction-level mapping for auditing
  • Automatic journal entries for payment processing fees

Shopify ↔ QuickBooks

For brands on QuickBooks (Online or Desktop):

  • Order → invoice automation
  • Customer record synchronization
  • Payment and refund reconciliation
  • Inventory level updates (QuickBooks Desktop)
  • Tax calculation and reporting exports

3PL and WMS Integrations

Many brands use third-party logistics providers with their own warehouse management systems. We integrate with:

  • ShipBob, Shipwire, Whiplash, and custom 3PLs
  • EDI-based trading partner integrations
  • Custom WMS systems via REST or SFTP

Architecture Principles

Event-Driven, Not Polling

We build integrations that react to events (webhooks, message queues) rather than polling on fixed intervals. Event-driven integrations are more responsive, more reliable, and put less load on all connected systems.

Queue-Based Reliability

All data flows through durable message queues. This means:

  • No data is lost if either system is temporarily unavailable
  • Processing is retried automatically on failure
  • High-volume periods don't overwhelm the receiving system

Idempotent Processing

Every integration is designed so that processing the same event twice produces the same result. This eliminates duplicate records when retries are necessary.

FAQ

Common questions

Everything you need to know before starting a project with us.

We implement near-real-time sync (sub-5 minute) for inventory levels, and webhook-based real-time sync for order events. Sync frequency is configurable based on your volume.

We implement queue-based architecture — orders are buffered and processed when the ERP recovers. Your Shopify store continues operating normally; the ERP processes retroactively with no data loss.

ERP implementation cost varies based on complexity — a standard NetSuite Shopify connector with order and inventory sync typically starts in the mid-five-figure range. Factors like custom field mapping, multi-location inventory, and financial reconciliation requirements influence the final scope and investment.

Off-the-shelf NetSuite Shopify connectors work for basic setups, but high-volume stores processing thousands of orders daily need custom-built integrations with queue-based architecture and idempotent processing. We build bespoke connectors that handle peak traffic without data loss or duplicate records — something generic middleware consistently fails at.

A typical ERP ecommerce sync project takes 8–14 weeks from architecture through production deployment, depending on the number of data flows and systems involved. We phase the rollout — starting with order sync, then inventory, then financials — so you see value before the full integration is live.

Yes. While NetSuite and QuickBooks are the most common, our ERP Shopify integration approach works with any system that exposes an API, supports file-based exports, or can connect via EDI. We've built connectors for custom ERPs, SAP Business One, and legacy systems using SFTP-based data exchange as a bridge.
