Unified Shopify, Manhattan WMS, and ERPNext for scalable e-commerce fulfillment
A fast-growing golf e-commerce brand running Shopify for storefront and a 3PL on Manhattan WMS — with ERPNext as the operational and financial backbone tying them together.
At a glance
The engagement, in brief
The challenge
Where they started
Alphard Golf sells direct-to-consumer through Shopify and fulfils through a third-party logistics provider running Manhattan Active WMS. Each system held a slice of the truth — and none of them agreed.
- Inventory lived in three places (Shopify, the 3PL’s WMS, and finance spreadsheets) and constantly drifted out of sync
- Orders were re-keyed by hand between Shopify and the 3PL, introducing delays and fulfilment errors
- No unified financial view — revenue, COGS, and stock valuation were reconciled manually after the fact
- Scaling SKUs and order volume meant the manual glue between systems was about to snap
What we built
How we solved it
ERPNext as the system of record
ERPNext became the single source of truth for items, pricing, inventory valuation, and accounting — with Shopify and the WMS treated as connected endpoints, not separate databases.
Shopify ↔ ERPNext integration
- Orders flow automatically from Shopify into ERPNext as Sales Orders
- Product, pricing, and stock availability stay synchronized both ways
- Customer and payment data captured against each order for clean reporting
Manhattan WMS ↔ ERPNext integration
- Sales Orders dispatched to the 3PL’s WMS for pick, pack, and ship
- Shipment confirmations and tracking flow back into ERPNext automatically
- Real-time stock positions reconciled against the warehouse on every movement
Unified financials
With orders, fulfilment, and inventory all landing in ERPNext, revenue recognition, COGS, and stock valuation became automatic — no month-end spreadsheet reconciliation.
The results
What changed
- Real-time inventory accuracy across Shopify, the WMS, and finance
- Orders flow end-to-end with no manual re-keying
- A single, trustworthy financial view of the e-commerce operation
- A fulfilment architecture that scales with SKU and order growth
