ERP for eCommerce: When Your Store Needs an ERP
Why growing eCommerce brands need an ERP: multi-channel stock, order routing, returns, marketplace fees, accounting and how to connect Shopify, WooCommerce and Amazon.
Most online brands start with a store platform and a spreadsheet. Growth adds channels, warehouses and returns, and the spreadsheet breaks. That is when an ERP pays off.
Signs your store needs an ERP
- You sell on your site, Amazon and wholesale, and stock is updated by hand
- You oversell during promotions
- Returns are tracked in email
- Payouts from Shopify, Amazon and PayPal never match the books
- Purchasing is based on guesswork
Multi-channel inventory
The ERP becomes the single source of truth for stock. Each channel receives available quantities from it, so one sale anywhere reduces stock everywhere.
Order routing and fulfilment
Orders from every channel flow into the ERP and are routed to the right warehouse or 3PL, with picking, packing and shipping labels. See our 3PL industry page.
Returns
A returns process with reasons, inspection and restocking or write-off. Refunds are linked to the original order and payment.
Marketplace and payment fees
Each channel pays out net of fees. The ERP should post fees to the right accounts and reconcile payouts to the bank. See the Odoo Amazon integration guide.
Purchasing
Replenishment based on sales velocity, lead times and seasonality, with landed costs for imported goods.
Accounting
Sales, tax, cost of goods sold and fees posted automatically. Month-end becomes a review, not a rebuild.
Integration options
Or use the Odoo website and eCommerce store built into the ERP.
Where to start
Start with inventory, orders and accounting for your main channel. Add marketplaces and wholesale once stock is accurate.
See our eCommerce industry page or our free eCommerce ERP setup.
Frequently asked questions
When does an online store need an ERP?
Usually when you sell on more than one channel, hold stock in several places, or spend hours each week reconciling orders, stock and payouts.
Can an ERP replace Shopify?
Some ERPs, like Odoo, include an online store. Many brands keep Shopify for the storefront and use the ERP behind it.
