Fashion ecommerce has data challenges that standard integrations don’t handle well: thousands of variant SKUs (size × colour × material), return rates of 30–50%, seasonal collection drops, and the need to keep a tight loop between webshop stock, warehouse, and ERP.
This guide covers how Nordic fashion brands connect Shopify or WooCommerce with their ERP and what to configure for the fashion-specific flows.
The fashion-specific data challenges
Size matrices — a single product in fashion typically has 10–20 variants. Each size/colour combination is a separate inventory line in both the webshop and the ERP. The integration needs to sync at variant level, not just product level, otherwise stock counts are meaningless.
High return rates — fashion returns average 30–50%. Every return needs to create a credit note in the ERP linked to the original invoice, update inventory, and trigger a warehouse process. Handling this manually at scale is not feasible.
Seasonal collections — fashion brands drop new collections on a schedule. Pre-orders, campaign pricing, and seasonal article setup need to flow correctly between the webshop and ERP before and during launch.
B2B alongside D2C — many fashion brands sell both D2C online and wholesale to retailers. B2B orders often come through the same or a connected platform, and need to be routed correctly in the ERP with the right customer records and pricing.
What syncs between the webshop and ERP
- Orders — each order creates an invoice in the ERP with the correct variant-level product data, sales account, and VAT code
- Returns — refunds create credit notes linked to the original invoice and update inventory at variant level
- Stock — inventory syncs at variant level in near real-time from the ERP (or WMS) to the webshop
- Articles — new season products and variant structures can be managed from the ERP and pushed to the webshop
- Payouts — Klarna, Stripe, and Adyen payouts are reconciled against invoices automatically
Which ERP for a Nordic fashion brand?
For smaller Swedish fashion brands, Fortnox works well — simple setup, good Klarna integration, and broad accountant support. Mid-sized brands with international sales or multiple entities typically use Visma.net or Business Central. Business Central by Trimit adds fashion-specific features like size/colour matrix handling natively. See the ERP comparison guide.
Setup
Connecting Shopify or WooCommerce to a fashion ERP setup takes about 15 minutes for the technical connection. Configuration time depends on the complexity of your variant structure, OSS VAT mapping for EU sales, and return flow setup.
