Hey @RocketWMGmbH
Current system audit
First document everything in your existing setup:
Products & SKU structure
Inventory logic
POS workflows (sales, returns, exchanges)
Online order flow
Store transfers between branches
Accounting / ERP exports
Customer data handling
Understand exactly what must be replicated in Shopify.
- Define system ownership
Decide: Shopify becomes the MAIN system for:
Products
Inventory
Orders
POS (stores + online unified)
ERP/accounting system handles ONLY:
accounting
invoices
tax reporting
Avoid dual inventory systems.
- Clean & prepare data before migration
Before moving anything:
Remove duplicate SKUs
Standardize barcodes
Fix incorrect inventory counts
Clean product variants
Organize collections/categories
Bad data = biggest migration failure cause.
- Set up Shopify foundation
In Shopify:
Create store structure
Configure taxes (Austria/Germany rules if needed)
Set shipping zones
Set payment providers
Configure basic policies (returns, shipping, etc.)
5) Configure multi-location inventory
Set up:
Store 1 location
Store 2 location
Store 3 location
Warehouse if applicable
Then define: stock per location
inventory rules
fulfillment priority
transfer process between stores
- Set up Shopify POS system
Install and configure Shopify POS:
connect all store locations
assign staff roles
configure permissions
connect payment terminals
set receipt printers/barcode scanners
- Pilot store testing
Do not migrate everything at once.
Start with 1 store:
Test:
selling in POS
returns/exchanges
inventory sync
online order sync
barcode scanning
payments
Fix issues here before scaling.
- Integrate accounting / ERP system
Connect:
invoice system
accounting export (e.g., DATEV if needed)
tax reporting
payment reconciliation
Ensure compliance before going live.
- Run parallel system test
Before full switch:
Run both systems briefly:
old POS system
Shopify POS
Compare:
inventory accuracy
sales consistency
order syncing
10) Go live store by store
Rollout order:
Pilot store
Store 2
Store 3
Avoid all at once migration.
- Train staff
Train employees on:
POS usage
returns/exchanges
inventory checks
transfers between stores
online order handling
- Post-launch optimization
After migration:
install Shopify Flow (automation)
set low stock alerts
automate tagging/workflows
optimize reporting
improve fulfillment logic
I hope It’s help you
Thank You…!
