The EDI Challenge for NextUp Users
If you supply Carrefour, Metro, Auchan, Kaufland, Selgros, Dedeman, Mega Image, Lidl, or eMAG Marketplace, you are contractually required to exchange electronic documents (EDI): purchase orders (ORDERS), dispatch advice (DESADV), invoices (INVOIC), and receiving advice (RECADV).
NextUp ERP features a modern REST API, but lacks pre-built EDI connectors for all these retailers. You must choose one of three options.
Option 1: Custom Development per Retailer
Mechanism: A developer builds a dedicated connector per retailer (parsing EDIFACT/XML, mapping NextUp fields via API, connecting to the retailer's portal).
Cost: €5,000-€15,000 per retailer (initial) + €1,500-€3,500 annual maintenance per retailer.
For 5 retailers: ~€50,000 initial + €12,500/year (~€115,000 over 5 years).
Challenges:
Every retailer schema change = redevelopment
Fragmented troubleshooting (5 separate systems)
Lack of centralized visibility
Dependency on a specific developer
Option 2: Third-Party EDI Platforms
Providers: EDIconnect (Soft Net), Comarch EDI, GS1 Romania.
Average cost: €28,000-€73,000/year for 5-7 retailers.
Pros: Centralized dashboard, maintenance included.
Cons:
Prohibitively high cost for mid-market companies
Integration with NextUp is still custom (file export/import or API)
Vendor lock-in
Option 3: Azuvio EDIconnect Smart Layer
Native Azuvio module with pre-built connectors for the top 15 retailers in RO + EU.
Cost: €3,600-€7,200/year for 5-7 retailers.
Pros:
Native integration with NextUp via REST API (automatic mapping)
Pre-dispatch validation (prevents chargebacks)
Centralized dashboard
Schema updates and maintenance included
Automatic retries
5-Year Cost Comparison (5 Retailers)
| Option | Year 1 | Year 2-5 /year | Total 5 Years |
|---------|------|------------|-------------|
| Custom dev | €50,000 | €12,500 | €100,000 |
| Third-party platform | €45,000 | €45,000 | €225,000 |
| Azuvio Smart Layer | €6,000 | €5,500 | €28,000 |
Typical ROI for EDI Smart Layer
Real-world scenario: Mid-market distributor, 6 retailers, 8,500 invoices/year.
Current costs (manual + Excel):
Retailer chargebacks (manual EDI errors): ~€32,000/year
Manual processing time (0.7 FTE): ~€16,000/year
Sporadic maintenance: ~€7,000/year
Total: ~€55,000/year
With Smart Layer:
Azuvio cost: ~€6,500/year
Reduced chargebacks (-95%): ~€1,600/year
Manual time eliminated: €0
Total: ~€8,100/year
Net savings: ~€47,000/year. ROI: 8x.
Conclusion
For a NextUp user supplying major retailers, the EDIconnect Smart Layer is by far the best cost/benefit option. NextUp remains the system of record (invoices, inventory, accounting); Azuvio manages the EDI layer without disrupting the ERP.
