Context
Connecting SeniorERP to eCommerce requires bidirectional synchronization: SeniorERP stocks + prices → eCommerce, eCommerce orders → SeniorERP.
Option 1 — Standard SeniorERP Connectors
Senior Software provides pre-built connectors for major platforms.
SeniorERP stock sync → eCommerce (5-15 min)
Daily price sync
Order pull → SeniorERP
Invoice push → eCommerce
Cost: €4-8k setup + €1.5k/year maintenance per platform.
Limitations
1. Per-platform sync, not cross-channel.
2. Single warehouse default — multi-warehouse requires customization.
3. Limited complex pricing & promotions (bundles, BOGO, loyalty).
4. Basic returns/refunds workflow.
5. Missing Marketplaces (eMAG, Allegro, Amazon).
6. Real-time stock lag — 5-15 min sync = risk of overselling at high velocity.
Option 2 — Azuvio Smart Layer OMS
Azuvio OMS centralizes:
Real-time cross-channel stock (Shopify + Magento + WooCommerce + eMAG + retail + marketplaces)
Intelligent inventory allocation per channel
Cross-channel pricing & promotions with an advanced rules engine
Intelligent order routing (nearest warehouse, optimal shipping cost)
RMA / returns / refunds workflow
Native Marketplace connectors
SeniorERP Integration:
SeniorERP = master for items, base prices, physical inventory
OMS = master for cross-channel orders, allocation, fulfillment
Finalized orders → SeniorERP for invoicing + accounting
Cost Comparison (3 channels, 1,000 orders/day)
SeniorERP Connectors: 3 × €6k + €4.5k/year + €15k custom marketplaces = 5-year TCO ~€55k + revenue lost to overselling
Smart Layer OMS: ~€12k setup + €18k/year = 5-year TCO ~€102k, but errors -90%, overselling ~0%, marketplaces included
The Difference: OMS is ~€47k/5 years more expensive, but eliminates 2-5% eCommerce revenue loss — for a €5M/year turnover = €100-250k/year recovered.
When to choose which
Standard Connectors: Single channel, <300 orders/day, conservative budget.
Smart Layer OMS: 2+ channels, marketplaces, 500+ orders/day, complex promotions, zero tolerance for overselling.
The Doctrine
SeniorERP remains the master for invoicing + accounting + physical stock. The OMS acts as the master for cross-channel orchestration.
Conclusion
For small-scale single-channel operations, standard connectors are sufficient. At scale, SeniorERP + Smart Layer OMS eliminates 80% of sync errors.
