Do I have to change my ERP to add a WMS?

No. A WMS on top of your existing ERP (Smart Layer) connects via connectors: it receives orders from the ERP and sends stock movements back, with no migration.

How long does each approach take?

WMS on top of the ERP: 6-12 weeks with a pilot. Standalone WMS with full migration: 4-6 months. Payback is usually faster with the on-top-of-ERP model.

How does the WMS connect to e-Transport and invoicing?

A WMS on top of the ERP integrates with the rest of the Azuvio layer: it generates a UIT code at shipment and links delivery to invoicing and reconciliation.

Standalone WMS vs. WMS on top of your ERP: which to choose

When you need a WMS, you have two paths: a standalone system with full migration or a WMS that sits on top of your existing ERP (the Smart Layer model). The choice affects the project's time, risk and cost.

This guide compares the two approaches honestly, with the situations where each fits.

The decision criteria

Implementation speed
WMS on top of an existing ERP: 6-12 weeks, with a pilot on one zone. Standalone WMS with migration: 4-6 months. If you need warehouse control fast, the layer on top of the ERP wins.
Project risk
Full migration means disruption and data-loss risk. A WMS on top of the ERP doesn't touch the accounting base and reduces risk — orders come from the ERP, stock movements go back to the ERP.
Integration with operations
A WMS on top of the ERP connects naturally to the rest of the layer: e-Transport (UIT code at shipment), invoicing and reconciliation. An isolated standalone WMS needs separate integrations.
Total cost
Standalone may have deeper features, but migration and integration cost is high. On top of the ERP, cost is lower and payback faster for most warehouses.

When to choose each

WMS on top of the ERP (Smart Layer): most companies with an existing ERP that want fast control, without migration.

Standalone WMS: highly specialized operations, no suitable ERP or niche requirements only a dedicated system covers.
