The CIO/COO dilemma: the old ERP (Legacy) is secure and accounting-focused, but terrible to use and stalls operations. Replacing an ERP costs millions and takes years. The modern solution is the **"Two-Tier ERP"** strategy: keep legacy in the back and put an agile layer in front.

### **The agility layer**

Let SAP/Oracle handle balance sheets and taxes. Use a Low-Code platform to build screens that employees, clients, and vendors use. This agile layer talks to the legacy system but offers a modern, mobile experience.

### **Advantages of this strategy**

- **Low risk:** You don't touch the company's accounting core.
- **Lower cost:** Agile platform licenses are cheaper than ERP licenses.
- **Modern UX:** The employee uses a nice mobile app, not a grey desktop screen.
