# How to estimate COD fees and profit before going live

**COD Simulator** projects the total fees a cash-on-delivery confirmation partner will charge on an order — so you can check a product is profitable before you run ads on it.

## Steps

1. Open **Apps → COD Simulator**.
2. For each partner accordion (COD Partner, COD Network, Prime COD, Lofty Service), enter its known fees: Cost per Lead, Confirmation Cost, Cost per Delivered, Subscription Fees, COD Fees (%), Exchange Fees (%), and per-country Fees / Confirmation Rate / Delivery Rate, then click **Save Settings** for that provider.
3. Click **Simulate** to open the simulation form.
4. Select one or more **Services** (partners) and **Countries**, set **Quantity**, **Advertising Cost**, **Selling Price**, and the **Product Cost** for each selected service.
5. Click **Run Simulation**. A results table compares every service/country combination side by side, with the best and worst values for each row (profit %, advertising cost, etc.) color-coded green/red.
6. Click **Start Over** to change your inputs and run another scenario.

## Common problems

- A cell shows "Not Supported" → that provider has no shipping row saved for that country yet; go back and fill in its shipping row under that provider's accordion, or pick a different country.
- "Run Simulation" stays disabled → you must select at least one service and at least one country first.
- Quantity is rejected → Quantity must be a whole number of 1 or more.
- No merchant support tickets were found specifically about COD Simulator; the steps above come directly from the app's interface.
