# Fixing "Payment method Cash is not an invoicing account"

HTML version: [Fixing "Payment method Cash is not an invoicing account"](https://support.gladstonesoftware.cloud/gooperator/payment-method-cash-is-not-an-invoicing-account-error)

## Problem
Every attempt to create a block booking in Go Operator Centre Management fails with "Payment method Cash is not an invoicing account. Block bookings must be paid via an invoicing account".

## Root Cause
The **Invoicing** payment method isn't set as the default for hosts in Plus2. The error names Cash because Cash is the fallback default, so it looks like a product defect.

## Resolution

1. **Open Configuration in Plus2**
   - Select **Configuration** on the top menu.

2. **Open Financials**
   - Select **Financials**.

3. **Open Payment Methods**
   - Select **Payment Methods…**

4. **Open the Invoicing payment method**
   - Double-click the **Invoicing** payment method.

5. **Tick Default for Hosts**
   - Tick **Default for Hosts**.

## Notes

- The full error text is: *Payment method Cash is not an invoicing account. Block bookings must be paid via an invoicing account*.
- This has blocked whole UAT test phases until found. Check it during site set-up, before anyone tries to book.
