Hi there, howardjennings.

I've already updated and added a few things provided above for the price update to flow into the existing template. It has to sync first with the current price in products and services.

To do that, Open your template and you'll need to toggle the item from your product and services field. Then, go back to selecting the item so the amount will update to the current price. This means your template has synced with your products and services.

To be able to update the price for your template all the time, you have to check the box under Update price in recurring templates from Product/Service information.

If you'd miss checking the box, you won't have that option the next time you update the price. This mean, you'd need to go back to your template and sync with the current price in products and services.

I'll provide a screenshot for more details.

For further concerns, please feel free to post again here in Community.  Have a wonderful week ahead.​
