Adding additional costs to a fixed assess

I am building a new warehouse. I added it to fixed costs. However I will be adding additional costs as I go. But payments/receipts won’t let me assign new receipts to this fixed item. How do you add additional costs to a fixed item?

You are mistaken. Payments can be allocated to Fixed assets and the specific asset’s subaccount. See https://www.manager.io/guides/9106. Perhaps you created an account for this asset yourself instead of entering it as a fixed asset in the Fixed Assets tab?

Thanks!
