Hi @Sherbert99,
As I know, you can create a liability account. Go to Settings --> Chart of Accounts --> New, and create a new account. Set the account type as "Other Current Liabilities" and name it something like "Funds Held for Customer" or "Customer domain sales."
Then record the deposit. When the $3,000 hits your bank account, categorize the deposit under the "Funds held for customer" liability account. This ensures it’s tracked as money you owe to your customer, not as income.
When you write the $3,000 check to the customer, categorize the check to the same "Funds held for customer" liability account. This will reduce the liability and show that the money was passed through without impacting your income.
I think it should help
