Subscription / annuity transactions

I run a Software as a service company

We Bill the customers up front an annual amount for there subscription but need to account for the amount monthly.

Is there a way to enter a single invoice for the customer and then have the software spread the amount evenly over 12 months in the accounts?

At the moment we manage all the detail in excel and use journals each month to ensure the correct values are shown - this is far from ideal, prone to error and not sustainable

Thanks
