Technically you could bunch up all payments to service providers under a "services" account, or just a "household expenses" account, or even a general "money gone" account.

However, I have often found that when I do that, inevitably someone asks, "so how much of our expenditures this year were for the internet connection?" and then it would have been really useful to have that ISP account.

But if you don't need it, don't have it.
