Best billing software for businesses when invoicing becomes too tedious

This might sound oddly specific, but invoicing has become the thing I procrastinate on the most. It's not because it’s complicated but because it always seems to take longer than I expect.

For example, and this one happens to me a lot: the numbers look right but then something’s off. Sometimes a client asks for a tweak or a payment comes in late and I forget to mark it. By the end of the month, I’m double-checking things I know I already checked. I’ve been nursing the idea of switching tools, but real experiences are harder to find. Most of the time I only see polished comparison posts.

What would you recommend? Would love to hear your experiences too when you started using billing software.
