How do you make historical billing data actually readable in UI?

I was checking out this site for something unrelated — just doing a quick fesco 2024 bill check — and it got me thinking: why do so many billing history pages feel like spreadsheets from 2004?

There’s a ton of opportunity to clean up how historical utility data is displayed. Stuff like monthly charges, payment status, due dates — it’s all super useful, but the design is usually overwhelming or just plain dated.

Has anyone here worked on visualizing that kind of timeline-based data? I'd love to see how others are approaching it — especially for mobile, where scrolling endless tables is a nightmare.

Appreciate any insights or examples!
