How do businesses keep track of invoices without creating extra work?

Hi everyone,

I was talking with a friend who runs a small business, and one of the biggest challenges they mentioned wasn't getting new clients—it was keeping track of invoices, due dates, and payment records.
As the business has grown, managing everything manually has become more difficult. It made me wonder how other business owners handle this. Do you still rely on spreadsheets, or have you switched to invoice management solutions that automate reminders, approvals, and payment tracking?
I'm not looking for recommendations from vendors. I'm more interested in hearing real experiences from people who have dealt with this challenge.
For those who have made the switch:
What was the biggest improvement you noticed?
Did it save time or reduce invoicing mistakes?
Are there any features you now consider essential?
I'd appreciate hearing your experiences and any practical advice you can share. Thanks!
