Keep forgetting who didn't pay?

I originally thought invoice creation was the painful part for freelancers and small businesses.

Turns out the bigger issue was attention management:
people stop reopening spreadsheets once work gets busy.

That pushed me toward building a much lighter workflow:

• unpaid visibility

• overdue tracking

• simple dashboard
  instead of full accounting complexity.

Still validating whether this solves a real enough operational pain:
