Yes. Also wondering about the ROI. What do you gain by this?

For transactions: you spot fraud, mischarges or subs to cancel. Really a watchdog service would be good here. High effort, low return. IMO. (And a bit of tracking around reimbursements)

For savings: helps you keep an eye on where you’re at by forcing you to reconcile.

It’s totally worth it for a low value of invested time. But, it’s not going to be low effort.
