What if…
A client pays by check instead?
Record it in QuickBooks as usual. Krakzilla sees the invoice is paid and stops the reminders.
I change or void an invoice in QuickBooks?
Krakzilla reads the invoice again from QuickBooks before every email and every payment, so clients always see the current amount, and a voided invoice is never chased.
An email bounces?
The invoice is flagged on your dashboard and its reminders wait. Fix the address in Krakzilla and it's updated in QuickBooks too.
A client disputes or refunds a payment?
It's flagged on your dashboard and the payment's page, so you can sort it out with the client and record it in QuickBooks.
I stop using Krakzilla?
Disconnect anytime. Krakzilla stops at once and deletes its copy of your QuickBooks data after 30 days. Your QuickBooks records stay as they are.
