Once the initial set-up process linking accounts is complete, check writing activities can be done solely within QuickBooks Online. Or you can continue to use eChecks at times when you want to take advantage of eCheck functionality ‐ like separating the roles of check creator from check signors. You choose what works best for your business.
There are also some functions – performed by Administrative users – that will occasionally need to be performed within the eChecks account. Examples of these transactions are: re-ordering eChecks, voiding eCheck payments, etc.
