Hi there, Lisa. Right now, the manual process is the only way to get your client's data into the system. There are just two options in QBO: you can either connect the bank or manually upload the files.
The advantage of manual uploading is that you catch errors immediately, so you don't have to fix mistakes later. However, since this takes up a lot of your time, you could have your client connect their bank directly. You might also consider using a third-party app to help speed things up.
You can visit this link for more details on how to find apps: Install and use apps.
Let us know if you have further concerns.
