I would like to sync the data (just attached receipts and attachments to all my transactions ) of my Tide Business Account with the data on QuickBooks.

Good day, @userpusztavarien.

Thank you for sharing your concern with us. 

Are you using the Tide app to manage your mobile business bank account from your phone? If so, the option to sink its data such as receipts and attachments into QuickBooks is unavailable. 

However, you can manually attach them to your transactions in QuickBooks Online. Let me show you how:

1. Open your sales or expense transaction.
2. At the bottom left of the page, select Attachments.
3. Browse and select the file you want to attach, then select Open.

To review all of your uploaded attachments, you can follow these steps:

1. Select Settings ⚙️.
2. Under Lists, choose All Lists.
3. Click Attachments.

Additionally, here's how you will know what transactions you can add these attachments: What transactions can keep attachments?

I'm always here to help if you have any other concerns or questions. Just tag my name in the comment section and I'll get back to you as soon as I can. Have a great weekend.
