Hi there, accounting-jasse.

I'll provide information about connecting QuickBooks Online with Inflow.

QuickBooks Online connects with hundreds of different applications. However, connecting Inflow to the QuickBooks system is currently supported by QuickBooks US, Canada, UK, and AUS. With this, I'd suggest contacting the Inflow support team to check if their software can integrate with QBO international version.

I'm also adding different articles to further guide you in effectively managing your business using QBO: Help Articles. It contains topics about advanced accounting, banking, and payments.

Feel free to get back if you need additional assistance. I'm always here to help. Take care!
