I want to share some insights about why Qwilr doesn't work even if it's integrated into QuickBooks Online (QBO) and point you to the best support to help with your concern, @royann.
QuickBooks supports multiple integrations with different external applications and depends on the data provided. Since you've integrated QBO directly from Qwilr and it doesn't work with the program, this can be due to the mapping and setup issues. With this, I recommend contacting your third-party provider for assistance. They're capable of checking your account settings and ensuring it integrates successfully.
Please visit their Help Center website for the contact details and talk with an expert.
Moreover, QuickBooks has an app store that you could use to search and connect applications that suit your business. It also shows some compatible providers.
In addition, once you create an estimate, you'll have to convert it into an invoice and bill it to your customer.
This points you in the right direction. If you require additional assistance or have other concerns with managing your integrations in QuickBooks Online, we'll be here to lend you a hand.
