It's a pleasure to have you in the Community today, @bestcarpetsteamb. I've got your back, and let's work this out so you can send invoices in your QuickBooks Online (QBO) mobile app.
A possible reason you're unable to send your invoices using the app version of QBO is that the app has accumulated a lot of caches or data, causing the operation to slow down. To get through this, you'll clear those data to refresh the application and avoid experiencing any issues. I'll input the steps below so you can proceed.
For Android users, here's how:
- In your phone, go to Settings.
- Select the QuickBooks Online application.
- Click the Refresh Data, and then choose Yes.
For iOS users, these are the steps:
- In your phone, go to Settings.
- Click on General, and then choose iPhone Storage.
- To free up the storage without deleting the documents and data for the app, select Offload App.
Additionally, here's an article to help you manage invoice payments in QBO mobile app: Receive an invoice payment using the QuickBooks Online mobile app.
