Is there a way of getting your invoices e signedvia the app ?

 It's good to see you here in the Community, @noel11.

Yes, you can let your customer sign an invoice with your QuickBooks Online mobile app. Let me guide you through the process.

These steps will work for both IOS and Android:

1. Click Menu, then select Invoice.
2. Choose an existing transaction or create a new one.
3. Enter the necessary information and click Save.
4. Select Get Signature. Then, have your customer sign with their finger.
5. Click Done.
