Is it possible to text an invoice to a client with a link to pay?

No, only email. In fact most texting services do not allow attachment of pdf files. You can print an invoice and take a picture of it to send and if you could ascertain the https link for paying that particular invoice you could include it in the text.  Usually if one can receive texts they can also receive email on the same device

Hi there, lmmcgill.

Currently, we're unable to directly send an invoice via text message. Though, you can send an invoice link to your customers over SMS so they can view and pay their invoice using the Save and share link feature. I'll show you how to do it:

1. Click the + New button, then select  Invoice.
2. From the Customer drop-down menu, select a customer. 
3. Enter the necessary information.
4. When you're done, select Save and share link from the drop-down arrow.
5. Click the Copy link button, then paste and send it via SMS or any other messaging platform (see below).

Altertnatively, you can visit our QuickBooks App Center to find a third-party application that can directly send invoices to your customers using text messages or SMS.

With QuickBooks Online, you can also personalize the invoices so your customers will recognize your brand.

If I can be of any additional assistance, please don't hesitate to insert a comment below. Stay safe and healthy.

You need a messaging app and a connector to QBO to do so.

Yes! You can use SnapDesk (found on the Quickbooks app store) to automate invoice collection via text message.

They sync your Quickbooks invoice links over and let you send the link via text message in a customized message at chosen intervals.

Hi there!

Yes there is! You can use SnapDesk (I found it on the quickbooks online app store) to send invoices via text message.

You can send individual invoices as one off collections or send them out in bulk on defined schedules until the invoice gets paid.

I've linked more information below if you're interested! So far I've loved their customer service so I'd suggest giving them a call at the very least
