Does anyone else have problem with QuicBooks not sending invoices? when i click save and send invoice everything seem to be fine except my clients don’t receive them

Well done sending the invoice links as a workaround to keep your clients updated, Rafal. I'll outline some of the possible reasons why your customers aren't receiving your emails and guide you on how to resolve the issue.

If you recently imported QuickBooks Desktop (QBDT) data into a QuickBooks Online (QBO) company, you need to reset your email address. Here's how:

1. Sign in to your QuickBooks Online account.
2. Go to Settings, then select Account and settings.
3. Select the Company menu, then click Edit in Contact info.
4. Review each email address and make changes as needed.
5. Click Save, then Done.

If the resolution above doesn't apply, I recommend asking your clients to check their junk mail and spam folders. If the email is still not found, clear and then re-enter your email address. Here's how:

1. Go to Settings, then select Account and settings.
2. Go to the Company section, then select Edit in Contact info.
3. Clear the Company email field and enter the desired address as is, even if it appears correct.
4. Click Save, then Done.
5. Send yourself a test transaction.
6. If you still don't receive the email, try using a different email address that has a different domain (for instance, if you were using a Gmail email address, try a Hotmail or Yahoo address instead).

If the issue persists, you can configure the server to accept QuickBooks Online mail host names and IP addresses. For the complete guide, please see this article: Troubleshoot if customers aren't receiving emails from QuickBooks Online.

Furthermore, once your customers pay your invoices, record those payments to balance your income accounts. For the step-by-step guide on how to do this, you can check out this article: Receive invoice payments in QuickBooks Online.
