Can I create bulk Sales Receipts for 700+ members to credit EFT payments of their annual membership subscription? If so, how?

I appreciate you reaching out to the Community, @jpjmflanagan.

Let me help share some information about bulk sales receipts.

Currently, we don't have this feature in QuickBooks Online. There may be a 3rd party app available for this. You can check this out through this link: QuickBooks Apps.

If you have other questions in QuickBooks Online, please don't hesitate to leave me a message below. I'll be around to help.
