Hi there magicscapelandsc,
It's important for any business owner to get invoices out to their clients to bill them for their services. QuickBooks-Self-Employed is a great tool to help you create and send these invoices. I can provide some assistance with this.
When it comes to creating invoices, there isn't a limit to how many invoices can be created in the software. There isn't any limit to how many invoices can be sent from the software either.
If you have any other questions, feel free to reach out here.
