Leaving Zoho for MHelpdesk......

Leaving Zoho for MHelpdesk......

I'm looking to move to MHelpDesk but they have no option for me to import my invoices. Is there a cheaper plan I can switch to, like the free plan, just to let me keep my records here for a little while, or when I switch to the free plan will it delete any of my records/customers/invoices?
