I tend to disagree with that as a blanket statement.
There are a lot of companies that use other software to generate pricing for quotes and invoices because typical accounting software cannot handle the complexity of pricing items in some industries.
These companies still need to use an accounting software because most CPA’s want the information sent to them the way an accounting software formats things.
Being able to import basic invoice data is essential for these types of companies.Customer name, order date, line item description, line item total, tax, invoice total, payments, balance and a reference number.
You can import to Quick Books but it is a pain. I was hoping to point people to Manager but if there is no way to import basic invoice information then Manager is not an option.
