I looked into accounting software. This posting set my mind:

Shameless C&P:

If you do not use Quickbooks:

* Your bank will hate you.

* Your investors will hate you.

* Your payroll system won't work.

* Your tax systems won't work.

* Your accountant won't work.

* Grants are even off the table in some cases.

* Some places won't audit without Quickbooks.
