QuickBooks is the accounting standard for US small businesses. Influx Theory is not trying to be QuickBooks — it's trying to be the invoicing app you actually enjoy using. The two work well together: send invoices in Influx Theory, export to QuickBooks at tax time.
If you need double-entry accounting, payroll, and a CPA-friendly chart of accounts, you need QuickBooks. If you just need invoices that don't feel like 2008, you need Influx Theory.
