I’ve been using QuickBooks Pro (desktop version) for several years now with my (mobile) Locksmithing business. It has worked just fine. During the day as I drive from job to job I write up paper invoices and the customer usually pays me on the spot. Credit card or check and all is fine. Then in the evenings I enter that days invoices into QuickBooks on my desktop so sales and inventory, etc, are tracked electronically. So basically I’m DOUBLE entering everything! I would like to switch to some “online” method so I can use my phone to produce the invoice and deplete the inventory “live” and therefore I only have to enter each sale once. However, switching to QB online is $70 per month! What do you guys do? Is there a good system out there that is not so expensive? Thanks.
