So I'm an electrical contractor and I needed updated material price list I found a company called accupricelists.com they will have documents that you can import into QuickBooks with the top 1200 items electricians use from what I was told they are beta testing auto sync with QuickBooks Online... i hope soon because qb only allow 200 items to import at a time. This website's awesome because I can custom the markup and tax tailored to my business. Supposedly they're going to have drywall Lumber and Plumbing soon.
