The QuickBooks Shipping Manager allows you to ship packages within the software using your favorite shipping services! Intuit did the haggling for you and worked out a deal with the USPS.
Save 15% on Priority Mail and 21% on Express Mail if you print your postage through QuickBooks.
You also get a FREE limited account with Stamps.com, a website that provides postage on demand.
