Those out in the eBay world who haven’t used it find the service to be a life-changing experience. Because you don’t need to use additional software or sign up with an additional service, shipping with eBay is a convenient system for those who don’t have to ship many packages each week.
eBay shipping services work great when you’re just starting out in your business — but after you get rolling, you need a mailing service that includes recordkeeping, such as Endicia or Stamps.com. The issue connected with using eBay for shipping is important: When you process your shipping (UPS or USPS), the shipping amount is deducted from your PayPal (sales revenue) balance.
This can cause a bookkeeping nightmare when you’re selling on eBay in earnest. A best practice for any business is to keep all expenses separate in the bookkeeping process.
