Office supply wholesale suppliers help schools, offices, and small businesses buy pens, paper, and other everyday items. They sell in bulk. Bulk orders cost much less than single items from a regular store. Buying wholesale can save a business real money over a year. This list covers ten real, currently operating office and business supply wholesalers in the United States. Each one made the list for a good reason. They all have a solid track record of selling office products in bulk to dealers, schools, or businesses.
What to Look for in Office Supply Wholesale Suppliers
Not every supplier fits every business. Check a few basic things before you place a big order. Look at the minimum order size. Check the shipping regions too. Find out if they sell directly to businesses, or only through dealers. A good supplier should also be easy to reach if something goes wrong with your order.
Buyer Tip: Ask any new supplier for their price sheet and order minimum before you commit. Many wholesalers offer lower prices once you buy by the case, not the single item.
A wholesale distributor can also beat a retail store in other ways. Stock tends to stay steady, and pricing often gets better over time. We cover more of these perks in our guide on the benefits of working with a wholesale distributor.

Buyer’s Checklist Before You Order
Use this quick checklist when you are vetting a wholesale office supplier for your business.
| What to Check | Why It Matters |
|---|---|
| Minimum order size | Some wholesalers require a case or dollar minimum before they’ll ship |
| Shipping regions | Some suppliers only deliver in certain states or regions |
| Dealer-only vs. direct sales | Some suppliers sell only to registered dealers, not to the public |
| Return policy | Bulk orders are expensive to return, so know the rules first |
| Reorder process | A simple reorder system saves time on future purchases |
Independent dealers sometimes join buying groups. One example is American Office Products Distributors (AOPD). Groups like this help dealers get better wholesale pricing. It’s worth asking a supplier if they belong to a group like this, since it can affect price.
