ProSource Wholesale: What to Know Before You Shop

By Constance Obi · Culture & Recreation Writer

What ProSource Is and How It Works

ProSource is a membership-based wholesale distributor that sells building materials, tools, and supplies primarily to contractors, builders, and trade professionals. Unlike retail stores where anyone can walk in and buy, ProSource requires a membership to shop there. The company operates warehouses across the United States, including locations in South Carolina, where members can purchase items at wholesale prices.

ProSource makes money by charging annual membership fees rather than marking up products heavily. This model means members typically pay less per item than they would at a traditional hardware or building supply store. The trade-off is that you need to buy a membership first, and you often need to buy in larger quantities than a casual homeowner might want.

The company focuses on serving the construction and trades industry—electricians, plumbers, HVAC contractors, framers, and general contractors make up the bulk of their customer base. However, ProSource also offers memberships to serious DIYers and small business owners who want access to wholesale pricing on materials they use regularly.

Key Takeaways

  • ProSource requires an annual membership fee to shop, and membership types vary depending on whether you are a licensed contractor, a business owner, or a DIY homeowner.
  • South Carolina has multiple ProSource locations, and you can find the nearest warehouse by visiting their website or calling to confirm hours and product availability.
  • Membership pricing and benefits differ by location and membership tier, so it pays to ask about current rates and what each tier includes before joining.
  • ProSource sells building materials, tools, electrical supplies, plumbing fixtures, HVAC equipment, and other trade-specific items, but selection varies by warehouse.
  • You will need to show proof of your business license or contractor license at signup, or meet other requirements if you are a homeowner member.

Types of ProSource Memberships

ProSource offers different membership categories depending on who you are and how you plan to use the warehouse. Contractor memberships are designed for licensed contractors, electricians, plumbers, and other trade professionals. You typically need to show a current business license and contractor license to join this tier. Contractor members usually get the deepest discounts and access to the full range of products.

Business owner memberships are available to people who own a business but may not hold a specific trade license—for example, a property management company or a small construction supply business. Requirements vary, but you will generally need to show proof of business registration or a business tax ID.

Homeowner or DIY memberships exist at some ProSource locations, though availability and requirements differ by warehouse. Some locations require you to show that you own property or have a legitimate need for wholesale materials. Others may have restrictions on how much you can buy or which products you can access. Call your local ProSource warehouse to ask whether they offer homeowner memberships and what you need to bring to sign up.

Membership fees and renewal periods vary by location. Some warehouses charge an annual fee; others may offer different tiers with different price points. Ask about the current cost and what is included before you commit.

ProSource Locations in South Carolina

ProSource operates multiple warehouses across South Carolina, with locations in areas including the Midlands, Lowcountry, and Upstate regions. The exact number and addresses of warehouses can change, so the best way to find the one nearest you is to visit the ProSource website and use their location finder tool, or call their customer service line.

Each warehouse stocks similar core products—building materials, electrical supplies, plumbing fixtures, HVAC equipment, tools, and fasteners—but inventory can vary by location and by season. If you need a specific item, it is worth calling ahead to confirm they have it in stock before making the drive. Many ProSource warehouses also offer special order services if they do not have something on hand.

Hours of operation are typically geared toward contractors and trade professionals, which often means early opening times and closing times that may be earlier than a typical retail store. Check the hours for your local warehouse before you visit, especially if you are planning to stop by after work.

What You Can Buy at ProSource

ProSource stocks a wide range of products used in construction, renovation, and maintenance work. Building materials include lumber, drywall, insulation, roofing materials, and siding. Electrical supplies cover wire, conduit, breakers, outlets, switches, and lighting fixtures. Plumbing includes pipes, fittings, fixtures, valves, and water heaters.

HVAC equipment such as furnaces, air conditioning units, ductwork, and refrigerant are available, though some items may need to be special-ordered. Tools and equipment range from hand tools to power tools to safety gear. Fasteners and hardware like nails, screws, bolts, and hinges are stocked in bulk quantities.

ProSource also carries paint, stain, sealers, and other finishing products, as well as cleaning supplies and janitorial items. Some locations may stock specialty items or have partnerships with manufacturers for exclusive products. The selection at each warehouse depends on the local market and the types of contractors in the area, so what is available in Charleston may differ from what is stocked in Greenville.

Membership Requirements and What to Bring

To join ProSource, you will need to provide proof of who you are and what type of business or work you do. For licensed contractors, bring a current driver's license, proof of your business license, and proof of your contractor license or trade license. Some locations may also ask for a business tax ID or EIN.

For business owners without a specific trade license, bring a driver's license, proof of business registration (such as articles of incorporation or a business license from your city or county), and a business tax ID if you have one. A business bank statement or business credit card can also help establish that you operate a legitimate business.

For homeowners or DIY members, requirements vary widely by location. Some warehouses ask for a driver's license and proof of property ownership (such as a deed or property tax statement). Others may ask you to sign a statement that you are purchasing materials for your own use. Call ahead to ask what your local warehouse requires before you show up to join.

Membership is not transferable—only the person whose name is on the membership can use it to shop. Some locations allow you to add authorized users to your account for an additional fee, but this varies by warehouse.

Pricing and Discounts

ProSource's main advantage is wholesale pricing, which means you pay less per unit than you would at a retail hardware store or building supply chain. However, the actual discount depends on the product category, the brand, and current market conditions. Electrical supplies and plumbing fixtures often have steeper discounts than lumber or building materials, where wholesale and retail prices are closer together.

Many ProSource locations offer additional discounts or promotions for high-volume purchases or for members who buy certain brands regularly. Some warehouses run seasonal sales or clearance events. Ask your local ProSource manager about any current promotions or volume discounts that might apply to your purchases.

Keep in mind that wholesale pricing often requires buying in larger quantities than you might at a retail store. A single item may cost less per unit, but you may need to buy a full box or case rather than just one or two pieces. For homeowners doing a one-time project, this can mean spending more upfront even at a lower per-unit price.

How to get your free guide

Find the ProSource warehouse nearest you by visiting their website or searching online for "ProSource near me" along with your city or zip code. Call the warehouse directly to confirm their hours and to ask about membership requirements for your situation—whether you are a contractor, business owner, or homeowner.

Gather the documents you will need based on your membership type: driver's license, business license, contractor license, proof of business registration, or proof of property ownership. Some warehouses allow you to apply online or by phone, while others require you to visit in person to complete the membership process.

Once you are approved, you will receive a membership card or account number that you use to shop. You can then visit the warehouse during business hours to browse and purchase items, or some locations may offer phone or online ordering for pickup or delivery.

Frequently Asked Questions

Do I need a business license to shop at ProSource?

It depends on your membership type. Licensed contractors and trade professionals need to show their license. Business owners need to show proof of business registration. Homeowners may be able to join at some locations without a business license, but requirements vary by warehouse. Call your local ProSource to ask what they require for your situation.

Can I shop at ProSource if I am just doing a home renovation project?

Some ProSource locations offer homeowner memberships, but not all do. Even if your local warehouse does, they may have restrictions on what you can buy or how much you can purchase. Contact your nearest ProSource warehouse to ask whether they accept homeowner members and what the requirements are.

Is ProSource membership worth it if I only shop there occasionally?

That depends on the membership fee at your location and how much you typically spend. If you are a contractor or business owner who buys materials regularly, the wholesale savings usually pay for the membership quickly. If you shop only once or twice a year, the membership fee may not be worth it unless you are buying a large quantity of items at once.

Can someone else use my ProSource membership card?

Membership is tied to the person whose name is on the account, so technically only you can use it. Some locations allow you to add authorized users to your account for a fee, but this varies by warehouse. Ask your local ProSource whether they offer this option.

What if my local ProSource does not have the item I need?

Most ProSource warehouses offer special order services. Call or visit and ask whether they can order the item for you. Delivery times and fees vary depending on the product and the supplier, so ask about timing and cost before you place the order.
