IMC Powered by Parts Authority is a wholesale buying group for independent repair shops
IMC Powered by Parts Authority is a buying group and distribution system that lets independent auto repair shops, collision centers, and other service businesses purchase parts at wholesale prices. Instead of each shop negotiating separately with suppliers, IMC members pool their buying power to get better rates on inventory. The network is operated by Parts Authority, a distributor that handles warehousing, logistics, and member support.
If you own or work at an independent repair shop, IMC membership means you can order parts through a centralized system rather than calling multiple suppliers. You get access to a shared inventory network, standardized pricing, and delivery options that smaller shops typically cannot negotiate on their own. The system is designed to help independent shops compete with larger chains that have their own supply chains.
Key Takeaways
- IMC is a wholesale buying group for independent repair shops, not a parts retailer for consumers.
- Members access parts at wholesale prices by pooling purchasing power through the Parts Authority network.
- The system includes online ordering, inventory management tools, and delivery logistics handled by Parts Authority.
- Membership is intended for business owners and shop managers, not individual vehicle owners.
- Joining requires operating an active repair or service business and meeting Parts Authority's membership criteria.
Who can join IMC Powered by Parts Authority
IMC membership is open to independent repair shops, collision centers, transmission shops, tire retailers, and other automotive service businesses. You must own or manage an active repair operation — the network does not sell to individual consumers or DIY mechanics. Parts Authority verifies that your business is legitimate and operating before approving membership.
The exact requirements vary by region and by the type of service you provide. Most commonly, you need a valid business license, proof of an active shop location, and sometimes a minimum annual purchase commitment or membership fee. Contact Parts Authority directly to confirm what documentation your specific business type needs to present.
How ordering and pricing work
Once you are a member, you can order parts through IMC's online ordering system or by phone. The system shows you real-time inventory across the Parts Authority warehouse network, so you can see what is in stock before you order. Pricing is set at the wholesale level — lower than retail — and the same for all members ordering the same part.
Delivery typically happens within one to three business days depending on your location and the part's availability. Some shops arrange standing orders for frequently used items, which can reduce both the price and the time spent ordering. Parts Authority handles all logistics, so you do not coordinate directly with multiple suppliers the way you would without membership.
The difference between IMC and buying parts retail
When a repair shop buys parts at retail prices — either online or from a local parts store — they pay the full markup that the retailer adds. That markup covers the retailer's overhead, staff, and profit. IMC members bypass that retail markup by buying directly from the wholesale network, which means lower per-unit costs and better margins on repair jobs.
The trade-off is that IMC requires membership commitment and typically a minimum order volume or annual spend. A one-person shop doing occasional repairs might not save enough to justify membership fees, but a shop doing dozens of repairs per week will see significant savings. The break-even point depends on your shop's size and how many parts you order annually.
Membership costs and what is included
IMC membership involves an initial fee and sometimes an annual renewal cost, though the exact amounts vary by region and membership tier. Parts Authority does not publish a single standard fee — you receive a quote based on your business type, location, and expected volume. Some memberships include a minimum annual purchase requirement; others do not.
What is typically included: access to the online ordering system, real-time inventory visibility, wholesale pricing on parts, delivery logistics, and customer support from Parts Authority. Some membership levels may include additional services like business tools, training, or marketing support. Ask Parts Authority what each tier includes when you inquire about joining.
How to explore IMC membership for your shop
Start by visiting the Parts Authority website or calling their membership team directly. Have your business license, shop address, and a rough estimate of your annual parts spending ready. They will ask about your business type, location, and current suppliers to determine which membership option fits your operation.
Parts Authority will provide you with membership terms, pricing, and next steps. If you decide to join, they will set up your account, provide login credentials for the ordering system, and assign you a support contact. Most shops can begin ordering within a few days of approval.
Frequently Asked Questions
Can I use IMC if I run a very small shop or work solo?
You can join, but whether it makes financial sense depends on your volume. If you order parts only occasionally, the membership fee might outweigh your savings. Parts Authority can estimate your potential savings based on your current spending before you commit.
What if I need a part that is not in the IMC network?
IMC covers a wide range of common and specialty parts, but not every single item exists in every warehouse. Parts Authority can often source parts outside the standard network, though it may take longer and the pricing may not be wholesale. Ask your support contact about special orders.
Do I have to buy all my parts through IMC once I join?
No. Membership does not require exclusivity. Many shops use IMC for the majority of their parts but still buy from other suppliers for specialty items or when IMC does not have what they need. There is no penalty for using other sources.
How does IMC handle returns or defective parts?
Parts Authority has a return and warranty process for defective inventory. The specifics depend on the part type and how long you have had it. Your membership agreement and support team will explain the return policy when you join.
Is there a contract or can I cancel anytime?
Membership terms vary. Some memberships are month-to-month; others require a commitment period. Ask Parts Authority about the cancellation terms before you sign up so you understand what you are agreeing to.
