Grainger is one of the largest MRO (maintenance, repair, and operations) suppliers in North America, and its Net 30 account is a staple way for HVAC contractors to access credit terms on thousands of line items - everything from capacitors, contactors, and motors to shop tools, PPE, and HVAC-specific parts like condensate pumps and filter media. Balances are due on Net 30 terms (30 days from invoice or shipment date), giving shops a month of float to invoice the customer and collect payment before the supply bill comes due. For many HVAC shops, Grainger is the go-to source for emergency parts or overnight shipment when local supply houses are out of stock.
Layered on top of the base Net 30 account is KeepStock, Grainger's inventory management program. KeepStock options range from self-service vending machines and CribMaster industrial dispensers in the shop to vendor-managed replenishment where Grainger reps walk the warehouse and restock bins on a set schedule. For larger HVAC shops, KeepStock eliminates stockouts on common consumables (screws, fittings, tape, filters) and gives managers real-time visibility into usage by tech or truck. Purchases flow through the Net 30 account for consolidated monthly billing.
The Grainger Net 30 account is particularly valuable for business credit building: Grainger reports payment history to Dun & Bradstreet (minimum $50 per order qualifies for reporting), which helps HVAC shops establish a tradeline used by other lenders. The standard credit limit is $1,000 but can be increased to $5,000 or higher with a phone call or account review. There's no personal credit check to open the account.
