Procurement teams sourcing from aerospace hardware distributors often discover that the relationship works best once it moves past a simple purchase order. Vendor managed inventory, or VMI, is one of the clearest examples of that shift. Instead of a customer tracking usage and placing reactive orders, the distributor takes on that responsibility, monitoring stock levels and replenishing parts before a shortage ever becomes a production problem. For teams juggling hundreds of part numbers across multiple programs, that difference in approach can matter as much as the parts themselves.
What Aerospace Hardware Distributors Actually Do
Distributors occupy a different role than manufacturers in the aerospace supply chain. Manufacturers produce components at scale, which suits large production runs well. Distributors stock those components across a wide range of part numbers and offer flexibility on order size, lead time, and specialized requirements. That flexibility becomes especially valuable when a program needs prototype quantities, a fast turnaround, or a mix of parts from multiple manufacturers consolidated under one relationship. Aerospace hardware distributors who also run VMI programs extend that value further, because they are not just holding inventory, they are actively managing it on the customer’s behalf.
Why Reactive Ordering Falls Short
Traditional purchase order processes ask a customer to track consumption, forecast demand, and place an order before stock runs out. That works fine until demand shifts unexpectedly or a part gets overlooked during a busy quarter. A missed reorder can stall an assembly line, and a rushed one often costs more than a planned order would have. Because aerospace programs frequently involve regulatory scrutiny and tight production schedules, the margin for that kind of error stays small. Distributors who understand this risk have increasingly built VMI programs specifically to remove it from the customer’s plate.
How VMI Shifts the Relationship
Under a VMI arrangement, an aerospace hardware distributor monitors real-time consumption data and manages replenishment directly, often through automated tracking tools rather than manual counts. That data sharing allows the distributor to spot usage trends early and adjust stocking levels before a shortage develops. It also reduces the administrative burden on the customer’s side, since fewer purchase orders need to be issued and tracked individually. One FTS customer saw purchase order line items drop from thousands per year down to twelve consolidated statements after adopting this model, while on-hand inventory shifted from roughly six months of stock down to a single day’s worth on the floor.
What to Look for in a VMI-Capable Distributor
Not every distributor offering VMI runs the program the same way, so a few criteria are worth checking before committing to one. Certification status matters first, since AS9100 registration confirms an independent audit of a distributor’s quality systems against aerospace-specific requirements. Real-time visibility matters just as much, since a VMI program without transparent data sharing puts the customer back in the position of guessing. Delivery and quality performance history over time tends to be a better predictor of reliability than a single reference or a low quote.
| What to Check | Why it Matters |
|---|---|
| AS9100 certification | Confirms an audited, aerospace-specific quality system |
| Real-time inventory visibility | Prevents stockouts without manual tracking |
| Consolidated PO processing | Reduces administrative burden on procurement teams |
| Documented delivery history | Predicts reliability better than price alone |
Data Security Belongs in the Conversation Too
Quality and delivery aren’t the only things worth vetting in an aerospace hardware distributor, especially for programs that touch defense work. Any distributor handling Controlled Unclassified Information should be able to speak to how they protect it. FTS is actively working toward CMMC 2.0 certification and aligning its security practices with NIST 800-171 guidelines, alongside maintaining compliance with DFARS and other applicable regulations. For procurement teams managing sensitive defense programs, that kind of security posture is becoming as relevant to the sourcing conversation as certification and delivery history.
Making VMI Work for Your Program
There is no single VMI setup that fits every aerospace program, since the right structure depends on part volume, plant count, and how tightly a customer wants to control the replenishment process. What stays consistent across successful programs is communication, since a distributor who flags a potential issue early prevents far more disruption than one who only reacts after a shortage appears. Aerospace hardware distributors who treat VMI as an ongoing partnership, rather than a one-time setup, tend to deliver the kind of consistency that production schedules depend on.
