Staffing a Growing Building Materials Supplier

A commercial building material supplier hires across three very different worlds under one roof: outside sales reps who build relationships with contractors, yard and warehouse staff who move product safely and efficiently, and CDL delivery drivers who keep job sites supplied on schedule. Treating all three the same way when you're deciding between RPO, contingent search, and in-house hiring wastes money on at least two of them.

Here's how to split hiring across the roles that actually run a building materials business.

Outside Sales: Relationships Are the Whole Job

An outside sales rep who already has relationships with local contractors and builders is worth more than one with a longer resume but no local book of business. That makes outside sales a relationship-driven hire closer to what a contingent search firm is built for, especially when you're trying to poach an experienced rep from a competitor rather than train someone from scratch.

Screen hard for actual relationships during interviews, not just years of experience in the category. Ask specific questions about which accounts a candidate has served and how they'd bring that business with them, since that's the real value a sales hire brings on day one.

Yard and Warehouse: Build a Repeatable Pipeline

Yard supervisors and warehouse staff are roles most suppliers refill regularly as volume grows or turnover happens, which makes this a strong candidate for an RPO relationship or a solid internal pipeline. These roles have clear, checkable qualifications, forklift certification, safety record, physical capability, that a structured screening process can evaluate consistently without needing a specialized recruiter each time.

Keep safety screening non-negotiable regardless of how you source candidates: verify certifications and check safety references before an offer, not after someone's already on the floor.

CDL Delivery Drivers: A Volume Hiring Problem

Delivery drivers with a valid CDL are, like long-haul trucking, more of a continuous, high-volume recruiting problem than a project-based search. Most suppliers are better off running driver recruiting as an always-on internal function, job boards, referral bonuses, driver-specific platforms, rather than paying a per-placement search fee for a role you'll fill repeatedly.

If your delivery fleet is growing fast enough that internal recruiting can't keep pace, an RPO-style partner running that pipeline at scale is a better fit than a traditional contingent search firm built around white-collar placement fees.

Where Credit and Collections Roles Fit

Credit and collections staff sit closer to a standard office hire: not as relationship-dependent as outside sales, not as volume-driven as drivers or yard staff. Most suppliers can fill these roles in-house or through a light-touch contingent search for a more senior credit manager role, without needing the ongoing pipeline an RPO relationship assumes.

Cost per hire for these office roles tracks close to the national nonexecutive average of about $5,475, rising toward $35,879 for a senior credit or finance leadership hire1. Budget accordingly and don't over-invest in outside recruiting for roles your own network can likely fill.

A Worked Example: Opening a Second Branch

Say a supplier is opening a second branch location within driving distance of its original yard. The new branch needs a yard supervisor and two warehouse staff, roles you can route through the same pipeline that's worked for your existing location, whether that's RPO or an internal referral process. It also needs an outside sales rep who can bring relationships in the new territory, which is a better fit for a contingent search firm if your own network doesn't reach that area yet.

Delivery drivers for the new route can usually be sourced through the same always-on driver recruiting process you already run, just started earlier to have a base in place before the branch opens.

Common Mistakes When Splitting Hiring Across Roles

The most common mistake is paying a contingent search fee for a yard or warehouse role that a standard job posting and referral bonus would have filled just as well, treating every opening as if it needs specialized outside help. Reserve search fees for the roles where relationships or scarce skill genuinely justify the cost.

The opposite mistake also happens: trying to fill an outside sales role with a general job posting when the real value of the hire is an existing book of business, then wondering why the pipeline is full of candidates with no local contractor relationships at all. A generic posting simply doesn't reach the people who already have what you're actually paying for.

A third mistake is under-investing in driver recruiting because it feels like the least glamorous hiring problem in the business, then discovering a delivery shortfall is quietly costing more in missed job-site deliveries and strained customer relationships than any other staffing gap. Treat driver pipeline health as seriously as you treat sales pipeline health.

Suppliers waste hiring budget in these ways:

  • Paying a contingent search fee for a yard or warehouse role that a standard job posting and referral bonus would have filled just as well.
  • Treating every opening as if it needs specialized outside help, instead of reserving search fees for roles where relationships or scarce skill justify the cost.
  • Running CDL driver recruiting as a per-placement search, when an always-on function using job boards, referral bonuses and driver-specific platforms fits better.
  • Hiring an outside sales rep without weighing existing contractor relationships more heavily than resume length.
Executive Capability Standard

What Good Looks Like

A well-run building materials supplier routes each role to the recruiting approach that fits it: relationship-driven search for outside sales, a repeatable pipeline for yard and warehouse staff, and always-on recruiting for delivery drivers.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Break down your last year of hires by role type and note which behaved like a relationship search, a pipeline hire, or a volume hire.
2. Do Manually:Source yard and warehouse roles directly through referrals and local job boards before paying for outside help.
3. Delegate:Assign an ops or branch manager to own screening for repeatable roles, keeping sales hiring with whoever manages the sales team.
4. Automate:Standardize safety certification checks and a driving record review so every candidate clears the same bar before an offer.
5. Buy:Use a contingent search firm for outside sales reps with existing relationships, and an RPO partner if driver or yard hiring volume outpaces your internal team.

Frequently Asked Questions

Should outside sales reps be hired through a contingent search firm?

Often yes, especially when you're trying to bring in a rep with existing contractor relationships rather than train someone from scratch. A firm with real building materials or construction-supply placements can reach experienced reps who aren't actively job hunting, which is usually where the strongest candidates come from.

Is RPO worth it for a supplier with only one location?

It depends on your hiring volume across yard and warehouse roles specifically. If you're refilling those positions several times a year due to growth or turnover, a standing pipeline pays off. With a single small location and low turnover, sourcing directly and using contingent search for the rare specialized hire likely costs less.

How should we hire CDL delivery drivers differently from long-haul truckers?

The core approach is similar: treat it as continuous, high-volume recruiting rather than a one-time search, using job boards, referral bonuses, and driver-specific platforms. Delivery routes are typically local, which can widen your candidate pool compared to over-the-road roles, but the sourcing playbook stays largely the same.
