Vendor Management for PMs: 3 Vendors Per Trade, Always

Your one plumber is on vacation. A pipe bursts at 11pm. You scramble to find someone, anyone, who can respond tonight.

That scramble disappears when you have three plumbers on your approved vendor list. Plumber A is unavailable. Plumber B answers. Problem solved. No emergency Googling. No unknown contractors entering your owner's property.

Three vendors per trade is the minimum for every PM company. Not two. Not one. Three. Here is why and how to build the network.

Why Three Per Trade?

Availability

One vendor gets sick, goes on vacation, or gets overloaded with jobs. Two vendors reduces the risk but still leaves you exposed if both are unavailable (holiday weekends, extreme weather events, peak season). Three vendors means someone is always available.

Pricing Leverage

With one vendor, you have no leverage. Their price is your price. With three vendors, you can compare quotes on non-emergency work. That competition keeps pricing honest.

We do not recommend always choosing the cheapest vendor. Reliability and quality matter more than saving $50 on a repair. But having options prevents any single vendor from charging whatever they want because they know you have no alternative.

Quality Control

When a vendor knows they are one of three options, their quality stays high. If their work slips, you shift work to the other two. That natural accountability is more effective than any conversation about quality standards.

Which Trades Need Coverage?

At minimum, maintain three vendors for these core trades:

• Plumbing (emergency and scheduled)
• Electrical (emergency and scheduled)
• HVAC (emergency, scheduled, and seasonal)
• General handyman (small repairs, touch-ups, miscellaneous)
• Appliance repair
• Locksmith
• Cleaning/make-ready (turnover cleaning)
• Landscaping/snow removal (seasonal)
• Pest control
• Roofing

For specialty trades (foundation, pools, fire systems), two vendors may be sufficient since these are less frequent.

How to Find and Vet Vendors

Finding Vendors

• Ask other PM companies in your area (non-competing markets if possible)
• NARPM chapter meetings are excellent vendor networking events
• Check with your PM software vendor directory (AppFolio, Buildium, and Rent Manager all have vendor networks)
• Home inspection companies often have vendor lists for trades they encounter during inspections

Vetting Requirements

Every vendor on your approved list must provide:

1. Valid business license for your jurisdiction
2. General liability insurance (minimum $1M, naming your company as additional insured)
3. Workers compensation insurance (required if they have employees)
4. W-9 for tax reporting (you will issue 1099s at year-end)
5. References from other PM companies (not just homeowners)

Do not skip insurance verification. If an uninsured vendor's employee is injured on your owner's property, the liability falls on you and the owner. That single event can cost more than every vendor discount you have ever received.

Ongoing Requirements

• Annual insurance certificate renewal (set calendar reminders)
• Quarterly quality review (spot-check completed work orders)
• Annual pricing review (compare against market rates)
• Response time tracking (how fast do they respond to emergency and non-emergency requests?)

The Vendor Relationship

Set Clear Expectations

Every vendor gets a written scope of work agreement covering:

• Response time expectations (emergency: 2 hours, urgent: 24 hours, routine: 3 business days)
• Communication requirements (update tenant/PM on arrival and completion)
• Invoicing requirements (itemized invoices within 48 hours of completion)
• Photo documentation (before and after photos for every job)
• Pricing structure (hourly rate, trip charge, material markup)

Pay Promptly

The fastest way to lose good vendors is slow payment. Pay invoices within 14 to 21 days. Vendors who know they will be paid quickly prioritize your work over clients who pay in 60 to 90 days.

Volume vendors may offer discounts for prompt payment. A 5% to 10% discount for net-14 payment is common and directly reduces your maintenance costs (or increases your coordination fee margin).

Do Not Micromanage

Set the expectations. Let the vendor execute. Follow up on results, not process. Good vendors know how to do their jobs. Micromanaging skilled tradespeople damages the relationship and slows down work.

Build Loyalty Through Volume

Your 200-door portfolio generates hundreds of work orders per year. That volume is valuable to vendors. Use it as leverage for better pricing, faster response times, and priority scheduling.

But deliver on the implicit promise. If you tell a vendor "we will send you most of our plumbing work," actually do it. Splitting work evenly across all three vendors means nobody gets enough volume to prioritize you.

Our approach: One primary vendor per trade gets 60% to 70% of work orders. Two backup vendors split the remainder. The primary vendor gets enough volume to treat you as a priority client. The backup vendors get enough to stay familiar with your properties and expectations.

Vendor Rebates and Coordination Fees

Your vendor relationships can generate revenue through two mechanisms:

Maintenance coordination fee: A 10% markup on every vendor invoice. This compensates you for dispatching, quality verification, invoice processing, and owner communication. It is charged to the owner.

Vendor rebate: Negotiate a percentage rebate from vendors on total invoices paid. This is your compensation for providing them with consistent volume. The rebate comes from the vendor's margin, not from a markup to the owner.

Some companies do both: charge the owner a coordination fee AND receive a vendor rebate. This works in markets where maintenance markups are standard. In markets where they are not, the rebate gives you vendor revenue without a visible markup.

Start Building This Month

1. List every trade your properties need
2. Count your current vendors per trade
3. Identify gaps (trades with fewer than 3 vendors)
4. Request referrals from your NARPM chapter, other PMs, and your existing vendors
5. Vet new vendors against the checklist above
6. Set up vendor profiles in your PM software

A complete vendor network is a competitive advantage. Properties get maintained faster. Owners are happier. Tenants renew leases. And your revenue per door benefits from both the coordination fee revenue and the reduced maintenance costs.

Three vendors per trade. No exceptions. Build the network now.
