Vendor Vetting Checklist for Commercial Cleaning Contracts

Switching cleaning vendors is disruptive, so most property managers would rather vet a new vendor thoroughly upfront than discover problems six months into a contract. This checklist covers the questions worth asking before signing a recurring commercial cleaning agreement.

Insurance and Documentation

• Does the vendor carry general liability insurance appropriate for commercial cleaning operations?
• Will they provide a certificate of insurance before or at the time of the written quote, without you having to request it separately?
• Can they add your company as an additional insured if your management agreement requires it?

A vendor who treats insurance documentation as a routine, easy-to-produce part of quoting — rather than something you have to chase down after signing — is signaling how they handle administrative follow-through generally.

Scope of Work Practices

• Do they provide a written, area-by-area, task-by-task scope of work, or just a verbal description of "standard cleaning"?
• Can they show a sample scope for a comparable building type and size?
• Is frequency defined at the task level, or just as a single blanket visit frequency?

A thorough written scope of work, covering every area and task at a defined frequency, is the right benchmark when reviewing a vendor's proposal.

Scheduling and Communication

• Is there a single named point of contact for your account, or a general call center?
• What are their office hours, and what happens if you need to reach them outside those hours?
• How do they handle schedule changes — holidays, building closures, temporary frequency adjustments?
• What's their process if a scheduled visit is missed?

Vague or evasive answers here are a warning sign. A vendor confident in their operations should be able to describe their communication process specifically, not just say "we're very responsive."

Pricing Transparency

• Is the quote written, with a defined scope attached, or a verbal number with no documentation?
• Are there clearly defined processes for pricing changes if your scope or frequency changes later?
• Are add-on services (deep cleans, one-time requests) priced separately and disclosed upfront, or bundled ambiguously?

References and Track Record

• How long has the vendor operated in your market specifically?
• Do they focus on commercial recurring contracts, or split attention across residential and one-time jobs?
• Can they speak knowledgeably about your building type (medical, office, retail, industrial) rather than giving generic answers?

A vendor that focuses specifically on commercial recurring contracts, rather than splitting attention across residential maid service and one-time jobs, is more likely to have built scheduling and account management systems suited to long-term accounts.

Red Flags to Watch For

• No written scope of work offered. If a vendor can't or won't put the scope in writing before you sign, that ambiguity becomes your problem later.
• Reluctance to provide insurance documentation. This should be a routine request, not a negotiation.
• Vague frequency language. "We'll clean as needed" or "regular visits" without specific defined intervals leaves too much room for drift.
• No single point of contact. If every question routes through a general number with no continuity, expect slower resolution on real issues.
• Unrealistic availability claims. A vendor claiming 24/7 phone coverage that isn't actually staffed sets an expectation they can't meet. Honest office hours with a clear callback commitment are more reliable than an inflated availability promise.

Making the Switch

If you're replacing an existing vendor, plan the transition to avoid a service gap: confirm the new vendor's start date, coordinate any handoff of access credentials (keys, fobs, alarm codes), and give your outgoing vendor appropriate notice per your existing agreement. A well-planned transition with a new vendor who provides a real written scope of work from day one sets the account up to run smoothly for years rather than requiring another vendor search in twelve months.

Questions to Ask During the First Call

Beyond the checklist above, a first call with a prospective vendor is a good opportunity to gauge how they operate day to day. Ask how they handle a missed or late visit, whether the same crew returns to your building each time or a rotating pool is assigned, and how they'd approach a building with your specific traffic pattern (multi-tenant, medical, retail, or industrial). Specific, direct answers — rather than generic reassurances — are usually the better signal.

Evaluating the Proposal Itself

Once you receive a written proposal, compare it against your current or prior vendor's scope line by line if you have one. Look for whether task frequency is defined per area (not just a single blanket "weekly" or "nightly" label), whether restroom supply restocking is explicitly included, and whether the price includes the full scope or defers common tasks to a separate add-on list. A proposal that reads clearly and matches what was discussed on the phone is a good sign; a proposal that's vague or inconsistent with the conversation is worth a follow-up call before signing.
