When a mid-size or large food manufacturing facility in the United States sends out an RFP for sanitation services, price is rarely the deciding factor once proposals start coming in. What actually separates a qualified vendor from a risky one is whether they can prove their own food safety credentials hold up to the same scrutiny your facility faces during certification audits. A sanitation crew can look professional on a walkthrough, but if they can’t produce the right documentation, your facility inherits that risk the moment they step onto your production floor.
This guide breaks down exactly which certifications and audits to look for when evaluating contract sanitation vendors during the RFP process and why skipping this step can jeopardize your own certification standing.
Why Vendor Certification Status Matters Before You Sign
Any vendor working inside a certified food manufacturing facility becomes part of that facility’s food safety system in the eyes of an auditor. If your plant holds SQF Certification, your auditor will expect to see evidence that your sanitation vendor’s practices, training, and chemical handling align with SQF’s prerequisite program requirements not just that the floor looks clean on the day of the visit. The same applies if your facility operates under BRC Certification, where documentation control and traceability extend to any third party performing work that touches food-contact surfaces.
Vetting a vendor’s certification status during the RFP stage rather than after a contract is already signed is the only way to confirm they understand what your auditors will actually be looking for.
Audits and Credentials to Request in Every RFP
When evaluating proposals, ask each vendor to provide documentation for the following, rather than taking verbal assurances at face value:
- Proof of an internal or third-party SQF Audit history, if the vendor works across multiple SQF-certified facilities and can speak to how their program supports SQF prerequisite requirements
- CFS Audit documentation, where applicable, showing the vendor has been evaluated against Commercial Food Sanitation standards specific to your industry segment
- Chemical safety and handling certifications, confirming staff are trained on proper dilution, application, and storage of sanitation chemicals used in food environments
- Employee training records and GMP certification, showing sanitation crews understand food-contact surface protocols, allergen cross-contact prevention, and foreign material control
- Insurance and liability documentation specific to food manufacturing environments, not just general commercial liability
A vendor providing genuine Contract Sanitation services to certified food facilities should be able to produce this documentation quickly. Hesitation or vague answers at the RFP stage is often a preview of how they’ll handle documentation requests during your actual audit.
Red Flags to Watch for During Vendor Evaluation
Some warning signs are worth flagging before a vendor makes it to a final round of consideration:
- No documented training program specific to food manufacturing environments
- Inability to name which food safety standards their existing clients are certified against
- No process for tracking chemical lot numbers or safety data sheets
- No experience supporting a facility through an actual certification audit cycle
- Pricing significantly below other bids with no clear explanation for the gap
Building This Into Your RFP Scoring Process
Rather than treating certifications as a pass/fail checkbox, build them into your RFP scoring criteria alongside price and service scope. A vendor with strong food safety credentials may cost more per month, but they reduce your facility’s exposure to audit non-conformances, corrective action delays, and the reputational risk of a failed inspection tied back to a third-party provider.

If your facility is preparing for its own certification audit while evaluating vendors, our SQF Audit Preparation Checklist can help you align vendor requirements with what your auditor will actually be reviewing.
Verifying Vendor Claims Before You Award the Contract
Certifications listed on a proposal are only useful if they can be verified. Before finalizing an RFP decision, it’s worth confirming a vendor’s claims independently rather than relying on their own documentation alone. Our resource, How to Verify a Business Meets High Sanitation Standards & Food Safety Compliance, walks through practical steps for confirming a vendor’s food safety standing before you sign.
Frequently Asked Questions
Does a sanitation vendor need to be SQF certified themselves to work in an SQF facility?
Not necessarily. Many vendors aren’t independently SQF certified, but they should be able to demonstrate that their training, chemical handling, and documentation practices align with SQF prerequisite program requirements, since their work will be reviewed as part of your facility’s own audit.
What is a CFS Audit and why does it matter for sanitation vendors?
A CFS Audit evaluates a vendor or facility against Commercial Food Sanitation standards specific to their operational practices. Vendors who have undergone this type of audit typically have more mature documentation and training programs already in place.
Should price or certifications matter more when scoring an RFP?
Both matter, but certifications and documented food safety practices should be weighted heavily, since a vendor with weak food safety credentials can create costly non-conformances or delays during your own facility’s certification audits.
How can I verify a vendor’s certification claims during the RFP process?
Request original documentation rather than summaries, ask for references from other certified food facilities they currently service, and confirm training records directly rather than accepting general assurances.
What happens if a sanitation vendor’s practices cause a non-conformance during my facility’s audit?
The responsibility ultimately falls on your facility, since auditors evaluate the food safety system as a whole, including third-party contractors. This is why vetting vendor certifications during the RFP stage is critical, not optional.
Choosing a contract sanitation vendor without verifying their food safety credentials puts your facility’s own certification status at risk. Building certification and audit history into your RFP evaluation process is one of the simplest ways to protect your audit outcomes before a vendor ever sets foot on your floor.
