Hiring Commercial Cleaning for the First Time: Common Mistakes and What to Ask in the First Meeting

Summary

If this is your first time hiring commercial cleaning services, you likely don't lack information, but rather structure: you don't know what to decide first, what to ask, or how to recognize a clear answer. This article addresses the most common questions, outlines the mistakes almost every beginner makes, proposes 18 questions for your first meeting with a vendor (along with what to look for in each response), and concludes with a five-step roadmap to obtaining quotes you can actually compare. It does not include pricing or make claims about any specific vendor.

The short answer

In the first meeting, you don't need to be a cleaning expert; you need to get the vendor to explain how they understand your facility, who will do the work, how they will verify it, and what is included (and what is excluded) in their quote. Arrive with three things: a description of your facility and what is currently being done, a clear idea of your concerns (quality, continuity, compliance, budget), and the list of questions below. Do not ask for a firm price yet: without a written scope of work, a price only tells you what assumptions the vendor made. After the meeting, the structured path is to define the scope, send the same document to multiple vendors, and compare them against predetermined criteria.

Questions almost everyone starts with

• "How much should it cost?" There is no single figure: it depends on square footage, frequency, operating hours, staffing, supervision, and supplies. A price without a defined scope cannot be evaluated; see the breakdown in what makes up the price of commercial cleaning.
• "What does 'office cleaning' (or warehouse, or building cleaning) include?" Every vendor may interpret this differently. That is why it is essential to define the scope in writing; the article on what commercial cleaning services include helps assign specific names to each task.
• "Do I have to hire an outside company, or can I stick with in-house staff?" It is a legitimate decision either way. The evaluation criteria are outlined in in-house staff or outsourced cleaning vendor.
• "They are asking me for 'REPSE' and I don't know what it is." It is the mandatory registry in Mexico for companies providing specialized services. A straightforward explanation is available in what REPSE is explained for companies.
• "How many quotes should I request, and how do I compare them?" Use the exact same document for all bidders and establish an evaluation matrix before looking at prices (comparing cleaning proposals).
• "What if I make a mistake?" A well-drafted contract and structured operational oversight allow you to make corrections. The goal is not necessarily to get everything perfect on day one, but to be able to measure and adjust as needed.

If you inherited the service

Anyone stepping into a role with an existing vendor already contracted often doesn't even know what was originally agreed upon. Before forming an opinion on whether the service is good or bad, gather existing documentation: the contract and its exhibits, the list of areas and cleaning frequencies, the vendor's compliance file, recent logs or reports, and any logged complaints. If there is no written scope of work, that is your first finding, not anyone's fault. With these documents, you can ask the current vendor the questions in this article, review their compliance file, and, if doubts persist, review the signs to evaluate your cleaning service before deciding whether to correct, renegotiate, or rebid.

Common mistakes when hiring for the first time

1. Starting with price. Requesting "a quote" without describing the facility produces arbitrary numbers that cannot be compared.
2. Leaving the scope in someone's head. If the scope only exists in the requester's mind, no one will be able to enforce it or measure performance.
3. Judging everything by a single day's appearance. Without a written definition of "clean" for each type of area, every walkthrough is merely subjective opinion.
4. Trusting a document without verifying it. Receiving a compliance certificate is not the same as verifying its validity directly with the official registry.
5. Failing to ask what happens when someone is absent. A cleaner assigned to a shift does not work 365 days a year; how days off, vacations, and unexpected absences are covered determines your operational continuity.
6. Forgetting supplies and equipment. If it is unclear who provides toilet paper, soap, trash liners, or machinery, these will soon appear as unexpected charges or service shortages.
7. Closing with the first vendor that interviews well. Without at least one alternative proposal based on the same scope, you won't know what is actually included in the proposal you liked.
8. Signing without an exit strategy. A contract with no clear termination or transition clause becomes a serious issue the day you need to make a change.
9. Giving direct orders to the vendor's cleaners. While doing so is an understandable reaction ("clean here"), you should always route your observations through the vendor's supervisor and maintain a written log (see the legal section).

Before the meeting: what to have on hand

You don't need a comprehensive file; a single page with the following information is enough:

• Facility type, location, and operating hours (including allowable cleaning windows).
• Main areas (offices, restrooms, warehouse, loading docks, break rooms, outdoor areas) and flooring types, even if approximate estimates.
• Current cleaning practices and who performs them (in-house staff, existing vendor, no one).
• Primary concerns and what a successful outcome would look like after six months.
• Site restrictions: sensitive product areas, restricted zones, access badges, security and safety rules.
• Stakeholders: who makes the purchasing decision, who signs the contract, and who manages the day-to-day service.

With this information, the vendor can ask better questions, and you can evaluate their expertise by the questions they ask. A site walkthrough before quoting often clarifies more than any written description.

The 18 questions for the first meeting

Group them by topic, take detailed notes, and ask the same questions to each vendor. The right-hand column indicates what to look for; it is not a formal score.

How to read the answers

A solid answer is specific, verifiable, and clearly states its underlying assumptions. A vague answer does not necessarily indicate bad faith: it often means the vendor does not yet have enough information about your facility. That is why these same questions should be revisited after the on-site walkthrough.

Three red flags that warrant deeper inquiry, without drawing premature conclusions:

• "Everything is possible." If every request gets an immediate "yes" without questions about your facility, request that they put the commitment and its precise scope in writing.
• Documents that will be "sent later." Request a firm deadline. For anything that can be checked in an official government registry, verify it yourself.
• A price that drastically differs from the others. Whether significantly lower or higher, ask what is included and excluded before drawing conclusions.

This meeting is not the final evaluation: formal vendor comparisons should be conducted using an evaluation matrix, with scoring criteria established before reviewing pricing.

The bare minimum to know about the legal side

This section is intentionally concise; complete details are linked and should always be validated by your legal counsel.

• Staffing vs. Service. Under Mexico's Federal Labor Law (*Ley Federal del Trabajo* or LFT, text consulted with last reform noted: 05-14-2026), Article 12 prohibits personnel subcontracting, while Article 13 permits subcontracting specialized services or works that do not form part of the client's corporate purpose (*objeto social*) or predominant economic activity. In practice, you are hiring a service that the contractor organizes, directs, and supervises—not personnel placed at your disposal. For this reason, when you notice something that needs correction, communicate it directly to the vendor's supervisor.
• Registration (REPSE). Article 15 mandates that specialized service providers hold a valid registration with the Ministry of Labor and Social Welfare (*Secretaría del Trabajo y Previsión Social* or STPS), renewable every three years. This public registry is accessible at repse.stps.gob.mx, where you can search by company name, tax ID (RFC), or registration number (folio) to confirm registration status, validity, and authorized activities. A step-by-step verification guide can be found in verifying a cleaning vendor's REPSE.
• Contracts and Joint Liability. Article 14 requires a written contract specifying the specialized service to be performed and the approximate number of workers involved. It also establishes joint and several liability (*responsabilidad solidaria*) for the hiring entity if the contractor fails to meet its labor and social security obligations to its staff. This liability is the primary reason facility managers must demand and archive compliance documentation. Key clauses are detailed in what the cleaning service contract must say.
• Tax Deductibility. Article 15-D of Mexico's Federal Fiscal Code (*Código Fiscal de la Federación* or CFF, last reform noted: 04-09-2026) conditions the tax deductibility (ISR) and crediting (IVA) of these service payments on various compliance requirements, including verifying that the contractor holds a valid Article 15 LFT registration. Your corporate tax advisor must determine how this applies to your organization.
• Contractor Reporting. Registered contractors must file quarterly reports on their active contracts. For the National Workers' Housing Fund Institute (*Infonavit*), filings are submitted through the Subcontracting Information System (*SISUB*, portalmx.infonavit.org.mx, reporting windows: May 1–17, September 1–17, and January 1–17; page updated Sep 10, 2026). Requesting proof of these filings is an internal risk control, not a statutory obligation imposed directly on the client.
• Chemical Products. Mexican Official Standard NOM-018-STPS-2015, which governs the identification and hazard communication of chemical substances in the workplace (published in the Official Gazette on Oct 9, 2015, and in effect per the official catalog), provides the regulatory basis for requiring chemical Safety Data Sheets (SDS). Your Environmental Health and Safety (EHS) team should determine the specific site obligations for both parties.
