- Review termination and notice provisions before setting dates.
- The four weeks are an adaptable example, not a guaranteed timeframe.
- Changing providers does not automatically mean transferring workers.
The Short Answer
Switch providers when problems are recurring, documented, and unresponsive to an agreed corrective action plan. Address problems with the current provider when they are isolated or standards were never defined in writing. If you decide to switch, do not give notice or end service until three things are in place: Legal has reviewed the current contract, the new provider's documentation has been verified, and an overlap period has been scheduled. Then organize the change over four weeks: prepare, hand over, operate in parallel, and stabilize.
Switch Providers or Correct the Problems?
Concern about change is reasonable. The useful question is: "Did I try to correct the problems using data, without success?"
| Warning Sign | Usually Indicates | First Action |
|---|---|---|
| Isolated complaints from one area or shift | Supervision or frequency issue | Correct: hold a meeting with evidence and a review date |
| Standards never put in writing ("we used to do it this way") | Undefined scope | Correct: document the scope, frequencies, and acceptance criteria |
| Repeated failures with the same root cause, already reported in writing | Structural failure | Consider switching, with a documented prior corrective action plan |
| Unresolved high turnover that affects quality | Team management | Request a plan; if there is no improvement, consider switching |
| Expired documentation or documentation the provider does not submit | Compliance risk | Request updated documentation by a deadline; if not provided, escalate to Legal |
| Changes in facilities or shifts the provider cannot accommodate | Scope differs from the contract | Renegotiate; if capacity is lacking, consider switching |
| Price as the only reason | Incomplete comparison | Compare scope, coverage, and transition cost |
When to wait. If the contract expires in a few weeks, that natural endpoint may be cleaner than early termination. Also avoid starting during an operational peak (inventory counts, audits) without clear dates.
Before deciding, gather two or three months of evidence: reports, inspections, emails, and meeting minutes.
Before Giving Notice: The Current Contract
This is where improvisation is most common. Review these general points with Legal:
- Contract term and end date, and whether renewal is automatic.
- Termination notice: deadline, format (in writing, to whom, with what acknowledgment of receipt), and whether it can be given at any time or only at expiration.
- Penalties or charges for early termination.
- Grounds for termination for cause and the specified procedure.
- Handover obligations at termination: return of keys, access credentials, cards, equipment and supply inventories, information, and reports.
- Outstanding payments and guarantees, if any.
- Confidentiality and personal data obligations that survive termination.
If a breach could justify early termination, the process depends on the signed contract and applicable law; that is for Legal to determine. Do not give informal notice before the process is defined.
What Gets Handed Over
Assign an owner to each item.
| Item | What to Give the New Provider | Who Validates |
|---|---|---|
| Access Credentials and Keys | List of areas, schedules, cards, keys, and codes; reassignment or replacement of those held by the outgoing provider | Security / Operations |
| Inventories | Equipment, machinery, carts, supplies, and chemicals belonging to the client versus those belonging to the provider | Operations |
| Area Sheets and Routines | Area layout, frequencies, tasks by shift, critical zones, access rules | Operations |
| Safety Data Sheets | Sheets for products that remain on-site | EHS / Operations |
| Schedule | Dates for periodic services (deep cleaning, windows, floor maintenance) | Operations |
| Contacts | Shift leads, escalation chain, reporting channel | Operations |
| Site Requirements | Orientations, PPE, work permits, restrictions | Safety |
Deactivate the outgoing provider's access credentials on a defined date and document it.
Personnel: What You Should and Should Not Assume
Caution is needed here. What is generally established in the Federal Labor Law is that article 41 regulates employer substitution and states that it does not affect employment relationships at the company or establishment when its assets are transferred. Whether that provision applies to a change in service providers, and what consequences it would have for the outgoing provider's personnel, depends on the facts and the contract; it is a question for Legal, not a general rule. Do not assume that personnel "transfer" to the new provider, or that they do not.
What you can do without entering that territory:
- Ask the new provider for its own staffing plan for the site: headcount, shifts, supervision, and initial training.
- Require its employees to arrive registered with IMSS and having completed the safety orientations your site requires.
- If you share lists containing names or other personal data, determine with your legal team what information will be shared and under which privacy notice. The Federal Law on the Protection of Personal Data Held by Private Parties (new law published in the DOF on March 20, 2025) sets out rules for transferring personal data; Legal must explain how they apply.
The New Provider: What Must Be Verified
Before week 1, verify the incoming provider (the full steps are in the REPSE verification guide).
- Confirm it appears in the STPS public registry (repse.stps.gob.mx, "Consultar Padrón" [Search Registry]) and that its validity period and authorized services match the service you are contracting. Registration is renewed every three years.
- Confirm the contract is in writing and specifies the purpose of the services and the approximate number of workers (art. 14 of the LFT); the contracting party is jointly and severally liable if the contractor fails to meet its obligations to its workers.
- Compliance opinions from IMSS, SAT, and Infonavit, with visible issue dates. Infonavit states that registration verifies compliance with all three institutions.

4-Week Transition Schedule
- STEP 01
Prepare
Inventory, scope, and access credentials.
- STEP 02
Hand Over
Clear allocation of areas and shifts, without interference.
- STEP 03
Take Over
Documented handover and deactivation of outgoing access credentials.
- STEP 04
Stabilize
Inspections, incidents, and measured adjustments.
Before day 1 (week 0, for matters within your control): documented decision, current contract reviewed by Legal, incoming provider verified and under a signed contract, and start date agreed with both providers.
| Week | Objective | Main Activities | Deliverable |
|---|---|---|---|
| 1. Prepare | Ensure nothing depends on someone's memory | Joint site walkthrough with the new provider; survey of areas, frequencies, and critical zones; inventory of equipment and keys; access arrangements; safety orientation; kickoff meeting with the current provider to set handover dates | Area sheets, signed inventory, access plan |
| 2. Hand Over and Overlap | Operate in parallel with controls | Start of overlap: the new provider handles an agreed portion of the site or shift while the current provider continues with the rest; handover of the corresponding keys and access credentials; on-site training; first joint inspection | Partial handover record, daily log |
| 3. Take Over | Have the new provider handle the entire operation | Transfer of remaining areas; deactivation and replacement of the outgoing provider's access credentials; removal of its supplies with a written record; daily inspections of critical areas | Outgoing provider exit record, updated access credentials |
| 4. Stabilize | Measure and adjust | Incident review; weekly checklist inspection; frequency adjustments; closing meeting with Operations and Procurement; date for the first monthly review | Closeout report, follow-up plan |
About the overlap. Its duration depends on the site size and contract, and the current contract may limit it (for example, if it ends on a fixed date). Define it before signing the new contract, including who pays for what during those days. Measure uncovered areas, incidents per shift, and response time, and set acceptance criteria in week 1.
Common Mistakes
- Giving notice without reading the contract. You could lose the most favorable termination option.
- Not setting a date to deactivate access credentials.
- Starting without a joint walkthrough.
- Not documenting initial conditions. Without photos or an initial inspection, evidence for a later dispute is lost.
- Deciding on price alone.
- Leaving out Operations, the team that experiences the service every day.

An orderly provider change is more like a planned move than a breakup: you read the contract, verify the incoming provider, hand over access credentials and information, operate in parallel, and measure results.
