CIMS — the Cleaning Industry Management Standard — is the credential that distinguishes a BSC that manages operations systematically from one that manages them reactively. It is not a product certification, not a safety certification, and not a government license. It is a management systems audit: a third-party assessor evaluates whether the BSC has documented, implemented, and maintained the management systems that ISSA has defined as the foundation of a professionally operated cleaning company.
For a buyer — a facility manager, an EVS director, a property management company, or a government contracting officer — CIMS certification provides documented third-party evidence that the BSC meets an independently set operational standard. For the BSC, CIMS signals operational maturity to buyers who would otherwise rely on references and site visits to make that assessment.
This article covers what CIMS requires, how the audit process works, what the CIMS-GB (Green Building) variant adds, how CIMS has integrated with GBAC STAR Service, and how to evaluate whether pursuing CIMS makes sense for your operation.
What CIMS evaluates: the six management categories
ISSA's CIMS program evaluates a BSC across six management categories. Each category requires documented evidence — written policies, training records, inspection logs, chemical inventories — not merely verbal assurance.
1. Quality systems. Does the BSC have a documented quality management system? This includes written cleaning specifications, documented inspection programs, and a process for responding to and closing out quality failures. The quality systems category is the one most directly tied to software tools: platforms like CleanTelligent, Janitorial Manager, and Swept generate the timestamped inspection records that serve as evidence for this requirement. See the factual comparison of Swept vs Janitorial Manager vs CleanTelligent for how each platform supports quality documentation.
2. Service delivery. Does the BSC have documented cleaning procedures, production rate standards, and scope-of-work definition processes? This category intersects with ISSA 447 production rate standards — CIMS assessors look for evidence that the BSC uses a recognized production rate framework to determine staffing.
3. Human resources. Does the BSC have documented hiring, training, and performance management processes? This includes new employee orientation, ongoing training records, and a documented process for corrective action. The HR documentation requirement has a compliance overlay: training records for OSHA 29 CFR 1910.1200 Hazard Communication — the requirement that workers be trained on chemical hazards and SDS use — are part of what CIMS assessors review.
4. Health, safety, and environmental responsibility. Does the BSC have documented safety programs? This includes chemical management (SDS documentation and worker access), PPE programs, and incident reporting processes. For BSCs serving healthcare accounts, OSHA 29 CFR 1910.1030 bloodborne pathogen training records are also reviewed. The overlap between this category and GBAC STAR Service requirements is substantial — which is why ISSA merged the programs.
5. Management commitment. Does leadership demonstrate consistent commitment to the management systems? This is evaluated through documentation of leadership review processes, budget allocation for safety and training, and evidence that quality failures result in documented corrective action rather than being ignored.
6. Green building (CIMS-GB add-on). The green building variant adds a sixth evaluated area covering environmental sustainability of cleaning products and protocols. See the CIMS-GB section below.
The audit process
CIMS certification is obtained through a third-party audit conducted by an ISSA-authorized assessor. The process runs in four stages:
Stage 1: Application and readiness assessment. The BSC applies through ISSA's CIMS portal. Before the formal audit, the BSC typically conducts a self-assessment against CIMS criteria to identify documentation gaps. ISSA publishes the CIMS criteria in full; there is no mystery about what will be evaluated.
Stage 2: Document review. The assessor reviews submitted documentation: quality manuals, training records, inspection logs, chemical inventories, safety policies, HR procedures. This review typically happens remotely before any site visit. Documentation that is absent or inadequate at this stage generates a deficiency finding that must be resolved before certification is granted.
Stage 3: On-site assessment. The assessor visits the BSC's office and one or more client accounts to verify that documented procedures are actually being followed. An inspection program documented on paper but never conducted in practice will generate a finding here. A training program listed in a policy but not evidenced by signed training records will also generate a finding.
Stage 4: Certification decision and report. The assessor submits findings to ISSA. If the BSC meets all criteria, CIMS certification is granted for a period of three years. If deficiencies are found, the BSC has a defined period to resolve them before re-assessment.
The audit fee is paid by the BSC to the assessor; ISSA also charges a licensing fee. Both fees vary; verify current fee schedules directly with ISSA at cims.issa.com. CIMS certification is published in ISSA's public directory of certified BSCs, which procurement officers reference directly.
Recertification is required every three years, with a re-audit by an ISSA-authorized assessor. The recertification process verifies that the management systems have been maintained and that changes in company size, service scope, or personnel have been reflected in updated documentation.
CIMS-GB: the green building variant
CIMS-GB adds a green building-specific module to the base CIMS audit. The module evaluates:
- Product certification: whether the BSC uses EPA Safer Choice, Green Seal GS-37, or equivalent third-party certified cleaning products at a defined minimum percentage of purchases
- Documented cleaning protocols for LEED-certified or LEED-pursuing buildings
- Staff competency in green cleaning product use and documentation
CIMS-GB was explicitly designed to support LEED O+M credits for cleaning management programs. Under LEED v4 O+M, a building's cleaning management program could demonstrate compliance partly through a BSC holding CIMS-GB certification. LEED v5, ratified in March 2025, is still finalizing its O+M cleaning credit structure; BSCAI has noted publicly that the LEED v5 O+M framework may change the cleaning prerequisite structure compared to v4. Verify the current LEED v5 O+M credit applicability for CIMS-GB against the USGBC's current reference guide before using CIMS-GB as a selling point for LEED v5 projects specifically.
For BSCs serving building portfolios that include LEED or WELL v2 buildings, CIMS-GB combined with Safer Choice product sourcing covers the primary green cleaning documentation requirements. See Green Seal, EcoLogo, Safer Choice, and CIMS-GB certification pathways for the full product certification landscape.
CIMS and GBAC STAR Service: the merged landscape
In April 2023, ISSA announced the alignment of GBAC STAR Service Accreditation with CIMS. The two programs are now integrated so that a BSC pursuing CIMS certification will find its requirements substantially overlapping with GBAC STAR Service — particularly in the areas of health, safety, and environmental responsibility.
For BSCs deciding which credential to pursue first:
- GBAC STAR Service is the more recognized credential in healthcare, hospitality, and post-pandemic infection control contexts. Its 20 program elements explicitly address cleaning, disinfection, and infection prevention protocols. The GBAC STAR Service Accreditation process covers the program in detail.
- CIMS (without GBAC) is more recognized in commercial office, educational, and property management contexts where management systems documentation — quality systems, HR, service delivery — is the primary buyer concern.
- The combined pathway minimizes duplication: a BSC that pursues CIMS and integrates the GBAC STAR Service requirements simultaneously satisfies both credential requirements with a single documentation build.
For BSCs serving healthcare accounts specifically, also see the ISSA HEHP healthcare environmental hygiene professional certification for the individual worker credentialing that complements CIMS as an organizational credential.
The business case for CIMS certification
The decision to pursue CIMS should rest on market demand, not credential prestige. Three market signals indicate CIMS is worth pursuing:
1. Your target buyer segment requests it. Government contract solicitations, healthcare system RFPs, and large commercial property management companies increasingly include CIMS or an equivalent management systems certification as either a requirement or a scored evaluation factor. If your target clients are not in those segments, CIMS adds less immediate value.
2. Your operational documentation is already 70% of the way there. CIMS is most efficiently pursued when the BSC already has written procedures, training records, and inspection programs — the audit formalizes and validates existing systems. Pursuing CIMS from scratch, without any underlying documentation, is a significant implementation project that can take six months to a year before an audit is feasible.
3. The certification cost is recoverable in won contract value within 12 months. CIMS certification is a marketing tool as much as an operational standard. If your close rate on CIMS-specified RFPs increases by one large account per year at $100,000 in annual revenue, and your audit cost is $5,000 to $10,000, the math works. If CIMS-specified RFPs are rare in your market, the calculation changes.
For BSCs building toward CIMS while also managing bid profitability, the account profitability auditor methodology provides the financial framework for ensuring that accounts won partly on the strength of a CIMS credential are actually priced to deliver margin. The $/sqft benchmarks by facility type article provides pricing context for CIMS-adjacent segments (healthcare, education, government).
At BLS median wages of $17.27 per hour for janitors, per May 2024 OEWS data, loaded to approximately $21 to $22 per hour, CIMS's quality systems documentation also serves a direct operational purpose: inspection records catch service failures before clients notice, and catching failures before a complaint is the single most effective account retention mechanism available. The CIMS documentation requirement and the retention benefit are the same asset.
What to verify yourself
Before pursuing CIMS, verify the following directly:
- Current CIMS criteria and fee schedule: ISSA updates CIMS criteria periodically. Access the current criteria and the current assessor fee schedule directly at cims.issa.com.
- CIMS-GB and LEED v5 O+M credit compatibility: Verify whether CIMS-GB satisfies the current LEED v5 O+M cleaning management credit against the USGBC's published reference guide. Do not rely on the LEED v4 O+M credit structure as a proxy for v5.
- GBAC STAR Service alignment: Confirm the current scope of CIMS / GBAC STAR Service integration at ISSA. The April 2023 announcement aligned the programs, but the specific documentation overlap between the two audits requires verification with ISSA directly.
- Assessor availability and timing: ISSA-authorized assessors are not uniformly available nationwide. Contact ISSA to identify assessors in your region and typical audit scheduling timelines before setting a target certification date.
- Your OSHA training record documentation: Before an audit, verify that your OSHA 1910.1200 HazCom training records, PPE program documentation, and (where applicable) 1910.1030 bloodborne pathogen training records are complete and accessible. These are the most common documentation gaps found in pre-audit self-assessments.
- Directory listing verification: After certification, verify that your CIMS listing appears correctly in ISSA's public directory. Procurement officers search this directory directly.
