About Opora Supply

What Opora Supply is
Opora Supply is a research and reference site for commercial cleaning operators. It publishes the Opora Field Guide — a free, citation-heavy operational library for building service contractors (BSCs), facility managers, EVS managers, and procurement officers. No products are sold here, and no article is written to sell one.
The commercial cleaning industry generates approximately $112 billion in annual revenue in the United States, per IBISWorld market research data. The sector employs more than 2.2 million building cleaning workers, per BLS Occupational Employment and Wage Statistics. Annual turnover in the sector runs between 75% and 400% depending on account type and geography — a structural condition that makes reliable operational reference material essential and expensive to maintain.
Most of the operator-grade content that exists is either behind a BSCAI membership paywall, sponsored by vendors with a product to sell (CleanLink, CMM), or written for a general audience rather than for someone managing a labor budget. Opora Supply publishes primary-source content that a BSC can actually use on Monday morning.
What we publish
The Field Guide currently includes:
- 372 articles organized across nine content hubs
- 16 free interactive tools — calculators and lookup tables for production rates, bid generation, chemical dilution, PPE selection, VOC compliance, floor care planning, labor burden, and more
- 220+ glossary entries — definitional terms for industry terminology, each cross-linked to relevant articles and tools
- 100 metro wage pages — BLS-sourced janitorial wage and employment data for the top U.S. metropolitan areas
- 51 state licensing pages — contractor licensing requirements for every U.S. state and D.C.

Our editorial standard
Every article published on the Opora Field Guide must cite a primary government or standards-body source for every factual claim. The acceptable primary sources are:
- BLS — U.S. Bureau of Labor Statistics, for wage, employment, and occupational data
- OSHA — for workplace safety regulations, with 29 CFR section citations required
- EPA — for environmental regulations, product registration, and PFAS rulemaking
- NCCI — National Council on Compensation Insurance, for workers' compensation rate data
- ISSA — for production rate standards (specific document and edition required)
- USGBC — U.S. Green Building Council, for LEED requirements
- DOL — U.S. Department of Labor, for wage and hour law
- State regulators — applicable state departments of labor, environmental agencies, and contractor licensing boards
- IWBI, Fitwel, ASHRAE, Census — for wellness building standards and demographic data
Secondary sources (trade publications, industry surveys) are permitted only when no primary source exists and are labeled as secondary in the article. Numbers without verifiable primary sources are not published.
The complete framework governing how articles are sourced, fact-checked, and reviewed is on our Editorial Standards page.
Why this exists
The commercial cleaning industry has a structural information problem. Operators running $500,000 to $5 million in annual revenue need the same quality of sourced operational data that a large enterprise BSC gets from its membership in BSCAI or ISSA. Most of them don't have it. The content that's freely available is either vendor-sponsored (which biases toward product promotion) or too generic to apply to a specific bid, account, or compliance question.
The $112B market figure above represents a sector that includes janitors earning a median of $17.11 per hour as of May 2024, per BLS Occupational Employment and Wage Statistics, operating in a high-turnover environment where institutional knowledge is constantly lost and rebuilt. The operators managing those workers need benchmarks they can cite, frameworks they can apply, and tools they can run numbers through — without a membership fee or a vendor pitch attached.
Opora Supply is free to use. It will remain free.
What we don't do
The following are hard limits, not aspirations:
- No products are sold on this site. Opora Supply is a research and reference resource, not a retailer.
- No paid editorial placement. Vendors do not pay for coverage in the Field Guide. A product's mention in an article is factual, not sponsored.
- No vendor sponsorship of articles. No company pays to shape editorial content in any form.
- No professional advice in regulated domains. We explain statutes, regulations, and compliance processes factually. We do not advise on legal strategy, tax treatment, insurance coverage, or medical matters. Where professional judgment is required, we say so and direct readers to the appropriate licensed professional.
- No fabricated credentials, case studies, or expert quotes. Everything published is sourced and verifiable. We do not invent authority signals.
- No politically loaded content. We do not publish immigration commentary, labor enforcement advocacy, or any content framed around political positions.
The editorial team and process
All content is published under the Opora Editorial Team collective byline. Every article goes through multi-stage review — source pre-mapping, drafting, fact-checking, cross-linking, and editorial approval — before publication. The published work product is the result of that process, not the output of a single author.
The process is documented in full on our Editorial Process page.
