As answered by people managing Postmark and WorkProcedures.
WorkProcedures's answer:
Most SOP tools are either blank-template libraries (download a Word doc, spend days editing it) or generic AI wrappers (ChatGPT with a pretty UI). WorkProcedures sits between them: a curated library of 10,000+ real industry procedures across 35+ sectors grounds every AI generation, so the output uses the terminology, compliance language, and document structure that auditors, trainers, and regulators actually expect - not generic AI boilerplate. Combined with three output detail levels (Standard, Comprehensive, and audit-ready Enterprise with compliance callouts and per-step roles), it's designed for small-to-mid businesses that need ISO 9001, OSHA, or HIPAA-grade documentation without paying for a consultant.
WorkProcedures's answer:
WorkProcedures's answer:
Operations managers, quality leads, HR teams, franchise operators, and consultants at small-to-mid businesses (roughly 10-200 employees) who need professional, audit-ready SOPs but don't have the time or budget for a consultant. Common verticals include medical and veterinary practices, hospitality operators, food safety, cleaning and janitorial services, manufacturing, engineering consultancies, and IT managed service providers. The through-line: they're typically documenting for an audit (ISO 9001, OSHA, HIPAA, state licensing) or standardising procedures across multiple locations and shifts.
WorkProcedures's answer:
WorkProcedures started from watching small-business owners spend entire weekends trying to write SOPs from scratch for basic processes - forklift inspections, new-hire onboarding, patient intake - because the free templates they found online were too generic to use without hours of rewriting. At the same time, AI tools like ChatGPT produced text that sounded plausible but didn't match what a real auditor would expect to see. The idea was to combine the speed of AI with the grounding of a real procedure library, so a small business could get a first draft that's 80% there in under two minutes, then edit the last 20% to fit their specifics, instead of starting from a blank page or a generic template. The platform launched in early 2026 after several months spent curating a library of 10,000+ real industry procedures across 35+ sectors.
WorkProcedures's answer:
WorkProcedures launched in early 2026 and we don't publicly disclose individual customer names at this stage. The current user base spans small-to-mid businesses across these industries:
