Technical Documentation That Ships With Your Product

API references, user guides, SOPs, and knowledge bases — written by technical writers who've shipped docs for SaaS platforms, hardware manufacturers, and regulated industries across North America.

API Reference Documentation

Docs developers actually open during integration — not after they give up

API documentation that's missing one endpoint or one error code is the same as no documentation. We write complete API references with working code examples in every language your users need, authentication flows that don't bury the token format, and error tables with actual recovery instructions — not just HTTP status codes.

  • REST, GraphQL, and webhook documentation from OpenAPI specs or direct engineer interviews
  • Code examples in the 3–4 languages your users actually write
  • Error code tables with root cause and remediation steps
  • Changelog-integrated so version diffs are scannable, not confusing

Full API Reference · 47 endpoints
We'd been shipping features for two years with no external API docs. Docline interviewed our backend team, mapped every endpoint, and delivered a complete reference in 11 days. Our integration support tickets dropped 60% in the first month.

User Guides & In-Product Help

Feature launches that don't generate a wave of "how do I..." support tickets

User guides written for the person who just clicked your new feature at 11pm, not for the person who built it. We cover the flows users actually take, handle the edge cases your support team already knows about, and write for the reading level of someone who's distracted — because they always are.

  • Task-oriented structure: users find the answer in under 30 seconds or the article fails
  • Screenshots and annotated UI captures timed to your feature freeze
  • Integrated with your help center, Notion, or docs-as-code pipeline
  • Includes troubleshooting trees for the 8 questions support gets every week

User Guide · 22 articles · 14-day turnaround
We launched a completely redesigned onboarding flow and needed user docs in 10 days. Docline embedded with our product team, attended QA sessions, and shipped a 22-article guide that our CS team still calls the best we've ever had.

SOPs & Knowledge Bases

Audit-ready process documentation that survives the next re-org

SOPs written for regulated industries carry a different weight than internal wikis. We structure process documents around the decisions they govern — not just the steps — so they hold up under FDA, ISO, SOC 2, and internal audit scrutiny. Knowledge bases organized so the answer to "how does this work" doesn't live in one person's head.

  • SOPs structured to ISO 9001 and FDA 21 CFR Part 11 documentation standards
  • Decision criteria, exception handling, and approval chains documented alongside procedures
  • Knowledge base architecture that survives team turnover and product pivots
  • Version-controlled in your existing system — Confluence, Notion, SharePoint, or Git

SOP Library · 34 procedures · 5-week engagement
We had a SOC 2 audit in six weeks and our process docs were scattered across three tools and four people's heads. Docline ran a structured interview process, built a full SOP library in Confluence, and we passed the audit with zero documentation findings.
