Hiring a PostHog Expert: A No-Nonsense Guide

What does a PostHog expert actually do?

Many people who advertise themselves as “PostHog experts” are developers who can wire events or install SDKs. But that’s not what your business needs. 

Your analytics setup needs to reflect how your business actually thinks and operates. It must speak the same language as your management team, tracking the metrics clean, structured, and directly tied to your goals and actions. It’s not enough to capture clicks and sessions; your tracking has to reflect how your product actually creates value.

So when you hire a PostHog expert, you’re not looking for someone who just “sets it up.” You need someone who can own the entire analytics loop, and understands how growth decisions are made and can connect instrumentation to strategy. To items:

• Instrumentation: Design your event schema, user IDs, properties, and conventions.
• Implementation: Install SDKs (web, mobile, backend), tag events, set up feature flags, experiments, and server-side ingestion.
• Data quality: Deduplicate, validate, and enforce naming standards; set up automated QA.
• Analysis: Funnels, cohorts, retention, paths, session replays; connect findings to growth levers.
• Experimentation: Hypothesis design, metrics, guardrails, exposure rules, and post-test analysis.
• Enablement: Templates, dashboards, training, and documentation so your team doesn’t depend on a single person.

This level of competence will narrow your options. Most “experts” won’t qualify once you look through this lens. But that’s a good thing. The person or team you choose will shape how every future decision gets made. Any investment you make here compounds across product, marketing, and strategy. Done right, this step pays for itself many times over.

When do you need to hire a PostHog expert?

• Not all of your data sources or events are being tracked.
• You can’t trust your numbers (IDs, attribution, or totals don’t reconcile).
• You can’t measure or agree on your marketing’s performance.
• Experiments take weeks to set up or reach significance.
• You have dashboards, but no decisions can be made using them.
• Your PostHog’s cost is skyrocketing but no real value is being created by it.
• You need high quality events sent to your ad pixels.

What skills or qualifications should a PostHog consultant have?

The technical mix you’ll need from a PostHog consultant depends on your stack and goals, but the fundamentals don’t change. Whether you’re instrumenting a SaaS product or running growth experiments, the person handling your analytics needs fluency across code, data, and business context. At minimum, they should be comfortable with the following skill sets:

• Technical: JS/TypeScript for web, at least one backend (Node/Python/Ruby/Go), mobile SDK familiarity, and API/webhook chops.
• Data: Event modeling, schemas, SQL, identity resolution, and warehouse exports.
• Product/Growth: Funnel math, retention curves, test design, north star metrics.
• Ops: Git, CI/CD for tags/config, privacy/compliance, documentation discipline.
• Proof: Case studies with quantified impact and working references.

Tools and buzzwords are easy to list, measurable impact isn’t. A true PostHog expert can show you real case studies with hard metrics and live dashboards, not just talk theory. If they can’t quantify their past results, they won’t be able to quantify yours.

How much does it cost to hire a PostHog expert or consultant?

Pricing depends on complexity (platforms, auth model, data volume), scope (setup-only vs. ongoing), and speed. (And frankly, the quality of the expert most importantly!)

Engagement Type	Typical Scope	Ballpark Fees
Diagnostic + Plan (1–2 weeks)	Audit, tracking plan, risk list, implementation roadmap	$1,500–$3,000
Main Setup (3–6 weeks)	SDKs, 20–60 key events, IDs, QA, core dashboards	$2,500–$5,000
Advanced Customization (4–10 weeks)	Feature flags, data pipelines, warehouse export, Custom features	$2,000 and up
Ongoing (monthly)	Experiments, QA, CRO Analysis, enablement	$2,000–$5,000/mo
Hourly	Ad-hoc support	$100–$250+/hr

If you see “$1k for full setup,” expect missing QA, poor naming, and rework later. They’re not building an analytics system, they’re wiring a few events and hoping it holds. You’ll pay for it later in missing data, broken funnels, and rework.

At 99Ways, most setups fall on the lower end of these ranges, (but always with proper QA, documentation, and growth-ready architecture.)

---

How long does a full PostHog setup usually take?

• Week 0–1: Discovery & Plan — Audit, event schema, success metrics, owners.
• Week 1–3: Implementation — SDKs, server events, identity stitching, initial dashboards.
• Week 3–4: QA & Hardening — Duplicate checks, property validation, regression tests.
• Week 4–6: Experiments & Enablement — Feature flags, test templates, training, docs.

Tight teams with fewer platforms land closer to 3–4 weeks; complex stacks take longer.

---

What deliverables should you expect from a PostHog setup project?

At the end, your team should be able to understand, audit, and extend the PostHog setup. This means you should expect the following outputs:

• Tracking Plan (events, properties, IDs, owners, acceptance criteria)
• Implementation Diff or Guide (PRs/commits or tag manager config)
• QA Artifacts (test cases, screenshot/video proof, validation logs)
• Dashboards (traffic sources, activation, conversion, retention, product KPIs)
• Experiment Templates (metrics, exposure, guardrails, analysis document, CRO plan)
• Runbook & Docs (how to add events, naming standards, governance)
• Handover Session (recorded training + Q&A)

If any of these are missing, you’re buying labor, not outcomes.

---

How do PostHog experts collaborate with marketing, product, and engineering?

• Single owner per metric; no shared ownership of critical numbers.
• Ticketed event requests with acceptance criteria and data dictionary updates.
• Release gating: new features don’t ship without event coverage + QA.
• Weekly analytics sync: review changes, regressions, top insights, upcoming launches.
• Privacy controls: PII policy, hashing, and environment separation (dev/stage/prod).

---

What stacks I can setup PostHog on?

While the answer to this is almost anything online, it’s not bad to go over a list to be sure:

Web: React, Next.js, Vue, Nuxt, Angular, Svelte, plain JS, Webflow, WordPress, Shopify, ClickFunnels, Bubble, Wix, GoHighLevel.
Mobile: iOS (Swift/Obj-C), Android (Kotlin/Java), React Native, Flutter.
Backend/Server: Node/TypeScript, Python (Django/Flask/FastAPI), Ruby on Rails, Go, PHP (Laravel), Java/Spring.
Desktop: Electron, Tauri (via web SDK).
Hosting: PostHog Cloud, or self-host with Docker/Compose/Kubernetes on AWS/GCP/Azure/DigitalOcean.
Data: Export to BigQuery/Snowflake/Redshift; pull from queues/webhooks; enrich with CRM/CDP.

If it runs JS or has an HTTP API, you can instrument it.

---

What’s the difference between a PostHog expert, analytics engineer, and data scientist?

• PostHog expert: Event design → implementation → QA → insights → experiments. Full loop.
• Analytics engineer: Models/DBT/warehouses; less product instrumentation.
• Data scientist: Modeling/experiments/statistics; depends on clean data from the first two.

Hire the PostHog expert to make data exist and be trustworthy; pull in AE/DS as needed.

---

What are the most common mistakes in PostHog setups?

• Transaction inaccuracy (not 100% accurate, revenue amount missing).
• Missing identities (anonymous to authenticated not stitched).
• Traffic sources unreliable (not captured, or details are missing).
• Event bloat (hundreds of low-value events; none tied to decisions).
• Inconsistent naming (Signup, sign_up, userSignUp) → broken funnels.
• No QA (double fires, missing properties, environment leaks).
• Metric confusion (tens of dashboards, but none CEO-friendly).
• Zero governance (no owners, no docs, no review process).

---

How can a PostHog consultant improve conversion tracking and experiments?

• Map the critical path (ad → land → activate → aha → pay).
• Builds dashboards for each use case.
• Find the biggest conversion bottlenecks in user journey.
• Suggest and implement solutions through experiments.
• Use cohorts and feature flags to target the right users and reduce noise.
• Pre-define primary/secondary metrics and minimum detectable effect to avoid p-hacking.
• Build a decision log: each experiment must end with a product or process change.

---

What should you prepare before hiring a PostHog expert?

Most setup delays don’t come from analytics itself but from missing context, unclear goals, unknown systems, or no one owning the merge. A solid prep package helps your consultant move fast and make decisions confidently. Here’s what you should have ready:

• North star + KPIs (how the business wins, and what metrics you want to see).
• Critical user journeys (draw the steps; keep it short).
• Current stack (frameworks, auth, payments, CRM).
• Known data issues (list them).
• Contact list (who managers marketing side, who can merge code, who owns metrics).
• Compliance constraints (PII/PI, regional rules, data residency).

Come with this ready and save ~1–2 weeks of the process.

---

How do you vet or choose the best PostHog expert for your business?

• Ask for before/after metrics and links to live dashboards (scrubbed).
• Look for their past experiences and reviews they’ve got.
• See a sample tracking plan and QA checklist.
• Require owner mapping (who will fix regressions when they happen).
• Ask them: “Once tracking is set up, how do you decide what to test first?” A good expert will link data to business value; not just dashboards.

Anyone can talk a good game about analytics. The ones worth hiring can show you their process, artifacts, and the impact their work had in numbers.

---

What does ongoing collaboration look like after setup?

• Change control for events and properties (schema PRs, versioning).
• Release rituals: pre-release instrumentation review; post-release validation.
• Ongoing conversion analysis: hypotheses generation, anomaly detection, sampling checks, drift alerts.
• Experimenting: running high-quality tests with a documented decision log.
• Quarterly refactors: prune dead events, consolidate properties, refresh dashboards.
