This comparison is written for UK small-business founders, HR leads, and office managers who are evaluating CharlieHR and Treegarden at the same time, typically because the company is outgrowing spreadsheets and needs to consolidate HR admin, leave management, and hiring into fewer tools. The central difference is one of starting point: CharlieHR leads with core HR and treats recruitment as an optional add-on via third-party integrations, while Treegarden leads with its applicant tracking system and treats HR as a module you can add when hiring stabilises. Which direction makes sense depends almost entirely on where your operational pain sits today.
About Treegarden and CharlieHR
CharlieHR is a UK-focused HR platform founded to serve small and growing companies that want a clean, simple alternative to legacy HRIS tools. Its positioning has consistently centred on making HR accessible to non-specialists: founders who double as HR managers, office managers handling people ops alongside other responsibilities, and small HR teams without a dedicated systems administrator. The platform covers employee records, leave and time-off management, structured onboarding workflows, performance reviews (including 360-degree feedback and one-on-one templates), engagement surveys, and perks management. CharlieHR's strength is the depth and finish of these HR admin features, and its Slack integration, which surfaces absence notifications and leave approvals directly in team channels, is frequently cited in user reviews as a daily-use differentiator. As of mid-2026 CharlieHR has over 37 verified reviews on Capterra with a 4.7 out of 5 rating, and 54 reviews on G2, with reviewers consistently highlighting ease of use and responsive support. The platform is built primarily for the UK market; global compliance features, non-UK public holiday calendars, and multi-jurisdiction payroll are not native strengths.
Critically for buyers comparing it to Treegarden, CharlieHR does not include a built-in applicant tracking system. Recruitment functionality is available as an add-on, and for teams with active hiring programmes the platform relies on integrations with third-party ATS tools such as Teamtailor and Workable to sync candidate data into the HR record. This means companies that need both HR admin and a structured hiring pipeline will typically pay for two tools, or pay a premium for CharlieHR's recruitment add-on on top of the core HR subscription.
Treegarden is an ATS-first platform with a built-in HR module, serving UK and broader EMEA companies. Its recruitment suite covers job posting with multi-board distribution, a structured candidate pipeline, interview scheduling, offer management, and source attribution reporting. The HR module adds employee records, PTO management, document storage, and onboarding workflows. Treegarden's Edera AI layer provides ethical candidate ranking, automated screening question generation, and interview question recommendations. UK-specific compliance is built in: UK GDPR right-to-erasure workflows, Right-to-Work check prompts, and IR35 contractor classification flags are part of the product rather than bolt-ons. Pricing is flat-rate by active job slots rather than per employee, which means costs are more predictable as the team headcount grows.

| Reporting and analytics | Source-of-hire reporting, pipeline conversion, time-to-hire, offer acceptance rate, and HR metrics dashboard | HR reporting on headcount, leave balances, and performance review completion; recruitment analytics depend on connected ATS |

Pricing: Treegarden vs CharlieHR
CharlieHR's pricing is structured on a per-employee, per-month basis with tiered brackets based on team size. According to pricing data aggregated on G2 and Capterra (reviewed June 2026), the platform has four pricing editions ranging from approximately £5 to £179 per month. The entry tier serves very small teams of one to four people and is priced at around £5/month; costs scale as headcount increases through successive brackets. Importantly, CharlieHR's publicly listed pricing covers the core HR platform, leave management, onboarding, performance reviews, employee records, and engagement surveys. The recruitment module (which relies on integrations rather than a native ATS) is an add-on, meaning teams that need both HR admin and a structured hiring workflow will need to budget for the CharlieHR subscription plus any connected ATS licence separately. CharlieHR does not publicly list a price for the recruitment add-on; buyers will need to request a quote. CharlieHR's per-employee model is cost-effective at very low headcounts (under 15 employees) but the monthly cost grows linearly as the team scales, and the absence of a native ATS means a separate recruitment tool cost must be factored in from day one if hiring is ongoing.
Treegarden uses a flat monthly rate anchored to active job slots rather than employee headcount. This model is deliberately designed for companies that hire in waves, a retailer filling seasonal roles, a tech startup running three open positions simultaneously, or a professional services firm with a consistent but moderate hiring pace. Recruiter seats are included without a per-user surcharge. A free trial is available without requiring a credit card. Because costs are not tied to employee count, Treegarden's total cost of ownership becomes increasingly favourable relative to per-seat models as the company grows past 20-30 employees. The built-in HR module avoids the need for a separate HR platform during the early hiring phase, and buyers who want deeper HR admin functionality can add the HR module rather than paying for an entirely separate product.

When to choose CharlieHR vs Treegarden
Choose CharlieHR if: Your primary problem is HR administration for an existing team and hiring is infrequent or handled informally. CharlieHR is genuinely strong at what it does: the leave management system is flexible and supports custom company-specific leave types with delegated approval; the performance review module supports multiple review formats and keeps a structured archive; the onboarding workflow covers document collection, task assignment, and access to company information in a way that works without HR expertise to configure. The Slack integration is one of the more complete in the UK SMB HR market, surfacing daily absence summaries and leave approval requests directly in team channels. If your company is UK-based, has under 50 employees, hires fewer than four or five people per year, and needs to professionalise its HR admin layer, CharlieHR is a credible, well-reviewed choice. Its 4.7/5 rating on Capterra across 37 verified reviews and strong presence on G2 with 54 reviews reflects genuinely satisfied customers in this profile.
Choose Treegarden if: Hiring is a recurring business activity rather than an occasional event. If you are posting to multiple job boards, managing tens or hundreds of applicants per role, scheduling interview panels, and tracking source-of-hire data, you need a purpose-built ATS, not an HR platform with a recruitment add-on bolted on via a third-party integration. Treegarden's flat pricing means the cost does not penalise you for growing headcount, which is a structural advantage once you exceed 20-25 employees. The built-in Edera AI layer for candidate ranking and ethical screening is a meaningful differentiation point in a UK market increasingly focused on bias reduction in hiring. UK GDPR, Right-to-Work, and IR35 compliance features are native rather than requiring external configuration. Companies with international hiring or plans to expand outside the UK will also find Treegarden's multi-jurisdiction capability more aligned with their trajectory than CharlieHR's UK-centric positioning.
How we evaluated CharlieHR and Treegarden
This comparison was compiled by the Treegarden product and HR operations team in June 2026. The evaluation drew on the following public sources: CharlieHR's product overview page at charliehr.com/product, CharlieHR's pricing data as aggregated by Capterra (capterra.com) and G2 (g2.com), both reviewed on 8 June 2026, and third-party review analysis from Thrivea's CharlieHR review and SelectHub's feature breakdown. We reviewed all available Capterra reviews for CharlieHR (37 verified reviews as of June 2026) with particular attention to negative reviews, which surface operational friction that positive summaries obscure. The same approach was applied to G2 (54 reviews).
The buyer profile this comparison is written for is a UK-based company with 10-75 employees that is evaluating its first dedicated HR or ATS platform, has some ongoing hiring activity (three or more roles per year), and needs to decide whether to solve HR admin or recruitment pipeline management first. We have been transparent where CharlieHR leads Treegarden, specifically in the depth and finish of its core HR admin module and the breadth of its Slack integration. We have noted where CharlieHR's architecture requires additional spend on a third-party ATS for companies with active hiring. This comparison does not cover enterprise platforms (Workday, SAP SuccessFactors, Oracle HCM) which sit outside the budget and complexity range of the buyer profile described above. Pricing figures quoted reflect publicly available data at the time of writing; always verify at evaluation as pricing changes.
Frequently asked questions
Does CharlieHR have a built-in ATS?
No. CharlieHR does not include a native applicant tracking system as part of its core product. Recruitment functionality is available as an add-on that relies on integrations with third-party ATS platforms such as Teamtailor and Workable. Companies that need structured hiring pipeline management alongside HR admin should factor in the cost of a separate ATS licence or evaluate whether Treegarden's combined ATS-plus-HR approach is more cost-effective for their hiring volume.
How does CharlieHR pricing compare to Treegarden at 25 employees?
CharlieHR charges on a per-employee basis with tiered brackets; at 25 employees the monthly cost depends on the pricing tier applicable to that headcount, with editions ranging from roughly £5 to £179/month across the full range. Treegarden uses a flat monthly rate by active job slots, so the cost does not increase as headcount grows. Buyers with more than 20 employees and active hiring will typically find Treegarden's total cost of ownership more predictable, especially when accounting for the fact that CharlieHR users also need to budget for a separate ATS tool. Always verify both at the time of evaluation as pricing changes.
What are CharlieHR's strongest features according to user reviews?
According to verified reviews on Capterra (4.7/5 from 37 reviews) and G2 (54 reviews) reviewed in June 2026, CharlieHR's most consistently praised features are its leave management and holiday booking interface, its Slack integration for daily absence notifications and leave approvals, the ease of initial setup, and the responsiveness of the customer support team. Reviewers describe it as genuinely accessible to non-HR specialists, which aligns with its positioning for founder-led and small-team use cases.
Can Treegarden replace CharlieHR for HR admin as well as recruitment?
Yes, with the HR module enabled. Treegarden's HR module covers PTO and leave management, employee document storage, onboarding task workflows, and performance management. For companies whose primary pain is recruitment pipeline management, starting with Treegarden ATS and adding the HR module later is a common deployment pattern. Companies whose primary pain is HR admin for an existing stable team and who hire fewer than three or four people per year may find CharlieHR's HR feature depth a better fit in the near term.
Is CharlieHR suitable for companies outside the UK?
CharlieHR is built primarily for the UK market. Reviewers and analysts note that global compliance features, non-UK public holiday calendars, multi-jurisdiction labour law enforcement, and international payroll, are not native strengths of the platform. Companies with employees in multiple countries or active plans to hire internationally will likely find the platform constraining. Treegarden's multi-jurisdiction capability and EMEA positioning make it a stronger fit for companies with cross-border hiring or expansion plans.
