Justworks is a PEO and HR platform that bundles payroll, benefits, compliance, and HR support for growing businesses — but its leave management module is one piece of a comprehensive suite with per-employee pricing and PEO services you may not need.
If your team uses Justworks mainly for leave tracking, you are paying for PEO services, benefits administration, and compliance support you never use. The most common reasons teams look for a Justworks alternative come down to cost, the PEO model that bundles services beyond what you need, and the portal-centric experience that lacks modern chat integrations.
Key Takeaways
- Justworks is a PEO/HR platform — leave management is one module in a comprehensive suite.
- Per-employee pricing with service bundles — costs include PEO services you may not need.
- Leave Balance offers the best value — $10/month flat rate with Slack and Teams integration.
- No native Slack or Teams integration — employees must use the Justworks portal.
- PEO model complexity — the co-employment model involves more than a typical software subscription.
Why Teams Look for Justworks Alternatives for Leave Management
Justworks positions itself as a simpler, more affordable PEO for startups and growing businesses. Its transparent pricing and user-friendly interface set it apart from traditional PEOs.
But many teams that adopted Justworks primarily use it for leave management and basic HR. The leave module covers standard requests and approvals, but teams report several pain points:
- Portal-centric experience — employees must log into the Justworks portal to request leave, creating friction in teams that work in Slack or Microsoft Teams
- Per-employee pricing with service bundles — you pay for PEO services, benefits, and compliance even if you only use leave management
- No native Slack or Teams integration — Justworks lacks full in-chat leave request and approval workflows
- Leave features are basic — as a PEO, Justworks’ leave management is functional but not as configurable as dedicated leave tools
- PEO model lock-in — switching away from Justworks may affect benefits and compliance arrangements
What to Look for in a Justworks Alternative
Key criteria for US businesses:
- Pricing model — flat-rate vs per-employee, and what that means at 20, 50, or 100 employees
- Leave policy flexibility — can you configure PTO, sick leave, FMLA tracking, and custom policies?
- Integrations — does it work with Slack, Microsoft Teams, your payroll provider, or your HRIS?
- Setup time — can you be operational in hours, or does it take weeks?
- Scope — do you need a full PEO, or is dedicated leave management enough?
With that framework in mind, here are the six best alternatives to Justworks for leave management in 2026.
1. Leave Balance — Best Overall Alternative for Leave-Only Teams
Leave Balance is a dedicated leave management tool built for teams that need leave tracking without the complexity of a PEO or HR platform. It is the only flat-rate leave management tool with native Slack and Microsoft Teams integration.
Pricing
| Plan | Price |
|---|---|
| Monthly | $10/month (flat) |
| Annual | $100/year ($8.33/mo) |
That price covers unlimited employees and unlimited leave policies. No per-seat fees, no minimum spend, no hidden charges. A 50-person team pays $10 per month — the same as a 200-person team.
For comparison, the same 50-person team on Justworks pays approximately $300 to $500 per month depending on services selected.
Key Features
- Slack and Microsoft Teams integration — employees request leave, managers approve, and balances update without leaving the chat app
- Unlimited custom leave policies — configure PTO, sick leave, FMLA tracking, parental leave, and any custom entitlements
- Team calendar — real-time visibility into who is off today, this week, or any date range
- Analytics and reporting — leave trends, utilisation rates, and exportable data for payroll
- Multi-country support — manage leave across the US and other regions from one account
- 15-minute setup — connect Slack or Teams, add employees, configure policies, and go
Why It Is the Top Pick
For US SMBs that already have payroll and HR sorted and primarily need leave tracking, Leave Balance covers the core requirement at a fraction of Justworks’ cost. The Slack and Teams integration means employees actually use it without friction, and flat-rate pricing means your software bill does not grow with every new hire.
Leave Balance does not include payroll processing, PEO services, benefits administration, or compliance support. If you need those capabilities, Justworks or a similar platform is more appropriate. But for teams that mainly need leave management, it is the most cost-effective option on the US market.
Best for: Office-based teams of 10 to 200 employees that use Slack or Microsoft Teams and want dedicated leave management without paying for a PEO.
2. Gusto — Best for US SMBs That Need Payroll + Leave Together
Gusto is a US-focused payroll and HR platform popular with small businesses. It covers payroll, benefits, hiring, and basic leave management.
Pricing
| Plan | Price |
|---|---|
| Simple | $40/mo + $6/person |
| Plus | $80/mo + $12/person |
| Premium | $180/mo + $22/person |
For a 30-person team on the Plus plan, approximately $440 per month.
Key Features
- Full-service payroll with tax filing
- Benefits administration
- Basic leave management and PTO tracking
- Hiring and onboarding tools
Limitations
Gusto’s leave management is basic — it lacks the configurability, reporting depth, and Slack/Teams workflow integration of dedicated tools.
Best for: Very small US businesses (under 25 employees) that need payroll and basic leave management.
3. ADP — Best for Companies Wanting a Large Payroll Provider
ADP is the largest payroll and HR services provider in the US. Its HR modules include leave management as part of broader payroll and workforce management suites.
Pricing
| Team Size | Estimated Cost (USD) |
|---|---|
| 10 employees | $100–200/mo (est.) |
| 30 employees | $200–400/mo |
| 50 employees | $350–600/mo |
| 100 employees | Custom pricing |
Key Features
- Full-service payroll
- Leave management as part of HR modules
- Benefits administration
- Compliance and tax filing
Limitations
ADP’s leave management is an add-on to its payroll platform. The interface is dated, and there is no native Slack or Teams integration for leave workflows.
Best for: Companies that want a large, established payroll provider with integrated HR modules.
4. BambooHR — Best for Growing Teams Needing a Full HRIS
BambooHR covers leave management, recruiting, onboarding, performance management, and payroll — but its pricing starts at a $250/month minimum.
Pricing
| Team Size | Estimated Cost (USD) |
|---|---|
| 10 employees | $250/mo (minimum) |
| 30 employees | $300–500/mo |
| 50 employees | $500–800/mo |
| 100 employees | $800–1,500/mo |
Key Features
- Leave management with configurable policies
- Recruiting and applicant tracking
- Onboarding and offboarding workflows
- Performance management
Limitations
BambooHR’s $250/month minimum makes it expensive for small teams. Pricing scales with headcount.
Best for: Growing US companies (30 to 200 employees) that need a full HRIS with leave management as one component.
5. Calamari — Best for Teams Needing Time Tracking Integration
Calamari offers both leave tracking and clock-in/clock-out time tracking.
Pricing
| Plan | Price |
|---|---|
| Leave Management | $3/user/mo |
| Leave + Time | $5/user/mo |
Minimum 10-user purchase. For a 30-person team, approximately $150 per month.
Key Features
- Leave request and approval workflows
- Time tracking with clock-in/clock-out
- Team calendar and absence reports
- Integration with Slack, Google Workspace, and Microsoft 365
Limitations
Calamari’s 10-user minimum means small teams pay for unused seats. The Slack integration handles notifications but not full in-chat workflows.
Best for: Teams that need both leave management and basic time tracking in a single tool.
6. Vacation Tracker — Best for Global, Remote-First Teams
Vacation Tracker is a Slack and Teams-native leave tracker popular with distributed, remote-first teams.
Pricing
| Plan | Price |
|---|---|
| Core | USD $2/user/mo ($50 min) |
| Complete | USD $4/user/mo ($100 min) |
For a 30-person team on the Complete plan, approximately $120 per month.
Key Features
- Native Slack and Microsoft Teams integration for requests and approvals
- Team calendar and absence visibility
- Custom leave policies and accrual rules
- Multi-location support for distributed teams
Limitations
Vacation Tracker’s per-user pricing with minimums makes it more expensive than Leave Balance at every team size.
Best for: Globally distributed, remote-first teams that do not need US-specific compliance features.
Pricing Comparison at a Glance
| Tool | 50-Person Monthly Cost | Pricing Model |
|---|---|---|
| Leave Balance | $10/mo | Flat rate, unlimited users |
| Vacation Tracker | $200/mo | Per user + minimum |
| Calamari | $250/mo | Per user, 10-user min |

| BambooHR | $500–800/mo | Per employee, $250 min |
| Justworks | $300–500/mo (est.) | Per employee + services |

Frequently Asked Questions
Can I migrate my leave data from Justworks?
Most teams export their current leave balances from Justworks and set starting balances in the new tool. Leave Balance supports bulk employee onboarding via CSV upload, which makes migration straightforward.
Do I still need payroll software if I switch to a leave-only tool?
Yes. Dedicated leave management tools like Leave Balance handle leave tracking, not payroll processing. You would continue using Justworks payroll, ADP, Gusto, or your existing payroll provider for pay runs and tax filings. Leave Balance exports leave data for payroll integration.
How does flat-rate pricing work as my team grows?
Leave Balance costs $10 per month regardless of whether you have 10 or 200 employees. There are no tier thresholds, no per-seat charges, and no minimum spend requirements. Your cost stays the same as you hire.
Does Leave Balance support FMLA tracking?
Leave Balance supports configurable leave policies that can be set up to track FMLA-eligible leave types. You define the policies, accrual rules, and entitlements. For FMLA eligibility determination and compliance reporting, you would use your HRIS or a dedicated compliance tool alongside Leave Balance.
The Bottom Line
Justworks is a solid PEO and HR platform for startups and growing businesses, and for teams that genuinely need PEO services — benefits, compliance, and HR support bundled together — it delivers real value. But if your team primarily uses Justworks for leave management, you are likely overpaying for services you do not use.
For most office-based SMBs, Leave Balance offers the best combination of pricing, features, and daily usability — $10/month flat, Slack and Teams integration, and a setup that takes 15 minutes instead of weeks.
Try Leave Balance free for 14 days — no credit card required — and see whether it covers what your team actually needs. Most teams know within the first week.
