CharlieHR vs Sling Pricing (2026)

Which one is cheaper?

Sling is the cheaper option, starting at $2/mo vs $20/mo for CharlieHR.

Can I use either one for free?

Sling has a free plan. CharlieHR doesn't — though they do offer a free trial.

How do they charge?

Both use a per-seat model, so the comparison is straightforward — it comes down to features and limits at each price point.

Which one is a better deal?

Depends on what you need. CharlieHR: The headline £5/month rate is a loss-leader hook for very small teams, but that's a 75%-off promo for the first six months only — real pricing (£20 and up) puts them mid-market among UK HR platforms, not a budget play once the discount expires. Sling: At $2-4/user, Sling is priced at the budget end of workforce scheduling software, well below suites like Deputy or When I Work that often start higher. They're clearly going after cost-sensitive hourly-workforce employers — restaurants, retail, healthcare shifts — where per-seat costs add up fast and cheap wins the deal.
