# HR SaaS Vendor Risk: When Your Leave Management Tool Disappears

> Real stories of HR SaaS tools that shut down, got acquired, or hiked prices, and what they tell you about the cost of depending on a vendor for leave management.

I keep coming back to vendor risk in the self-hosted vs SaaS conversation, and the Lattice news from late 2025 is exactly why.

In November 2025, Lattice told its customers it was sunsetting its HRIS and Payroll products. Payroll access ends on 31 March 2026. HRIS access ends on 31 July 2026. Lattice is a well-funded, recognised brand in HR tech, valued at $3 billion in 2022. None of that mattered to the customers who suddenly had a few months to migrate their employee records elsewhere.

This is the part of the SaaS conversation nobody likes to lead with. When you pick a tool to track who's on holiday next week, you're also signing up for the vendor's roadmap, pricing decisions, and continued existence. That risk is invisible until the day it isn't. I want to walk through some concrete examples from the HR space, because the pattern is more common than people think.

## The Lattice sunset, in context

Lattice didn't shut down. They scaled back. Performance management is staying; the HRIS and Payroll products are going away, and existing customers are being pointed at Workday as a replacement. There's [a writeup from Calamari](https://www.calamari.io/blog/lattice-hris-is-shutting-down-how-to-migrate-without-the-enterprise-price-tag) covering what affected teams need to do, and [Hibob has a piece](https://www.hibob.com/blog/lattice-competitors-hris-alternatives/) on alternatives.

Look at the timing. The HRIS launched in 2024. Less than two years later it's being unwound. If you onboarded onto Lattice HRIS as a small company in early 2024, you spent that time configuring fields, importing employees, and training people on it. Now you're migrating again. None of that work transfers cleanly. That's the cost the pricing page never shows.

## Zenefits, and the limits of funding as a moat

Zenefits is the flagship cautionary tale. Founded in 2013, [valued at $4.5 billion in May 2015 after a $500M round](https://techcrunch.com/2015/05/06/zenefits-rising-hrs-hottest-startup-just-raised-500-million-at-a-4-5-billion-valuation/) led by Fidelity and TPG, with Andreessen Horowitz participating. By 2017 the new CEO had laid off 45% of the workforce. In February 2022 it was sold to TriNet, in what most observers described as a fire sale relative to its peak.

The story doesn't end with the acquisition. In December 2024, TriNet announced it was [sunsetting the standalone Zenefits HRIS plan](https://www.outsail.co/post/trinet-to-lay-off-zenefits-team-and-sunset-standalone-hris-option). The product is now branded TriNet HR Plus, and customers on the original Zenefits offering had to migrate to a more expensive enterprise tier or leave the platform.

$500 million in funding, a $4 billion valuation, a major-name acquirer. None of it guaranteed continuity for the small businesses that built their HR processes around the product.

## UKG Workforce Central: even the enterprise stack ages out

If you assume the small startups are the risky bets and the giants are safe, the UKG story shows the same pattern at enterprise scale. Kronos and Ultimate Software merged into UKG in April 2020. After the merger, UKG announced that Workforce Central, the legacy Kronos product used by enormous organisations including hospital systems and large employers, would be discontinued. The cloud-hosted environment was [shut down on 31 December 2025](https://www.healthcareitleaders.com/blog/ukg-workforce-central-wfc-end-of-life/). On-premises support ends on 31 March 2027.

Customers can migrate to UKG Pro Workforce Management, which is a different product with different ergonomics and a different configuration model. It's not an upgrade. It's a forced rewrite of how your organisation runs payroll and time tracking. Size doesn't insulate you from this kind of decision; it just means more of your people are affected when it lands.

## Acquisitions: the product survives, the product you chose doesn't

Not every story is a shutdown. Sometimes the product keeps running, but it stops being the thing you originally signed up for. CakeHR was a small, focused leave and HR tool until [Sage acquired it in November 2019](https://www.sage.com/investors/investor-downloads/press-releases/2019/11/sage-announces-acquisition-of-cakehr/) and rebranded it to Sage HR a year later. It still exists. The roadmap, pricing, and strategic priorities now belong to a multinational accounting software company.

Timetastic, which I mentioned in [the self-hosted vs SaaS post](/blog/self-hosted-vs-saas-leave-management) as an example of a mature product that's a reasonable choice, was [acquired by The Citation Group in May 2023](https://thecitationgroup.com/news_article/the-citation-group-acquires-timetastic-global-absence-management-software-for-small-and-medium-sized-businesses/). The pricing today is $1.50 per user per month on Standard and $2.50 on Pro, broadly in line with where it was, so nothing dramatic has visibly changed for customers. But the company that owns the roadmap is now a compliance and HR services group, not the original team.

Namely raised over $200 million from Sequoia, True Ventures, and GGV Capital, with a $500 million valuation in 2018. In September 2022 it was [acquired by PrismHR / Vensure](https://www.prismhr.com/press-releases/namely-merges-with-vensure-employer-services-prismhr/), a private equity-backed business. Reviews after the acquisition consistently describe a product that became more rigid and more focused on margin.

Humi, a Canadian HR platform with a Series B behind it, was [acquired by Australian company Employment Hero in January 2025](https://betakit.com/humi-acquired-by-australian-hr-software-company-employment-hero/). The Canadian customers who picked Humi for its local focus are now part of an Australian parent's strategy. The brand is being phased into Employment Hero, retained for existing customers and Quebec.

Fond is a small data point with a layered ending. Y Combinator-backed, [acquired by Reward Gateway in March 2023](https://www.rewardgateway.com/press-releases/reward-gateway-acquires-fond). Reward Gateway itself was acquired by Edenred two months later. If you were a Fond customer in early 2023, you became a Reward Gateway customer, and then an Edenred customer, inside a six-month window.

## Price hikes are vendor risk too

Shutdowns get the attention, but price changes are far more common and just as disruptive when you're locked in.

BambooHR restructured its pricing in 2024. Reports from customers and review sites pointed to roughly 30% increases for affected tiers, plus a $250 minimum monthly charge that hits teams under 25 employees particularly hard. Features that used to be included (payroll, time tracking, benefits administration) moved to paid add-ons.

Gusto raised the base fee on its Simple plan from $40 to $49 in March 2026, an increase of around 23%, with no new features attached. Their EOR plan went from $599 to $699 in the same round. Plus and Premium tiers were left alone, but for the small businesses on Simple, the math changed overnight.

This is the late-stage SaaS pricing pattern. Once a tool has enough customers and enough switching cost, the lever to pull is price. There's nothing you can do about it except migrate, and migration is exactly what the pricing model is betting you won't do.

## What this means for picking a tool

To be fair: SaaS is the right call for plenty of teams. If you don't have a developer who can run Docker, or if you need mobile apps and SSO and integrations from day one, a mature SaaS product is the pragmatic choice. The trade-offs in [the previous post](/blog/self-hosted-vs-saas-leave-management) still hold.

What I am saying is that vendor risk is a real category of cost, and it's the one most teams underweight when comparing options. The pricing page shows you a per-user-per-month number. It doesn't show you the probability that in three years you'll be migrating, on someone else's timeline, to a product you didn't choose. Lattice, Zenefits, UKG, CakeHR, Timetastic, Namely, Humi, Fond. These aren't outliers. They're the normal lifecycle of HR SaaS.

Self-hosting is one way to take that specific category of risk off the table. Nobody can sunset your deployment. Nobody can raise your prices on a Tuesday. You're responsible for keeping the thing running, and that's a real cost. But it's a cost you control.

## Vendor risk is a line item

When you depend on a vendor, you depend on their judgement, their funding situation, their next acquirer, and their pricing roadmap. Most of the time none of this matters. Until it does, and then it matters all at once.

Who's OOO is open source and free to self-host. The source is on [GitHub](https://github.com/igornast/who-is-out-of-office), and the documentation walks you through getting it running with Docker. If you're evaluating options for your team, run the numbers over three years, and factor vendor risk in honestly. It's a cost like any other.
