If your company offers a 401(k) through Sentinel, keeping contribution data in sync with payroll shouldn’t mean re-keying numbers every pay period. The Sentinel Netchex relationship connects retirement plan administration with payroll, so employers spend less time reconciling data by hand and more time supporting their people’s long-term financial security.
Here’s what Sentinel is, what Netchex is, and why companies that use both together get a simpler, more reliable retirement benefits process.
What Is Sentinel?
Sentinel provides retirement plan solutions designed to help employers manage benefits while supporting employees’ long-term financial security. As a 401(k) wholesaler, Sentinel works with employers across industries to help them offer and administer retirement plans that employees can count on.
What Is Netchex?
Netchex is a payroll and HR platform built for mid-market businesses with lean HR teams and hourly or deskless workforces. Instead of stitching together separate systems for payroll, time, HR, and benefits, Netchex brings them into one platform backed by real support, so HR teams spend less time on data entry and more time on their people.
How the Sentinel Netchex Integration Works
Netchex works with Sentinel as a retirement plan partner, helping companies offer and manage 401(k) benefits alongside their payroll and HR operations. Rather than treating retirement plan administration as a separate, disconnected process, Netchex’s relationship with Sentinel is designed to support employers who want their payroll provider and their retirement plan provider working toward the same goal: accurate, well-administered benefits for employees. In practice, this works as a secure, two-way API integration processed through Netchex’s Payroll Integrations connection: payroll data, employee contributions, and eligibility details sync automatically between Netchex and Sentinel, cutting down on manual entry and helping keep contribution records accurate and audit-ready.
- Netchex helps employers offer Sentinel retirement plans as part of a broader benefits strategy.
- Payroll and retirement plan administration work together to support accurate, ongoing plan management.
- Employers get support from both Netchex and Sentinel as their retirement benefits needs evolve.
Why Netchex Is the Best Payroll and HR Solution for Companies That Use Sentinel
Companies already working with Sentinel don’t need to choose between a dependable retirement plan provider and a strong payroll and HR platform. Pairing Sentinel with Netchex means your team gets a payroll partner who understands that retirement benefits are part of the bigger picture, not an afterthought bolted onto pay processing.
Beyond the relationship with Sentinel itself, Netchex is built to be the strongest payroll and HR partner for companies like yours. Netchex is ranked #1 on G2 for service, with a 98% customer satisfaction score and 90% of support calls answered by a real, US-based person in under a minute. That’s the difference between a vendor that simply points you toward Sentinel and a partner that actually backs up your retirement benefits strategy with real support.
That combination of dependable service and genuine partnership is why the average Netchex customer stays for 10 or more years, and why companies offering Sentinel retirement plans choose Netchex as their payroll and HR system of record.
