AssistNow vs TopBloc: Which Boutique Workday Partner Is Right for You?

The short answer

If you want a fast, predictable, fixed-fee core Workday deployment from a 100% Workday-focused team, TopBloc is an excellent choice. It earned Workday's 2025 Partner of the Year for Business Impact, and it has built its reputation on speed and certainty. If your priority is AI-native delivery, ongoing AI automation after go-live, and keeping your employee and finance data out of third-party AI models, that's where AssistNow is built to win.

Both firms are boutique, fixed-price, and fast. That's table stakes now. The real decision is whether you're buying a clean, proven core deployment (TopBloc's strength) or an AI-native delivery model plus production AI agents and data sovereignty (AssistNow's wedge). This guide compares them honestly, including where TopBloc is the better call.

A genuine word about TopBloc

We're not going to pretend TopBloc is anything other than very good. It is one of the most respected boutique Workday partners in the market for good reasons:

• 100% Workday-certified team. Like us, Workday is the whole business, not one practice among many.
• Fixed-time, fixed-fee deployments. TopBloc removes the open-ended billing risk of time-and-materials, which is exactly what mid-market buyers should want.
• Proven speed on core modules. HCM, Payroll, and Financials deployments are delivered predictably.
• Workday's 2025 Partner of the Year: Business Impact. That's a real, public award that reflects consistent client outcomes.

One factual update worth knowing: TopBloc was acquired by ASGN Incorporated (NYSE: ASGN) in a $340M deal that closed in early 2025 (it had previously been private-equity-owned). It's still an excellent Workday team, but it's now part of a publicly traded company, where AssistNow remains independent and founder-led. For why that distinction matters, see Are there any truly independent Workday boutiques left?.

If you've shortlisted TopBloc, you've shortlisted a strong firm. The question below isn't "who's good." It's "which model fits your priority."

The real differentiator: AI-native delivery and data sovereignty

"Boutique, fixed-price, and fast" is no longer a differentiator. TopBloc offers all three, and so do we. So we won't rest the argument there.

What separates AssistNow is a suite of proprietary AI products that run in production, not in a slide deck:

• Assistly®: conversational HR support that deflects roughly 68% of tickets away from your HR team.
• ValidateIQ™: AI-native data migration that runs on a private, open-weight LLM with zero third-party AI exposure, proven on 1.9M+ journal rows.
• Resolve: AI-powered ITSM for ongoing support.
• ReleaseIQ: automated Workday release management, so the twice-yearly updates stop being a fire drill.

And the part almost no competitor emphasizes: data sovereignty. Our AI runs on a private LLM with a zero-egress posture. Your employee and finance data never touches OpenAI or any other third-party model. For healthcare, financial services, higher ed, and nonprofits, that isn't a nice-to-have. It's often the difference between "yes" and "legal won't approve it."

That's the wedge. TopBloc gives you a proven, fast, fixed-fee core deployment. AssistNow gives you that plus an AI-native delivery model and AI agents that keep working, privately, after go-live.

Best for AssistNow: mid-market organizations that want measurable AI automation during and after implementation, and that need their data to stay private.

Best for TopBloc: companies whose top priority is a fast, predictable, fixed-fee deployment of core Workday modules.

Implementation speed and pricing

Both firms reject the traditional time-and-materials trap. TopBloc's fixed-time/fixed-fee model is one of the clearest in the market and a big reason for its reputation. AssistNow is also fixed-price, with delivery accelerated roughly 40% over traditional consulting because we use our own AI tooling instead of brute-force manual effort.

The honest distinction is how the speed is achieved. TopBloc's speed comes from a disciplined, productized core-deployment playbook. Ours comes from AI doing the heavy lifting: migration, validation, regression testing. That's also why the automation carries into ongoing support.

Unlike most boutiques, AssistNow publishes its prices: fixed-fee packages and AMS (from ~$2,400/mo) are listed transparently on our pricing page. For a quote scoped to your modules and company size, talk to our team.

Ongoing support after go-live

This is where the two models diverge most. TopBloc is best known for getting you live quickly and predictably on core modules. AssistNow is built so that the same AI that accelerated your implementation keeps running afterward: Resolve for AI-driven ITSM and ReleaseIQ for automated release management. Each Workday update cycle is then handled with less manual effort.

If your bigger long-term cost is running Workday rather than standing it up, weigh the ongoing-automation difference carefully.

How to choose

Choose TopBloc if…

• Your top priority is a fast, predictable, fixed-fee deployment of core HCM, Payroll, or Financials.
• You want a firm with a public, recent Workday Partner of the Year award (Business Impact, 2025).
• AI automation and data-residency concerns are secondary to speed-to-go-live.

Choose AssistNow if…

• You want AI agents running in your production Workday — measurable ticket deflection, automated migration, automated releases.
• Data sovereignty matters: your employee/finance data must stay out of third-party AI models (healthcare, financial services, higher ed, nonprofits).
• You care about ongoing AI-automated support, not just the initial deployment.
• You value an independent, founder-led partner whose incentives aren't set by a public parent or PE owner.

Either way, ask both firms the same direct question: "Show me an AI agent you've deployed in a client's production Workday, and tell me exactly where the data is processed." That single question separates real, in-production AI capability from accelerators and marketing.
