What did RSM and BDO announce about AI investment?

RSM US announced a $1 billion three-year AI investment in mid-2025 to target the middle market. BDO USA followed weeks later with its own $1 billion AI commitment. Both firms are explicitly targeting the same $8.3 trillion US middle market — the businesses that small accounting and consulting firms serve as clients. RSM's first major deliverable was Ask Luca, a GenAI tool launched January 8, 2026, giving 4,000+ auditors real-time guidance from RSM's assurance manuals.

Should a small accounting or consulting firm be worried about RSM and BDO's AI investments?

Yes — but strategically, not existentially. RSM and BDO are building AI-native services targeted directly at your clients. The threat is real, particularly on commoditized services like tax prep, audit documentation, and routine compliance work where their AI tools can outpace smaller firms on speed and cost. The response is not to try to out-invest them — it's to compete on what they structurally cannot deliver: deep local knowledge, direct principal attention, and the relationship trust that a firm of thousands cannot replicate for a $5M business.

What is RSM's Ask Luca and who is it for?

Ask Luca is RSM's internal GenAI tool launched January 8, 2026. It gives RSM's 4,000+ auditors real-time, instant guidance from RSM's proprietary assurance manuals — essentially AI-powered access to the firm's entire body of audit methodology, available to every auditor on any engagement. It's an internal tool, not a client-facing product. The significance for small firms: RSM is using AI to make every one of its 4,000 auditors as effective as its most experienced partners. That's the competitive dynamic you're up against on audit and assurance engagements.

What services are most at risk from big firm AI investment?

The highest-risk service categories are those that are high-volume, repeatable, and don't require deep relationship knowledge: standard tax return preparation, routine audit procedures, compliance documentation, basic financial analysis, and research-driven advisory. These are tasks where AI delivers the most dramatic efficiency gains, and where a well-resourced firm can use AI to compete on price or speed. Lower-risk categories: anything requiring deep knowledge of a specific client's situation, industry relationships, regulatory context, or judgment calls that depend on years of working with a particular business.

What are three defensible positions for a small accounting or consulting firm in 2026?

First, specialize by client type — become the firm that knows one industry (construction, healthcare, nonprofit, real estate) better than any regional or national firm could. That depth is structurally un-scalable by a firm chasing the entire middle market. Second, own the principal-access advantage — in a 10-person firm, clients get direct access to the owner or senior partner on every matter; RSM's client gets whoever is assigned to the file that week. Make that contrast explicit in your positioning. Third, use AI on operational work (drafting, research, reconciliation) to free your capacity for the advisory work large firms can't afford to offer at your fee range.

How is RSM using AI to replace entry-level hiring?

RSM's own survey of middle market businesses found that 45% are using AI in place of some entry-level hiring, and 52% anticipate moderate to significant hiring needs over the next 12 months. RSM itself is part of this trend — using AI to automate the work that entry-level associates traditionally handled, concentrating human expertise at the senior levels. The implication for small firms: the talent pyramid is collapsing at the base. A 5-15 person firm may never have had that junior layer to begin with — which means the structural transition happening at large firms is actually less disruptive to your operating model than theirs.

RSM & BDO's $2B AI Bet: Small Firm Playbook

Published: March 14, 2026 | By: The Crossing Report | 9 min read

Summary

RSM US committed $1 billion to AI. BDO USA followed with another $1 billion. Both firms are explicitly targeting the middle market — the same $8.3 trillion segment your accounting or consulting firm likely serves. RSM's first deliverable is already live: Ask Luca, a GenAI tool giving 4,000+ auditors instant access to RSM's entire assurance playbook. The competitive pressure this creates is real. Here's what's actually being built, what it threatens, and the three positions a small firm can defend.

The $2 Billion Signal

In mid-2025, RSM US — the nation's leading provider of audit, tax, and consulting services to the middle market — announced a $1 billion, three-year AI investment. Weeks later, BDO USA announced its own $1 billion AI commitment.

That's $2 billion targeting your clients.

Not enterprise. Not Fortune 500. Middle market — businesses between roughly $10 million and $1 billion in revenue. The businesses that independent accounting and consulting firms have built their practices around.

RSM's own framing makes the intent explicit: this is an investment to "accelerate AI strategy and drive next-level innovative solutions for clients" in the middle market. The same clients who currently pay your retainer.

What's Actually Being Built

RSM's first major AI deliverable is Ask Luca, launched January 8, 2026.

Ask Luca is an internal GenAI tool that gives RSM's 4,000+ auditors real-time guidance from RSM's proprietary assurance manuals. Every auditor at every level, on every engagement, now has instant access to the methodology, precedents, and guidance that RSM's most experienced partners carry in their heads.

Think of it this way: RSM has taken 40 years of audit knowledge, encoded it, and made it available to every person on its team in seconds. The gap between a first-year associate and a 20-year partner just got smaller — on demand, at scale.

RSM's own survey of middle-market businesses reinforces where this is heading: 45% of middle-market firms are already using AI in place of some entry-level hiring. RSM's AI investment isn't just about serving clients better. It's about building a more leverage-efficient firm — fewer junior headcount, AI doing what those people used to do.

BDO's parallel investment follows the same logic: build the AI infrastructure that allows the firm to serve more clients, faster, with fewer people, at a margin structure that smaller competitors can't match.

What This Threatens

Not everything. But some things specifically.

Highest-risk service categories:

Standard tax return preparation — AI can pull a prior-year return, identify changes, flag risk areas, and draft a current-year return faster than any associate. This is already happening at scale.
Routine audit procedures — Automated workpaper preparation, exception flagging, and reconciliation are well within current AI capabilities. Ask Luca is designed to make this work faster and more consistent across RSM's entire workforce.
Compliance documentation — Repetitive, template-driven work (engagement letters, disclosure forms, regulatory filings) is exactly what AI automates first.
Research-driven advisory on common questions — "What's the Section 179 treatment for X?" or "How does the new lease standard affect Y?" are answerable by AI. If that's a meaningful part of what you charge for, that category is under pressure.

The mechanism isn't just competition — it's client expectations.

RSM's survey showed that middle-market companies are cutting entry-level hiring because AI is doing what those people used to do. When your client's internal finance team runs reconciliations in hours using AI, and they know that large firms are deploying AI at scale, they start to notice when their outside advisors still take a week for something they believe AI should handle in a day.

This is not theoretical. It's already the conversation in boardrooms.

What They Cannot Take

Here is the thing about a 4,000-person firm running on AI at scale: it is structurally incapable of delivering what you deliver by default.

1. Direct principal access on every matter.

At RSM, a middle-market client gets a partner on the relationship and a team on the execution. The partner shows up for kickoff and year-end. The rest is staff and managers. That's how a firm of thousands works — it has to be.

At your 10-person firm, the owner is on the file. Every call. Every question. Every judgment call. The client has your cell phone number, your email response time, your direct knowledge of their business built over five years of weekly calls. That level of access is not something a large firm sells — it's not part of their model.

Make it explicit. "At our firm, you work directly with [name], every time." That sentence costs RSM nothing to say and everything to deliver.

2. Deep, narrow industry knowledge.

RSM serves the entire middle market. That breadth is their asset and their liability. No firm can be the deepest practitioner in every industry across 80 offices.

A 10-person firm that serves exclusively construction contractors, or healthcare practices, or SaaS companies, knows the business from the inside in a way a generalist firm cannot replicate at your fee level. You know the bonding requirements, the audit risks specific to their industry, the regulatory nuances that affect their specific clients, the way the deals actually work at their scale.

Specialization is not a consolation prize when the big firms are moving in. It's your primary defense.

3. Flexibility that large firms cannot offer.

A large firm has processes, approval hierarchies, billing minimums, onboarding workflows, and engagement letter standards built for a certain profile of client. A middle-market company with a $25,000 annual accounting engagement fits that profile. A $3M business with a founder who calls when something comes up does not.

Your firm can answer that call on Saturday. Your firm can pivot on a weekend when the client's deal closes unexpectedly. Your firm can give the client 90 minutes on a complex question that a large firm will bill six partner hours to staff and review. That flexibility is a service quality advantage — if you charge appropriately for it and name it clearly.

Three Positions You Can Defend

Position 1: Own a vertical.

Pick one or two industries and go deep. Build the referral network, the specialized knowledge, and the marketing to be the firm for that industry in your market. Position this explicitly: "We work exclusively with dental practices" or "All of our clients are real estate investors." Large firms can't match the depth; smaller firms can't match the specialization of your focus.

Position 2: Lead with principal access.

Stop selling service quality in the abstract and start selling a specific commitment: every client speaks directly to a named partner. Put it in your proposal. Put it on your website. "At [Firm Name], you will speak with [Name] on every matter — not a rotating team." This is a direct contrast with how large firms operate and it resonates with owners who've been burned by the handoff.

Position 3: Use AI on the operational layer to compete on the advisory layer.

The services under most price pressure are the repeatable ones: returns, reconciliations, compliance documents, standard reports. Use AI aggressively on those — not to eliminate them from your service offering, but to free your time for the work that large firms don't offer at your fee level: proactive advisory, business model questions, planning conversations that don't fit cleanly into an engagement letter.

When AI handles your reconciliation workflow, you have 10 extra hours this month. Spend those hours calling five clients to ask what's keeping them up at night. That's the competitive advantage RSM's AI budget cannot buy.

One Thing to Do This Week

Pull up your firm's website or last three proposals. Count how many times you use the word "experienced" or "quality." Now count how many times you name something specific that only your firm delivers — a vertical, a principal-access commitment, a specialty workflow.

If the specific things outnumber the generic ones, you're positioned well for this environment.

If it's the other way around, rewrite your bio page and your standard proposal introduction before the end of this quarter. The version of "we bring decades of experience" that worked in 2020 is not enough in 2026 when RSM has $1 billion in AI and is coming for your clients.

Be more specific than they can afford to be. That's the crossing.
