Start AI Transformation in Finance: The 90‑Day Plan, Team, and Tech You Need

To start AI transformation in finance, you need a quantified value thesis, a prioritized use‑case shortlist, minimal viable data and controls, a small cross‑functional squad, an auditable AI platform (or AI Workers), and a 90‑day execution plan with governance gates and ROI metrics tied to close, cash, and compliance.

Finance is moving fast: 58% of finance functions now use AI, up 21 points year over year, according to Gartner. Yet many transformations stall before value lands in the P&L. The gap isn’t vision—it’s orchestration: scattered pilots, unclear ownership, shaky data, and no line of sight to audit and ROI. The good news: you don’t need a moonshot. You need a crisp plan that connects business outcomes to AI execution and control.

This guide gives Finance Transformation Managers the playbook: what to do first, who to involve, the minimum data and controls required, how to select platforms and AI Workers, and a 90‑day roadmap to ship results. Along the way, we’ll anchor to proven research—from Deloitte on scenario planning and agentic AI to PwC on Responsible AI in finance—and introduce a pragmatic model that turns pilots into production. You already have what it takes. Let’s put it to work.

The real barriers to starting AI in finance (and why they persist)

The biggest blockers to AI in finance are scattered priorities, weak data readiness, unclear ownership, and fear of audit exposure—more than lack of tools.

If you’ve kicked off “experiments” that never scaled, you’re not alone. Typical patterns look like this: a dozen shiny proofs-of-concept, each chasing a different KPI; siloed data that’s “not perfect enough” to start; overreliance on IT bandwidth; and risk teams rightly asking, “How will this survive SOX and external audit?” Gartner finds the top challenges are data quality/availability and low data literacy/skills—issues that don’t vanish with more pilots. Meanwhile, Deloitte reports finance leaders are ramping scenario planning frequency and AI investment, but ROI lags when teams can’t bridge pilots to embedded, agentic execution.

Under pressure to close faster, forecast better, and cut cost-to-serve, finance often defaults to “do more with less.” That mindset breeds scarcity tactics—long business cases, tooling detours, and stalled value. The shift is “Do More With More”: concentrate your first 90 days on two measurable processes (e.g., close-to-report, AP exceptions), stand up minimal viable data and controls, and deploy AI to do real work with human oversight. When the team sees days shaved off close and cash collected sooner—with audit artifacts maintained—momentum compounds across the finance value chain.

How to prioritize high‑ROI finance AI use cases

You prioritize AI use cases by tying them to value drivers—close speed, cash, cost, and compliance—and selecting processes with structured data and frequent volume.

What AI use cases in finance show ROI in 90 days?

The fastest paybacks typically come from record-to-report and transaction-heavy areas with repeatable rules plus exceptions: period-end reconciliations, PBC list management, AP/AR exception handling, anomaly detection, spend classification, variance commentary drafts, and rolling forecast refreshes. For inspiration, explore pragmatic patterns in 25 Examples of AI in Finance and how AI Workers can execute multi‑step tasks end‑to‑end.

How do you score and pick the first two use cases?

Score candidates on impact (hours reclaimed, cycle time reduced, error risk lowered), feasibility (data availability, rule clarity, system access), and auditability (evidence trail, approvals). Pick one “speed win” (e.g., close accelerators) and one “cash win” (e.g., collections prioritization). Set target metrics: -30–50% manual hours, -2–3 days to close, +10–20% forecast refresh cadence, -25–40% exception backlog.

How do you build the finance AI business case?

Build a one‑page value thesis per use case: baseline current effort and KPIs; size benefits in hours and working capital; list control points; define human-in-the-loop; and specify measurement methods (time-stamped logs, exception rates, cycle times). Tie savings to real levers—deferred hiring, contractor reduction, faster cash application—not abstract “efficiency.”

How to get your data and controls AI‑ready (without boiling the ocean)

You get AI‑ready by enabling minimal viable data access and embedding Responsible AI controls—data lineage, human review, and audit evidence—into each use case.

What minimum data do you need to start?

You need access to the narrow datasets that power your first two processes: e.g., GL balances, trial balance exports, subledger transactions, vendor/customer masters, aging reports, and policy docs. Create a lightweight “sufficient version of truth” slice—don’t wait for perfect warehouses. Gartner recommends pragmatic decision-ready data over chasing a single perfect truth; align on a canonical extract per use case and document lineage.

How do you align AI with SOX/ICFR and Responsible AI?

You align by mapping each AI step to existing internal controls, adding human validation at judgment points, and capturing artifacts. PwC advises three actions: establish data integrity (source validation, lineage), verify outputs with structured human review (right-sized for risk), and govern third‑party AI dependencies (SOC reports plus AI‑specific risks). For each use case, define preparer/reviewer roles, required evidence (input files, prompts, outputs, approvals), and exception escalation.

What governance is “just enough” to move fast safely?

Stand up a light Finance AI Working Group (controller, risk/IT, FTM, process owner) that meets weekly for change control on prompts, models, and connectors. Use a simple RACI, a use case register, and a two‑gate approach: Gate 1 (pilot sign‑off) confirms controls and metrics; Gate 2 (production) confirms performance, evidence capture, and rollback plans. Keep it lean; expand only as scale demands.

How to staff a small‑but‑mighty finance AI squad

You staff with four core roles—process owner, AI product lead, data steward, and AI Worker supervisor—and transient platform help to connect systems and secure access.

What roles do you actually need on day one?

Start with: (1) Process Owner (e.g., R2R, O2C) who defines “done” and owns KPIs; (2) AI Product Lead (your transformation lieutenants) who designs workflows, prompts, and acceptance tests; (3) Data Steward who secures extracts, maps lineage, and validates quality; (4) AI Worker Supervisor who runs daily oversight, handles exceptions, and signs off on outputs. Add light-touch platform/IT support for SSO, data connectors, and security reviews.

How do you upskill the team quickly?

Teach prompt design for finance artifacts (recons, memos, variance narratives), evidence capture for audit, and exception triage. Institute “pair‑ops”: the product lead pairs with the process owner weekly to refine prompts and guardrails, while the supervisor pairs with analysts to codify edge cases. Adopt the simple mantra: If you can describe it, we can build it—and we can measure it.

How do you manage change and confidence?

Shift the narrative from replacement to empowerment: AI Workers clear the grunt work so analysts can analyze. Publish a visible scoreboard: hours returned, days to close improved, exceptions auto‑resolved, audit exceptions avoided. Celebrate reviewers’ decisions as value, not friction.

How to choose platforms and AI Workers that plug into your ERP

You choose tech that integrates with your ERP/finance stack, enforces controls, supports human‑in‑the‑loop, and produces an audit trail while doing real multi‑step work.

What criteria matter for finance platforms and AI Workers?

Prioritize: ERP/ledger integrations (SAP, Oracle, Workday), secure connectors, data residency, role‑based access, prompt governance, versioning, and evidence logging. Require human-in-the-loop checkpoints and reversible actions. Favor solutions that execute multi‑step processes over “copilots” that only suggest. For a primer on why execution matters, read AI Workers: The Next Leap in Enterprise Productivity and the shift from RPA to AI Workers.

Build vs. buy vs. employ AI Workers?

Build when you have unique workflows and strong internal platform talent; buy when you need hardened compliance and integrations fast; employ AI Workers when you want configurable “digital colleagues” that you can onboard, supervise, and measure like staff. Many teams blend: a governed platform plus purpose‑built AI Workers for close, AP exceptions, or investment reporting (see how in How to Generate Investment Reports with AI).

How do you verify vendor claims?

Insist on a 2–4 week pilot with your live data, predefined metrics, and audit artifacts produced automatically. Require red‑team tests on edge cases and confirm rollback. No vague demos—ship evidence.

A 90‑day execution plan to start AI transformation in finance

You deliver value in 90 days by launching two controlled use cases with clear metrics, minimal data slices, and weekly governance, then scaling the playbook.

Days 0–14: Align, baseline, and prepare

Pick two use cases (speed + cash). Baseline KPIs (hours, cycle time, exceptions, working capital). Secure data extracts and system access. Draft control maps and acceptance criteria. Stand up your AI squad and working group. Socialize the scoreboard.

Days 15–45: Build, validate, and pilot with humans in the loop

Configure workflows and AI Workers; connect data; codify prompts and edge‑case playbooks. Run daily cycles with reviewers approving outputs. Capture artifacts (inputs, prompts, outputs, approvals) automatically. Track metrics publicly. Gate 1 sign‑off when targets trend and controls hold.

Days 46–75: Move to controlled production and expand coverage

Promote to production with agreed thresholds (e.g., 80–90% auto‑resolution on defined cases). Increase volume, shrink manual touch on routine items, and keep reviewers on judgment items. Add one incremental scenario per week. Gate 2 sign‑off when thresholds stabilize and audit evidence is complete.

Days 76–90: Prove ROI and tee up the next wave

Publish a value report: hours returned, days to close reduced, backlog shrinkage, cash acceleration, error rates, and audit readiness. Lock in runbooks, resilience (failover, rollback), and training. Queue the next 2–3 use cases using the same playbook. For a fast-track cadence, see From Idea to Employed AI Worker in 2–4 Weeks and Create AI Workers in Minutes.

Stop pilots, start employment: From generic automation to finance AI Workers

The fastest path to durable ROI is employing AI Workers that own outcomes—under supervision—instead of piloting tools that suggest steps you still perform.

Traditional automation (RPA, macros, spreadsheets) moves data but rarely reasons about it, and “copilots” draft content you still must assemble. Finance AI Workers combine reasoning, tool use, and integration to execute multi‑step workflows—like pulling trial balances, reconciling variances, drafting narratives with references, routing exceptions, and posting approved entries—with permissions and logged evidence. This is not replacement; it’s empowerment. Analysts shift from swivel‑chair tasks to exception judgment, scenario modeling, and business partnering. That’s the abundance mindset—Do More With More.

Research backs the pivot: Deloitte finds many teams are experimenting with AI, but measurable value rises when leaders integrate agentic solutions into finance and tighten governance and scenario planning. PwC details practical Responsible AI actions finance can own today: data integrity, human validation, and third‑party oversight. And Gartner shows finance is closing the AI adoption gap—now the differentiator is moving from “AI used” to “AI employed” with audit‑proof execution and visible KPI impact.

The paradigm shift: stop treating AI as a demo and start managing it as a colleague—one you can onboard, supervise, and scale. That’s how midmarket teams win enterprise‑grade outcomes without enterprise‑grade headcount.

Make this the quarter finance becomes your growth engine

You don’t need a new ERP, a data lake, or a 12‑month program to begin; you need two high‑value use cases, minimal data slices, Responsible AI controls, a four‑person squad, and a platform (or AI Workers) that does the work with human oversight and audit evidence. Start with speed and cash, publish the scoreboard, and scale your playbook across close-to-report, P2P, O2C, FP&A, and tax/treasury. With the right approach, AI in finance isn’t a lab project—it’s how your team returns hours, accelerates cash, and earns a stronger seat at the strategy table.

FAQ

Do we need perfectly clean data to start AI in finance?

No—you need decision‑ready slices for each use case plus documented lineage and validation steps; Gartner recommends a “sufficient versions of truth” approach over waiting for perfect data estates.

How do we measure ROI on our first two use cases?

You measure reclaimed hours, cycle‑time reduction (e.g., days to close), exception auto‑resolution rates, error reduction, and working‑capital impact; publish time‑stamped logs and before/after baselines for credibility.

Will AI Workers pass audit and SOX/ICFR scrutiny?

Yes—when you embed Responsible AI controls: source validation, human review at judgment points, evidence capture, and third‑party oversight as outlined by PwC; map each AI step to existing controls and retain artifacts.

What are the best first finance processes for AI?

Start with close accelerators (recons, flux commentary), AP/AR exception handling, anomaly detection, spend classification, and rolling forecast refreshes—high volume, clear rules, measurable outcomes.

Should we build a platform or “employ” AI Workers?

Blend them: use a governed platform for access, observability, and controls; employ AI Workers for outcome‑oriented, multi‑step execution that your team supervises and measures—see RPA vs. AI Workers and real examples in AI in Finance.
