How we remove the friction between Finance and IT, preferably before it arises. One lead for both, from your first question to a system your team genuinely embraces.

How the tiers fit together

One Sprint, four ways to run it.

Everything starts with the Transformation Sprint: one measurable leap in 90 days. Tier I–III bring the same approach in lighter form when your team wants to carry more of the work itself. The overview shows who does what in each phase and what keeps the gains after hand-off.

Overview ‘One Sprint, four ways to run it’. Left: a decision tree with four questions leading to Tier IV Transformation Sprint (HAAI does it, 90 days), Tier III Finance Systems Lead (HAAI leads, team and partner build), Tier II Advisor (your team builds, HAAI steers monthly) or Tier I Sparring (you do it, HAAI spars weekly). Centre: the five phases of the Sprint – Diagnosis, Blueprint, Implementation, Knowledge transfer, Hand-off – with, per tier, who does the work: HAAI, together or your team, separated by quality gates signed off by finance and IT. Right: what keeps the gains after hand-off: Advisor as the default route (monthly review and a quarterly roadmap), Finance Systems Lead when the Diagnosis surfaced an ERP or automation project, Sparring as a weekly safety net. Next measurable leap: a new Sprint with a new baseline.

Tier I

Sparring

€ 1,500/ month

One lead for your finance and IT questions, before they become problems.

The same five phases as the Sprint — you do it, HAAI spars weekly.

A permanent sparring partner at board level who covers both finance and IT, without you hiring a CFO or IT manager. Ideal when you know things can be better but not yet where to start, and before you commit to a system, process or partner.

  • Weekly contact at a fixed time
  • Unlimited asynchronous support in between: a quick check before you decide, sign or escalate
  • Independent second opinion on plans, quotes and partner proposals
  • A monthly 2-pager naming the frictions we see, with concrete recommendations
Tier II

Advisor

€ 4,500/ month

Reliable numbers from systems your team actually uses.

The same five phases as the Sprint — your team builds, HAAI steers monthly.

Monthly steering by one lead who looks at your finance processes and your systems together. Whether you run a new ERP, an older system or mostly spreadsheets, we find where manual work and workarounds slow you down, and remove them step by step.

  • Monthly management review that turns system output into decisions
  • Process walkthroughs to find manual work, spreadsheet workarounds and processes that run outside the system
  • A prioritised automation backlog, agreed by finance and IT together
  • Ongoing maintenance of your management reporting, including a first layer of AI (e.g. anomaly detection)
  • A quarterly roadmap: what we tackle next quarter, in which order and why
Tier III

Finance Systems Lead

€ 9,500/ month

Your finance systems lead on the client side, from requirements to a go-live your team embraces.

The same five phases as the Sprint — HAAI leads, your team and the partner build.

One lead for both the finance and the systems side of your ERP or automation project. We represent you towards the implementation partner, design the finance processes and controls, and keep your financial management running while the project runs, including fractional CFO support where needed.

  • Everything in Advisor, plus:
  • Client-side project lead: planning, scope, budget and steering committee reporting
  • Requirements and process design, translated between finance and the implementation partner
  • Controls built into the design: authorisations, segregation of duties and audit trail
  • Data migration, testing and go-live readiness with finance sign-off, plus key users, training and adoption as a go-live criterion
  • Fractional CFO support: board and investor preparation, forecasting and financial modelling

Tier IV

Transformation Sprint

Success fee

One measurable leap in 90 days. No savings, no fee.

Everything starts here — HAAI does the work, in 90 days.

Want to improve but not sure where to start? The Diagnosis phase finds where the biggest gain lies, whether in finance processes, reporting, systems or ways of working, and one lead implements it with you within 90 days. Fixed quality gates, a team that can carry on without us, and a fee based entirely on the savings delivered.

  • Five phases: Diagnosis → Blueprint → Implementation → Knowledge transfer → Hand-off
  • Fixed quality gates, signed off by finance and IT together
  • Pragmatic in-house tooling, or the right external partner where heavy customisation is needed
  • Adoption is an exit criterion: we only hand off once your team works the new way
  • No savings, no fee: the fee is a share of the savings delivered, calculated at hand-off against the baseline set in the Diagnosis phase
  • After hand-off: Advisor keeps the gains (default route), Finance Systems Lead if the Diagnosis surfaced an ERP or automation project, Sparring as a weekly safety net
  • Next measurable leap? A new Sprint, with a new baseline
For audit & accounting firms

Audit Lab

Success fee

It is delivered by one lead who combines audit and IT expertise (CISA).

  • Standardised data extraction from common ERP and accounting systems
  • AI models for materiality, risk detection and unusual transactions
  • Integration into your existing audit methodology and files
