A growing marketing agency wanted to clarify its operational everyday tasks, systems, and data usage. Tervahauta Consulting conducted a comprehensive current state assessment and developed three alternative operating models, one of which was chosen as the foundation for the company's growth and AI readiness.
The case pages are intended as a portfolio of work samples. They are based on real companies, but for confidentiality reasons, names and other identifiable details have been changed.
Three realistic paths were identified for the operational renewal of the office. They differ in what the company wants to emphasize: the tool experience of the staff, simple architecture, or cutting-edge growth and forecasting capabilities.
Idea: retain the team's favorites (Toggl, Pipedrive, Slack), add a lightweight integration layer and data warehouse.
Idea: one system family (Severa + Netvisor) → one truth of the data, minimal maintenance.
Idea: world-class stack (HubSpot + Productive + Netvisor + Teamtailor + Power BI, a lightweight data lake is a possible addition).
Fits if: the goal is growth, AI forecasts, and transparency across the office.
Pros: best PSA, best CRM, excellent dashboard, strongest AI readiness.
Challenges: highest investment, slightly more complex implementation.
Cost: €18,000–30,000 + €1,380–2,700/month.
Internal work: 70–100 hours.
The winner is Agency OS, as the agency wants to prepare for rapid scaling and take advantage of AI opportunities ahead of others.
People First solves usability but lacks predictability.
Severa-first is cost-effective but limited at the PSA/CRM level.
Agency OS offers the best overall view and the strongest data foundation for management needs.
Annual total costs:
≈ 22,000 – 34,000 €
Annual ROI: x10 – x15
Payback period of 2–6 weeks is based on the immediate elimination of process-related waste in the billing rate, budget leaks in project margins, and corrective work in HR/payroll, allowing the company to gain €15k–€22k per month in new value starting from the first month.
ROI estimates have been calculated conservatively and are based only on waste from process, data, and manual work, not additional sales.
The main benefit of the reform came from the work becoming less reactive and more predictable. As sales, time tracking, projects, and invoicing now go through the same process, everyday friction and corrective work decreased immediately. The financial impact was mainly visible as a reduction in operational waste.
I am currently open to recruitment discussions and looking for a permanent position.
