The verdict in three sentences
Unifying 6 tools into a data warehouse costs in 2026 either 300 to 1,800 EUR/month in a managed setup (ELT + warehouse), or 12,000 to 30,000 EUR excl. VAT for a custom build plus 200-500 EUR excl. VAT/month. Managed is fast and starts low but climbs with volume; custom controls TCO at scale and your specific transformations. Either way, the real win is reliable reporting from 3 days to 15 minutes and a single source of truth.
Data pipeline costs in 2026
A modern pipeline relies on managed ELT (extract-load-transform) to ingest sources, a warehouse to store, and dbt to model. Each brick has its cost.
| Brick | 2026 solution | Cost |
|---|---|---|
| Managed ELT | Fivetran / Airbyte | 200 - 1,200 EUR/month |
| Warehouse | BigQuery / managed Postgres | 100 - 600 EUR/month |
| Connector per source | Build or config | 1,500 - 4,000 EUR excl. VAT |
| dbt transformations | Reporting modeling | 3,000 - 8,000 EUR excl. VAT |
| Full custom pipeline | Ingestion + warehouse + dbt | 12,000 - 30,000 EUR excl. VAT |
| Custom run | Infra + supervision | 200 - 500 EUR excl. VAT/month |
Managed vs custom: 3-year TCO
Managed bills by usage (rows synced): painless at low volume, costly at scale. Custom amortizes a fixed build and stabilizes the run cost.
| Item | Managed (ELT + warehouse) | Custom |
|---|---|---|
| Setup | ~2,000-6,000 EUR excl. VAT | 12,000 - 30,000 EUR excl. VAT |
| Monthly cost (mid volume) | 300 - 1,800 EUR/month | 200 - 500 EUR excl. VAT/month |
| 3-year TCO (mid volume) | ~13,000-70,000 EUR | ~19,000-48,000 EUR |
| Transformation control | Good | Full |
| Marginal cost at volume | Rising | Stable |
| Time-to-value | 2-4 wks | 6-12 wks |
At low volume or to validate fast, managed wins. As soon as synced rows explode (e-commerce, high-volume ads), custom regains the edge over 24-36 months.

Mini case study
Sarah, IT director of a mid-cap in London, consolidates 6 tools by hand: CRM, ERP, support, 2 ad platforms and a finance tool. Two analysts produce monthly reporting in 3 days (~48 cumulative hours, ~2,400 EUR/month loaded), with figures diverging across departments. She picks a custom pipeline at 22,000 EUR excl. VAT + 350 EUR excl. VAT/month. Result: reporting refreshed in 15 minutes, a single source of truth, ~40 h/month freed (~24,000 EUR/year). Payback in ~11 months, with faster decisions on top.
FAQ
Managed or custom to start? Managed to validate in 2-4 weeks. Switch to custom when the ELT bill durably exceeds 800-1,000 EUR/month.
Cloud warehouse or Postgres? BigQuery/Snowflake for large analytical volumes; managed Postgres is enough for a mid-cap with moderate volumes and often costs less.
How many sources at first? 4 to 6 priority sources (CRM, ERP, finance, ads) cover 80% of the reporting need. Add the rest in iterations.
What does dbt actually bring? It turns raw data into reliable, documented models, version-controlled like code, ending the diverging figures between departments.
What is the real ROI? Fewer consolidation hours (30-50 h/month) and above all faster decisions on reliable data, hard to quantify but often the biggest gain.
