The verdict in three sentences
A mid-market company juggling four tools (spreadsheets, generic CRM, stock management, invoicing) accumulates re-entry, errors and delays. Replacing that stack with a custom business platform at 90,000 EUR excl. tax in 2026 cuts data-entry hours by 35%, errors by 70% and processing times by 50%. The return on investment, computed on time saved and errors avoided, is reached in about 14 months: here is the full business case.
Measured before / after over 12 months
These indicators come from a 120-employee B2B distribution mid-market company, one year after platform deployment.
| Indicator | Before (4 tools) | After (platform) | Change |
|---|---|---|---|
| Data-entry hours/month | 640 h | 416 h | -35% |
| Order error rate | 6.5% | 2.0% | -70% |
| Order processing time | 48 h | 24 h | -50% |
| License costs/year | 28,000 EUR | 6,000 EUR | -79% |
| Monthly close time | 8 days | 3 days | -62% |
| Team satisfaction (internal NPS) | +5 | +42 | +37 pts |
The quantified business case
A defensible business case sets total investment against annualized gains. Here is the structure presented to the executive committee.
| Item | Amount EUR excl. tax (2026) |
|---|---|
| Custom platform development | 72,000 |
| Data migration and integrations | 10,000 |
| Training and change management | 8,000 |
| Total investment | 90,000 |
| Annualized data-entry time gain | 47,000 |
| Annualized license saving | 22,000 |
| Reduced cost of errors | 8,000 |
| Total annual gain | 77,000 |
| Return on investment | ~14 months |
The data-entry time gain values 224 hours saved per month at a loaded cost of 35 EUR/h, i.e. about 47,000 EUR per year. On top of that come the removal of redundant licenses and the lower cost of order errors.
Mini case study
Claire, CFO of an industrial SME in Lyon, must justify a 90,000 EUR excl. tax investment to her leadership. She builds the business case on three levers: 224 data-entry hours saved per month, 22,000 EUR of licenses removed per year, and a 70% drop in order errors that generated credit notes and disputes.
Her calculation: 47,000 EUR of time + 22,000 EUR of licenses + 8,000 EUR of avoided errors = 77,000 EUR annual gain. Against the 90,000 EUR investment, the return is reached in ~14 months, after which the gain becomes recurring. The committee approves the project on this ratio, with quarterly indicator tracking.

FAQ
How do I justify 90,000 EUR to my leadership?
By setting the investment against annualized gains: data-entry time, removed licenses and avoided errors. A 14-month return with quarterly-tracked indicators is a strong committee argument.
Are these gains guaranteed?
These are 2026 orders of magnitude from comparable projects. Results depend on your maturity and change management, but a 30 to 40% drop in data-entry time is a realistic, measurable target.
Why replace 4 tools with a single platform?
Because re-entry between tools is the top source of errors and wasted time. A single platform removes double entry, unifies data and drastically cuts license costs.
How long to deploy a custom platform?
Expect 4 to 8 months depending on scope and integrations. We proceed in functional batches to deliver value early and secure adoption before adding modules.
What happens after the ROI is reached?
The 77,000 EUR gain becomes recurring each year, minus a maintenance cost (typically 12 to 18% of the initial budget per year). The platform keeps evolving with your business.
