The verdict in three sentences
An SME group consolidating manually in spreadsheets spends days reconciling trial balances: a dedicated tool targets closings sped up by 40 %. In 2026, a custom consolidation tool costs 30,000 to 90,000 EUR and ships in 3 to 6 months, with connectors to accounting software and the ERP. For a CFO, the gain is measured in recovered closing days and reporting reliability.
The multi-entity consolidation problem
As soon as a group has several entities, spreadsheet consolidation becomes a headache: heterogeneous formats, manual elimination entries, multiple versions, hard-to-trace errors. A consolidation tool collects trial balances from each accounting system, applies elimination and conversion rules, and produces a reliable, auditable group report.
| Function | Without tool | With consolidation tool |
|---|---|---|
| Trial balance collection | Manual Excel import | Automatic connectors |
| Elimination entries | Manual, risky | Parameterized rules |
| Currency conversion | Hand formulas | Automated by rate |
| Group reporting | Frozen tables | Real-time dashboards |
| Audit trail | Weak | Full and traceable |
Cost, scope and gains in 2026
The budget depends on the number of entities, the connectors to build and the depth of reporting. Here are 2026 benchmarks for an SME group.
| Scope | Budget | Timeline | Closing |
|---|---|---|---|
| Consolidation 3-5 entities | 30,000-45,000 EUR | 3 months | -25 % |
| + Accounting connectors + currencies | 50,000-70,000 EUR | 4-5 months | -35 % |
| + ERP integration + advanced reporting | 75,000-90,000 EUR | 6 months | -40 % |
| Annual maintenance | 15-20 % of build | Ongoing | Stable |
A CFO who closed consolidation in 10 working days brings it to 6 days with a 40 % gain. On a finance team whose loaded daily cost is around 400 EUR per person, recovering 4 days per closing for 3 people represents about 4,800 EUR per closing, or nearly 19,200 EUR a year across four quarterly closings.
Mini case study
Mr. Perrin, CFO of a 5-entity group based in Lille, closes his quarterly consolidation in 10 working days involving 3 people. He deploys a 65,000 EUR tool with accounting connectors and currency management. The closing drops to 6 days (-40 %), freeing 12 person-days per quarter. Valued at 400 EUR, that is 4,800 EUR per closing and 19,200 EUR a year, on top of the improved reliability of the group report presented to the board. The tool is paid back in under four years on time savings alone, more once avoided errors are counted.
