Creating a contract
From Dashboard → + New contract.
Required fields
- Name — free-form identifier (max. 200 characters)
- Formula — indexation type (see below)
- Reference index — INSEE series code (e.g. BT01, SYNTEC, ILC)
- Initial price P₀ — pre-tax amount at the signing date
- Index value I₀ — index value at the reference month
Optional fields
- Reference period (YYYY-MM) — if absent, the calculation uses I₀ as-is
- Client name — internal memo
- Frequency — 3, 6, 12 or 24 months (default: 12 months)
- α / β — custom coefficients (CCAG and Free formula only)
Indexation formulas
CCAG Works (BT/TP)
Standard formula for public works contracts (French public procurement code).
P = P₀ × (α + β × I / I₀)Default: α = 0.15 · β = 0.85. These coefficients are stated in the contract's revision clause.
Compatible indices: all BT series (BT01–BT50) and TP.
Syntec / ICS
Formula for IT service contracts (Syntec / OPIIEC collective agreement).
H = H₀ × (0.2 + 0.8 × S / S₀)- Fixed part: 20%
- Variable part: 80% (SYNTEC or ICS index)
Compatible indices: SYNTEC, ICS.
ILC — Commercial lease
Commercial Rent Index. Simple formula:
L = L₀ × (I / I₀)⚠️ Legal note: French law caps ILC variation at the previous year's variation. IndexFacile displays a warning when this cap is reached. Verify the amount with your notary or legal advisor before notifying your tenant.
ILAT — Tertiary activity lease
Same formula as ILC, applicable to tertiary activity leases.
IRL — Residential lease
Reference Rent Index, published quarterly by INSEE.
L = L₀ × (I / I₀)Free formula
For any other contract. You freely define the coefficients and can reference up to 2 indices.
P = P₀ × (α + β × I₁/I₁₀ + γ × I₂/I₂₀)Constraint: α + β (+ γ) = 1.
Revision frequency
The frequency determines how often the cron job calculates revisions for this contract.
| Value | Use |
|---|---|
| 3 months | Quarterly revision contracts |
| 6 months | Semi-annual revision |
| 12 months (default) | Annual revision (most common) |
| 24 months | Biennial revision |
The dashboard displays a Revision due badge when a revision is overdue relative to the defined frequency.
Archiving a contract
An archived contract is no longer counted towards your active contract quota and no longer triggers automatic calculations. The revision history is preserved.
From the contract page: Archive button. To reactivate: Unarchive.
CSV import (Cabinet)
The Cabinet plan allows bulk contract import via CSV.
