Three rates coexist in construction. The 10% rate covers improvement, transformation or maintenance work on a home completed more than two years ago. The reduced 5.5% rate applies to energy-efficiency improvement work (insulation, high-performance heating, etc.) and to services inseparably linked to it. The standard 20% rate applies to new builds, commercial premises and the supply of certain equipment. For the reduced rates, the client must give you a certificate. We help you apply the right rate on every quote and invoice.

When you act as a subcontractor on construction work carried out for a main contractor who is themselves VAT-registered, you invoice excluding VAT: it is the main contractor who declares and pays the VAT. Your invoice must then carry the statement “Autoliquidation” (reverse charge) and show no VAT. The main contractor, in turn, includes that VAT in their own return. A mistake in the statement or its application exposes both parties to an adjustment. We check your subcontracting invoices so the mechanism is applied correctly on both sides.

Yes. Any professional carrying out construction or renovation work that engages their ten-year liability must take out décennale insurance before the job starts. For ten years, it covers damage that compromises the soundness of the structure or makes it unfit for use. The certificate must appear on your quotes and invoices. Beyond the legal requirement, it’s essential protection for your business. We build the tracking of your premiums into your accounts and make sure the mandatory statements appear on your documents.

The key is job costing: each site is assigned its own revenue (billed progress) and its own costs (materials, labour, subcontracting, equipment hire, travel). By comparing actuals to the original quote, you spot overruns, mis-estimated items and jobs that erode your margin. This tracking lets you refine your cost prices and price future quotes with confidence. We set up this per-site analysis and give it back to you in a simple, readable form.

Retention lets the client hold back a fraction of the work amount, usually 5%, for one year to cover any defects. In accounting terms, this sum is owed but collected later: it must be recorded correctly so it doesn’t distort your cash flow or your result. When the guarantee period ends, you request its release. You can also replace it with a bank guarantee to collect immediately. We track your retentions, alert you to releases to claim, and factor them into your cash-flow plan.

Construction has its own payroll regime. Your employees’ paid leave is managed by a regional CIBTP fund (paid leave and bad-weather scheme): you contribute to it, and the fund pays out leave as well as bad-weather stoppages. On top of that come sector-specific rules (long-distance travel, meal allowances, travel allowances, Building or Public Works collective agreements). We produce construction-compliant payslips, handle the CIBTP declarations and social contributions, for accurate and secure payroll.
