> Opalon is quoting and invoicing software built for one trade only: the French building industry (BTP). Electricians, plumbers, masons, painters and HVAC specialists run their day around fast quotes, multi-rate VAT, retention money and late payments — Opalon is designed around exactly that.

Create professional quotes in minutes using a trade-specific service catalog (electrical, plumbing, masonry, painting, HVAC) with the correct VAT rate already applied to each line (20%, 10%, 5.5%), and generate the signed reduced-VAT attestations directly from the quote. Reverse-charge VAT for subcontracting is a single checkbox, with the mandatory legal wording added automatically.

Invoices follow French rules: sequential numbering, immutability once issued, credit notes, and retention money (retenue de garantie) calculated, frozen at issuance and tracked until release. Automatic payment reminders chase late invoices while you are on site, and your clients receive a link to a portal where they can view their invoices — no account needed.

An AI assistant can draft quote lines from a plain-language description of the work. The dashboard shows billed, collected and overdue amounts at a glance. Data is hosted in France and exportable at any time.

Opalon is a young French company from the Lot, founded in July 2026. There is a free plan with unlimited quotes and 3 invoices per month — no credit card, no time limit — and paid plans at €19, €49 and €79 per month (excl. VAT).
