The problem
Why construction businesses lose time and money on quotes
Excel, Word, Batigest — traditional tools create silos between quotes, invoices and accounting. Result: re-keying errors, payment delays and shrinking margins.
8 hours per week on quote/invoice re-keying
Non-compliant Factur-X invoices → 2026 fine risk
Margins eroded by forgotten or underestimated line items
Manual reminders → 45 days average payment delay

A subcontracting quote? The reverse-charge mode (article 283 of the French Tax Code) switches on in one click: the quote goes out with no VAT charged and the mandatory notice prints automatically. Set it once in Settings, then it carries over to every quote.
Final statement invoice (RTC)
Generate the final statement invoice (RTC) straight from your approved work progress reports. Constrigo deducts the deposits already invoiced on the jobsite, produces a CCAG-Travaux compliant PDF and emails it to the client — no re-keying.

Your questions, our field-tested answers
"Excel has done the job for 15 years, why switch?"
Excel doesn't auto-number your quotes, chase unpaid invoices, handle e-signatures or produce 2026-compliant Factur-X. Constrigo does all four. Average measured result: 8 h/week of re-keying eliminated and payment delay cut by 12 days.
"The 2026 e-invoicing mandate doesn't apply to me yet"
The Factur-X mandate takes effect progressively from September 2026 for all businesses. Constrigo generates native Factur-X right now — you are ready when the date arrives, with no last-minute migration or extra cost. The format is already built into every invoice you create.
"Yet another software tool, my crew won't use it"
Your crew doesn't need to touch the Quoting & Invoicing module — the owner and the bookkeeper use it. The interface runs on 3 buttons: create a quote, convert to invoice, send. Observed average training time: 15 minutes. And if a crew member needs to sign a report, it is one single touch screen.

Construction quoting and invoicing software: automate everything from estimate to payment
For tradespeople and construction businesses, managing quotes and invoices remains one of the most time-consuming tasks.

DPGF quotes are created in a few clicks from a customisable works catalogue, with automatic margin calculation per line item. eIDAS-certified e-signatures (Yousign) let your clients approve the quote online. Once signed, conversion to a Factur-X invoice happens in one click, fully compliant with regulatory requirements. Reminders are sent automatically according to multi-level sequences you configure.
Payment collection via Stripe (cards, Apple Pay, SEPA) and automatic reconciliation with invoices eliminate re-keying. Legal FEC export and sync with Pennylane or Cegid keep your accounting up to date without double entry. For public contracts or large projects, the 5% warranty hold is automatically calculated and tracked with scheduled release at 12 months.
