Can the client sign the work order on site?

Yes. The plumber fills in the report from their phone and has the client sign at the end of the job. The signed order goes back to the office and becomes the basis for the invoice, with no re-keying.

Does the tool track my team's RGE qualifications?

Yes. You record each employee's RGE, Qualibat and other certifications along with their validity dates. Constrigo warns you before they expire, so you're never caught off-qualification on a job.

Is Constrigo a good fit for a plumber working solo?

Yes. Constrigo works just as well for a solo plumber as for a team of several employees: you switch on the modules you need and add accounts as the business grows.

Can I turn a plumbing quote into an invoice without re-entering everything?

Yes. A quote signed by the client converts into an invoice, carrying over its lines, quantities and each line's VAT rate. On a job that runs over time, you can also bill the progress through situations rather than all at once.

How do I know if my plumbing jobs are profitable?

Constrigo compares a job's invoiced amount with its costs — hours spent, parts, travel — and works out the margin. You spot the flat-rate call-outs that don't cover the real time and adjust your prices before it shows up in your cash flow.

What is the RGE Qualibat qualification, and does Constrigo track it?

RGE (the French “environmental guarantor” label) is the badge that unlocks access to energy-renovation subsidies; Qualibat is one of the bodies that issue and audit this qualification. Let an RGE lapse and your client loses the right to the subsidies on the job. Constrigo does not award the label — that stays with Qualibat and its audit. What it does: record your qualification with its validity date and alert you before it expires, so you start the renewal before you lose the subsidy benefit.

Q: Does Constrigo handle boiler maintenance contracts?

Yes. You create the contract once and Constrigo schedules the recurring visits at the frequency you set. Each due date creates its own intervention, assigned to the right technician, with no need to reschedule it by hand every year.

Repair quotes, maintenance contracts, signed work orders and up-to-date RGE qualifications: Constrigo brings plumbing and heating together, from the job site to the office, with no double entry.

Why do plumbers spend their evenings on paperwork?

Between emergency call-outs, yearly maintenance visits to reschedule and certifications that expire without warning, everything ends up on sticky notes and two spreadsheets. A yearly visit gets skipped, a work order is never signed, an RGE certificate lapses the day before a job. Constrigo brings maintenance contracts, interventions and qualifications together in one place. The field tech logs the job on site, you approve the report, and the office pulls up the client's history in one click.

What Constrigo does for this trade

Preventive maintenance

Set up your maintenance visits once and Constrigo reschedules them on its own. Each maintenance contract generates its recurring interventions — boiler service, annual inspection, a property manager's portfolio — at the frequency you choose. You can see ahead of time who goes where, and no visit under contract slips through the cracks.

Work orders

Every call-out becomes a digital work order. The plumber enters the work done, observations and a diagnosis from their phone; the client signs on the spot. The report reaches the office right away, ready to turn into an invoice, and stays attached to the job's history.

RGE Qualibat

Keep your RGE and Qualibat qualifications valid without thinking about it. Constrigo records each team member's certifications and their expiry dates, then warns you before a qualification runs out. You walk into a tender or a subsidized job with up-to-date certificates.

Quotes & invoices

An emergency call-out is two lines; a boiler installation is priced in detail. Constrigo does both: you build the quote line by line — labour, parts, call-out — with the right VAT rate on each line, and the client signs it online. Once the job's done, the quote becomes an invoice with no re-keying.

Progress billing & deposits

On a bathroom refit or a plumbing package in a new build, you don't bill everything at the end. Constrigo handles progress billing: you invoice the work done package by package, take a deposit up front and keep track of what's still to collect. Your cash flow no longer hangs on a single end-of-job invoice.

Team scheduling

An emergency call-out lands in the middle of a maintenance round. The schedule shows who's where, who's free and which job can move. You drop the emergency into the right slot, the tech sees it straight away on their phone, and Constrigo flags any overlap before it turns into a client waiting at a locked door.

Job profitability

Not every job pays the same. Constrigo sets what you invoiced against what the job cost — hours, parts, travel — and works out the real margin. You can see whether your flat-rate call-outs hold up, whether a boiler install went over, and set your prices on figures rather than gut feel.
