How to generate an optimal quote with Argile

Clarifying the goal of an optimal quote in energy retrofit (what changes in 2026 on the ground)

Defining "optimal" without missing the target

An "optimal" quote is not the cheapest one. It is a quote that is compliant with aid requirements, profitable for your business, readable for the client, and that raises your signature rate. On the ground in 2026, scrutiny of supporting documents and mentions has increased, with applications that can get blocked if the quote or invoice does not clearly link the works, the address, the site visit, the stated performance and the RGE status.

Documents and data needed before costing

• Address, year of construction, heated surface, photos, site access, electrical and drainage constraints.
• DPE (France's energy performance certificate) and, depending on the process, an energy audit and a class-improvement scenario.
• Choice of equipment, output, efficiency, labels, plus installation and control details.
• RGE, CEE operation references, and client documents for the aid (identity, tax notice, proof of ownership, bank details).

Anticipating client expectations without overwhelming them

The client wants to understand, not study a manual. Give them 3 simple pieces of evidence, measurements, site-visit photos, and a before/after comparison on consumption and comfort. This is where a quote compliant with aid requirements makes full sense. You structure the costing, you display the aid, and you keep a clear, educational thread, like a light guiding the project.

Preparing your technical site visit to collect the right information on the first visit

A well-framed technical visit is the light switched on over the whole job site. Start by surveying the key points of the building. Measure the surfaces per wall and note the type of substrate, the thickness and type of insulation, and the continuity of insulation at the junctions. Look for signs of thermal bridges and dampness. Also check the ventilation. Type of mechanical ventilation, condition of the vents, duct routing, access to the unit. This information determines comfort and prevents defects.

• Surfaces useful for costing. Walls, loft, floors, joinery.
• Ventilation. Location of air inlets, outlets, ducting, maintenance constraints.

Then quickly identify the constraints at the address. Truck access, parking, passage width, façade height, presence of a cellar or crawl space. On the roof side, note the pitch, condition, key points and tricky areas. For shared walls, clarify boundaries and overhangs. Check the networks. Available electricity, drains, possible location of units and connections.

Finally, secure the quote with usable photos and measurements. Take wide shots and close-ups of penetrations, hatches, panels, loft, sills, and reservations. Note what is missing on site. This is the basis for "generating an optimal quote with Argile" without costly return visits or surprises during installation.

Creating a quick energy study with Argile to frame the project in under 5 minutes

Assessing the initial state and the energy performance of the dwelling

With Argile, you start from a clear picture of the existing situation, without losing a whole morning. In a few entries, you estimate the initial energy performance, identify the weak points of the envelope (roof, walls, floors, joinery) and the air- and moisture-related risks. This baseline helps you frame client expectations, winter comfort, summer comfort, bills, and avoid "good ideas" that create problems.

Comparing several work scenarios, single measure vs. whole-house renovation

You test several paths. A single measure can deliver a targeted gain, but a whole-house approach brings the work packages into coherence. Argile lets you present 2 to 3 readable scenarios, with impacts on consumption, comfort and the order of works. This is a concrete lever for answering the question How to generate an optimal quote with Argile without overselling.

Prioritising the works, comfort, savings and technical coherence

• Insulation and airtightness first, where the losses are greatest.
• Ventilation suited to secure air quality after insulation.
• Heating sized afterwards, to avoid oversizing.

Checking feasibility and securing your costing before writing a single line

Before talking euros, secure the ground. With Argile, you can automatically spot constraints via Open Data, then confirm them on the visit. Access, protected zone, roof type, altitude, acoustic constraints for the outdoor unit, everything that can derail a heat pump installation or insulation job. On site, you validate the useful measurements, duct routing, condition of the networks, and above all the points that don't show up on a plan.

This step avoids the classic pitfalls. A heat pump output that is poorly calibrated leads to electric backup or short cycling. Undersized ventilation lets moisture settle in after insulation. Incomplete insulation creates thermal bridges and after-sales callbacks. For "How to generate an optimal quote with Argile", the idea is simple. You start from clear, verifiable assumptions.

• Included: protection, drilling, drainage, commissioning, ventilation balancing, adjustments.
• Not included: electrical compliance work, decorative touch-ups, asbestos removal, structural works.
• Variants: heat pump alone or heat pump + hot water tank, level of insulation, single-flow or humidity-controlled ventilation.

Generating a clear and complete quote with Argile, ready to be signed

From pre-costing to detailed quote

How to generate an optimal quote with Argile. You start from a pre-costing, then turn it into a quote structured by work package. Insulation, heating, ventilation. Each package breaks down into line items with measurable quantities. Surface, linear metres, number of units. The result, the client understands what they are paying for, and you keep control of what you install. Add site constraints and induced supplies to avoid "oversights" that end up as amendments.

A readable quote, even for a non-specialist

Argile helps you present a simple phasing. What is done first, what depends on another item, and what can wait. Offer 1 or 2 options, clearly separated, with a price and timeline impact. On the performance side, indicate the expected benchmarks. Target thermal resistance for the insulation, COP or SCOP for a heat pump. Without overloading, just enough to reassure.

MaPrimeRénov' and CEE aid, without promises

Include an estimate of the MaPrimeRénov' and CEE aid, specifying that it is subject to eligibility, application before works and compliant documents. Display the indicative remaining cost, and keep a clear line between the price of the works and the aid. You are selling confidence, not a bet.

Building trust and increasing your signature rate through a structured presentation

From the "why" to the "how", with no grey areas

A presentation that gets signed starts by explaining the why of the works. You start from visible problems (cold, dampness, bills) and link each measure to a concrete benefit. Immediate comfort, lasting savings, a healthier home, property value. Then you unfold a logical order, first the envelope and airtightness, then ventilation, finally heating. This thread avoids inconsistencies and reassures. You also gain credibility by anticipating objections. Budget, you show the remaining cost after aid and the options by package. Timeline, you announce a realistic schedule with milestones. Disruption, you describe the site organisation and protection of rooms. Guarantees, you recall the insurance cover and traceability of materials. Finally, you offer a simple journey. Steps, visit, measurements, quote, aid application, works, handover. Conditions and documents to provide, DPE or audit if needed, supporting documents and agreements. This is exactly the spirit of software to save time and sign more quotes.

• Clear steps, a single point of contact, decisions at every milestone.
• Readable schedule, estimated dates and dependencies (aid, supply).
• Documents listed from the start to avoid back-and-forth.

Saving time on admin in 2026 and avoiding back-and-forth

In 2026, aid and CEE applications do not forgive contradictory information. To avoid redoing quotes, centralise every supporting document in one place and track every change. Even a simple correction, like a surface area, a product reference or a date, must leave a dated version. You also secure your exchanges with the client and your partners. Next, prepare a clean aid application right from the costing stage. Ensure consistency between identity, dwelling address, occupancy status, RGE company, nature of the works, aid amounts and cumulative totals. Add the expected documents from the start, such as the tax notice, the detailed quote, and the invoice at payment time. Finally, put in place a company standard. Use quote templates, checklists per work type and a quality check before sending. This is exactly the spirit of generating an optimal quote with Argile. One well-built file, and you keep control of the job site, not the paperwork.

• A single reference point for documents and versions, accessible to the team.
• A checklist before submission and before requesting payment.
• A final check of the mandatory mentions and amounts.
