A WattFoundry customer proposal: the energy plan for a commercial warehouse, with system size, year-one savings, 25-year value, and payback

The same proposal on a phone, with Accept Proposal at the top

The math

Hours per proposal, gone to copy-paste.

Reading bills, matching rate schedules, sizing the array, modeling savings, stacking incentives, laying out a PDF. For a shop sending ten commercial proposals a month, that is a week of rep time. WattFoundry does the busywork; your rep checks it and sends it.

Rep time per commercial proposal

Hours → minutes

Bills in, customer link out. The build runs in the background while your rep keeps selling.

Back per rep, per month

~40hrs

Rough math: ten proposals a month at about four hours saved each.

What the customer gets

1link

A branded proposal they read on their phone and accept in one tap. No PDF email chains.

How it works

Four steps in the forge.

Smelt the bills. Cast the proposal. Hammer it into your shop's shape. Quench and deliver. Every step your team used to run by hand is now automated or a single click.

Smelt · intake

Drop in utility bills in whatever form the customer sent: scanned PDFs, phone photos, interval CSVs. AI pulls out a year of usage, the utility, and the rate schedule.

Cast · build

Design on satellite imagery, or let WattFoundry size it for you. The platform builds the proposal: production, savings, incentives, financing, branded layout.

Hammer · sharpen

Edit any line item, adjust pricing, add exclusions, swap branding. Revisions are versioned, so you can always see what the customer saw.

Quench · deliver

One branded link goes to your customer. They review it on their phone and tap Accept. You get notified the moment they open or respond.

Start with what you have

A number today. A full proposal when the data lands.

You rarely get every bill on the first call. WattFoundry looks at the data you have and gives you the best proposal it supports. You never pick the level; it's worked out from the data.

Level 1

Instant Estimate

A ballpark system size and savings range to keep the conversation moving on the first call.

Needs: address + a usage number

Level 2

Preliminary Proposal

A real, branded proposal with design, savings, incentives, and financing, clearly marked preliminary.

Needs: 12 months of usage + the rate

Level 3

Full Proposal

Modeled against the customer's actual rate structure: time-of-use, demand charges, and net billing where they apply.

Needs: whatever the rate requires (monthly TOU splits, demand, or interval data)

Missing data moves a proposal down a level. It never blocks the submission. When the customer sends the rest, resubmit and the proposal moves up.

The build

From bills to a proposal link. Minutes, not hours.

A typical commercial build, start to finish. Timings are rep time on a straightforward single-site job.

0:00

Drop the bills.

Enter the address and drop in the bills. WattFoundry identifies the utility, matches the rate schedule, and pulls out a year of usage.

Bill parsing Rate auto-detect Any format

0:45

Bills read. Rate matched. Rep confirms.

Twelve months of kWh and dollars per meter, rolled up. The rep takes a quick look and clicks Continue.

For homeowners and business owners

Got a solar proposal from WattFoundry?

If you searched for us after getting a proposal link, here's the short version: WattFoundry is software. A solar company used it to build your proposal. We don't sell, install, or finance solar systems ourselves.

Who made my proposal?

The solar company or sales rep named on the proposal. They chose the equipment, set the price, and are the ones you'd be working with.

Who do I ask about it?

Your installer or rep. Questions about pricing, equipment, timelines, or the installation itself go to them. We can't change a proposal.

What happens if I tap Accept?

Your installer is told you want to move forward, and they follow up with next steps and the contract. Nothing is charged through WattFoundry.

My link stopped working.

Proposals can expire or be replaced by a newer version. Ask your installer for a fresh link. Still stuck? Email keaton@wattfoundry.ai.

Frequently asked

The short version.

What is WattFoundry?

Proposal software for solar installers and sales reps. It reads utility bills, designs the system, models savings, incentives, and financing, and publishes a branded proposal the customer can accept online. WattFoundry is a Garner Solutions LLC product.

Why not just use the proposal tool we already have?

Most proposal tools are calculators. You still spend hours per deal typing in bills, looking up rate schedules, configuring arrays, and assembling a PDF. WattFoundry automates that end to end, so your rep checks and sends instead of building.

Do you support my utility and state?

Most major US investor-owned utilities are read automatically. Any rate anywhere in the US can be entered by hand in a couple of minutes. If yours isn't covered, email us; we add utilities regularly.

Is there a free trial?

Yes. Every account starts with 3 free proposals, with no time limit and no credit card. Upgrade when you need more.

How do I get started?

Sign up at app.wattfoundry.ai. Every account starts with 3 free proposals, no time limit and no card. Want a walkthrough first? Book a demo and we'll show you WattFoundry on your own projects.

Who owns the proposals I build?

You do. Proposals publish on a private WattFoundry link carrying your branding. Links stay live while your account is active.

Can I change or cancel my plan?

Yes. Upgrade, downgrade, or cancel anytime. Canceling stops renewal, and your account stays active through the end of the paid period.

I received a proposal. Is WattFoundry my solar company?

No. Your solar company built the proposal using WattFoundry. For anything about the price, equipment, or installation, contact the company named on your proposal. More for customers.
