The only bit you do
How a quote for solar installers gets built.
Say it after the survey: 4kW system, two extra panels, a 5kWh battery, scaffold and bird mesh. It comes back with each part priced on its own line, so the customer can see what the battery adds.
Say it or photo it
Voice note the survey, or photo the roof and the consumer unit. Panels, battery, scaffold, mesh and paperwork come back as separate priced lines.
It measures, you check
Put a tape in shot, tap two points and it measures. Anything you didn't measure is marked for you to check.
Priced from your rates
Priced from your own rates. Solar starts you at £6,800 for a supplied and fitted 4kW system, £3,600 for a 5kWh battery, £850 for scaffold and a £300 day rate, and you change every figure to yours.

The materials come with it
The panels, inverter, mounting kit, cable and isolators sit against the system line, the battery and its cabling against the battery. One list to order from your wholesaler.
You can put a names only list on the customer's copy so they can see what you are supplying, with your buying and your markup kept to yourself.
After you tap Send
Most apps stop at the quote.
Yours keeps going.
A quote is the easy half. The half that eats your evenings is the deposit, the diary, the invoice and the chasing. That is the half InstaQuote does for you.
The deposit
You set the deposit on the quote. The customer pays it by card from the link on their phone, with nothing to install, and it lands in your account through Stripe.
The booking
The deposit books the job. They pick a free slot themselves, they get the confirmation and the reminder, and they can move it themselves from the same link.
The calendar
Your week fills in as the deposits land, and it syncs to Google so the diary on your phone matches the one in the van.
The materials
The take off from the quote is ready to go to your merchants for a price, with your markup on it and kept on your side of the paperwork.
The invoice
Mark the job done and the invoice is drafted for you, priced off the quote with the extras you added on site. One tap and it's gone.
The chasing
If it goes past its date, polite nudges go out in your name until it is paid. Three at most, then it stops and tells you. You are not the bad guy and you are not on the phone.
VAT and CIS
Fitting energy saving materials in a home is zero rated for VAT until 31 March 2027, so you set the VAT on that quote to 0% and keep 20% for everything else. Work for a builder or a contractor and the CIS deduction and the VAT reverse charge are worked out for you. You set it per customer, not per quote.
The books
On the Accounts plan (£89/mo) it keeps the books behind all of it: expenses, what each job actually made, and your VAT return figures ready for you or your accountant to file with HMRC.
Start free, no card

3 answers · No small print
The money questions (the trial, cancelling, your data) are answered on the homepage FAQ, and the how-to guides are in Answers.
Can I take a deposit before I order the panels?
Yes. You set the deposit on the quote, the customer pays it by card from the link, and the install books itself into your calendar the moment it lands.
Does it do the MCS certificate or the DNO application?
No. Those go through your MCS body and the network operator. There is a line to charge for the paperwork, and InstaQuote quotes, books, invoices and chases the job itself.
Can the customer see the price with and without the battery?
The battery is its own line, so it is plain what it adds. If you want the two options side by side, send them as two quotes, one with the battery and one without.
