Single installer
You install solar yourself and sell your own systems. There's nothing to compare, but speed and a clean quote still win the deal.
The hard way
A lead comes in, your team follows up a day later with a rough number and "we'll send a proper quote soon." By then the homeowner has spoken to someone faster.
With InstantInvoice
The SMS books the call, and the configurator sizes the system and prices it right on the first call, so you send a correct, good-looking quote on the spot instead of days later.
- ✓ Booked the call fast with an SMS
- ✓ Sized and priced the system correctly on the first call
- ✓ Sent a professional quote on the spot, not days later
The math: Same commission (~€2,000 on a typical system), but you stop losing deals to whoever quoted faster.
