What is Lead-to-Invoice?
You came looking for a CRM, or maybe an ERP. Lead-to-Invoice (L2I) is why neither word quite fits an installation business, and what we built instead.
The complete commercial cycle of an installation business: every step between a customer’s first inquiry and the paid invoice, run as one connected flow.
CRM stops at the win. ERP starts at the order. Your business is the whole cycle.
What a CRM covers
Leads, contacts and deals, up to the moment the customer says yes. Then it hands off: the quote is a document, the project is someone else’s spreadsheet, the invoice lives in accounting.
What an ERP covers
Resources such as articles, purchasing and finance, from the order onwards. Sales is an input from somewhere else, and the customer’s journey before the order is invisible.
An installation business doesn’t have a CRM-shaped problem or an ERP-shaped problem. It has a cycle-shaped problem: the seams between tools are where hours, margin and customers leak. L2I closes the seams by running the whole cycle on one platform.
Five stages. Zero seams.
Lead
Every enquiry, whether from the website, the shop or the phone, lands in the same system that will quote it.
Quote
Quotes are built from your live product catalog and real prices, not copied documents.
Win
The customer accepts a branded proposal online, recorded on the same record the lead opened.
Work
The won quote becomes a planned project; the field team sees it live on mobile.
Invoice
Billing is generated from the same record, so what was quoted is what gets invoiced.
A platform is L2I when all eight hold
Not a marketing badge but a checklist you can run against any platform, including ours.
Score your current stack honestly; most installation businesses pass two or three. Currently passes all eight, and that is the standard we built it against.
L2I is bigger than one product
The full definition, the five stages and the eight criteria are maintained as an open, vendor-neutral standard at lead-to-invoice.com, written so you can hold any vendor to it.
