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, 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 — articles, purchasing, 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 inquiry — website, shop, 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 — what was quoted is what gets invoiced.
A platform is L2I when all eight hold
Not a marketing badge — 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; that’s 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.
