A sales funnel is a model of how a large pool of leads narrows into a smaller set of paying customers as people move toward a purchase. Each stage holds fewer prospects than the one before, because some drop off along the way. Unlike a pipeline, which tracks the seller’s actions, the funnel is framed around the buyer’s journey and where people fall out.
How it works
Funnels are usually drawn in stages that get narrower from top to bottom. A common version is awareness, interest, consideration, intent, and purchase. At each step, a share of people leave: they lose interest, pick a competitor, or go quiet. The percentage that moves from one stage to the next is your conversion rate, and the gap between stages shows where you are losing demand.
Why it matters
The funnel gives you a shared language for diagnosing where deals stall. If plenty of people request pricing but few buy, the problem sits low in the funnel, near the offer or the checkout step, not at the top. That points you to a fix (clearer pricing, faster follow up) instead of pouring more traffic into a leak.
In B2B quoting on Shopify
For merchants who sell by quote, the funnel often runs: store visit, quote request, quote sent, quote viewed, quote accepted, and payment. Watching drop off between “sent” and “viewed” or “viewed” and “accepted” tells you whether buyers are ignoring quotes or seeing them and balking at terms. Tools that track opens, clicks, and conversions on a quote let you measure these stages instead of guessing. See related terms in the B2B quoting glossary.
