What is a purchase trigger?
A purchase trigger is the concrete event that moves a company or a person from not buying to actively looking for a solution: a breakdown, the end of a contract, a new hire, growth that saturates a tool, a regulatory obligation. It differs from the buyer profile, which describes a stable identity. The profile says who you are talking to; the trigger says when that person becomes reachable, which governs the spending schedule.
The forms it takes
An operations director does not switch suppliers because they are forty-two and like cycling. They switch because a contract is coming up for renewal, because a machine failed, or because someone resigned. The most common triggers look alike from one company to the next:
- a breakdown or failure that interrupts operations;
- a contract or subscription coming up for renewal;
- a new hire, a departure or the arrival of a new manager;
- growth that saturates a tool, a space or a team;
- a regulatory obligation or an inspection.
What they share: it is the buyer's own need that brings them into the market, never an advertising message. The Ehrenberg-Bass Institute puts it plainly in its work on business buyers.
How to find it in your sales
Take your last ten closed sales and ask a single question for each: what had happened at that customer in the three months before the purchase. You will rarely get more than five or six distinct events, and they repeat. The exercise costs one hour of a meeting with your salespeople, and the list fits on one page.
Your salespeople and your customer service already hold this information, because they hear it on the phone. No one asks them for it. A company that documents ten real sales gets better targeting than a company that orders a three-day persona workshop.
What it changes in your marketing
Each trigger becomes a content angle, a keyword group and a follow-up moment. The page that answers "what to do when the maintenance contract comes up for renewal" speaks to the buyer on the day they become reachable; the page that describes a typical profile speaks to no one in particular.
The trigger also governs the calendar. Since no message brings a buyer into the market, the work consists of being findable on the day the event happens (in search, in AI answers) and of being already known beforehand, so as to be on the short list the buyer draws up that day. It is the only one of the two pieces of information, profile or trigger, that governs a spending schedule.
Suppose a fictional company that installs industrial ventilation systems. Reviewing its last ten sales, it finds four triggers: an inspection that flagged a deficiency, the expansion of a workshop, the arrival of a new plant manager, and a breakdown in the middle of the production season. No customer said they had seen an ad. Those four events become four pages on the site, four keyword groups and one follow-up rule: call a former prospect back as soon as they announce an expansion or a change of management.
We prefer a list of triggers to a persona document. It fits on one page, is built in one hour with your salespeople, and it changes decisions: the topics of the pages, the keywords targeted, the moments to follow up. A persona describes a stable identity, yet what triggers a purchase is not stable. The persona keeps value as a shared vocabulary in the team and as a writing safeguard, not as a decision instrument.
We read the trigger through the work of the Ehrenberg-Bass Institute: it is not marketing that brings a buyer into the market, it is their own need. Our work therefore consists of making you findable on the day the event happens, and of making you known beforehand, among the buyers who have no active need today.
Not to be confused with
- Buyer persona
- A persona describes a stable identity: role, habits, preferences. The trigger describes the event that moves that person to buy. The first says who you are talking to, the second says when.
- Search intent
- Search intent is what a person wants to get when they type a query. The trigger is the event that caused that search. It comes before, and it explains the vocabulary used.
- Out-of-market buyer
- An out-of-market buyer fits your target audience but has no active need. The trigger is precisely what moves them out of that state.

Frequently asked questions
How do I find my customers' purchase triggers?
Take your last ten closed sales and ask your salespeople what had happened at each customer in the three months before the purchase. You will get five or six events that repeat. The exercise takes an hour and is a better use of time than a persona workshop.
Can advertising cause a purchase trigger?
No, according to the work of the Ehrenberg-Bass Institute: a buyer enters the market through their own need, not because of a message. Advertising and the brand serve another purpose: being already known on the day the event happens, so as to be on the buyer's short list.
What is the difference from a buyer persona?
A persona describes a stable identity; a trigger describes an event. The persona says who you are talking to; the trigger says when that person becomes reachable, and it is the only one of the two that governs a spending schedule. Both can coexist, but only the second changes a budget decision.
