    What is a customer prospect, in one sentence?

    A customer prospect is a person at a company that fits your ideal customer profile (ICP) and could buy from you, but has not bought yet. "Prospective customer" and "prospective buyer" mean the same thing. Take a software firm that sells to building contractors: the head of procurement at a 300-person contractor that fits its buyer profile is a prospect, even before she has heard of the firm. The day she replies, she becomes a lead.

    The quickest way to keep the related words apart: a prospect is about fit, a lead is about response, a customer is about a signed deal. Before the prospect sits the suspect, a company nobody has checked yet. After the customer comes the client, a buyer you keep working with.

    The word shifts a little between departments. Some teams use "prospect" for anyone on a target list, checked or not. Adobe's guide to leads vs prospects says some people use lead, prospect and opportunity interchangeably, but they describe different types of prospective customers.

    Inbound-minded guides put the prospect after the lead. Adobe puts it in one line: "A prospect is a qualified lead."

    I use the outbound meaning: someone whose company and title have been checked and who is worth a direct approach by name, before any contact. And I am strict about it. A name only counts as a prospect on my lists once someone has compared the company with the client's existing buyers and found the person who really signs off on that kind of purchase. Until then it is a suspect, however good the logo looks.

    The trouble starts when marketing and sales share one CRM and one monthly report, and each team counts a different group under the same word. The pipeline number then means two things at once.

    Why do vendors disagree on whether the prospect comes before or after the lead?

    Read a few CRM guides and you will find the prospect placed before the lead in some, after it in others. The disagreement comes from which team the writer had in mind.

    Inbound teams meet the lead first. Someone fills in a form, downloads a guide or starts a trial. That person is a lead the moment they act. Sales then checks whether they are worth a real conversation, and the ones who pass get called prospects or sales qualified leads.

    Outbound teams meet the prospect first. You choose a company that fits and a person inside it who decides. That person is a prospect before they have ever heard of you. They become a lead only when they reply.

    My team works mostly through cold email and LinkedIn outreach, so on our side the prospect always comes before the lead. I treat the first reply as the moment a prospect becomes a lead, because a reply is where a conversation starts.

    StepInbound orderOutbound order
    1A person finds you: form, download, sign-upYou pick an account and a person who fit your ICP
    2They are now a leadThey are now a prospect
    3Sales checks whether they qualifyYou run a sequence of touches
    4Those who pass become prospects (or SQLs)Those who reply become leads
    5A deal is opened: opportunityA reply clears qualification and a meeting is booked: opportunity
    6A closed deal: customerA closed deal: customer

    The two CRMs most founders meet first show the same split. HubSpot's default lifecycle stages run Subscriber, Lead, Marketing Qualified Lead, Sales Qualified Lead, Opportunity, Customer, Evangelist and Other (HubSpot lifecycle stages).

    There is no stage called prospect. The closest is the Sales Qualified Lead, which HubSpot defines as a contact or company that sales has vetted as a possible buyer. That is the inbound meaning of prospect, sitting after the lead.

    Microsoft's Dynamics 365 Sales works with lead records and opportunity records. Qualifying a lead confirms it is a genuine sales opportunity, links an account and a contact to it, and creates the opportunity record.

    Microsoft's own example of when to qualify is a prospect who shares their budget and a firm timeline for deciding (Microsoft Learn, Dynamics 365 Sales). In that product, "prospect" is just the person behind the lead record.

    Decision rule: Any order works if it is written down. Pick one, write a one-line entry rule for each stage and map every rule to the stage names your CRM already has. If you run inbound and outbound side by side, keep one order and add a source field, so a lead from a form and a lead from a cold reply never get counted as the same thing.

    Suspect, prospect, lead, opportunity, customer, client: which stage is which?

    Here is the full ladder in the outbound order, with the CRM names next to each rung. Qualification sits between lead and opportunity as a gate, a quick check every lead passes through before a deal opens.

    StageEnters whenWho owns itHubSpot stageDynamics 365Moves up when

    CustomerAt least one closed dealWhoever closed itCustomer (at least one closed deal)Outside the lead processA second purchase or a retainer starts
    ClientAn ongoing relationship with repeat or retained workAn account managerNo separate stageOutside the lead processRenewals and new projects

    A few boundaries cause most of the arguments.

    Suspect vs prospect. The only difference is the fit check, and it is easy to skip. A list bought by industry and headcount is a list of suspects. It becomes a prospect list once somebody has confirmed that each company resembles your buyers and that each name decides something.

    Lead vs opportunity. A reply is a lead. A reply that says "sounds interesting, send me a time" is still a lead until it clears the gate. The four signals in the gate row do that work. Customer qualification covers the method and the questions behind each signal.

    Opportunity vs customer. Booking a meeting and closing a contract are two different jobs, so on my reports a booked meeting stays an opportunity until the paperwork is done. When I review a campaign, I count booked, attended and closed as three separate numbers, because a gap between any two of them points to a different problem.

    Customer vs client. A customer has bought. A client has a relationship that keeps going: a retainer, a renewal, a second project. The practical difference is who owns the record: a customer can stay with whoever closed the deal, while a client needs an owner whose job is keeping the relationship.

    Is the prospect a person or a company?

    Both, and in B2B each needs its own stage. The company is the account, and it either fits your ICP or it does not. The person is the contact, the one you actually write to. It is the same split that separates an ICP, which describes the company, from a buyer persona, which describes the person.

    The account decides whether anyone there is worth contacting. The contact decides whether your message lands at all. A perfect account with the wrong person on the record is still a suspect. Period.

    Getting the person right starts from evidence you already have:

    • My starting point is the client's existing and former customers, and from there I look for similar companies.
    • On every past deal I work out who actually made the buying decision.
    • I search with the titles that niche really uses for that person, such as Head of Procurement or Project Director, instead of a plain "manager".
    • I strip generic titles such as Assistant, Manager and Associate out of the target list entirely.

    A construction company might buy through a head of procurement on one project and a project director on another. A software firm might buy through a VP of IT. A "decision maker" filter in a lead tool does not tell you which of these titles signs off on your kind of purchase.

    Two more rules follow from the split. One account can hold several prospects, and each one needs its own stage and its own message, because a project director and a procurement head care about different things.

    And an account can be a customer while a contact there is still a prospect. If you sold to one division, a second division with its own budget starts again at the prospect stage. Mark the account as a customer and the new contact as a prospect, or your reports will count a cold name as a warm one.

    On my campaigns each account gets one owner, and nobody else on the team contacts that company.

    How many prospects become customers? One labeled outbound funnel

    One LinkedIn account, 30 days, 1,200 people contacted. That was one of our campaigns, and each count below carries its rung from the ladder.

    Count after 30 daysWhat happenedStage name
    1,200Contacted from one LinkedIn accountProspects
    289RepliedLeads
    21Said they were interestedInterested leads
    16Booked a meetingOpportunities (meeting booked)
    12Showed up to the meetingOpportunities (meeting held)
    3ClosedCustomers

    The campaign data has no separate row for the fit check or the qualification gate, so read those rungs as folded into the rows above.

    Mislabel the 289 replies and you fix the wrong thing next month. Call them prospects and the list looks weak. Call them pipeline and you expect dozens of deals, then kill the campaign in month two. I see founders do this all the time.

    A reply count this size is why volume matters. A handful of hand-picked "perfect fit" names cannot show you whether the list is weak, because a buyer who is busy, not ready yet or simply not interested looks exactly like a bad fit. Judging a campaign on a few dozen names is a lottery ticket.

    The steepest percentage drop in the table sits between the 289 replies and the 21 people who said they were interested, about 7%. A reply is only a lead, which is where prospecting ends and lead generation begins. That is why I never report replies as pipeline: I count conversations first, because meetings come out of conversations and customers come out of meetings.

    The filter from suspect to prospect is what keeps the top row honest. When Gartner surveyed 632 B2B buyers in August and September 2024, 73% said they actively avoid suppliers who send irrelevant outreach (Gartner). Writing to unchecked suspects is the quickest way to become one of those suppliers, and to fill your CRM with unqualified leads.

    What should a prospect record contain? A template

    Copy these fields into your CRM or a shared sheet. The sample column describes one invented prospect, so you can see what a filled-in record looks like.

    FieldSample valueWhy it is there
    Account nameA regional main contractor in the North West of EnglandTies every contact to one company
    WebsiteThe company's own domainConfirms the business and gives you the email domain
    IndustryConstruction, commercial buildingsLets you match proof to the niche
    Company sizeAbout 300 staffPart of the fit check
    ICP fit reasonSame size and project type as two current customersForces someone to write down why this record counts as a prospect

    LinkedIn URLProfile linkUsually the first touch
    Data sourceThe tool or list it came from, plus the date pulledYou may have to tell the person where you got it
    Lawful basisUK GDPR legitimate interests, assessment on fileNeeded for UK and EU contacts
    StageProspectOne stage per contact, from the ladder
    Fit scoreHighHow well account and title match
    Engagement scoreLow, no reply yetWhat the person has done so far
    Touches so far2 of 6Shows whether the sequence ran its course
    Last touchDate and channelStops two reps doubling up
    Next touchDate and channelNo record without a next step
    OwnerOne named repOne owner per account
    Opt-out flagNoOnce set to yes, it never resets

    Do not skip the touch count. Without it you cannot tell a dead prospect from one the sequence gave up on too early. One or two messages will not do it; I plan at least 5 to 6 touches per prospect, on more than one channel where I can.

    The third follow-up often brings the reply in our campaigns. That holds when real time separates it from the second. If your records show most prospects stopping at touch 2, the sequence ended before replies usually arrive.

    Keep fit and engagement as two separate scores. HubSpot's lead scoring tool does the same, splitting fit, based on details such as role, firm headcount or yearly revenue, from engagement, based on actions the contact takes (HubSpot lead scoring). A high-fit prospect with no engagement needs more touches. A low-fit lead with high engagement gets a polite no.

    I put every prospect in a CRM, and which one barely matters. What matters is that nobody slips through.

    Are you allowed to hold and email prospect data?

    The data source, lawful basis and opt-out fields in the template exist because of the rules below. Here is a short summary of official guidance for the three markets my team writes to most. It is not legal advice.

    MarketWhat the official source saysFields your record needs
    UKThe ICO's B2B marketing guidance: PECR does not cover corporate subscribers. You must still name yourself and give an opt-out. Sole traders and some partnerships count as individuals, so you need their consent or a soft opt-in first. UK GDPR applies to personal addresses like initials.lastname@company.com, not info@company.com. Data from another source needs privacy information within one month. An objection must be honored.Subscriber type, lawful basis, data source, opt-out flag
    EUGDPR Article 6(1)(f) makes legitimate interests a lawful basis unless the person's rights override it. Under Article 14, if the data did not come from the person, you tell them its source and the interest you pursue, at the latest at first contact.Data source, lawful basis, interest pursued, date of first contact
    USThe FTC's CAN-SPAM guide gives business recipients no carve-out. Every message needs a valid postal address and honest headers. You have 10 business days to act on an opt-out, a single violating email can cost up to $53,088, and outsourcing the sending still leaves you liable.Opt-out flag with date, sender postal address

    The ICO page says its B2B guidance is being reviewed after the Data (Use and Access) Act, so reread it before you build a UK process on this summary. The EU row is also why the data source field carries a date: you cannot tell someone where their data came from if nobody wrote it down.

    Most of my team's outreach goes to the USA, the UK and Europe. When a prospect sits in Germany, Austria or the Czech Republic, I keep the first touches on LinkedIn, and cold email waits until a compliant basis is on the record.

    If your EU basis is legitimate interests, put the reasoning in writing before the first send. You can adapt this worked legitimate interest assessment example for cold email.

    What to change in your CRM tomorrow

    Write one entry rule per stage. Add a fit check, so no name counts as a prospect until it passes. Get the labels right first. Then scale the list. Not the other way round. Once the labels are right, outbound prospecting is the next step.

    Not sure where your CRM draws the line between prospect and lead? Book a call and share your stage names. We will map them to one entry rule per stage.

    Questions founders ask about prospects

    When should you drop a prospect from your list?

    Drop them for good the moment they opt out, and flag the record so no future list import brings them back. Someone who finished the full sequence without replying is better parked than deleted, because buyers and budgets change. In Dynamics 365 you can disqualify a lead only when no opportunity is attached, and a disqualified lead can be reactivated with its notes intact.

    What does "prospect email" mean?

    It is the first email to someone who fits your ICP but has never heard from you. Log it as a touch in the record, with its date and channel. Send it from a mailbox you can answer on, to an address you verified first.

    Can a past customer become a prospect again?

    Yes. A customer who left two years ago, or whose buyer moved on, often needs the same fit check and a fresh first touch as anyone new. Watch the CRM here: HubSpot's automatic lifecycle updates only move a record forward, so moving a former customer back to an earlier stage means clearing the value by hand or with a workflow.

    Is a referral a prospect or a lead?

    It depends on who acted. If a customer mentions a peer who might need you, that peer is a suspect until you check fit, and a prospect after. If the peer contacts you or agrees to talk, they are a lead.

    Put the referrer's name in the data source field, so the first line of the message can name who introduced you and the record shows why this contact was added.
