Two definitions of a good lead
Marketing and sales often use the same word for two different things. For marketing, a good lead is one that comes in at a workable cost, with the right job title, from the right country. For sales, a good lead is one that can and will make a decision within a reasonable window. Those aren't synonyms.
A lead can score perfectly on every marketing criterion and still be useless to sales: someone doing research for a report, with no budget and no mandate. Conversely, a lead marketing would filter out as noise can be the most valuable contact of the week for sales, for instance someone who arrived through a generic search term but has to decide tomorrow.
The problem isn't in either definition, it's that the two were never laid side by side. Without an agreement, marketing optimizes for its own definition, sales builds its own filter on top, and everything that falls between the two filters disappears. That's not a quality problem with the leads, it's a definition problem nobody has solved.
What needs to travel with a lead
A lead that reaches sales with just a name and an email address arrives without context. Sales then has to reconstruct who this person is, and that eats into the time available for response. These fields should travel by default, regardless of the CRM:
- Source: the platform the lead came from, with campaign name and ad group or ad set, not just "Meta" or "Google"
- Form or landing page: the exact page and form, including version if you're testing
- Timestamp: date and time of submission, since that's when the response clock starts
- Form answers: every field the lead filled in themselves, verbatim
- UTM parameters: source, medium, campaign, content, so nobody has to guess
- Device: mobile or desktop, since that often hints at whether someone glanced on the go or compared options deliberately
If any of these fields is structurally missing, that's not a minor technical gap: nobody can say with certainty which campaign drove a sale, and every budget decision becomes a guess from that point on.
Response time matters more than quality
A lead filling out a form is often comparing several vendors at the same moment. Whoever responds first, personally, usually starts the conversation with an advantage that is hard to catch up on later. The longer it takes, the colder a warm lead gets, regardless of how good the sales call turns out to be. That explains why comparable leads turn into conversations at one company and sit untouched at another.
That's why response time doesn't belong in a "best practices" doc, it belongs in the handover agreement itself: a hard limit in minutes for the first attempt, and a set number of follow-up attempts over the following days. Without that limit, a lead sits in a queue that stays invisible until you line up the numbers a quarter later.
Ownership: who sees what, and from when
A lead without an owner is a lead nobody follows up on, even if it sits neatly in the system. That gap appears because ownership stays implicit: marketing assumes sales took over once the lead hit the CRM, sales assumes marketing is still filtering. So spell out explicitly at which moment ownership transfers, and what happens if the receiving side doesn't respond. Marketing stays owner until the lead meets the agreed criteria. Sales becomes owner once it explicitly accepts the lead, not the moment it arrives. If sales doesn't respond within the agreed window, ownership automatically reverts to marketing, which then decides whether to re-offer the lead or handle it separately.
Signals a lead is unusable, before sales spends time on it
Not every lead deserves a phone call. A few signals you can spot before anyone invests time:
- A free email provider when the company itself has its own domain
- A phone number that doesn't match the stated country
- A job title with no decision authority, paired with a question that assumes decision authority
- A form filled out completely within a few seconds
- A company name matching a known competitor, not a real prospect
- Identical answers to open questions as another lead from the same period
One such signal doesn't automatically make a lead worthless, but it earns a faster, cheaper check before it gets the same full treatment as every other lead.
The feedback loop that's usually missing
Marketing optimizes for what it can measure: forms, cost per lead, volume. If sales never reports back which leads turned out to be real opportunities, marketing keeps optimizing that one signal, even if it produces the wrong leads. That's not sales being unwilling, it's a loop that was never set up, and a loop that isn't set up doesn't happen on its own.
The handover agreement
This is the document you can fill in today and share with your sales team or agency. Copy it, fill in the blanks, and set it next to your next lead report.
Marketing-to-sales handover agreement
What counts as a transferable lead. Criteria: _______. Alarm: nobody can name these without checking the CRM.
Fields that always travel. Source, campaign, form, timestamp, answers, UTM parameters, device. Alarm: one field is structurally missing.
Response time for the first attempt. Within _______ minutes of receipt. Alarm: the answer comes in hours or days, not minutes.
Number and spread of attempts. _______ attempts over _______ days, across _______ channels. Alarm: one attempt, then silence.
Moment of ownership transfer. Marketing hands off once _______. Sales accepts within _______. Alarm: nobody can point to the exact moment ownership changes.
Fallback rule. If sales doesn't respond within the agreed window, then _______. Alarm: this rule is missing, so slow leads vanish quietly.
Disqualification criteria before follow-up. Which signals are enough to set a lead aside: _______. Alarm: every lead gets the same full treatment.
Feedback from sales to marketing. Status per lead, at least _______ times per _______, with a reason when rejected. Alarm: this step is missing, marketing steers blind on cost per lead.
Owner of this document. Name: _______. Review date: _______. Alarm: neither field is filled in.
For illustration, entirely fictional: at a made-up company called "Noordkaap B2B," filling in point 3 revealed that nobody dared name a number. The first attempt happened "whenever someone had time." That conversation alone, before anything changed, exposed where revenue was leaking between marketing and sales.
How to read the result
Fill in the document with your whole team, not just from marketing: a document marketing fills in alone is a wish list, not an agreement. Count how many of the nine points get a concrete answer instead of "we handle that case by case." Three or more vague answers signals the handover currently runs on habit, not agreement. That's normal for a first pass. It becomes an alarm if the same document still has the same blanks six months later.
The next step
This document doesn't fix anything the moment it's filled in, it only makes visible where the conversation hasn't happened yet. Put it in front of your sales team or agency this week, fill it in together, and watch which point stalls the longest. That's the one you start on tomorrow.
