In many companies, marketing and sales are two separate worlds. They have separate teams, separate budgets, separate goals, separate meetings, and sometimes even separate definitions of what constitutes a good customer. Marketing is supposed to build interest and deliver leads. Sales is supposed to take over those leads, guide them through the process, and convert them into revenue.
On paper, this division looks logical. Since marketing is responsible for the top of the funnel and sales for the rest of it, all that is needed is a smooth handover of customers at the right moment.
Except the customer doesn’t move from marketing to sales.
The customer is simply trying to make a decision.
The customer doesn’t see our departments
Imagine a person who starts looking for a solution to a specific problem. First, they type something into Google. They land on a company’s article. A few days later, they see its ad. They visit the website, read the offer, watch a video, check reviews, and perhaps sign up for a webinar. Only after some time do they speak with a sales rep.
From the company’s perspective, a lot of things might have happened. Marketing generated traffic, a campaign generated a lead, someone assigned the contact to the right segment, then the lead was handed over to sales, a sales rep made a call, a meeting took place, and an offer was created.
From the customer’s perspective, only one thing happened: they interacted with one company.
They don’t care which department wrote the article, who set up the ad campaign, or who later sent the offer. They also don’t know exactly where the boundary between marketing and sales lies. And, quite frankly, there is no reason for them to know it.
This distinction is important because the way a company organizes its own work doesn’t have to match how the customer experiences the buying process.
Furthermore, the modern B2B journey is becoming increasingly non-linear. Customers use multiple channels, gather information independently, and bounce between digital touchpoints and human interactions. Gartner describes this process as a non-linear buying journey, and McKinsey, in its 2026 B2B study, points to an average of ten channels used by buyers during a purchase.
If the customer navigates between channels, why should the company organize itself as if they were navigating between departments?
Marketing might deliver leads that sales doesn’t even need
This is where one of the most well-known problems in marketing and sales collaboration arises.
Marketing says: we generated a lot of leads.
Sales replies: most of them are worthless.
So marketing increases the number of campaigns and leads. Sales continues to complain about their quality.
This doesn’t necessarily mean that either team is doing their job poorly. It’s quite possible that both teams are performing exactly as they are incentivized to.
If marketing’s goal is lead volume, it will look for ways to increase that number. If sales’ goal is revenue, it will be primarily interested in those contacts that have a high chance of closing.
As a result, each team can improve its own metrics, while the company as a whole doesn’t necessarily improve its business outcome.
This is an example of a problem that occurs very often in organizational management: local optimization does not necessarily lead to the optimization of the entire system.
Marketing might lower the cost per lead. Sales might increase the number of closed deals. Both results might look good, yet revenue can still grow slower than it should.
Therefore, the problem doesn’t always lie in a lack of collaboration. Sometimes it lies in the fact that two teams were designed to optimize two different segments of the exact same process.
The funnel doesn’t have two parts
A popular picture looks something like this:
marketing → lead → sales → customer
Such a model is convenient because it allows accountability to be assigned. Marketing is responsible for the first part, sales for the second.
The problem is that the customer’s reality doesn’t necessarily look that way.
A customer might discover the company through marketing, independently read a few materials, later talk to a sales rep, return to the website, watch a demo recording, compare the offer with competitors, and only then make a decision.
Moreover, a conversation with a sales rep can generate new informational needs. After a meeting, the customer might go back to educational materials, look for additional information, or require content that will help them convince other members of the buying committee.
In such a world, it is hard to pinpoint a single moment where marketing ends and sales begins.
Of course, you can establish such milestones for the organization’s sake. You can define MQLs, SQLs, opportunities, or subsequent pipeline stages. This is necessary if we want to manage the process and the data.
However, one should not confuse an organizational definition of a stage with a real moment in the customer’s decision-making process.
Just because a lead’s status in the CRM changed from marketing to sales doesn’t mean the customer just crossed some natural boundary.
Sales is also communication
The marketing-sales divide has one more consequence.
We often treat marketing as the function responsible for communicating value, and sales as the function responsible for “delivering” it to the customer.
Meanwhile, the sales rep communicates value as well.
Every conversation, presentation, answer to a question, or proposal influences how the customer understands the company and its solution. If marketing promises simplicity, but the sales rep presents a complicated implementation process, the customer doesn’t experience an “inconsistency between marketing and sales.”
They experience an inconsistency of the company.
The same works in reverse. Sales reps hear questions, objections, and arguments from customers every day that marketing might not see. If this knowledge doesn’t feed back into the communication strategy, the company loses one of the best sources of information on how customers truly perceive its offering.
Consequently, marketing crafts its messaging based on its own data, while sales conducts conversations based on its own experience. Both teams work with the customer, but they learn from them separately.
Therefore, the problem might not be a lack of collaboration, but the way accountability is designed
When marketing and sales don’t work well together, we often try to fix the situation with more meetings.
We set up SLAs.
We create MQL definitions.
We build a lead handover process.
We introduce shared dashboards.
We organize marketing and sales alignment meetings.
All of this might be necessary. However, it does not solve the fundamental problem if each team is still primarily responsible for its own segment of the path to revenue.
That is why the concept of Revenue Operations, or RevOps, is increasingly emerging. Its essence is not simply “better marketing and sales collaboration,” but rather looking at the revenue generation process as a single system encompassing marketing, sales, and—increasingly—customer success. In such an approach, data, stage definitions, processes, handover mechanisms, and some metrics become shared.
This is an important shift in perspective.
We are no longer solely asking: “how do we get marketing and sales to work better together?”
We are asking: “how do we design a system where both teams participate in revenue creation, but do not have to compete over which fragment of the process belongs to which department?”
It’s not about eliminating marketing and sales
Of course, marketing and sales can remain distinct functions. They require different competencies, different tools, and often different types of work. There is no need to prove that all these differences are artificial.
The problem arises when an organizational difference begins to be treated as a difference in the business process.
Marketing can be responsible for demand generation, communication, and nurturing interest. Sales can be responsible for managing sales opportunities and finalizing transactions. That still makes perfect sense.
But both teams should know how their work connects to the exact same process on the customer’s side.
They should also share, as much as possible, a common understanding of who the company wants to acquire, what a valuable customer looks like, what a qualified opportunity means, and what behaviors lead to a sale.
Otherwise, a company might end up with two well-functioning teams and one malfunctioning system.
The boundary between marketing and sales might be necessary for the company, but not for the customer
Perhaps that is why the question “where does marketing end and sales begin?” is somewhat misplaced.
The boundary might be needed by the organization. After all, we need to divide accountability, plan workflows, and assign competencies.
But from the customer’s perspective, something else is far more important: do consecutive experiences with the company form a cohesive whole?
Does the information they saw in an ad match what they read on the website?
Is the promise made by marketing communications validated during the conversation with a sales rep?
Does the sales rep know what the customer has already seen and what they were looking for?
Do the questions that arise during the sales process make their way back to marketing?
After the purchase, does the company continue to use the customer knowledge it gathered before the sale?
If the answer to these questions is “yes,” the boundary between functions ceases to matter to the customer.
And perhaps that is exactly the point.
Marketing and sales do not have to be a single department. They don’t have to possess the same competencies or perform the same work.
However, they should understand that they are working on a single process that does not begin in marketing and does not end in sales.
It begins the moment a need arises on the customer’s side.
And it ends long after the contract has been signed.
