What each one does
A marketing agency works before the lead exists: audience, creative, channel, media. Its success is measured in lead volume and cost per lead.
A sales consulting firm works after the lead exists: process, approach, funnel, team. Its success is measured in conversion rate and how organized the operation is.
Marketing integrated with sales covers the border between the two: it runs acquisition already connected to the CRM and the sales process, so the lead arrives logged and is worked all the way to the close. Its success is measured in sales.
Sales consulting, agency and marketing integrated with sales, side by side
The table sums up where each model works and how each one should be held accountable. It doesn't point to a winner: it points to which one fixes which bottleneck.
| Criterion | Sales consulting | Marketing agency | Marketing integrated with sales |
|---|---|---|---|
| What it delivers | A redesigned sales process: stages, exit criteria, CRM usage, routine and metrics | Demand: campaigns, creative, content and media on the right channels | Acquisition run and connected to sales: media, landing pages, tracking and CRM |
| Where it works in the funnel | From lead to close | Before the lead: attention, interest and capture | From click to cash, across the handoff from marketing to sales |
| How it measures results | Conversion rate between stages, sales cycle, predictability | Lead volume, cost per lead, reach | Sales, revenue and acquisition cost by campaign and by channel |
| When it makes sense | Leads come in and don't turn into sales, or do so unpredictably | Sales converts well, and what's missing is volume at the top | Nobody knows which campaign became a sale, or paid leads go cold before a sales rep gets to them |
| What it doesn't fix | Lack of demand: reorganizing the funnel doesn't create leads | Conversion: more media on top of a sales team that doesn't respond amplifies the waste | An operation with nobody to sell: someone still has to handle the incoming lead |
How to know which one you need
A simple test settles most cases: do you have enough leads and can't convert them, or do you not have leads?
If sales can't keep up with what's already coming in, more media makes the problem worse — it increases waste. If the process is sharp and demand is missing, sales consulting doesn't generate demand.
- Leads come in and go cold without a reply → a sales problem
- Few leads, but the ones that come in convert well → an acquisition problem
- Leads come in, but nobody knows which campaign they came from or which ones became sales → a problem in the link between marketing and sales
- You can't answer the question above → a measurement problem, which comes before all three
The signs of each bottleneck
Before hiring, it's worth looking at the operation during an ordinary week. The symptoms are usually specific enough to point the way:
- Sales bottleneck: the first reply to a lead takes hours, follow-up depends on the sales rep's memory and results change depending on who's on the team
- Acquisition bottleneck: the team's calendar has room to spare, the few leads that come in close well and volume doesn't grow even with the team available
- Bottleneck between the two: marketing says it delivered leads, sales says the leads are bad, and neither side has a number to settle the argument
When the agency is the right choice
When the sales operation already works: there's a process, the team replies quickly, the funnel is reliable and the real bottleneck is volume at the top. In that scenario, a good agency delivers more return than any internal restructuring.
When sales consulting is the right choice
When demand exists and gets lost along the way: the lead comes in and waits, each sales rep runs the sale differently, the CRM doesn't reflect the operation and the target is hit or missed without anyone being able to explain why. In that scenario, investing more in media increases the volume of wasted leads, and the cost of each sale goes up.
Sales consulting deals with the structure that receives the lead — funnel stages, exit criteria, response time, record-keeping and a metrics routine. Once that's in place, every bit of ad spend goes further, because what comes in gets answered and followed up.
What happens when you hire the wrong one
An agency hired for a sales problem delivers what it promises — more leads — and the result doesn't show up. The usual conclusion is that "marketing doesn't work for our business", when the loss was in how leads were handled.
A consultancy hired for a demand problem organizes a funnel that stays empty. The process looks great, the team is trained, and revenue doesn't move because there's nothing to convert. In both cases the money wasn't lost on the vendor: it was lost on the question nobody asked beforehand.
Where Nexo stands
Nexo is neither a standalone agency nor a traditional consultancy. Classic consulting delivers an assessment and a plan, and execution is left to the client. Nexo builds and operates the structure — with proprietary software.
Nexo does marketing, but never separate from sales: it plans and runs acquisition — media, landing pages, tracking — already connected to the CRM and the sales process, and measures results in sales, from click to cash. When the client already has an agency, the media can stay with it and Nexo instruments the path from click to cash; when there's no agency, Nexo runs acquisition together with the CRM and the sales process.
