How a GTM agency builds an SME sales engine in 90 days

A GTM agency builds an SME sales engine in 90 days not by tackling everything at once, but by working in three phases: lay the foundation, fill the pipeline, prepare the handover. Go-to-Market (GTM, the whole path from your offer to a paying customer) does not mean a giant tooling project here. It means a lean CRM, two or three focused channels and a few clean routines. That is genuinely achievable in a single quarter, even with a small team.

This article shows what such a 90-day plan looks like in practice, with Swiss SME scenarios, CHF figures and a simple CAC calculation (CAC = Customer Acquisition Cost, the cost of winning one customer). It also explains why software removes friction while selling stays human.

Why 90 days, and not 12 months?

Ninety days is short enough to stay disciplined and long enough to see real results. An SME does not want a strategy that only pays off in a year. It wants the first qualified conversations this quarter and a system that keeps running afterwards.

A good GTM agency therefore works in clear stages rather than one big bang. Each phase has a measurable goal and an artefact that stays behind: a defined customer profile, a filled pipeline, a documented process.

If you want the bigger picture first, read our overview of Go-to-Market for Swiss SMEs. This article turns that into a concrete roadmap.

What happens in the first 30 days?

Phase 1 is foundation. Nothing is sold here yet, the work is preparation, but at pace. The goal is clarity about who you want to win, with what message, and through which tool.

• Sharpen the ICP. The ICP (Ideal Customer Profile) describes which companies fit best: industry, size, trigger, budget. Stay broad here and you will burn time later.
• Tighten the offer. A clear statement of which problem you solve, and at what price.
• Set up the CRM. A lean CRM with few fields, clear pipeline stages and simple task logic.
• Choose channels. Two or three channels, not ten. For example personal email outreach, LinkedIn and an existing network.

For the ICP work, our guide to a lean GTM strategy on a low budget offers practical levers. A sharp ICP is the lever for everything that follows.

Scenario: a fiduciary office in Zurich

A fiduciary office with eight staff wants to win mandates from growing startups. In phase 1 the agency defines the ICP: tech startups in Zurich and Zug, 5 to 30 employees, shortly after a funding round. The offer: monthly bookkeeping plus payroll administration from CHF 1'200.00 per month.

Instead of a broad list of 600 names, a focused list of 90 genuinely relevant companies emerges. The CRM is set up with four pipeline stages: Contacted, Conversation, Proposal, Won.

What happens on days 31 to 60?

Phase 2 is pipeline. Now you execute: outreach, conversations, follow-up. The CRM stops being an empty shell and becomes a working tool.

1. Start outreach. Personalised outreach in small waves, not an anonymous mass blast.
2. Hold conversations. This is where selling stays human: listening, timing, clarity. Software only supplies the context.
3. Follow up consistently. Most deals close on the third or fourth touch, not the first.
4. Measure. Reply rate, conversation rate, proposal rate, so you know where things stall.

AI assists usefully in this phase: it suggests wording, summarises notes and reminds you to follow up. It does not decide who gets called, and it does not hold the conversations. That stays with people.

Scenario: a web agency in Bern

A five-person web agency in Bern wants a more predictable flow of projects. In phase 2 it contacts 60 fitting SMEs with a concrete offer: a website relaunch package from CHF 9'500.00.

Of 60 contacts, 15 reply, leading to 7 conversations and 3 proposals. The point is not the number itself, but that every step is visible in the CRM, and that nothing slips through the cracks.

What happens on days 61 to 90?

Phase 3 is handover. The agency works itself out of the daily routine so the SME can carry on independently. This is exactly what separates a good GTM agency from one that just delivers meetings and disappears.

• Document the process. Who does what, when, in which pipeline stage.
• Enable the team. One or two people at the SME are trained on the CRM and the conversation guide.
• Anchor routines. A weekly 30-minute pipeline check is often enough.
• Setup and handover. The agency hands over a working system, not a bundle of loose notes.

Optionally the agency stays on board as ongoing support, as GTM-as-a-service. That is attractive for both sides: the SME has reassurance, the agency has predictable recurring revenue.

What does the CAC calculation look like?

A simple CAC calculation helps you judge the effort realistically. Take the web agency from Bern.

Assumptions for one quarter:

• Agency fee for the GTM build: CHF 12'000.00
• CRM (lean, small): around CHF 90.00 per month, so CHF 270.00
• Own selling time (valued): CHF 6'000.00

Total effort: CHF 18'270.00. This produces 3 new customers in the quarter.

That gives a CAC of roughly CHF 6'090.00 per customer. With a project value from CHF 9'500.00 and the prospect of follow-on work, that is sustainable, provided the system keeps running after the 90 days without an expensive retainer. That is exactly the point of the handover.

Which CRM fits, HubSpot or something lean?

Large platforms like HubSpot are strong, no question. They offer a great deal and scale far upward. For a marketing team with its own operations profile, they can be exactly right.

Most Swiss SMEs, however, do not need a whole platform universe in their first 90 days. They need a lean CRM that is instantly understandable, plus a few focused channels. The comparison below shows the typical trade-off.

For a deeper look at the options, see our comparison of GTM models. The rule of thumb: start lean, and only grow into more complexity once the need is genuinely there. You can also browse the functions to see what a lean CRM actually covers.

How does an agency do this across several clients?

For agencies the 90-day approach is more than a project, it is a business model. With a repeatable setup, you can roll it out across many clients.

• Repeatable playbook. The same phase logic for every client, only the ICP and offer change.
• Multi-client overview. Several pipelines kept cleanly separate, but in the same simple system.
• Recurring revenue. Setup-and-handover can turn into ongoing support.
• Faster results. With practice, 90 days per client becomes a well-rehearsed routine.

Advanzo supports exactly this model: a lean, understandable CRM that an agency can set up at a client, fill and then hand over, with data that stays in Switzerland.

Common mistakes

Most 90-day plans fail not on strategy but on execution. These are the mistakes we see again and again.

• An ICP that is too broad. Trying to reach everyone reaches no one properly.
• Too many channels. Ten half-hearted channels never beat two consistent ones.
• Tooling before clarity. A complex CRM does not fix a fuzzy offer.
• No follow-up. The first touch is rarely the one that closes.
• No handover. If only the agency can run the system after 90 days, you built a dependency, not an engine.
• Measuring nothing. Without rates, no one knows which pipeline stage is stalling.

Frequently asked questions

Do you really need an agency for 90 days?

No, not necessarily. An SME with time and discipline can run the plan itself. An agency mainly brings pace, routine and an outside view, and makes sure the build does not get buried by day-to-day work.

Roughly what does a 90-day build cost?

It depends heavily on scope. Realistically, fees for a focused build range from a few thousand up to around CHF 15'000.00, plus the low CRM cost. What matters is that you end up with a system you can run on your own.

What happens after the 90 days?

Ideally sales keeps running on its own, carried by a documented process and a weekly pipeline check. Some SMEs keep the agency as ongoing support, others take over fully themselves.

Does AI replace selling?

No. AI assists: it summarises, suggests wording and reminds you to follow up. The relationship, the timing and the feel for the right moment stay human.

How many channels make sense?

In the first 90 days, two or three consistently worked channels are enough. More channels mean more spread and less depth, which is counterproductive early on.

Does our data stay in Switzerland?

With a CRM built for the Swiss market like Advanzo, the data stays in Switzerland. For many SMEs and their clients, that is an important trust criterion. You can review the details on pricing and the integrations page.
