CRM for agencies: which CRM to choose in 2026?

Which CRM to choose for an agency?

A communication, marketing, media, or B2B services agency does not necessarily need the CRM with the most features. Above all, it needs a system simple enough to actually be used and structured enough to track companies, contacts, and opportunities.

Pipedrive is relevant when the primary need is to structure a pipeline, track next steps, and prevent opportunities from stalling. For a small sales team with a relatively linear cycle, this simplicity can be a real advantage.

HubSpot makes more sense when acquisition, marketing, and sales need to operate within the same environment. An agency that actually uses forms, nurturing, marketing campaigns, and CRM can find an interesting continuity there. If the need is simply to track a few dozen opportunities, however, the ecosystem may be broader than necessary.

Sellsy answers a different logic: bringing CRM and commercial management closer together. For an agency looking in particular to smooth the transition between opportunity, quote, and invoicing, this can weigh heavily in the choice.

Attio is interesting when you want to keep the logic of a real CRM while further adapting the data model and workflows to how the agency operates.

Airtable, finally, becomes especially relevant when sales and operations are highly intertwined. You can link clients, contacts, opportunities, missions, or deliverables in the same system. But this freedom implies more design and maintenance: if a specialized CRM properly covers the need, there is no need to rebuild it.

We detail this case in our guide on creating a custom CRM with Airtable.

The real challenge: linking CRM, delivery, and client development

In an agency, the cycle does not stop at signing.

Rather, it looks like:

Prospecting → Qualification → Opportunity → Signature → Delivery → Renewal / expansion → new opportunity

This continuity is important because a portion of an agency's growth often comes from already existing clients: a new mission, scope extension, renewal, or a need detected during delivery.

The CRM must therefore be able to track future sales resulting from the client relationship, without, however, becoming the tool in which all production is managed.

This is where many systems become fragile.

When a deal is won, the Ops team sometimes manually recreates the client or mission in another tool. The amount is transmitted, but the scope sold, the interlocutors, the constraints, or certain information discussed during the sale remain in emails, a quote, or in the sales representative's head.

The problem is not necessarily the CRM or the project tool. It is the transition between the two.

Conversely, trying to centralize everything in the CRM quickly poses another difficulty. You start adding tasks, deliverables, resources, validations, or scheduling. The CRM becomes harder to use on the Sales side without actually becoming an excellent production tool.

The right boundary generally consists of transmitting to delivery only what it needs to start properly: client, interlocutors, offer sold, scope, budget, dates, and useful context.

Then, the direction of the flow can reverse.

A mission coming to an end, a newly identified need, or a scope extension can become sales signals. When a need becomes sufficiently concrete, it can return to the CRM as a new opportunity with a potential amount, a deadline, and an owner.

Delivery remains responsible for execution. CRM remains responsible for present and future opportunities.

It is this loop that prevents losing expansion opportunities without turning the CRM into a project management tool.

CRM alone, Airtable alone, or CRM + Airtable?

The right choice depends mostly on the respective complexity of sales and delivery.

A CRM alone may suffice when an agency already has a production tool that works properly. Attio, Pipedrive, or another CRM manages the relationship and the pipeline, then some information is transmitted to the delivery system when an opportunity is won.

There is then no reason to rebuild operations.

Airtable can become the common foundation when sales and delivery are so intertwined that separating them mostly creates double entry. A small agency can, for example, link:

Clients ↔ Contacts ↔ Opportunities ↔ Missions ↔ Deliverables

Sales representatives have an interface focused on their pipeline while Ops work on missions using the same data.

This architecture is relevant when these relationships are truly part of the business operations. It is much less so when simply trying to track sales opportunities.

Attio + Airtable becomes interesting when Sales and Ops are each sufficiently structured to justify their own system.

Attio can then carry companies, contacts, opportunities, and sales workflows. Airtable carries missions, production, and other operational processes.

At the time of closing, only the necessary information is passed to Airtable. When a sales need appears during delivery, a new opportunity can be created or escalated in Attio.

The goal is not to fully synchronize both tools.

The more data you duplicate, the more you create risks of divergence and maintenance.

The best architecture is therefore generally the simplest one that allows the right information to flow at the right time.

How to structure a CRM that is actually adopted in an agency?

The choice of software matters, but a poor architecture will remain a poor architecture in any tool.

For many B2B agencies, the initial model can remain simple:

Companies + Contacts + Opportunities

It is not necessary to create an object for every peculiarity of internal operations right from the start.

The pipeline must also correspond to events understandable by the whole team.

Stages like In Progress → Interested → Hot rely heavily on interpretation.

Qualification → Discovery → Proposal → Negotiation → Won generally allows for a better understanding of what actually happened and what should follow.

The transition between sales and delivery must then be designed from the start. At what point is the mission created? In which tool? What information is transmitted? Who becomes responsible?

The same logic applies in reverse: at what point does a need escalated by delivery become a real sales opportunity?

Only once these rules are clear does it become useful to automate the creation of a mission, the transmission of context, notifications, or the creation of an expansion opportunity.

Automating an ambiguous process does not make it better. It simply allows you to execute faster something that is not yet clearly defined.

Finally, you have to accept that the CRM will evolve with its use. Some fields will turn out to be useless, some stages too close, and some data will be missing.

It is better to start simple and improve the system based on actual use rather than trying to cover every possible case from day one.

For this type of project, our support in CRM implementation starts with the processes and the data model before choosing the tool and the necessary automations.
