I say this as someone who has worked in an agency and now works as an independent consultant: there is no answer that is valid for everyone, but there are concrete criteria to understand which of the two paths is right for your company at this moment.
What really changes: it is not (only) the price
The criterion by which many companies choose is price, but it is the least useful one for deciding well. The right question is: how many different skills do I need in parallel, and how much does it matter to me to always speak with the person who does the work, instead of with an account manager who acts as an intermediary?
The advantages of an agency
- Multiple skills under one roof: the people who write the copy, create the graphics and manage the campaigns are often different, specialized people.
- Guaranteed continuity even if a single team member is sick or on holiday.
- More structured processes, useful if your company needs formal reporting and defined procedures.
The advantages of a freelance consultant
- A direct relationship: you always speak with the person who analyzes the data and sets up the campaigns, not with an account manager who reports to someone else.
- Faster decisions: no internal handoffs between departments before an answer or a change.
- Often a lower cost, because there is no structure with multiple levels to support.
- Flexibility in how you work, without having to adapt to a standard process designed for many different clients.
The questions to ask yourself before choosing
Do you only need campaign management, or also continuous creative production (videos, graphics, copywriting)? In the first case a specialized freelancer may be enough; in the second, an agency or a freelancer who coordinates external suppliers becomes more suitable. How much do you need to be involved in day-to-day decisions? If you want an almost weekly and direct relationship, a freelancer responds better to this need than a larger structure.
A third way: the consultant as external marketing direction
For companies that do not need massive creative production but want someone to think about the overall strategy, not just the campaigns, there is a middle way: a consultant who coordinates the suppliers already present in the company (creative agency, developers, print) while keeping the strategic direction, without replacing them. It is a model that combines the cross-functional expertise of an agency with the direct relationship of a freelancer.
