We have seen the same conversation in three industries this quarter. The board says: let us hire a Chief Digital Officer instead of paying consultancy. The CFO says: it is the same money. The CEO has to decide. The math is more interesting than either side admits.
The classic in-house decision compares an annual full-time C-level salary in Colombia of USD 150K to USD 250K, including benefits, against a consulting engagement priced in tens of thousands. Stated like that, in-house wins. Stated honestly, the comparison is wrong because it leaves out four cost components that change the answer.
What in-house actually costs
Component one: time to productivity. A senior C-level hire in mid-market in Latin America typically takes six to nine months to deliver compounding output. That is not because the hire is slow. It is because they have to learn the company, the market, the team, the legacy, the politics. During those six to nine months, you are paying salary without getting strategic output yet. That is a USD 75K to USD 190K opportunity cost embedded in the salary line that does not show in the budget.
Component two: hiring search cost. A senior strategic hire in this segment runs through two to four executive search processes, each with a fee of 25% to 33% of annual salary. Even if you find the right person on the second attempt, the search cost alone is typically USD 30K to USD 80K.
Component three: team structure. A C-level alone does not execute. They need a small support team. Two to four people. Add another USD 200K to USD 400K annually.
Component four: exit risk. If the hire does not work out at month nine, you have a severance liability and a strategic gap to fill. The probability of mismatch on a senior strategic hire in mid-market is significant. The expected cost of that risk, run probabilistically, is usually USD 40K to USD 100K.
Total true cost of an in-house C-level in year one: USD 410K to USD 920K. Not the USD 150K to USD 250K that appears in the salary line.
What an integrated external engagement costs
An integrated consulting engagement that delivers strategy, technical execution, fractional senior capacity and applied R&D under a single team typically prices in the USD 100K to USD 350K range over 6 to 12 months, depending on the scope. The output is compounding from week one because the team has done the work before, in similar contexts, in this region.
The honest comparison is: USD 410K to USD 920K of in-house in year one with output starting at month six, versus USD 100K to USD 350K external with output from week one. The math is not close.
The right question is not whether in-house is better. It is whether you have time to wait six to nine months before strategic output begins.
When in-house is actually the right call
In-house wins in three specific cases. First, when the strategic capability you need is permanent and central to the business model. A retail company that fundamentally needs a permanent Head of Data Science in-house. Different conversation.
Second, when the company is large enough that the embedded costs distribute across enough operations to be invisible. A USD 300M revenue company hiring a CDO is buying a different unit economic profile. Mid-market is not in that bucket.
Third, when the in-house hire is a former operator from a comparable mid-market company who can demonstrate compounding output in the first 90 days. Those people exist. They are rare. They cost more than the typical hire because their compression of learning curve has real value.
If none of those three conditions apply, the math points to external. The exception is the rule, not the other way.
What to do this quarter
Run the honest math before the next board meeting. Add the four embedded cost components to the salary line. Compare the total to a defined external engagement scoped to your specific outcomes. If the external option still loses, in-house is the right call. If the math flips (which it usually does), the conversation should change.
The board that defaults to in-house without running the math is not making a financial decision. It is making a comfort decision. In mid-market, comfort is expensive.
