El aprovechamiento mejorará a poco que revisemos las existencias.

In this sentence, aprovechamiento means something like efficiency, usefulness, yield, or how well resources are being used.

It comes from aprovechar, which often means to make good use of or to take advantage of something.

So el aprovechamiento mejorará suggests that the overall use or performance will improve. The best English equivalent depends on context:

• in business: efficiency or output
• in education: performance
• in resource management: utilisation or use

A poco que is a set expression meaning roughly:

• if we so much as...
• provided we... even a little
• with just a little...
• as long as we... to some extent

So a poco que revisemos las existencias means something like:

• if we just review the stock
• with even a minimal review of the inventory
• provided we do even a little checking of the stock

It often suggests that only a small effort is needed for the result to happen.

Because a poco que normally triggers the subjunctive.

The idea is not stating a fact, but a condition:
if / provided that we review the stock

So:

• revisemos = present subjunctive of revisar
• subject = nosotros

This is similar to other Spanish structures where a condition or uncertain event takes the subjunctive.

Mejorará is the future tense: will improve.

The sentence is talking about a result that will happen after or if the stock is reviewed. So the future is natural here.

Comparisons:

• mejora = improves / is improving
  more immediate or general
• mejorará = will improve
  points to a future consequence
• mejoraría = would improve
  more hypothetical or less definite

So this sentence presents the improvement as a likely future result.

Existencias usually means stock, inventory, or supplies on hand.

In business or logistics Spanish, it often refers to the goods currently available in storage.

So revisar las existencias means:

• to check the inventory
• to review stock levels
• to inspect what is in stock

In other contexts, existencias can also mean supplies or available quantities.

Spanish often uses the definite article more than English does.

So revisar las existencias is perfectly normal, even where English might simply say:

• review inventory
• check stock

Using las does not necessarily mean those specific stocks in a strongly emphatic way. It often just refers to the inventory in question, the stock relevant to the situation.

It is correct and fairly standard, but it sounds a bit more formal, written, or elevated than the most basic everyday phrasing.

In more everyday Spanish, people might say things like:

• Si revisamos un poco las existencias...
• Con solo revisar las existencias...
• Basta con revisar las existencias...
  depending on the exact nuance

So learners should understand a poco que, but may hear simpler alternatives more often in casual speech.

Yes, depending on context.

Aprovechamiento can refer to:

• the use of resources
• productivity
• educational performance
• benefit obtained from something

For example:

• aprovechamiento escolar = academic performance
• aprovechamiento de recursos = resource utilisation

In your sentence, because of revisemos las existencias, it most naturally sounds like efficiency in managing stock or resources, not school performance.

A close breakdown is:

• El aprovechamiento = the efficiency / utilisation / yield
• mejorará = will improve
• a poco que = if only / provided that / with just a little
• revisemos = we review
• las existencias = the stock / inventory

Very literally: The efficiency will improve if we so much as review the inventory.

That sounds a bit stiff in English, but it helps show how the Spanish is built.

Not really. That would change the meaning.

• a poco que revisemos = if we just review / provided we review even a little
• en cuanto revisemos or tan pronto como revisemos = as soon as we review

So a poco que is about a small condition being enough, not about timing.

It would be similar, but not exactly the same.

• Si revisamos las existencias, el aprovechamiento mejorará.
  = If we review the inventory, efficiency will improve.
• El aprovechamiento mejorará a poco que revisemos las existencias.
  = Efficiency will improve if we even just review the inventory.

The second version adds the nuance that only a small effort is needed. It sounds more idiomatic and slightly more expressive.

The chosen word order is natural and helps emphasise the result first:

• El aprovechamiento mejorará → the main point
• a poco que revisemos las existencias → the condition

You could also say: A poco que revisemos las existencias, el aprovechamiento mejorará.

That version puts the condition first, which is also correct. The meaning stays basically the same, but the focus shifts slightly:

• condition first = more emphasis on what needs to be done
• result first = more emphasis on the expected improvement
