En lugar de comprar otro lote, revisamos las existencias.

Because en lugar de is the fixed expression meaning instead of.

• en lugar de + noun / infinitive
  • En lugar de comprar... = Instead of buying...
  • En lugar de café, tomó té. = Instead of coffee, he/she had tea.

Without de, en lugar usually means something more literal, like in place or in a place/location, depending on context. So here, de is necessary.

Because after en lugar de, Spanish normally uses:

• a noun: En lugar de otro lote...
• or an infinitive: En lugar de comprar otro lote...

This is the same idea as English instead of buying. Spanish does not use a gerund here in the same way English does. So comprar is the natural form.

Yes. En vez de is very common and usually means the same thing as en lugar de.

So you could say:

• En vez de comprar otro lote, revisamos las existencias.

Both are correct.
Very generally:

• en vez de sounds a bit more everyday/conversational
• en lugar de can sound slightly more neutral or formal

But in most contexts, they are interchangeable.

Because otro normally does not take un/una before it in standard Spanish.

So:

• otro lote = another batch/lot
• otra opción = another option

Not:

• un otro lote ❌

This is a common difference from English, where another historically contains the idea of an + other. In Spanish, otro already does that job by itself.

Lote usually means lot, batch, or consignment, depending on context.

In business, warehouse, or inventory contexts, lote often refers to:

• a batch of products
• a production lot
• a grouped quantity of items

So comprar otro lote could mean:

• buy another batch
• buy another lot
• order another consignment

The best English translation depends on what is being bought.

Because existencias is a common Spanish business/inventory term that is normally used in the plural.

It means things like:

• stock
• inventory
• goods on hand

So:

• revisar las existencias = check the stock / review inventory

Even though English often uses singular-like mass nouns such as stock or inventory, Spanish commonly uses the plural existencias.

Spanish uses definite articles more often than English does.

Here, las existencias refers to the stock/inventory relevant to the situation, so the article sounds natural and expected.

Compare:

• Revisamos las existencias. = We checked the inventory/stock.

In English, we sometimes drop the article, but Spanish often keeps it.

Not usually in this kind of sentence. This is a classic false friend.

In Spanish, revisar often means:

• to check
• to inspect
• to review
• to look over

So here:

• revisamos las existencias = we checked/reviewed the stock

If you want revise in the sense of changing or improving a text, Spanish might use:

• revisar in some contexts
• corregir
• repasar
• modificar

It depends on what kind of revision you mean.

Yes. Revisamos can be either:

• present: we review / we check
• preterite: we reviewed / we checked

This happens with many -ar verbs in the nosotros form.

For example:

• Hoy revisamos las existencias. = Today we check/review the stock.
• Ayer revisamos las existencias. = Yesterday we checked/reviewed the stock.

So you need context to know which tense it is.

Because Spanish often leaves subject pronouns out when the verb already shows who the subject is.

• revisamos already tells you it is we

So:

• Revisamos las existencias.
• Nosotros revisamos las existencias.

Both are correct, but the version without nosotros is more natural unless you want emphasis or contrast.

For example:

• Nosotros revisamos las existencias, no ellos. = We checked the stock, not them.

Yes, absolutely.

Both are correct:

• En lugar de comprar otro lote, revisamos las existencias.
• Revisamos las existencias en lugar de comprar otro lote.

The version with en lugar de... at the beginning puts more focus on the contrast from the start. The second version starts with the main action.

Because the sentence begins with a fronted introductory phrase:

• En lugar de comprar otro lote, ...

In Spanish, it is very common to put a comma after this kind of introductory element, especially when it is a bit long.

If the phrase came later, there would usually be no comma:

• Revisamos las existencias en lugar de comprar otro lote.

Usually, yes. In Spain, existencias often sounds more standard or formal in business, logistics, accounting, or inventory management.

You may also hear:

• stock — very common in shops and business contexts
• inventario — inventory
• mercancía — merchandise/goods

But revisar las existencias is a very natural phrase in formal or semi-formal Spanish.

You could, but it changes the nuance.

• mirar = to look at
• revisar = to check/inspect/review

If the idea is that someone carefully checked inventory levels, revisar is better.

So:

• Miramos las existencias = we looked at the stock
• Revisamos las existencias = we checked/reviewed the stock

In a business context, revisar is more precise.

It works perfectly in Spain Spanish, and it is also understandable in most of the Spanish-speaking world.

Some vocabulary choices may vary by region:

• existencias is widely understood, but some places may prefer inventario or stock
• lote is also widely understood, though another term might be preferred depending on the industry

So the sentence is not exclusive to Spain, but it fits Spain Spanish very naturally.
