Grammar Check

It's darn close if it isn't. The "but will" and "$$ extra" didn't seem proper to me.

That said, I would write it differently.

You can download it from the site. It's a full version that will expire after some [I'd provide the number of days or trials or whatever] time. If needed, we can also customize the product at an additional cost.

The last sentence can be written as....

1) If needed, we can also customize the product at a nominal cost.

2) If needed, we can also customize the product at an additional nominal cost.

Nominal as used in the sentences above means minor or insignificant. "Nominal" tends to be used in business a lot when the costs are not large. So if your customization "costs" are significant, don't use "nominal." Only use "nominal" if the customization work is a slight extra fee.

Aastha,

My pleasure. Just looking over my answer, I might change the "at" to "for."

Original - If needed, we can also customize the product at an additional cost.

Revised - If needed, we can also customize the product for an additional cost.

Original 1) - If needed, we can also customize the product at a nominal cost.

Revised 1) - If needed, we can also customize the product for a nominal cost.

Original 2) If needed, we can also customize the product at an additional nominal cost.

Revised 2) If needed, we can also customize the product for an additional nominal cost.

Now, you're probably wondering which is the correct form. Both are popularly used, but the "for" is more popularly used.

For example, googling...

with quotes

"at a nominal cost" - 22 thousand hits
"for a nominal cost" - 1.3 million hits

I have heard both forms used often, but I think the "for" form is more common.

I hope this additional information is helpful.

Data,

It's an interesting question. I saw two usage notes.

From GuruNet.com...

Let's go through them.

USAGE NOTE The word data is the plural of Latin datum, “something given,” but it is not always treated as a plural noun in English. The plural usage is still common, as this headline from the New York Times attests: “Data Are Elusive on the Homeless.” Sometimes scientists think of data as plural, as in These data do not support the conclusions. But more often scientists and researchers think of data as a singular mass entity like information, and most people now follow this in general usage. Sixty percent of the Usage Panel accepts the use of data with a singular verb and pronoun in the sentence Once the data is in, we can begin to analyze it. A still larger number, 77 percent, accepts the sentence We have very little data on the efficacy of such programs, where the quantifier very little, which is not used with similar plural nouns such as facts and results, implies that data here is indeed singular.

From the above note, it appears that singular is fine.

From Merriam-Webster Online dictionary...

usage Data leads a life of its own quite independent of datum, of which it was originally the plural. It occurs in two constructions: as a plural noun (like earnings), taking a plural verb and plural modifiers (as these, many, a few) but not cardinal numbers, and serving as a referent for plural pronouns (as they, them); and as an abstract mass noun (like information), taking a singular verb and singular modifiers (as this, much, little), and being referred to by a singular pronoun (it). Both constructions are standard. The plural construction is more common in print, evidently because the house style of several publishers mandates it.

I can't figure out what M-W is saying. Can you? I think you can choose your own rule with M-W and point to the appropriate sentences in M-W's explanation for support.

Me, I often use data as a singular noun.

Hope this helps.
