1. In English, we usually confirm points about or regarding a project. "Points of this" sounds a bit fragmented.
2. "At first" is used to describe a state that changed later (e.g., "At first I was tired, but then I felt better"). When listing items in a sequence, use First or Firstly.
3. "Achieve something" is too vague for a negotiation. Specifying "milestones" or "thresholds" sounds more professional.
4. "Discount" is usually a noun in this context. You need a verb like "get," "receive," or "apply" to make the sentence complete.
5. 7. We usually need an indefinite article ("a") before non-specific singular nouns like "discount", "contract."
6. When listing options or non-binding examples, "or" is more precise.

I’d like to clarify two details regarding the estimate. First, what is the deadline for this order? Additionally, do you offer any incentives for hitting specific targets? For instance, would you consider a volume discount or a reduced rate for a multi-year contract?

1. "Grateful" is a bit heavy/emotional for a business estimate. "Appreciate" is the standard professional choice.
2. "Provide" sounds more formal and natural than "give" in a corporate context.
3. This is a conditional statement (a "what if" scenario). Using "would be" is correct for hypothetical help.

Thanks for the quick answers. Regarding the estimate, please send over your suggestions. It'll help us speed up our internal review process.

1. The original is well-structured, but it could be clearer and more direct. For example:

Since the exact volume is subject to change, we propose extending the term.


+ Natural alternative:

Given that the final volume is difficult to predict, we suggest extending the contract term.

1. When "one year" or "two year" modifies a noun (like "contracts"), it needs a hyphen. It functions as a single adjective: one-year contracts.
2. While "products quality" isn't "wrong," it is much more standard in business English to use the singular "product quality" as a compound noun (similar to "water quality" or "service quality").
3. "Contract" is a singular countable noun. It requires an article like "a" before it (e.g., "a two-year contract").
4. I removed the "s" from "years" because when a measurement is used as an adjective before a noun, it stays singular (e.g., "a five-mile run" not "a five-miles run").


+ Natural alternative:

We usually do one-year terms, but we’re open to a two-year contract because we value our partnership and your product quality.

1. Adding a verb like "request" or "propose" makes the sentence feel more professional and less like a demand.
2. In "if" clauses referring to the future, we generally use the present simple tense rather than "will."
3. "Your products" is more concise. Using "company" twice in one sentence (our company... your company) sounds repetitive.
4. Using "a" is better here because a specific rate hasn't been agreed upon yet.


+ Natural alternative:

As our order volume is currently uncertain, could you provide a fixed annual rate? Should our volume increase in the future, we would be interested in discussing a tiered rate based on those higher quantities.
