Can help be used in formal writing?
Yes. Help is acceptable in all registers. In professional reports and academic writing, both help and assist appear. Assist may sound more authoritative in very formal contexts.
Does assist always imply a secondary role?
Usually, yes. The word assist carries the implication of a supporting rather than leading role. “She assisted the manager” suggests she supported, not led. Help does not carry this hierarchical implication.

Helpful: “The staff were very helpful.” The adjective from assist is less common but assistive appears in medical/technical contexts: “assistive technology” (technology that helps people with disabilities).
Can I use “help” in customer service contexts?
Yes. “How can I help you?” is perfectly natural and warm in customer service. “How can I assist you?” is also used and sounds slightly more formal or professional.
Is there a difference between “help with” and “assist with”?
Both patterns take the same preposition with before the task: “help with the project” / “assist with the project.” The difference is only in formality; assist with sounds more professional.
Which is better in IELTS writing?
Both are appropriate. Using assist in formal academic essays can show a wider range of vocabulary. However, help is never wrong. Avoid overusing assist in casual contexts just to sound formal.
