Offer Letter vs Appointment Letter: the Difference, Explained (2026)

Offer letter vs appointment letter: the short answer An offer letter is the document an employer sends first, proposing the job: the role, the pay and the joining date. It is an offer the candidate can accept or decline, and it is often conditional on checks such as background verification. An appointment letter is issued on or around the day the person joins, and it sets out the full terms of employment: the detailed salary break-up, reporting line, probation, notice period, leave, confidentiality and company policies. It is the document people look back to when a question arises later about service conditions. Put simply: the offer letter proposes the job; the appointment letter records the complete terms once you accept and join. In India both are common, and some employers combine them into one document. This article is general guidance, not legal advice. Employment law and the rollout of labour-code rules vary, so take advice on a specific document or dispute. ## What is an offer letter? An offer letter is a short proposal. It usually states the designation, the salary or CTC the employer has in mind, the proposed joining date and location, and any conditions. Common conditions include successful background verification, reference checks, and submission of documents. Legally, an offer letter is an offer under the Indian Contract Act, 1872. Before the candidate accepts, the employer can withdraw it. Once the candidate accepts, a contract is formed, subject to any stated conditions. If the offer was conditional and a condition is not met, for example a background check fails, withdrawal can still be possible. If either side pulls out wrongly, the usual remedy is damages; a court will not force an employment relationship into existence. ## What is an appointment letter? An appointment letter is the fuller record, issued on or near the joining date. It typically covers: - the confirmed designation and reporting manager or department;

• the detailed salary structure and benefits;
• the probation period and confirmation process;
• the notice period for each side;
• leave entitlement and working hours;
• confidentiality, intellectual property and, where used, non-compete or non-solicit terms;
• a reference to the company's policies and code of conduct. Because it is the complete statement of terms, the appointment letter is usually the primary document people rely on if a later dispute arises about salary, notice or service conditions. ## Key differences at a glance | Feature | Offer letter | Appointment letter | |---|---|---| | When issued | First, during or after selection | On or around the joining date | | Purpose | Proposes the job and headline terms | Records the full terms of employment | | Detail | Brief: role, pay, start date, conditions | Detailed: salary break-up, probation, notice, policies | | Conditional | Often (checks, verification) | Usually unconditional once joined | | Binding effect | Becomes binding on acceptance, subject to conditions | Governs the ongoing employment relationship | | Main use later | Evidence of the original offer | The primary reference for service conditions | ## When each matters - The offer letter matters most at the hiring stage: it is what the candidate relies on to resign from a current job, so clarity about conditions and withdrawal rights protects both sides.
• The appointment letter matters throughout employment and at exit: it is the document that decides notice periods, probation, confidentiality and what happens on resignation or termination. Many employers combine both into a single document, which is acceptable. What matters is that the terms are clear and consistent. ## Common mistakes and variations - An offer letter that contradicts the later appointment letter, so it is unclear which governs. Many drafters add a line stating that the appointment letter supersedes the offer letter.
• An offer letter silent on key terms (notice, probation, confidentiality) with no appointment letter to follow, leaving the relationship on thin terms.
• Treating a conditional offer as unconditional, so an employer is surprised it cannot withdraw cleanly, or a candidate is surprised it can.
• Missing or vague joining conditions, which cause disputes when a background check throws up an issue. ## Does it vary by jurisdiction? Yes. This page is written India-first, and the detail differs elsewhere. - India. Both documents are contractual under the Indian Contract Act, 1872. Separately, India's new labour codes, including the Code on Occupational Safety, Health and Working Conditions, 2020, move towards requiring employers to issue appointment letters to employees.

• UK, Ireland, Singapore, Australia, United States. The documents and their names differ. Many of these markets require a written statement of particulars or a formal employment contract rather than the India-style offer-plus-appointment pair, and at-will employment in much of the US changes the picture entirely. Because both the documents and the statutory requirements differ, say "varies by jurisdiction" and check local employment law. ## One workspace for the whole employment document set, not just one letter Getting a single letter right is one task.
