How to Write a Job Offer Letter (Format + Free Template)

A job offer letter is the first formal document a company sends to a selected candidate. It confirms the role, salary, and terms in writing, setting a professional tone before the employee joins. A well-written offer letter prevents confusion later and protects both sides. Here is how to write one.

What Is a Job Offer Letter?

An offer letter is a formal communication from the employer to a candidate, stating that they are being offered a position and outlining the main terms of employment. It is usually issued after interviews are complete and the candidate has been selected, and it often precedes a detailed appointment letter or employment contract.

Essential Fields to Include

A clear offer letter in India typically contains the following:

Company letterhead with the company name and address
Date of the offer
Candidate's name and address
Job title and department
Job location and reporting manager, if known
Start date or expected date of joining
Compensation details, such as the annual CTC and a brief salary structure
Working hours and probation period, if applicable
Conditions of the offer, for example successful background or document verification
Validity of the offer and the date by which to respond
A space for acceptance, with the candidate's signature and date

A Simple Offer Letter Template

You can adapt the following template to your needs. Replace the bracketed text with actual details.

Heading: Company letterhead, followed by the date.
Salutation: Dear [Candidate Name],
Opening: We are pleased to offer you the position of [Job Title] at [Company Name].
Key terms: Your date of joining will be [Date], your work location will be [Location], and your annual CTC will be [Amount].
Conditions: This offer is subject to verification of your documents and references.
Response: Please confirm your acceptance by signing and returning this letter on or before [Date].
Closing: We look forward to welcoming you to the team. Sincerely, [Name], [Designation].

Tips for a Professional Offer Letter

Keep the language clear and courteous. Avoid jargon and ambiguous phrasing.
State the salary structure plainly so the candidate understands the take-home versus the CTC.
Mention conditions upfront, such as background checks, to avoid surprises.
Set a clear validity date so the offer does not stay open indefinitely.
Proofread carefully, as errors in name, title, or salary look unprofessional.

Offer Letter vs Appointment Letter

An offer letter and an appointment letter are related but different. The offer letter is issued first and summarises the main terms, asking the candidate to accept. The appointment letter is usually issued on or after joining and contains the full, detailed terms and conditions of employment. Many small companies combine the two, but keeping them separate gives the candidate a quick confirmation followed by complete documentation.

Common Mistakes to Avoid

Leaving out the date of joining or the salary, which are the details candidates care about most.
Forgetting to mention any probation period or notice period.
Not adding a signature or acceptance section, so there is no record of acceptance.
Promising benefits verbally that are not written in the letter.

What to Do After Sending the Offer

Issuing the letter is not the end of the process. A few follow-up steps keep things smooth:

Confirm receipt with the candidate, as emails can land in spam.
Be available for questions about salary structure, benefits, or the joining date.
Set a clear deadline for acceptance and follow up politely if you do not hear back.
Begin onboarding preparation once the signed acceptance arrives, such as document collection and workspace setup.

Treating the offer stage with care leaves a strong first impression and reduces the chance of a candidate dropping out before joining.

Legal and Practical Notes

An offer letter creates expectations, so accuracy matters. Make sure the salary, designation, and joining date exactly match what was discussed, because discrepancies can lead to disputes or a withdrawn acceptance. If the offer is conditional, for example on a background check or notice-period completion, state that clearly so there is no misunderstanding. For senior or specialised roles, many companies have the letter reviewed internally before it goes out. Keeping a signed copy on file protects the company and gives the new employee a clear record of the terms they agreed to.

Conclusion

A good job offer letter is clear, complete, and professional. It tells the candidate exactly what role they are being offered, on what terms, and by when to respond. Include the essential fields, keep the tone warm but precise, and follow up with a detailed appointment letter once the candidate joins. A few minutes spent getting the offer letter right sets the relationship off on the right foot.
