Employee Offer Letter Guide: Making the Hire Official

You found the right candidate. They aced the interviews. Now it's time to make it official. An offer letter is more than a formality — it's the first piece of documentation that defines the employment relationship and sets expectations on both sides.

What Is an Offer Letter?

An offer letter is a formal written document from an employer to a prospective employee, outlining the terms of the job offer. Unlike a full employment contract, offer letters are typically shorter and less legally dense — but they still carry legal weight.

What to Include in an Offer Letter

Position and Start Date Clearly state the job title, whether the position is full-time or part-time, and the expected start date.

Compensation Specify the base salary or hourly rate. If There's a bonus structure, describe it here in general terms (detailed bonus agreements can go in a separate document).

Benefits Overview List the benefits package: health insurance, dental, vision, 401(k) matching, PTO policy. A general summary is fine; the details will be covered in the employee handbook or benefits documents.

At-Will Statement If your state is at-will, include clear language stating the employment is at-will and can be terminated by either party at any time. This is critical to avoid the offer letter being interpreted as a fixed-term contract.

Offer Expiration Date Set a deadline for the candidate to accept (typically 3–7 business days). This prevents candidates from using your offer as leverage while waiting for other offers indefinitely.

Conditions of Employment Include any conditions that must be met before employment begins: - Background check clearance - Drug test results - Verification of work authorization (I-9) - Receipt and signing of required policies (confidentiality, IP assignment)

What NOT to Include

• Guaranteed employment duration unless intentional ("you will be employed for one year" creates a binding commitment)
• Promises about future promotions or raises that may not materialize
• Discriminatory language of any kind
• Unrealistic probationary period promises ("if you pass your 90-day review, your job is guaranteed")

Common Offer Letter Mistakes

1. 1Forgetting the at-will statement — This single omission can make the letter read as a promise of ongoing employment
2. 2Sending before background check/drug screen — Legally safer to make the offer contingent on results
3. 3No expiration date — Candidates can sit on the offer indefinitely
4. 4No acknowledgment signature line — Always get the candidate's signature to confirm acceptance

Offer Letter vs. Employment Contract

An offer letter is a concise document that outlines key terms. A full employment contract goes deeper — covering non-compete restrictions, IP ownership, dispute resolution, and termination procedures. Many employers use an offer letter for initial hiring, then have employees sign a comprehensive employment contract on their first day.
