Key takeaways
- The offer letter comes first, is short, and is written to be accepted or declined.
- The contract comes second, is detailed, and is the document relied on for the whole employment relationship.
- An accepted offer letter can create binding obligations — write it as if it will be enforced.
- Job title, start date, salary breakdown and reporting line must be identical in both.
Side by side
| Aspect | Offer letter | Employment contract |
|---|---|---|
| Purpose | Propose the role and headline terms | Govern the working relationship in full |
| Length | One to two pages | Several pages of clauses |
| Timing | Issued before acceptance | Signed on or before the start date |
| Detail level | Title, salary, start date, main benefits, conditions | Duties, hours, leave, probation, notice, confidentiality, IP, governing law |
| Conditionality | Usually conditional on references, visa, medical | Unconditional once signed |
| Binding effect | Binding on the terms it states once accepted | The controlling document for the relationship |
| Used later for | Evidence of what was promised | Salary certificates, NOCs, disputes, end-of-service calculations |
Is an offer letter binding?
Often, at least in part. Once a candidate accepts in writing, the letter evidences an agreement on the terms it states — title, salary, start date. That is why a well-drafted offer letter says explicitly what it is conditional on and states that full terms will be set out in the employment contract to be signed before the start date.
- List the conditions plainly: satisfactory references, background check, medical, visa or work permit approval.
- Give the offer an expiry date so it does not stay open indefinitely.
- Say that the employment contract will contain the complete terms.
- Avoid promising anything you have not yet decided how to deliver, such as an unspecified bonus.
Where the two documents drift apart
The most common failure is not a legal one but a clerical one: the offer quotes a single gross salary, the contract splits it into basic pay plus allowances, and the two do not reconcile. Because gratuity and leave pay in the GCC are usually calculated on basic salary, a candidate who accepted a total figure can find the underlying basic is much lower than expected.
- Decide the salary breakdown before the offer goes out, and show it in the offer.
- Keep job title identical, character for character, in both documents.
- Keep the start date identical; if it moves, reissue the offer or amend it in writing.
- Carry every benefit named in the offer into a clause in the contract.
- Have one person cross-check both documents before either is sent.
If a term genuinely has to change between offer and contract, say so explicitly and get written acceptance of the change. A silent change discovered on signing day is what turns a hire into a dispute.
A practical issuing sequence
- Verbal offer and confirmation of expectations, including notice period at the current employer.
- Written offer letter with conditions and expiry date.
- Written acceptance from the candidate.
- Conditions cleared: references, medical, permit steps as applicable.
- Employment contract prepared, matching the offer, and signed by both parties.
- Registration or filing where required, then onboarding documents.
Frequently asked questions
Can I hire someone on an offer letter alone?
Not safely. The offer letter does not cover duties, hours, leave, confidentiality or termination, and in most GCC jurisdictions a registered written contract is part of the work permit process. Treat the offer as step one, not the whole file.
Can an employer withdraw an offer letter?
Before acceptance, generally yes. After acceptance, withdrawal can expose the employer to a claim, especially where the candidate resigned from another role in reliance on it. Conditions stated in the letter are the legitimate route to withdraw.
Which document wins if they contradict each other?
Normally the signed employment contract, particularly where it states that it supersedes prior communications. That is precisely why the offer should not promise anything the contract will not repeat.
Should the offer letter show the salary breakdown?
Yes. Showing basic salary and each allowance in the offer prevents the most common dispute, because end-of-service and leave calculations depend on the basic figure rather than the total package.
Does the candidate sign the offer letter?
Have them sign and return a copy, or accept clearly by email. Written acceptance fixes the date and the terms accepted, which matters if the start date or salary is later questioned.
What if the start date slips?
Amend it in writing before the original date passes, referencing the offer or contract by date. An unamended date makes attendance records, probation end dates and gratuity accrual harder to defend.
