Offer letter: what it commits you to, and what it should not
An offer letter is the moment the terms become real. Conditions that are not in it cannot usually be added later, and promises made in it are hard to take back.
An employment contract exists whether or not anyone signs paper. Writing it properly is how you control what the unwritten version would have said.
An employment contract is the agreement between employer and employee setting out what the job is, what it pays, and the terms on which either side can end it. It comes into existence when an offer is accepted — in writing, verbally, or by the person simply turning up and working. What a written contract does is decide what those terms are, before a disagreement decides them for you.
Most jurisdictions also require certain particulars to be given to the employee in writing within a defined period, often by the first day. The specific list varies, and it is worth checking the requirement where the person actually works rather than where the company is registered — for remote hires those are increasingly different places.
The last line is the one that quietly causes trouble. Policies stated to be contractual cannot be changed without agreement; policies stated to be non-contractual can be updated as the business changes. Handbooks that do not say which they are get argued about at exactly the wrong moment.
Post-termination restrictions — non-compete, non-solicit — are enforceable only so far as they protect a legitimate interest and go no further than necessary, and several jurisdictions have narrowed or banned them for most roles. A twelve-month blanket non-compete pasted into every contract is usually unenforceable and occasionally unlawful.
Intellectual property assignment matters more than it looks in any company where employees write, design or code. So does the definition of confidential information: too narrow and it protects nothing, too wide and a court reads it down.
Changing terms later requires agreement, not announcement. Where a change is needed, the routes are consultation and consent, or in some jurisdictions dismissal and re-engagement — which carries its own risk. Contracts written on the assumption that terms can be varied unilaterally create the dispute they were meant to prevent.
The practical failure is rarely the drafting; it is that nobody can find the signed version, or that three variations exist and no one knows which is current. Ettex Signature records who signed, when, and what exact document, and keeps variations attached to the contract they amend — so the answer to "what are this person's terms" is one file rather than an archaeology exercise. Fitting the signature into the employee onboarding checklist is what stops it slipping past the first day.
Generally yes — a contract exists once an offer is accepted. The problem is proving its terms, which is why most jurisdictions require written particulars regardless.
It varies. Some jurisdictions require the principal statement by the first day of work, others within one or two months. Check the rule for the country and, where relevant, the state or province where the employee works.
Only by agreement, or through a process the contract itself permits. Imposing a change unilaterally risks a claim for breach or constructive dismissal.
Sometimes, and less often than employers assume. Enforceability depends on protecting a legitimate interest, reasonable scope and duration, and the law of the relevant jurisdiction — some now prohibit them for most employees.

A promissory note is a written promise to pay a fixed sum. Whether a court will enforce it comes down to a handful of terms most templates get wrong.
A covenant compliance certificate is a signed representation with arithmetic attached. The schedule showing how each ratio was derived is the part lenders read.
