Day 14: Write an Offer Letter

The concept

An offer letter is both a formal document and an emotional moment.

The candidate has invested time, energy, and trust in the hiring process. They may be comparing offers, preparing to resign, discussing the move with family, or deciding whether this organisation feels like the right next step. The offer letter may be the first formal document they receive from you. It should be accurate, but it should not feel cold.

AI can help draft a clearer and warmer offer letter, but HR must protect accuracy. Offer terms matter. A warm mistake is still a mistake.

Plain English

The offer letter should make the candidate feel welcomed while clearly setting out the terms they are being asked to accept.

Lead with the welcome

Many offer letters begin with stiff legal language. That is a missed opportunity.

A stronger opening acknowledges the candidate and the decision:

We were impressed by your experience throughout the process, and we are delighted to offer you the role.

This does not weaken the document. It sets a human tone before the formal terms.

The candidate should feel that the organisation is pleased they are joining, not merely processing a transaction.

Keep terms clear

The letter should clearly state:

• job title
• department
• manager or reporting line
• employment type
• start date
• location or working pattern
• salary
• bonus or variable pay
• benefits summary
• probation period
• notice period
• conditions
• response deadline

Plain English matters. Candidates should not have to interpret complex wording to understand what they are accepting.

Align with the contract

An offer letter should not conflict with the employment contract, handbook, or written statement of terms.

Check:

• salary amount
• currency
• pay frequency
• job title
• start date
• employment type
• probation terms
• notice period
• bonus wording
• benefits eligibility
• location or hybrid terms
• conditions of offer
• right-to-work requirements

If anything is non-standard, review it carefully before sending.

Be careful with variable pay

Bonus, commission, equity, and incentive plans often create confusion.

If variable pay is discretionary, say so. If eligibility depends on start date, performance, company results, or plan rules, the letter should not overpromise. If equity is involved, make sure grant terms, vesting, and approvals are handled through the correct legal documents.

AI can draft the wording, but HR and legal must ensure it matches the actual plan.

Explain conditions clearly

Conditional offers should be easy to understand.

Common conditions include:

• references
• right-to-work verification
• background checks
• qualifications
• professional registration
• medical or occupational health clearance where appropriate

The candidate should know what is required, by when, and who will contact them.

Do not make the conditions sound threatening. They are a normal part of the process. Clear explanation reduces anxiety.

Add a personal note

The formal letter does not need to carry the entire emotional weight of the offer.

A short note from the hiring manager can make the experience feel more personal:

• thank the candidate for their time
• mention genuine excitement
• acknowledge something specific from the process
• explain that the formal letter is attached
• invite questions

This note should be brief and sincere. It should not introduce new terms or promises.

Consider the pre-offer call

For important roles, the hiring manager or recruiter should usually speak with the candidate before or alongside the formal letter.

The call can:

• express enthusiasm
• confirm key terms
• answer immediate questions
• explain next steps
• understand timing
• reduce surprises

AI can help create a call script, but the conversation should sound natural. The goal is connection and clarity.

Manage candidate questions carefully

Candidates may ask about flexibility, bonus likelihood, career path, benefits details, equipment, relocation, notice period, or negotiation.

Prepare answers before the offer is sent. If a question needs legal, payroll, or leadership input, do not improvise. A confident but inaccurate answer can create problems later.

Useful preparation includes:

• what is negotiable
• what is fixed
• who can approve changes
• how long the offer remains open
• what checks are still pending
• who handles benefits questions
• what happens after acceptance

AI can draft a candidate FAQ, but HR should validate every answer against policy and contract terms.

Keep warmth separate from promises

A good offer experience is warm, but it should not create promises the organisation cannot keep.

Avoid language such as:

• guaranteed rapid promotion
• guaranteed bonus payout
• permanent remote work if policy may change
• indefinite role stability
• benefits not yet approved
• start-date promises before checks are complete

You can be enthusiastic without overcommitting.

For example:

We are excited about the experience you will bring to the team and look forward to supporting your first few months with us.

That is warm and safe. It does not create a specific promise outside the offer terms.

Make acceptance easy

The offer letter should make the next step obvious.

Candidates should know:

• how to accept
• who to contact with questions
• the response deadline
• what checks happen next
• what documents they need to provide
• when they will hear from onboarding or HR operations

This is a small detail with a large effect. A candidate who has to ask how to accept, or what happens after they accept, experiences avoidable friction at exactly the moment the organisation should feel organised.

You can also ask AI to produce a short "what happens next" checklist. Keep it separate from the formal terms if needed, but make sure the candidate has it.

Review the candidate experience after acceptance

The offer letter is the start of onboarding, not the end of recruitment.

After the candidate accepts, HR should check:

• has the manager sent a personal welcome?
• has the contract been issued?
• are pre-employment checks underway?
• is the start date confirmed?
• has onboarding ownership been assigned?
• does the candidate know who to contact before day one?

A warm offer followed by silence weakens the experience. The handoff into onboarding should feel deliberate.

Today's practice

Use one offer scenario. Run the prompt. Then compare the output against the actual terms and your contract template.

Ask:

1. Is every term accurate?
2. Does the letter conflict with the contract?
3. Is variable pay described carefully?
4. Does the opening feel genuinely welcoming?
5. What should the hiring manager say personally?

By the end, you should have an offer letter that supports both compliance and candidate experience.
