How it runs with AI
When the hiring manager records a selection in Darwinbox, the AI checks the agreed salary against the grade band, the role's budget and peers at the same grade and site. It drafts the letter and breakup from that entity's template and sends it to the right approvers on Teams, with the checks attached. Once they approve and the HR head signs, the candidate receives it on Leegality to sign.
How it is done today
Once a candidate is selected, a recruiter works out the salary breakup in an Excel calculator, copies it into the Word template for the right entity and site, and emails it to each approver. Pay against peers in the same grade gets checked only when an approver asks. A letter can take days and several rounds of email to reach the candidate.

What stays with a person
- The approvers approve the offer or send it back with changes, and the HR head e-signs it
What the pay check looks at
Every offer is checked against 3 references: the salary band for the grade, the budget approved for the role, and what people in the same grade at the same site earn today. When the salary is over budget or above the band, the AI adds the approver your policy names for that case, so the extra sign-off happens in the same round instead of a second one.
Apps in this example
Darwinbox
Microsoft Teams
- Leegality
The same flow works with the apps you use.
This fits you if
- You make more than 20 offers a month, across several sites or entities
- Recruiters build salary breakups in an Excel calculator today
- Offer approvals run over email and take several days
- Approvers ask how an offer compares with people already in the grade
What to watch for
- The salary, the approval and the signature stay with people. The AI drafts and checks, and sends the letter only after the HR head signs
- HR owns the grade bands, pay structures and letter templates, and updates them each appraisal cycle. The drafts follow whatever those say
- Salary data is confidential. Peer pay reaches the approvers as a range, and drafts sit in Darwinbox under HR's access rules
- The candidate's email says it comes from an automated assistant and names their recruiter for questions
