- The grant letter is a binding contract. It applies the scheme’s rules to one named employee, so it must be consistent with the scheme and never contradict it.
- Nine clauses are non-negotiable: options granted, exercise price, grant date, vesting schedule, cliff, exercise window, termination treatment, lapse and forfeiture, and a reference to the scheme and the board approval.
- Most errors are copy-paste errors. A wrong strike price, a missing exercise window or a vesting table that does not match the scheme are the classic findings.
- A grant letter needs a paper trail: the approved scheme, the board or committee approval for the specific grant, the signed letter, and an entry in the options register.
- Templates beat hand-editing. ESOP Flow generates grant documents from a standard template and records each grant against the pool and register, for free.

What an ESOP Grant Letter Is
An ESOP grant letter, sometimes called a grant or award letter, is the document a company issues to formally award stock options to a specific employee under an approved ESOP scheme. It is easy to confuse with the scheme itself, but they do different jobs. The scheme is the master rulebook approved by the board and shareholders: eligibility, the size of the pool, the vesting methods allowed, exercise mechanics and exit terms for the whole plan. The grant letter takes those rules and applies them to one named person: this employee, these many options, at this price, vesting on this schedule.
That distinction matters because the grant letter is the instrument the employee actually holds. Once it is issued under a valid scheme and the employee accepts it, it is a binding contract that entitles them to the options on the stated terms. It is the first document an employee reads to understand what they own, and one of the first a diligence team pulls to check that your grants are real, consistent and properly approved. For the employee’s own view of what happens next, we link the ESOP lifecycle guide, but this post stays firmly on the drafting side.
The Anatomy of a Grant Letter
A well-drafted grant letter is not long, but every clause is load-bearing. Here is what each part does and why it cannot be skipped.
- Number of options granted to this employee
- Exercise / strike price per option
- Grant date, the anchor for everything
- Class of Equity Shares the options convert into
- Vesting schedule (for example 4 years)
- Cliff (typically 1 year)
- Exercise window and the last date to exercise
- Vesting basis: time, milestone or hybrid
- Termination treatment (good vs bad leaver)
- Lapse and forfeiture rules
- Post-termination exercise period
- Reference to the scheme & board approval
Two clauses cause the most confusion in practice. The exercise price (or strike price) is what the employee pays per share to convert a vested option into an actual Equity Share; it is fixed at grant and, on exercise, the gap between the fair market value on that date and this price becomes the taxable perquisite. The exercise window is the period, both during employment and, crucially, after leaving, within which vested options can be exercised before they lapse. Founders remember to state the vesting schedule and forget the window, and a missing window is one of the more common drafting gaps. For how the schedule itself is designed, see designing the vesting schedule.
The Must-Include Checklist
Before any grant letter goes out, run it against this list. Every item should be present, unambiguous and consistent with the scheme.
Common Drafting Mistakes
Almost every grant-letter problem is a consistency problem, not a legal-theory problem. These are the ones that show up again and again in diligence.
- The letter contradicts the scheme. A vesting table or exercise window in the letter that does not match the master scheme creates ambiguity in a binding instrument.
- A wrong or missing exercise price. A copy-paste error on the strike price mis-states both what the employee pays and their tax base.
- No exercise window, especially post-termination. Founders state the vesting but forget when, and for how long after leaving, options can actually be exercised.
- No reference to the board approval. A grant with no approval cited behind it looks unauthorised, whatever the intent.
- Undated or unaccepted. A grant date drives all the vesting math; a letter the employee never signed is not a two-sided record.
- The letter and the register disagree. The option count in the letter does not match what is recorded against the pool, so the numbers do not reconcile.
Draft the template once, have it reviewed against the scheme once, and then issue it consistently for every grant. The expensive version is a folder of hand-edited Word letters that each drifted a little from the scheme, discovered by a diligence team one round later. Consistency is cheaper than cleanup.
The Paper Trail Behind Every Grant
A grant letter does not stand alone. It sits at the end of an approval chain, and it feeds into a register. Under Section 62(1)(b) of the Companies Act 2013 and Rule 12, the ESOP scheme is approved by a board resolution and a shareholders’ resolution (special or ordinary as applicable). Individual grants are then made under a board or committee approval, the letter is issued and accepted, and the grant is entered in the company’s options register. Miss a link and the grant looks unauthorised, however genuine it was.
The register is where it all reconciles. Every grant letter you issue should show up as a row against the pool, with the option count, exercise price, grant date and vesting status tying back exactly to the letter. When the letter and the register are driven off the same source of truth, they cannot drift; when they are maintained separately in Word and a spreadsheet, they always do. For what happens when the employee later converts options to shares, see exercise and TDS.
Automating Grant Documents
The single best defence against grant-letter errors is to stop hand-editing them. Instead of copying a Word template and typing new numbers into it for every hire, an ESOP administration tool generates each letter from a standard, scheme-consistent template, populated automatically with the employee’s name, option count, exercise price, grant date and vesting schedule, and records the grant against the pool and the register at the same moment. The copy-paste errors disappear because there is no copy-paste, and the letter, the register and the vesting engine all read from one source.
“A grant letter is a promise you are putting in writing and a compliance record at the same time. Generate it from one template tied to your register, and you never have the version where the letter says one thing and the pool says another.”
Ankit Sarawagi, CFOmatrixThat is exactly what ESOP Flow does. It holds your scheme and document templates, auto-generates grant documents from them, records each grant against the option pool with the automated vesting engine, and keeps the ESOP register in step, all free. You draft the template once; the tool issues every consistent, reconciled grant after that.
Frequently Asked Questions
What is an ESOP grant letter?
An ESOP grant letter, also called a grant or award letter, is the document a company issues to formally award stock options to an individual employee under an approved ESOP scheme. The scheme sets the general rules for the whole plan; the grant letter applies those rules to one person, recording exactly how many options they are being granted, the exercise price, the grant date, the vesting schedule and cliff, the exercise window and what happens if they leave. It is the personal contract that sits under the scheme, and once accepted it becomes the primary evidence of that employee’s entitlement.
What must an ESOP grant letter include?
A complete grant letter should state the number of options granted, the exercise or strike price per option, the grant date, the full vesting schedule with the cliff, the exercise window and the last date to exercise, the treatment of options on termination (good leaver and bad leaver), lapse and forfeiture rules, and a clear reference to the governing ESOP scheme and the board approval under which the grant is made. It should also name the employee, be dated and signed, and require the employee to accept in writing so there is a two-sided record.
What is the exercise price in an ESOP grant letter?
The exercise price, also called the strike price, is the amount an employee must pay per share to convert a vested option into an actual Equity Share. It is fixed at grant and stated in the grant letter, often at a discount to the last preferred round or the fair value, subject to the scheme. On exercise, the difference between the fair market value on that date and the exercise price is the taxable perquisite in the employee’s hands. Because it sets both what the employee pays and the tax base, the exercise price must be stated precisely and must match the board approval.
Is an ESOP grant letter legally binding?
Yes. Once issued under a validly approved scheme and accepted by the employee, the grant letter is a binding contract that entitles the employee to the options on the stated terms. That is why it must be internally consistent, must reference the board and shareholder approval and the scheme, and must not contradict the scheme document. If the letter and the scheme conflict, you have created ambiguity in a binding instrument, which is exactly what surfaces, expensively, in a later diligence or dispute. Have the template reviewed once, then issue consistently.
Do I need board approval before issuing a grant letter?
Yes. The ESOP scheme itself is approved by a board resolution and a shareholders’ resolution (special or ordinary as applicable) under Section 62(1)(b) of the Companies Act 2013 and Rule 12. Individual grants are then made under a board or committee approval that authorises the specific options for named employees. The grant letter should reference that approval, and the grant should be entered in the company’s options register. Issuing a grant letter without a proper approval and paper trail behind it undermines the grant and is a common diligence finding.
Can I automate ESOP grant letters?
Yes. Instead of copy-pasting a Word template and editing numbers by hand, an ESOP administration tool generates each grant letter from a standard, scheme-consistent template, populated with the employee’s name, option count, exercise price, grant date and vesting schedule, and records the grant against the option pool and the register at the same time. This removes the copy-paste errors that make letters contradict the scheme, and keeps the letter, the register and the vesting engine in step. ESOP Flow generates grant documents from templates and manages grants for free.
