An offer letter is a starting position, not a take-it-or-leave-it document. Companies extend offers expecting some negotiation. The candidates who don't negotiate leave money, equity, and better terms on the table — not because the terms weren't available, but because they didn't ask.
What can you actually negotiate in an offer letter?
More than most people realize. The obvious items: base salary, signing bonus, equity grant size, start date. The less obvious but equally important: equity vesting cliff length (ask for 6 months instead of 12), equity acceleration terms on acquisition, non-compete duration and scope, invention assignment carve-out for prior work and side projects, signing bonus clawback terms (does it apply if you're laid off?), PTO policy, remote work flexibility, and title. All of these are negotiable at most companies, especially in a competitive hiring market.
How to negotiate salary in an offer letter
The standard approach: counter with a specific number, not a range. 'I was hoping for $135,000' is stronger than 'I was thinking somewhere between $130k and $140k' because ranges always anchor to the lower number. Cite the market — 'Based on similar roles at comparable companies, I was expecting $135,000.' If they can't move on salary, ask what else is flexible — signing bonus, equity, remote work, earlier review cycle. Most hiring managers have more flexibility on non-salary items.
How to negotiate non-compete language
Non-compete negotiation is more accepted than most candidates realize, especially for roles that don't involve genuinely sensitive competitive information. Ask for: shorter duration (6 months instead of 2 years), narrower geographic scope if specified, industry scope limited to your direct competitors rather than the whole sector, or removal if you can make the case that the role doesn't warrant it. Frame it professionally: 'I'd like to discuss the non-compete scope — I'm happy to protect legitimate business interests, and I want to make sure the language is reasonable for my situation.'
How to negotiate invention assignment language
This is one of the most important and most overlooked negotiation points. Ask for a prior inventions schedule — a list of your existing projects and tools that are excluded from the invention assignment. Most companies will accept this: they want the work you do for them, not your side projects. The ask: 'I'd like to attach a Schedule A listing my prior inventions and personal projects so we have clarity on what's excluded from the assignment clause.' If they refuse to add any carve-out, that's worth taking seriously.
When is the best time to negotiate?
After you have the offer in hand, before you sign. Once you've expressed genuine interest in the role ('I'm excited about this opportunity'), you have leverage. The company has invested significant time in interviewing and selecting you — they want to close. The worst time to negotiate is before you have an offer (premature), or after you've already signed (too late). Give yourself 1–3 days to review the offer thoroughly before responding.
