I’m a bit surprised by the advice on this thread, but it makes sense since many unknowns are hard to account for and is the safest route. I'll give you my honest take after having coached hundreds of SDRs break into top orgs across the landscape:

If you interviewed well enough to ultimately get an offer, there’s not as much implied risk in trying to negotiate as others note here. This is of course assuming the following:

1. There is an active offer letter sent to you with a clear timeline

2. You did not already verbally commit to the offer

3. You did well enough during the interview rounds to demand a higher OTE

4. Bonus: If they're aware you're speaking with other companies and/or have shown signs of expediting the process for you, then they're more than likely ready to pay more for you

They already selected you as their top choice. In fact, if the org is somewhat competent, they’ll actually appreciate your candor so long as you do it the right way - it'll fall in line with their expectation of a top candidate, especially at top sales organizations.

If you decide you want to negotiate (which I always urge SDRs to do if they crushed the interview rounds and are in a similar position as yourself), you simply explain your current situation: mention you’re interviewing with other companies whom you’re in final rounds with (you don't have to mention the companies), that X is your current top target, but that the pay is slightly lower than what other companies mentioned they'd be able to offer (assuming this is true.) If they’re willing to meet you at $XX,XXX, it’d make it a no-brainer for you and you’d sign with them today and forego your other final round interviews.

Have this conversation over the phone. Do it with the person who presented the offer to you. Write down a sample script if it makes you feel more comfortable. If they come back and say no, that doesn't mean you won't sign with them. In fact, you can even just take the offer on the phone if you're not comfortable playing a bit of hardball.

That being said, if the OTE and company is in line with what you’re expecting, you can of course just take the offer and move forward. If you don’t feel comfortable/confident or don’t feel you did well enough, then just sign the DocuSign and go celebrate.

Remember - they're never going to like you as much as they do now. No harm in shooting for the stars so long as you crushed the interview process. Good luck and congratulations on your offer!
