Email the recruiter follow-up questions or a counter offer. Negotiate your salary and write a job offer acceptance letter.The first step of the process is to write a reply letter (or email, if that's how your offer was sent) to ask for your desired salary. I received a tentative job offer with the salary listed at step 1. It can also make it easier for you to draft up an official acceptance letter in response. Salary negotiations are time sensitive. You've landed the job, but now you're wondering how to respond or write an acceptance letter. Here's a guide on how to accept a job offer. In my opinion, it's best to wait until you have received an official job offer before you negotiate salary. Approach the conversation with a positive attitude and a willingness to find a solution that works for both parties.
