What else can I ask for besides salary?

1. Signing Bonus
The first thing to negotiate is a sign-on or performance bonus. When salary negotiations hit a limit due to salary bands or other constraints, proposing a sign-on or performance-based bonus can add to your compensation. Ensure to clarify the specifics—get it in writing, be it a sign-on or yearly bonus.

2. Commission Percentage
You have the opportunity to discuss and potentially raise the commission percentage if you're in a sales position. Negotiating for a higher commission percentage allows you to increase your earnings from the sales you generate.
For example, in a sales role, your commission rate is tied to the sales you make. By negotiating a higher commission percentage, let's say from 5% to 7%, for instance, you can significantly boost your income for every sale you close."

3. Work From Home/Remote
Next, negotiate the work location. With the prevalence of remote work, discussing remote or hybrid work options is now easier. When receiving an offer, leverage this opportunity to negotiate for a percentage of remote work if it's crucial to you. This is your time for negotiation—seize it.

4. Expense Reimbursements
Negotiate expenses incurred for work-related activities, like phone bills, transportation, or additional work tools like tablets.

5. Training and Development
Early in your career, obtaining certifications, courses, or training is invaluable. Negotiate for this as part of your offer—be specific about the training or certification you're seeking and ensure it's documented in your offer.
By persuading your boss of its mutual benefits for both you and the company, obtaining funding for occasional continuing education shouldn't pose an issue.
