When you come across this situation where an influencer asks for a fee higher than your budget, it’s important to remember a few key points:

1. Negotiation: Like any business relationship, negotiation can always play a part. While influencers often have their pricing, there’s always room for a bit of back-and-forth. Keep in mind their reach and possible return on investment.

2. Consider Value Over Cost: Look beyond just the cost, consider the quality and reputation of the influencer. They might command a higher price, but can potentially bring superior results and a wider audience reach.

3. Alternative Compensation: Besides monetary compensation, consider offering other forms of rewards like free products, discounts, or exclusive access.

4. Collaborative Projects: Propose a collaboration on a project of mutual interest which can add value to both your brand and the influencer.

5. Plan B: Always have a backup plan in case terms cannot be agreed upon. This might be working with a different influencer, or reallocating budget elsewhere in your marketing plan.

In terms of identifying and reviewing influencers based on their demands and potential ROI for your brand, Flinque might be a helpful tool. It offers detailed influencer metrics to inform strategic decision-making, and possibly decide whether a higher fee may truly be justified.

Remember, balancing the influencer’s request with your marketing budget can sometimes be a challenging task, but it’s not impossible with careful planning and strategic thinking.
