1. Communication Tools: To keep the workflow smooth and transparent, platforms allow direct communication channels between brands and influencers. Regular reminders and notifications about milestones can be facilitated.

2. Performance Monitoring: Regular tracking of the influencers’ activities and comparing them with the pre-set campaign deadlines is vital. If there are aberrations, immediate steps can be taken.

3. Contract Enforcement: Enforcing penalties in the contract for delayed deliverables is a proactive approach to keep things on schedule.

4. Influencer Replacement: If an influencer consistently fails to meet their commitments, the platform often provides quick search and replacement options to minimize campaign interruptions.

5. Project Management Tools: Using the project management capabilities of the platform, one can set clear expectations, deadlines and can monitor the progress of the campaign more effectively.

6. Escalation Mechanism: An ideal platform normally provides escalation mechanisms to approach higher authorities in case of conflicts or non-compliance.
