Useme Plus - B2B calculator and membership product development

Business problem

The business needed a new revenue line through a membership product. This required a comparative calculator, electronic document workflow, admin panel, and validation automation - all while maintaining the stability of the existing platform.

Approach and solution

I co-developed a set of backend modules handling the full membership lifecycle: from the comparative calculator through document signing to automated validation and notifications.

Delivery scope

• Comparative cost calculator with tax logic for different Polish business forms.
• Autenti API integration - electronic document workflow with digital signatures for membership.
• Admin panel for membership management: statuses, renewals, cancellations.
• Auto-validator checking membership data correctness and sending custom emails to users, reducing customer service workload.

Business impact

• Launched Useme Plus as a new revenue line for the platform.
• Faster onboarding of new members through automation.
• Reduced customer service load via auto-validator with dedicated email templates.
• Electronic document workflow eliminating manual signature handling.
