Inspiration
In project-based work, completing a task and proving that it meets the agreed requirements are two different things. Clients often have to manually review files, check individual requirements, and communicate with service providers before deciding whether to release payment.
We wanted to make this process simpler and more transparent. This led us to build ProofPay, a platform that brings AI-powered work verification and PayPal payments together in one place.
What it does
ProofPay helps clients verify submitted work before making a payment.
A client creates a project, describes the expected outcome, and specifies the requirements. Once the service provider submits the deliverables, the AI system reviews them against the original project requirements.
The system produces a structured report highlighting completed requirements, missing items, and areas that need further attention.
Based on this report, the client can accept the work or request revisions. Once the client approves the submission, they can proceed with payment through PayPal.
The goal is to make the process more reliable while keeping the final approval decision in the hands of the client.
How we built it
We designed ProofPay around three main components: project management, AI-based verification, and payment processing.
The project management component handles project creation, requirements, and deliverable submissions.
The AI component processes the project requirements and submitted work, compares the two, and generates a structured verification report.
PayPal integration connects the approval workflow with payment processing, allowing users to proceed with transactions through the PayPal platform.
We focused on keeping these components connected so that users can manage a project, review its progress, and complete the payment process without switching between separate tools.
Challenges we ran into
One of the main challenges was figuring out how to evaluate work that can vary significantly from one project to another. A document, a website, and a design file cannot all be assessed in exactly the same way.
We addressed this by making project requirements the basis of the verification process, allowing the AI to evaluate submissions against the criteria provided by the client.
Another important consideration was the role of AI in financial decisions. We did not want an automated system to make payment decisions without the customer's involvement. Keeping human approval in the workflow was therefore an important design decision.
Connecting the verification process with payment processing also required us to consider transaction status, payment confirmation, and error handling.
Accomplishments that we're proud of
We are proud of the idea of connecting two processes that are usually handled separately: verifying completed work and making payments.
ProofPay is designed to give clients a clearer understanding of what they are paying for, while giving service providers a more transparent way to demonstrate that they have fulfilled the agreed requirements.
We are particularly proud of the human approval approach, which allows AI to assist with evaluation without taking control away from the people involved.
What we learned
Working on ProofPay helped us understand that building a useful AI application involves more than integrating a language model. The AI needs to solve a specific problem and fit naturally into the overall user experience.
We also gained a better understanding of how payment APIs can be integrated into application workflows and why payment confirmation, security, and user authorization are important.
Most importantly, we learned how AI and payment infrastructure can work together to address practical problems in everyday business transactions.
What's next for ProofPay – AI-Powered Work Verification & Payments
We see several opportunities to extend ProofPay beyond its initial use case.
Future improvements could include milestone-based payments, support for more document and media formats, advanced evidence verification, and dispute assistance.
We also want to explore how the platform could support different industries, including freelance services, software development, design, and other project-based businesses.
Our long-term goal is to make work verification a more natural part of the payment process.
