Answers to common questions:
Still unsure about something? Here are answers to the most frequently asked questions about our process, pricing, and platform.
Working with us
We use a quota system in the BIYRO project management platform. For each milestone, you're given a number of quotas - which can be used for free changes within the project. This allows flexibility without additional costs. You can request changes right after a milestone is completed.
We recommend working through the BIYRO project management system, which generates contracts and adds an extra layer of security. The project is divided into milestones with agreed payment and delivery terms. Payment steps can be 20%, 50%, or 100% of the total budget. Your funds are held in BIYRO and released only after your approval. If we miss deadlines or fail to deliver, you can request a refund directly.
That's not a problem. We'll prepare the technical assignment for you based on your project concept before we begin development.
During the guarantee period, we fix any bugs or issues caused by our development - free of charge. We also offer extended guarantee coverage as a paid monthly service. Pricing is agreed individually per project.
BIYRO is our project management platform for secure development deals. It automatically creates contracts, stores payments safely, and releases funds only after your confirmation. You'll receive an email invitation to the platform once your project is ready to begin.
Yes - we deliver with clean structure and documentation. You’ll have full access, and we’ll guide you through any basic edits.
