Frequently Asked Questions

Starter is for validating one idea: a single AI agent, one AI feature, or one core MVP workflow. Professional — the recommended tier in every category — is for launching a product you will charge for, with billing, an admin view and post-launch support. Enterprise adds SSO, audit logs, multi-agent orchestration, on-device AI or Kubernetes for teams selling to larger buyers. If you are unsure, book a call and I will tell you which one fits.

Yes. If requirements grow, we move to the next tier and you pay only the difference; the work already delivered carries over. Going from a Starter MVP to a Professional one with Stripe and an AI feature is the most common upgrade.

Wise, Payoneer, international bank transfer and Stripe invoicing for cards, all in USD. Fixed-price packages are split into milestones — typically 40% to start, 40% at the mid-point demo and 20% on handoff. Clients in Bangladesh can pay by local bank transfer in taka.

Your own accounts carry them: hosting is usually $20-100 a month early on, a managed Postgres is free to $25, and LLM API fees run from a few dollars for a small tool to $50-500 a month for a growing SaaS. Every AI package ships with cost caps and a usage dashboard, and the proposal includes a running-cost estimate.

Professional tiers include two weeks of post-launch support and Enterprise tiers 30-60 days. After that, a monthly retainer from $500 covers maintenance and new features, or you can book hourly work at $100-150 when you need it.

You receive all source code in your own GitHub organisation, documentation, and the credentials for every service, with full IP assignment on final payment. I walk you through the handoff on a call and stay available during the support period.

Tell me what you need through the contact page or on a call. Longer engagements, existing codebases and unusual scopes are quoted as a custom fixed price, an hourly engagement at $100-150, or a retainer.
