Pricing FAQ

Questions about cost.

Are these prices all-in?

Yes. The listed price covers discovery, design, engineering, and production deployment. The only additional costs are third-party services you pay directly — hosting, payment processing, third-party APIs. We'll tell you what those will cost in week 1.

Can I pay in instalments?

For the MVP Sprint: 50% upfront, 50% on launch. For the Retainer: billed monthly. For the Audit: full payment upfront.

What if the MVP needs more scope than expected?

We shape aggressively in week 1 to make sure scope fits the 6 weeks. If your idea genuinely requires more than one sprint, we'll tell you before we start — not halfway through.

How does the 30-day fix guarantee work?

After launch, if any feature we committed to isn't working as agreed, we fix it at no charge within 30 days. This covers bugs and missing functionality — not new feature requests.
