05 Operating principles

How the prices hold.

Four rules apply to every engagement.

Fixed price, agreed first.

Every engagement has one price, written into the SOW before work starts. It does not move for the duration of the SOW.

Final payment after production acceptance.

The last payment is released only after the agreed acceptance criteria are met in production, not in staging. That removes the "demo works, production does not" failure mode.

Fixed scope, written change orders.

Scope is locked at the SOW. Material new scope is priced as a written change order with a price delta and timeline impact agreed before work resumes.

30 day stabilization on every build.

Bug fixes within the original scope are covered for 30 days after handoff at no extra cost. After that, support is a separate, optional retainer.

06 Common questions

On fixed prices.

Why fixed prices instead of hourly billing?

Fixed price puts the studio on the hook for delivery, not hours. Both sides know the number before work starts, and the final payment waits for production acceptance.

Are these prices negotiable?

The price is fixed for the agreed scope. More scope is a written change order with its own price. The studio does not run a "sign this week for 20% off" pattern.

How is a full build priced?

After a free 30 minute call, the studio writes a spec with milestones and acceptance criteria and quotes one fixed price. If the price does not work, nothing is owed.

Can a direct client buy the $1,500 white-label site?

No. White-label delivery is sold to agencies only, because the agency owns the client relationship, the brief and the account management. Direct clients use a build engagement.

What if our timeline is shorter than the delivery window?

The studio does not compress fixed-scope work below its honest delivery window. Rushed scope is the most common cause of post-handoff regret on the buyer side.
