What if it takes longer than estimated?

Our problem, not yours. The point of fixed-fee is that you know the price before we start. Scope changes (you add something) are quoted as a separate add-on you approve before any work happens. Discovery quality is how we keep overruns rare — we don't quote until we're confident.

Can I add scope mid-sprint?

Yes — quoted as a discrete add-on, signed before work starts. We don't surprise-invoice.

What if the project doesn't ship?

Discovery is paid separately ($8–$20K, 1–2 weeks). If discovery surfaces a reason not to build, you walked away with that conclusion at 1/10th the cost. We've recommended 'don't build this' on 1 of every 8 engagements we've discovered.

Engagement model

Fixed-fee Sprint

One deliverable, one fixed price, one fixed timeline. The default.

When you know what you want shipped, a Fixed-fee Sprint is the cleanest path. We commit to scope and price after a 1–2 week discovery; you commit to the dependencies (access, sign-off owners, the data we need). Overruns are our problem, not yours.
