01

The intake

  • The intake call is free of charge. No fee is taken at booking and no payment details are collected.
  • A written scope is delivered within 72 hours of the call. It is yours to keep and to act on with or without us.
  • Booking an intake creates no obligation on either side. Any paid work begins only under a separately signed scope.
02

Fixed-price engagements

  • Productized engagements are quoted as a single fixed fee. That fee does not change during the engagement.
  • Fixed-price scope is what is written in the scope document. Additions require a written change order.
  • 50% is invoiced on signature. 50% is invoiced at go-live.
03

Custom engagements

  • Custom engagements are quoted as a range in the scope document and finalized at the end of a paid architecture phase.
  • Milestones are billed as reached. Nothing is invoiced without a demoable deliverable.
  • Timelines are estimates. Material delays are communicated in writing with an updated forecast.
04

The live-or-refund guarantee

  • If a productized system is not live in production within the timeline written in the scope document, you get 100% of the build fee back.
  • "Live in production" means the system is receiving real traffic on your infrastructure, not a demo environment.
  • Delays caused by you (e.g. missing credentials, delayed sign-off) pause the guarantee clock. Everything else does not.
05

Ownership

  • You own the code, credentials, workflows, and data delivered at engagement end. Transferred to your accounts on go-live.
  • Nexxorex retains the right to reference the engagement (anonymized where NDA applies) in case studies and marketing.
  • Open-source components remain under their original licenses.
06

Retainer + support

  • Post-launch retainer is optional and priced at engagement scoping.
  • Retainer includes 24/7 monitoring, monthly performance reviews, and one tuning round per month.
  • Bug fixes on originally-scoped features are covered under the 90-day post-launch warranty at no charge.
07

Liability

  • Nexxorex's aggregate liability for any engagement is capped at the fees paid under that engagement.
  • Nexxorex is not liable for third-party service outages (Retell, Twilio, Anthropic, etc.) beyond providing reasonable remediation.
  • Force majeure applies to both parties.
