The work
Client names stay private. The industries, the problems, and the systems are real.

- Claims builtvalidated per payer before anything leaves
- Submittedthe payer acknowledgment is the evidence
- Trackedevery status visible to every biller
- Reconciledan export that matches the books
- One queueinstead of three tools and a spreadsheet

- A fixed price with milestonesA written scope. You know the number before we start.
- Working software every weekYou see it running as it’s built, not at the end.
- Handoff — you own itCode, hosting, data. A review window. No lock-in.
