Mobile App Development in Dallas, TX
DFW is a corporate IT and supply-chain heavyweight — Fortune 500 headquarters, a massive logistics base, and a deep pool of mid-market companies running internal mobile tools that were custom-built in 2014 on a now-deprecated platform. The Big Four wants to replace them with a $400,000 SaaS subscription. The freelance market is too thin to take on a forty-user internal mobile tool. We sit in the gap.
The problem with off-the-shelf mobile in Dallas
Mid-market DFW operators sit between a Big Four consulting bill that prices them out and a freelance market that cannot hold a forty-user internal mobile rollout. Custom mobile that ships on time, with documentation, against a fixed scope is what closes that gap.
A custom mobile build puts the data model, the UI, and the platform layer around how you actually operate. No vendor SDK tax. No per-seat ratchet. For Dallas operators specifically, that means mobile shaped for enterprise IT mobile replacing legacy — not a generic template.
What we ship for Dallas companies
Legacy internal-mobile modernization
Replace fragile Ionic 1, Cordova, or Xamarin builds with React Native + native modules — apps your team will actually use.
Logistics + freight driver apps
DFW's freight density is real — we model load, lane, customer, and broker into one mobile pipeline that consolidates legacy WMS feeds.
Procurement-ready documentation
Architecture diagrams, data-flow diagrams, SBOM-style summaries — what your IT leadership and audit team actually want to see.
Fixed-scope mobile modernization
Quoted up front, delivered against milestones. No T&M creep, no rolling change-order theater.
Tech stack
Hosted on Vercel, AWS, or your own infrastructure. PostgreSQL is the source of truth; the mobile client defers to it.
Reference builds
Production builds in our portfolio span operations platforms (J5 Sales OS, UEhub) and trade-side mobile patterns (Bridgepointe Painting for Stripe-to-QuickBooks invoice flow, Northcrest Fence for contractor lead routing). Same architecture pattern translates into a DFW mid-market modernization project: clean React Native code, role-scoped access, audit trails, and reporting on PostgreSQL views.
Reference work: J5 Sales OS, Northcrest Fence, and Bridgepointe Painting.
How we work remote from Georgia
QUANT LAB USA is founder-led from Macon, Georgia. William Beltz runs every engagement from kickoff through handoff — no agency middleman, no offshore handoff at the framework boundary. Discovery happens over a structured video session; weekly demos run on the same cadence; staging is live from week two so you can put a real mobile build in your team's hands before final delivery.
For Dallas clients, that means full Eastern-time overlap, fixed-scope contracting against milestones, and on-site work when the engagement warrants it. Book a scope call to walk through your workflow and get a written estimate.

Engagements include the mobile client, the backend, the API surface, Stripe and payments wiring as scoped, and App Store and Play Console submission. Source-code handoff is included at delivery — no platform fees, no per-seat charges, no vendor lock-in. See our parent mobile service page for the broader engagement model.

Dallas mobile FAQ
Can you modernize our existing internal mobile app instead of rebuilding?
Often yes — we do an assessment first. If the data model is sound and the UI is the problem, we rewrite the front and keep the schema. If both are broken, a clean rebuild is usually cheaper than another round of patches.
Do you bill fixed scope or T&M?
Fixed scope on most engagements. T&M only on open-ended R&D or live-incident response work where scope cannot be defined.
How do you handle a fifty-user internal rollout?
Phased — a usable v1 to one team in 8 weeks, then expansion. We train on real records during rollout and run a parallel period before sunset of the legacy app.
Will the app survive an enterprise procurement review?
Yes. We document architecture, ship audit trails by default, and produce the security artifacts (data flow, access model, encryption posture) procurement teams actually ask for.
Do you fly in for DFW kickoffs?
For engagements above a certain scope, yes. Otherwise full Central-time overlap from a Georgia HQ makes most reviews trivial to run remote.
Who owns the source code?
You do. Full repository handoff at delivery.
