Tell us what's broken
A short note is enough. An engineer reads it and replies within one business day.
What we do
Modernization without the meltdown
Focused practices, one goal: keep your business running while we make its software faster, safer, and cheaper to maintain. The work ships in whatever the system already speaks — Python, TypeScript and JavaScript, Go, Rust, Java, C#, C++, SQL, and Swift among them, with COBOL and Fortran still read on the legacy end.
Workload Optimization
Squeeze more throughput out of the hardware and licenses you already pay for.
Workload Optimization →System Integration
Connect aging systems to modern APIs, data platforms, and SaaS tools.
System Integration →3PL & Logistics Systems
WMS, TMS, and warehouse-floor workflows for 3PLs, brokers, and distributors.
3PL & Logistics Systems →B2B EDI & Trading-Partner Integration
Onboard retail and customer partners over EDI or API — mapped, tested, and monitored.
B2B EDI & Trading-Partner Integration →Carrier Integration
Rate, tender, label, track, and audit across every carrier you ship with — parcel, LTL, and truckload.
Carrier Integration →3PL Reporting Layer
The reports your warehouse system won't build — on data landed in a database you own.
3PL Reporting Layer →Research & Feasibility Studies
Answer the question before you spend the budget — build vs. buy, feasibility, and due diligence.
Research & Feasibility Studies →Lean Six Sigma & Process Improvement
Fix the process before you automate it — measured with real data, not guessed.
Lean Six Sigma & Process Improvement →Custom Software & Web Development
Websites, internal tools, APIs, and automation for teams without a dev department.
Custom Software & Web Development →Starting a Business
Registered, online, and findable — the LLC, the domain, the email, the site, and Google.
Starting a Business →Veteran-Owned Businesses
Texas waives the formation fee and five years of franchise tax for veteran founders — we file the claim so it actually attaches.
Veteran-Owned Businesses →Power BI & Power Platform
Reports people trust, apps that fit the licence you already own, and flows somebody documented.
Power BI & Power Platform →AI & Automation
Practical AI for operations — documents read by software, checked by people.
AI & Automation →Customer Intake & Outreach
Every inquiry captured, routed, and followed up — instead of lost between an inbox and a notepad.
Customer Intake & Outreach →Data Entry & Analysis
Get the data in, get it clean, and get an answer out — without a week of copy-paste.
Data Entry & Analysis →Code Rescue & Support
Inherited an undocumented system nobody dares to touch? We make it safe to change.
Code Rescue & Support →Enterprise IT Services
Managed and co-managed IT across Texas — Active Directory to the printer that keeps dropping offline, and everything in between.
Enterprise IT Services →Fire Alarm Programming & Records
The software behind fire alarm work — documented, searchable, and out of one tech's laptop.

How we work
A low-risk path to legacy modernization
-
1
Assess
We map your systems, dependencies, and pain points — and tell you honestly what's worth changing.
-
2
Plan
A staged roadmap with measurable wins early, so value shows up before the big lift.
-
3
Modernize
Incremental delivery with automated tests and zero-downtime cutovers. No flag days.
-
4
Support
We stay on after launch to tune performance and keep the system healthy.
The same four steps on a two-week fix and on a two-year migration. Who you'd be working with, and why we work this way, is on the about page.
New practice
3PL & B2B logistics, wired together
Warehouses, brokers, and distributors run on a stack that rarely talks to itself. We connect the WMS, the TMS, the ERP, and every trading partner on the other end — so your team stops re-keying orders between screens. See the full 3PL & B2B logistics software practice.
3PL & warehouse systems
Scanner-driven receiving through shipping, multi-client inventory, billing that captures every accessorial, and portals your customers can log into.
3PL software →EDI & trading partners
X12, EDIFACT, and RosettaNet PIPs over AS2, SFTP, VAN, RNIF, or API — onboarded, routing-guide compliant, and monitored so failures reach you first.
EDI integration →Freight, carriers & visibility
Rate shopping, load tendering, tracking write-back, freight bill audit, and dashboards that show cost per order honestly.

Not just legacy
Custom software, Power BI & automation — same standard
Plenty of what we do is nothing like a mainframe: a spreadsheet that needs to become a real tool, a Power BI report nobody trusts, a process that should be fixed before it's automated at all.
Custom software, Web & apps
Web apps, websites, iOS and Android apps, and Windows tools for teams without a dev department — designed, not just assembled, and you own the code outright.
What we build →Starting a business
The LLC filed, the domain and business email set up, a website live on hosting you own, and your Google Business Profile claimed.
Get registered and online →Power BI & Power Platform
Reports that load fast and agree with each other, apps on the licences you already own, and flows somebody actually documented.
Power Platform →Research & feasibility
Build vs. buy, vendor selection, and feasibility answered with evidence — before the budget is committed.
Research & feasibility →Lean Six Sigma
Measure the process before you automate it. Automating a broken process just makes it break faster and cost more.
Process improvement →Customer intake & outreach
Every inquiry captured, routed, and followed up — plus outbound email that actually lands in the inbox.
Intake & outreach →Data entry & analysis
Backlogs digitized, duplicates gone, reports automated, and one definition per number everyone can agree on.
Data services →AI & automation
Software that reads the invoices, BOLs, POs, voicemails, and job-site photos your team retypes — with a person keeping the veto.
AI & automation →Enterprise IT services
Active Directory, endpoints, the network, servers and backups, Microsoft 365, help desk — and the printer that drops offline, fixed at the cause. Across Texas.

Our own software
Contactio finds the government contracts, grants and bids that fit your company
Give it your website and it builds the NAICS profile buyers search by, then reads six US contract and grant sources so the notices that match your work arrive sorted, with the deadline showing and the ones already closed left out. A free trial, no card to start it.
For veterans
Veterans: Texas waives your startup fees — we make sure you get them
A new business owned entirely by honorably discharged veterans pays no state formation fee and no franchise tax for its first five years — permanent Texas law since 2025, but only if it's claimed with the formation filing. We prepare the veteran paperwork, file the formation, and get the business online in accounts you own.
Confidentiality
What you tell us stays with us
Fixing your systems means seeing how your business really works. We don't trade on client names, we don't resell what we learn, and we won't put your logo on this website to win the next deal. The security practice behind that runs on the NIST Cybersecurity Framework (CSF) 2.0.
Your name stays private
We don't publish or share our client list, and your company appears in our marketing only if you tell us in writing that it can.
Your data stays yours
Records and documents you share are used to do your work — never sold, never reused as somebody else's sample data.
NDA before the details
We'll sign yours before the first technical call, so you can describe the real situation instead of a sanitized version of it.
