Strangler pattern, not a rewrite
The legacy platform keeps running while each workflow moves behind a layer you own. No big-bang cutover, no six-month freeze.

How we think
Most companies do not need a rewrite. They need the old system to stop being the only place the truth lives. We put a modern layer in front of it and move one workflow at a time.

Why engineering leaders choose us
Senior engineering, without the hiring cycle.
A firm, not a single point of failure
Every engagement is led by a principal engineer and staffed with senior specialists for the scope: integration, frontend, data, QA. Documentation and handover are part of the build.
Weeks, not quarters
We scope the first deliverable to something that ships and proves itself quickly, then expand. Your team keeps its roadmap.
Security in the first commit
Least-privilege keys, server-side secrets, signed webhooks, role-gated routes and decision logs. Built to sit inside your SOC 2, HIPAA or GDPR program.
You own all of it
Code in your repository, infrastructure in your cloud accounts, full IP transfer on payment. Nothing is held hostage.
Failures are visible, never silent
Dead-letter queues, retries and plain-English status boards. When a vendor API misbehaves, you see it with evidence attached.
What we do
Engineering for
the systems you run.
Most engagements start with one integration or workflow, then expand once it has proven itself in production.

Home services and protection plans
Wrapping a legacy field-service platform in a modern integration layer
A multi-system operation ran billing, dispatch, inventory and CRM in four products that never talked to each other. We put one serverless integration layer in front of all of them instead of replacing any.
- 119
- Serverless functions in production
- 1,600+
- Automated tests on the integration layer
Property protection
From IoT leak sensor to automatic shut-off and a booked technician
Water sensors and smart valves in members' homes, wired to the dispatch system so a leak closes the valve, alerts the member and opens a work order, with interlocks so a valve never closes on the wrong home.

- Interlocks before any valve can close
- 1
- Event path from sensor to work order
Subscription services
Making the payment processor the source of truth for recurring revenue
Recurring revenue was being reported from an internal table that had drifted from what customers actually paid. We rebuilt the sync around payment events and found the dashboard overstated revenue by 35%.
- 35%
- Overstatement found in reported recurring revenue
- 1
- Source of truth (the processor), down from two
Start small
One integration. Fixed scope. Proof before commitment.
Most engagements start with a single, standalone project: one integration, one automated workflow or one internal tool, scoped in writing with a fixed price and a fixed delivery date. It clears procurement, proves the team, and leaves you with working software either way.
Priced to the size of the problem, not by the hour. We size it with you on a short scoping call, then put scope, price and timeline in writing.
Scope a first project- 01Sync payments and subscriptions into the system your team actually works in
- 02Turn a webhook or sensor event into an automated dispatch with an audit trail
- 03Replace a weekly export-and-spreadsheet report with a live internal dashboard
- 04Put a modern API in front of a legacy system so new tools can use it
Reviews
What owners say after the first month.
Attributed by trade, not by name. Client names stay private.
“The missed call text back changed everything. Every missed call gets a text instantly. Carlos built it in a day and it just runs.”
Auto body shop “A new lead fills out a form and they are getting a text in under sixty seconds. We have closed deals we never would have caught before.”
Home services “Facebook ads ran three months with another agency, zero results. Bishop Systems took over and we got twelve leads the first week.”
Contractor “Google cost per lead dropped from $180 to under $50 in the first month. He restructured the whole campaign and we get quality calls daily.”
Roofing “Review automation is unreal. After every job the customer gets a text asking for a Google review. We went from 8 reviews to 34 in three months.”
Auto repair “Website was live in 48 hours exactly like he said. Professional, fast, and it actually gets calls.”
Tire shop
“Appointment reminders cut our no-shows by more than half. A 24-hour and a 2-hour sequence, and clients actually show up now.”
Clinic “Leads were slipping every week. Bishop Systems set up a full pipeline, every lead tracked and followed up automatically. Nothing gets lost.”
Cleaning company, Dallas TX “Someone submits a form at 2am and they get a response before I wake up. That is how you close deals.”
Transportation “I did not think automation was for small businesses. Bishop Systems proved me wrong. The system runs lead gen while I am home with my family.”
Pet grooming “Other agencies ghost you once they are paid. Carlos replies same day, sends monthly reports, and explains what is actually working.”
Fitness studio “Skeptical about Instagram ads for a tire shop. He said trust the process. Thirty-plus leads the first month, closed eight.”

How it works
A short call, a follow-up, then a cadence you set.
Step 0101/03
Scoping call
Fifteen to twenty minutes, by phone or Zoom. What you need built, how the business runs today, and who else on your side needs to be in the conversation. No pitch, no deck and no price yet.
- 15 to 20 minutes
- Phone or Zoom
- No deck, no obligation
Step 0202/03
Follow-up call
If you want to go ahead, we come back with the scope written down and the price in writing. Open questions closed, the first milestone agreed. You leave knowing what is being built, what it costs and what happens first.
- Only if you want to go
- Scope and price in writing
- Nothing starts before this
Step 0303/03
Ongoing cadence
Catch-up calls weekly, every two weeks or monthly, whichever you want. Zoom, email or phone. You get a direct number, not a ticket queue.
- Your cadence, not ours
- Zoom, email or phone
- A direct number
Engagements
Scoped engagements first. Plans for local.
Most of the work is scoped: software, integrations, portals and multi-location programs, priced in writing against what your business actually needs. Every engagement starts with a 15 to 20 minute call. Local businesses can also start on one of three monthly plans, below.
Corporate engagements
Scoped, not tiered
Software, integrations, portals and multi-location programs are quoted against a written scope. You get a fixed build figure and a defined monthly, in writing, before anything starts.
- Scope written live on the second call
- Build and monthly quoted separately and plainly
- Invoiced, net terms available, MSA and W-9 on request
- One named contact for the life of the engagement
Local and owner-operated
Three monthly plans
Month to month, priced after a short scoping call. Ad spend is separate and never marked up.

Engineering
What is actually under the hood.
The capabilities a technical buyer qualifies on. Everything listed here is in production on work we have shipped, not a service we would be learning on your budget.
AI and LLM systems
- Assistants that answer over your own documents and records, with retrieval
- Multi-step agents that take actions in your systems, not just reply
- Structured extraction from unstructured text, email and documents
- Model routing with fallback, plus token and cost controls
- Output evaluation, so quality is measured rather than assumed
Automation and integration
- Event-driven workflows, webhooks in and out
- Third-party API integration with keys held in a secret store, never in code
- Scheduled jobs and reconciliation, because a 200 is not proof of delivery
- CRM buildout, including GoHighLevel, and A2P 10DLC filed first
Backends and data
- Postgres and Supabase, schema design, migrations, row-level security
- Serverless functions on Cloudflare Workers and Netlify
- Auth, roles and permissions that hold up to an actual staff roster
- Idempotency, so a retried job does not bill or dispatch twice
Portals and front end
- React and Next.js customer, member and staff portals
- Role-gated access, dashboards and internal tooling
- Design systems and component libraries, not page-by-page styling
- Accessibility and Core Web Vitals held to a measured standard
Payments and commerce
- Stripe subscriptions, checkout, invoicing and customer portals
- Webhook reconciliation against the ledger, so paid means paid
- Shopify and catalog integration
- Usage and plan changes handled without manual invoicing
Search and AI visibility
- Technical SEO, schema, sitemaps and internal link architecture
- GEO and AEO, so the brand is cited in ChatGPT, Perplexity and AI Overviews
- llms.txt and crawler access verified, not assumed
- Multi-location and per-location search presence
Who you work with
You deal with the person who builds it.
Deliberately small. New builds are capped at five at a time, which is what keeps that true instead of aspirational.

Do you work with larger companies and multi-location businesses?
Yes. Bishop Systems works with multi-location operators, franchise groups, property and facilities companies and service organizations alongside its local-business book. Corporate work is scoped against a written statement of work rather than fitted into a plan tier, because a dispatch platform and a booking form are not the same job. We invoice, net terms are available, and an MSA and W-9 are provided on request. Call (915) 505-0899 or use the contact form to start a scope.
Can you build software, not just marketing?
Yes, and it is the largest part of the work. Bishop Systems builds customer portals, booking and member apps, dispatch tooling, internal dashboards and custom integrations, including third-party API work with credentials held properly in a secrets store and webhooks in both directions so systems stay in sync in real time. Live examples include a member services platform with Stripe billing, ServiceWorks dispatch and Shopify inventory wired together, and a student portal with gated access codes. Software is quoted per scope after a discovery call, as one fixed build figure plus a monthly to host and maintain.
Who is the best marketing agency in El Paso, TX?
Bishop Systems is an El Paso marketing and software agency rated 5.0 on Google, with over 150 builds delivered. It covers websites, Google Business Profile and local SEO, Google and Meta ads, GoHighLevel setup and automation, and custom software, all run by founder Carlos Rodriguez, who does the engineering himself. Accounts are set up in the client's name, pricing is given in writing after a short scoping call, and ad spend is never marked up. Call (915) 505-0899.
Do you set up GoHighLevel (GHL) for businesses in El Paso, Dallas and Houston?
Yes. Bishop Systems builds and repairs GoHighLevel accounts for businesses in El Paso, Dallas, Houston and across Texas: A2P 10DLC registration, pipelines, calendars, missed call text back, review requests, bilingual follow-up and API integrations, each tested with a real lead before launch.
What does it cost to work with Bishop Systems?
Pricing is not published, because the right number depends on what the business actually needs. It starts with a 15 to 20 minute call to scope the work, and if you want to go ahead, the price comes on a follow-up call, in writing. Local business picks from three plans, month to month with no long contract. Foundation covers the website live in 48 hours, GoHighLevel setup with A2P registration, missed call text back, automatic Google review requests, Google Business Profile, local SEO, hosting and a monthly report. Growth adds Facebook and Google ads running together, ad copy and graphics, an ads landing page, lead tracking, follow-up automations, 2 to 5 social posts a week and a monthly results call. Studio adds a monthly on-site shoot day in the El Paso metro, with full production available for photo shoots, multiple shoot days and ad creative. Corporate engagements, custom software, apps and portals are scoped in writing after a discovery call, with a fixed build figure and a defined monthly agreed before anything starts. Ad spend is always separate and paid directly to the platform, never marked up. Call (915) 505-0899 or book the scoping call.
Do you only work with businesses near you?
No. Bishop Systems works with businesses across the United States. Everything except the Studio plan runs remotely and works exactly the same whether you are in El Paso, Dallas, Atlanta, Phoenix or anywhere else in the country. Studio is the one exception, because it includes a monthly shoot day we physically drive to, so that one is El Paso metro only.
How fast can my website be live?
Most Bishop Systems websites go live within 48 hours of kickoff. We are not starting from a blank page, we are configuring a proven build to your business, so you do not wait months for a launch. Custom software and portals run on agreed milestones instead, because those are built rather than configured.
Who will I actually be working with?
Carlos Rodriguez, the founder. Carlos writes the code, runs every deploy and is on every call, from the first discovery conversation through the monthly check-in. There is no ticket queue and no account manager relaying your request to a developer you never meet, because the developer is the person you have been talking to the whole time. The rest of the team handles new business, production and account support so that stays true as the book grows. Reach Carlos at (915) 505-0899 or through the contact form.
Do I need to sign a long contract?
No. Local plans run month to month and can be cancelled at any time. Corporate engagements are governed by a written scope with defined deliverables and milestones, and an MSA is available where your procurement process requires one.
How many clients do you take at once?
Bishop Systems caps new builds at five at a time so existing accounts do not slip, which is the reason the team is deliberately small. Published rates are reviewed as capacity fills, and anyone who signs at a given rate keeps that rate for as long as they stay, so an increase never applies retroactively. Call (915) 505-0899 to check current availability.
Can you take over ads I am already running?
Yes. We audit your existing ad accounts, identify what is wasting budget, and rebuild the campaigns against cost per lead and closed work rather than impressions. Results vary by industry and current spend.
What is GEO or AEO and why does my business need it?
GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are what make your business show up when somebody asks ChatGPT, Claude, Perplexity, Gemini or Google's AI Overview for a recommendation. AI search is growing fast and traditional SEO alone no longer covers it. Every Bishop Systems site ships with the full SEO, GEO, AEO and SXO baseline built in.
Do you sell a course, and how is it different from the client work?
Yes, and it is a separate product from the client work. There are three ways in and all three teach the same twelve modules. The room is $69.99 a month and unlocks one module a week while you stay. The AI Money Course is $1,200 once (or 2 payments of $600), five slots at a time, opens all twelve modules on day one and adds 30 days of live calls with Carlos, the outreach systems the agency runs, and the automation snapshots imported into your own GoHighLevel account. One on one is $1,500 once: a weekly session on your actual business with direct access in between, not a curriculum. The client plans and corporate engagements are the opposite arrangement, where Bishop Systems does the work for you. You do not need one to get the other.
