01 — Services

What our custom software development company builds.

Most of our clients come to us with the same symptom: the business has outgrown its spreadsheets, and the SaaS tools it bought don't talk to each other. We replace that patchwork with software built around how your team actually works.

Custom ERP development

Lightweight ERPs for operations, inventory, purchasing, logistics and billing. We model your real workflow — approvals, roles, exceptions — and roll it out in phases so the business never stops.

→ Laravel · Node.js · PostgreSQL

CRMs & internal portals

Sales pipelines, customer and supplier portals, employee self-service and back-office tools with role-based access and a full audit trail.

→ React · Next.js · Tailwind CSS

Integrations & APIs

We connect your ERP, ecommerce, carriers, payment gateways and accounting so data flows once, automatically — no more copy-paste between systems.

→ REST · Webhooks · Queues

Dashboards & web applications

Web application development for KPI dashboards, scheduling, quoting and field operations — fast, secure and usable from any browser.

→ Next.js · AWS · Docker

Web & ecommerce

As an ecommerce development company we build fast storefronts — Shopify or headless on Next.js — with payments, shipping and inventory wired to your back office.

→ Shopify · Next.js · Headless

MVP development for startups

A focused first version you can put in front of users and investors, built on a stack that scales — so you iterate on version one instead of rewriting it.

Retail systems

Custom point of sale, real-time inventory across locations, loyalty programs and customer apps that share one source of truth.

Mobile apps

Manufacturing

Andon, ToolCrib, OEE and traceability for the shop floor live on our manufacturing software page.

02 — Featured work

Two systems, two very different problems.

Client names stay confidential, but the results don't. More projects — including the Andon and ToolCrib systems — are in our case studies.

Logistics · 2023

Operations portal

A custom lightweight ERP for shipment coordination. Carriers are integrated via API, customs documentation is generated by the system, and every route has its own KPI dashboard.

5Result: it replaced five shared Excel sheets and an internal email thread with one system of record.
Headless multi-brand online store storefront on desktop and mobile

Retail · 2025 · ecommerce/headless

Multi-brand headless store

One unified catalog for three sister brands, a mobile-optimized checkout and a shared admin panel — integrated with local payment gateways, shipping carriers and the client's existing ERP.

<1.2sResult: LCP under 1.2s, and one team managing three storefronts.

03 — Process

From whiteboard to production.

No black box. You see working software early and often, and you always know what's being built next and why.

01

Discovery

We map your process, users, data and existing systems, then agree on what the first release must do — and what can wait.

02

Design & architecture

Navigable prototypes your team can click through before a line of production code is written, plus an architecture sized for where you're going.

03

Build & QA

Two-week sprints with real demos. Automated tests, code review and CI from day one — quality is built in, not bolted on at the end.

04

Launch & support

Supervised deployment, data migration and training, followed by ongoing support and 24/7 monitoring for critical systems.

Timeline expectations: an integration or a focused MVP is usually measured in weeks; a custom ERP or multi-module platform is delivered in phases over several months, with the most valuable module going live first. You get a written scope and phased plan at the end of discovery.

04 — Engagement models

Three ways to work with us.

Software outsourcing to Mexico doesn't have to be all-or-nothing. Pick the model that matches how much of the work you want to own.

Model Project delivery Dedicated team Staff augmentation
Best for A defined system: ERP, portal, store, MVP An ongoing product roadmap Filling skill gaps in your team
Who manages We do, end to end Shared, with your product owner Your engineering leads
Scope Phased, agreed after discovery Flexible, sprint by sprint Your backlog
Scaling Per phase Up or down per quarter Per engineer

Want engineers who work only on your product? Read how our dedicated development team model works.

05 — Stack

Proven tools, no exotic lock-in.

We pick mainstream, well-supported technology so your system is easy to hire for and maintain long after launch. The code lives in your repositories and deploys to your cloud accounts.

06 — Why Mexico

Custom software development in Mexico, minus the distance.

Nearshore software outsourcing to Mexico works when the team actually shares your day. Ours does: we're in Mexicali, across from Calexico, on U.S. Pacific time and roughly two hours from San Diego.

  • Live standups and design reviews, not overnight handoffs.
  • Senior, English-fluent engineers; bilingual for teams on both sides of the border.
  • In-person kickoffs are a short drive or domestic flight away.
  • USMCA proximity keeps contracting and invoicing simple.

07 — FAQ

Common questions.

What does a custom software development company actually build?

Software shaped around the way your business already works instead of forcing you into an off-the-shelf tool. For us that means custom ERPs and CRMs, internal portals, integrations and APIs between the systems you already pay for, KPI dashboards, web applications, ecommerce stores and MVPs for startups.

When does custom software make more sense than off-the-shelf SaaS?

When your team is stitching several tools together with spreadsheets, email threads and manual re-entry, or when your process is the thing that sets you apart. If a standard product already covers most of your needs, we will tell you so and help you integrate it instead of rebuilding it.

How long does a custom software project take?

It depends on scope. A focused MVP or an integration is usually a matter of weeks, while a custom ERP is typically delivered in phases over several months. After discovery you get a written scope and a phased timeline, and you see working software in a demo every two weeks.

Who owns the code and the intellectual property?

You do. The code lives in your repositories, deploys to your cloud accounts and is documented so any competent team can maintain it. There is no lock-in to us.

Why outsource software development to Mexico instead of offshore?

Time zone and proximity. We work U.S. Pacific hours from Mexicali, about two hours from San Diego, with English-fluent senior engineers. Decisions happen in live calls instead of overnight handoffs, and USMCA proximity keeps contracting simple.

Can you take over or extend an existing system?

Yes. We start with a code and architecture review, stabilize what is critical, add tests and CI, and then continue building features. We can also plug a dedicated team into your existing engineering organization.
