Technology · ERP & CRM

Run your business on a system that fits you.

Most ERPs and CRMs force your team to change how they work. We do the opposite. We map your real workflow first, choose the right foundation second, and only then we build.

The honest truth

Most ERP projects fail for predictable reasons.

Reason 1

Wrong tool for the job

A consultant sells you the platform they get commission on, not the one your business needs. You pay six figures for software that fits 60% of your workflow.

Reason 2

Process never gets mapped

Implementation starts before anyone really understands how your team works today. Three months in, the system contradicts how the warehouse actually operates.

Reason 3

Integrations as an afterthought

The ERP works in isolation. Six months later, you're paying someone $15K to connect it to Shopify, QuickBooks, and your shipping platform — work that should have been scoped from day one.

Reason 4

No one stays after launch

The implementation team disappears the day you go live. The first time something breaks, you're on your own — or paying support tickets at $200/hour to people who don't know your business.

We've been on the other side of these failures — as the engineers asked to fix them. That's why we work the way we do.

What we build

Three paths. One that fits you.

Path 01

Platform-based ERP

For standard operations

Your operation is mostly standard accounting, inventory, sales, and procurement. You don't need a custom build — you need the right platform deployed correctly. We implement, configure, and connect it to the rest of your stack.

Includes

Platform selection (NetSuite, SyteLine, QuickBooks Enterprise, others)
Configuration and customization within the platform
Data migration from your current system
Team training in English or Spanish

NetSuiteSyteLineQuickBooksManhattan WMS

Path 02

Custom CRM

For specific customer flows

HubSpot is too expensive. Salesforce is too complex. Sheet-based tracking is too fragile. You need a CRM built around how your sales and service team actually works — not a generic pipeline you have to wrestle with.

Includes

Custom-built lead and customer pipeline
Email, SMS, or WhatsApp automations triggered by your stages
Reports and dashboards that match how you actually measure
Mobile-friendly interface for sales reps in the field

Next.jsPythonMySQLREST APIs

Path 03

Hybrid build

For complex or binational ops

Your operation has standard parts (accounting, inventory) and unique parts (cross-border customs flow, custom packaging logic, vertical-specific compliance). We use a stable platform for the standard side and build custom modules for the parts no platform handles.

Includes everything from Path 01 and 02, plus

Custom modules connected to the platform via API or middleware
Integrations with binational systems (Mexican accounting, US compliance)
Documentation in both English and Spanish
Long-term support and growth plan

The process

We map. We choose. Then we build.

Discovery — 1 to 2 weeks

We sit with the people who actually use the system every day — not just the executives. Warehouse staff, sales reps, accounting, customer service. We document the real workflow, not the one in the org chart.

Output: a process map and recommendation memo. Yours to keep, even if you decide not to work with us.

Architecture — 1 week

We choose the path (platform, custom, or hybrid) and design the architecture. You see exactly what we're going to build, what it costs, what it takes, and how long. No surprises after the contract.

Output: technical proposal, fixed price or milestone-based budget, and a written timeline.

Build — 2 to 12 weeks

We work in two-week sprints with a working demo at the end of each sprint. You see progress weekly, not at the end. Adjustments happen along the way, not after launch when changes are expensive.

Output: working system, deployed in stages, with your team trained as we go.

Launch & support — 30 days included

We don't disappear after go-live. The first 30 days of support are included — bug fixes, team coaching, edge cases. After that, you can keep us on a monthly retainer or call us when you need us. No surprises.

Output: a running system, a trained team, and a partner you can reach.

A recent case

A clinic was paying for marketing it couldn't measure.

Custom CRM and analytics dashboard for a healthcare clinic

HealthcareHybrid build

Inbound patient inquiries arrived through phone, email, and social media — and disappeared. No tracking, no follow-up sequence, no centralized view. Marketing spend kept going up. Patient acquisition cost was invisible.

Our approach

·Mapped the patient journey from first inquiry to retained client
·Built a custom CRM to track every patient lifecycle stage
·Connected the CRM to the existing clinical engagement platform via API
·Automated follow-up sequences for non-converted leads

Currently in deployment. Full results case study coming soon.

Common questions

What people ask before signing.

Should I build a custom ERP or use a platform like NetSuite?+

It depends on your operation. If your processes are standard (accounting, inventory, sales), a platform like NetSuite, SyteLine, or QuickBooks Enterprise will be faster and cheaper. If your operation has workflows that don't fit any platform — like a binational logistics flow with custom customs documents — a hybrid build is often the right answer. We map this in the discovery call before quoting anything.

How long does an ERP or CRM project take?+

Smaller CRM deployments take 2 to 3 weeks. Mid-sized custom builds take 4 to 6 weeks. Full ERP integrations with multiple connected systems range 8 to 14 weeks. We give you a clear timeline after the free discovery call — no padding, no “it depends” without numbers.

Do you integrate with existing systems like Shopify, NetSuite, or QuickBooks?+

Yes. We've integrated NetSuite, Shopify, Manhattan WMS, QuickBooks, SPS, TrueCommerce, DSCO, Loop, and others using REST, SOAP, and EDI X12. If your system has an API or supports EDI, we can connect it.

What technology do you use to build custom systems?+

Backend in Python (FastAPI, Django) or Node.js depending on the case. Frontend in Next.js and React. Database in MySQL or PostgreSQL. Integrations through REST, SOAP, EDI X12, webhooks, and middleware where needed. We pick the right tool for the project, not the trendy one.

What happens after the project launches?+

Every project includes 30 days of post-launch support — bug fixes, team coaching, and edge cases. After that, you can either keep us on a monthly retainer or call us as needed. We don't lock you in. We earn the relationship.
