From workshop
to enterprise.
A single operating system for technical service in LatAm. Multi-tenant, real-time, in production today. Replaces WhatsApp + Excel + loose PDFs with enterprise-grade traceability.
The problem isn't WhatsApp.
It's that nobody knows where each ticket stands.
A mid-sized shop handles 30 to 50 active tickets at any given time. Each one involves at least 4 people: the customer who reports, the admin who assigns, the technician in the field, and the end-client account owner waiting for an update. When that chain breaks — and it breaks every day — you lose money, reputation, and technicians.
My business is on WhatsApp, in a notebook, and in the head of the technician who quit last month.— Shop owner, LatAm 2024
The villain
Competition isn't your villain. The villain is operational chaos — distributed across WhatsApp, Excel, and the head of your star technician.
Where the chain breaks
Eight actors who depend on each other. Eight points where information gets lost — and nobody has a central system to track it. Here are the 4 main ones:
Asks on WhatsApp 3 times. Nobody answers because nobody knows.
Sends a WhatsApp. The tech replies 4 hours later. Or doesn't.
Found out via the customer's WhatsApp. The office didn't know.
Pedro is on another site. Nobody knows where the part physically is.
And the chain doesn't end there. Four more actors have no visibility either — and each one pays the cost in their own way:
The prospect requested a quote 2 weeks ago. Nobody knows if it was answered, closed, or fell asleep.
The work is done. The client doesn't remember anymore. The invoice was never sent — discovered a month later.
No dashboard. Asks admin to send an Excel. Arrives 3 days later, with stale data.
Tech tells admin. Admin tells purchasing. Purchasing calls supplier 3 days late. Part arrives when it's no longer urgent.
8 actors who depend on each other. Without a central system, every handoff is an opportunity to lose money, time, or a customer.
Six moments that happen every single day
If you run a shop, at least one (or all six) of these sounds familiar. Each has a concrete cost in lost hours, unbilled revenue, and customers walking away.
The customer calls and nobody knows the status
The regional manager of a supermarket chain asks about their walk-in freezer. You say "let me check with the tech and get back to you". Four hours later the tech says "almost done". The customer lost the morning waiting.
The tech arrives without context
The technician drives 40 minutes to the client's site. When he arrives, he realizes he needs a specific part he didn't bring. Back to the shop. That lost day is worth ~$300 in labor, fuel and missed opportunity.
An approved quote sits idle
The customer approves the quote via WhatsApp on Monday. The admin doesn't tell the tech until Thursday. 3 days of lost revenue. Meanwhile, the customer thinks "these guys aren't serious" and starts talking to a competitor.
The job got done and nobody billed it
The tech finished the repair. Left. Closed the ticket in his head. But nobody issued an invoice. A month later you find out the work was done, never paid, and the customer doesn't even remember. You go fight for it and it looks bad.
The part was ordered but nobody knows where it is
"Yes, we ordered that two weeks ago." From which supplier? On what date exactly? Did it arrive? In which warehouse? Without traceability, parts get lost, double-ordered, or sit on a shelf unused.
The end-client asks for a report and you build it by hand
The corporate customer requests the QBR: "How many interventions did you do across my 30 locations this quarter?". An admin spends half a day building the spreadsheet. The customer glances at it for 2 minutes and never asks again. The effort goes unbilled.
The cost of no traceability
It's not an intangible cost. The industry measures it. These are the numbers any serious Field Service study documents.
Every role in the chain says it
It's not just the owner's problem. Every actor feels it — and they all express it with the same frustration.
"I have 8 technicians on the road and I don't know which one is at which client right now."— Owner · industrial refrigeration shop, GT
"I show up at a site without knowing what they did last time. I end up asking the customer."— Technician · 12 years on the job, CR
"I don't want to chat with a technician on WhatsApp. I want a portal where I can see the status of my 30 units."— Operations manager · retail chain, PA
This translates into three lines on the P&L:
Jobs that got done and never billed. Approved quotes that took a week to execute.
Re-visits paid by the company. Duplicated or lost parts. Avoidable overtime.
Customers leaving for a "more professional" competitor. Each one costs 5× more to replace than to keep.
McKinsey: lifting customer satisfaction from "poor" to "excellent" reduces churn by 75% and triples 3-year revenue growth.
A huge sector — attackable
from six verticals at once.
We're not chasing a niche. Nodux works in any industry where someone breaks something, someone else fixes it and bills for it. Each vertical replicates the same operational flow: ticket → tech → customer → payment. This is the combined TAM documented in public reports:
More verticals Nodux supports today
These aren't aspirational — they're industries with consolidated market data and growing demand. Each one replicates the ticket flow Nodux already solves.
Auto repair · South America
$32.9B
USD annually (2024). Brazil + Mexico = 70%+ of the market. Dominated by independent shops.
Consumer electronics
$25.4B
USD globally in electronics repair in 2025. Right-to-repair pushes the sector up.
Commercial kitchen
$12.8B
USD globally by 2035 in industrial kitchen equipment maintenance. CAGR 5%.
FSM software · Global
$5.6B
USD in field service management software in 2025. SMB CAGR: 10-16%.
COMBINED ADDRESSABLE TAM
USD annually globally adding up the technical-service verticals Nodux works in today. Regional concentration: Brazil + Mexico move 70%+ of the LatAm market — sector dominated by independent shops with no software, not by chains with proprietary systems.
AI disrupts desk work.
Skilled trades stay human.
In 2026, every VC asks the same question: "does this survive AI?". Nodux operates in one of the few sectors where the answer is yes — because physical repair doesn't dematerialize.
Not replicable by AI
Repair requires physical presence, manual dexterity, and tactile diagnosis. AI doesn't hear a compressor's noise or feel a motor's vibration — and won't in the next 5-10 years.
Growing demand, not shrinking
Fleets age, industrial equipment keeps breaking. While other sectors contract under automation, technical service grows year over year — independent of the tech cycle.
AI amplifies, doesn't replace
AI ticket triage, failure prediction, agentic copilots for technicians. Nodux is the rail it runs on — the operating system amplifies the human technician's value instead of competing against them.
While AI replaces admin tasks, accounting, and junior code — the technician who repairs a refrigeration unit on-site stays human. And needs an operating system worthy of the trade.
Fragmentation = opportunity
Unlike the US, where chains dominate, LatAm is 100% independent shops. There's no Square or Toast for technical service. That's the opening.
Growing demand
Aging fleet + expanding middle class + used-vehicle demand + healthcare scaling. Technical service consumption in LatAm grows year over year.
Horizontal expansion
Each new vertical doesn't require a refactor — just a taxonomy template. Nodux scales sideways without rebuilding core every time we enter a new industry.

Nodux vs the rest
Compared against the real alternatives a LatAm repair shop owner evaluates today:
Salesforce FSL and ServiceTitan are US enterprise products — excellent but designed for US customers, not LatAm. Excel + WhatsApp is free, but the real cost is paid in lost hours (see Slide 01).
Not a promise.
It's what the industry documents.
Field service management software has consolidated impact benchmarks that any industry study documents. These are the numbers a serious shop can expect by moving from WhatsApp + Excel to a platform like Nodux.
-15 to 30%
Lower fuel costs with optimized routing. Up to $300/month saved per technician.
-20 to 25%
Less time on the road. More billable hours. Same fleet, more tickets closed.
-100%
Paper eliminated. $500+/month saved in printing + admin time digitizing things by hand.
-20 to 30%
Less overtime. Smart dispatch reduces re-visits and end-of-day overruns.
Numbers from the global Field Service Management sector — applicable to any shop moving from manual to digital. Nodux delivers the same benefits without paying for Salesforce.
You pay $299/month.
You recover ~$2,000/month.
We apply sector benchmarks to an average Growth-tier shop in LatAm — 5 technicians in the field, ~30 active tickets per month, regional operation. These are the concrete monthly savings Nodux delivers:
+20% PRODUCTIVITY
USD / month in recovered capacity
5 techs × 20% more capacity = effectively 1 extra technician without hiring. Mobile dispatch + real-time data.
-25% ROUTE + FUEL
USD / month in logistics
5 techs × ~$300/month in fuel × 25% reduction. More billable hours, fewer dead miles.
-18% RE-VISITS
USD / month in rework
30 tickets × 18% fewer re-visits × ~$60 cost each. First-time fix rate climbs from 77% to 95%.
AUTOMATIC REPORTING
USD / month in admin hours
Reports to corporate clients: half a day → 30 seconds. ~2 reports/month × 4 hours × $15/h.

Payback
To recover the monthly cost
Year 1 net benefit: +$22,000 USD
Annual plan cost: $3,588. Estimated annual savings: ~$25,680. And that doesn't count additional revenue from new B2B contracts won thanks to enterprise-grade traceability.
Indicative calculation applying FSM sector benchmarks to an average LatAm shop with 5 technicians. Real ROI varies with volume, vertical and operational maturity — but the direction is consistent: the plan pays for itself in the first month.

If your business is "someone breaks something, you fix it and bill for it" — Nodux works for you.
Your customer services Coca-Cola.
We give them the tools to look enterprise.
Most of our anchor customers don't sell to end consumers. They provide rental, support and maintenance to large commercial enterprises: supermarket chains, industrial plants, banks, hospitals, hotels. Nodux is the layer that lets them sell to that kind of customer — and keep them.
Your customer looks like "a tech guy"
- Sends WhatsApp photos to Coca-Cola
- Quotes with a hand-made PDF
- No documented asset history
- Doesn't measure SLA — the customer does
- Loses the contract when a "more professional" competitor shows up
Your customer looks like a strategic vendor
- Sends Coca-Cola a portal link: live view of all their assets
- Quotes from the system → customer approves with one click
- Full history per asset: when repaired, what changed
- SLA measured live — the customer sees it before asking
- Wins new contracts by already looking enterprise-grade
Nodux's "ace"
Hybrid traceability: works whether your client uses it or not.
The universal shop objection is "my clients won't use another app". Fair. Some corporate clients want modern self-service; others prefer a weekly status email and ad-hoc reports. Nodux works in both scenarios — without changing anything on the shop's side.
IF THE CLIENT OPTS IN
You send them a portal link. They see their assets, ticket status, history, live SLA. Approve quotes in one click. Zero friction — no account creation, no app download.
IF THE CLIENT WANTS NOTHING NEW
The shop still tracks everything internally: per-asset history, SLA, interventions, costs. You send the PDF/Excel report when requested — built in 30 seconds instead of half a day.
The shop adopts Nodux even if none of its end-clients ever open the app. Traceability lives where it's needed: the shop. The end-client is an upside, not a requirement.
Real use cases from our anchors
These are the flows already in production with the customers migrating now:
Supermarket chain
Preventive + corrective maintenance of refrigeration units across 30 locations. The regional manager sees each unit's status live from a single link — no report requests.
Industrial plant
Calibration + repair of scales, weights and measurement equipment. Each asset has its full history: last calibration, by whom, what was changed, next due date. ISO-auditable.
Hotel / Hospital
HVAC, electrical, kitchen-equipment maintenance. The facilities manager approves quotes from their phone and sees what's happening on each floor, live.
Corporate fleet
Mechanical service + tires for company fleets. The logistics manager sees which vehicle is in repair, when it's back, and how SLA is tracking in a single dashboard.
Bank / Retail chain
Maintenance of ATMs, POS, distributed thermal printers. Per-location SLA + automatic reporting for the end-client's QBRs.
Service stations
Pump calibration, POS maintenance. Automatic regulatory reporting that used to take a day to assemble in Excel.
Nodux isn't just software for the shop.
It's the tool that lets them sell upmarket.

- You send a link, the client sees everything live
- The operation stays documented — independent of any technician
- You win enterprise contracts you didn't qualify for before
- The business scales without multiplying your workload
You're not a technician with a spreadsheet.
You operate a system.

The questions everyone asks
before they start.
The real objections we get on WhatsApp every week — and our honest answers.
Will my team (technicians, sales) actually use it? They're anti-tech.
Yes. Nodux is designed mobile-first — your technician opens the app from their phone, sees their tickets, uploads photos, logs expenses, and closes. No manuals, no training. For sales reps, the flow is WhatsApp/call/email with 1 click from the client list. Learning curve is 1 day.
Do I need to install anything or run my own server?
Nothing. Nodux is a PWA — you open app.nodux.link on your phone or computer and you're in. If you want, install it as a native app with 1 click (iOS and Android), no App Store or Play Store required. Zero infrastructure on your side.
What if I want to leave? Is my data locked in?
Your data is yours. Export clients, tickets, quotes, and inventory to CSV/Excel whenever you want — without asking permission. No contract lock-in: pay monthly (or annually with a discount) and leave if it doesn't work.
Does it work if my technician loses signal on a site visit?
You can read tickets offline today. Offline write + auto-sync is on the immediate roadmap. If your tech goes to a no-signal zone, opening the ticket before leaving caches everything.
How do I pay from Costa Rica / Guatemala / Mexico / Colombia?
International card, SWIFT transfer, or PayPal. You're billed in USD (electronic invoice from Nodux Tech LLC, based in Cartago, CR). If you need a local invoice in your country, we coordinate over WhatsApp.
I have Pipedrive / Jobber / ServiceTitan. Why switch?
Those are US/EU tools — they cost 2-5× more, they're in English, and they don't get the LatAm workflow (WhatsApp as primary channel, country-specific VAT, support in local timezone). Nodux is 1 single app that replaces Pipedrive + Jobber + your inventory Excel for less than the price of one of them.
Is there a free trial or live demo?
Yes. 30-minute personalized demo on Google Meet (we walk you through Nodux with a real case from your industry). If you sign up, the first 14 days are free — no card, no tricks. Direct WhatsApp support during onboarding.
Why we built this
Built from a workshop, not from a Silicon Valley office. Nodux was born at Nexius because we lived operational chaos firsthand. We know the problem because we suffered through it. We built the tool that would have saved us years of Sundays chasing WhatsApps.
Start your transformation.
14 days free. We import your Excel. Your team operates in a week. No annual contract. No setup fee.
