Custom back office
Your operation lives in spreadsheets and nobody knows which one is current.
- Roles & permissions
- Reports & exports
- Audit trail
Software studio · Buenos Aires
Proven systems,
ready for your
business.
We build and adapt platforms that already run in production: back offices, payments, CRMs, dashboards and AI integrations. The same engineering we ship for banks — applied to your company.
The systems
Eight systems.
One problem each.
Every system starts from a base proven in production and gets tailored to your operation — faster than building from zero, more yours than an off-the-shelf product.
Payments & bank integrations
Charging, reconciling and tracking payments eats hours of manual work.
- Transfers & Debin
- Automatic reconciliation
- Mercado Pago & gateways
CRM & invoicing
Clients, quotes and invoices scattered across email and WhatsApp.
- Pipeline & follow-ups
- Electronic invoicing
- Odoo or fully custom
E-commerce & catalogs
You sell well in person but your online channel does not convert.
- Catalog & stock
- Checkout & payments
- SEO-ready
Dashboards & reporting
The numbers exist, but getting a straight answer takes days.
- Real-time KPIs
- Scheduled reports
- Any data source
AI integrations
Repetitive answers and manual processing your team should not be doing.
- Support chatbots
- Document processing
- Workflow automation
Mobile apps
Your clients and field teams need you in their pocket, not on a desktop.
- iOS & Android, one codebase
- Offline-first
- Push notifications
Modernization & migrations
A legacy system nobody dares to touch is slowing the whole business down.
- .NET upgrades (6 → 8+)
- Move to cloud
- Zero-downtime strategy
Our products
We don't just build for others.
These are our SaaS.
Every product was born from a real problem. Ask for a guided demo of any of them — or for the one we should build for you.
Working MVP ★ Flagship
LogiFlow
Last-mile shipping management: API, admin panel and driver app.
SMBs running deliveries with spreadsheets and WhatsApp lose packages, hours and customers.
Working MVP
Inventario POS
Multi-warehouse inventory with an integrated, offline-first point of sale.
Small retailers lose sales to stockouts and run the register on paper or from memory.
Working MVP
Catálogo Digital + WhatsApp
Digital catalog with a QR menu and one-tap WhatsApp ordering — no e-commerce needed.
Local shops and restaurants take orders over WhatsApp with no menu, no cart and constant back-and-forth.
Working MVP
Sistema de Reservas
All-in-one booking for service businesses, synced with Google Calendar.
Salons, clinics and studios still book by phone and lose clients outside business hours.
Working MVP
ProMatch
Marketplace connecting trusted professionals with the people who need them.
Finding a reliable plumber, electrician or tutor still depends on word of mouth.
Working MVP
Sorpresas
Personalized balloon-reveal surprises, shareable by link.
Announcing big news — a pregnancy, a proposal — deserves more than a plain text message.
In development
FS.Framework — ERP
Business ERP with built-in AFIP electronic invoicing for Argentina.
Argentine SMBs juggle invoicing, stock and compliance across disconnected tools.
Working MVP
Invirtiendo
Personal finance with AI: track income, expenses and investments.
Bank statements and investment data live in PDFs nobody reads — AI turns them into decisions.
Working MVP

Property portfolio, contracts, due dates and rent/expense collection in one place.
Agencies and multi-unit owners track tenants, owners and payments across spreadsheets and lose sight of due dates.
Working MVP
Recurrly Pro
Membership management with recurring billing, access control and renewals.
Gyms, clubs and academies lose revenue chasing overdue payments and cutting off access by hand.
In development
Fidelización Digital
Digital points program that replaces paper stamp cards.

In development

AI-generated thumbnails for creators, in seconds.

Consistent corporate email signatures for the whole team.
Every employee improvises their signature and the brand pays for it.

Live, not mockups.
Sites and systems delivered to real clients — health, hospitality, legal, retail and food — all in production today.

E-commerce for artisanal frozen chipá, ready to bake in 10 minutes.
The brand sold through Instagram, with no storefront or a simple way to take orders.
In production

Site for a beauty and aesthetics studio, with bookings.
