Software built by us, already running in real businesses.
We don't just deploy third-party ERPs. We develop our own products (a3buddy with AI, facturak2 coming soon) and bespoke applications that are already live today in warehouses, production plants and offices. If you need it and it doesn't exist, we build it.

A sample of the areas where we have spent years delivering custom software in real production environments, not in presentations.
Warehouse PDA apps
Android on Zebra, Honeywell or Datalogic terminals. Picking, bin location, cycle counting, goods receipt and dispatch. Integrated in real time with A3ERP, SAP Business One or your ERP.
Production software
Work orders, quality control, batch traceability, bills of materials, shop-floor scanning. Data capture via tablet, industrial terminal or fixed station. Pushed to the ERP instantly.
Custom planning and MRP
Visual production schedules, resource assignment, order sequencing, aggregate capacity. Editable by your team without having to request changes from us every week.
Custom integrations
Your ERP connected to an online shop, marketplace, bank, carrier or key customer or supplier. EDI, REST API, custom formats — without changing your core system.
Custom dashboards and BI
Management dashboards with real business data, connected to your ERP. Commercial, financial or operational KPIs at a glance, without exporting to Excel every Monday.
Automation and applied AI
Repetitive processes — supplier invoices, reconciliations, ticket classification, data extraction — resolved with scripts and, where it adds value, with real AI running on your own data.
Why build software with us
20+ years with SMBs
We have seen the common problems of industrial, distribution and service companies. We don't improvise.
ERP specialists
A3ERP, SAP Business One, Sage Murano, Microsoft Business Central. What we build genuinely integrates with what you already have.
AI applied to development
Faster delivery and better quality thanks to AI at every stage, without the cost increasing for you.
Ongoing support, not abandonment
The day after deployment we are still with you. No forced contracts, no disappearing act six months in.
