Services
From an internal workflow to a full operation: we build the software your process actually needs — with automation, control and clear UX.
Manual spreadsheets, lost versions and rework become software with a defined flow, automations and data in one place.
Web systems, admin panels, SaaS and custom platforms — from an internal workflow to a full operation, with APIs, automations and integrations.
Custom systems
We don't ship generic templates. We understand how the company operates and build software, panels, platforms and integrations that match what you actually need to run.
If the operation still lives in a spreadsheet — messy Excel, endless tabs, the wrong version — ArcDux turns that into a system with automations, permissions and visibility. Bring the requirement: management, CRM, client area, or a flow no off-the-shelf tool covers.
I want to build my projectWhen it fits
If the operation still runs on a spreadsheet or the process doesn't fit a ready-made tool, it starts with how the company actually works.
“Our operation still lives in Excel”
“Our process doesn't fit a ready-made tool”
“I need to follow the operation”
“I need to integrate systems”
Operation
Decision-makers don't buy code. They buy control: less rework, fewer errors, and an operation you can follow without opening five spreadsheets.
Before
After
The more the operation grows on spreadsheets, the more expensive rework becomes. The time to structure it is now — before volume raises the risk.

Frequent releases with defined scope and full visibility.

FAQ
Straight answers about pricing, timelines and how we work.
Investment varies by scope, complexity and timeline. Simple projects or MVPs can start at lower ranges; operational platforms and enterprise integrations require more engineering. After understanding your context, we send a proposal with scope, milestones and pricing — no commitment.
It depends on size and how mature the idea is. MVPs and lean tools can ship in a few weeks; larger systems follow incremental delivery with frequent releases over months. We define clear milestones during discovery.
Yes. We work from a product's first version to operations already running at scale. You don't need finalized requirements — we help structure the technical path from what you already know about the business.
Fill out the form or reach us on WhatsApp. Within one business day we reply with technical questions, an initial architecture view and next steps. If it makes sense for both sides, we follow up with a detailed proposal.
Yes. Many clients stay with us for continuous product evolution — fixes, new features, monitoring and optimizations as the business grows.
Yes. A lot of operations still run on Excel or Google Sheets — wrong versions, rework and error risk. We structure the workflow and build the system with automations, permissions and history in place of the spreadsheet.
We build to spec. If your process doesn't fit a template or an off-the-shelf product, we structure the scope and develop the system — management, CRM, dashboard, platform, client area or an integration with what you already use.
