[ Benefits ]

An ERP that adapts to the way you work, not the other way around.

Off-the-shelf ERPs tend to impose their own rules, screens and processes.

We do the opposite.

We start from how your business actually runs and design a solution that matches your operational needs precisely.

Your business logic, respected

Discounts, approval workflows, specific calculations: the ERP applies your rules instead of making you adopt a vendor's.

A cost that doesn't scale with headcount

Bringing on a new team member adds no subscription: your budget follows your needs, not your user count.

Screens designed for every role

Sales reps, warehouse staff, accountants: each sees the information their job requires, with no unused menus to wade through.

Only what you actually need

No features paid for and never used: every module built answers a real need in your business.

Changes on your timeline

A new feature ships when your business needs it, not when a vendor's release calendar says so.

A solution you own

The code and data stay yours: no outside decision can call your tool into question.

Replace the software that forces its way of working on your teams!

We build as many custom modules as your business needs: management rules, business calculations, approval workflows, etc.

Discover the method in detail

[ Growth ]

An ERP that grows with your business and its needs.

We design architectures that can evolve with the changing needs of your business.

You can start with a focused scope, then add new modules step by step.

  1. Phase 1

    A first functional scope that addresses your most pressing needs.

  2. Phase 2

    Connection to your existing tools and process automation.

  3. Phase 3

    New modules, users, sites or entities added as you grow.

  4. Phase 4

    Fine-tuning, maintenance and continuous improvement.

[ Integrations ]

We build your ERP and integrate it with your information system.

Your ERP should never become yet another silo.

We connect your custom-built ERP to your entire digital environment and existing tools:

Your ERP

  • CRM
  • Accounting software
  • Banks
  • E‑commerce platforms
  • Logistics tools
  • Marketplaces
  • In‑house applications
  • APIs and third‑party services

We build the connectors needed to keep data flowing between all your systems.

These eight tools are only examples.

We connect your ERP to any software that offers an API or another way to exchange data: business tools, industry platforms, in-house systems, existing files or databases, etc.

[ Built-in AI ]

We add intelligence to your ERP.

AI can be built in wherever it delivers real value.

For example:

  • Automatic order entry

    Purchase orders received by email turned into sales orders to approve.

  • Supplier invoice capture

    Each invoice read, then matched to its purchase order and goods receipt.

  • Suggested account coding

    The nominal code and cost centre suggested for each invoice or credit note.

  • Demand forecasting

    Replenishment orders suggested based on sales and seasonality.

  • Purchasing decision support

    Supplier prices, lead times and track record compared before ordering.

  • Production schedule optimisation

    A schedule proposed around capacity, stock levels and due dates.

  • Anomaly detection

    Unusual discounts, margins and stock movements flagged.

  • Plain-language search

    A customer's outstanding balance or an item's stock level, just by asking.

  • Summary generation

    A monthly round-up drafted from sales, purchasing and stock data.

AI becomes a feature of your ERP, not a standalone tool.

Have an AI use case that isn't listed here?

These use cases are only examples.

We build AI in wherever it saves your teams time: assistants and agents, visual quality inspection, cash flow forecasting, product description generation, etc.
