Three things you build yourself

Other ERPs let you pick from their settings. In HappCore you draw your own process, without writing code.

  • States, transitions, conditions and actions, in a diagram you see grow
  • An order can wait for payment and delivery at the same time
  • Export a workflow and load it into another environment

Every action you needMissing one? We build it for you, as your own action in your workflow.

Adaptable right down to the core.

HappCore is built from plugins. You take what you need, and what isn't there yet, we build.

  • Everything is a plugin.

    Sales, products, tasks and time registration are each a separate plugin. What you don't use stays out of your way.

  • Even the built-in rules.

    Does a standard calculation or step not match the way you work? We replace it for your company, without a separate version of HappCore.

  • Sales✓AvailableQuote, order, delivery and invoice, with price lists per customer.
  • Products✓AvailableProduct families with your own attributes and EAN codes.
  • Organisation✓AvailableMultiple companies and brands, each with its own logo and numbering.
  • Time registration✓AvailableA month of hours becomes an invoice in one click, in the customer's language.
  • Tasks✓AvailableAssign and follow up tasks, with an email notification.
  • Peppol through Billit✓AvailableE-invoices go out from the workflow, with a payment QR.
  • PlanningComing soonCrews, calendars and the map.
  • CalculatorsComing soonBills of materials for solar panels, batteries and more.
  • Stock and warehousesComing soonInventory, counts and serial numbers.
  • PurchasingComing soonPurchase orders, receipts and purchase invoices.
  • Your pluginYour own integration, action or calculation, built for your company.

Planning, calculators, stock and purchasing are on their way as plugins. You add them when you need them.

An ERP built on its API

Every screen in HappCore runs on the same API you can use. So everything you do in the app, you can also do from your own software.

  • Headless if you want.

    Run HappCore behind your own webshop, portal or app. Your users never have to see HappCore.

  • Separate keys per integration.

    Create a key per application in the settings and revoke it whenever you like. Every request is logged.

  • Ready for your AI agents.

    An agent that creates quotes or follows up invoices uses the same API as your team.

Yours, and always verifiable.

An ERP you run your whole company on has to be one you can trust.

  • Your own environment.

    Every customer gets their own installation and their own database.

  • Permissions down to the button.

    Roles with fine-grained permissions. What you're not allowed to do, you don't see.

  • Every change kept.

    Everything is stored: who changed what, from which value to which, for every record.

HappERP or HappCore?

HappERP has everything for green energy built in. HappCore lets you shape everything yourself. HappQuote, HappPortal and HappField work with both.
