Plan
Planning that knows your crews and stock.
Stock checked before you schedule.
You see straight away whether all materials are in. No crew leaves for nothing.
Who can do what.
Skills, certificates with expiry dates and absences per employee. A job only goes to someone allowed to do it.
What's left, and the customer knows.
The jobs still to be scheduled sit next to the planning. Drag the job onto a crew and the customer gets a confirmation by text or email.
- Separate calendars for sales, surveys, installation and electricians
- Map with routes
- Crews grouped by region
- Print day and week plans
Buy
Order what you need. Nothing more.
The purchase calculator looks at your open orders, your stock, your minimum stock and what's already on order. It rounds up to pallets and boxes and makes one purchase order per supplier.
Rounded to how your supplier delivers.
Pack sizes and minimum order quantities are part of the calculation.
One click, every purchase order.
Goods receipt, purchase invoice and an alert when a delivery is late follow on their own.
- Multiple warehouses
- Stock counts
- Serial numbers per panel and inverter
- Pick lists for roof crew and electrician
- Self-billing for subcontractors
Inspect
Inspection and grid registration without paperwork.
Request the electrical inspection from the order. Once it's approved, HappERP registers the installation with Fluvius, with a single-line diagram it draws itself. The status comes back to the file on its own.
Electronically or by email.
The request goes straight to the inspection body, and the certificate appears in the file.
Rejected? Request again.
The report is in the file and you request a re-inspection with the same button.
Your customer helps.
Your customer fills in the details for the registration themselves through HappPortal.

Invoiced sooner, paid sooner.
Deposits settled automatically.
Deposit invoices, partial invoices, combined invoices and credit notes, all linked to the order.
Pay with the banking app.
