They publish about 0.6 tenders a month, measured over 67 months of history.
Half of their 25 awarded contracts are worth €300k or less — size your bid to that range.
Most of their buying falls in sewage, refuse, cleaning and environmental services, construction work, administration, defence and social security services.
Their most frequent suppliers are SEMAER (3), SEMAVERT (3), VETIPRO (2) — expect to bid against incumbents who already know this buyer.
