Understanding these figures
What does a contract’s amount measure?
A contract’s amount is the maximum allowed over its whole term, often several years: it is not what the town spends in the year. The lots of one contract are grouped.
Where do these figures come from?
Contracts above €40,000 excluding VAT, as declared when they are awarded (DECP): contract amounts, not payments. Smaller contracts are not published; obviously wrong amounts are set aside.
