Non-PRO English to French Marketing Construction / Civil Engineering

Bonjour à tous,

sauriez-vous comment traduire "low-points" dans le contexte ci-dessous:

The benefits of using the system are numerous: manageable cashflow low-points, fast erection of
homes, flexibility to adjust unit designs to suit each site, less labour and machinery is required (resulting in less disturbance to existing residents) and potentially much higher profitability.

Merci

Anne
