Plans are a flat price, not a meter
Many hosts start cheap and then bill bandwidth, build minutes, seats, or requests. The invoice changes when the site gets traffic. PALM Ops does not work that way.
Plot is two sites. Grove is eight. Canopy is twenty. The price on the billing page is the monthly price. Choosing a plan records that choice for the wallet. It does not charge a card in the panel.
During the free 48 hours the site limit stays at eight, even if you have already picked a smaller plan. After the trial, the plan’s site limit applies. The server also has its own overall cap.
If you need more sites, you choose a larger plan. You do not buy extra gigabytes of transfer.
