Pesos are the balance shown with a ₱ mark. You get them by selling fruit. The game page says to harvest when the crop is fully grown and then sell.
The sell prompt can sell the whole inventory after you confirm. Read the total first. Size and rarity change it. The tutorial says bigger and rarer fruit sells for more. A rainbow mango in one session paid far more than an earlier sale of seven small fruits for ₱15. Those two sales are examples of the gap, not a price chart.
Spend pesos in this order while the farm is small:
- Seeds you still have plots and water for. The shop tags are the prices. The tutorial's ₱20 is only the first seed, not the price of every crop.
- A water bill, if one is open. An unpaid bill was a hard stop in one session.
- An egg from the pet trader, once fruit sales are steady.
- A sprinkler, basket, or Revive from the supply shop.
- A Land Office upgrade, after you have read the price on that button.
RELEASE adds 1,000 Pesos and BAHAYKUBO adds 500. The Rewards button lists another 2,500 for joining the nambawan group and liking the game. None of those replace selling fruit.
The harvest calculator only does arithmetic on numbers you type. It does not know the shop.
