Paper Money : The Vietnamese Imperial Age technology grants a payment of 500 gold for the researcher and their teammates.

Sultans : The Indians' Castle Age technology increases the speed of all gold income (mining, trading, and Relics) by +10%.

Several civilizations have unique technologies that give a one-time payment of gold upon researching them: Also the Indians unique technology, Sultans, allows Relics to generate 10% more gold. The Aztec team bonus increases relic gold generation by 33%. Relics can be picked up by Monks and put into a player's Monastery, where they will slowly generate gold. The Saracens have a reduction of the trading fee to 5% as one of their civilization bonuses. For many civilizations, the 30% fee can be reduced to 15% by researching Guilds. However, this includes a 30% fee and each time a resource is sold, the price of that resource will be lowered for all players. The Market allows the player to sell food, wood, or stone for gold. The Spanish team bonus increases the amount of gold returned by trade units by 33% (Now 25%), and also in The Forgotten, the Indian unique technology, Sultans, allows Trade Carts to produce 10% more gold.

Unlike in Age of Empires, trade does not require resources to be spent aside from the initial cost of the Trade Cart or Trade Cog. The farther the distance between the two docks, the more gold is generated.

Trade Cogs travel between docks to generate gold. The farther the distance between the two markets, the more gold is generated. Trade Carts travel between markets to generate gold.
