If the Company enjoyed the privilege of trade with Caracas, the Royal Treasury also benefited from its economic capacity. During the first stage, the Guipuzcoana de Caracas company was in charge of the arms stores in Placencia, being the one that signed the contract with the monarch. It was also entrusted with the supply of ironwork for the Havana shipyards (an operation that the Royal Company of Havana assumed from 1740 onwards). And when the Company had to move its headquarters to Madrid, it became subject to greater services to the Royal Treasury, beyond its commercial operations.
The agreements signed the Treasury and Company from 1752 onwards were very varied: supply of slaves, fishing in Cuman, wood from the mountains of Navarre for the construction of units for the Navy, acquisition of goods from Spanish factories (brandy from Navarre and blankets from the "Spanish factories", thus ensuring the exit of national goods that were otherwise subject to competition from other foreign products), production of snuff, etc. These and other operations diversified the company's own objectives excessively, making it unable to focus its activity on its purely commercial interests.
