Tips on how to earn extra income
Campaign :Produce extra goods when you reach higher tier
Example
You we're selling mass produce linen when you advanced and able to produce leather jacket mass production it and sell it to make more income
Also don't sell it directly to the npc harbour...each time you sell reduces 1/5 of the price. Instead sell it on your harbour and let them come to you
If possible get to envoy products. Coffee sells good and perfume is insane
Senario :Same as above and if you have honour to spare upgrade your npc's trade fleet
Each level adds more ships for them to come more often and more budget for their expenses
Also about selling stuffs in your harbour

Passive selling screen:
When you click crate+coin icon, you will see something like the thing here on the right. You click "+" sign to pick a good to be passively bought (almost never worth it). You click "-" sign to pick a good for sales (up to 8 goods when you upgrade your Warehouse to last level).

After you click the "-" you will be asked to pick particular good and later a slider will show up allowing you to set how many of each good you want to keep in your Warehouse. On the image I set amount to 20 which means my Warehouse will only sell goods if there are more than 20 and sell only those who are surplus.
In short if I have 34 Rope and have 20 set to be kept, my Warehouse will sell only extra 14 of it. It's very handy to prevent NPC ships from emptying your stockpiles of food and building materials. The number in red under goods picture shows how many of goods are to be sold, for example for Tools here I have surplus of 90 to be traded.The pile of gold icon above the slider once clicked opens another slider that allows you to manipulate selling (or buying) price of that particular good. Average prices are find very well balanced so I usually don't temper with them. You may want to consider setting prices of goods you really have tons of (Wood, Stone?) to lower values so NPC buy more of them and increase prices of goods you don't have many of to get better bargain on them.
The top of the screen here shows last deals, it's worth checking out time to time to see what sells best and what doesn't sell at all. Should give hint how to set prices.
This way you can control how much to sell and at the same time keep your economy flowing and not dying
