Chapter 7: Trade and Commerce

As outlined under Starship Revenues in Chapter 6: Off-World Travel, a vessel can easily haul cargo for a flat rate, without having to engage in speculative trading. However, for those merchants willing to take the risk, speculative trading can prove to be a very profitable enterprise. This chapter provides a simple speculative trade system for use in Cepheus Engine campaigns, for those interested in such pursuits.

Speculative Trade Checklist

Speculative trading follows a basic procedure. The following checklist outlines the various steps in the speculative trade procedure:

  1. Find a supplier
  2. Determine goods available
  3. Determine purchase price
  4. Take goods to new world or market
  5. Find a buyer
  6. Determine sales price

Find a Supplier

The first step in the process is simple: find a supplier with something to sell. Characters can search for multiple suppliers, but there is a –1 DM per previous attempt on a planet in a given month.

Finding a supplier
Broker, Education or Social Standing, 1D6 days, Average (+0)
Finding a black market supplier
(Illegal goods only) Streetwise, Education or Social Standing, 1D6 days, Average (+0)
Finding an online supplier
(Worlds with TL 8+ only) Computers, Education, 1D6 hours, Average (+0)

The size of the Starport provides a bonus to finding a supplier:

Class A starport
+6 DM
Class B starport
+4 DM
Class C starport
+2 DM

Determine Goods Available

Goods are divided into two categories of goods – Common and Trade Goods. Common Goods can be purchased on any world. Trade Goods can usually only be found on a world with a matching trade code. The amount of each type of goods available is limited – the tons column on the Trade Goods table determines how many tons of a given type of goods is available for purchase.

A given supplier has all Common Goods available and 1D6 randomly determined goods. Roll D66 on the table to determine the goods available, ignoring results 61–65 unless dealing with a black market supplier. If you roll the same type of goods multiple times, then the supplier has extra amounts of those goods available.

Some goods are illegal, and can be purchased only through a black market supplier. A black market supplier has whatever illegal goods match his world's trade code, as well as any randomly rolled illegal goods. Other goods may be legal on some worlds, but not legal on others (such as personal weapons and armor, which might be restricted on a world with a high law level).

66 Unusual Cargo * * * *

Note: Unusual cargo covers unique or highly unusual items, such as alien artifacts, high tech prototypes, stolen artwork of antiquity, or unique lifeforms. Such items often form the seed for an adventure.

Determine Purchase Price

Determining the purchase price for speculative cargo is based on the results of a skill check. The results of this skill check represents the best possible offer the parties can reach under the current conditions.

Determining the purchase price
Broker, Intelligence or Social Standing, 1D6 kiloseconds, Average (+0)

The skill check is further modified by adding the largest Dice Modifier that applies from the Purchase DM column, subtracting the largest Dice Modifier that applies from the Sale DM column, and subtracting any Dice Modifiers from the supplier (such as their Broker skill). Some especially rich or powerful suppliers can demand high prices. In cases where multiple Purchase or Sale DMs apply, use only the largest ones from each column.

Modified Price Table

Modified Price Table
Result Purchase Sale
2- 200% 40%
3 180% 50%
4 160% 60%
5 140% 70%
6 120% 80%
7 110% 90%
8 100% 100%
9 90% 110%
10 80% 120%
11 70% 140%
12 60% 160%
13 50% 180%
14 40% 200%
15 30% 300%
16+ 20% 400%

The Referee should consult the Purchase column of the Modified Price table, using the skill check result to determine the Purchase Price percentage. The final price of the speculative cargo is the Base Price multiplied by the Purchase Price percentage.

Rejection Penalty
If the trader does not accept this price, he cannot deal with that supplier again for at least one week. After that week, he may attempt a new skill check.

Local Brokers

A speculative trader can hire a local broker to represent him in trade negotiations. This allows the merchant to use the broker's skill levels instead of their own, although that comes at a price in the form of a percentage of the final negotiated price, which must be paid even if the merchant decides not to sell his goods.

Local Brokers
Skill Level Commission Notes
1 5% Max for Class D or E Starport
2 10% Max for Class C Starport
3 15% Max for Class B Starport
4 20% Max for Class A Starport

Selling Goods

Selling goods works just like purchasing goods, with the following changes:

  • A character must find a buyer, instead of a supplier. The same rules apply.
  • When selling goods, add the largest Sale DMs for the world trade code and subtract the largest Purchase DMs.
  • If a character does not accept the price offered for his goods, he must find another buyer or wait a week, in which case he may attempt a new skill check to determine the selling price.
