In the counting houses of Waterdeep, where gold flows as freely as wine in the Yawning Portal, one truth holds above all others: accurate ledgers separate thriving guilds from those that crumble into debt. The Waterdeep Trading Company has built its reputation not just on shrewd deals and reliable caravans, but on a foundation of sound accounting principles that guide every transaction, every contract, and every coin counted.

These principles are not mere suggestions scrawled by nervous scribes. They are the bedrock of financial truth, the standards by which the company measures its prosperity and protects its interests across the Sword Coast and beyond. From the bustling markets of Baldur’s Gate to the arcane bazaars of Silverymoon, these rules ensure that every silver piece is accounted for and every obligation is honored.

Understanding these principles is essential for anyone who handles the company’s coin, whether you are a junior ledger keeper, a warehouse master, a caravan captain, or a guild factor negotiating trade agreements in distant cities. They provide consistency, clarity, and confidence in a world where fortunes can shift as quickly as the winds over the Sea of Swords.

This article explores the eight foundational principles that govern how the Waterdeep Trading Company records, measures, and reports its financial activities. Each principle serves a specific purpose, and together they create a complete system of accountability that has earned the trust of merchants, nobles, and banking houses throughout Faerûn.

What Are Accounting Principles?

Accounting principles are the agreed-upon rules and standards that dictate how financial transactions are recorded and reported. They ensure that anyone reading the company’s ledgers, whether a guild auditor in Waterdeep or a trading partner in Luskan, can understand exactly what the numbers mean and trust their accuracy.

Without these principles, every scribe might record transactions differently. One might count inventory when it arrives at the warehouse, another when it is sold, and a third when payment is received. Such chaos would make it impossible to determine the company’s true financial position or to compare performance across seasons, locations, or product lines.

The Waterdeep Trading Company adheres to eight core principles that have been refined over centuries of trade practice throughout the Realms. These principles are recognized by the major guilds, accepted by tax collectors from the Lords of Waterdeep, and respected by investors and creditors alike.

The Eight Foundational Principles

Business Entity Principle: The Guild Stands Apart

The Business Entity Principle establishes that the Waterdeep Trading Company is a separate entity from its owners, investors, and officers. The personal wealth of Lord Merchant Harvin Stoneweather, the company’s founder, is not mixed with the company’s treasury. His private collection of Cormyrean wines, his estate in the Sea Ward, and his personal investments in shipping ventures are his own affairs.

This separation means that when the company borrows coin from the House of the Moon or extends credit to the Blacksmiths Guild of Baldur’s Gate, those obligations are the company’s alone. Personal transactions of owners, such as purchasing a noble title or funding a temple, are never recorded in the company’s ledgers.

This principle protects both the company and its owners. It allows the business to be evaluated on its own merits, makes succession planning clearer when ownership changes, and prevents creditors from seizing personal assets if the company faces hardship.

Money Measurement Principle: Only Coin Counts

The Money Measurement Principle states that only transactions that can be expressed in monetary terms are recorded in the accounting ledgers. The company measures everything in Faerûnian Standard Denomination, or FSD, which represents the common gold piece standard used across most civilized lands.

This means that many valuable aspects of the business are not recorded. The exceptional skill of Master Enchanter Talia Moonwhisper, the loyalty of veteran caravan guards, the company’s reputation among noble houses, and the secret trade routes discovered by explorers are all priceless assets. Yet they do not appear in the ledgers because they cannot be reliably measured in coin.

What gets recorded are purchases, sales, wages, rent, materials, debts, and any other transaction in which coin or credit changes hands. If a warehouse burns down, the loss is recorded at the value of the inventory and structure destroyed. If the company’s reputation suffers from a scandal, that intangible damage is not recorded, even though its effects may eventually show in reduced sales.

This principle keeps the ledgers objective and verifiable. Any two competent scribes should arrive at the same numbers when examining the same transactions.

Going Concern Principle: The Company Endures

The Going Concern Principle assumes that the Waterdeep Trading Company will continue operating for the foreseeable future. It is not on the verge of dissolution, will not be liquidating its assets next month, and plans to honor all long-term contracts and commitments.

This assumption affects how assets are valued. The company’s warehouse in the Dock Ward is recorded at its original cost, not at what it might fetch if sold tomorrow in a desperate auction. The enchanted scales in the counting house, the fleet of wagons, and the inventory of trade goods are all valued based on their continued use in the business, not their liquidation value.

If the company were winding down operations, everything would need to be revalued at fire sale prices. A set of fine merchant scales worth 150 FSD in normal operation might sell for only 80 FSD if the company needed to convert everything to coin within a tenday. The difference matters greatly to creditors and investors trying to understand the company’s true worth.

The key assumption of this principle is that the business will operate continuously. Assets like buildings, tools, and long-term contracts are valued assuming they will be used to generate future income, not sold off in distress.

Cost Principle: Original Value Holds

The Cost Principle requires that assets be recorded at their acquisition cost and generally be maintained at that cost in the ledgers. When the company purchased a building in the Trades Ward for 12,000 FSD three years ago, that amount was recorded in the accounts, even though the property could now sell for 18,000 FSD due to rising property values in Waterdeep.

This principle prevents the ledgers from becoming a battlefield of opinions about what things might be worth. Market values fluctuate based on rumors, seasonality, economic conditions, and numerous other factors. Recording assets at their original cost provides a stable, verifiable basis for accounting.

The purchase price is objective and supported by contracts, receipts, and witnesses. It represents what was actually paid, not what someone hopes or fears the asset might be worth today. This historical cost forms the basis for calculating depreciation, determining profit on eventual sale, and making management decisions.

The Cost Principle works hand in hand with the Going Concern Principle. Together, they prevent wild swings in reported asset values and keep the focus on actual business operations rather than speculation about what assets might sell for.

Matching Principle: Expenses Follow Revenue

The Matching Principle requires that expenses be recorded in the same accounting period as the revenue they helped generate. This ensures that profit calculations reflect the true cost of earning that income, not just the timing of bill payments.

Consider a caravan journey from Waterdeep to Baldur’s Gate that departs in the last week of Eleint and arrives in the first week of Marpenoth. The goods are sold immediately upon arrival. Under the Matching Principle, all expenses related to that journey, including caravan guard wages, wagon maintenance, provisions, and gate tolls, are recorded as expenses in Marpenoth when the revenue from sales is recognized, even if some of those costs were actually paid in Eleint.

This matching prevents distortion in monthly profit reports. Without it, Eleint might show a large loss from caravan expenses with no offsetting revenue, while Marpenoth would show enormous profit from sales with no associated costs. Neither picture would be accurate.

The Matching Principle helps management understand the true profitability of different operations and makes period-to-period comparisons meaningful. It shows the actual cost of generating each gold piece of revenue.

Accrual Principle: Timing by Event, Not by Coin

The Accrual Principle states that transactions are recorded when they occur, not when payment is exchanged. Revenue is recognized when earned, regardless of when the customer pays. Expenses are recorded when incurred, regardless of when the company settles the bill.

If the company delivers 200 barrels of Waterdhavian ale to the Elfsong Tavern in Baldur’s Gate on Uktar 15 under 30-day payment terms, the revenue is recorded on Uktar 15. That is when the company fulfilled its obligation and earned the coin, even though the actual gold pieces will not arrive until Nightal 15.

Similarly, if the company receives a shipment of iron ingots from the Ironmaster’s Guild on Flamerule 10 with payment due in 45 days, the expense is recorded on Flamerule 10. The company has received value and incurred an obligation, even though the coin will not leave the treasury until Eleasias 25.

The Accrual Principle provides a more accurate picture of business activity. It shows when economic value actually moved, not just when coin changes hands. This distinction is critical for understanding the company’s true financial position and performance during any given period.

Conservatism Principle: Caution in Uncertainty

The Conservatism Principle, also known as the Principle of Prudence, guides the company’s handling of uncertainty in its financial statements. The core rule is simple: anticipate no profits, but provide for all potential losses. When in doubt, choose the accounting treatment that is less likely to overstate assets or income.

If the company holds inventory of exotic spices that cost 3,000 FSD but market prices have fallen to 2,200 FSD, the inventory is written down to 2,200 FSD. The potential loss is recognized immediately. However, if those same spices now sell for 4,500 FSD due to a market shortage, the inventory remains recorded at the original cost of 3,000 FSD. The potential profit is not recognized until the spices are actually sold.

This principle protects creditors and investors from overly optimistic financial statements. It ensures that assets are not overstated and that the company is not presenting a rosier picture than reality supports. Better to be pleasantly surprised by hidden strength than shocked by concealed weakness.

The Conservatism Principle applies throughout the accounting process. When estimating bad debts from customers who may not pay, the company errs on the side of higher estimates. When judging whether a lawsuit might result in loss, provisions are made if loss is probable. This prudent approach builds credibility and trust in the company’s financial reports.

Dual Aspect Principle: The Balance of All Things

The Dual Aspect Principle is the foundation of double-entry bookkeeping and states that every transaction has two sides that must be recorded. Every action creates an equal and opposite reaction in the ledgers. This principle is expressed in the fundamental accounting equation that every apprentice scribe learns on their first day:

Assets = Liabilities + Capital

When the company purchases a wagon for 800 FSD in coin, two things happen simultaneously. Assets decrease by 800 FSD in coin and increase by 800 FSD in wagons. The accounting equation remains balanced because total assets have not changed, only their composition.

When the company borrows 5,000 FSD from the Temple of Waukeen, assets increase by 5,000 FSD in coin, and liabilities increase by 5,000 FSD in debt owed. Both sides of the equation increase by the same amount, so the balance is maintained.

This dual nature of transactions provides a built-in error check. If the two sides of any transaction are not equal, or if the accounting equation does not balance after all transactions are recorded, an error has occurred and must be identified and corrected.

The Dual Aspect Principle ensures that the ledgers tell a complete and accurate story. Every transaction is viewed from two perspectives, showing both where value came from and where it went. This creates a web of internal consistency that makes fraud more difficult and errors easier to detect.

How These Principles Work Together

The eight principles do not operate in isolation. They form an integrated system of rules that work together to create reliable financial information. The Business Entity Principle establishes what should be recorded, the Money Measurement Principle defines how it should be measured, and the Going Concern and Cost Principles provide the framework for valuing assets.

The Matching and Accrual Principles govern the timing of recognition, ensuring that financial results reflect economic reality rather than just the movement of coin. The Conservatism Principle adds a layer of prudence that protects against overstatement, while the Dual Aspect Principle provides the mathematical structure that holds everything together.

Consider a complete transaction cycle at the Waterdeep Trading Company. The business purchases enchanted armor from a smith in Neverwinter on credit, ships it to Baldur’s Gate by caravan, stores it in a warehouse, and eventually sells it to a mercenary company on delayed payment terms.

Every step of this process is governed by multiple principles working in concert. The Cost Principle values the armor at the purchase price. The Accrual Principle records the expense when the armor is received, not when the smith is paid. The Going Concern Principle assumes the assets will be held and used in normal business operations. The Matching Principle ensures warehouse costs and caravan expenses are recognized when the armor is sold. The Conservatism Principle may require recording the value if the armor becomes obsolete before sale. Throughout, the Dual Aspect Principle ensures that every transaction maintains the fundamental accounting equation.

This interplay of principles produces financial statements that outside parties can trust, management can use to make decisions, and auditors can verify. The result is a shared language of commerce understood throughout Faerûn.

Final Thoughts

The eight pillars of accounting principles are more than abstract rules written by guild accountants and tax collectors. They are practical tools that enable the Waterdeep Trading Company to manage complex operations across multiple cities, engage with hundreds of customers and suppliers, plan for the future, and demonstrate its reliability to anyone who reviews its books.

For apprentice scribes learning the trade, these principles provide clear guidance on handling the countless situations that arise when recording daily transactions. For managers and officers, ensuring consistent information is essential for making strategic decisions. For investors and creditors, they offer assurance that financial reports present a true and prudent picture of the company’s position.

Whether you are counting coins in a Waterdeep warehouse, negotiating contracts in the markets of Calimport, or reconciling accounts after a caravan’s return from distant Silverymoon, these principles guide every entry in the ledger. They are the foundation upon which trust and prosperity are built in the merchant houses of Faerûn.

Master these principles, and you master the language of commerce. Understand these principles, and you understand why the Waterdeep Trading Company has thrived for generations while lesser guilds have risen and fallen with the changing fortunes of the Realms.
