Restaurant is a 24-hour operation with long hours, erratic customer flow, a lot of competition and low profit. However, amidst the hustle of managing staff, suppliers and satisfying the customers, one important aspect that is usually overlooked is accounting.
Most restaurant owners often overlook the intricacies of financial record maintenance by believing that a general accounting software could be used or that it would be possible to do it themselves. Nevertheless, when the accounts for restaurants have not been properly banked, the journal entries can easily run amok, causing severe financial problems.
This blog will discuss the most typical errors of the restaurant businesses that register mistakes in their accounting and journal entries, and how to eliminate expensive errors and guarantee long-term profitability by employing specialised restaurant accountants.
Mistake #1: Not Regularly Managing Accounting Functions
The Problem:
Most of the restaurant owners can postpone the bookkeeping chores by just awaiting the next date or the month end; some can even wait up to the quarter ending.
The Impact:
- Time lapses in identifying financial red flags (e.g., cash flow deficiency, cost escalations)
- False financial shots
- Miscalculation of taxes or the missing tax deadlines
The Fix:
- Establish a weekly or bi-weekly bookkeeping schedule.
- Automate recurring journal entries (e.g., rent, subscriptions).
- Hire restaurant accountants to monitor day-to-day finances and issue timely reports.
Mistake #2: Not Using Restaurant-Specific Purchasing Software
The Problem:
Managing purchases by using Excel spreadsheets or non-restaurant software.
The Impact:
- Entry errors caused by manual inputs
- Late payments or vendor invoices
- Failure to correctly track the cost of goods sold (COGS)
The Fix:
- Install specific systems (MarketMan or SimpleOrder) used in restaurants.
- Software should be selected that is integrated with the accounting system.
- Follow purchases in real-time, which are even connected to the inventory and financial data.
Mistake #3: Improper Posting of POS Transactions and Expenses
The Problem:
Wrongly posting Point-of-Sale (POS) data, or failure to post it daily.
The Impact:
- Tips are not included in income
- Refunds and discounts left out
- Distorted sales numbers
The Fix:
- Use a POS system that integrates with accounting software (e.g., Square + Xero).

Mistake #4: Operating Without a Budget
The Problem:
There is no planned budget laid down as a guide on spending and revenue targets.

Mistake #8: Using a Generic Chart of Accounts
The Problem:
Applying a generic chart of accounts developed by use of a general business setup.
The Impact:

- Failure in detecting high-cost zones or menu profitability
The Fix:
- Prepare a customised chart of accounts that pertains to the restaurant business.
- Distinct sources of revenues (dine-in, takeaway, catering).
- Create spending into categories like food, drink, wages, waste, power, etc.
Mistake #9: Relying on the Wrong Accounting Method
The Problem:

The Impact:

- Misleading profitability
- Unsuccessful financial projection
The Fix:
- Convert to the accrual accounting method in recording income as earned and expenses as incurred.
- It gives a better financial representation.
- Hire professional restaurant accountants to help in the transition.
