Foundational Skills for Accounting and Finance Professionals

In accounting and finance we spend a lot of time focusing on technical skills. We train people on advanced Excel techniques, technical accounting guidance, financial systems, and modeling tools. Those skills matter and they are part of what makes our profession specialized.

Lately I have been thinking more about another category of skills that often receives less attention but matters just as much early in a career. I tend to think of these as foundational skills. They apply almost everywhere in accounting and finance and they shape how effective someone becomes long before technical specialization begins to matter.

From both my work in the profession and my experience teaching accounting students in the evenings, I usually group these foundational skills into four areas. Excel and financial systems, accounting and financial knowledge, communication, and professionalism with accountability. Regardless of whether someone ends up in audit, corporate accounting, consulting, or FP&A, these four areas tend to show up again and again in day to day work.

One thing that has stood out to me over the years is that these skills are rarely the focus of formal training. Many organizations assume people will simply pick them up along the way. In reality, they often need to be developed intentionally.

Excel and Financial Systems

When people talk about Excel skills the conversation usually jumps to advanced formulas or automation. Those things are helpful, but the most important Excel skill is something much simpler. It is the ability to show your work clearly.

Anyone who reviews spreadsheets regularly has experienced the frustration of trying to understand a workbook that contains hard coded numbers with little explanation. When a reviewer has to open cell after cell just to understand where a number came from, the file becomes difficult to follow and even harder to maintain.

I often tell students and staff a simple rule. If I have to look inside your cell to see what you did, you have already lost.

A strong spreadsheet explains itself. Inputs are labeled, formulas reference other cells instead of hard coded numbers, and assumptions are documented so that someone reviewing the work can follow the logic without reverse engineering the file.

There are also a number of smaller habits that signal strong Excel fundamentals. Clear labels on input cells, identifying links to external data sources, and maintaining consistent file names and version control all make a file easier to review later. Keyboard shortcuts are another area that tends to correlate with overall proficiency. In my experience, people who work comfortably in Excel without relying heavily on the mouse usually have developed better habits in documentation and structure as well.

The biggest difference I often notice between my own work and the work of earlier career professionals is the level of preparation for review. I rarely build a file only for the current task. I usually assume that someone else will review it, revisit it, or potentially roll it forward in a future period. Taking that extra step when building a file makes a significant difference over time.

Accounting and Financial Knowledge

Foundational accounting knowledge is not about mastering the most complex areas of GAAP. It is about understanding how the accounting system actually functions.

Every accounting professional should be comfortable with the basic mechanics of debits and credits and know which accounts increase or decrease with each. They should understand how activity flows through the income statement and ultimately affects the balance sheet. They should also have a practical understanding of how the statement of cash flows connects to the rest of the financial statements.

In practice this knowledge becomes especially important because real accounting systems rarely behave as neatly as textbook problems. When students work through problems in class the numbers are curated and designed to illustrate a concept. In a real accounting system the numbers may be incomplete, inconsistent, or occasionally incorrect.

This is where what I often call a sanity check mindset becomes important. Accountants spend a large portion of their day looking at numbers in systems, and developing a sense for when something does not make sense is extremely valuable.

A simple example is seeing a negative bank balance in a general ledger. In some cases that may be completely reasonable, such as when outstanding checks are clearing through a zero balance sweep account. In other cases it could signal a more serious issue, such as entries being posted into prior periods and affecting balances for months without being noticed.

Understanding how journal entries affect the financial statements over time is also part of this foundation. Many early career professionals learn how to record entries but have not yet developed a framework for using journal entries to correct financial statements when problems appear. Building that understanding becomes increasingly valuable as responsibilities grow.

Communication

Communication is one of the most underestimated skills in accounting and finance. Students often assume it refers to presentations or public speaking, but most professional communication happens in smaller and more routine moments.

It shows up when explaining a variance to a manager, when summarizing the results of an analysis, or when asking questions about something that does not look right. Clear communication in these situations often reflects clear thinking about the underlying work.

One example I see regularly is how professionals approach problems with their manager. Bringing a problem without any research forces the manager to do all of the thinking. Bringing the same problem with two or three possible solutions creates a much more productive discussion and demonstrates ownership of the work.

Good communication habits also include listening carefully to instructions, taking notes, and confirming expectations when needed. Acting on feedback quickly and knowing when to ask for help are equally important. Some professionals hesitate to ask questions because they worry about sounding inexperienced, but waiting too long often creates larger issues later.

Another valuable skill is the ability to translate accounting concepts into plain English when speaking with people outside the accounting function. Many stakeholders in an organization do not work with financial statements every day, and the ability to explain financial information clearly can make a significant difference.

Professionalism and Accountability

Professionalism and accountability often determine how quickly someone progresses early in their career. These qualities are sometimes assumed rather than taught, but they shape how colleagues and managers experience working with someone.

One of the strongest signals of professionalism is the willingness to ask small questions early. Many early career professionals worry about appearing inexperienced, but asking a quick question often prevents hours of unnecessary work later.

Another signal is thinking about the completion of the work rather than focusing only on individual tasks. Professionals who naturally think about the broader objective of a project tend to collaborate more effectively and support their teams when additional help is needed.

The opposite patterns are usually easy to recognize as well. Some professionals communicate very little and quietly struggle with assignments instead of asking for clarification. Others focus only on the tasks directly assigned to them and show little interest in helping teammates when additional work appears.

These behaviors may seem small, but they shape how reliable someone appears to others in the organization.

Teaching and Practice Reinforce the Same Lesson

These foundational habits appear clearly in both the classroom and the workplace.

Every semester when I teach accounting I see students submit homework that technically answers the question but is extremely difficult for anyone else to follow. Numbers are placed on the page with little structure, assumptions are not labeled, and the reasoning behind the work is not documented. At some point each semester I pause and explain why formatting and documentation matter. Accounting work is not just about arriving at the correct answer. It is also about presenting the work in a way that someone else can understand and review later.

The same principle shows up in professional practice. When I worked in audit there was a simple philosophy that guided documentation. If it was not documented, it did not happen. Auditors assume nothing.

Over the years there were multiple situations where a staff member had a conversation that explained a balance or resolved a question, but the explanation never made it into the workpaper documentation. When the file was reviewed later the same question appeared again because the supporting explanation was missing.

The work itself may have been completed, but without documentation the evidence was not there.

Technical knowledge will always matter in accounting and finance, but foundational habits determine how effectively that knowledge is used. Professionals who build strong habits in documentation, financial understanding, communication, and accountability tend to stand out quickly.

The encouraging part is that these are not innate traits. They are professional habits that can be developed intentionally. For students and early career professionals, investing time in these foundations early tends to make every technical skill learned later much more valuable.
