Accounting and bookkeeping basics: What you need to know for your startup

Bookkeeping is the process of recording, organizing, and managing a company's financial transactions daily. Among the many tasks are documenting income, expenses, sales, and purchases systematically and accurately.

For startups—no matter your industry—proper bookkeeping is vital. It’s important from day one, as soon as you secure initial capital. That’s because effective bookkeeping helps ensure correct fund management and financial transaction recording. It also provides clear visibility into your cash flow and expenses and prepares you for those all-important tax obligations. Plus, when you’re confident about your financial health, you can showcase that to investors and stakeholders, attracting even more resources to bring your innovative ideas to life.

Why accounting matters for startups

While accounting is crucial for keeping your finances in order, there’s more big-picture value to it. Here’s why solid accounting practices are so important:

• Cash flow management: Keeping precise records of every transaction helps you understand how cash moves in and out of your business. This insight is key to maintaining liquidity, covering operational expenses, and avoiding unexpected shortages.
• Informed decision-making: Having accurate, up-to-date financial data helps you analyze trends in performance, spot strengths and weaknesses, and make smart decisions about budgeting and investments.
• Attract investors: Investors want to see a transparent and organized financial record. When your books are in order, it builds trust and shows that your startup is a reliable, promising investment.
• Ensure tax compliance: Proper accounting makes it easier to stay compliant with tax laws and avoid penalties because you have organized records that allow you to file accurately and on time.
• Prepare for growth: As your startup scales, an organized accounting system gives you the detailed financial insights you need to allocate resources effectively, manage risks, and seize new opportunities.

Accounting vs. bookkeeping: What's the difference?

While "bookkeeping" and "accounting" are often used interchangeably, their functions differ. Think of a bookkeeper as a nurse who carefully monitors a patient’s daily vital signs and tracks every detail like temperature, blood pressure, and heart rate. On the other hand, an accountant is like a doctor who reviews these records to diagnose the patient’s overall health, develop a treatment plan, and provide insights for long-term well-being.

Let’s look at what these roles bring to the table and how they work together to keep your business financially fit.

Bookkeeping

Bookkeeping primarily focuses on the day-to-day recording and organization of financial transactions. A bookkeeper will be responsible for:

• The daily recording of transactions (sales, purchases, payments, etc.)
• Posting debits and credits to the general ledger
• Reconciling bank statements with accounting records
• Managing accounts payable and receivable
• Preparing invoices and processing payments
• Running basic financial statements (e.g., income statement, balance sheet)
• Processing payroll and maintaining employee records

Accounting

Accounting involves analyzing and interpreting financial data. An accountant will provide insights that drive strategy and uphold a business’s compliance with tax laws and other financial regulations. The role of an accountant entails:

• Reviewing and assessing financial statements to identify trends and anomalies
• Preparing and adjusting journal entries to ensure financial record accuracy
• Conducting internal and/or external audits to verify regulation compliance 
• Preparing and filing tax returns
• Giving financial advice 
• Financial strategizing and forecasting

How to set up accounting and bookkeeping for your startup

Getting your accounting and bookkeeping in order from the start will save you time, stress, and potential financial headaches down the road. Here’s a step-by-step guide to setting up and managing your startup’s finances.

Step 1. Open a business bank account

Keeping your personal and business finances separate is a must. A dedicated business bank account makes it easier to track expenses, manage cash flow, and prepare for tax season without any confusion.

Step 2. Choose an accounting method

There are two main ways to track your finances: Cash and accrual basis accounting.

• Cash basis accounting: You record transactions when money actually moves in or out.
• Accrual accounting: You record transactions when they happen, even if the money hasn’t changed hands yet.

Accrual accounting is generally considered the preferred method for startups as it provides a more accurate picture of financial health by recognizing revenue and expenses when they occur, not just when cash changes hands.

Go to the section “Accounting methods: Cash vs. accrual” for more information and decide which accounting method is best for your startup.

Step 3. Choose an accounting system

Many startups choose cloud-based accounting software like QuickBooks Online to manage their finances from day one. These platforms are popular for their affordability, ease of use, scalability, and real-time access to financial data from anywhere. If you prefer something simpler, a well-organized spreadsheet can work when you’re just starting out.

Step 4. Track every transaction

To ensure reliable financial statements, consistently log your financial activity, including:

• Income from sales, services, or investments.
• Business expenses like rent, utilities, and marketing.
• Payroll costs for employees and contractors.

It’s also a good idea to set aside time weekly or monthly to update your records to avoid last-minute scrambles.

Step 5. Monitor your cash flow

Cash flow is the lifeblood of your business, so keep an eye on how much money is coming in versus going out so you can plan ahead. Unexpected expenses happen, and staying on top of your finances helps you avoid running into cash shortages.

Step 6. Decide between DIY or outsourcing

If bookkeeping feels overwhelming or time-consuming, hiring a bookkeeper or accountant can free you up to focus on growing your business. There are also virtual bookkeeping services like Quickbooks Live that handle everything for you at an affordable price.

On the other hand, If you’re comfortable with numbers and using accounting software, you can manage your books yourself. This gives you more control and saves money.

Key bookkeeping tasks

Wondering how to do basic bookkeeping for your small business? To keep your startup financially healthy, getting a handle on your bookkeeping is a must. Here’s a breakdown of common tasks you’ll need to manage:

Track and analyze financial transactions

Up-to-date records are essential for accurate financial reporting and decision-making. A bookkeeper should record sales revenue (income), bills and operating costs (expenses), equipment and property (assets), and loans and debts (liabilities). Specific records include sales receipts, purchase invoices, bank statements, and expense reports. 

Transaction recording methods: This task can be managed manually or by using automated accounting software, like QuickBooks, which streamlines the task and helps minimize errors.

Reconcile accounts

Account reconciliation means comparing your bank account balance with your ledger's cash balance to confirm they match. Reconciling your accounts helps spot discrepancies, prevent fraud, and keep your financial records accurate. 

Account reconciliation is typically done on a daily or monthly basis. Businesses with higher transaction volumes, such as restaurants, commonly reconcile accounts daily. 

Manage accounts payable

Managing accounts payable (AP) involves handling unpaid bills to suppliers, vendors, and creditors. Startups sometimes find this somewhat challenging due to limited resources, lack of experience, cash flow constraints, and rapid growth. Yet effective management of the following AP tasks is essential for financial stability.

• Invoice processing: Receiving, verifying, and recording invoices from vendors accurately and efficiently.
• Payment authorization: Establishing approval workflows and ensuring that invoices are reviewed and approved by appropriate stakeholders before payments are made.
• Payment execution: Scheduling and executing payments on time to avoid late fees and maintain positive vendor relationships.
• Recordkeeping: Maintaining accurate and up-to-date records of all invoices, payments, and vendor information for financial reporting and compliance.
• Vendor management: Building and nurturing strong relationships with vendors to negotiate favorable terms, ensure timely delivery of goods and services, and resolve any issues.

A professional bookkeeper, equipped with robust accounting software, can streamline these AP responsibilities, ensuring timely payments, accurate recordkeeping, and fostering positive vendor relationships.

Organize invoices 

Bookkeepers should monitor invoices, ensuring they're sent out promptly and following up if there are any payment delays. Efficient invoice management helps maintain healthy cash flow, which is vital for covering essential operational expenses and investing in growth opportunities.  

Digital storage and organization

Invoices are also essential documents required for taxes and compliance. Consider the benefits of digitally storing your tax-related documents. This storage method not only saves physical space but also helps keep them secure and ensures easy access and organization. Here's a step-by-step guide to help you:

Step 1: Organize and name your folders

Create a clear folder structure for each tax year (e.g., "2024 Taxes"). Within each folder, create subfolders for different categories like income, expenses, deductions, etc. Name your files descriptively (e.g., "W2_2023_JohnDoe.pdf") for easy retrieval.

Step 2: Save documents as PDFs

Convert all your tax documents into PDF format, which helps provide compatibility across different devices and prevents accidental changes to the original files.

Step 3: Choose a secure storage method

You could use a cloud storage provider or consider QuickBooks Online, which offers a secure document storage feature. Always protect your files with strong passwords or encryption.

Step 4: Maintain backups

Create multiple backups of your digital tax records. Store them on different devices or cloud services to safeguard against data loss.

Step 5: Practice document management

Regularly review and update your digital files. Delete unnecessary documents and ensure your folder structure remains organized.

Accounting methods: Cash vs. accrual

Before recording transactions, you must choose one of these two common accounting methods: Cash basis or accrual accounting.

Cash basis

Cash basis accounting is the simpler option. You record income only when you receive payment and log expenses only when you pay for something. This method makes it easy to see exactly how much cash you have at any given time, which is a great fit for early-stage startups with straightforward transactions. It’s also easier to manage without deep accounting expertise. However, since it doesn’t account for unpaid invoices or future expenses, it may not always reflect your business’s full financial picture.

Accrual

Accrual accounting tracks income and expenses as they’re earned or incurred, even if the money hasn’t changed hands yet. This gives you a more accurate view of your startup’s financial health, which is helpful when making long-term decisions, attracting investors, or applying for loans. Accrual accounting aligns with Generally Accepted Accounting Principles (GAAP) and is usually required as businesses grow. However, it’s more complex and requires more effort to track outstanding invoices and expenses.

Choosing the right method

So, which method should you choose? It depends on your business model, growth plans, and financial complexity. Cash basis is simple and great for managing day-to-day cash flow, while accrual gives you a clearer picture of your overall finances, especially as you grow.

Since this decision affects everything from taxes to financial reporting, it’s best to talk to an accountant or financial expert before making a choice. A professional can help you find the best method for your financial goals, tax needs, and what investors expect. They can also make sure you follow accounting standards so you can prevent costly mistakes down the road.

The financial records needed for every startup

Maintaining the following documents will keep your startup's finances on track and keep it in the good graces of the tax authorities.

Income statement (Profit and Loss statement)

Summarizes revenues, expenses, and profits over a specific period. It's a snapshot of your startup's profitability and operational efficiency.

Balance sheet

Details your assets (what you own), liabilities (what you owe), and equity (your investment) at a specific point in time. It reveals your financial position and net worth.

Cash flow statement

Tracks the flow of cash into and out of the business, highlighting your liquidity and ability to meet financial obligations.

Bank statements

Records of all transactions made through your business bank accounts, including deposits, withdrawals, and fees.

Invoices

Detailed records of goods sold or services rendered, including customer information, payment terms, and amounts owed.

Receipts

Proof of purchase for expenses incurred by the business, such as office supplies, inventory, and travel costs.

Payroll records

Documentation of employee wages, hours worked, taxes withheld, and benefits provided.

Tax returns

Copies of filed tax returns, including federal, state, and local income taxes, sales taxes, and payroll taxes.

Legal documents

Articles of incorporation, operating agreements, contracts, permits, and relevant business licenses.

Your business should also keep the following:

• Expense reports: Itemized lists of business expenses incurred by employees.
• Petty cash log: A record of small cash disbursements for miscellaneous expenses.
• Inventory records: Documentation tracking the quantity and value of inventory on hand.
• Accounts payable and receivable ledgers: A summary of money owed to suppliers and to the business by customers.
• Loan documents: Loan agreements, promissory notes, and amortization schedules for any outstanding loans.

Prepare and analyze financial statements

Organizing, preparing, and reporting financial statements—it's not just about numbers on a page. It's about empowering you and your team to make smart business choices and thrive. By understanding your income, expenses, assets, liabilities, and cash flow, you can:

• Plan for the future: Knowing exactly where your money comes from and where it goes helps you devise profit-boosting strategies, explore new markets, and invest in growth.
• Spot opportunities (and problems): Financial statements highlight your strengths and weaknesses. They can help you uncover untapped potential or catch minor issues before they transform into major problems. Leverage this data to avoid surprises, anticipate challenges, and prepare for the unexpected.
• Attract investors: If you're looking for funding, investors want to see the facts. Accurate financial documents build trust and show them your business is a wise opportunity.
• Keep the cash flowing: You need to know where your money is at all times. Correct numbers reveal how much you're earning and spending and whether you have enough to keep your operation running.

Bookkeeping strategies for startups

Having a solid game plan for your bookkeeping will save you time and keep your business financially healthy. Here are some key bookkeeping strategies to help you stay organized and efficient:

• Pick the right accounting software: The right bookkeeping tool can save you time and reduce errors. Software like QuickBooks helps you track expenses, send invoices, and generate reports—all in one place. Explore your options and choose a platform that fits your business needs and makes financial management easier.
• Automate wherever possible: Automate routine tasks—e.g., invoicing, payment reminders, and bank reconciliations to help reduce errors and free up time to focus on growing your business.
• Track every expense: Log all business expenses, from office supplies to software subscriptions. Consider using expense-tracking apps or linking your business account to accounting software so you don’t miss deductible expenses.
• Review financial statements regularly: Set aside time weekly or monthly to review key financial reports like profit and loss statements, balance sheets, and cash flow statements. This helps you spot trends, catch errors, and make informed decisions.
• Get professional help when needed: If bookkeeping starts to feel challenging, don’t be afraid to ask for help. A bookkeeper or accountant can make sure everything is accurate, help you stay compliant with tax laws, and offer financial advice as your business grows. Even occasional check-ins with a professional can save you time and prevent costly mistakes.

Common bookkeeping challenges 

As a startup founder, you're likely juggling multiple roles and responsibilities. Amid the excitement of building your product or service and growing your customer base, bookkeeping might not be at the top of your priority list. However, maintaining accurate financial records is essential for your venture's long-term success and stability. Let's explore some common bookkeeping hurdles businesses face and strategies to overcome them.

Recordkeeping headaches

For many new entrepreneurs, establishing a robust recordkeeping system can be overwhelming. With limited resources and time, putting off organizing financial documents or relying on makeshift solutions is tempting. How do you get your recordkeeping on the optimal track? Try these tips:

• Implement a digital filing system for all financial documents from day one
• Regularly update your records, ideally every week
• Consider using cloud-based storage for easy access and backup

Tax compliance confusion

Tax regulations are ever-changing and can be complex, especially for companies operating in multiple jurisdictions, regulated industries, or with novel business models. Failing to meet tax obligations can result in penalties and hinder your company's growth. Here are ways to facilitate compliance:

• Research tax requirements specific to your industry and business structure
• Set tax deadline reminders 
• Consider working with a tax professional experienced in startup matters
• Use software, like QuickBooks, that automates sales tax calculations, integrates with tax preparation software, generates tax reports, and sends deadline reminders

Cash flow management

Monitoring cash flow is essential for any business. Here are some bookkeeping tips to help you stay on top of it:

• Record every income and expense
• Classify expenses for better analysis
• Compare records with bank statements regularly
• Utilize software and employ automation tools like accounting software
• Analyze your data to identify trends and make informed decisions

Stressful spreadsheets

While spreadsheets might seem like a cost-effective solution for early-stage startups, they can quickly become inadequate, cumbersome, and messy as your business grows. Innovative accounting software offers features tailored to the needs of growing companies, such as:

• Integration with other business tools (e.g., CRM, project management software)
• Automated bank reconciliation and expense categorization
• Custom reporting for investor updates and financial analysis

Underutilized software 

Even when entrepreneurs invest in accounting software, they often underutilize its capabilities. This can lead to inefficiencies and missed opportunities for financial insights. To get the most out of your accounting tools, you or your bookkeeping and accounting teams should:

• Take time to explore all the software’s features and use cases
• Take advantage of the software provider's educational resources, including guides and videos
• Regularly review and update your processes to leverage new features

Missing out on tax deductions

Missing out on valuable tax deductions can be costly. To avoid this:

• Partner with a bookkeeper who can identify eligible deductions so you can leverage all opportunities to save on taxes. They will keep you updated on relevant tax changes and laws.
• Maintain meticulous records to ensure you have the necessary documentation to support your deductions. Leverage tools like QuickBooks to simplify recordkeeping and automatically categorize tax-deductible expenses.

Finding the right bookkeeping support

You might wonder: Do startups need a bookkeeper? While not strictly necessary in the early stages, hiring a bookkeeper or outsourcing to a virtual bookkeeper can save time, reduce errors, and provide valuable financial insights as your startup grows. Let’s break down the differences.

Hiring an in-house bookkeeper

An in-house bookkeeper works directly with you and your team, providing immediate assistance and a personal touch. However, having someone onsite does come at a cost. Typically, hiring an in-house bookkeeper can be expensive due to salaries, benefits, and office space requirements.

Outsourcing to a virtual bookkeeper

A virtual bookkeeper offers flexibility, working remotely and often on an as-needed basis, which can save you money. Communication and document sharing rely on digital tools.

But convenience doesn’t sacrifice expertise. Virtual bookkeepers often have experience with a variety of businesses and can bring a wealth of knowledge to your startup. They may also have bachelor's degrees in fields like business, as well as certifications from the American Institute of Professional Bookkeepers (AIPB), the National Association of Certified Public Bookkeepers (NACPB), or the Intuit Academy.

Whether you prefer onsite or virtual bookkeeping, confirm your bookkeeper has a strong understanding of financial principles, accounting software, and relevant tax regulations. They should also have experience recording transactions, managing accounts, and generating financial reports, preferably in your industry.

Take your startup to the next level with professional virtual bookkeeping 

From pitching investors to managing product development, you’ve got a lot of things on your plate. Everyday bookkeeping tasks don’t have to be one of them.
