What is Bookkeeping in Business?

Bookkeeping is the process of recording all the financial transactions of a business in an organised way.

Every time a solar PV business buys materials, pays for transport, installs a solar panel, or receives money from a customer, it is a financial transaction. Bookkeeping involves writing down these details carefully so that the business knows exactly how much money it has, how much it owes, and how much it is owed.

For a solar PV installation and maintenance business, keeping good records helps track the cost of solar panels, batteries, inverters, and the money received for installation services or repairs. It is like keeping a financial diary for the business.

Sources of Primary Book of Entries

Primary book of entries refers to the first place where business transactions are recorded. These are the original documents that provide evidence of a transaction. They are very important because they show exactly what happened, when it happened, and how much money was involved.

Common sources of primary book of entries for a solar PV business include:

1. Receipts: A receipt is a written acknowledgement that a sum of money has been received. When a solar PV business sells a solar panel or completes an installation, it gives a receipt to the customer. When the business buys materials like wires or tools, it receives a receipt from the supplier.
2. Payment Vouchers: A voucher is a document used to authorise a payment. It shows that money was paid for a specific purpose, such as paying a technician’s daily wage or buying fuel for a service vehicle.
3. Invoices: An invoice is a bill sent by a seller to a buyer, requesting payment for goods or services. A solar PV business might send an invoice to a customer after installing a system, detailing the cost of parts and labour.
4. Bank Statements: These are records from the bank showing all money deposited into and withdrawn from the business’s bank account.
5. Cheque Stubs: The part of a cheque book that remains after a cheque has been written and detached. It contains a record of the cheque number, date, payee, and amount.
6. Sales Slips: Similar to receipts, these are records of sales made, often generated by cash registers or point-of-sale systems.

These documents are the first step in bookkeeping. They provide the raw information that is later organised into ledgers and other financial records.

Types and Methods of Bookkeeping

Bookkeeping can be done in different ways, depending on the size and nature of the business. For a JSS1 student, it is important to understand the two main approaches:

1. Manual Bookkeeping: This method involves recording transactions by hand in physical books or ledgers. Many small businesses, including some solar PV installation and maintenance businesses, start with manual bookkeeping. It requires careful writing and organisation of documents like receipts and vouchers into record books.
2. Computerised Bookkeeping: This method uses computer software or spreadsheets to record and manage financial transactions. It is faster, more accurate, and can automatically calculate totals and generate reports. Many modern solar PV businesses use computerised systems, even simple spreadsheet programs, to keep their records.

Regardless of the method used, the goal is always the same: to keep accurate and organised records of all money coming into and going out of the business.

Benefits of Bookkeeping

Bookkeeping offers many important benefits to a solar PV business, its owners, and its customers.

Benefits to the Enterprise (The Business Itself)

1. Tracks Money: Bookkeeping helps the solar PV business know exactly how much money it has, how much it has spent, and where the money went. This helps in managing cash flow.
2. Measures Performance: By looking at the records, the business can see if it is making a profit or a loss. It can identify which services (like installation or maintenance) are most profitable.
3. Helps with Planning: Good records help the business plan for the future, such as deciding if it can afford to buy new tools or hire more technicians.
4. Legal Compliance: Businesses are often required by law to keep financial records for tax purposes and other regulations.

Benefits to Business Owners

1. Informed Decision-Making: Owners can make better decisions about their solar PV business when they have clear financial information. For example, they can decide whether to expand services or adjust prices.
2. Financial Control: Bookkeeping gives owners control over their money. They can easily see if there are any unusual expenses or if money is being wasted.
3. Access to Loans: If a business owner needs a loan to grow their solar PV business, banks will usually ask for financial records to assess the business’s health.
4. Peace of Mind: Knowing that all financial matters are in order can reduce stress for the business owner.

Benefits to Customers

1. Proof of Payment: Customers receive receipts for their payments, which serve as proof that they have paid for solar PV products or services. This is important for their own records.
2. Warranty Records: Bookkeeping helps the business keep track of sales, which is crucial for honouring product warranties (e.g., for solar panels or inverters). If a customer has an issue, the business can easily verify their purchase.
3. Accurate Billing: Good bookkeeping ensures that customers are billed correctly for the services they receive, preventing overcharges or disputes.
4. Trust and Reliability: A business that keeps good records appears more professional and trustworthy to its customers.

Recording Transactions in Documents

Keeping records is a practical skill that involves carefully writing down details of financial transactions. This helps to ensure that all money movements are tracked accurately.

How to Record a Transaction Using a Receipt or Voucher

This procedure explains how to record a simple transaction using common documents like receipts or vouchers. Imagine a solar PV business buying new tools or receiving payment for an installation.

The required materials are:

1. A blank receipt book or payment voucher forms.
2. A pen.
3. A calculator (optional, for checking totals).

The procedure involves the following steps:

1. Identify the Transaction: Determine what happened. Was money received (e.g., from a customer for installation) or paid out (e.g., for buying solar panel cables)?
2. Choose the Correct Document:
   1. If money was received, use a receipt.
   2. If money was paid out, use a payment voucher.
3. Fill in the Date: Write the exact date of the transaction at the top of the document.
4. Identify the Parties:
   1. For a Receipt: Write the name of the person or company who paid the money (the customer).
   2. For a Payment Voucher: Write the name of the person or company who received the money (the supplier or employee).
5. Describe the Transaction: Clearly state what the money was for.
   1. For a Receipt: “Payment for solar panel installation at Mr. Bala’s house.” or “Purchase of 200W solar panel.”
   2. For a Payment Voucher: “Payment for transport of tools to site.” or “Purchase of electrical wires.”
6. Write the Amount in Figures: Write the amount of money involved using numbers (e.g., N5,000.00).
7. Write the Amount in Words: Write the amount of money in words to prevent alteration (e.g., “Five Thousand Naira Only”).
8. Sign and Stamp: The person receiving or making the payment should sign the document. If the business has an official stamp, it should be stamped.
9. Keep a Copy: Always ensure a copy of the receipt or voucher is kept for the business’s records. For receipt books, this is usually a carbon copy.

By following these steps, a solar PV business can keep clear and accurate records of all its financial activities.
