A hundred years ago, every transaction was written by hand into paper journals and ledgers. Today, almost every business uses some form of computerized accounting system. Technology has made accounting faster, more accurate, and more connected — but it hasn't replaced the need to understand what's actually happening underneath the software, because someone still has to decide what to record and verify that it's correct.
From Paper to Computer
Even in a computerized system, someone needs to organize the raw information before it's entered. A data entry sheet is used to organize the information to be entered into a computerized accounting system — it lists the accounts to be debited and credited, the amount, and an explanation of the transaction, exactly like a journal entry, before it's typed into the software.
Cloud Accounting
Modern accounting software often runs "in the cloud" rather than on one office computer: the data lives on remote servers and can be accessed securely from anywhere with an internet connection. This lets a bookkeeper, the owner, and an external accountant all view the same live numbers at once, and it means data is automatically backed up instead of living on a single hard drive that could fail.
Point-of-Sale Systems and Electronic Payments
- A point-of-sale (POS) terminal is an electronic cash register linked to a computer — it records the sale, calculates HST, updates inventory, and sends the transaction straight into the accounting system, all in one step.
- Debit cards are a method of transferring funds between two parties electronically, moving money directly out of the customer's bank account at the moment of sale.
- Electronic funds transfer (EFT) is a cash exchange system where bank accounts are accessed electronically over a secure network — used for things like direct-deposit payroll or paying a supplier without writing a cheque.
- Spreadsheet software (like Excel or Google Sheets) is often used for budgets, quick calculations, and analysis that sits alongside the main accounting system.
