From the abacus to written ledgers to adding machines and calculators, people have been using accounting tools for centuries.
Most businesses start off by relying on spreadsheets to manage the books, and many continue to use spreadsheets, even as the business grows and becomes more complex.
The result is disparate data spread across multiple spreadsheets that are often out of date or present conflicting numbers.
Businesses need to invest in modern accounting software solutions:
- Consolidate the financial data of a business in one place.
- Automate accounting processes like invoicing, accounts payable, accounts receivable, income and expenses.
- Make it much easier to disseminate financial data to both internal and external stakeholders.
With all financial data in a single place, accounting staff won't have to spend hours cross-posting information, re-keying numbers, or manually reconciling data. Ultimately, this saves a business time, reduces costs, and ensures more accurate financial reporting.
