What accounting software do large companies and big businesses use?

SAP S/4HANA and Oracle Financials are the giants of enterprise accounting. They handle everything from general ledger to supply chain, HR, and global compliance. They are expensive - implementations often cost hundreds of thousands of dollars - and require dedicated IT teams.

Microsoft Dynamics 365 Finance is another large-company choice, particularly popular with businesses already deep in the Microsoft ecosystem. It integrates tightly with Excel, Teams, and Power BI, which makes it attractive for organizations that have standardized on Microsoft tools. All three platforms require long implementation timelines - typically six months to two years for a full deployment.

NetSuite by Oracle sits between enterprise and small business - it is cloud-based, scales to hundreds of users, and handles multi-entity consolidation. Sage Intacct is another strong mid-market choice, especially for companies that need dimensional reporting.

Both typically cost $1,000–$5,000+ per month depending on modules and users. Implementation fees add significantly to the first-year cost. For businesses at this stage, the investment is usually justified - the reporting depth and automation they provide saves finance team hours each month and reduces the risk of reporting errors.

Most businesses do not need enterprise software until they have a dedicated finance team, multiple legal entities, or complex revenue recognition requirements. Note.now handles most growing businesses up through the mid-market stage and can export clean data when and if you ever need to move to a larger platform.

The clearest sign you need to upgrade is when your finance team is spending significant time working around your accounting software rather than in it. If you are maintaining parallel spreadsheets because the software cannot produce the report you need, or manually eliminating intercompany transactions each month, you have outgrown your current tool.
