Copying to an existing company is usually faster. It carries over chart of accounts, posting groups, dimensions, and setup rules. A blank company is better only if your accounting structure is completely different, or you want a clean rebuild.

Yes. Business Central excels imports and data migration tools for systems like QuickBooks and legacy ERPs. Master data (customers, vendors, items) is usually migrated first, followed by opening balances and historical transactions if required.

Yes. Posting groups are company specific. If you copy an existing company, they come across it automatically. If you create a blank company, posting groups must be set up manually before transactions can be posted.

Use Sandbox for testing, training, and configuration validation. Once everything is confirmed, replicate the setup in Production to avoid data or posting errors.

Yes. Trials allow multiple companies, but all data is deleted once the trial expires unless you convert to a paid subscription.

Yes. Business Central allows consistency across environments (Sandbox, Test, and Production) by using tools such as Copy Company, Configuration Packages, and RapidStart templates. These tools help replicate chart of accounts, posting groups, dimensions, number series, and other core setups. Maintaining shared setup logic across environments ensures predictable behavior, reduces configuration drift, and simplifies testing before production deployment.

Company setup plays a critical role in consolidation and intercompany processes. Consistent charts of accounts, dimensions, fiscal calendars, and posting groups across entities significantly reduce reconciliation effort during consolidation. Proper initial setup also ensures smoother intercompany transactions, accurate elimination of entries, and reliable group-level financial reporting. Poor alignment at the setup stage often leads to manual adjustments, reporting inconsistencies, and increased audit risk later.
