Financial And Corporate Records Keep Startups Prepared: Startups should preserve financial statements, invoices, bank records, payroll documents, tax filings, board resolutions and shareholder approvals. These records help demonstrate how the company managed its finances and made important corporate decisions. Record-keeping requirements vary by jurisdiction, so founders should follow the rules that apply to their business. Keeping these documents organised can also prepare the startup for fundraising, audits, tax reviews or a potential acquisition.
