The bookkeeping services of an IT company must track and record numerous expenses and income streams. Employee salaries and benefits, software licences and subscriptions, hardware purchases and maintenance, marketing and advertising costs, rent and utilities, professional services, and travel expenses are all common expenses. Revenue sources may include software sales, consulting services, project-based contracts, maintenance and support agreements, and royalties or licencing fees. Accurate and comprehensive tracking of these expenses and income sources ensures effective financial reporting, budgeting, and tax compliance.
