Self-Hosted Accounting Software for Small Business

Your accounting data is among the most sensitive information your business holds. Revenue figures, client payment details, tax calculations, and profit margins are exactly the kind of data you want on your own infrastructure, not on a SaaS provider's servers. Self-hosted accounting software gives you full financial control.
