The Sourdough Store review for Quaderno: Taxes & E‑Invoicing

Jan. 17, 2026

I’ve been using Quaderno for over four years, and it has become the central hub for my accounting and tax reporting. I sell online courses and physical merchandise internationally through Shopify as well as other platforms, so having everything tied together in one system is essential. Quaderno handles currency conversions, international VAT obligations, invoicing, and reporting in one place, which allows me to see clear, accurate figures across the entire business, including P&L reporting. There is no local accounting software available in Greece that comes close to offering this level of international tax compliance and automation. Quaderno removes the stress of dealing with complex international tax rules and keeps everything clean, consistent, and well organised. On the rare occasions I’ve needed support, their team has been fast, clear, and genuinely helpful. I honestly couldn’t run my business without it.
