About FreeTierStack

FreeTierStack helps freelancers, solo founders and teams of 1–10 people run their business on free software tiers without nasty surprises. We cover invoicing, scheduling, CRM, email marketing, forms, project management and the other tools a small business needs.

How we research

• We check every free-plan limit against the vendor's own live pricing page and link to it.
• Each article shows the month we verified it. Free plans change often, so we re-check them on a schedule.
• We don't publish claims we couldn't verify. If a vendor's page is unclear, we say so.
• No vendor pays to be included or ranked. If we add affiliate links or sponsors later, we'll label them clearly.
