Frequently Asked Questions

Are these tools free?+
Yes. Every tool on this page is free and requires no account.
Do I need to be a Gruv customer?+
No. Every tool works standalone. If you later adopt Gruv, the same concepts (invoicing, compliance gates, payouts, reconciliation) plug directly into a live workflow.
Is my data private?+
Most tools run entirely in your browser and store drafts on your device. When a tool calls an external service (for example, VAT validation via VIES), it says so on the page.
How do these tools connect to the Gruv platform?+
They answer the same questions Gruv automates: pricing, compliance, residency, documentation, and payout planning. Use a tool to get the answer, then use Gruv to operationalize it.
Is this tax, legal, or financial advice?+
No. Use the tools for planning and documentation hygiene. Rules vary by jurisdiction, income, entity type, and your specific facts. For binding guidance, consult a qualified professional.
Do you track my calculator inputs?+
We do not send raw amounts or personal identifiers to analytics. Where we track usage at all, we record low-cardinality events like page views and CTA clicks.
