Frequently Asked Questions
Are these tools free to use?+
Yes. The tools on this page are free to use and do not require sign-up.
Can I use these tools without becoming a Gruv customer?+
Yes. These tools are designed to be useful on their own. If you later use Gruv, the same concepts — invoicing, compliance gates, payouts, and reconciliation — can become part of a live workflow.
Is my data private?+
Most tools run calculations in your browser and store drafts locally on your device. When a tool calls an external service (e.g., VAT validation via VIES), it will say so explicitly.
How do these tools relate to the Gruv platform?+
They reflect common operational questions in global work and money movement: pricing, compliance, residency, documentation, and payout planning. Gruv builds workflows around those decisions so teams can move from an answer to an operating process.
Is this tax, legal, or financial advice?+
Use the tools for planning and documentation hygiene. They are not tax, legal, or financial advice, and rules depend on jurisdiction, income, entity type, and your specific facts. When you need certainty, consult official guidance and a qualified professional.
Do you track my calculator inputs?+
We avoid sending sensitive inputs to analytics. Where we track usage, we prefer low-cardinality events (buckets, on-page CTAs) instead of raw amounts or IDs.
