Do the prices include VAT?
No. US-dollar amounts on this page exclude VAT and sales tax; these are applied on the invoice according to the rules in force. Turkish-lira prices on the Turkish page include VAT.
Are we charged per user?
For ArvoOS and ArvoCal, no: prices are per organization and each plan includes a set number of users; beyond that number only the additional-user fee applies and the plan price does not multiply. For ArvoLab, yes: it is priced per researcher, because there the value is produced directly by the person using it.
Can a team or a company buy ArvoLab?
ArvoLab is sold to individual researchers. Institutional licences are offered only to universities and educational institutions, on request.
What does annual billing save?
On the annual option you pay for 10 months and use 12 — two months free. The amount is invoiced once at the start of the period.
Does the subscription renew automatically?
No. Your card is never charged automatically; as the period end approaches you receive a reminder and a payment link. If you don't pay, the subscription simply ends at the end of the period.
Can we change plan later?
Yes. An upgrade takes effect the same day and only the remaining days of the period are charged; a downgrade applies at the end of the current period.
What happens if prices change?
Your current period is unaffected. Changes are announced at least 30 days in advance and apply from the next period.
We paid annually — what if we cancel early?
The months you used are recalculated at the monthly list price and the remaining balance is refunded; the annual discount is only withdrawn for the unused months.
Is there a discount for taking several products?
Yes — organizations using more than one product get a combined quote. Request a demo to go through the scope.
