  • Payment of the total invoice amount, without offset or deduction, is due five (5) days from the invoice date or as otherwise approved in writing by Whois API. On any past due invoice, Whois API may charge (i) interest from the payment due date to the date of payment at 18% per annum, plus reasonable attorney fees and collection costs; or (ii) the maximum amount that is allowed under the applicable law, whichever is less. At any time, Whois API may change the terms of Customer’s credit, require financial data from Customer for verification of Customer’s creditworthiness, require a bank guarantee or other security, or suspend any outstanding Purchase Order Forms of Customer. Whois API may apply payments to any of Customer’s accounts. If Customer defaults on any payment under this Agreement, Whois API may reschedule or cancel any outstanding delivery and declare all outstanding invoices due and payable immediately. Unless otherwise provided by applicable law, any credit issued by Whois API to Customer in respect of any of Customer’s accounts will expire if unused for twelve (12) months following the date of issuance of such credit.
  • Payment & Documentation of Taxes. All prices quoted are exclusive of all applicable sales, use and other related taxes. Whois API shall invoice Customer for all taxes applicable to payment of fees pursuant to this Agreement, itemized by type and jurisdiction, which Whois API is required by law to collect from Customer.
  • Entity Size. Fees described herein or in any Purchase Order Form are based on, among other factors, the size of the licensing entity. Notwithstanding anything to the contrary within this Agreement or on any Purchase Order Form, upon any increase of the licensing entity employee count of more than twenty percent (20%), the licenses granted herein shall cease to be effective, and the parties shall mutually agree upon different pricing. For the avoidance of doubt, upon the merger with, purchase by, or purchase of another entity, all employee counts shall be aggregated. Should two or more entities with licenses to Whois API products merge or otherwise become structured in a way to be under common control, license fees shall continue to be due for such products under separately entered license agreement.

Invoice Disputes

Within thirty (30) days of the invoice date, Customer must notify Whois API in writing and provide sufficiently detailed support of any invoice dispute. If Customer fails to do so, Customer is deemed to have waived its right to dispute that invoice and the invoice will be deemed accurate and valid.

The obligation to keep information confidential shall not apply to any such information that has been disclosed in publicly available sources; is, through no fault of Customer, disclosed in publicly available source; is in the rightful possession of Customer without an obligation of confidentiality; or is required to be disclosed by operation of law, provided the Customer provides Whois API with prior written notice of said required disclosure; thereby, affording Whois API an opportunity to contest said disclosure and protect its Confidential and/or Proprietary information.

The terms “Processor”, “Controller”, and “Processing” shall have the meanings prescribed to them within the GDPR.
