As a supplier on Cellbase, you're responsible for your own tax obligations. Documentation requirements are straightforward.
Required documentation:
All suppliers must provide:
Business registration documents
Tax identification or registration number
VAT registration details (if VAT-registered)
Authorised signatory information
Your tax responsibilities:
Product sales: You're responsible for:
Determining applicable VAT/tax on each sale based on buyer location
Issuing your own VAT invoices to buyers
Reporting and remitting any VAT/tax due in your jurisdiction
Maintaining accurate tax records
Cellbase operates as a marketplace facilitator. We don't collect VAT on product sales - you handle all product tax obligations as the seller of record.
Issuing invoices:
After each sale, upload your official tax invoice to the order. This provides buyers with the tax documentation they need and completes the transaction.
Your invoice should include:
