We prefer electronic invoicing, and invoices should primarily be sent as e-invoices to the invoice transmission service using the following details:

Recipient name: Tamsin Oy
E-invoice address: 003724446736
Operator: Open Text Oy
Operator address: 003708599126

Alternatively, invoices can be sent electronically to the scanning service at tamsinoy@app.fennoa.com.

Text in the body of the email message will not be considered when processing the invoice. The sender is responsible for ensuring that invoices sent by email are delivered. Rejected invoices will be returned to the sender’s address. Invoices received by email are retained for 1 month, after which they are destroyed.

Requirements for invoices sent to the scanning service:

• Tamsin Oy’s invoicing address must be readable on the email invoice
  in the same way as on a paper invoice:
  Tamsin Oy
  c/o Yrityspalvelu Instament Oy
  Rintalantie 74 A
  64760 PELTOLA
• The invoice attached to the email must be in PDF format.
• The invoice must be attached to the email.
• All pages of the invoice must be included in the same file. The invoice cannot be split
  across multiple emails or attachments.
