Lisälaskuja

Lisälaskuja is a Finnish term referring to additional invoices issued after an initial bill. They arise when charges are adjusted, or new costs appear that were not included in the first invoice. Typical triggers include extra usage (for example, higher consumption of utilities or data), changes to services or products (upgrades, add-ons), corrections of billing errors, or price adjustments implemented after the original billing.

In practice, lisälaskuja are usually itemized and explain the reason for the increase, the amount due, and the payment deadline. They can be issued to both consumers and business customers, and may cover short-term adjustments, late charges, or one-time fees tied to a contract or delivery.

Consumers and businesses have a responsibility to review lisälaskuja carefully. If a charge is unclear or appears incorrect, it is common to contact the supplier, request an itemized explanation, and provide any supporting documentation. Generally, the undisputed portion of a bill remains payable, while disputed amounts are addressed through the supplier’s dispute process or, if needed, through consumer protection channels or contractual remedies.

To minimize disputes, contracts should define pricing, estimates, and change procedures clearly, and invoices should be transparent and timely. In Finland, invoicing practices are governed by general consumer protection and contract law, which promote clear, accurate billing and fair handling of adjustments.
