Does an online store need a cash register
When working with Invoicebox, an online store doesn't need to buy cash register equipment (KKT) — this is established by law.
Why a cash register isn't needed
Under Federal Law No. 54-FZ, a receipt is issued at the moment of settlement. Payment for goods and services is received directly by Invoicebox (OOO ORTS) — so the obligation to issue receipts falls on it.
Who issues the receipts
Invoicebox has its own cash register equipment: the service issues electronic receipts in full compliance with Russian legal requirements. Details — in the article Who issues receipts under Federal Law No. 54-FZ, and how.
