Down Payments & Delivery Milestones for Custom Orders
For custom furniture or office interior fit-outs, buyers typically pay a 30%–50% down payment before workshop production begins. Under Article 13(1a) of the VAT Law and PER-11/PJ/2025 Article 31(2)(b), a Tax Invoice must be issued when the down payment is received because payment precedes physical delivery. The remaining balance triggers an invoice upon delivery or handover acceptance (BAST). All invoices must be approved in Coretax by the 20th of the following month (PER-11/PJ/2025 Art. 44). Late approvals incur an administrative penalty of 1% of the tax base (KUP Law Art. 14(4)).
