We confirm the scope, price, payment conditions and delivery target.
D-GATE confirms paid work start after written scope approval, full payment confirmation and receipt of required project materials.
Independent Sales Partner verification
D-GATE may use independent Sales Partners to introduce D-GATE, discuss the service, follow up and support ordinary sales and procurement communication. They are independent contractors, not D-GATE employees.
Sales Partners may continue ordinary follow-up through a clear purchasing decision, including written approval, a purchase order, an invoice request or procurement steps. After an invoice is issued, they may also help identify ordinary procurement or payment-processing blockers.
Sales Partners are not authorized to bind D-GATE or independently decide final technical scope, final price, discounts, payment terms, delivery commitments, refunds or other binding conditions. Formal quotations, order acceptance, invoices, payment instructions, payment-receipt confirmation and work-start confirmation remain with D-GATE.
You may contact D-GATE directly at any stage. To verify a contact, email your company name and the Sales Partner’s name to suematsu@dgate.jp.
Use only payment instructions issued or expressly confirmed by D-GATE. Do not send payment to an independent Sales Partner or use a personal or third-party bank account, wallet, payment link or QR code provided by them. A Sales Partner may follow up on payment status, but only D-GATE confirms receipt and work-start status.
