    Remitware Payments

    We build payment solutions for SMBs so they can concentrate on growing their companies. When you create a payment before 2pm ET (this is critical), we’ll initiate the direct debit transaction immediately. Next step is to wait for your bank to release the funds to us. This typically takes one business day. Once we’ve received the funds, your recipient gets their payment by 9pm ET the same day. The entire process, including waiting on your bank, only takes 1-2 business days. This one is pretty simple and super fast. If you’ve already added funds to your Remitr Ledger, any payment initiated before 2pm ET gets to your recipient by 9pm ET on the same day! The vast majority of international payments on the Remitr platform can be made for just $5. Simply initiate the payment and leave the rest to us. No more cheques, no more delayed payments, no more bank visits. Keep reading to see how our most popular international payment funding types work.
    Starting Price: $5 per transaction
