The Best International Payment Processor For Your B2B Business

April 29, 2024

Your business has been scaling, and you're ready to start selling your services or goods internationally.

That’s a massive step toward increasing your revenue and taking your business to new heights, but it comes with its own set of unique challenges. If your payment processor charges cross-border and currency conversion fees, these costs can add up and cut into your profits.

In fact, most traditional payment processors charge an additional 1.4% or more for international transactions, on top of their regular processing fees. To give you some perspective on how costly these fees can be, let’s say you’re generating $1M in revenue on foreign transactions. If you pay 1.4% in cross-border fees, that’ll cost your business a staggering $14K.

At Quantum ePay, we’re delighted to share that we now offer international payment processing with zero cross-border and currency conversion fees. That means you can maximize your profits as you expand your business globally. Imagine all the ways you can reinvest in your business when you no longer have to worry about unnecessary foreign transaction fees!

How our international payment processing works

Are you curious about how exactly our international payment processing works? Let’s break it down into the two ways it can function.

International payment processing through invoicing:

  1. Through our proprietary Qoin payment platform, you can create an invoice and select your customer’s local currency.
  2. Your customer enters their card details to pay the invoice.
  3. Our interface automatically detects an international card and routes the transaction through a local processor.
  4. The results are optimized approval rates, removal of cross-border fees, and removal of currency exchange fees.

International payment processing through full integration:

  1. Our team will work with you to fully integrate our Qoin payment platform directly into your website or software platform.
  2. Your customer arrives at the checkout page and enters their card details.
  3. Our interface automatically detects an international card and routes the transaction through a local processor.
  4. The results are optimized approval rates, removal of cross-border fees, and removal of currency exchange fees.

That’s it—no cross-border fees or currency conversion fees! We’ve made foreign transactions easier than ever.

8.1. Governing Law and Jurisdiction. The Parties intend that this Agreement be construed and enforced in accordance with the laws of the State of California without regard to any conflict-of-law or choice-of-law rules, and that the rule of construction that provides that a document is construed against the maker thereof be inapplicable in the construction of any of the terms of this Agreement. The Uniform Computer Information Transactions Act, and the United Nations Convention on the International Sale of Goods, shall not apply to this Agreement.

8.2. Dispute Resolution. Any dispute, claim, or controversy arising out of or relating in any way to this Agreement or the breach, termination, enforcement, interpretation, or validity thereof, including the determination of the scope or applicability of this agreement to arbitrate, or in connection with Merchant’s use of the Services or our websites, shall be determined through confidential binding arbitration before one arbitrator. The confidential binding arbitration shall be administered by AAA pursuant to its Commercial Arbitration Rules, and the parties shall maintain the confidential nature of the arbitration proceeding and the award, including the hearing. Judgment on the award may be entered in any court having jurisdiction. Notwithstanding the foregoing, this Agreement shall not preclude either party from pursuing a court action in the state or federal courts for the sole purpose of obtaining a temporary restraining order or preliminary injunction in circumstances in which such relief is appropriate; provided that any other relief shall be pursued through an arbitration proceeding pursuant to this Agreement. In any event, any action or proceeding by Merchant against Quantum Electronic Payments LLC relating to any dispute must commence within one year after the cause of action accrues.

8.3. Prohibition of Class and Representative Actions and Non-Individualized Relief.

Also, the arbitrator may award relief (including monetary, injunctive, and declaratory relief) only in favor of the individual party seeking relief and only to the extent necessary to provide relief necessitated by that party’s individual claim(s).

8.4. Pre-Arbitration Dispute Resolution. Quantum Electronic Payments LLC is always interested in resolving disputes amicably and efficiently, and most concerns can be resolved quickly and to the participant’s satisfaction by contacting Quantum Electronic Payments LLC’s support team. If such efforts prove unsuccessful, a party who intends to seek arbitration must first send to the other, by certified mail, a written notice of dispute (the “Notice of Dispute”). The Notice of Dispute must (i) describe the nature and basis of the claim or dispute and (ii) set forth the specific relief sought. If Quantum Electronic Payments LLC and Merchant do not resolve the claim or dispute, despite good faith attempts, within sixty (60) calendar days after the Notice of Dispute is received, Merchant or Quantum Electronic Payments LLC may commence an arbitration proceeding. During the arbitration, the amount of any settlement offer made by either party shall not be disclosed to the arbitrator until after the arbitrator determines the amount, if any, to which the parties are entitled.

8.5. No Waiver. The failure of either party to enforce any right or provision in this Agreement will not constitute a waiver of such right or provision unless acknowledged and agreed to by such party in writing; and any waiver with respect to a specific circumstance will not constitute a waiver of the same provision or any other provision of this Agreement for any subsequent circumstance unless expressly provided by such written agreement, except that Quantum Electronic Payments LLC may modify this Agreement to comply with, and as a result of, amendments to Applicable Laws and Rules. The Section headings are provided merely for convenience and will not be given any legal import in the interpretation or enforcement of this Agreement.

If any provision of this Agreement is held by an arbitrator or court of competent jurisdiction to be invalid or unenforceable, if the essential terms and conditions of this Agreement for each party remain valid, binding, and enforceable, then such provision(s) will be deemed to be restated and construed to reflect the original intentions of the parties in accordance with Applicable Law and Rules with respect to the invalid or unenforceable provision(s), and with all other provisions of this Agreement remaining in full force and effect.

8.7. Assignment. Merchant may not assign this Agreement without the prior written approval of Quantum Electronic Payments LLC, such approval not to be unreasonably withheld or delayed.

8.8. Electronic Signature. Signatures transmitted and received electronically, such as through transmission of a scanned or faxed document, or via secure email or a service such as AdobeSign or a process that otherwise requires typing your name and acknowledging it as an electronic signature, or electronically indicating assent, acknowledgement or acceptance of an agreement, document or other writing, are true and valid signatures for all purposes hereunder and shall bind the parties to the same extent as that of a live signature on paper. Any transactions or services resulting from the Merchant’s instructions which Quantum Electronic Payments LLC receives in the Merchant’s name or under the Merchant’s credentials, including any electronic signature, shall be deemed to have been “a writing” and authenticated by the Merchant “in writing” for purposes of any law in which a writing or written signature is needed or required. All electronic signatures and records maintained by Quantum Electronic Payments LLC of transactions under the Merchant’s or its authorized users’ credentials shall be deemed to have been “signed” and will further constitute an “original” when printed from records established and maintained by Quantum Electronic Payments LLC or its agent in the normal course of business. The Merchant agrees not to contest the authorization for, or validity or enforceability of, Quantum Electronic Payments LLC’s electronic records and documents, or the admissibility of copies thereof, under any applicable law relating to whether certain agreements, files or records are to be in writing or signed by the party to be bound thereby. Records and “signed” documents, if introduced as evidence on paper in any judicial or other proceedings, will be admissible to the same extent and under the same conditions as other documentary business records.

8.9. Representatives. Each party shall be primarily responsible for each of its respective Representatives’ compliance with this Agreement.
