Selling Dietary Supplements Online: How to Avoid Merchant Account Declines

Prerequisites: What You Need to Know Before You Start

The dietary supplement market is booming, with a projected annual growth of 8.9% until 2030. However, this dynamism also attracts close scrutiny from banks and payment processors. Classified as "high-risk," this sector is associated with high chargeback rates, strict regulations, and sometimes deceptive business practices.

Even before submitting your first merchant account application, it's crucial to understand that acquiring banks will assess the viability and compliance of your entire business. A simple website is not enough. You must prepare solid legal documents, a transparent return policy, and, most importantly, present your products in a way that avoids any unproven therapeutic claims. This is the cornerstone for building a relationship of trust with your payment partner and avoiding a rejection that could paralyze your business before it even launches.

Avoiding Bank Rejections: A Step-by-Step Guide

Step 1: Build an Impeccable Refund and Return Policy

The chargeback rate is the number one enemy of nutraceutical e-commerce merchants. A rate above 1% can lead to the closure of your merchant account. The first line of defense is a clear, transparent, and easy-to-find refund policy. Customers who don't understand how to return a product or get a refund are more likely to dispute the transaction with their bank.

Your policy should be written in simple language and specify the conditions (unopened product, 30-day window, etc.), the procedure (contact support, receive a return label), and the refund processing times. Display a link to this policy in your site's footer, on your product pages, and even in the order confirmation email. Pro tip: Consider a 30-day "money-back guarantee." While this may increase returns, it significantly reduces disputes and demonstrates confidence in your product quality: a strong signal for acquiring banks.

Step 2: Eliminate All Therapeutic Claims

This is the most critical point and the one that causes the most rejections. Regulators like the FDA in the United States or the DGCCRF in France strictly prohibit presenting a dietary supplement as a treatment or cure for a disease. Your product pages, blog posts, and advertisements must never use terms like "cures," "treats," "prevents," or refer to specific diseases (e.g., "lowers cholesterol," "combats diabetes").

Focus on authorized health and structure/function claims related to general well-being. For example, instead of saying "cures insomnia," use "promotes restful sleep." Use scientific sources to back up your statements, but present them as information about the ingredients, not as proof of the final product's effectiveness. Bridge Pay thoroughly analyzes your site during the underwriting process to identify these "red flags." A non-compliant site will be systematically rejected by our partner banks.

Step 3: Make Subscription Billing Transparent

Subscription models are excellent for LTV (Customer Lifetime Value) but are a major source of disputes if they aren't transparent. The practice of "forced subscriptions" or "free trials" that convert into expensive subscriptions without a clear warning should be avoided. The bank will see this as an attempt to deceive the customer. Your checkout page must clearly state that it is a subscription.

The customer must actively check a box (no pre-checked boxes) to accept the terms. The information to display includes: the amount and date of the first charge, the frequency and amount of recurring charges, and clear instructions on how to cancel the subscription. Implement a customer portal where subscribers can manage, pause, or cancel their subscription in a couple of clicks. A customer who can easily unsubscribe will not file a chargeback.

Step 4: Cultivate Your Online Presence and Reputation

Bank underwriters don't just analyze your website. They Google your company and its executives. They search for customer reviews on platforms like Trustpilot or Avis-Vérifiés. A poor reputation, fraud complaints, or negative comments about product quality are all red flags. Before submitting your application, be sure to manage your online reputation.

Encourage satisfied customers to leave positive reviews. Respond professionally and constructively to negative reviews by offering solutions. Having well-maintained company profiles on social media (LinkedIn, Facebook) also adds credibility. A faceless company with no history or visible team inspires distrust.

Step 5: Prepare a Complete Compliance File (KYC/KYB)

To get a merchant account, you will need to go through a "Know Your Customer" (KYC) and "Know Your Business" (KYB) process. Prepare these documents in advance to speed up the process. This typically includes: the company's articles of incorporation, a recent business registration certificate (less than 3 months old), identification for directors and major shareholders (owning over 25%), proof of address, and a company bank account statement.

Additionally, prepare a document presenting your business plan: sales projections, marketing strategies, and a description of your supply chain (suppliers, warehousing). The more complete and professional your file is, the more you demonstrate the seriousness of your business. Bridge Pay supports you with a detailed checklist of the required documents so you don't miss anything.

Verification: How to Know if Your Setup is Solid

Once your merchant account is approved and active, vigilance is still required. The real test comes in the first 3 to 6 months of activity. Carefully monitor your chargeback rate from the dashboard provided by your payment processor, like Bridge Pay. A rate that consistently stays below 0.75% is an excellent indicator.

Also, analyze the reasons for these disputes: are they related to fraud, product dissatisfaction, or a misunderstanding of the billing? This data is a goldmine for optimizing your processes. Finally, an unmistakable good sign is a lack of communication from your payment partner's "Risk" department. If no one is calling you to freeze your funds or question your transactions, it means your business is operating by the book and inspiring confidence.

Troubleshooting: Common Problems and Solutions

Problem: My chargeback rate is suddenly spiking.
Solution: Investigate the source immediately. A sudden increase may be due to an aggressive advertising campaign that attracted low-quality customers, or to "friendly fraud" (the customer receives the product but disputes the transaction). Contact the affected customers to understand the problem. Use fraud prevention tools that analyze transactions in real time. Bridge Pay integrates 3D Secure 2.0 filters and scoring tools to block the most suspicious transactions before they are even authorized.

Problem: The bank is holding a portion of my funds (a "rolling reserve").
Solution: A "rolling reserve" is a common practice in high-risk industries to cover potential chargebacks. A bank may hold 5% to 10% of your revenue for a period of 60 to 180 days.

If this happens, it's often because your application was borderline or your initial business activity showed signs of risk. The best solution is to maintain an excellent track record over several months. You can then renegotiate this reserve with your payment partner, providing evidence to support your case (low dispute rate, high customer satisfaction).

Problem: My advertising account (Facebook, Google Ads) has been suspended.
Solution: Advertising platforms have even stricter rules than banks regarding health claims. A suspension here is a huge warning sign. Immediately audit all your ads and landing pages to remove any non-compliant language. This is often the same root cause that leads to a bank rejection. Do not create a new ad account to bypass the suspension; this will only make your case worse. Fix the problem at its source: your marketing compliance.
