What Makes a Business "High-Risk"?
Banks and payment processors classify a business as high-risk based on factors including: industry type, chargeback history, average ticket size, monthly volume, time in business, owner credit history, and geographic market. Being labeled "high-risk" is not a judgment β it's a technical classification. Diaz Solutions finds you a processor that understands your business.
Apply for High-Risk Account βACH & eCheck Payment Processing

Merchant Services Questions & Answers
The most common questions Long Island business owners ask about credit card processing, POS systems, fees, and payment solutions.
What is a merchant account and do I need one?
A merchant account is a specialized bank account that allows your business to accept credit and debit card payments. Any business that wants to process card payments β whether in-store, online, or on mobile β needs a merchant account or a payment facilitator like Diaz Solutions.
How much does credit card processing cost for a small business?
Credit card processing fees typically range from 1.5% to 3.5% per transaction depending on your pricing model. Interchange-plus pricing offers the most transparency β you pay the raw interchange rate plus a small markup. With our cash discount / dual pricing program, you can bring your effective cost to zero.
What is a cash discount program and is it legal?
A cash discount program is a fully compliant method that offers customers a discount for paying with cash, while card-paying customers pay the standard listed price. Cash discount programs are legal in all 50 states and compliant with Visa, Mastercard, and all major card brands when set up correctly β which is exactly what Diaz Solutions specializes in.
What is dual pricing and how is it different from surcharging?
Dual pricing means displaying two prices at the point of sale β a cash price and a credit card price. Surcharging means adding a fee on top of the listed price for card users. Dual pricing is legal in all states, while surcharging has restrictions in some states. Diaz Solutions sets up both programs with full compliance guidance.
How do I reduce my credit card processing fees?
There are several strategies to reduce fees: (1) Switch to interchange-plus pricing for maximum transparency, (2) Implement a cash discount or dual pricing program to eliminate fees entirely, (3) Negotiate a lower markup with your current processor, or (4) Work with a consultant like Santos Diaz at Diaz Solutions who can audit your current statement and find savings immediately.
What is a high-risk merchant account?
A high-risk merchant account is a payment processing account for businesses that operate in industries with elevated chargeback rates, regulatory scrutiny, or high-ticket transaction values. Industries like CBD, nutraceuticals, online gaming, travel agencies, and credit repair services are typically classified as high-risk. Diaz Solutions works with specialized processors to get high-risk businesses approved and processing.
What is interchange-plus pricing?
Interchange-plus pricing is considered the most transparent pricing model in the industry. You pay the actual interchange rate set by Visa/Mastercard plus a fixed markup from your processor. This is in contrast to tiered or flat-rate pricing, which bundles fees in ways that can result in overpaying. Most small businesses save money by switching to interchange-plus.
How do chargebacks work and how can I prevent them?
A chargeback occurs when a customer disputes a credit card charge with their bank, resulting in the funds being reversed from your merchant account. Chargebacks cost merchants the transaction amount plus chargeback fees (typically $15β$100 each). Prevention strategies include clear return policies, delivery confirmation, strong customer service, and AVS/CVV verification. Diaz Solutions offers chargeback management solutions for high-risk merchants.
What is PCI compliance and do I need it?
PCI DSS (Payment Card Industry Data Security Standard) compliance is a set of security standards required for any business that accepts, processes, or stores credit card data. All merchants are required to be PCI compliant. Failure to comply can result in fines and the loss of your ability to accept cards. Diaz Solutions helps every client achieve and maintain PCI compliance.
What is ACH payment processing?
ACH (Automated Clearing House) processing allows businesses to accept electronic payments directly from a customer's bank account. ACH is significantly cheaper than credit card processing (often under 1% or a flat fee per transaction) and is ideal for recurring billing, large-ticket B2B payments, and industries that prefer bank transfer payments.
How long does it take to get approved for a merchant account?
Standard merchant account approvals typically take 1β3 business days. High-risk merchant accounts may take 5β10 business days due to more thorough underwriting. Diaz Solutions works to expedite approvals and can often get businesses processing within 24 hours for standard accounts.
Can I switch merchant service providers without penalty?
It depends on your current contract. Many processors lock businesses into multi-year contracts with early termination fees (ETFs). Diaz Solutions offers no-contract and month-to-month options. We can also review your current contract and help you determine the most cost-effective time to switch.
What POS systems do you support in Long Island, NY?
Diaz Solutions supports and installs a wide range of POS systems including Clover, Toast, Square, PAX, Dejavoo, Ingenico, and custom tablet-based solutions. We provide on-site installation, staff training, and ongoing technical support across Nassau and Suffolk County on Long Island.
Do you offer same-day or next-day deposits?
Yes. Diaz Solutions works with processors that offer next-day funding as standard, and same-day deposit options are available for qualifying merchants. Fast funding is critical for cash flow β especially for restaurants, delis, and retail businesses.
What payment methods can I accept with Diaz Solutions?
With Diaz Solutions, you can accept: Visa, Mastercard, American Express, Discover, JCB, UnionPay, Apple Pay, Google Pay, Samsung Pay, PayPal, Venmo for Business, ACH/eCheck, wire transfers, and PIN debit. We support contactless NFC, chip (EMV), swipe, and card-not-present transactions.
