Merchant Fees, Rates, and Pricing Models
When is flat-rate processing cheaper than interchange-plus?
Understanding when flat-rate processing is cheaper than interchange-plus pricing is essential for merchants looking to optimize their payment processing costs. Both pricing models have their advantages depending on your business type, transaction volume, and average ticket size.
Flat-Rate vs. Interchange-Plus: What’s the Difference?
Flat-rate processing charges a fixed percentage fee on all transactions, regardless of card type or transaction size. Interchange-plus pricing, on the other hand, passes through the interchange fees set by card networks plus a fixed markup from the processor.
When Is Flat-Rate Processing More Cost-Effective?
Flat-rate processing tends to be cheaper for businesses with low transaction volumes, smaller average ticket sizes, or a high percentage of consumer credit card transactions. This pricing model simplifies budgeting since fees are predictable and consistent.
- Small businesses with limited monthly sales
- Merchants with mostly low-value transactions
- Businesses that prefer straightforward, predictable fees
- Companies without the resources to analyze complex fee structures
Conversely, interchange-plus pricing usually benefits high-volume merchants or those with larger average transaction amounts, as it can result in lower overall fees by passing through actual interchange costs.
