If you’re looking for ways to increase your profitability by processing purchases faster, look no further than Square and Fattmerchant. Both POS and payment processing systems allow you to seamlessly and quickly accept payments at a payment station, on mobile devices, or through online invoicing.
Fattmerchant focuses on providing exceptional merchant services, with features including card-present payments, mobile payments, invoicing, eCommerce, business reporting and analytics, and an API for direct integration with other platforms. They also provide customer tracking throughout all stages of their lifecycle, team management, and per-product sales reports.
Square is perhaps the most popular POS system on the market, mostly due to its fast setup and ability to accept payments with ease. The streamlined platform has essential features like secure payments, inventory management, loyalty programs, loyalty programs, CRM, and more.
In our Fattmerchant vs. Square comparison, we found that Fattmerchant is better for companies selling high-ticket items and conducting a large volume of transactions, while Square is better for smaller businesses. This is because Fattmerchant offers a flat rate payment processing subscription, while Square charges a percentage fee off each transaction.
If you process more than $80,000 annually, Fattmerchant charges a flat $99 per month (plus $0.08 per transaction). This works out to less than 1.5% per transaction, which is a total steal. For companies that sell less than $80,000, they charge 2.9% + $0.08 per transaction.
Square, on the other hand, charges 2.6% + $0.10 per transaction. This is a much better per-transaction rate for businesses accepting smaller purchases, but it really adds up once you start to scale.
Both platforms also allow for integration with popular apps like Quickbooks for expanded functionality. Let’s dive into the features, pricing, and support offered by both companies.

Reporting and Analytics

The Difference Between Reporting and Analytics
The first thing you need to understand is that reporting translates data into information, while analytics transforms that information into insights. While reporting alerts people to what is happening and how it might affect them, analytics provides insights into why things are the way they are and what can be done to improve performance. Reporting is the collection, collation and dissemination of information relating to the business environment. It enables enterprises to monitor their online business and provide insights to decision makers. It includes data visualization, consolidation and organization, and standardized formatting of reporting output. It also enables self-service and ad hoc responses through real-time reporting solutions. A good example of this is a dashboard that displays all relevant KPIs in a concise, clear and structured manner. It allows users to drill deeper into a specific area of the dashboard to view the information in more detail and offer more context. A good rule of thumb is to limit the number of KPIs displayed to no more than three to six, as too many can lead to decision fatigue and overwhelm. A good example of this is system process maps (or flows) that describe the end-to-end sequence of a given business process. They identify bottlenecks and help uncover opportunities to solve problems to bring the business from its current sub-optimal state to a better future state. The results of these analyses are presented to decision makers to facilitate discussions and find solutions that will ultimately bring value.Online Payments

Fattmerchant Costs

The reason for a subscription-based model is that Fattmerchant does not charge an interchange fee. This is a non-negotiable rate set by card brands like Visa and Mastercard. They are variable on a number of factors including whether the card is credit or debit, how the payment is made (swipe or tap), and if the card is rewards or corporate.
Most payment processors include the interchange rate in the processing cost, so you never know what you are spending per transaction. Fattmerchant charges a monthly subscription to get the lowest rate possible.
The cost per transaction will change depending on the subscription you choose. These break down as such:
Customer Service and Support

Square offers the same level of support. However, since the brand has been around longer, they tend to have some complaints. This is especially apparent when it comes to the account termination process. When your account is closed for any reason, you are sent an email with no option to appeal.
Square answers all queries via phone or email. The 24/7 support center offers tons of materials like:
- POS tips
- Articles
- Guides
- FAQ
- Videos
There is also a seller community where you can interact with peers.
The Final Take
Choosing between Fattmerchant and Square may just boil down to the size of your company. When running high-volume transactions, a subscription-based model like Fattmerchant tends to save money. You are not being nickeled and dimed for every card that is run.
However, this can also be costly for a business that may only process a few transactions per month. If you are on the smaller end of the business spectrum, Square might be the best choice. The amount saved through Fattmerchant may not be enough to offset the subscription cost.
Fattmerchant is an a la carte service while Square is more inclusive. So, take that into consideration when making your choice as well. How much time do you have for customization? Do you need something up and running now? Considering these factors will help you decide which platform will drive growth, improve relationships, and add to your company’s bottom line.
