A mobile POS should let your team take payment where the job happens without carrying unnecessary equipment. Compare mobile POS costs for small business with the phone or tablet, reader, software and processing charges required for your service business.
For POS systems, a card reader price is only the starting point. Ask how staff create a charge, send a receipt and reconcile the payment afterward. A system that takes a card easily but creates bookkeeping work may not be the cheapest complete solution.
Readers, Phones and Apps
Ask which devices and operating systems the proposed payment app supports. Confirm whether you need a separate reader or can use a supported tap-to-pay function, and what payment types each arrangement accepts. Do not assume every phone supports the same features.
Square markets mobile payment hardware and app-based POS options, illustrating the range of setups available. The POS systems buying guide helps you compare the payment workflow before choosing hardware solely because it is small or inexpensive.
Mobile Payment Processing Costs
Request the fee schedule for in-person, manually entered and remotely paid transactions where you use them. Ask about any fixed transaction component, recurring software charge and other required fees. A service business with a small number of large invoices can have different economics from one taking many small payments.
Review POS systems prices using a sample month from your own business. Apply each provider’s actual schedule to the same transaction mix and label the result as an illustration. Include refunds or other relevant events rather than assuming every transaction is a straightforward sale.
Ask how deposits, final balances and invoices are handled. Confirm whether those functions require another subscription or change the processing rate. A mobile terminal and an invoicing system should work together if your business routinely collects money in more than one stage.
Published Mobile Reader and Payment Prices
Square’s US reader page checked in November 2026 lists the contactless-and-chip reader at $59 and in-person processing at 2.6% plus $0.15. At that stated rate, a hypothetical 100 payments of $100 incur $275 in processing: $260 percentage fees plus $15 fixed fees. Add one $59 reader for a $334 initial subtotal, excluding tax, phone, connectivity and optional services. Different plans or transaction types can have different rates.
Connectivity and Staff Use
Have the provider explain what happens when a jobsite has poor connectivity. Do not assume offline acceptance is available or risk-free; ask for the actual conditions, limits and responsibility under the agreement. Check how staff access the system without sharing one uncontrolled account.
Use the POS systems FAQs to prepare the broader questions. Test a complete example from charging the customer to finding the payment in your records, including a receipt and a correction. Choose the mobile POS that makes those everyday tasks simple at a transparent price. The best value is a working payment process, not merely the lowest advertised reader cost.
