Choosing under constraint: How do owners choose a POS system?

Small firm owners make many consequential decisions every day. Some are clearly strategic, such as when to hire workers, whether to expand their operations, or how to finance that growth. Others are more routine, but no less important, for example which accounting software to use, how frequently to run payroll, or which technologies to adopt. Although making the wrong choice can have lasting impact, these decisions are often made while owners are juggling the day-to-day pressures of running a small firm, with limited time and resources, and with imperfect information.

Many of the decisions owners make have long term consequences. For instance, choosing a lender, a payroll provider, or adopting a new technology can lock in costs, workflows, and contracts that are hard to undo. Yet we know little about how firm owners access information, weigh pros and cons, seek advice, and ultimately make decisions about their business operations. Understanding these factors is key to building better tools and resources to support them.

Adopting POS systems

Point-of-sale (POS) systems are an instructive example. These systems have increasingly become an essential tool for many small firms. Beyond processing payments, they help firms manage inventory, schedule workers, track sales, and interact with customers. Choosing a POS system is no longer the simple decision it used to be; it is an operational choice with long-term, sometimes locked-in, implications. 

A desktop review of major POS providers highlights just how difficult it is for small firms to make meaningful comparisons. As we’ll see, information on system capabilities and fees is inconsistently presented and communicated with varying levels of complexity. Pricing that looks simple upfront can mask the true long-run cost of the system, which may require “upgrades” and further fees as new functions are added. On the other hand, owners may not realize upfront that a system can’t grow with their business, leaving them to adopt additional tools, at an additional, unforeseen cost.

How fees and products are presented

Some platforms present pricing in a highly structured, self-service format. For example, Square organizes its POS offerings by industry and clearly displays monthly subscription tiers, payment processing rates, and hardware options directly on its website. An owner can see, without speaking to a sales representative, how pricing changes as features are added, how transaction fees differ for in-person versus online payments, and which hardware might be appropriate for a single register versus a more complex setup. This lets owners compare their initial options easily.

Other platforms emphasize transparency around plan structure but present a large volume of information that can be difficult to parse, especially for time-constrained small firm owners. Shopify clearly publicizes its subscription prices, card rates, and feature tiers, but its POS functionality is embedded within a larger e-commerce platform meaning firms must consider the cost of the entire ecosystem, not just the POS itself. For very small firms, the sheer number of features, add-ons, and product tiers can make it challenging to determine what they actually need and what their total costs are likely to be.

Some providers take a more sales-driven or modular approach. Toast places its pricing structure front and center, often advertising low or zero-cost starter options. However, many features that become important as a restaurant grows, such as payroll, scheduling, delivery integrations, or catering, are offered as add-ons that require custom quotes by a sales representative. For an owner trying to compare systems upfront, it can be difficult to tell how much functionality is included at the advertised price versus how much more it will cost once they’re up and running.

Comparing costs: why the “upfront price” rarely tells the full story

One of the biggest challenges small firms face when choosing a POS system is that costs are not only difficult to compare across providers, they often change a lot over time. What appears affordable or even “free” at the outset can become substantially more expensive as a firm grows, adds staff, increases transaction volume, or needs additional functionality. 

Moreover, even when headline prices are clearly posted, key details can be easy to miss. Fees are often listed exclusive of taxes, some charges are deducted automatically from transaction proceeds rather than billed separately, and dispute or chargeback fees, renewal terms, or early termination penalties may be buried in terms and conditions rather than highlighted alongside advertised pricing.

Some providers structure pricing so that entry-level plans are inexpensive, or even advertised as free, but rely heavily on transaction fees and paid add-ons as firms scale. Square illustrates this well: while its base plan and processing fees are clearly displayed, the total cost firm owners incur can rise substantially as transaction volume increases or firms layer on features like payroll, marketing tools, or loyalty programs. Adding to this is the fact that many of these add ons might not feel optional the longer the owner integrates the platform into their internal systems. The more a firm invests in a particular system (whether in time, training, and data migration) the harder it becomes to justify switching, even when add-on costs are high. Toast’s platform is similar: the low advertised entry price turns into a much higher effective cost as a restaurant adds scheduling, delivery integrations, and catering tools over time.

Providers like Stripe use a pay-as-you-go approach, with no monthly subscription for core payments but fees that vary based on transaction type, card origin, currency conversion, and optional services. For firms with fluctuating revenue or international customers, total costs can vary significantly month to month, making budgeting more complex, even when headline pricing is transparent.

Across all pricing models, the key challenge for small firms is how hard it is to predict future costs when owners are seeking these services based on “in-the-moment” needs. If they commit without comparing long-term costs across providers, owners may only discover how expensive or restrictive a system is once they are already reliant on it. 

Why this matters

These dynamics are not unique to POS systems but they provide a useful illustration of how small firms encounter hidden complexity when making operational decisions. Understanding how small firm owners navigate these decisions, and where information gaps, cognitive overload, or pricing complexity shape outcomes is critical to drive efforts to improve technology adoption, reduce costs, or design more inclusive financial products. 

The stakes are particularly high for small firms because, unlike large businesses, they rarely have dedicated procurement teams, legal counsel, or IT staff to evaluate contracts and project total costs over time. Instead, owners with multiple priorities competing for their attention and in many cases limited experience with these systems are making long-term decisions under time pressure and with information that is often incomplete or obscured realities.

This also has distributional implications. Firms with lower revenues, less savings, or owners with less prior experience in a given industry may be disproportionately affected by unexpected cost increases. This has the potential to turn tools that are intended to streamline firm operations and reduce time burdens into new pain points for owners, compounding the financial pressures they experience. 

For researchers and policymakers, the POS example points to a broader research agenda central to understanding how small firms really operate. What information do small firms actually use when making decisions on how to operate their business? To what extent do owners rely on peer networks, formal mentors, or other channels in making these decisions? What information is obscured or hidden by product providers, and how do we increase transparency?
