“Self-service in Practice” — Part 2
“How long will it take to pay for itself?” This is one of the first questions we receive when someone starts exploring a self-service system. The question is perfectly logical, but there is no single answer that applies to everyone.
A kiosk in a fast-food restaurant, a system for institutional and industrial food service, cash payment devices, and various software automations solve different problems. These include artificial intelligence systems that monitor for shortages or discrepancies, as well as software that sends orders from food delivery platforms directly to the screen of the system used by the restaurant. Each of these solutions provides a different type of benefit, so its return on investment must be calculated differently.
There are, however, several general principles that help us make a realistic calculation. These are exactly what we will examine here.
The investment is not just the cost of the hardware
When people explore self-service systems, they usually first compare the price of the physical devices—a kiosk, terminal, or other necessary hardware. This is understandable because the hardware is the most visible part of the system. A functioning project, however, rarely consists of hardware alone.
Depending on the application, a payment terminal, fiscal device, printer, scanner, specialized tablet, kitchen display, ready-order screen, or other peripheral equipment may be required. Installation, configuration, and integration with the software the business already uses must also be added.
There are also ongoing costs for software, licenses, connectivity, and technical support. For more unconventional projects, there is sometimes no ready-made solution, making additional development necessary. In some cases, the system has to be created almost from scratch, which changes both the budget and the implementation timeline.
That is why the calculation should start with the total cost of a complete, functioning system, rather than the price of an individual device. If we leave out some of the necessary components, the payback period will appear shorter, but it will not be realistic.
What does the return consist of?
The easiest way to examine return is in three areas: direct cost savings, staff time freed up, and additional revenue.
Direct savings are the easiest to measure. They may come from less manual work, fewer data-entry errors, better control, limiting misuse, or reducing other daily losses. With some systems, a business may be able to operate with a smaller team, but this should not be considered an automatic result of installing a device.
In a fast-food restaurant, for example, a cashier rarely only takes orders. They help customers, monitor the process, prepare products, and respond to problems. If this position is eliminated, the other responsibilities do not disappear. Someone still has to take them on.
More often, the system does not replace the person; it frees up part of their time. The customer enters their own order, while the employee can focus on preparation, service, or tasks that previously remained on the back burner. This time has value, but only if it is used effectively. If the work continues in the old way, the benefit will remain mostly theoretical.
Additional revenue depends on the sector. In a fast-food restaurant, the system may help serve more customers during busy hours, reduce lost sales caused by queues, or increase the average order value. In an automated store or vending solution, the benefit may come from sales outside normal operating hours. In a system for institutional or industrial food service, the effect may be faster service for a large number of people within a short period and better organization of pre-ordered meals.
It is not enough simply to say that a system will increase revenue. We need to know where the increase will come from and how we will measure it.
What does the basic calculation look like?
The simplest formula looks like this:
Payback period = initial investment ÷ net monthly impact
The net monthly impact includes actual cost savings, the value of the freed-up time that is put to use, and additional profit. Ongoing costs for software, maintenance, licenses, and connectivity must be deducted from these amounts.
A sound calculation should not begin with a desired payback period, but with an honest look at the process. What is being done now? How much staff time does it require? Where do errors occur? What will actually change after implementation?
The more specific the answers, the more realistic the forecast will be. If the expected benefits are described only in general terms such as “faster service” or “staff optimization,” they can hardly be included in a reliable calculation.
Benefits that are difficult to put into a spreadsheet
Not every benefit has an immediate monetary value. That does not mean it should be ignored.
A well-chosen system shows customers that the business is developing and looking for more convenient ways to serve them. This can have a positive effect on the establishment’s image and increase trust. Of course, the opposite is also true. A slow, confusing, or unreliable system can drive people away. New technology is not an advantage in itself. It must be fast, easy to understand, and suitable for the place where it is used.
Automation also matters for staff retention. Fewer and fewer people want to spend their entire workday performing the same repetitive actions. Taking and transferring orders, entering the same information, and constantly repeating the same operations are tiring, even when they look easy from the outside.
When the system takes over some of this repetition, the work can become more varied and less demanding. Sometimes this is exactly what helps a business retain an employee who might otherwise look for another job. This benefit is difficult to calculate, but the cost of constantly recruiting and training new people is not insignificant either.
Indirect benefits may also include fewer errors, better reporting, more information about customer behavior, and easier planning. They do not always generate immediate revenue, but they often improve the way the business is managed.
Every system will have its own calculation
A universal calculation would be convenient, but misleading. A kiosk in a fast-food restaurant, a food-service system, cash-handling devices, and various software automations have different costs and provide different types of benefits. For one solution, the main benefit may be time saved; for another, the ability to operate without an employee; and for a third, better control and reduced losses.
That is why this article summarizes the principles. Each subsequent article in the “Self-service in Practice” series, dedicated to a specific system, will include a separate section on its return on investment. We will examine what the investment includes, what ongoing costs it involves, what it saves, and under what conditions it makes economic sense.
We will gradually add links to these articles to this material. This way, everyone can first understand the general logic and then see how it applies to the solution they are interested in.
At SelfService.bg, we believe that a good calculation is not the one that promises the shortest payback period. A good calculation includes all costs, does not exaggerate the benefits, and takes into account how the system will be used in real life.
And when some of the unknowns still cannot be determined, the most sensible place to start is with a conversation. You can contact us for a free initial consultation. We will examine the process you want to automate and help you determine which costs and benefits should be included in your calculation.
