Custom Software or SaaS: How to Avoid Overpaying for a Solution That Isn't Right for You

The company purchases a SaaS subscription for $500 per month. A year later, another one is added—for a different department. Then a third, to integrate the first two. Two years later, the business is paying for five services that partially overlap and that no one can quickly configure to fit the company’s actual processes.

This is a typical scenario. And that’s exactly why the question of «whether to buy something off-the-shelf or build your own» should be decided before signing the first contract, not after.

What SaaS Actually Offers

SaaS is a subscription service. You pay for access, not for the right to customize the product to your needs. The provider decides which features will be added and which will be removed, when the price will go up, and whether support will even be available three years from now.

The main advantage of SaaS is how quickly it can be launched. Sign up, pay, and get started today. For standard tasks—email, video calls, and basic accounting—this is the right choice: the market for these solutions is mature, and your processes are unlikely to differ from those of thousands of other companies.

The hidden problem with SaaS is the total cost of ownership. The monthly price listed on the website rarely reflects actual costs. On top of that, there are fees for integrations, limits on the number of users or transactions, and—most importantly—the time your team spends dealing with a clunky interface that wasn’t designed specifically for your workflow.

What Custom Development Actually Offers

A custom product is built specifically for a company’s unique processes. There are no unnecessary modules that you don’t use, and there are no compromises between «what works best for you» and «what the vendor has created for everyone.».

The myth that custom development is «time-consuming and expensive» dates back to the 2010s. Modern frameworks and off-the-shelf technology platforms have drastically reduced development times. A small, clearly defined tool—such as a customer portal, a production tracking system, or integration between several services—can now be implemented in a matter of weeks, not months.

Custom solutions excel where a company's processes are its competitive advantage. If your approach to working with customers, production, or logistics is unique, forcing it to fit someone else’s template means forcing your competitive advantage itself to fit that template.

A Hybrid Approach—and Why It's Not a Compromise

The most common mistake is to view the choice as an «either-or» situation. In practice, a combination works best: standard processes are handled by off-the-shelf services, while unique ones are addressed by a custom solution that either integrates these services or replaces the single module that isn’t working.

Example: A company uses off-the-shelf CRM software for basic customer management, but is developing a separate module to calculate production costs—because no off-the-shelf product calculates them the way it’s customary in this particular industry.

This is what working with a custom solution means in practice: not replacing the entire stack, but making targeted changes where an off-the-shelf product creates more problems than it solves.

Three Questions to Ask Before Making a Choice

Does the finished 80% product meet the requirements without any modifications? If so, go with SaaS. Spending your budget on a custom solution just for the sake of the last 20% is rarely justified.

Is the cost of SaaS rising faster than the business is growing? Per-user licenses, paid transaction limits, and additional modules available for a separate fee—all of these should be factored in over a three-year period, not just one month.

Is there a process that provides a competitive advantage? If there is one—this particular process shouldn't be tailored to someone else's product.

How it looks in Applic

We translate the client’s vision into a digital format and turn it into a working product—without being limited to a single template or solution. If part of the task can be handled by an off-the-shelf service, we acknowledge that and don’t build anything unnecessary. If a company’s process is unique and no off-the-shelf solution covers it, we develop a product tailored to that specific task.
