Stop Buying Tools. Build Them.

Stop renting generic SaaS and paying per user. AI has changed the economics of software. Learn when to buy and when to build custom business software.

For decades, businesses have been conditioned to accept a compromised reality. We find a generic software service. We rent seats for our team. We adapt our distinct operational processes to fit someone else's idea of how work should be done. Then, when we need something to work differently, we submit a feature request and wait for a vendor roadmap to catch up.

I am Justin Trantham, CEO of FlowDevs. We Build the Applications Your Business Runs On. We have watched companies spend fortunes on software that dictates their operations rather than supporting them. The traditional calculus of buy versus build software is dead. AI-assisted development has fundamentally rewritten the economics of software engineering. Today, before your company automatically buys another monthly subscription, you must ask whether that specific workflow is important enough, specific enough, and simple enough to build as owned software.

The Generic Software Problem

Consider the modern enterprise architecture. We pile platforms on top of platforms. Each platform comes with its own rigid data structures and workflow assumptions. You are renting access to a generalized solution built to satisfy the average needs of thousands of different companies.

Microsoft Dynamics 365 Sales Enterprise is a fantastic example of a standard powerhouse. At FlowDevs, we are a Microsoft-first business. We use Microsoft products heavily and recommend them often. Dynamics is a profoundly capable system. Looking at current list prices, Dynamics 365 Sales Enterprise runs about $105 per user per month when paid yearly. Prices are always subject to change, but this establishes the baseline for enterprise software today.

Dynamics is highly configurable and extended by a massive ecosystem. You can mold it to do almost anything. But at the end of the day, you remain a tenant in someone else's building. The core changes to the product and the strategic direction of the platform remain entirely under Microsoft's control. You are chained to a standard vendor roadmap.

Building Our Custom CRM

When FlowDevs needed a system to manage our client relationships, we faced a choice. We could easily default to renting a conventional CRM. Instead, we chose to write our own. We built a custom CRM using Lovable.

This is not a toy or a simple spreadsheet replacement. It is normal, production-ready software backed by owned code. The entire repository lives in GitHub, fully under our control. Furthermore, we designed it with an MCP layer. This Model Context Protocol layer allows compatible AI clients to interact securely and directly with our CRM system.

The strongest advantage we have experienced is not the subscription savings. The true advantage is ownership, speed, and absolute adaptability. Creating a Lovable CRM shifted the power dynamic inside our company.

Traditionally, if a salesperson wanted a new feature, they filed a ticket with IT. Now, the people closest to the work have the power to improve the tool. At FlowDevs, our Client Director, our Principal Engineer, our CTO, and myself have all directly contributed to improving this CRM. Team members who did not originally write the base code are actively iterating on the product. AI app development has lowered the barrier to entry, allowing the actual subject matter experts to shape the tools they use daily.

The Cost of Ownership

Let us look at a practical cost example to illustrate why per-user SaaS pricing is ripe for disruption. Imagine a small sales team of ten users.

For ten users, the list price of Dynamics 365 Sales Enterprise is roughly $1,050 per month. That figure represents just the base licensing. It does not include the heavy implementation fees, the required external integrations, or any premium feature add-ons a business might require over time.

Conversely, look at the baseline software we used to generate our system. Lovable Pro currently starts at $25 per month for a shared workspace. That tier includes unlimited members and 100 monthly credits. Because Lovable charges around a shared credit pool rather than charging per seat, you stop paying penalties for simply adding a new user to your system. Note that credit consumption naturally varies depending on task complexity, and not all AI model tokens cost the same amount.

I must state clearly that this is not a perfect apples-to-apples comparison. It would be foolish to pretend a $25 monthly workspace instantly replaces every facet of a legacy enterprise CRM. Dynamics includes mature enterprise capabilities, rigorous out-of-the-box governance, global support structures, and a very large third-party ecosystem.

Real production costs for custom software always go beyond the generation tool. When you build custom business software, you also pay for dedicated hosting, database management, integration platforms, security hardening, user support, and additional AI generation credits.

The point is not that a small monthly fee replaces an enterprise system. The point is to challenge the automatic reflex of per-seat purchasing. SaaS pricing models punish adoption. The more successful a tool is inside your company, the more expensive it becomes to maintain. Building limits those arbitrary usage taxes.

Do not build everything

Am I telling you to abandon all SaaS products and code every system from scratch? Absolutely not. Choosing when to buy versus build software requires discipline.

There are many scenarios where buying is the far smarter choice. You should always buy commodity functions that offer no distinct operational advantage. You should buy highly regulated systems, such as mature accounting packages or payroll software, where compliance dictates the feature set.

Furthermore, if your organization has limited internal ownership capability, you should rent. If you lack the discipline to manage a product long-term, custom software will become technical debt. If you have a weak security capability and cannot responsibly protect your own data infrastructure, you have no business building custom operational tools.

A Framework for Decisions

Before you sign another software contract, you need to evaluate the workflow in question. We use a clear decision framework built around five crucial questions.

Is this workflow a competitive advantage?

If the process is a standard industry practice, buy the standard tool. If the way you manage this data or interact with your clients is unique and drives your business success, that workflow belongs in software you completely own.

Are we paying for many features we do not use?

Enterprise SaaS solutions bloat over time. Vendors add features to justify price increases, forcing you to pay for complex modules your team will never deploy. If you only need ten percent of a system, bespoke development might prove significantly cheaper over a multi-year timeline.

Does per-seat pricing punish adoption?

You want your entire company to have visibility into core operations. When every viewer requires an expensive monthly license, businesses start sharing logins or keeping users out of systems entirely. Owned software empowers you to grant access safely without triggering new invoices.

Do we need changes faster than the vendor roadmap?

If a critical market shift happens, you cannot wait eighteen months for a major software provider to update their application. Having your own code means your team can push new features to production on the exact day you need them.

Can we responsibly own security, maintenance, and support?

Ownership comes with responsibility. You must be prepared to govern the environment. We do not advocate for every single employee directly editing production code without strict oversight. Proper deployment pipelines, code reviews, and infrastructure security are non-negotiable.

The Challenge

The era of default software renting is ending. The tools to build, iterate, and host powerful bespoke applications are better and more accessible than ever before. It is time to treat your core operational systems as vital company assets.

Before you swipe a credit card for the next big tool, calculate the real cost. Price the cost of building the exact workflow you need. Measure the value of owning the intellectual property and controlling the direction of the product.

Stop buying tools. Build them.
