Why SaaS stacks quietly get expensive

Replace your saas stack with owned software to avoid the hidden costs of per-seat SaaS. Every tool you add increases your spend, and agencies charge for time you don’t use. The cost compounds over time, and you never own the code.

Most companies rent growth: per-seat SaaS subscriptions plus agencies they never stop paying. This model is expensive and inefficient. By replacing your saas stack with owned software, you stop the compounding costs and keep the asset for yourself. The numbers speak for themselves — Shattuck clients have replaced roughly $3,496/mo of SaaS subscriptions with owned tools.

How to audit which tools are worth replacing

Replace your saas stack with owned software by auditing which tools are redundant or costly. Start by listing all your SaaS tools and their costs. Then, identify which ones are overlapping or underused.

A focused audit will show you where your money is going. Tools that are per-seat, have overlapping features, or are used in core workflows are the best candidates for replacement. You can also look for tools that are expensive to maintain or that don’t align with your long-term goals. This audit is the first step in replacing your saas stack with owned software that works for you.

Which subscriptions are cheapest to replace first

Replace your saas stack with owned software by prioritizing high-cost, overlapping, or underused tools. These are the ones that will give you the fastest return on your investment.

Start with tools that are per-seat, have overlapping features, or are central to your acquisition and retention efforts. These are the easiest to replace and the most impactful to remove from your stack. You’ll save the most money quickly, and the process will build momentum for replacing more tools. The key is to focus on the ones that are most expensive and least aligned with your business goals.

What consolidating tools into owned software looks like

Replace your saas stack with owned software by consolidating tools into a single, owned solution. This means building a custom tool that fits your unique workflows and eliminates the need for multiple SaaS subscriptions.

The process starts with a working demo — a 1-Day Build — to show you what the tool can do. From there, you can scope out the full replacement, ensuring that the tool meets your needs without unnecessary complexity. Consolidating tools into owned software means you stop paying for per-seat fees and keep the asset for yourself. This is how you replace your saas stack with something you own and control.

How much recurring spend you can actually recover

Replace your saas stack with owned software to recover recurring spend and stop the compounding costs of per-seat tools. The numbers are real and measurable.

Shattuck clients have replaced roughly $3,496/mo of SaaS subscriptions with owned software, cutting their recurring spend significantly. By replacing your saas stack with owned tools, you stop paying for tools that don’t align with your business and keep the asset for yourself. The savings are real, and the cost stops growing once you own the code.

What to keep on SaaS and never rebuild

Replace your saas stack with owned software, but don’t rebuild everything. Some tools are too specialized or too costly to replace.

Keep tools that are niche, have no overlap with other tools, or are used in a way that’s hard to replicate with custom software. These are the tools that are worth keeping and that you should never rebuild. The key is to replace the ones that are costly, overlapping, or underused, and keep the rest. This way, you maintain efficiency without unnecessary complexity.
