What Is Your Current Software Really Costing You?
Use the NovaStacks ROI calculator to see your projected savings from switching to custom, owned software — no per-seat fees, no unused features, no licence lock-in.
Every month, off-the-shelf software charges you for what you don't use
Most growing UK businesses are running three to five SaaS tools — each billing per seat, per month, with pricing tiers designed to push you into the next bracket. You end up paying for features you have never opened, workarounds to bridge tools that won't talk to each other, and licences for staff who only log in twice a week. The costs compound quietly. The operational drag builds with them.
Custom software built around your process — and owned by you
NovaStacks builds bespoke software on a modern stack (React, TypeScript, Node.js, PostgreSQL) shaped exactly around how your operation runs. No compromises, no workarounds, and no recurring per-seat licence once it is live. You pay to build it, you own the code outright, and your team uses it without a billing meter running in the background.
- No per-seat licensing: a one-off build investment, not a monthly charge per head that scales against you as your team grows
- No paying for unused features: every function in the system earns its place, built precisely for how you actually work
- No lock-in: you own the source code and are never dependent on a single vendor's roadmap, pricing decisions or product sunset
How it works
The calculator takes four inputs: your current monthly SaaS and software spend, the number of staff on paid licences, an estimate of the hours your team spends each week on manual tasks a bespoke system could handle, and an approximate hourly cost for that time. From those figures it produces a three-year cost comparison — what continued off-the-shelf spending looks like versus a one-off custom build with ongoing maintenance — and a projected payback period. Enter your numbers in the tool above, review your output, then send it to us with a brief description of the system you need built or replaced.
Why NovaStacks — proof you can see in production today
NovaStacks runs 15-plus live, supported SaaS products built with exactly the same engineering it applies to every client project. GuardFlowApp is a full security workforce management platform serving SIA-licensed operations across the UK — scheduling, compliance, patrol tracking and incident logging, all purpose-built for the industry. CleanFlow handles cleaning workforce management. FleetFlowApp manages fleet and vehicle-rental operations. CareOps covers care recruitment and compliance. AutoLeadCall handles AI outbound calling and lead qualification. These are not demos or wireframes: they are live, customer-facing platforms maintained by the same team that would build your system. That production track record is the one thing template vendors and solo freelancers cannot replicate. Project investment with NovaStacks averages over £2,000, scoped and supported by one accountable UK team from specification through to long-term maintenance.
Frequently asked questions
How do I know if custom software will actually pay off for a business my size?
The calculator above is designed to answer exactly that question using your real numbers. As a general rule, if five or more people in your business are on paid SaaS seats, or your team is spending several hours a week on manual processes a system could handle, the economics of a custom build tend to work in your favour — particularly once the compounding effect of monthly licence costs is removed from the equation. Run your numbers and the comparison will be plain.
What if our requirements change after the software is built?
Because you own the source code outright, changes are a matter of straightforward engineering work — not a feature request to a vendor who may never prioritise it. NovaStacks provides ongoing maintenance and support as a long-term partnership, so iterating on your system as the business grows is a planned part of the relationship, not a costly exception handled by a stranger who has never seen the codebase.
Can you show us software you have actually built and not just described?
Yes — that is precisely the point of running our own products. GuardFlowApp, CleanFlow, FleetFlowApp, CareOps and more than a dozen other platforms are all live in production, serving real customers today, built on the same stack and maintained by the same team that would work on your project. When you speak to us, we walk you through any of them directly so you can judge the quality of the engineering for yourself before committing.
