SaaS vs bespoke software: which offers better long-term value?
SaaS is often the right choice for small teams and standard processes. But as your business grows, per-user pricing, workarounds and unused functionality can start to make bespoke software look far more attractive.
In the AI-assisted development era, custom software can often be designed, built and tested faster than many business owners expect — while still being tailored around your exact workflows, reports, permissions and business rules.
Bespoke may suit you if...
- Licence costs are rising
- Staff use spreadsheets around SaaS
- You pay for features nobody uses
- Reporting requires manual exports
- Your workflow is unique to your business
SaaS is often the correct starting point
Off-the-shelf SaaS products can be excellent. They are quick to deploy, usually require minimal setup and often solve common business problems very well.
SaaS is usually a good fit when:
- You need something immediately
- Your processes are fairly standard
- You have a small number of users
- You do not need much customisation
- You are happy to adapt your process to the software
The question is not whether SaaS is good or bad. The real question is whether it still provides the best value once your team, processes and reporting requirements become more complex.
Where SaaS pricing can start to add up
Many SaaS systems charge per user each month. The monthly figure can look modest, but the total cost over several years can become significant, especially for operations-heavy businesses where office staff, managers, supervisors, inspectors and field staff all need access.
10 users
£15k
Approx. 5-year cost at £25/user/month
25 users
£37.5k
Approx. 5-year cost at £25/user/month
40 users
£60k
Approx. 5-year cost at £25/user/month
50 users
£75k
Approx. 5-year cost at £25/user/month
Figures are illustrative only. Actual SaaS pricing varies by supplier, package, user type, modules, support level and contract terms.
AI has changed the economics of bespoke software
In the past, bespoke software was often dismissed as too slow or too expensive for many SMEs. A large part of development time was spent on repetitive coding, form creation, documentation, testing and boilerplate work.
Modern AI-assisted development tools such as ChatGPT and Anthropic Claude can significantly reduce the time needed to design, code, test and refine a custom business application.
The result is that bespoke software can now be more practical for SMEs — especially when guided by an experienced developer who understands security, databases, integrations and long-term maintainability.
Where AI can help reduce build time
- Rapid prototyping
- Form and screen scaffolding
- Boilerplate code generation
- Workflow documentation
- Test case creation
- Refining existing spreadsheet logic
Real-world example: operations software for a growing contractor
Consider a contractor or field-service business where access may be needed by:
- Operations managers
- Contracts managers
- Administrators
- Yard or warehouse staff
- Supervisors
- Drivers
- Inspectors
- Directors or senior managers
SaaS subscription route
- 40 users
- £25 per user/month
- £1,000 per month
- £12,000 per year
- £60,000 over 5 years
This excludes possible setup fees, premium modules, API access, SMS charges, storage upgrades or support packages.
Bespoke alternative
- Built around your exact workflow
- No per-user licence fees
- Only the functionality you actually need
- Reporting designed around your business
- System can evolve with your processes
Smaller bespoke projects may start around £10k–£15k, with larger or more complex systems costing more depending on functionality, integrations and migration requirements.
Paying for functionality you never use
Another hidden cost of SaaS is that many businesses pay for a broad platform but only use a small part of it. The software may include CRM, stock control, purchasing, HR, customer portals, asset tracking and reporting modules — even if your team only really needs scheduling, timesheets and job status updates.
Bespoke software works the other way round. You start with the workflow that actually matters, then build the screens, permissions, reports and integrations your business genuinely needs.
Beyond cost: why businesses choose bespoke
Exact workflow fit
The system follows how your business works rather than forcing staff into generic processes.
Better reporting
Management dashboards and reports are designed around the information you actually need.
Fewer workarounds
Reduce spreadsheets, duplicate data entry, manual exports and disconnected side processes.
More control
You control how the system develops, what it connects to and how it supports your business over time.
When bespoke software starts to make sense
- Growing workforce or rising user licence costs
- Multiple SaaS tools that do not quite join up
- Manual reporting or spreadsheet workarounds
- Duplicate data entry between systems
- Specialist workflows not supported properly by SaaS
- Need for better audit trails or permissions
- Frustration with paying for unused functionality
- Long-term system ownership is important
Curious how your current software costs compare?
If you tell me which systems you currently use, how many staff need access and what frustrations exist today, I can provide an honest assessment of whether bespoke software is likely to deliver better long-term value.
