What is Bespoke Software?
Bespoke software (also custom software) is software developed individually for your company. Unlike standard software like Salesforce or SAP, it's tailored precisely to your processes, requirements, and workflows.
Typical Examples of Bespoke Software:
- Internal Tools: Workflow management, employee portals, reporting dashboards
- Customer-Facing Apps: Customer portals, mobile apps, e-commerce platforms
- Integration Layers: Connecting different systems
- Industry-Specific Solutions: Healthcare, finance, logistics
- Automation Solutions: RPA, workflow automation
Bespoke vs. Off-the-Shelf Software
When Bespoke is the Better Choice:
| Situation | Recommendation |
|---|---|
| Your process is unique/complex | Bespoke |
| You need competitive advantage | Bespoke |
| No suitable software on the market | Bespoke |
| You need full control over data | Bespoke |
| Long-term investment planned | Bespoke |
When Off-the-Shelf is Better:
| Situation | Recommendation |
|---|---|
| Standard process (CRM, accounting) | Off-the-Shelf |
| Very limited budget | Off-the-Shelf |
| Quick solution needed | Off-the-Shelf |
| No IT resources for maintenance | Off-the-Shelf |
| Proven solution desired | Off-the-Shelf |
5-Year Cost Comparison
| Aspect | Bespoke | Off-the-Shelf |
|---|---|---|
| Initial Costs | £50,000-£300,000 | £5,000-£50,000 |
| Annual License Costs | £0 | £10,000-£100,000+ |
| Customization Costs | Flexible | Often limited/expensive |
| Total Costs 5 Years | £70,000-£400,000 | £55,000-£550,000 |
Important: With long-term use, bespoke can be cheaper since there are no ongoing license costs.
