A useful estimate begins with the requirements
There is no reliable universal price for custom software. Two systems that appear similar on the surface can differ enormously in business rules, integrations, data quality, access permissions and testing requirements.
For this reason, a responsible supplier normally distinguishes between an early broad estimate and a formal quotation based on documented scope.
InfoForte generally considers bespoke development projects with budgets starting from £30,000 or equivalent. This is a qualification threshold, not a promised price for any particular system.
The main factors affecting development cost
Functional scope
The number and complexity of workflows, roles, screens, reports and business rules all affect effort. Exceptions often take more analysis than the obvious happy-path process.
Integration requirements
Connecting external systems may involve API limitations, authentication, data transformation, error handling and testing across suppliers.
Data migration
Replacing an old system may require extraction, cleanup, mapping, reconciliation and repeated migration rehearsals.
Security and permissions
Different roles, sensitive information and audit needs must be designed and tested appropriately. The cost depends on the actual risk profile and business use.
Testing and acceptance
Testing must cover real workflows, calculations, exceptional cases and agreed acceptance criteria. A shorter build estimate that omits these steps can be misleading.
Deployment and ongoing support
Hosting, monitoring, maintenance, future enhancements and support arrangements should be evaluated separately from the initial development quote.
Why very early fixed quotes can be unreliable
A supplier can quote confidently only where the requirements and assumptions are sufficiently clear. If a price is fixed after a short introductory call, the number may contain hidden exclusions or lead to substantial changes later.
A more transparent method is to provide a broad budget range first, then complete defined discovery before setting out price, scope and responsibilities.
What paid discovery should achieve
The outcome is a useful written development plan: objectives, users, essential features, principal workflows, integrations, assumptions, risks and indicative milestones. This helps the customer make a genuine purchasing decision and compare suppliers on a more consistent basis.
Think about the commercial return
Cost alone is not the purchasing decision. Consider hours saved, errors avoided, revenue otherwise lost, exposure to failing legacy systems and the value of a process that better supports the business. Use defensible estimates, not promised ROI percentages.
Avoid false economy
The cheapest bid may omit important testing, documentation, data migration or support. Compare scope, exclusions, acceptance criteria, delivery process and intellectual-property terms before comparing the headline total.
Practical next step
Start with a clear description of the problem and an approximate investment range you can support. A free initial discussion can establish whether detailed scoping is worthwhile.
