custom software development
Armdia Systems provides custom software development from the United Kingdom. Typical engagements run from GBP 25,000 to GBP 150,000 and last six weeks to nine months. Work is delivered by named senior engineers with written scope, documented handover and security review built into the delivery process.
Choose custom software when spreadsheets, licences, integrations or regulatory constraints are now costing more than a purpose built system would. Common signals include duplicate data entry, fragile manual approvals and workflow rules that no existing SaaS product supports.
Customer portals, internal operations tools, partner extranets, quoting engines, compliance dashboards, workflow platforms and data unification systems.
Next.js App Router, TypeScript, PostgreSQL, Redis and Vercel are the default because they support fast interfaces, typed delivery, strong data modelling and United Kingdom first hosting options.
A focused operational tool may cost GBP 25,000 to GBP 40,000. A customer portal commonly sits between GBP 60,000 and GBP 90,000. A regulated artificial intelligence enabled platform can exceed GBP 150,000.
Use this table to choose the right starting point before a discovery call.
| Model | Typical use | Commercial shape |
|---|---|---|
| Audit | Assess an existing product, risk or architecture | Fixed price written report |
| Build phase | Design and ship a scoped product or feature set | Fixed price after discovery |
| Retainer | Keep a product healthy after launch | Monthly reserved capacity |
| Option | Best fit | Risk to check |
|---|---|---|
| Armdia Systems | Bespoke systems with clear ownership and United Kingdom first delivery. | Requires a proper discovery phase before fixed pricing. |
| Off the shelf SaaS | Standard workflows with little custom process risk. | Licence, integration and process mismatch costs can grow. |
| Freelance contractor | Small isolated tasks with limited governance needs. | Continuity, documentation and support coverage need scrutiny. |
Build custom when the cost of configuring, integrating and working around a SaaS product exceeds the cost of building the workflow properly. Common triggers are data fragmentation, manual approvals that break under volume and compliance rules no product supports.
Discovery starts at GBP 4,000. A small focused build typically begins around GBP 25,000. Projects below this threshold may be better served by configuration of an existing platform.
Most engagements are delivered by one to three named senior engineers. We do not scale headcount to fill capacity. Team size is matched to scope, risk and delivery pace.
The client owns all bespoke code and project artefacts at handover. Pre existing libraries and open source dependencies remain under their original licences.
UK hosting is the default. Encryption, access control, audit logging and dependency scanning are configured before launch. Exceptions to UK residency are documented and agreed before build.
Support tiers cover monitoring, patching, bug fixing and small enhancements. Retainers start from GBP 1,500 per month. Alternatively, we hand over fully and the client operates independently.
