Customer and member portals
Self-service portals with SSO (Microsoft Entra, Google Workspace, Auth0), role-based access, document exchange, GoCardless or Stripe billing views and audit trails, replacing email threads and spreadsheets.
SpikeSecure builds bespoke web applications, customer portals, internal systems and SaaS products for UK SMEs, startups and agencies from Coimbatore, India: a fixed-scope proposal in GBP, a five-hour live overlap every UK morning, deployment to AWS London in your account, UK GDPR-led design, and source code and IP that are yours from day one.

SpikeSecure Technologies Pvt. Ltd. is a software development company in Coimbatore, India, that builds bespoke software for UK companies remotely: web applications on Next.js and NestJS, customer and member portals, workflow and back-office systems, multi-tenant SaaS and AI features. UK clients choose between a fixed-scope project with one written GBP price and dated milestones, or a dedicated team of named developers working from your roadmap month to month.
The UK is the international market where our working day fits best: 09:30–18:30 IST is 05:00–14:00 BST, so every UK morning is live with the team for stand-ups, demos and same-day fixes. Deployments go to AWS London (eu-west-2) in accounts you own, integrated with Stripe, GoCardless, Xero, Sage, QuickBooks or HubSpot as your stack requires, and designed for UK GDPR from the first data model.
Self-service portals with SSO (Microsoft Entra, Google Workspace, Auth0), role-based access, document exchange, GoCardless or Stripe billing views and audit trails, replacing email threads and spreadsheets.
Approvals, scheduling, job management, stock and reporting systems for operations teams, integrated with Xero, Sage, QuickBooks Online, HubSpot or your ERP through documented APIs, with Making Tax Digital left to the accounting platform.
Tenant isolation, Stripe Billing or GoCardless subscriptions with VAT handling, usage metering, admin consoles, API keys and webhooks, and UK GDPR controls (records of processing, retention, data-subject request tooling) built into the product.
Two-way sync with Stripe, GoCardless, Xero, Sage, QuickBooks, HubSpot, Companies House, Royal Mail and Slack; Open Banking data through TrueLayer where your product needs it; scheduled jobs and event-driven queues.
Retrieval-augmented assistants over your documents, classification and extraction, summarisation and recommendations using Claude or OpenAI models through your own API keys, with UK or EU data residency respected and evaluation sets and guardrails in place.
Rebuilding legacy .NET, PHP, Access or spreadsheet-driven systems on a modern stack in phases, with data migration, parallel running and a documented cut-over plan rather than a big-bang switch.
UK buyers of bespoke software usually compare a domestic agency, an Eastern European nearshore team and an Indian offshore team. The honest trade-offs: a UK agency shares your hours and your legal system; a nearshore team shares most of your day; an Indian team shares your whole morning, costs a fraction, and in our case comes with a fixed written scope, a warranty and GBP invoicing rather than open-ended time-and-materials.
Our 09:30–18:30 IST day is 05:00–14:00 BST (04:00–13:00 GMT), so every UK working morning overlaps live for stand-ups, demos and same-day fixes; afternoon requests are picked up first thing the next IST morning. UK clients tell us the morning overlap is enough for every decision that needs a conversation; everything else is written down in a shared channel and a Friday status note.
Stripe for cards and wallets, GoCardless for Direct Debit under the Bacs scheme, Open Banking payments through TrueLayer where a bank transfer beats card fees; Xero, Sage or QuickBooks Online for the books with Making Tax Digital handled by the accounting platform. We build the integration and reconciliation; your accountant defines the VAT rules.
We design for UK GDPR and the Data Protection Act 2018 (lawful basis, data-subject rights, records of processing, breach handling), ICO registration where your processing requires it, PECR for cookies and marketing consent, WCAG 2.1 AA for public-sector or accessibility-regulated sites, PCI DSS scope kept inside Stripe or GoCardless, and FCA rules where the product touches regulated payments or lending, at the time of writing (September 2026). Your counsel or DPO signs off; we implement.
AWS eu-west-2 (London), Google Cloud europe-west2 (London), or Vercel with a UK or EU region, in your accounts with your billing; encrypted Postgres, S3 and a CDN in front. Data stays in the UK or EU unless you choose otherwise.
A mutual NDA, then a fixed-scope proposal under a master services agreement you can review with your solicitor; IP assignment to you on payment; GBP invoicing through Stripe or Wise; no UK entity, so no UK VAT is charged by us and your accountant advises on reverse-charge treatment.
One written GBP price for a defined scope, paid in milestones (typically 30% on start, 40% at design sign-off, 30% at launch). Change requests are quoted before they are built.
Monthly rate per developer or designer by seniority, minimum three months, with a project lead included above three people. Scale up or down with 30 days' notice.
Custom software and web applications ₹3–25 lakh on our published Indian pricing, roughly GBP 2,500–22,000 (indicative conversion, roughly ₹115 per pound). Portals and internal tools sit at the lower end, multi-tenant SaaS and modernisation programmes at the upper end.
Quoted and invoiced in GBP through Stripe or Wise, or in INR if you prefer; the fixed price is set in the invoicing currency. We are an Indian entity and charge no UK VAT; your accountant advises on reverse-charge treatment.
Discovery in week 1, a proposal within 48 hours of the last discovery session, design in weeks 2–3, and a build of 8–20 weeks with a pilot release before the full scope where possible.
Number of user roles and integrations, UK GDPR and accessibility work, data migration from legacy systems, AI features, and whether you want a dedicated team after launch.
Read how we choose between stacks on the technologies page.
Scheduled around the agreed UK overlap window; every step is written into the proposal.
Two or three video sessions in the agreed UK overlap window under a mutual NDA, mapping users, integrations and constraints; a fixed-scope written proposal follows, usually within 48 hours of the last session.
Wireframes, a design system and a clickable prototype reviewed with your stakeholders before any code is written.
Weekly demos on a staging URL, GitHub access from day one, a written Friday status note and a shared channel for questions.
Functional, performance, accessibility and security testing against a pre-launch checklist you sign off in writing.
Deployment to AWS London (eu-west-2), Google Cloud London, or Vercel, in accounts you own, monitoring and backups configured, and a launch-week watch with you.
30-day warranty, then optional maintenance with monthly reports, or a documented handover to your team.
Signed before any brief is shared, on your template or ours; no sub-contractors without written consent.
Repositories, cloud accounts, app store listings, domains and design files are created in your name; we hold no licence over the delivered work.
HTTPS with HSTS, security headers, OWASP Top 10 review, role-based access, encrypted secrets, audit logs, dependency scanning and a penetration test before launch on client-facing systems.
We design for UK GDPR and the Data Protection Act 2018 (lawful basis, data-subject rights, records of processing, breach handling), ICO registration where your processing requires it, PECR for cookies and marketing consent, WCAG 2.1 AA for public-sector or accessibility-regulated sites, PCI DSS scope kept inside Stripe or GoCardless, and FCA rules where the product touches regulated payments or lending, at the time of writing (September 2026). Your counsel or DPO signs off; we implement.
Core Web Vitals targets, WCAG 2.1 AA checks, and SEO and AEO fundamentals (clean URLs, structured data, llms.txt) built into every web deliverable.
Documentation, infrastructure as code, tested backups and a recorded handover, so a UK team or another vendor can take over without us.
SpikeSecure has one office, at CHIL SEZ IT Park, Saravanampatti, Coimbatore, India. UK clients are served remotely by that engineering team; there is no UK office, entity or local staff, and we do not claim one.
Our published Indian range is ₹3–25 lakh per project, roughly GBP 2,500–22,000 as an indicative conversion (roughly ₹115 per pound); the written GBP proposal fixes the price. A customer portal or internal tool usually lands in the lower half, a multi-tenant SaaS or a legacy modernisation in the upper half. Dedicated developers are quoted per month by role.
Our 09:30–18:30 IST day is 05:00–14:00 BST (04:00–13:00 GMT), so every UK working morning overlaps live for stand-ups, demos and same-day fixes; afternoon requests are picked up first thing the next IST morning. Weekly demos are held in that window, the Friday status note lists decisions needed, and urgent production issues are handled outside it under the maintenance agreement.
Yes. These are the integrations UK clients ask for most, alongside Stripe, QuickBooks Online and Companies House lookups. We set them up in your own accounts through the vendors' documented APIs and webhooks, tested in their sandboxes before go-live; Making Tax Digital submissions stay with the accounting platform.
We design for UK GDPR and the Data Protection Act 2018 from the data model up: lawful-basis and consent records, data-subject access and erasure tooling, retention schedules, records of processing, breach-handling workflows, encryption and audit logs, hosted in AWS London or another UK or EU region you choose. We are not a law firm; your DPO or solicitor signs off, we implement.
Yes. A mutual NDA, then a master services agreement and a fixed-scope statement of work you can review with your solicitor; governing law and dispute clauses are agreed in the MSA. IP in the delivered work is assigned to you on payment and code sits in your GitHub organisation throughout.
Yes: see ecommerce development for UK brands; mobile apps for UK clients are scoped from the mobile app development page with GBP invoicing and the same delivery model. Real-time products build on the stack behind Local Friends; see video calling app development.

You do. Source code goes into a GitHub organisation in your name; AWS, Stripe, GoCardless, app store and domain accounts are yours from day one; the intellectual property in the delivered work is assigned to you in the proposal.
A 30-minute discovery call and a fixed-scope quote — usually within 48 hours. No deck, no sales theatre.
