Customer and partner portals
Self-service portals with SSO (Okta, Auth0, Google Workspace, Microsoft Entra), role-based access, document exchange, billing views and audit trails, replacing email threads and spreadsheets.
SpikeSecure builds web applications, customer portals, internal tools and SaaS products for US startups and small and mid-sized businesses from Coimbatore, India: a fixed-scope proposal in USD, a daily live window in your morning, deployment to AWS US regions in your account, 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 custom software for US companies remotely: web applications on Next.js and NestJS, customer and partner portals, workflow and back-office systems, multi-tenant SaaS and AI features. US clients choose between a fixed-scope project with one written price and dated milestones, or a dedicated team of named developers working from your roadmap month to month.
What is different from a US agency is the cost base and the time-zone shape, not the engineering: our published Indian ranges are the starting point for every USD proposal, the live overlap is a two-hour window in your morning with the rest handled in writing, and deployments go to AWS or Google Cloud US regions in accounts you own, integrated with Stripe, QuickBooks Online, HubSpot or Salesforce as your stack requires.
Self-service portals with SSO (Okta, Auth0, Google Workspace, Microsoft Entra), role-based access, document exchange, billing views and audit trails, replacing email threads and spreadsheets.
Approvals, scheduling, dispatch, inventory and reporting systems for operations teams, integrated with QuickBooks Online, HubSpot, Salesforce or your ERP through documented APIs.
Tenant isolation, Stripe Billing subscriptions with Stripe Tax for state sales tax, usage metering, admin consoles, API keys and webhooks, SOC 2-style controls documented so your own audit is easier later (we do not hold the certification).
Two-way sync with Stripe, QuickBooks Online, HubSpot, Salesforce, Slack, Twilio, SendGrid and Plaid; Zapier or Make where a connector is cheaper than code; 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 evaluation sets and guardrails.
Rebuilding legacy .NET, PHP or Access systems on a modern stack in phases, with data migration, parallel running and a documented cut-over plan rather than a big-bang switch.
US buyers of custom software are usually choosing between a domestic agency, a Latin American nearshore team and an Indian offshore team. The honest trade-offs: a domestic team shares your hours; a nearshore team shares most of them; an Indian team shares two of them but costs a fraction and, in our case, comes with a fixed written scope and a warranty rather than open-ended time-and-materials.
Our 09:30–18:30 IST day is 00:00–09:00 Eastern and 21:00–06:00 Pacific, so we agree a daily live window (typically 07:00–09:00 Eastern) and keep the rest asynchronous in writing. Decisions are made in that window; everything else is written down in a shared channel and a Friday status note, which US clients tell us removes more ambiguity than another meeting would.
Stripe is the default for US products, with Stripe Billing for subscriptions and Stripe Tax or Avalara for state-by-state sales tax; ACH through Stripe or Plaid where you need bank debits; QuickBooks Online for the books. We build the integration and reconciliation; your accountant defines the tax rules.
There is no single federal privacy law at the time of writing (September 2026); we design for the California CCPA/CPRA and the similar state laws (consent, access and deletion requests, do-not-sell links), HIPAA safeguards when health data is involved (BAA-backed hosting, audit logs, encryption), COPPA for under-13 audiences, PCI DSS scope kept inside Stripe, ADA-driven WCAG 2.1 AA accessibility, and CAN-SPAM and TCPA rules for email and SMS. Your counsel signs off; we implement.
AWS us-east-1 (N. Virginia) or us-west-2 (Oregon), Google Cloud Iowa or Oregon, or Vercel, in your accounts with your billing; RDS or managed Postgres, S3 with encryption at rest, CloudFront or Cloudflare in front. Data stays in US regions unless you choose otherwise.
A mutual NDA, then a fixed-scope proposal under a master services agreement you can review with your counsel; IP assignment to you on payment; USD invoicing through Stripe or Wise; no US entity, so no US sales tax is charged by us.
One written USD 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 USD 3,500–29,000 (indicative conversion, roughly ₹87 per US dollar). Portals and internal tools sit at the lower end, multi-tenant SaaS and modernisation programmes at the upper end.
Quoted and invoiced in USD 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 US sales tax; your accountant advises on any use-tax 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, compliance work (HIPAA safeguards, SSO, audit logging), 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 USA overlap window; every step is written into the proposal.
Two or three video sessions in the agreed USA 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 US East or US West, Google Cloud 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.
There is no single federal privacy law at the time of writing (September 2026); we design for the California CCPA/CPRA and the similar state laws (consent, access and deletion requests, do-not-sell links), HIPAA safeguards when health data is involved (BAA-backed hosting, audit logs, encryption), COPPA for under-13 audiences, PCI DSS scope kept inside Stripe, ADA-driven WCAG 2.1 AA accessibility, and CAN-SPAM and TCPA rules for email and SMS. Your counsel 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 US team or another vendor can take over without us.
SpikeSecure has one office, at CHIL SEZ IT Park, Saravanampatti, Coimbatore, India. US clients are served remotely by that engineering team; there is no USA office, entity or local staff, and we do not claim one.
Our published Indian range is ₹3–25 lakh per project, roughly USD 3,500–29,000 as an indicative conversion (roughly ₹87 per US dollar); the written USD 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 00:00–09:00 Eastern and 21:00–06:00 Pacific, so we agree a daily live window (typically 07:00–09:00 Eastern) and keep the rest asynchronous in writing. Weekly demos are recorded, the Friday status note lists decisions needed, and urgent production issues are handled outside the window under the maintenance agreement.
Yes. These are the integrations US clients ask for most, and we set them up in your own accounts through the vendors' documented APIs and webhooks, tested in their sandboxes before go-live. The same checkout, ledger and payout pattern already runs in production on Razorpay in Local Friends and our published case studies.
We build to HIPAA's technical and administrative safeguards: BAA-backed hosting (AWS signs BAAs), encryption in transit and at rest, role-based access, audit logs, session controls and breach-notification workflows, documented for your compliance officer. Compliance is your organisation's status, not a certificate we hold; your counsel 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 counsel; 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, so you are never dependent on us to keep it.
Yes: see mobile app development for US companies and ecommerce development for US brands. Real-time products (video calling, live rooms, party and social apps) build on the stack behind Local Friends; see video calling app development.
In Coimbatore, India. SpikeSecure has no US office or entity; your project is delivered remotely under a mutual NDA, with a daily live window in your morning (typically 07:00–09:00 Eastern), recorded weekly demos on a staging URL and written status notes for everything else.
You do. Source code goes into a GitHub organisation in your name; AWS, Stripe, Apple, Google Play 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.
