Custom Software Development for D2C Brands

SaaS, internal tools, APIs, and mobile apps — built for scale

Growww Tech is an ecommerce agency, not a software company — build is phase two of eight.

Lokshi’s Choice storefront built by Growww Tech

But when a D2C brand needs more than a store, the same team writes the software: B2B SaaS products, internal operations tools, APIs and integrations, cross-platform mobile apps. TypeScript / Node / Python / Flutter, deployed on AWS or Vercel. Fixed-price delivery with proper documentation, testing and handover — not freelancer code that breaks in production.

The ceilings

The ceilings founders hit on this layer

  • Your operations run on spreadsheets that keep breaking

    Inventory in one sheet, orders in another, team schedules in a third. It worked at 50 orders/month. At 500 it's chaos. You need a proper internal tool but don't know who builds them.

  • You have a SaaS product idea but no technical co-founder

    You know the market. You've validated demand. But you don't code, and every dev you've talked to either quotes ₹50L or disappears after the first payment. You need a partner who ships, not a freelancer who experiments.

  • Your existing software doesn't talk to anything

    Your Shopify store, your CRM, your accounting tool, your WhatsApp business — all separate silos. Data gets re-entered manually. Mistakes compound. You need APIs and integrations that close the loops.

  • Your team is stuck on manual work that software could automate

    Order reconciliation, customer onboarding, report generation, invoice processing — hours of manual work every week. A simple dashboard or workflow tool would save 20+ hours/week, but it never gets prioritised.

  • Your internal tool was built 3 years ago and nobody can maintain it

    The original developer left. The code is undocumented. The database schema lives in someone's head. Every change is risky. You need a modernisation, not a rewrite you can't afford.

  • You can't find devs who ship production-ready code

    Freelancers build prototypes, not products. Agencies quote enterprise prices. In-house hires take 6 months and may leave. You need a team that delivers tested, documented, production-ready software — on budget.

What we build for you

Here's what changes once we're done.

B2B SaaS Products

Multi-tenant SaaS with auth, billing, team management, admin dashboards. Stripe / Razorpay subscriptions, usage-based billing, enterprise-ready from MVP. TypeScript + Next.js + PostgreSQL stack by default.

Internal Tools + Dashboards

Custom internal tools that replace spreadsheet workflows. Inventory management, operations dashboards, order-reconciliation, custom CRMs. Retool-style admin panels when speed matters; full custom when the workflow is complex.

APIs + Integrations

REST + GraphQL APIs for your existing products. Shopify + CRM + accounting + payments — integrated into a single workflow. Webhook-driven architecture, proper API documentation, versioning from day one.

Cross-Platform Mobile Apps

Flutter for iOS + Android from one codebase. Native performance, push notifications, deep linking, offline sync. App Store and Play Store submission included.

AWS / Vercel Deployment

AWS (ECS, Lambda, RDS, S3) for compute-heavy or data-heavy workloads. Vercel for Next.js front-ends and serverless APIs. CI/CD pipelines with GitHub Actions. Zero-downtime deployments.

How we deliver

The process, step by step

  1. Discovery + NDA

    30-min discovery call. Understand the business problem, not just the technical ask. Sign NDA if you've sent one. No sales pitch.

  2. Scoping Sprint

    1-2 week paid scoping sprint for non-trivial projects. Output: MVP feature list, architecture diagram, fixed-price quote, milestones, delivery timeline. You decide whether to proceed with full build.

  3. Design + Architecture

    UX design in Figma for customer-facing interfaces. Technical architecture docs for the engineering team. Database schema, API contracts, deployment topology — documented before code starts.

  4. Build in Sprints

    2-week sprints with weekly demos. Working software shipped to staging at every sprint end. You see progress, flag issues early, steer direction. No black-box development.

  5. Testing + Launch

    Automated tests (unit + integration + E2E). Load testing for performance-critical features. Security audit before public launch. Staged rollout with monitoring.

  6. Handover + Retainer

    Complete code handover, documentation, credentials, and runbook. 30 days of bug-fix support included. Optional retainer from ₹50K/month for ongoing development or you take it in-house — your call.

Price and terms

How the price is set

We quote custom software on the 30-minute call, once we know the job it has to do and who will use it. You get one price for the agreed scope, fixed in writing before any work starts.

  • Quoted on a 30-minute call, for your store and your scope.
  • Fixed for the agreed scope, in writing, before work starts.
  • Every price is + GST. You get a GST invoice from Grovesbox Private Limited (GSTIN 37AAKCG0804D1ZZ) after every payment.
  • Refunds work exactly as our terms say. Read the refund terms

What clients say

“I was initially worried about the technical side of moving our business online, but the team at Growww Tech made it seamless.”

They were incredibly patient, explained every step of the backend process, and bridged the language barrier effortlessly. The automation tools they set up for WhatsApp have saved us hours of work. A fantastic partner for any growing business.

Fit check

Who this is for, and who it is not

This is for you if

  • Your operations or your product need software no Shopify app gives you: a seller panel, a POS, returns, integrations.
  • You want one price for the agreed scope, fixed in writing.

Not for you if

  • A job a Shopify app already does. We will say so on the call.
  • You are a student or looking for a job. See our open roles and our programs.
  • The budget does not fit yet. Start free with the Growww↗ app, the 344-point CRO checklist and the full Shopify cost breakdown for India.
  • Running an agency? We take white-label and sub-contract work for agencies. Book a strategy call and tap “I’m an agency or developer”.

FAQ

Commonly asked

No. We’re not a Shopify dev shop. We’re not a tech company. We’re operators who build, optimise, and run the commerce stack behind 200+ Indian D2C brands — the ecommerce agency that runs the whole operation, eight phases from foundation to enablement. Custom software is one layer of that stack: when a brand needs an internal tool, an integration or a SaaS product, the same team that runs its store builds it. A listed Shopify Partner, based in Visakhapatnam.

Four main categories: (1) B2B SaaS products — subscription platforms, multi-tenant dashboards, APIs. (2) Internal tools — inventory management, operations dashboards, workflow automation, custom CRMs. (3) APIs + integrations — connecting Shopify, CRMs, accounting, payment systems. (4) Cross-platform mobile apps with Flutter. All fixed-price, all with full handover at the end.

TypeScript / Node.js for backends. React + Next.js for web front-ends. Flutter for mobile (iOS + Android from one codebase). Python for data-heavy services and ML work. PostgreSQL / MongoDB for databases. AWS (ECS, Lambda, RDS) or Vercel for deployment. We pick the tools that fit the project, not the ones we prefer.

Entry-level internal tool / dashboard: ₹5,00,000–₹10,00,000. Mid-scope SaaS MVP: ₹12,00,000–₹25,00,000. Full B2B SaaS with multi-tenancy, billing, admin, APIs: ₹25,00,000–₹60,00,000. Enterprise custom software: ₹50L+. All fixed-price with milestone payments; no hourly billing that balloons.

12-16 weeks for an MVP with 3-5 core features, auth, billing, and a clean admin. 20-28 weeks for a production-ready B2B SaaS with multi-tenancy, team management, and rich dashboards. Every project starts with a scoping sprint that nails the MVP feature list — we don't build everything; we build what your first 100 customers need.

You do. From day one. Complete source code, documentation, deployment credentials, and database access all belong to you. We sign an IP-assignment clause in every contract. No vendor lock-in, no hostage data, no "we own the framework" excuses. Standard practice.

Yes. Send your NDA to sales@growwwtech.com ahead of the first call. We'll sign before any specifics are discussed. Most founders don't request one and prefer to keep the first call exploratory — both paths are fine.

Yes. 30 days of bug-fix support included. Retainers from ₹50,000/month for ongoing development (new features, integrations, support). Or you can take it in-house — we hand over complete code, documentation, and CI/CD so your team can run it independently.

GDPR and India's DPDP Act compliance are standard in every build — data encryption at rest and in transit, user consent flows, data deletion rights, audit logs. SOC 2 Type II and HIPAA require specific infrastructure and processes we scope upfront for regulated industries. Not every project needs them; we advise honestly.

Yes. Standard integrations include Shopify (Admin + Storefront APIs), HubSpot, Salesforce, Zoho, Tally, QuickBooks, Razorpay, Stripe, Segment, and Twilio. Enterprise integrations (SAP, Oracle, custom ERPs) handled as scoped add-ons with longer timelines. Webhooks, REST, and GraphQL all supported.

Three reasons: (1) Fixed-price delivery — big IT services companies bill hourly and projects routinely balloon 2-3x. (2) Small senior team — your project gets 2-3 experienced engineers, not 10 junior devs managed by an offshore PM. (3) Production focus — we ship tested, documented, monitored software that your team can actually maintain, not "works on the developer's machine" prototypes.
