SaaS Development · Shopify Native

Build the product. Not just another app shell

Multi-tenant SaaS products for Shopify merchants and the wider commerce ecosystem. We design and ship subscription platforms, B2B tools and marketplace-ready products with auth, billing, tenancy and observability built in — so you can sell, scale and retain without re-architecting after the first hundred customers.

Where SaaS ROI leaks

Where founders waste budget on SaaS products, and what we fix

Eight problems account for most of the stalled or fragile SaaS builds we see. Each one has a proven, production-grade fix we run as standard.

  • Single-tenant architectureOne customer per deployment. Scaling becomes operational pain. We design multi-tenant models with clear isolation from day one.
  • Billing bolted on lateSubscriptions and plans added after launch break the product. We wire billing, plans and entitlements into the core early.
  • Weak tenancy boundariesData leaks and permission bugs under multi-customer load. We enforce isolation at the data and API layer with tests.
  • No path from trial to paidFree users never convert. We design onboarding, limits, upgrade paths and dunning that support real revenue.
  • Shopify app without depthThin shells that ignore Admin API, billing API and app store requirements. We build apps that pass review and scale with merchants.
  • Ops and support chaosNo admin tools or audit trails. We ship internal ops surfaces so your team can support customers without engineering every ticket.
  • Security and compliance gapsMissing audit logs, weak auth or unclear data handling. We design for least privilege, encryption and clear data ownership.
  • No ownership of the productCode and infra locked with the vendor. We deliver repos, credentials, schemas and runbooks so you fully own the SaaS.
SaaS capabilities

Sixteen ways we design and ship multi-tenant SaaS products

From tenancy and billing to Shopify apps, onboarding, ops consoles and observability. Products built to sell, scale and retain.

Multi-tenant architecture

Tenant isolation at data and API layer, shared infrastructure and clear boundaries so one customer never sees another’s data.

Billing & subscriptions

Plans, trials, upgrades, proration and dunning via Stripe, Shopify Billing or similar — wired into entitlements from day one.

Auth, roles & permissions

SSO, invite flows, org roles and fine-grained permissions so teams can work safely inside each tenant.

Shopify App Store products

Public and custom apps with Admin API, Billing API, webhooks and review-ready compliance for the App Store.

Onboarding & activation

Guided setup, empty states and first-value moments so new tenants reach aha before they churn.

Usage metering & limits

Feature and usage limits tied to plans so you can offer free tiers without unlimited cost or abuse.

Admin & ops console

Internal tools for support, billing overrides, audit logs and tenant health so your team can operate the product.

APIs & webhooks for partners

Public or partner APIs with clear contracts so integrators and power users can extend the product.

Observability & SLOs

Metrics, logs, traces and tenant-aware alerting so you know health per customer and overall platform.

Data model & migrations

Schema design for multi-tenancy, safe migrations and export paths so data stays yours and portable.

Security & compliance basics

Encryption, audit logs, least-privilege access and clear data handling practices ready for customer diligence.

Marketplace & multi-seller

Seller onboarding, payouts and catalogue models when the product is a marketplace or multi-vendor platform.

Legacy to multi-tenant

Migrate single-tenant or fragile apps onto a proper multi-tenant architecture without losing customers.

Product analytics

Activation, retention and revenue events so you know which features drive paid growth.

International & multi-currency

Localisation, tax and multi-currency billing when your SaaS sells across regions from day one.

Post-launch product retainers

Ongoing roadmap, incident ownership and feature sprints so the product keeps improving after launch.

Product retainers

Ongoing roadmap, incident ownership and feature sprints after launch.

How a SaaS development engagement runs

Every engagement follows the same four stages. You always know what is happening next and how success is measured at each milestone.

Stage 1

Product & architecture discovery

We clarify ICP, pricing model, tenancy needs and success metrics, then lock the architecture: isolation model, billing, auth and first-release scope.

Stage 2

Design system & core flows

Tenant onboarding, plan selection, core product flows and admin surfaces are designed so activation and support are possible from day one.

Stage 3

Build, harden & launch

Sprint-based development with tenancy tests, billing integration, observability and a launch path that can take real paying customers.

Stage 4

Measure, iterate & scale

Activation and retention metrics in place. We refine based on real usage and offer retainers for roadmap, incidents and growth features.

Tech stack

What we use for SaaS development

Modern TypeScript and Python services, multi-tenant data models, Stripe or Shopify Billing, and observability from the first commit — never a single-tenant shell that cannot scale.

  • You own the productFull repository access, credentials, schemas and runbooks. We stay because the work is good, not because exit is hard.
SaaS Development FAQ

Questions we hear before every SaaS engagement

Honest answers, including the ones most agencies dodge.

How long does a typical SaaS build take?

Focused multi-tenant MVPs often run 12–20 weeks. Full products with billing, ops and App Store readiness usually take 16–28 weeks. Timeline is fixed in the SOW before work starts.

Do you only build Shopify apps?

No. We build general multi-tenant SaaS and Shopify App Store products. When commerce is central we lean on Shopify APIs and Billing; otherwise we use Stripe and standard SaaS patterns.

Can you fix an existing single-tenant product?

Yes. We assess tenancy, billing and security gaps and can migrate to a multi-tenant architecture without losing existing customers, often in phases.

What does a typical engagement cost?

Projects: $25K–$150K. Monthly retainers: $5K–$18K/mo. Dedicated team: $12K–$32K/mo. Every quote is fixed-fee and locked in the SOW.

How do you handle billing and plans?

We integrate Stripe or Shopify Billing early, model plans and entitlements in the core data layer and wire upgrade, proration and dunning so revenue is not an afterthought.

Do you support the product after launch?

Yes. Retainers cover roadmap, incidents, feature sprints and growth work. Most clients keep a product retainer after the initial launch.
