Why eCorpIT

Why hire SaaS developers through eCorpIT.

SaaS mobile is its own discipline. The companion app to a B2B SaaS web product carries responsibilities most mobile builds do not: multi-tenant data isolation, SSO via SAML or OIDC, RBAC with the customer’s identity provider as source of truth, SCIM provisioning for enterprise customers, and SOC 2 audit-trail logging that survives the customer’s audit.

Manu Shukla reviews every SaaS engagement at architecture and milestone stages. The engineer whose CV you interviewed is the engineer who ships.

US seniors $90–$160/hr
UK seniors £50–£95/hr
eCorpIT $44–$48/hr (senior)

A 60–70% vs US specialists saving at the same seniority, on a dedicated pod with an MSA and DPA signed before code is written. Industry rate benchmarks.

  • Multi-tenant by default

    Tenant ID is a first-class concept in every schema, API route, cache key and log entry. Cross-tenant leakage is the failure mode SOC 2 auditors look for — multi-tenant correctness is the first thing we review on every PR.

  • SSO via SAML 2.0 & OIDC

    Okta, Microsoft Entra ID, Google Workspace, OneLogin, Auth0, JumpCloud. Both SP-initiated and IdP-initiated flows in production builds — not a single library call.

  • SCIM 2.0 provisioning

    User lifecycle automated from your enterprise customers’ HRIS — create, update, deactivate, delete, plus group sync. Shipped for B2B SaaS selling into Fortune 500 procurement.

  • RBAC & ABAC

    Role- and attribute-based access control with the customer’s identity provider as source of truth. Fine-grained permission models that survive an enterprise access-review.

  • SOC 2 Type II-aware design

    Trust Service Criteria mapping, audit-log tables for every read/write of customer data, infrastructure controls that map cleanly to your auditor’s expectations. We make the audit straightforward — the SaaS firm is the one certified, not the vendor.

  • Feature flags & tiered rollout

    LaunchDarkly, Statsig or your own server-side service. Tenant-aware and tier-aware rollouts built into the architecture by default.

Transparent pricing

SaaS rate card (USD, hourly).

Same rate card as the umbrella hire page. SaaS work is typically staffed at the Senior or Lead tier for enterprise-tier customers; Junior engineers work productively on the SMB/self-serve tier under senior pairing. All-in, weekly invoicing, net 14.

Tier Experience Flutter / RNiOSAndroid
Junior 1–2 years $22/hr$24/hr$22/hr
Mid-level 3–5 years $32/hr$35/hr$32/hr
Senior 6+ years $44/hr$48/hr$44/hr
Lead / Architect 8+ years $58/hr$62/hr$58/hr

For a typical US-bought SaaS mobile companion at 160 hours/month with one Senior plus shared backend support, that is about $42K eCorpIT versus $108K at the US senior midpoint. Same enterprise-customer comfort, same shipped app.

How you work with us

Four engagement models.

You pick the one that fits how you actually want to work. We do not push everyone into the same shape.

Hourly

True Time & Materials

Weekly invoicing, minimum 40 hours per month, weekly demos. You pay only for the hours we log against your project board. Best for SaaS maintenance, SSO integration updates, or feature parity with web.

Monthly

Dedicated developer · 10% off

160 hours per month, dedicated. 10% discount on the hourly rate. The engineer attends your standups, sits in your Slack, follows your sprint cadence. Pause with 30 days’ written notice. Best for active builds.

Quarterly

Pod · 480 hours · 15% off

3-month commit, 15% discount on hourly. Includes a shared designer (40 hours) and a shared QA engineer (40 hours) at no additional cost. The pod model — a real team behind one engineer.

Project

Fixed scope · fixed price · fixed timeline

$15K (SaaS-aware) MVP starting (a small premium over the $8K cross-platform start because multi-tenant and SSO add real complexity). We own scope, milestones and acceptance criteria. Weekly demos, weekly invoicing against milestones. Best when the spec is well-defined and you want predictability.

All four models include the NDA signed before any technical conversation, an MSA with India and EU/UK-aligned clauses, a DPA aligned with GDPR and India’s DPDP Act, weekly invoicing, and a single named delivery lead for the whole engagement. SOC 2-aware delivery from Sprint 1.

Answers, up front

How much does it cost to hire SaaS app developers?

eCorpIT senior SaaS engineers bill $22–$58/hour by seniority — about 60–70% below US cost — for multi-tenant architecture, SSO/SAML, RBAC and billing integrations. You hire a senior pod (engineering plus optional design and QA) on flexible hourly, monthly or quarterly terms.

What makes a good SaaS developer?

SaaS demands multi-tenant data isolation, SSO/SAML and RBAC, usage metering and billing (Stripe), and a SOC 2-aware security posture — not just app skills. eCorpIT matches senior engineers who have shipped production multi-tenant platforms, with the compliance scaffolding built in from day one.

FAQ

Questions, answered.

What US and UK teams ask before hiring SaaS developers with us.

Do you build SOC 2-compliant SaaS apps?
We build SOC 2-aware apps with the multi-tenant isolation, audit-trail and access-control patterns that map cleanly to Trust Service Criteria. Final SOC 2 Type II attestation is the SaaS firm’s audit, not the vendor’s — we make the audit straightforward.
Will you sign a DPA aligned with SOC 2 sub-processor expectations?
Yes. Our default DPA includes sub-processor disclosures, audit-cooperation clauses and incident-notification timelines that map to SOC 2 Common Criteria.
Can you integrate with Okta, Microsoft Entra ID, Auth0, OneLogin, JumpCloud?
Yes — SAML 2.0 and OIDC for each, both SP-initiated and IdP-initiated. Production experience for US and UK B2B SaaS selling into Fortune 500 and FTSE 250.
Can you ship SCIM 2.0 user-lifecycle provisioning?
Yes — create, update, deactivate, delete, plus group membership sync. Required by enterprise customers with HRIS-driven access management.
What are your SaaS rates vs a US SaaS-specialist agency?
eCorpIT senior rate is $44–$48/hour. US SaaS-specialist agencies bill $90–$160/hour at the same seniority. Arbitrage is 60–70% on like-for-like work.
Do you handle multi-tenant data isolation review?
Yes — multi-tenant correctness is the first thing we review on every PR. Tenant ID as a first-class concept in schemas, APIs, cache keys and logs.
Can a SaaS mobile companion keep pace with the web release cadence?
Yes — the Monthly model is designed for it: 160 hours/month of dedicated senior engineering aligned to your web sprint cadence.
Who actually writes the code?
The engineer whose CV you interviewed. No bait-and-switch, no junior backfill on enterprise-tier workloads.
