Custom SaaS

Custom SaaS app built around your product model

Delivery path 01

Hire Flatlogic

Best when you need senior help with SaaS scope, billing, integrations, architecture, and launch.

Delivery path 02

Use the builder

Best when your team wants a generated SaaS codebase it can own, deploy, and keep extending.

Open builder

Build the SaaS around tenants, subscriptions, onboarding, permissions, analytics, and the customer workflows that actually make the product valuable.

Multi-tenant SaaS foundation with source-code ownership Billing, roles, onboarding, admin dashboards, and APIs Use Flatlogic as your delivery team or your build platform

Builder preview

Start from a SaaS prompt, then keep shaping the product on a real codebase and dedicated deployment path.

Track Record

Move from a generated foundation to an owned product with concrete delivery evidence. Review the Worldsphere platform case study or explore all Flatlogic case studies.

Core Capabilities

What changes when an internal tool becomes SaaS?

Company-specific assumptions become account rules: who can see each record, how customers configure the workflow, and how subscriptions affect access.

Tenant and workspace icon

Tenants, workspaces, and roles

Set up organizations, users, invitations, roles, permissions, and account-level settings before the product becomes hard to control.

SaaS billing icon

Billing and product lifecycle

Add plan structure, subscription states, trials, onboarding, usage limits, emails, and admin controls around the customer lifecycle.

SaaS launch icon

Launch-ready operations

Ship dashboards, imports, API endpoints, webhooks, audit logs, and deployment setup so the first release can run with real users.

Why Custom

Choose custom when the SaaS model is part of the product advantage

Custom SaaS is the right shape when onboarding, billing, tenants, permissions, and product analytics are part of the product itself. If the core workflow is sales or account management, compare Custom CRM. If it needs operations, inventory, or finance modules, compare Custom ERP.

Start with a specification of your domain workflow, then scope custom software delivery or build the first version yourself.

If the first release needs a deliberately narrow launch boundary, compare MVP in a Week. If the product also needs a deep operator control surface, review Admin Panel before locking the architecture.

Built for product fit, launch speed, and ownership

Key Workflows

The SaaS has to support the customer lifecycle end to end

The product should make setup, paid access, daily usage, support, and admin operations visible instead of scattering them across disconnected tools.

Custom SaaS onboarding and template builder preview

Customer onboarding

A SaaS product needs a clean path from signup to first value, with the right setup steps for each account.

  • Organization creation and user invitations
  • Trial, plan, or account-state handling
  • Guided setup screens and email flows
Custom SaaS subscription plan and access control preview

Subscription and access control

Billing and permissions should shape product access without forcing manual support work for every account change.

  • Plan features, seats, limits, and upgrades
  • Role-based views and admin-only actions
  • Payment, invoice, and account status flows
Custom SaaS operator analytics dashboard preview

Operator dashboard

Founders and operators need visibility into accounts, usage, activation, errors, and the workflows that need attention.

  • Account and usage reporting
  • Support, admin, and moderation screens
  • APIs, exports, and integration readiness

Plan the Product

Custom SaaS pricing, timeline, and delivered proof

Choose the build path with a clear view of how pricing works, how delivery progresses, and what a real Flatlogic platform engagement produced.

Custom SaaS pricing icon

Start self-serve or scope custom delivery

Start on the Free builder plan and compare the current paid options on the Flatlogic pricing page. Assisted SaaS delivery is estimated after the account model, first-release workflow, integrations, and launch requirements are clear.

Custom SaaS delivery timeline icon

Working software in visible increments

The builder can generate the first full-stack foundation in one working session. Assisted delivery starts by locking the account model and release boundary, then moves through working weekly increments; billing, migrations, integrations, and security requirements determine the total timeline.

Domain expertise to SaaS: Watt Footprint

Watt Footprint turned energy expertise into an owned SaaS product. Flatlogic built company and site workflows, bill capture and review, dashboards, and ongoing releases.

Build Path

Move from SaaS idea to working product in clear steps

Start with the account model, generate the first version, add the product-specific workflows, then launch and keep improving the same codebase.

  • Define the SaaS account model

    Lock tenants, users, roles, plans, onboarding, and the core workflow so the first release has a clear product boundary.

  • Generate the first working product

    Use Flatlogic to create the app foundation with database, frontend, backend, authentication, and deployment wired together.

  • Add the product-specific workflows

    Build the parts that make the SaaS valuable: dashboards, data entry, automation, imports, payments, notifications, or customer portals.

  • Launch, measure, and keep ownership

    Deploy the product, watch how customers use it, and keep improving the same codebase without rebuilding on another platform.

Questions

Questions teams ask before they build custom SaaS software

Yes. You can use Flatlogic as a self-serve builder, or hire our team to scope, build, launch, and maintain the SaaS product with you.

The first work separates each company's records, users, billing, and configuration. Scope includes invitations, roles, any customer identity provider, and backup and recovery expectations. Acceptance tests cover the complete import-to-report workflow, revoked access, and attempts to read another company's data through a direct link or API.

Custom-development ownership and handover are defined in the project agreement. Generated application output has separate license terms: commercial use requires an active paid plan and source-access activation for that application. Repository access does not change those terms. Read the application license terms. See delivery and handover.

Yes, when the differences can be configuration. For example, customers can use different approval limits within the same workflow. A different calculation or integration may need custom development. We separate those requirements during scoping.

One complete task connects login, customer records, billing state, background work, and a checked result. A new account tests successful and failed imports, missing permissions, and help when stuck. Release checks also cover integration failures, monitoring, backups, and recovery. Generated screens do not establish that these paths work.

You can start on the Free builder plan and move to a paid plan as you need more credits, private apps, and collaborators. Manual stable deployment is currently disabled. Assisted development is estimated after the account model, core workflow, billing, integrations, migration, and launch requirements are scoped.

The builder can generate the first full-stack foundation in one working session. Assisted delivery starts by defining the account model and release boundary, then ships working increments weekly. Billing, data migration, integrations, security, and the size of the core workflow determine the full schedule.

Customer accounts within one SaaS product differ from separate client applications. The generator terms grant one end-user application per source-access activation; additional applications require separate activation. Template terms and any separately negotiated development agreement also apply. The deployment and customer model needs to be explicit when confirming the license scope. Read the current terms.
