ISV & AppExchange Development

Salesforce AppExchange App Development Services

Turn your Salesforce app idea into a listed, commercially viable AppExchange product. RASPSYS LLP handles everything from managed package architecture and ISV development through security review preparation and go-to-market listing strategy.

Full-Lifecycle AppExchange Development

From initial concept and package architecture through security review and live listing, RASPSYS LLP provides the technical expertise and process knowledge to get your app to market.

Managed Package Development

Design and build Salesforce managed packages — the standard for distributing licensed AppExchange applications — with a namespace, upgrade-safe architecture, and subscriber org management capabilities built in from the start.

  • Namespace registration and Dev Hub setup
  • Upgrade-safe Apex, LWC, and metadata design
  • Version lifecycle management
  • Subscriber licence enforcement patterns

Unlocked Package Development

Build modular, version-controlled unlocked packages for internal distribution or enterprise deployments where you need faster iteration cycles without the overhead of a full managed package.

  • Package dependency mapping and architecture
  • Scratch org development with SFDX
  • CI/CD pipeline for automated package builds
  • Installation and upgrade documentation

Security Review Preparation

The Salesforce AppExchange Security Review is a stringent process. RASPSYS LLP prepares your package with a security-first code review, PMD static analysis, and remediation of all known issues before submission — maximising first-pass approval rates.

  • Apex security patterns (CRUD, FLS, sharing rules)
  • PMD and Checkmarx static analysis remediation
  • XSS, SOQL injection, and CSRF prevention
  • Security review submission support and Q&A

AppExchange Listing & Partner Portal

Navigate the Salesforce Partner Community and AppExchange Partner Portal to create a compelling listing that converts visitors to installers — with optimised descriptions, screenshots, and trial/demo org setup.

  • Partner Community registration and setup
  • Listing copy, screenshots, and demo video guidance
  • Trial and Trailhead Playground configuration
  • Review strategy and customer success plan

Custom App Architecture & Development

Build the functional core of your AppExchange application using modern Salesforce development practices — Lightning Web Components, custom objects, Apex services, and Platform Events — designed for multi-tenant performance and reliability.

  • Lightning Web Component UI development
  • Apex service layer and trigger framework
  • Custom Settings and Custom Metadata for configurability
  • Governor limit compliance design

Post-Launch Maintenance & Upgrades

Keep your AppExchange app current with Salesforce's three annual releases, handle subscriber support escalations, and continuously improve your product based on user feedback and review data.

  • Salesforce seasonal release compatibility testing
  • Managed package version upgrades
  • Bug fix and enhancement development
  • Subscriber org diagnostics and support

AppExchange Expertise Without the ISV Learning Curve

Building for the AppExchange is fundamentally different from building for a single org. The multi-tenancy requirements, security review standards, and package lifecycle management add significant complexity. RASPSYS LLP has navigated this complexity before, so you do not have to start from scratch.

  • Deep experience with both managed and unlocked packages
  • Strong track record through Salesforce security review
  • Modern SFDX-first development practices
  • Understanding of ISV licensing models and commercial structures
  • Long-term partnership approach for post-launch product evolution

Frequently Asked Questions

If you intend to sell or distribute your app commercially on AppExchange to multiple subscriber orgs, a managed package is required — it provides the namespace, licence enforcement, and intellectual property protection that the AppExchange model depends on.

Unlocked packages are better suited for internal enterprise distribution, where you want modular, version-controlled components deployed across your own orgs without the constraints of a managed package. RASPSYS LLP will advise on the right choice based on your commercial model and distribution intent.

Salesforce's Security Review typically takes 4–6 weeks from submission to outcome, though timelines can vary based on the review queue. A first submission that fails requires remediation and resubmission, which can add several more weeks.

RASPSYS LLP significantly improves first-pass approval rates by conducting a thorough internal security review before submission — running static analysis, manual code review, and testing against all documented security requirements. This upfront investment dramatically reduces the total time to listing.

Yes. RASPSYS LLP has worked within the Salesforce Partner Community and is familiar with the Salesforce ISV Programme requirements, including the Partner Business Org (PBO) setup, AppExchange Partner Agreement, and the Technology Partner licence model.

We guide clients through the registration process, help set up the Dev Hub and packaging org correctly, and provide ongoing support as their relationship with Salesforce as a partner evolves.

Absolutely. We regularly work with ISVs who have received a failed security review and need expert remediation. Our process starts with a thorough analysis of the failure report, followed by a prioritised remediation plan and hands-on code fixes.

Common issues we address include missing CRUD/FLS enforcement, insecure SOQL patterns, LWC XSS vulnerabilities, and hardcoded credentials. Once remediated, we conduct a final pre-submission review before you resubmit to Salesforce.
