M40Tech is your end-to-end partner for Salesforce AppExchange App Development Services — from ideation and architecture to security review, marketplace listing, and ongoing growth. We build apps that pass review the first time and generate recurring revenue.































From concept validation to post-launch growth strategy, M40Tech delivers the full spectrum of AppExchange App Development services that turn your idea into a revenue-generating Salesforce product.
We validate your app concept against market demand, define your target audience, analyse competitor listings, and build a go-to-market roadmap that positions your app for maximum visibility and downloads on the Salesforce AppExchange marketplace.
Our architects design scalable, multi-tenant app architectures using managed packages, Lightning Web Components, and namespace-isolated code — ensuring your app works seamlessly across thousands of Salesforce orgs with different configurations.
We build robust backend logic in Apex and polished frontend interfaces in Lightning Web Components — governor-limit-safe, bulkified, and built for enterprise scale.
We prepare your app for Salesforce's rigorous security review — addressing vulnerabilities, CRUD/FLS enforcement, CSP compliance, and automated scanning before submission.
We optimise your listing with compelling copy, screenshots, demo videos, and pricing strategy — then manage the full submission and approval workflow.
Comprehensive testing across Salesforce editions, org configurations, Lightning and Classic modes, and mobile — ensuring zero-defect installs for every customer.
We build secure REST/SOAP integrations, webhook handlers, and external service connectors that extend your app's functionality beyond Salesforce boundaries.
Ongoing managed services including version upgrades, feature enhancements, user feedback loops, analytics dashboards, and scaling for enterprise adoption.
