# XpertApps

> XpertApps (legal name QuoDroid) is a specialist ServiceNow application development and certification firm. We design, build, and certify custom ServiceNow apps for the ServiceNow Store, build AI agents and integrations, and publish XpertApps Engineer — a Chrome/Edge browser extension that helps ServiceNow developers understand and safely change their instances. Founded by Saurav Sarkar, a former member of the ServiceNow certification team. Track record: 25+ certified apps, every one certified and listed — typically in under fifteen days each.

## Services

- [ServiceNow Services](https://xpertappdev.com/services/): Custom app development, AI agent building, ServiceNow Store certification, integration, and ongoing support — concept to Store listing.
- [Our Process](https://xpertappdev.com/services/process.html): A repeatable, certification-first delivery process in five structured phases, built from 25+ successful ServiceNow app engagements.
- [ServiceNow App Certification Guide](https://xpertappdev.com/services/certification-guide.html): Practical guide to ServiceNow Store certification — partner-program enrolment and its fee, vendor instances and PDI conversion, what App Review and Listing Review each check, the real timeline, and the five pitfalls that cost vendors review cycles. Written by a former ServiceNow certification team member.

## Guides & decodes

- [ServiceNow Guides & Decodes](https://xpertappdev.com/blog/): Working notes on the ServiceNow surfaces the official documentation does not explain, written for developers building and certifying Store apps.
- [ServiceNow Read-Only Options in the Australia Release](https://xpertappdev.com/blog/servicenow-read-only-options-australia.html): The Australia release replaces the dictionary read-only checkbox with a four-option choice field — Display Read Only, Client Script Modifiable, Strict Read Only, Instance Configured. Only Strict Read Only blocks both client scripts and server-side APIs. Fields created before Australia default to Instance Configured, whose behaviour resolves from a property on the customer's instance, so one certified app can enforce data protection differently per customer. Certification review raises this when forward-migrating a Zurich-certified app, because the choice values do not exist on the older release. Covers the trade-off between shipping two app versions and one version with a version-detecting fix script.

## Newsletter

- [The Delivery Edge](https://xpertappdev.com/newsletter/): A weekly newsletter by founder Saurav Sarkar for ServiceNow implementation and build partners, on protecting delivery margin in the AI-build era. Core argument: AI can now write ServiceNow change, but it cannot prove the change is correct — on this client's instance, against their process, with evidence. That proof is the partner's margin, and nobody measures it. Issues are published at xpertappdev.com/newsletter/ first; republished copies elsewhere carry a canonical link back here.
