Salesforce Development for Apex, Flow and LWC

Custom Salesforce development that your team can read, test and maintain after we leave: Apex, Flow, Lightning Web Components and the release process around them.

Most Salesforce orgs reach a point where configuration alone stops being enough. A sales process needs logic that a validation rule cannot express, an integration needs a callout with proper retry handling, or a user interface needs to show data from three objects on one screen. That is where custom development starts, and where many orgs quietly accumulate risk: triggers that fail on bulk loads, flows that nobody can explain, and code with tests written only to reach the coverage threshold.

Who this service is for

We work with platform owners, Salesforce admins who have outgrown declarative tools, and technical leads who need extra engineering capacity with Salesforce depth. Typical situations include:

  • A backlog of requirements that need Apex or Lightning Web Components, with no in-house developer to build them.
  • An existing codebase that hits governor limits, fails during data loads or breaks after releases.
  • Automation spread across Process Builder, workflow rules, flows and triggers on the same object, with unclear order of execution.
  • Deployments done by hand through change sets, with no version control or repeatable release process.

What we build and fix

Choosing between Flow and Apex

We do not default to code. Flow is often the better choice when admins will own the logic and the volume and complexity are moderate. Apex earns its place when you need complex data processing, fine control over transactions and error handling, heavy bulk volumes, or logic that is hard to express and test visually. For each requirement we write down which tool we chose and why, so the decision can be revisited later. Our Flow vs Apex guide sets out the trade-offs in more detail.

Engineering standards we apply

  • One automation strategy per object. Before adding logic, we map what already runs on that object so new work does not collide with existing triggers or flows.
  • Bulk safety by default. Every trigger and invocable method is written and tested against collections of records, not single records.
  • Tests that assert behaviour. Salesforce requires a minimum level of Apex test coverage to deploy to production, but coverage is a floor, not a measure of quality. Our tests create their own data, check outcomes and cover failure paths.
  • No hard-coded IDs or credentials. Configuration lives in custom metadata, custom settings or Named Credentials.
  • Readable code. Consistent naming, small methods and comments that explain why.

How a development engagement runs

  1. 01

    Discovery and review

    We review the requirement, the current org metadata and existing automation on the affected objects, then confirm scope and acceptance criteria with you.

  2. 02

    Solution design

    A short design note covers the data model impact, the Flow or Apex choice, error handling, security and the test approach. You approve it before build starts.

  3. 03

    Build in a sandbox

    Development happens in a developer or partial sandbox, with work committed to version control so every change is traceable.

  4. 04

    Code review and testing

    Peer review against our standards, Apex and Jest tests, and functional testing against the agreed acceptance criteria.

  5. 05

    User acceptance testing

    Your users test in a full or partial copy sandbox with realistic data. We fix defects and record sign-off.

  6. 06

    Deployment and handover

    We deploy through the agreed pipeline, run post-deployment checks and walk your team through the code and documentation.

What you receive

  • Source code in your version control repository, not ours.
  • Automated tests with meaningful assertions.
  • A design note for each significant feature, including the reasoning behind tool choices.
  • Deployment steps and any manual post-deployment actions written down.
  • A handover session recorded or documented for your admins and developers.

What we need from you

Development goes faster and safer when we have sandbox access with appropriate permissions, a named product owner who can answer questions and accept work, and access to the people who understand the business process. If the requirement depends on a third-party system, we will also need API documentation and a test environment for that system. If requirements are still loose, see writing requirements developers can build.

Questions we hear

Can you work alongside our existing developers?
Yes. We can follow your coding standards and branching model, take tickets from your backlog and take part in your code reviews, or propose standards if you do not have them yet.
Do you only build new features, or also fix existing code?
Both. A good share of development work is remediation: fixing bulk failures, removing SOQL and DML from loops, and replacing tests that pass without checking anything.
Will we be locked into your way of working?
No. Code lives in your repository and follows documented patterns, so your team or another provider can maintain it.
How do you estimate development work?
We estimate after reviewing the requirement and the affected parts of the org, and we call out assumptions and unknowns that could change the estimate.
