Custom Salesforce Development for UK Businesses
When Salesforce's standard configuration and Flow automation reach their limits, we build custom Apex, Lightning Web Components, and bespoke applications — clean, documented, and built to scale.
When Salesforce's standard configuration and Flow automation reach their limits, we build custom Apex, Lightning Web Components, and bespoke applications — clean, documented, and built to scale.
Salesforce's built-in tools — Flows, Process Builder, validation rules, formula fields — can handle the vast majority of business automation requirements without writing a single line of code. Custom development should be a last resort, not a first instinct.
But there are genuine scenarios where standard configuration can't deliver what your business needs. Complex data transformations, bulk processing across millions of records, external API callouts with custom retry logic, or a user interface that simply doesn't exist in Salesforce's standard component library. That's where custom development becomes the right answer.
You probably need custom Salesforce development if:
From a single Apex trigger to a full custom application on the Salesforce Platform, we scope and deliver exactly what your business requires.
Bulk-safe, well-tested Apex code for your most complex business logic. We write to Salesforce's recommended patterns — one trigger per object, handler classes, full test coverage — so your code survives future platform releases and can be maintained by another developer without reverse-engineering.
Custom UI components that embed directly into Salesforce record pages, app pages, or Experience Cloud portals. We build data visualisations, multi-step input forms, interactive dashboards, and any other interface your team needs to work more efficiently inside Salesforce.
Salesforce Flow is powerful and often underestimated. We build complex, multi-object flows with subflows, loops, and custom Apex actions for the pieces where a purely declarative approach genuinely works better — keeping your system maintainable for administrators who aren't developers.
Need a completely bespoke application built on the Salesforce Platform? We design the data model, build the UI and business logic, and deploy a fully working application that leverages your CRM data while providing unique functionality your business can't get from an off-the-shelf product.
Build Apex classes that call external REST or SOAP APIs — with proper error handling, retry logic, and Named Credentials for secure authentication. Whether it's a payment gateway, a logistics platform, or a bespoke internal system, we integrate it cleanly into Salesforce's asynchronous processing model.
Inherited broken or poorly written Apex code? We review your existing codebase, identify governor limit risks, missing test coverage, security vulnerabilities, and non-bulkified triggers — then fix what needs fixing and document what we find so you understand your system.
Custom code is a long-term commitment. We write it in a way that your team can own, maintain, and extend — with or without us.
Before writing a line of Apex, we explore whether Salesforce Flow, Process Builder, validation rules, or formula fields can meet the requirement. We only recommend custom code when it's genuinely the better solution.
All Apex follows Salesforce Apex best practices: one trigger per object, handler classes, bulkification, Named Credentials for API auth, and no hard-coded IDs. Code that follows the platform's conventions survives releases and is maintainable by any certified developer.
Salesforce requires 75% test coverage to deploy. We target 90%+ and write tests that validate real business logic and edge cases — not just lines executed. Test classes are delivered with every Apex project as first-class code, not an afterthought.
Every project includes inline code documentation and a written summary of what was built, why, and how to maintain it. You can hand this to an internal admin, a future developer, or a new agency — without losing the knowledge.
All code is built and tested in a Salesforce Sandbox first. You get a User Acceptance Testing period to review the solution against real business scenarios before we deploy to production. Nothing goes live without your sign-off.
Apex test classes covering positive paths, negative paths, and bulk scenarios. Delivered as part of the project — not invoiced separately. Includes documentation of what each test validates.
We can deploy using Salesforce Change Sets or, for teams with more mature DevOps practices, via SFDX CLI and a Git-based pipeline. We match the deployment method to your team's capability and tooling.
A plain-English summary of what was built, the business logic it implements, any configuration dependencies, and how to modify or extend it in future. Delivered as a document your admin can actually read and use.
We monitor your production org for issues in the first two weeks after deployment. If anything unexpected surfaces, we fix it without additional charge as part of the project warranty.
After the project closes, we offer monthly support contracts covering bug fixes, enhancements, and monitoring. Month-to-month, no minimum term — useful if your requirements are likely to evolve after launch.
Custom development isn't for every Salesforce user — but it's the right answer for some specific situations.
You've outgrown the standard Salesforce setup you implemented 18 months ago. Your data volumes, team size, and process complexity have all increased — and Flows that worked fine at 1,000 records now hit limits at 100,000. We build the custom layer your growth requires.
Discuss Your RequirementsA previous developer or agency left you with Apex triggers that fire on every save and slow the system to a crawl, or test classes that are just coverage padding with no real assertions. We diagnose and fix — or rewrite where necessary.
Get a Code ReviewYou're using Salesforce as a platform to build a bespoke application — not just a CRM. Whether it's a custom field service app, a project management tool, or a client-facing portal, we architect and build it properly from day one.
Explore Custom App DevelopmentFlow handles the majority of automation requirements — and it should always be evaluated first. Apex is needed when you have complex branching logic that becomes unmaintainable in Flow, need to process large volumes in bulk, make callouts to external APIs, or require precise transaction control. We always explore Flow before recommending Apex.
LWCs are the modern framework for building custom UI inside Salesforce. You need them when you want a custom view, chart, or interactive component that doesn't exist in standard Salesforce — such as a bespoke order panel on an Account page, a custom data visualisation, or a multi-step form with complex validation.
Cost depends on scope. A single Apex trigger with test coverage might cost £800–£2,000. A custom LWC component typically ranges from £1,500–£5,000. A full custom application varies widely. We provide fixed-price quotes after a free scoping call — you know the full cost before we start.
Salesforce maintains backward compatibility for supported API versions. Code written to Salesforce's documented best practices survives releases. We write to the current API version, test against pre-release environments where possible, and our support contracts include monitoring for post-release issues.
Yes — always. Salesforce requires 75% test coverage to deploy to production, but we target 90%+ with tests that cover real business scenarios, not just coverage padding. Test classes are part of every Apex project, delivered and documented so your team can extend them.
Yes. We regularly review and remediate code from previous developers or agencies — fixing non-bulkified triggers, missing test coverage, hard-coded IDs, and unhandled exceptions. We give you an honest assessment of what needs fixing and what's safe to leave in place.
