Salesforce Migration & Modernization

Stop paying CRM prices for an operational system Salesforce was never designed to run.

We replace Salesforce-based operational platforms with purpose-built systems that make your business logic visible, testable, and fast to change. Every record preserved. Every relationship intact.

The Problem

You’re not using Salesforce as a CRM.

You’re running your core operations on it — compliance tracking, vendor management, multi-party workflows, document processing — and the cracks are showing.

Feature velocity has collapsed.

Your SF admin says a straightforward change will take three months because it touches Flows, Apex, formula fields, and batch jobs that nobody fully understands. Every enhancement is an archaeology project.

Your business logic is invisible.

Compliance rules, approval routing, and status calculations are scattered across formula fields, Flows, Apex triggers, and scheduled batch jobs with hidden dependencies and race conditions. When something computes wrong, nobody can explain why.

Licensing costs scale against you.

Per-seat pricing for an operational tool means every new hire, every vendor portal user, every external partner is a cost event. You’re paying CRM rates for people who never touch a pipeline.

External users get a second-class experience.

Experience Cloud is expensive, limited, and awkward for vendors and partners who need to submit documents, check compliance status, or complete onboarding workflows. You know it. They know it.

Why Heavy Chain

We know what’s hiding in your Salesforce org.

On our last engagement, we replaced a Salesforce operational platform for a B2B company managing industrial vendor compliance. The org had become the most complex system in the building — and nobody could explain how it worked.

The complexity we untangled

A 4,096-line Apex class. 25 obsolete Flows still deployed. Compliance logic scattered across six components with race conditions between them. A junction table with 2 records while 9,518 relationships hid in a lookup field on Account.

What we delivered

A 12-bounded-context architecture on PostgreSQL, FastAPI, React, and Temporal. The compliance engine became a single deterministic evaluator. 4,000+ backend tests at 98% coverage. 37 ADRs so the next team never has to reverse-engineer what we reverse-engineered.

Our Process

Three phases. Clear milestones. No ambiguity.

Phase 01

Operational Audit

2–3 weeks, fixed price

We get read-only access to your Salesforce org and produce a complete component inventory, data model map, and business logic dependency graph for your critical processes. This usually reveals things nobody knew: dead Flows still deployed (we found 25 of 37 were obsolete), formula fields masquerading as business logic, batch jobs with undocumented side effects.

You also get a cost comparison — current SF total cost of ownership versus a purpose-built replacement. The audit is valuable even if you never migrate.

Phase 02

Platform Build + Migration

3–6 months, fixed scope

We design the domain model, build the replacement platform, and construct a validated ETL pipeline — all in defined phases with concrete milestones. The staging-first architecture means Salesforce keeps running during development. The cutover is a discrete event: dry-run, validate, switch.

You’re not paying for two systems for 18 months. Each migration wave is independently testable, idempotent, and reversible. Post-migration validation includes row counts, foreign key integrity checks, and business rule assertions compared against Salesforce’s own computed values.

Phase 03

Optimization + Retainer

Ongoing

The whole point of leaving Salesforce is that changes should be fast. A monthly retainer means you can request features without procurement cycles. We maintain deep context on the codebase, so changes are faster and safer than onboarding a new team.

After 12 months, you can bring development in-house — the ADRs, test suite, and documentation are designed for handoff. We’ll say that upfront because it’s true.

Let’s talk.

If you’re running operations on Salesforce and it’s costing you speed, money, or sanity, let’s talk. The 30-minute assessment call is straightforward: you describe what Salesforce is doing for your business, we tell you honestly whether migration makes sense or whether you should just clean up your org.

No deck. No discovery phase disguised as a sales cycle. Just a direct conversation with the engineer who’ll do the work.
