Salesforce Custom Development vs Lightweight Custom Platform

The Short Answer

If your organisation actually uses 70%+ of Salesforce’s features and your workflows map naturally to its data model, stay on Salesforce. Customise it, optimise your licences, and make peace with the cost.

If you are using Salesforce as an expensive spreadsheet, fighting its limitations daily, or watching your per-seat costs climb while your team works around the platform rather than with it — it is time to consider a custom alternative. The cost difference is not marginal; it is typically 3-5x over five years.

Who This Is For

This guide is for enterprise leaders — CIOs, operations directors, or heads of technology — who are either evaluating Salesforce for the first time or questioning whether their current Salesforce investment is delivering value.

This is not for you if:

• You are a small business with 5-10 users (look at HubSpot, Pipedrive, or similar)
• Your Salesforce instance is simple and working well (do not fix what is not broken)
• You need a platform decision this week (this requires proper evaluation)

The Cost Reality Check

Let us do the maths that Salesforce’s sales team will not do for you.

Salesforce: The Full Picture

For a 50-user enterprise on Salesforce Enterprise Edition:

• Licences: £120-£300/user/month = £72K-£180K/year
• Salesforce admin (internal or contractor): £50K-£80K/year
• Ongoing consultant support for customisations: £30K-£60K/year
• AppExchange add-ons: £10K-£30K/year
• Initial implementation: £100K-£500K (amortise over 3-5 years)

Total cost of ownership over 5 years: £500K-£1.5M+

And that is before you hit the point where your customisations become so complex that you need a dedicated Salesforce architect at £1,000+/day.

Custom Platform: The Full Picture

For a purpose-built platform serving 50 users:

• Initial build: £40K-£150K (depending on complexity)
• Hosting (Vercel/AWS): £3K-£8K/year
• Maintenance and updates: £20K-£40K/year
• No per-seat licensing: £0

Total cost of ownership over 5 years: £150K-£400K

The gap is significant. Not every enterprise should optimise purely on cost, but you should at least understand what you are paying for.

When Salesforce Is the Right Call

Your sales process is complex and standard. If you have a multi-stage sales pipeline with forecasting, territory management, and CPQ (configure-price-quote) needs, Salesforce excels here. Rebuilding this from scratch would be foolish.

You need AppExchange integrations. If your workflows depend on five or six Salesforce-native tools (Pardot, Conga, DocuSign for Salesforce, etc.), the integration value is real.

Compliance requires a recognised platform. Some regulated industries and enterprise buyers specifically want to see Salesforce (or similar Tier 1 platforms) in your stack. If your customers’ procurement teams audit your tools, Salesforce ticks a box that custom cannot.

You already have a mature Salesforce org. If you have spent years building a well-architected Salesforce instance with clean data, good automation, and happy users — do not throw that away. Optimise it instead.

When a Custom Platform Is the Right Call

You are using 20% of Salesforce’s features. If your team uses Salesforce as a glorified contact database with some custom objects bolted on, you are massively overpaying. A custom build can replicate the parts you actually use for a fraction of the cost.

Your workflows do not fit Salesforce’s model. Salesforce is brilliant for standard sales processes. It is mediocre-to-poor for operations management, project tracking, inventory systems, or any workflow that does not revolve around accounts, contacts, and opportunities. If you are constantly fighting the data model, that is your signal.

Per-seat costs are becoming unsustainable. When you are paying £150/user/month for people who log in twice a week to update a status field, the economics are broken. A custom platform with no per-seat licensing changes the calculation entirely.

You want to escape vendor lock-in. Salesforce knows that migration is painful, and they price accordingly. If you have ever been in a Salesforce contract renewal negotiation, you know the leverage is not on your side. Vendor lock-in escape is something we handle regularly at LiberateWeb.

What a Custom Platform Actually Looks Like

This is not about building “Salesforce from scratch.” That would be absurd. It is about building the 20-30% of Salesforce that you actually use, tailored precisely to your workflows.

A typical custom enterprise platform we build includes:

• Contact and company management — your actual data model, not Salesforce’s
• Workflow automation — built around your processes, not configured within platform constraints
• Role-based access control — proper security without paying for Shield
• Reporting dashboards — exactly the metrics you need, not 200 standard reports you ignore
• API integrations — connect to your accounting, email, and other systems directly
• Audit logging — full traceability for compliance

Built on Next.js with Supabase and deployed on Vercel, this gives you a fast, modern platform that any competent React developer can maintain.

The Migration Path

If you are currently on Salesforce and considering a move, this approach works consistently:

1. Audit your actual Salesforce usage. Which objects, fields, automations, and reports are actively used? (You will be surprised how much is legacy clutter.)
2. Identify the highest-friction workflows. Where does your team work around Salesforce rather than with it?
3. Build the custom replacement for those workflows first. Run it alongside Salesforce.
4. Migrate users gradually. Team by team, not big-bang.
5. Decommission Salesforce modules as each is replaced.

This typically takes 6-12 months for a full migration, but you start seeing value (and cost savings) from month two or three.

Where We Stand

We are not anti-Salesforce. It is a powerful platform that dominates its market for good reason. But it is also grotesquely overpriced for many of the enterprises using it, and the customisation model creates a dependency on expensive specialists that compounds year after year.

If Salesforce is working well for you, optimise and stay. If it is a source of constant friction and escalating costs, let us show you what a custom alternative looks like. We have built several Salesforce replacements for enterprises and the reaction is almost always the same: “Why did we not do this sooner?”
