Custom CRM vs Salesforce vs HubSpot — Which Is Right for a Small UK Business?

Most small UK businesses that need a CRM face the same decision: pay for Salesforce or HubSpot and adapt your processes to fit their system, or build something custom that works exactly the way your business works. Both answers are right in different situations. Here is an honest breakdown of when each option makes sense — without a sales pitch for any of them.

What Salesforce and HubSpot are actually built for

Salesforce was built for enterprise sales teams. It is extraordinarily powerful, deeply customisable, and priced accordingly — plans start at £20 per user per month and scale to hundreds of pounds per user once you add the features most businesses actually need. HubSpot started as a marketing platform and expanded into CRM. Its free tier is genuinely useful, but the features that make it a proper CRM — deal pipelines, reporting, automation — sit behind paid tiers starting at £41 per month and rising steeply. Both platforms were designed around a specific sales methodology. If your business works differently — if your customer journey does not map to their pipeline stages, if your terminology is industry-specific, if your team needs to track information these systems were not designed to track — you spend significant time and money configuring them to fit.

What a custom CRM actually is

A custom CRM is a web application built around exactly how your business manages its customer relationships. It tracks the data you need to track, uses your terminology, enforces your business rules, and produces the reports that help you make decisions. It does not have features you do not need. It does not require configuration to fit your workflow because it was built around your workflow from the start. The cost is a one-time build cost — after that, there are no monthly licence fees, no per-user charges, and no price increases when the vendor decides to move features to a higher tier.

The honest comparison

Salesforce and HubSpot win when you need out-of-the-box integrations with dozens of third-party tools, when you need a system your team already knows how to use, or when your sales process closely matches their standard pipeline model. A custom CRM wins when your process is specific enough that the configuration cost of a generic tool would exceed the build cost of a bespoke one, when you are paying for features you do not use, when monthly fees are significant relative to the value you get, or when the system needs to integrate with something the generic tools do not support. For most UK small businesses with a specific, well-defined customer management process, a custom CRM built around their exact workflow is cheaper over three years than a Salesforce or HubSpot subscription — and works better from day one.

What to consider before deciding

The right question is not "which CRM should we use?" It is "what does our customer management process actually look like, and how well does each option fit it?" If your process is standard — leads, pipeline, deals, won/lost — a well-configured HubSpot free tier will serve you well. If your process is specific — you track different information, use different terminology, need different reports — the configuration cost of making a generic tool fit often exceeds the cost of building something that fits from the start.
