CRM Build Options: DIY, Bespoke or Dedicated

Most firms looking at a new CRM are weighing the same three routes, whether or not they say so out loud. None of them is wrong. They suit different firms, and they break in different places.

What does building it yourself involve?

Full DIY means vibe-coding your own system from scratch, or stitching together spreadsheets, forms and AI tools until it works. It is a realistic option in a way it was not two years ago, and for a small team with a technical person who enjoys it, it can be the right call.

• Who it suits: a very small team, with one technical person who will own it and enjoys doing so.

• What it really costs: little in software, a lot in someone's time. And the time does not stop once it launches.

• Where it breaks: when it needs to be trusted by everyone, or maintained by someone other than its builder.

What about everyone just using Claude?

More and more, people at a firm are doing their own thing with AI: one person's research workflow, another's note-taking, someone else's email drafts. That is useful. But a handful of individual setups is not a shared record. The firm still needs one place where relationships, deals and history land, whoever captured them and with whichever tool.

What is a bespoke build?

A custom build inside a flexible platform. For me that platform is Attio: the foundations are already there, and the data model, workflows and connections are designed around how your firm actually works, rather than the other way round.

• Who it suits: a firm whose process is its own, with relationships at the centre, that wants a system it controls without building one from scratch.

• What it really costs: a monthly platform subscription, plus an initial setup before it is useful.

• Where it breaks: when nobody owns it afterwards, or when a firm wants no setup at all. Good builds come with a clear handover and a plan for keeping the system current.

What do dedicated platforms offer?

Dedicated platforms are products built for one kind of firm, fully configured, with onboarding included. You get a working system quickly, and someone else carries the product roadmap.

• Who it suits: a firm that fits the template closely, has the budget, and is comfortable with a long contract.

• What it really costs: a higher subscription, often on longer terms, in exchange for not having to build anything.

• Where it breaks: when your process does not match theirs, because customisation is limited. And leaving later can become a project in itself.

How do I choose?

• Start DIY if you have a small team, one technical person with time to spare, and nothing that depends on the system being perfect yet.

• Go bespoke if your process is your own, relationships are the asset, and you want something working in weeks that you control.

• Go dedicated if your firm fits a ready-made template, you want a vendor to call, and you are happy to commit for the long term.

Plenty of firms try one route first and move to another. That is fine. Whichever you choose, make sure your data can come with you.
