Comparison · Custom CRM
"Build a custom CRM" used to mean a quarter of developer time. It now means an afternoon - which makes the interesting question not how but whether, and what the thing you build will cost you in year two. This compares the real routes, including the one where you don't build anything at all.
Disclosure: Chromoly is our own product. It appears on this list because it genuinely fits some of these jobs - and we've written a plain "don't pick us if..." line for the cases where it doesn't. Prices aren't quoted anywhere on this page: they change constantly and stale numbers help nobody. Every tool links to its own pricing.
Don't build if your process is contacts, deals, pipeline stages and activities. That is precisely what HubSpot, Pipedrive and Zoho were designed for and they do it better than your first attempt will. Rebuilding a solved shape is the most common expensive mistake in this category.
Do build when the record you actually manage isn't a deal - a matter, a project, a property, a candidate, a shipment, a member - or when your CRM needs to sit inside operations rather than beside them, or when a standard CRM covers about 70% and the missing 30% is the part that makes you different.
Best for: standard sales processes, immediately
Mature, well-supported, and full of things you would otherwise build badly - sequences, reporting, integrations, mobile. The default answer for a sales team selling in a normal shape.
Where it falls down: you adapt to their model. The customisation ceiling arrives exactly where your business is unusual, which is the part you most wanted to support.
Best for: the first version, and finding out what you need
Genuinely underrated as a starting point. Cheap, fast, and honest about being a table - and the constraints teach you what your real data model is before you commit to anything.
Where it falls down: multiple editors, change history, per-person visibility and anything that must happen automatically. Those four are database jobs, and pushing past them is where the hidden cost sits.
Best for: building inside an ecosystem you already use
If the business already runs on Zoho, building the custom piece next door keeps the data close and the integrations short.
Where it falls down: it deepens the commitment to one vendor's world, which is fine until it isn't.
Best for: a proper interface over a base you already maintain
A real step up from a shared spreadsheet: permissions, clean screens, client or team access, no code required.
Where it falls down: logic scattered across the base, its automations and the front-end - and nothing showing how those three depend on each other when you change something.
Best for: getting to something working extremely fast
Describe the CRM, get a working application. Genuinely impressive, and the fastest path from idea to screen that has ever existed.
Where it falls down: what you receive is a codebase, and hosting, security patching, monitoring and every future change are yours. Ask what happens the first time an edit breaks something you didn't know depended on it - see why AI-built apps break in production.
Best for: a custom CRM you'll still be changing safely in year two
Same plain-language starting point, different architecture behind it: the description becomes a blueprint that the system is compiled from, so a later change - renaming Customer to Client, adding an approval step, splitting a pipeline - is applied to the blueprint and shows you everything it affects before it goes live. The result runs on your domain, monitored, patched and maintained. See the custom CRM build.
Don't pick us if: you sell in a standard shape and just need a good CRM tomorrow. Buy Pipedrive. We're for the businesses that don't fit the shape.
Buy if your process matches what CRMs assume - deals, stages, contacts, activities. Build when the record you manage isn't a deal, or when the CRM must sit inside operations rather than beside them.
It's built around today's process and can't follow the business, so people drift back to spreadsheets - or the person who built it leaves and nobody can safely change it. Both are maintenance failures, not build failures.
Yes, in minutes. The meaningful differences are downstream: whether the next twenty changes are safe, whether anything tracks dependencies, and whether the result is maintained once real deals live in it.
Often, for a while. It stops being enough when several people edit it, when you need change history, when different people should see different rows, or when something must happen automatically.
