Most small businesses start with a spreadsheet, then move to a ready-made CRM. At some point the CRM starts to feel like it's in the way. Before you pay for a custom one, it helps to weigh ready-made vs custom CRM: when building your own is the right call, and when it isn't.
What each option means
- A ready-made CRM is a product you rent, usually per user per month. HubSpot, Zoho CRM, Pipedrive and Salesforce are well-known examples. You get a lot on day one, and you shape your process around the tool.
- A custom CRM is software built around your process. You pay to build it and to keep it running, and it belongs to you.
- In between, you keep a ready-made CRM and add a few custom parts: an integration, a form, a report or an automation.
When a ready-made CRM is enough
- Your sales steps are the usual ones: new lead, first call, proposal, won or lost.
- Your team is small, and the monthly price per user is easy to afford.
- You need something working this week.
- The tools you already use, such as email, calendar and accounting, connect to it.
When a custom CRM pays off
- Your process doesn't fit. For example, jobs with stages that only your trade has, price calculations, approvals, site visits, or records that aren't really "contacts" and "deals".
- Your team keeps growing. A ready-made CRM costs more with every user you add. A custom one costs money to build and maintain, but not for each extra person.
- It has to work with your own systems: your website's enquiry form, your POS or stock system, WhatsApp, or a database you already run.
- You need control over the data: where it is stored, who can see what, and what happens to it when you leave a provider.
- You pay for several tools just to work around gaps in one.
Questions to answer before you decide
- Write down every step from first contact to paid invoice. Which steps doesn't your current tool support?
- Who will use it, and what does each person need to see and change?
- Which systems must it exchange data with?
- What will each option cost over three years? For a ready-made CRM: the monthly price, times your users, times 36. For a custom one: building, hosting and maintenance. Get real quotes for both.
- Who will look after a custom system once it is built?
- Can you start small, with the three or four screens your team uses every day, and add to it later?
If you go custom
- Start with the screens your team uses daily, and bring your existing data in on day one.
- Insist on the basics of security: a login for each person, two-step verification, roles that limit what each person can see, and a log of every change.
- Plan backups, and test that a backup can actually be restored.
- Make sure the contract says the code and the data are yours.
