Alright, so you’re trying to figure out how to design CRM tables? Yeah, I’ve been there — it’s not as straightforward as it sounds. At first glance, you think, “Hey, just store names and emails, right?” But then reality hits, and you realize your CRM needs to handle way more than that. So let me walk you through this like we’re having a chat over coffee.

First off, you gotta start by asking yourself: what do we actually need to track? I mean, every business is different. Are you dealing with leads, customers, support tickets, sales pipelines? All of the above? That matters. Because if you don’t nail down the scope early, you’ll end up with a mess later.
So here’s what I learned the hard way — begin with the core entities. For most CRMs, that means Contacts, Companies, and Deals. These are your building blocks. Think of them like the foundation of a house. If they’re shaky, everything else collapses.
Let’s talk about Contacts first. You’d be surprised how many people forget to include basic stuff like job title or phone number. But also, don’t go overboard. I once saw someone add 50 fields for each contact — including “favorite color” and “pet’s name.” Come on, man, keep it professional. Stick to what’s relevant: name, email, phone, role, maybe LinkedIn URL. And definitely include a unique ID — trust me, you’ll thank yourself later.
Now, Contacts usually belong to a Company, right? So you need a Companies table. It should have things like company name, industry, website, address, and size. Oh, and link it back to Contacts using a foreign key. That way, when you look at a company, you can see all the people associated with it. Super useful for account-based selling.
Wait — speaking of linking, relationships between tables are crucial. Don’t treat them like an afterthought. Use proper foreign keys. I know some folks try to store related data as text — like putting a company name directly in the Contact row. Big mistake. What happens when the company rebrands? Now you’ve got outdated info everywhere. Normalize your data, please.
Okay, next up: Deals. This is where your sales team lives. Each deal should have a name, value, stage (like “prospecting” or “closed won”), and expected close date. And again, link it to both a Contact and a Company. Maybe even assign it to a User — because accountability matters.
But hold on — stages change, right? So instead of hardcoding stage names into the Deals table, create a separate Stages lookup table. That way, if marketing decides to rename “negotiation” to “final review,” you just update one place. Much cleaner.
And timelines! People forget about history. You want to know when a deal moved from “proposal sent” to “demo scheduled.” So consider adding an Activity or Deal_Stage_History table. Every time a stage changes, log it with a timestamp. Suddenly, your reports become way more insightful.
What about communication? Emails, calls, meetings — those are gold. Create an Activities table. Include type (call, email, meeting), subject, notes, who it was with, and when. Link it to the relevant Contact and Deal. Your sales reps will love being able to see the full conversation history.
Tags? Yeah, those are handy. Instead of cramming everything into categories, use a tagging system. Create a Tags table and a junction table to connect tags to Contacts or Deals. Flexible, scalable, and easy to filter later.
Custom fields? They’re tempting, but dangerous. I get it — every department wants their own special field. But if you let everyone add whatever they want, your database turns into spaghetti. If you must support custom fields, build a proper key-value structure or use JSON columns — but only if your database supports it well.
Don’t forget permissions. Not everyone should see everything. Maybe support staff shouldn’t view deal values. So think about access levels early. You might need a Users table with roles, and then enforce visibility rules in your app logic.
And indexing — boring, I know, but important. If your CRM slows to a crawl when searching for a client, nobody’s happy. Index the fields you search on most: name, email, company ID. Small effort, big payoff.
Backups? Always. Design with recovery in mind. Make sure your table structure allows for clean exports and restores. I once lost three days of data because someone deleted a table. Never again.
Lastly, keep it simple at first. You don’t need every feature day one. Start with the basics — Contacts, Companies, Deals, Activities — and expand as you learn what works. Iterate. Talk to your users. See where they struggle.
Oh, and document everything. Not just for others — for future-you. When you come back six months later wondering why you named a column “cust_ref_id_v2,” you’ll wish you’d left a note.
Look, designing CRM tables isn’t rocket science, but it does take thought. Take your time. Sketch it out on paper first. Whiteboard it with your team. Argue a little — good ideas come from debate.
And remember — it’s not about perfection. It’s about building something usable, flexible, and reliable. Get that right, and your CRM becomes a tool people actually want to use.
