Keep customer information in one place
Customer details are spread across an inbox, a spreadsheet and someone’s phone, so nobody can answer a simple question without asking three people.

The problem
Customer information accumulates wherever it first arrived. The address is in an old email, the delivery preference is in a text message, the note about the difficult invoice is in someone’s memory, and the spreadsheet has a version on a laptop that was never merged back.
The daily cost is small and constant: a question that should take ten seconds takes five minutes and involves two people. The occasional cost is larger. Someone leaves and their inbox holds the only record of an arrangement. A customer repeats something they told you last month and you have no trace of it.
This is also a data protection problem hiding as an organisational one. If you cannot say where customer data lives, you cannot honour a request to see it or delete it, and you cannot secure it.
What AI can actually do here
The core is structure rather than intelligence: one record per customer, with fields that mean the same thing every time, in a place everyone can reach.
The mechanical gain is that structured fields refuse bad data. A date field will not accept a note, which is the failure mode that makes shared spreadsheets untrustworthy after a few months.
Where automation genuinely helps is capture: a form submission or an email creating or updating a record without retyping, so the single source stays current instead of decaying while a parallel copy grows in an inbox.
Enrichment and AI fields can fill in public company information and summarise, which saves time on business customers. Treat generated summaries as notes rather than facts, particularly anything you would repeat back to the customer.
Search across it is the payoff. The question is rarely complicated. It is which customers are in one region, or who has not ordered since spring, and that is trivial against structured records and impossible against an inbox.
How the tools differ
Airtable is the structured database that behaves like a spreadsheet, which is what makes it adoptable by people who will not learn a database. There is a free plan, Team is $20 per user per month billed annually and Business $45. Monthly pricing is not stated on their pricing page.
Notion is the better fit when customer records need to sit next to notes, documents and project pages rather than standing alone. Free for individuals with limited blocks for workspaces of two or more members, Plus EUR 9.50 per seat per month, Business EUR 19.50, with Notion AI included on paid plans.
Attio is the CRM end, and worth it when the records need workflows and enrichment rather than just storage. The free plan covers up to 3 seats, 3 custom objects, 50,000 records and 200 emails per month, Plus EUR 39 per user monthly or EUR 31 annually, Pro EUR 93 or EUR 74 annually.
Notion vs Airtable covers the first choice most people face.
When you don't need a tool
If you have thirty customers and one person deals with all of them, a well-kept spreadsheet is genuinely fine. The threshold is more than one person needing the same answer.
If the information is genuinely unstructured, notes about conversations rather than fields, a document per customer beats a database. Do not force structure onto something that does not have any.
For a pipeline of prospects rather than a record of customers, see keep track of leads and deals.

Frequently asked questions
Do I need a CRM or a database?
A CRM if the records drive a process with stages and follow-ups. A database if you mainly need to look things up and keep them accurate. Buying a CRM for storage means paying for a pipeline you will leave empty, which is the most common wrong turn here.
What does GDPR require of me here?
You need to know what personal data you hold, why, and for how long, and be able to provide or delete it on request. Consolidating into one place makes all of that possible rather than theoretical. Scattered copies in inboxes are the specific thing that makes a deletion request impossible to honour properly.
How do I migrate without losing anything?
Decide the fields first, then import the largest existing source, then add the rest by hand as customers come up. Trying to merge every source in one pass is where these projects stall. Anything not touched in a year probably does not need migrating at all.
Who should have access?
Everyone who needs to answer a customer question, which is usually more people than currently can. Restrict the sensitive fields rather than the record, because access restricted at the record level is what drove the information back into private inboxes in the first place.
