# How Do I Build a Customer Database From In-Store Purchases?

You build it by capturing a few key details at the counter, name, phone, and consent, through a very short form, and linking each purchase to that customer record. On **Jestor**, this runs through **Forms** connected to a customer **table**.

Stores that sell mostly in person often know little about their customers. Without contacts, there is no way to invite them back, announce new arrivals, or reward loyalty.

## What an empty customer list costs

- No way to reach customers after they leave
- Promotions that depend only on foot traffic
- No data on who buys what and how often
- Loyalty programs that cannot start

## How capturing in-store customers works

- A short **form** captures name, phone, and permission to contact
- Each purchase links to the customer record
- The list grows naturally with every sale
- Segments, such as frequent buyers, can be filtered

## Why Jestor fits this use case

- A short form keeps the line moving
- Linked purchases build a real history over time
- Consent is recorded alongside contact data
- This scales from one counter to many stores

| Cannot reach buyers again | Contacts and history grow with each sale |
