A sales database allows you to keep track of all your customers ' sales history, and at the same time you can analyse what data they have in common. Creating your database is essential for building customer loyalty and increasing your sales.

To do this, find out what you can achieve with your database and how to set it up in an easy way. So, take paper and pencil, and write down everything we are going to tell you.

What is a database for sales?

A database is a list of all the data of all the contacts who have bought, follow you on your social networks or are interested in your products or services. This list of data will have many benefits, as it allows you to analyse what purchases they make, what type of payment they use, what time of year they make them, if there are more or less online sales, etc.

Usefulness of a database

Your database will allow you to:

  1. Create a closer relationship with your customers, being able to contact them, offer them deals, find out what they want, etc.
  2. Not having to ask for all their details every time they make a purchase.
  3. Know which marketing campaign makes the most sense for you to use.
  4. Offer your customers promotions personalised to their tastes and/or purchases.
  5. Recover those customers who bought once and never bought again. This is done through direct marketing techniques, promotions, etc.
  6. Define your potential customer more easily.

Is it legal to buy databases?

The answer is yes. Marketing agencies and other companies can sell databases they have collected with information about certain customers. This can be done as long as it is stated that permission is given to "sell or transfer your data to third party companies".

What is the problem? These databases do not include data about your company or your current or potential customers. Much of the data you have paid for may be of no value but generic information.

How to create a database?

1. What data should it contain?

First, you have to think about what information to include. Here we show you the essential data:

  • Gender you identify with.
  • Age.
  • Address.
  • Purchases made.
  • Payment method.
  • Contact information.

It is also interesting to collect other information such as

  • Daily needs.
  • Possibility that your product or service could help them.
  • Means by which they are informed about products or services.

2. Where to look for information

Information can be collected using thousands of techniques. Here we recommend the most important and easiest ones to carry out:

  • General surveys of your ideal customers.
  • Information collected during the purchasing process.
  • E-mail marketing campaigns in which you send e-mails with specific information asking for more information.
  • Possibility of creating a section on the website, as partners, where they can register.
  • Social networking.
  • Offers or sweepstakes that require certain information to participate.
  • Information obtained from Google such as visits, type of user, geographical location, etc.

3. Use a CRM

Beyond an Excel database, a CRM (Customer Relationship Management) can help you a lot. Why? It allows you to mobilise and search for information directly from your customers. A CRM is a customer relationship manager that allows you to record all the information that interests you.
