what is a customer file And why is it essential for your prospecting?
Un customer file is the backbone of any business activity. It's a centralized database that gathers all the information relating to your customers and prospects: full contact details, history of interactions, amounts purchased, quotes sent, contrats Signed documents, relationship status, and any other information useful for personalizing your interactions. For a very small business or a small to medium-sized enterprise, the customer file is the tool that makes the difference between random prospecting and a structured and repeatable sales approach.
Many entrepreneurs start with a customer file in Excel or Google Sheets: a spreadsheet with columns for name, surname, email, phone number, and company. It's better than nothing, but this approach quickly shows its limitations. The Excel file isn't collaborative in real time, it doesn't connect to your emails, it doesn't generate automatic reminders, it doesn't tell you when a customer has opened your latest quote, and it can't trigger a billing automatic after an order. That's why companies that want to seriously structure their prospecting switch to a customer file software — or CRM — like Djaboo.
With Djaboo, your customer database becomes a living tool: each customer record not only contains contact information, but also the entire sales journey—from the first contact to the payment of the last invoice. Your employees see the same level of information, regardless of who handled the case. And thanks to the customer portal Integrated, your clients can access their documents, invoices and progress reports themselves — without having to ask you every time.
Total centralization
One place for all customer information: contact details, exchanges, documents, sales history. No more juggling Outlook, Excel, and handwritten notes. Every team member works from the same source of truth.
Segmentation & Targeting
Segment your customer database by industry, location, status, average order value, or any other custom criteria. Precisely target your marketing efforts and send the right message to the right person at the right time, without any manual effort.
Business continuity
Your customer file is no longer a static list but a sales engine: automatic follow-ups, quote tracking, alerts on stalled opportunities, and direct conversion to invoicing and projects. Each action generates the next.
Excel customer file vs. client file software
Spreadsheets have served their purpose, but they aren't designed to manage a growing customer relationship. Here's why structured businesses choose a dedicated tool.
Each client, a file
complete 360°
In a traditional customer file, you have contact information. In Djaboo, you have the complete file: who this customer is, how you met them, what you sold them, what they owe you, the contrats ongoing and important exchanges.
When a client calls, you have the complete context in less than 3 seconds. When a colleague takes over a case, they start from scratch under optimal conditions. Information no longer depends on a single person—it belongs to the entire team.
Segment your file
to target your actions
An unsegmented customer file is like a shopping list without order: you end up treating everything the same, without priority. In Djaboo, you can filter your database in just a few clicks to isolate hot leads, inactive customers (for 6 months), companies in a specific sector, or those with an average order value above a certain threshold.
These segments become the starting point for your retargeting campaigns, personalized offers, or loyalty initiatives. You focus your sales energy where it has the best chance of converting—and you let Djaboo handle the follow-up automatically.
Import your existing database
Do you already have a customer file in Excel, another software program, or your email? Don't worry. Djaboo imports your database in just a few clicks: select your CSV or Excel file, map your columns to Djaboo fields, preview the data, and confirm. In less than 5 minutes, your customer file is ready to use.
There's no need to wait for perfection before starting the import. The Djaboo philosophy: enter your data, start working, and enrich it as you use it. A file that's actively used is always better than a perfect file that just sits in a drawer. And you can export your data at any time—your contacts are yours to keep.
How to build a efficient customer file ?
A good customer database isn't built in a day, but with the right practices, it quickly becomes your most valuable business asset. The first rule: define the information that's truly useful for your business before importing anything. There's no point in having 50 fields if you only use 8 regularly. A small, up-to-date database is preferable to an exhaustive but outdated one.
The second rule is consistency. Your customer file should never stagnate. Every call, every email, every meeting must be updated in Djaboo—even if it's quick and brief. A two-line note after a call is worth more than a comprehensive report ever written. This daily discipline is what makes a customer file valuable in the long run.
Finally, remember to qualify your contacts. A file with 5,000 unqualified addresses is less useful than a database of 500 well-informed contacts. In Djaboo, tags and statuses allow you to maintain this level of qualification at all times: a contact who hasn't responded to three follow-ups automatically becomes "Inactive," freeing up your energy for more promising opportunities.
Customer file and GDPR compliance
In France and the European Union, the creation and use of a customer file are regulated by the General Data Protection Regulation (GDPR)In practical terms, this means that you must have a legal basis for collecting data from your customers and prospects, that you must inform them of its use, and guarantee them the right to access, modify and delete their data.
Djaboo simplifies this compliance: your data is hosted in France on certified servers, you are the sole owner of your database, and you can export or delete any data at the request of a contact. customer portal Djaboo also allows your customers to access and verify their own data independently.
For B2B prospecting, the GDPR is less restrictive than for B2C, but it remains essential to respect the right to object and not retain data unnecessarily. In Djaboo, you can set up automatic retention rules and properly archive contacts who no longer wish to be contacted—while still keeping the sales history for your accounting.
From the customer file to the billing in one click
The real advantage of a customer file in Djaboo compared to a simple spreadsheet is the seamless flow of business. From a customer's record, you can directly create a quote, send an invoice, or sign a contract—without re-entering any information. All the data (name, address, pricing terms) is automatically pre-filled.
Each generated document is automatically linked to the customer record and visible in the history. You can see at a glance how much revenue this customer has generated since the beginning, which invoices are pending payment, and which contracts are approaching their renewal date.

What they say about their Djaboo customer file
“Before Djaboo, my customer file was an Excel spreadsheet with 800 rows that were impossible to sort. Now I have complete records, I can see in 2 seconds what each customer has brought me, and I automatically re-engage inactive customers. I've reconnected with 3 customers I had completely forgotten about.”
"What appealed to me was that my customer file is linked to the invoicing system. I create a quote from the customer record, they sign it, I generate the invoice—everything is linked. No more re-entering information, no more errors in contact details. It easily saved me 4 hours a week."
“There were three of us salespeople working on the same Excel file, constantly getting in each other’s way. With Djaboo, everyone has their own view, we can see each client’s history, and the manager tracks performance in real time. Adoption was very rapid; everyone was using it in less than a week.”
