Are You Still Tracking Your Customers in Excel? The 'Hidden' Mistake Costing Your Business Money Every Month

Are You Still Tracking Your Customers in Excel? The 'Hidden' Mistake Costing Your Business Money Every Month

"It is not unemployment that sinks companies, it is 'lack of tracking'."

Your phone rings. It's an old customer calling or a potential buyer. At that moment, these questions turn in your head: 'When did we last give a price to this person?', 'Did we receive their payment?', 'Where did I take the note; to Excel, to Whatsapp, or to the paper on the table?'

Every second you spend looking for that information creates a 'loss of trust' on the other side. Even worse; every untracked offer is cash left on the table. Many business owners say, 'Our business is not that big, Excel is enough for us'. But as Nexentio, with our 6 years of experience, we can easily say this: It is not unemployment that sinks companies, it is 'lack of tracking'. Here are 4 critical reasons to leave the 'Grocer's Notebook' or Excel method and switch to a custom CRM (Customer Relationship Management) system.

1. Don't Let Your 'Memory' Depend on Your Staff (Corporate Memory)

What happens when your sales representative or secretary leaves the job? Do customer information, special notes, and past interviews go with them? Excel files can be deleted, notebooks can be lost. CRM Solution: In a private CRM software, your data is stored in the cloud. Even if the staff changes, the customer's order from 3 years ago or special request is registered in the system. Your company grows based on the system, not individuals.

2. Sales That Do Not 'Follow Up' Cannot Be Made (Automatic Reminders)

According to statistics, it takes an average of 5 meetings to close a sale. So, how do you remember who to call when? Notes like 'I'll call you next week' lost among papers are actually money thrown in the trash. CRM Solution: Smart systems send you a morning notification: 'You need to call Mr. Ahmet today, he asked for a price last week.' Thus, you do not let any opportunity slip through your fingers.

3. Make the Customer Feel 'Special'

Think of a dental clinic or shipping company. There is saying 'Go ahead sir' when the customer calls; there is saying 'Hello Mr. Mehmet, were you satisfied with your treatment last month? Your spouse's birthday is approaching, would you consider a gift?'. CRM Solution: The business that knows the customer always wins. On the CRM screen, you see the customer's entire history in seconds, you speak accordingly. This is the clearest step from amateurism to professionalism.

4. Stop Laboring, Switch to Automation

Are you still cutting invoices by hand, preparing offers one by one in Word and converting them to PDF? Your time is valuable. These operational tasks prevent you from building strategy. CRM/ERP Solution: You can create an offer with a single button, send automatic payment reminder emails. While you sleep, your system celebrates the customer's birthday or reminds them of their appointment.

Conclusion: Take Back Control of Your Business

Getting lost among Excel spreadsheets is not suitable for the trade understanding of 2024. If you want to grow your business, you must first strengthen your 'Digital Backbone'. As Nexentio, we do not sell ready-made jackets that are 'too big' for you. We analyze the working style of your business (shipping, health, service, etc.) and produce 'Tailor Made' (Custom) software.
