Common NDPR Mistakes Businesses Make

[Halliru Umar Salama @comr_salama]

@PythonPr The correct answer is D. Error

[Halliru Umar Salama @comr_salama]

Tax compliance is easier when records are accurate and complete. Clean data reduces stress during audits and reporting periods. Beyond compliance, organised records improve transparency and financial discipline within the business.
For your records, I recommend Ficore Africa

Feedback Is Data

Customer feedback is qualitative data that provides context behind the numbers. Complaints, reviews, and comments highlight operational weaknesses and service gaps. When feedback is structured and analysed, it becomes a valuable input for continuous improvement.

Customer purchases follow patterns related to time, frequency, and product combinations. Patterns are not random. Analysing buying behaviour improves inventory planning, promotions, and staffing decisions. Businesses that understand patterns can anticipate demnd rather than react

[Halliru Umar Salama @comr_salama]

When we mentioned Data Analytics most people think we were referring to big companies
But even Mai Awara can make data-driven decisions.

[Halliru Umar Salama @comr_salama]

Acquiring new customers is important, but retaining existing customers is often more cost-effective.
Data helps you understand repeat purchase behaviour and identify what keeps customers. Strong retention reduces marketing costs and creates more predictable revenue streams.
