About Marksyte
I trace every monthly number back to the files that produced it
I compare the files your retailers, distributors and ERP teams send. When EAN 8412345678918 shows 86 units in one file and 91 in the other, I trace the difference to its cause and leave a process your team can repeat.
Marksyte delivery modelEach review has one named owner, from source files to handover
What I bring
I write the rules down so the work stops living in one person's head
The method behind this page is public. It lives in the blog I write on retail and distributor data, by the same person who runs the reviews.
Agree what each number means
I write the rules out of real cases: SKU-8918 maps to EAN 8412345678918, customer CUST-042 maps to store ES-042
Work inside the systems you already use
I connect the Excel files, ERP exports and partner reports you have today, no new platform and no six-month build
Leave a process, not a dependency
Every rule, owner and open exception lands in a working document, so the cycle survives without me
How Marksyte publishes
How Marksyte publishes practical guides
Marksyte publishes practical material about FMCG retail data, reconciliation, mapping, data quality and recurring data operations. Operational examples are illustrative unless stated otherwise, external factual claims are sourced where appropriate, and the methods reflect Marksyte’s operating approach. Articles may be updated when methods, examples or source material change.
“Fourteen distributors sent fourteen file formats. I mapped them to one schema, and the monthly close went from three days to one morning.”
How I work
Honest about scope, rigorous about evidence
I start from the report you cannot explain
One monthly figure, one recurring mismatch or one hand-off between teams; I begin with the evidence
I work with the tools you already have
I design inside your Excel, ERP and BI, and I say clearly what I do not do
I document for continuity
Each rule, assumption and open exception gets an owner, so the work never depends on one person
Best-fit work
You know it is a fit when one of these sounds like your month
You rebuild the same workbook every month
And nobody can reproduce last month's number from the saved inputs and rules
Two partners call the same product differently
One file says EAN, another says SKU, and the mapping lives in someone's inbox
Sell-out and ERP disagree
And the 5-unit gap on EAN 8412345678918 gets fixed “when there is time”
Automation or AI needs trusted inputs
And you cannot prove which version of the data produced the result
