Automating reports from ERP, CRM and Excel
· by Panayot Dimkov
Automating reports is usually treated as a charting problem, and it is not one. The monthly report does not take three days because drawing a chart is hard: it takes three days because data has to be pulled from four systems, reconciled, investigated when it does not reconcile, recalculated and assembled again. The chart is the last ten minutes.
1Where the time actually goes
| Step | What happens in practice |
|---|---|
| Extract | Log into each system, run the extract with the right filters and export. If someone picks the wrong date range, the error travels all the way to the end |
| Reconcile | CRM sales do not match ERP sales. It is almost never a fault: they measure different things. Working that out every month is the invisible work |
| Calculate | Formulas in a spreadsheet someone built years ago. They work until a row is added outside the range |
| Distribute | Save, rename, attach, write the email. Five minutes repeated for each recipient and each corrected version |
The first two steps take most of the time and are exactly the ones invisible in the result. Whoever receives the report sees a neat PDF and assumes it produced itself.
2The problem nobody mentions
There is something worse than taking three days: the same figures coming out differently depending on who produces them. It happens as soon as two people build the same indicator with slightly different criteria.
Automation forces the definition to be written down: what counts as a sale, from when, at what exchange rate, including cancellations or not. That exercise is usually the project's real value, even though nobody asks for it.
3How to automate reports: the four layers
Almost every project that goes wrong starts at layer 4 and never reaches layer 2. The result is a very handsome dashboard nobody believes, and the following month people rebuild their spreadsheet.
4What to do about Excel
The answer is not to get rid of it. Excel is an excellent tool for analysis and a terrible one as a shared database. The distinction matters.
5The three expensive mistakes
- Automating a report nobody uses. Before touching it, ask who opens it and what they decide with it. It is surprisingly common to find the answers are "nobody" and "nothing", in which case the solution is to stop producing it.
- Automating on top of dirty data. If customer codes are duplicated in the CRM, the automatic report will reproduce the problem every month, but faster and with more authority.
- Building a dashboard instead of answering a question. A dashboard with forty charts does not get looked at. Three figures that answer a specific decision do.
6Where to start
Frequently asked questions
Do I need a business intelligence tool to automate reports?
Not necessarily. If the report ends up as a spreadsheet or a PDF sent by email, the flow can produce it without any additional platform. A dashboard tool earns its place when data needs to be explored interactively, not when the same report simply has to be produced each month.
Power BI or Excel for automating reports?
It depends on who uses the report and how. If it is a fixed table the team then works on in a spreadsheet, it is enough for the flow to deliver an updated Excel file. Power BI fits when several people need to filter and explore the data themselves, but sharing its reports generally requires a paid per-user licence for both whoever publishes and whoever views them. What matters is that layers 1 to 3 do not depend on the choice: the same reconciled base can feed both.
Can data be combined from systems that do not talk to each other?
That is the most common case and where most of the value sits. The difficulty is not technical but definitional: you have to decide which field links each record and what happens when there is no match. That decision belongs to whoever knows the business, not to the tool.
Who maintains this when something changes?
It is the right question and it should be answered at design time. If an automated report breaks every time someone adds a field in the CRM, it has not solved the problem, it has moved it. A good design fails visibly, raises an alert and can be repaired by someone other than its original author.
How long does it take to automate a report?
It depends mainly on how many sources have to be connected and what state the data is in. A report with a single source system and clear definitions is a short project; one that crosses three systems with different criteria needs the reconciliation work first, and that is where the time goes.
In short
Automating reports is not automating charts. It is solving extraction and reconciliation, the two invisible layers where the time goes, and finally writing down the definition of each figure.
With that work done, the report stops being a monthly task and becomes an output. And something better appears: once the data is connected and clean, building the next report costs a fraction of the first. That is how we approach AI process automation.
