Short answer: to move from spreadsheets to a system without stopping the operation, don't replace everything at once. Start with the process that costs the most, clean up the master data, run the system in parallel with the spreadsheet until the numbers match, and only then retire the spreadsheet. Then add the next process.
The spreadsheet got you this far
The spreadsheet isn't the problem. It is the tool that let the company grow, and it often holds years of decisions. The problem appears when the company grows faster than the spreadsheet:
- There are several versions of the same file and nobody knows which one is right.
- Stock on file and stock in the warehouse never match.
- Monthly reports are built by hand and take days.
- Orders come in by WhatsApp, email and phone, and some get lost.
- If the person who maintains the spreadsheet goes on holiday, operations suffer.
Step 1: choose where to start
The first process to digitise is the one that costs the most today, in hours, errors or lost money. It might be order intake, stock control or production planning. Starting there means the first stage justifies itself and the team sees the benefit quickly.
Step 2: clean up master data
Before migrating, clean the data everything else depends on: customers, products, suppliers, price lists and opening stock. This is the moment to merge duplicate codes and names spelled three different ways. A new system with messy data repeats the spreadsheet's problems.
Step 3: run in parallel
For a period, the system and the spreadsheet coexist. The same movements are entered in both and totals are compared: stock, orders, production. When the closings match, the company has evidence it can trust the system, and a date is set to retire the spreadsheet.
Running in parallel takes some extra work, but it is far cheaper than discovering an error after the spreadsheet is gone.
Step 4: design for whoever enters the data
A system isn't measured by what it does in the demo, but by what happens when the shift starts and the day's production has to be logged. If the screen asks for twenty fields, the floor goes back to paper. That's why we map the process with the people who do it every day: which data they enter, in which order and how much time they have.
Step 5: train by role
Each person only needs to learn their part: operators their entry screen, the warehouse its stock movements, management its reports. Short, role-based training works better than a general system presentation.
Step 6: add the next process
Once the first stage is stable, the next process is added on top of what already works. The company is never in the middle of a total overhaul, and each stage carries limited risk. In our projects, the first version is usually in production within 2 to 4 months, with a working demo every two weeks.
In short
- Don't replace everything at once: start with the costliest process.
- Clean master data first, then migrate.
- Run system and spreadsheet in parallel until the numbers match.
- Screens designed for whoever enters the data, and role-based training.
