It works, until it doesn’t. The good news is that moving from Excel to a system no longer requires a year-long IT project or a six-figure budget. ## When is Excel no longer enough? Excel is an excellent tool for calculation and one-off analysis. Problems begin when it becomes the company’s information system. You can recognise the situation from these signs: - Several people edit the same file, and multiple versions are in circulation. - Data is entered by hand in two or three places, for example Excel, invoicing and email. - One person is the only one who understands the file’s formulas, and their holiday brings the process to a halt. - Errors are found after the fact: a row has gone missing, a formula has broken or an old version has ended up with a customer. - Nobody sees the overall picture unless someone compiles it by hand. If two or more of these sound familiar, the process is probably ripe for automation. This is not a flaw in Excel, but a sign that the process has outgrown its tool. The same applies to email and paper notes, which play the same role in many companies. ## Where should automation start? Not with everything at once. The best starting point is a process that repeats often, takes hours every week and has clear rules. Typical examples are handling quotes and orders, logging working hours or jobs, tracking inventory or equipment, and compiling reports for management. A good way to choose is to roughly count how many hours a month each piece of manual work takes and how often errors occur in it. The process with the most hours and errors relative to the clarity of its rules is usually the best first step. After the first success, the next targets are easy to find, because the organisation starts suggesting them itself. ## Does the system have to be a big project? No, and usually it should not be. The traditional approach, specifying for half a year and building for a year, is a poor fit for a small company: needs change before anything gets finished. A better model is to start from a narrow core, meaning the one process that causes the most headaches, and expand only once the core is in use. Modern software development has also sped up significantly now that AI-assisted tools handle the routine coding. For example, in Developit’s ai-ystävä service, custom software is delivered at a fixed price of 4,900 euros and is ready in two weeks. The point is not any individual figure but the scale: what used to be a months-long project is now weeks of work, which makes a custom solution a realistic option for a small company too. Custom software is not always needed either. Sometimes the right solution is off-the-shelf software, sometimes connecting existing systems so that data moves automatically from one place to another. The most important thing is to choose the solution based on the need, not the other way around. A concrete example helps with the scale. A typical first automation is, say, handling work orders: a customer’s enquiry is logged directly in the system, the job is routed to the right person, completion is confirmed and the invoicing data moves to finance without anyone copying rows by hand. A package like this is exactly the size that gets finished in weeks and pays for itself in saved working time. ## How do you avoid the typical pitfalls? The first pitfall is automating a messy process as it stands. If the current practice is unclear, the system will be unclear. Go through the process first and cut the unnecessary steps, as part of the manual work often turns out to be unnecessary already at this stage. The second is bypassing the people who do the work. The maintainer of the Excel file knows the process’s exceptions better than anyone else, and their knowledge belongs in the specification. The same person is also the best tester. The third is forgetting the old data. Agree right at the start what happens to the Excel history: is it migrated to the new system or archived in readable form. The fourth is leaving the rollout unsupported. Reserve time for onboarding and keep the old and new way running side by side for a while, so the transition does not disrupt daily work. ## How do you know which solution suits your company? If your company has an Excel file or a manual process that needs a successor, you do not have to solve it alone. Developit’s consulting goes through your process, helps you choose between off-the-shelf software, integration and a custom solution, and draws up a plan that proceeds in small, sure steps. If custom software turns out to be the right solution, our ai-ystävä service delivers it at a fixed price in two weeks.
