Custom software or an off-the-shelf tool?

Not every problem needs a new system. Off-the-shelf tools are quicker to start with and spread development costs across many customers. If one of them fits your process well, it is usually the better choice, and I will tell you so in our first conversation.

When an existing tool is enough

When the process is common in your market, when the adjustments you need are small and when the subscription cost is low compared to what you gain from the tool. In those cases building from scratch means paying more to end up in the same place, only months later.

The sign that it stopped fitting

There is a simple test and it almost never fails: if someone on the team keeps a spreadsheet next to the system to make up for what it doesn’t do, the tool has already stopped fitting. That spreadsheet is where the real business rule ended up when it had nowhere else to go.

The same goes for the other workarounds: the notes field that became a database, the WhatsApp thread that is the only source of truth for an order, the report someone assembles by hand every month because the system exports almost what is needed.

Three rules that fit no existing tool

Kairo handles time tracking and hour balances. Each person’s schedule sets a day off, a number of hours or fixed times for every day of the week, and it accepts a substitute schedule on one specific day without dismantling the fixed one. The history shows, date by date, how many hours were short or over. It is worth checking whether your time tracker swaps a single day’s schedule without making you redo the week.

At Vippers, the operations team needs to draw the service areas on the map. The panel has a polygon editor much like Figma’s pen: expand, subtract, merge vertices and block overlap between areas. That is not something you buy separately — either it lives inside your system, or the team draws it on paper.

Also at Vippers, the price shown to the customer is made up of the fare, waiting time, a cancellation fee and discounts. Every business composes a price differently, and it is the kind of rule where a ready-made tool’s configuration options either fit exactly or do not fit at all.

The middle path

Most of the time the best answer is not replacing everything: it is keeping what works and building only the missing piece. Nails by Ivyy still uses Google Calendar and Instagram, and the system replaced neither. It simply started respecting the calendar’s appointments when working out free slots, and pulling Instagram posts onto the site, with the owner choosing which ones appear.

An integration between two tools that don’t talk to each other, a panel that gathers scattered data, an automation for the task nobody wants: it usually costs a fraction of a new system and solves the thing that actually hurts.

How to decide

Stay with the ready-made tool if the process is common in your market, the adjustments are small and nobody keeps a parallel spreadsheet. Consider custom if there is a rule the tool treats as an exception, if the team copies information between systems, if you pay overlapping subscriptions or fees per staff member, or if the process is part of what sets your business apart.

If you are unsure, the first conversation settles it: describe how the process works today and I will tell you whether what already exists can solve it. Pointing you to a ready-made tool when one fits is cheaper for you and avoids a project that did not need to exist.
