Spreadsheets work until they don't
Many small businesses track stock in a spreadsheet for years without problems. It works when there is one person, one location and a handful of products.
The cracks appear with growth: a second location, a second person updating stock, an online store alongside a physical shop, or suppliers with different lead times.
At that point, the real cost of a spreadsheet is not its price — it is the stock discrepancies, duplicate orders and manual reconciliation it causes.
What proper inventory software should do
Real-time stock levels
Every sale, return or delivery should update stock immediately, visible to everyone who needs it.
Multi-location and multi-channel tracking
If a business sells in-store and online, stock should be tracked as one pool, not two separate counts that drift apart.
Low-stock alerts
Automatic alerts when a product nears a reorder threshold prevent both stockouts and emergency orders.
Supplier and purchase order management
Tracking what has been ordered, from whom and when it is expected reduces manual follow-up.
Reporting
Which products move fastest, which tie up cash sitting on a shelf, and which are close to expiry or obsolescence — all this should be visible without manual counting.
Integration with the rest of the business
Inventory data is most useful when it talks to sales, the website and accounting, rather than living in isolation.
Off-the-shelf tool or custom system?
Off-the-shelf inventory tools are a reasonable starting point for a single, simple shop. They become limiting once a business has a specific workflow — a particular combination of locations, product variants, suppliers or sales channels that the tool was not built for.
A custom system is worth considering when the business is forcing its real operations to fit a generic tool's assumptions, rather than the other way around.
What does custom inventory software cost?
Scope depends on the number of integrations, locations and reporting needs.
At AgüíTech, inventory and stock management systems commonly range from €5,000 to €15,000+, depending on complexity.
Build the system around how the business actually operates
Inventory software should remove manual counting and guesswork, not add another tool to double-check.
