Custom software Vigo: when it makes sense and when it doesn't

There’s a comfortable narrative in the industry: “every serious business eventually needs custom software”. It’s false. Most Vigo SMEs with 5-15 employees don’t need it — what they need is to get their existing systems in order, or to swap one generic tool for another generic one that fits better.

When custom software in Vigo genuinely makes sense, the signs are concrete and measurable. When it doesn’t, the costs are brutal: months of development, a long stretch with no operational progress, and often a system the team ends up abandoning within a year.

The 5 signs your SME DOES need custom software

1. Your core process doesn’t exist in any tool on the market. If what sets you apart from the competition is precisely what standard tools don’t account for, this is you. A typical case in Vigo: fishing-sector companies with traceability logic that SAP doesn’t model, distributors with discount schemes that depend on customer history in ways no CRM lets you configure.

2. You use 3+ parallel spreadsheets alongside your official software. If your team keeps the operation running on parallel Excel sheets because “the system won’t let us”, that’s costing real time. Count how many hours a week go into keeping them in sync. If it’s more than 15h/week across the whole team, custom software pays for itself fast.

3. Errors cost you more than the solution would. Duplicate shipments, invoices issued with wrong data, stock committed twice to the same customer. If those errors are frequent and eat up hours of your team’s time (or annoy customers), a system of your own ends up paying off.

4. You need to integrate things the market doesn’t integrate. WhatsApp Business with your ERP. Your PrestaShop store with your 12-year-old accounting software. Your industrial scale with your delivery-note system. Custom integrations are one of the areas where bespoke consistently beats off-the-shelf.

5. You have a competitive edge you want to make hard to copy. If your internal process is part of your edge, putting it into a SaaS tool your competitors also use gives it away for free. Custom development here is a defensive move.

The 3 signs you DON’T need it (yet)

1. You haven’t tried fixing what you already have. Many SMEs call in developers when the real problem is that nobody has properly configured the ERP they already paid for. A consultant spending two days sorting out Holded, Sage or whatever you use can solve 70% of the pain for a fraction of the cost of custom development.

2. Your volume doesn’t justify the investment. If your annual turnover is modest, it’s hard for custom software to pay off against a well-assembled combination of existing SaaS tools. The exception is if the software itself becomes a sellable product for others (a different case).

3. Your team isn’t able to use what it already has. If nobody at your SME opens the reporting module of your current ERP, custom software won’t fix that. The problem isn’t the software, it’s the workflow. Training first, development second.

A real case: expense and receipt management for a Vigo SME

A team of 8 people who travel a lot (sales reps, technicians) piled up petrol receipts, meals, tolls, parking. The old process was: everyone kept their receipts in an envelope for the month, handed them to accounting on the last day, and one person entered them by hand, one by one, into the ERP. Errors, lost receipts, reimbursements that arrived late.

Why Holded/SumUp/others didn’t work: standard solutions make the user take a photo + categorise + upload. The team didn’t do it (too many clicks) and went back to the paper envelope.

What was built custom: an app that lets you photograph a receipt from your phone in 2 seconds. OCR extracts the amount, date and vendor. A model trained on the company’s historical expenses categorises automatically (petrol / meals / parking / other). At the end of the month, each rep reviews it in 5 minutes, approves it, and the ERP receives the entries ready to go.

Result measured after 3 months:

• Time spent on receipts by the admin team: from 6h/month to 45 min.
• Lost receipts: from ~12/month to 0 (if it’s saved instantly, there’s no envelope to lose).
• Team reimbursements within 48h instead of at month-end.

The most valuable part for the owner wasn’t the time the admin team got back — it was no longer being the bottleneck of the process himself.

How to decide in your case

If you have your own warehouse or handle logistics, you’re probably in the “YES” case — read the 3 patterns of logistics automation with concrete examples.

If you don’t know where to start, before hiring development ask for a digital consultancy that delivers a diagnosis with numbers, not a sales PowerPoint.

At Rowan Tech (Vigo) we do the diagnosis for free before proposing any development. If your case fits a product we already have — like the ERP for SMEs with logistics operations that we’ve designed specifically for this profile — we’ll suggest it. If your case is a “NO”, we’ll tell you so, backed by the numbers that prove it. Let’s talk.
