A logistics or transport company with a growing warehouse operation quickly reaches the same conclusion: a proper Warehouse Management System is no longer optional. Paper-based processes and spreadsheets stop scaling the moment your team grows, your throughput increases, or your clients expect real-time visibility into their stock. The question is no longer whether to invest in a WMS, it is how, and at what cost.
This article breaks down three routes: fully custom development, off-the-shelf SaaS platforms, and low-code app development using platforms like Glide. The numbers might surprise you.
What a Modern SME Warehouse App Actually Needs
Before comparing options, it is worth being specific about the feature set we are talking about. A genuinely useful WMS for a logistics or transport SME typically needs to deliver:
- A native mobile app running on both Android and iOS, usable on cheap hardware with no specialist setup
- Multiple user types, warehouse operatives, supervisors, administrators, and clients, each seeing only what they need to see
- Role-Based Access Control (RBAC) so that permissions are enforced at a system level, not by trust
- A client-facing portal where customers can view the status and location of their goods without calling the office
- Product images attached to inventory records, so operatives can visually confirm the right item before scanning or moving it
- Native barcode scanning via the mobile app, so warehouse staff can record stock movements with a phone camera rather than a separate scanner
This is a real, commercially useful feature set. Not an enterprise wish list, just what a well-run logistics operation genuinely needs. Let us look at what each approach costs to deliver it.
Option 1: Fully Custom Development
The traditional route is to commission a bespoke application: a development agency or in-house team designs and builds exactly what you need, from scratch, owned entirely by your business.
Build Cost
A native mobile app with full RBAC, a client portal, image storage, and barcode scanning is not a trivial build. You are looking at a minimum team of two to three engineers, typically a backend developer, a mobile developer, and a project lead or QA resource. At Irish and Western European day rates (€450–€650 per day for a mid-to-senior developer), a project of this scope takes at least two to three months of elapsed time.
Realistic build budget: €75,000 – €120,000+
That range covers a realistic engagement with a competent agency or contractor team. Scope creep, integration work, testing, and deployment easily push the number toward the top of the range or beyond. If you need a custom backend, a proper CI/CD pipeline, and an App Store submission process, add more.
Ongoing Maintenance Cost
Custom software requires ongoing maintenance. Operating systems change. Libraries become deprecated. Security patches are needed. Bugs appear in edge cases. The standard industry estimate for annual maintenance cost is 15–20% of the initial build cost per year.
At a €90,000 midpoint build cost, that is €13,500–€18,000 per year in maintenance, every year, indefinitely. This requires either retaining the original developer on a support contract or bringing new developers up to speed on your codebase, both of which carry cost and risk.
| Cost Item | Custom Development |
|---|---|
| Initial build (2–3 engineers, 2–3 months) | €75,000 – €120,000+ |
| Annual maintenance (15–20% of build) | €11,250 – €22,500 / yr |
| 5-year Total Cost of Ownership | €131,000 – €232,000+ |
For the vast majority of Irish logistics SMEs, this is simply not viable. A €75,000+ upfront investment in software, before you have a single pallet moved through the new system, is prohibitive. Custom development remains the preserve of businesses with significant technology budgets, or those who have tried everything else and have no other option.
Option 2: SaaS Platforms
The obvious alternative is a Software-as-a-Service solution: pay a monthly subscription for a pre-built WMS that someone else maintains. On paper, this addresses the capital cost problem entirely, you pay as you go and the vendor handles the infrastructure.
The Reality of SaaS Pricing
Established WMS platforms aimed at SMEs are not cheap once you get past the entry-level tier. Oracle NetSuite, one of the most commonly cited platforms, starts at approximately €800 per month for the base licence, plus €80 per month per additional user.
A modest logistics operation with ten users is looking at €800 + (9 × €80) = €1,520 per month, roughly €18,240 per year. A team of fifteen users pushes this to €21,600 annually. And you own nothing at the end of it.
The deeper problem with SaaS: The pricing is painful, but it is not even the main issue. The real problem is fit. SaaS platforms are built to serve thousands of different businesses in hundreds of different sectors. They are necessarily generic. Most SMEs find that a standard WMS platform covers perhaps 70–80% of what they actually need, and the remaining 20–30% requires either expensive customisation, a workaround that creates new manual work, or a change to your business process to accommodate the software's limitations.
That last point is the hidden cost that never appears in a vendor demo. You spend months adapting how your business actually operates in order to fit the constraints of a platform you are paying €18,000 a year to use.
| Cost Item | SaaS (e.g. Oracle NetSuite) |
|---|---|
| Initial setup / implementation | €0 – €5,000 |
| Monthly licence (base + 10 users) | €1,520 / month |
| Annual cost (10 users) | €18,240 / yr |
| 5-year Total Cost of Ownership | €91,200 – €96,200+ |
| Ownership at the end | None. Cancel and it's gone. |
Option 3: Low-Code App Development with Glide
There is a third option that most logistics businesses have not seriously considered, not because it does not work, but because it is less well known than the other two. Low-code platforms like Glide allow a developer (or a well-configured non-developer) to build a fully functional, custom mobile application in days or weeks rather than months, at a fraction of the cost of either custom development or enterprise SaaS.
Why Glide Works for Warehouse Operations
Glide is particularly well suited to logistics and warehouse use cases because it was designed around exactly the kind of structured, mobile-first workflows that warehouse operations run on. Out of the box, Glide supports:
- Native barcode scanning using the device camera, no additional hardware needed
- Image storage per inventory record, attach photos of products, damage reports, or delivery confirmations
- Full RBAC, define roles (Operative, Supervisor, Administrator, Client) and control exactly what each role can see, edit, and submit
- Client portal views, give customers a read-only view of their stock status via a shared link, with no login friction
- Native Android and iOS apps via the Glide app player, or a Progressive Web App that installs from any browser
- API integrations, connect Glide to your existing systems (accounting software, transport management systems, ERPs) as your needs grow
What Does It Cost?
The setup cost for a well-specified Glide warehouse management app, with full RBAC, barcode scanning, image upload, client portal, and multiple user types, typically falls in the range of €2,000 to €5,000, depending on complexity and the number of integrations required.
The ongoing Glide platform subscription for the tier required by a commercial logistics operation is currently approximately €170 per month, covering unlimited users at the Business tier. There are no per-seat charges. Ten users costs the same as two users.
Future-proof by design: Because Glide apps are built on a structured, maintained platform, small changes and new features are straightforward to add over time. Need a new report? A new user role? An API integration with a new carrier? These can typically be done in hours rather than days, by someone with Glide knowledge, including your own team after a brief training session. You are not locked into paying an agency for every minor change.
| Cost Item | Low-Code (Glide) |
|---|---|
| Initial build (fully custom to your workflow) | €2,000 – €5,000 |
| Monthly platform subscription | ~€170 / month |
| Annual running cost | ~€2,040 / yr |
| 5-year Total Cost of Ownership | €12,200 – €15,200 |
| Per-seat charges | None. Unlimited users. |

A Real Example: Target Transport Services, Dublin
Target Transport Services is a Dublin logistics company that was managing its warehouse operations using a combination of spreadsheets and manual paper records. Stock movements were tracked by hand, client queries required staff to dig through paperwork, and inventory accuracy was a persistent problem.
Data Sensum built a custom Glide warehouse management app for Target Transport for approximately €3,000. The app gave warehouse operatives a barcode-scanning mobile interface for recording every stock movement. It gave supervisors a real-time inventory view. It gave clients a portal where they could see the current status of their goods without calling the office.
10x ROI within the first year. The app eliminated the manual reconciliation work that had been consuming hours every week, reduced stock discrepancies to near-zero, and removed a significant volume of inbound client status-chasing calls. At a total investment of approximately €3,000, against the operational savings in the first year alone, the return on investment was comfortably above 10x. That return was not possible at €90,000 or even €18,000 per year. It was only possible because the cost of deployment was proportionate to the size of the business.
Why Data Sensum Recommends Low-Code for SME Warehouse Operations
We are frequently asked whether a custom-built application or a well-known SaaS platform might be a better fit than Glide for a client's warehouse operation. Our honest answer is: almost never, for a logistics or transport SME.
Custom development is the right answer when your requirements are genuinely unique, your team has the technical capacity to maintain a bespoke codebase, and your budget supports a six-figure commitment. For most SMEs, none of those conditions are true.
SaaS is the right answer when your processes closely match the way the platform is designed to work, and you are comfortable permanently paying a per-user licence for software you will never own. In practice, that fit is rare. Most SMEs end up paying for features they do not need, missing features they do, and adapting their operations around the platform's limitations, the exact opposite of what a management system should do.
Low-code, specifically Glide for mobile-first warehouse applications, gives you something neither of the other options reliably delivers: a system built around your actual workflow, owned and controllable by your business, at a cost that makes commercial sense for a company of your size. When your business grows or changes, the app can be updated quickly and cheaply. When you want to integrate with a new system via API, it can be done without rewriting the application from scratch.
That combination, customisation, speed, low cost, and long-term flexibility, is why we recommend this approach to almost every logistics and transport SME we work with.
