A business owner comes to us with a real problem: their field team is still filling in paper job sheets, photographing them, and emailing the photos back to the office. Someone then has to type the information into a spreadsheet. It's slow, error-prone, and everyone hates it.
The question is: what's the right solution? A low-code app built in a tool like Glide — up and running in days at low cost — or a properly engineered custom mobile application that will serve the business for years?
The honest answer is that both are the right answer, depending on the situation. Choosing wrong in either direction is an expensive mistake: building custom when you didn't need to wastes tens of thousands of euro and months of time; choosing low-code when you needed custom leaves you with a tool that breaks under real-world demands. Here's how to think through the decision.
What is Glide, and what makes it powerful?
Glide is a no-code platform that lets you build mobile and web applications directly from a data source — typically a Google Sheet, Excel file, or a simple database. You connect your data, configure screens through a visual drag-and-drop interface, set up forms and actions, and publish an app that works on any phone or tablet without needing to visit an app store.
The speed is the headline feature. A focused, well-scoped Glide app can be built and deployed in a matter of days. For an SME that needs a solution now — not in six months — that matters enormously. And because it's built on familiar tools like Google Sheets, your team can often maintain and update the underlying data without any developer involvement.
Glide is not alone in this space. AppSheet, Softr, Adalo, and Microsoft Power Apps operate on similar principles. But Glide is particularly well-suited to Irish SMEs because of its ease of use, clean mobile interface, and competitive pricing for small teams.
When Glide (or a low-code tool) is the right choice
Your process is well-defined and unlikely to change dramatically. Low-code tools shine when the workflow is clear and stable. A job completion form, a stock count tool, a daily inspection checklist, a customer visit log — these are well-understood processes with predictable inputs and outputs. Glide handles them excellently.
The user base is internal and modest in size. Glide apps work best for teams of up to a few dozen users. If you're building a tool for your own staff — field engineers, warehouse operatives, sales reps — rather than for thousands of external customers, a Glide app is perfectly capable.
You need to move fast. Low-code tools are ideal for proving a concept. If you're not sure whether a mobile tool will actually change behaviour in your team, a Glide prototype lets you test that hypothesis in days rather than months. Many businesses start with Glide, validate that mobile data capture solves their problem, and then decide whether the scale of use justifies a more engineered solution later.
Budget is constrained. A Glide app for a team of ten might cost €50–€200 per month in platform fees, plus a few days of build time. A custom mobile application — designed, built, tested, and deployed — will typically cost €20,000–€80,000 or more depending on complexity. For most SMEs, the economics of low-code are compelling when the use case fits.
Offline capability is not critical. Glide apps require an internet connection to function fully. If your team works in environments with reliable connectivity — urban sites, warehouses, offices — this is rarely an issue. If they work in remote locations with no signal, it becomes a significant constraint.
A good fit for Glide: A logistics company wants drivers to complete delivery confirmations and capture signatures on their phones. The workflow is consistent, the team is twenty people, connectivity is fine on urban routes, and they need it working within the month. Glide is the right answer.
When a custom mobile app is the right investment
You're building for external customers or a large public user base. The moment your app needs to be used by customers — people who didn't choose to work with your internal tools — the bar rises sharply. App store presence, polished UX, brand consistency, and performance under load all become non-negotiable. Low-code tools are not designed for this context. A customer-facing app requires custom development.
You need deep integration with hardware or device features. Bluetooth scanners, NFC readers, barcode cameras, GPS tracking with background operation, biometric authentication — these hardware integrations require native or near-native development. Glide and similar tools expose only limited device functionality. If your use case depends on device hardware beyond basic camera and location access, you need custom code.
You have complex, multi-layered business logic. Low-code tools handle conditional logic, but they have a ceiling. If your app needs to enforce complex pricing rules, manage multi-party workflows with approvals and escalations, integrate with multiple back-end systems in real time, or process significant volumes of transactional data, you will eventually hit the limits of what a no-code platform can reliably do.
Offline-first operation is essential. If your team works in basements, rural areas, warehouses with poor signal, or environments where internet connectivity cannot be guaranteed, a proper offline-capable mobile app — one that stores data locally and syncs when a connection is available — requires custom development. This is a genuinely hard engineering problem that low-code platforms do not solve well.
You need to own the platform completely. When you build on a third-party no-code platform, you are dependent on that platform's continued existence, pricing decisions, and feature roadmap. For a business tool that is genuinely mission-critical — one that the business cannot operate without — the dependency risk of a third-party platform deserves serious consideration. A custom-built application is an asset you own outright.
Scale and performance matter. Low-code tools can struggle under significant concurrent load or with large datasets. If your app will be used by hundreds of people simultaneously, or needs to handle thousands of records in real time, performance testing and architecture decisions that simply aren't possible in a no-code environment become important.
A good fit for custom: A facilities management company wants a customer-facing app where clients log maintenance requests, track job progress, and sign off on completed work — with full offline capability for engineers working in basement plant rooms. This warrants custom development.
The middle ground: low-code as a stepping stone
One of the smartest approaches we see is using a Glide app to validate a concept before committing to custom development. Build the workflow in Glide, get it into the hands of your team, learn what works and what doesn't, and gather real usage data. Then, if the tool proves its value and you're hitting the limits of what Glide can do, commission a custom build with a clear specification derived from real experience rather than assumptions.
This approach de-risks the custom investment significantly. You're not writing a six-figure cheque based on a requirements document — you're building on validated learning. The Glide version might serve you for a year or two before the business grows to the point where custom development makes economic sense.
A practical decision framework
Before committing to either path, answer these questions honestly:
Who are the users? Internal team only → Glide may well suffice. External customers or public users → custom is almost certainly necessary.
Is offline operation required? No → Glide is viable. Yes → custom development is required.
What's the timeline? Need it within weeks → Glide. Can invest 3–6 months in proper development → custom is on the table.
What's the budget? Under €10,000 → custom is not realistic; low-code is the right choice. Over €30,000 available and the tool is genuinely mission-critical → custom deserves serious consideration.
How complex is the logic? Straightforward forms, lists, and status updates → Glide. Multi-system integrations, complex rules, hardware dependencies → custom.
How important is it to own the platform? Tool is nice-to-have efficiency gain → dependency on a third-party platform is acceptable. Tool is mission-critical and irreplaceable → consider the risk of platform dependency carefully.
What we typically recommend
For the vast majority of Irish SMEs we work with, a Glide app is the right answer — at least to start. The speed, cost, and flexibility advantages are substantial, and most internal business processes fit comfortably within what the platform can deliver. The scenarios where custom development is clearly warranted — customer-facing apps, offline-first requirements, large user bases, complex hardware integrations — are real but less common than the vendor pitch for custom development might suggest.
The key is to be honest about which category your situation actually falls into, rather than letting budget constraints push you toward low-code when you genuinely need custom, or letting vendor enthusiasm push you toward expensive custom development when Glide would do the job perfectly well.
