A field service app is a mobile app for site, inspection and field staff that moves dispatch, checklists, photos, sign-off and reporting from paper, Excel and chat apps into one system, so managers can see the progress and records of every job in an admin back office. Off-the-shelf SaaS construction management software is quick to adopt and billed monthly, but your form fields, workflow and permissions must fit the product's design, and ERP integration is limited. A custom field app is designed around how your staff actually work: checklists, approval steps and reports follow your company's rules, it connects to your existing ERP and admin, and the data stays on your own servers or cloud. When the workflow is simple and standard, start with off-the-shelf software; when it is specific to your company, must connect to your ERP, or the packaged tool no longer fits, consider a custom app.
Real projects Construction, inspection and field work
Below are the construction management apps, inspection and maintenance apps, and frontline staff apps we have developed.
Since 2025Engineering company

2026Engineering contractor
A second round of feature extensions on a construction management app already in use.
2022Car rental company
An app for managing inspection work, bringing inspections from the field into one system.
Landscape engineering firm
Daily maintenance, inspection and management of street trees used to run on Excel across large volumes of plant and works data. After in-depth interviews on the inspection and maintenance workflow, we built an online management system.
2023Fubon Life
An education and training app used by frontline sales staff.
2025Internet service provider
A maintenance work app used by maintenance staff.

Use cases What a field service app usually covers
Daily work that now runs on paper, Excel or photos sent to chat groups is the best place to start.
Managers assign work orders, staff and time slots in the admin; field staff accept jobs in the app and status returns in real time.
Checklists by equipment or work item, photos tagged with location and time, and follow-up tasks opened directly from failed items.
In basements, mountains or sites with poor signal, fill in forms and take photos on the phone, then sync when back online.
Completion reports, on-site signatures and manager approval in the app, with approval steps set by your company's rules.
Equipment, sites, locations and full history in one place; scan a QR code on site to see past inspections and repairs.
Work orders, hours, parts and reports connect to your existing ERP or admin through APIs, with no extra copy of the data.
Compare Off-the-shelf software vs custom app vs paper and Excel
Each fits a different stage. Many teams get by on Excel and chat groups, try packaged software, and decide on a custom app once the workflow is settled.
| Aspect | Off-the-shelf SaaS software | Custom field app | Paper / Excel + chat apps |
|---|---|---|---|
| Getting started | Off-the-shelf SaaS software: Sign up, configure and use | Custom field app: Interviews, design and build, then a phased rollout | Paper / Excel + chat apps: Ready now, nothing to adopt |
| Forms and workflow | Off-the-shelf SaaS software: Fit the product's fields and flow | Custom field app: Designed around your checklists, approval steps and permissions | Paper / Excel + chat apps: Filled in individually, formats drift |
| Sites without signal | Off-the-shelf SaaS software: Depends on each product's offline support | Custom field app: Offline entry and sync designed to your needs | Paper / Excel + chat apps: Paper works, but must be re-entered later |
| Photos and records | Off-the-shelf SaaS software: Stored in the product, searchable by its features | Custom field app: Photos tied to the job, location and time, searchable in the admin | Paper / Excel + chat apps: Scattered across chat groups and personal phones |
| ERP and existing systems | Off-the-shelf SaaS software: Limited to the product's integrations | Custom field app: Connected to your ERP and admin through APIs | Paper / Excel + chat apps: Compiled and re-keyed by hand |
| Where data lives | Off-the-shelf SaaS software: The vendor's cloud | Custom field app: Your own servers or cloud | Paper / Excel + chat apps: Paper, files and personal phones |
| Cost structure | Off-the-shelf SaaS software: Monthly fees by user or feature | Custom field app: One-time build, separate maintenance after launch | Paper / Excel + chat apps: Low tool cost, high manual effort |
Process How we build it
Whether a field app works depends on whether it matches how people really work. We interview and ride along first, then roll out in phases, with something you can accept at the end of each one.
2–4 weeks
Interview managers and frontline staff, follow them on site or along an inspection route, review current paper forms, Excel files and reporting, and decide which workflow comes first.
Depends on scope
Checklists, dispatch and approvals become a clickable prototype that field staff try on their phones, checked for outdoor use and gloved hands before sign-off.
6 weeks–6 months
App, admin and APIs are built together. One team or route pilots it first, and we adjust based on feedback before rolling out company-wide.
Ongoing
Monitor sync, upload and account errors, and adjust for mobile OS updates and workflow changes. The same team stays responsible.
Pricing Price ranges
Estimates based on custom app and system projects in Taiwan in 2026. The final figure depends on the number of workflows, user roles, offline needs and the systems to connect.
| Scope | Price range | Typical content | Timeline |
|---|---|---|---|
| Requirements and site interviews | NT$100k–300k | Interviews and ride-alongs, review of forms and workflows, producing a comparable spec | 2–4 weeks |
| Single-workflow app | NT$500k–1.2M | Either inspection or dispatch, plus an admin back office | 6–12 weeks |
| Full-featured | NT$1.2M–3M | Dispatch, inspection, sign-off, offline, reports and multi-role permissions | 3–6 months |
| Connect existing systems | NT$50k–200k per integration point | ERP, HR, maps or equipment data | Depends on the other system's API |
Mobile devices, app store account fees and cloud hosting are billed by actual usage. Post-launch maintenance is a separate agreement.
FAQ Common questions
Based on custom projects in Taiwan in 2026: either inspection or dispatch with an admin back office is about NT$500k–1.2M; dispatch, inspection, sign-off, offline, reports and multi-role permissions is about NT$1.2M–3M; each existing system connected (ERP, HR, maps or equipment data) is about NT$50k–200k. Requirements and site interviews before development are about NT$100k–300k.
A single workflow, either inspection or dispatch with an admin, takes about 6–12 weeks; a full-featured app with dispatch, inspection, sign-off, offline and reports takes about 3–6 months. Site interviews and requirements take another 2–4 weeks beforehand, and rollout usually starts with one team.
If your workflow is simple and close to the product's defaults, start with SaaS software: it is quick to adopt and billed monthly. A custom app fits better when your forms and approvals are company-specific, you need offline work, it must connect to your ERP, or the data must stay with you. You can also run packaged software for a while and build custom once the workflow is settled.
Yes. An offline-capable app lets staff fill in checklists, take photos and collect signatures without signal; the data is stored on the phone and synced to the admin when back online. Which features work offline and how sync is handled are confirmed during site interviews, based on the real working conditions.
Yes. Work orders, hours, parts and reports are exchanged with your ERP or admin through APIs. Without an API, file exchange or an intermediary database can work, but reliability and maintenance cost are assessed first. Each integration point is about NT$50k–200k, depending on the other system's API.
Design around how staff already work instead of asking them to adapt to the system. We interview and ride along first, move paper forms onto the phone largely as they are, and size buttons and text for outdoor use and gloved hands. Rollout starts with one pilot team, changes are made from their feedback before expanding, and paper and app can run side by side during the transition.
