Picture a technician arriving where mobile reception is weak. Can they open the job details, record the work, and sync it later without creating duplicates? Requirements like these help you choose field-service software that works outside a sales demo.
Use this checklist to discover and prioritize requirements. Mark an item required only when you can name the user, event, information, rule, and consequence. A shorter verified list produces a safer first release than a long list copied from vendor pages.

SECTION 01
Map the field-service job lifecycle
Begin with the event that creates work: a customer request, planned maintenance schedule, alert, inspection cycle, contract commitment, or internal task. Follow it through triage, entitlement or eligibility, scheduling, assignment, travel, arrival, service, evidence, customer acceptance, parts reconciliation, billing handoff, and closure.
For every state change, name who can perform it, what information is required, what notification occurs, and what exception can block progress. The state model becomes the backbone of permissions, mobile screens, dashboards, integration events, and reports.
| Stage | Required decision | Evidence or output |
|---|---|---|
| Request | Is the customer, site, asset, issue, and entitlement known? | Validated request with urgency and source. |
| Plan | What skill, duration, parts, access, and timing does the work require? | Work order ready for scheduling. |
| Schedule | Which qualified resource and time window are feasible? | Assigned slot with conflict and travel checks. |
| Dispatch | Is the technician ready and is the latest job pack available? | Acknowledged assignment and route/status visibility. |
| Execute | What was inspected, done, measured, used, changed, or blocked? | Timestamped field record with required evidence. |
| Accept | Does the customer or supervisor need to review or sign? | Approval, exception, or follow-up requirement. |
| Close | Are parts, time, status, documents, and billing inputs complete? | Closed work order and downstream handoff. |
SECTION 02
Define users, roles, territories, and authority
List office users, dispatchers, technicians, subcontractors, supervisors, customer contacts, finance users, and system administrators. Separate what each role can see from what it can change. Customer contact details, service history, site access instructions, pricing, internal notes, and payment information may require different visibility.
Authority should cover assignment, rescheduling, cancellation, overtime, parts adjustment, warranty or entitlement override, customer sign-off, and work-order closure. Temporary cover, team changes, and lost devices should be part of the access design, not handled by shared accounts.
SECTION 03
Specify scheduling and dispatch rules
A scheduling requirement should state the constraints, not only request drag-and-drop. Consider skills, certifications where relevant, territory, working hours, leave, job duration, priority, service window, travel, dependencies, parts readiness, site access, and whether multiple people or visits are required.
Dispatch needs a reliable status model. Distinguish scheduled, acknowledged, traveling, arrived, in progress, paused, blocked, completed pending review, and closed only when those distinctions trigger useful actions. Avoid tracking precise worker location unless it has a clear operational need, disclosed policy, appropriate consent or legal basis, and controlled retention.
Planning view
Show demand, capacity, conflicts, unassigned work, service windows, and the information required to resolve them.
Change handling
Record who rescheduled, why, which customer/technician notices were sent, and what dependent work changed.
Technician acknowledgment
Confirm the assignment and surface missing access, parts, or skill information before travel.
Exception queue
Keep blocked, overdue, rejected, and incomplete work visible to an accountable office owner.
SECTION 04
Design the work order for mobile and offline use
The mobile experience should minimize searching and re-entry. A technician needs the current job, safe access information, customer/site/asset context, approved instructions, parts or tools, relevant history, a clear next action, and a way to record what happened. The interface should work on the actual devices, screen sizes, lighting, gloves or other input conditions involved.
Offline support is a data-consistency requirement, not a download button. Define which records are available offline, how long they remain, which changes can be made, how attachments queue, what happens when two people edit the same job, how conflicts are resolved, and how the user knows synchronization has succeeded.
SECTION 05
Define completion, evidence, and customer acceptance
Completion should be based on required evidence for the job type. That may include status, time, structured findings, measurements, parts used, work performed, photos, documents, exceptions, follow-up, and customer or supervisor acceptance. Do not collect every possible field for every job; conditional forms can keep the workflow useful while preserving necessary evidence.
Store the original submission and a history of corrections. If a customer signs, make the content being accepted clear and preserve the signed representation. A signature should not silently approve pricing, contractual terms, or claims beyond what is visibly presented.
SECTION 06
Connect parts, time, and payment or billing handoff
Decide whether the field system owns parts inventory or records consumption against an inventory/ERP source of truth. Cover vehicle stock, reservations, substitutions, returns, damaged parts, replenishment, serial or lot tracking when required, and reconciliation when mobile work is offline.
For billing, define which approved information moves downstream: labor type and duration, parts, travel, fixed service item, tax category, purchase order, customer approval, and exception. If payment is collected in the field, use an appropriate payment provider and avoid storing sensitive payment credentials in the field application.
| Domain | Likely source of truth | Field-service responsibility |
|---|---|---|
| Customer and opportunity | CRM | Read approved context and return service status or follow-up. |
| Asset and service history | Field system, ERP, or asset platform | Show current record and append controlled service evidence. |
| Inventory and purchasing | ERP or inventory system | Reserve, consume, return, transfer, and reconcile parts. |
| Accounting and invoicing | Accounting or ERP | Send approved billing inputs and retain downstream reference/status. |
| Identity | Organization identity provider | Authenticate users and apply role/territory access. |
| Customer communication | Approved communication service | Send event-based messages with preference and delivery status. |
SECTION 07
Plan security, reliability, reporting, and support
Protect access with individual identity, least privilege, secure session handling, encrypted transport and storage, managed secrets, device controls, and activity records appropriate to the risk. Limit offline data to what a technician needs and define removal or expiration for lost, replaced, or shared devices.
Operational monitoring should cover failed sync, stuck work orders, notification failures, integration errors, unusual access, and unresolved exceptions. Reports should answer decisions: demand versus capacity, first-visit completion definition, repeat visit reasons, overdue work, parts exceptions, data completeness, and customer follow-up. Define each metric so teams cannot interpret the same label differently.
- 01
Document threats, sensitive data, access boundaries, retention, and recovery expectations.
- 02
Test low connectivity, expired sessions, duplicate submissions, retries, and unavailable integrations.
- 03
Define backup, restoration, support ownership, incident escalation, and status communication.
- 04
Create operational dashboards for queues and failures before executive summary reports.
- 05
Review access, devices, integrations, metrics, and exception patterns after launch.
SECTION 08
Prioritize a complete first release
Group requirements into must operate, must control, should improve, and later. The first release should complete one real job type from request through closure and downstream handoff. It should include the support, monitoring, permissions, and recovery required to operate that slice safely.
A common deferral mistake is to postpone integration, offline handling, migration, or exception queues while building more visible screens. Those elements often determine whether the workflow can operate. Prioritize by operational dependency and consequence, not by visual appeal.
