Trades Workflows: Connect the Site and the Office
Plan accepted scope, variation approval, field evidence and billing handoff, including interrupted connections.
The practical answer
Start with the handoff between accepted scope, work on site and reviewed billing. Keep proposed variations separate from approvals and test what happens when connectivity fails.
Discuss your business technology requirements, users and existing tools so we can define a useful website or web app scope. Discuss your website or app.
For a trade or construction business, the useful software question is often how to connect an approved quote with the work actually done on site and the invoice prepared in the office. Start with the tools you already use. Add a focused workflow only where a repeated handoff remains unreliable.
Example: protect the quote-to-job handoff #
This is a fictional design example. It does not claim a measured client result or replace the business’s contractual, safety or professional decisions.
- 1. Confirm the accepted scopeResponsible: Office or estimatorCreate a job from the accepted quote version. Attach the relevant plans or instructions and identify the job owner.
- 2. Make the job usable on siteResponsible: Job supervisorShow the current scope, assigned tasks and approved contacts on a phone. Make document versions clear.
- 3. Raise a proposed variationResponsible: Field staff and authorised approverRecord the changed work and supporting evidence. Keep proposed, approved and completed states separate; taking a photo does not approve a variation.
- 4. Record completionResponsible: Job ownerConfirm agreed checks and attach relevant evidence. Unresolved defects or questions remain assigned rather than disappearing into a note.
- 5. Prepare billingResponsible: Office reviewerReconcile the accepted scope, approved variations and completion record before handing off to the accounting system.
Design for unreliable connectivity #
Decide what must work without reception. Offline capability is a specific requirement, not an automatic property of a web app. If supported, show which changes are pending, how conflicts are resolved and when an upload has actually arrived. If it is not supported, give staff a clear fallback rather than silently losing a submission.
| Scenario | Expected behaviour |
|---|---|
| Photo upload is interrupted | A visible retry state; no false completion message |
| Two people change a task | A defined conflict rule and visible current status |
| Scope changes while staff are on site | Current version is identifiable; outdated instructions are not presented as approved |
| The same billing handoff is retried | One reviewed result, without duplicate invoices |
| A subcontractor finishes their assignment | Access is removed under the agreed process |
Keep safety decisions with the responsible people #
A system can record checks, route issues and preserve evidence. It does not establish that work is safe or replace competent supervision. Use WorkSafe’s risk-management guidance when the scope touches safety processes, and have the business define the actual controls and escalation.
Prove one improvement before expanding #
Trial one crew or job type. Measure missing completion information, unapproved variations discovered at billing, time spent chasing photos and work lost through failed submissions. Include the effort to review what staff capture. Compare the existing job-management product’s configuration before building a parallel job database.
A first release might only improve variation approval and completion handoff. Stock, scheduling, payroll and a full customer portal can remain separate decisions. The process-mapping tutorial helps define those boundaries.
