Okappy vs BigChange for drainage contractors
BigChange is a well-known field service platform. Okappy is different because it is built around a connected network model, which matters when drainage jobs involve office teams, engineers, customers and subcontractors.
The practical buying question
For drainage contractors, the decision is not simply which system has the longest feature list. The real question is which system helps you manage live work across multiple parties with less chasing and clearer evidence.
Emergency work
How quickly can the office assign a callout and see live progress?
Subcontractors
Can external suppliers update the job without work disappearing into email or WhatsApp?
Customer visibility
Can clients get clearer answers without the office rebuilding the job story manually?
Positioning comparison
| Area | Okappy | BigChange-style systems |
|---|---|---|
| Core job management | Manage jobs, engineers, updates, evidence and invoices. | Typically strong at scheduling, job sheets and workforce management. |
| Subcontractor collaboration | Designed around connected multi-company working. | Often more focused on managing your own fleet or workforce. |
| Customer collaboration | Supports shared visibility around live work and job progress. | May require more internal admin to keep customers updated. |
| Best fit | Drainage and field service teams that rely on customers, employees and subcontractors working together. | Teams prioritising broader fleet, workforce or operational management suites. |
