Does CrewFlow replace a VMS?

No. If your client mandates a VMS, you continue to use it. CrewFlow is the supplier-side system that produces the data you submit.

Can CrewFlow send data to Fieldglass?

Data can be exported and pushed through the CrewFlow API and Integrations Hub. Direct connectors depend on the access your client's programme allows.

We are the client, not the supplier. Is CrewFlow relevant?

It can be, if you self-deliver labour. If you purely procure from third-party agencies, a VMS is the better fit.

How long does CrewFlow take to implement?

Self-service onboarding starts immediately; a guided enterprise rollout is typically measured in weeks.

Overview

CrewFlow and SAP Fieldglass at a glance

Fieldglass focuses on requisition, supplier competition, rate governance, statements of work and consolidated spend visibility for the client organisation.

CrewFlow focuses on what the supplier must do to deliver against that contract: recruit, evidence compliance, mobilise across borders, plan crews, capture time and invoice correctly.

Where a client mandates Fieldglass, CrewFlow is normally the supplier-side system feeding it — not a replacement for it.

Advantages

What SAP Fieldglass does well

Mature, enterprise-proven vendor management capability
Deep procurement and spend governance features
Strong fit for organisations already running SAP
Established supplier network and programme management practices

Limitations

Where teams typically hit the edge

Designed around the buyer's process, not the supplier's delivery operation
Posted-worker and A1 evidence workflows are typically handled outside it
Field-level crew planning and rotations are not its focus
Implementation is a programme, not a self-service signup

Typical use cases

Which to use, when

Use Fieldglass

You are the client organisation buying labour from many suppliers and need spend and rate governance.

Use CrewFlow

You are the supplier and need to mobilise, evidence and bill the crews you provide.

Use both

Deliver in CrewFlow, submit to the client's VMS; the API and Integrations Hub support that handover.

Pricing approach

How each is typically paid for

Pricing models change. Treat this as an indication of approach and confirm current commercial terms directly.

CrewFlow

Transparent per-seat subscription with worker-volume tiers, free trial and self-service start.

See CrewFlow pricing

SAP Fieldglass

Enterprise agreement, typically negotiated per programme and often funded through supplier fees.

Why CrewFlow

Why organisations choose CrewFlow

Built around the supplier's delivery workflow from won job to invoice
Posted-worker, A1 and Schengen tracking are first-class, not add-ons
Crew planning, rotations and availability are part of the core model
Workers get a native mobile portal for time, documents and expenses
Starts in days, not as a multi-quarter implementation programme
