Shop Floor Control / Labor Tracking is where ERP discipline either begins or breaks.
Shop Floor Data Collection via Barcode / Terminal looks operational from far away. In a real finance team, it is a chain of assertions: the right actor started the work, the required records existed, the control policy was applied, the state change was preserved, and the outcome can be explained later without rebuilding the transaction from emails and spreadsheets.
The expected business outcome is specific: Labor accuracy improves from estimated to actual; job costing reflects real operator time; supervisors have live queue visibility enabling dynamic resource reallocation; payroll integration uses verified clock-in/out data.

Barcode (1D/2D) and RFID scan support; offline mode with sync on reconnect (≤ 5 minutes data loss tolerance); employee qualification check before clock-on; simultaneous multi-operation labor entry for setup/run overlap; downtime event recording with reason code; scrap entry with cause and disposition code; real-time WIP dashboard; integration with work center OEE metrics; transaction retry on connectivity loss; sub-second response on scan events; audit log of all scan transactions.
US and UK teams have different compliance hooks, but the same control problem.
US teams usually care about clean evidence for audit support, vendor records, payment controls, tax reporting, and management review. UK teams usually care about VAT-ready records, approval evidence, digital-record discipline, and traceable postings. The country-specific details differ, but the operating pattern is the same: the ERP needs controlled records, explicit ownership, defensible state changes, and evidence that survives beyond the person who completed the task.
The control matrix.
| Control area | Requirement | Acceptance proof |
|---|---|---|
| Control 1 | Barcode (1D/2D) and RFID scan support | Given a released work order operation and a qualified operator |
| Control 2 | offline mode with sync on reconnect (≤ 5 minutes data loss tolerance | when the operator clocks on via barcode scan |
| Control 3 | employee qualification check before clock-on | then a labor transaction is created with employee_id, operation_id, clock_on_at and operation status updates to IN_PROGRESS |
| Control 4 | simultaneous multi-operation labor entry for setup/run overlap | negative) when an operator scans on to an operation for which they lack the required skill certification then 403 OPERATOR_NOT_QUALIFIED. |
| Control 5 | downtime event recording with reason code | Labor accuracy improves from estimated to actual; job costing reflects real operator time; supervisors have live queue visibility enabling dynamic resource reallocation; payroll integration uses verified clock-in/out data. |
| Control 6 | scrap entry with cause and disposition code | Labor accuracy improves from estimated to actual; job costing reflects real operator time; supervisors have live queue visibility enabling dynamic resource reallocation; payroll integration uses verified clock-in/out data. |
Audit evidence is a chain, not a folder.
| Evidence layer | What should be preserved |
|---|---|
| Business event | An operator scans their employee badge and the work order barcode at a shop floor terminal or mobile device to clock on to a specific operation. The system validates the operation is in Released status and the operator is qualified (skill certification check). As work progresses, the operator scans intermediate checkpoints; the system records elapsed time automatically. At operation completion, the operator enters good quantity, scrap quantity, and scrap reason code, then scans off. The system posts the labor transaction, updates operation status, and triggers the next operation's queue. Supervisors monitor real-time WIP dashboards showing queue depth, in-progress jobs, and machine utilization. |
| Control rules | Barcode (1D/2D) and RFID scan support; offline mode with sync on reconnect (≤ 5 minutes data loss tolerance); employee qualification check before clock-on; simultaneous multi-operation labor entry for setup/run overlap; downtime event recording with reason code; scrap entry with cause and disposition code; real-time WIP dashboard; integration with work center OEE metrics; transaction retry on connectivity loss; sub-second response on scan events; audit log of all scan transactions. |
| Acceptance proof | Given a released work order operation and a qualified operator; when the operator clocks on via barcode scan; then a labor transaction is created with employee_id, operation_id, clock_on_at and operation status updates to IN_PROGRESS; (negative) when an operator scans on to an operation for which they lack the required skill certification then 403 OPERATOR_NOT_QUALIFIED. |

| Lifecycle state | |
The useful version of this workflow is not only fast. It is inspectable. A controller, auditor, or operator should be able to move from source event to system record to state transition to final business outcome without guessing.
Implementation contracts.
Reference data model
`labor_transactions` { txn_id: string, work_order_id: string, op_id: string, employee_id: string, clock_on_at: timestamp, clock_off_at: timestamp, good_qty: numeric, scrap_qty: numeric, scrap_reason_code: string, external_id: string }; `employee_qualifications` { qual_id: string, employee_id: string, operation_type: string, certified_at: date }; (reference, product may differ).API and events
`POST /v1/labor-transactions/clock-on` { employee_id, work_order_id, op_id, scan_timestamp } -> 201 { txn_id, status: CLOCKED_ON }; `POST /v1/labor-transactions/{txn_id}/clock-off` { good_qty, scrap_qty, scrap_reason_code } -> 200 { status: POSTED }; emits `labor.transaction_posted` event; idempotent via `external_id`.State transitions
`CLOCKED_ON -> CLOCKED_OFF -> POSTED`; terminal `REVERSED`; guard: qualification check at clock-on; duplicate clock-on without intervening clock-off returns 409 ALREADY_CLOCKED_ON.Common implementation traps.
Treating the workflow as data entry
If the ERP only stores the final record, the team loses the decision trail that explains how the record became valid.
Hiding exception logic
Exceptions need owners, reason codes, and time stamps. A vague pending state is not a control.
Posting without recovery design
Retries, duplicate submissions, and partial failures must be explicit so the system does not create inconsistent records.
Skipping evidence design
A workflow that cannot produce evidence on demand will eventually push finance teams back into manual screenshots and spreadsheets.
Where Rivane fits.
Rivane is built for finance workflows where automation must stay tied to source documents, approvals, state transitions, ledger impact, reporting, and audit evidence. Use this guide as a checklist for evaluating whether an ERP workflow is merely digitized or actually controlled.
References and source basis.
These sources provide the standards, regulatory, or government context around the flow. They are included so the guide is useful to finance operators, auditors, and implementation teams, not only buyers reading software copy.
