POS operations guide
Electrical service contractor fault-finding, call-out, estimate, certificate, material-cost and client-balance POS workflow
Electrical service joins urgent call-outs, circuit-specific fault finding, estimate approval, licensed work, isolation, installation, testing, certificates, callbacks and account billing. Keep attendance, technical evidence, certificate status, stock movement, invoice and client balance separate.
Evidence and jurisdiction boundary
Evidence reviewed 2026-09-10. Reviewed the current Posnic release boundary and archived customer, sale and item models alongside current OSHA electrical-contractor, construction wiring-protection and circuit lockout/tagging sources. These US sources illustrate hazard, protection and isolation boundaries; they do not replace manufacturer instructions or licensing, electrical-code, inspection, testing, certification, notification, worker-safety and consumer rules where a contractor operates.
Stable release: v1.6.1. This page does not establish a live electrical deployment, correct fault finding, valid licence, accepted work, suitable material, safe isolation, passed tests, valid certificate, required notification, safe restoration, client sign-off or payment settlement. Product evidence remains pinned to an archived source snapshot.
What the current product evidence establishes
Client and balance fields exist
Customer identity, balance and payment-term fields can be inspected for a client or payer. They do not prove property authority, circuit identity, work authority or privacy compliance.
Quote and sale records exist
Quotation and sale lines can model call-outs, labour, cable, devices, credits and refunds. They do not prove fault findings, work, tests, certificates or safety.
Item history can be evaluated
Item and stock-history paths can be tested for cable, protection devices, enclosures, accessories and consumables. They do not prove design selection, rating, installation, test results or certification.
Technical work remains outside POS
Fault finding, licence scope, energized-work decisions, isolation, installation, inspection, testing, certification, notification and restoration require qualified review.
Electrical service contractor POS controls before rollout
A booked call-out is not fault finding, an invoice is not a test certificate, and payment is not proof that an electrical system is safe or restored.
| Area | Record to keep | Why it matters | Acceptance check |
|---|---|---|---|
| Client, site, payer and circuit | Contracting party, service site, billing entity, board, circuit, equipment and work-point identifiers, access, property authority and privacy boundary. | Owner, occupant, manager and payer may differ; one site may contain many supplies and circuits. | Every call-out, job and charge resolve to the right client and electrical work point. |
| Intake and fault finding | Reported outage, tripping, heat, smell, sparking, damage or shock; energized state, prior work, observations, readings, test point, method, instrument, electrician, time and uncertainty. | A customer description or protective-device trip alone is not a diagnosis. | Urgency, original readings and revised findings remain attributable. |
| Call-out, estimate and authority | Attendance fee, included time, travel, after-hours terms, fault finding, labour, materials, equipment hire, subcontract, disposal, exclusions, tax, price, validity, approval limit and version. | Attendance may be chargeable while repair scope changes after fault finding or access. | Accepted call-out terms, estimate version and approving party remain identifiable. |
| Licence and work gate | Electrician licence, registration or endorsement, jurisdiction, work category, evidence, expiry and required supervision. | A staff assignment or POS role does not establish authority for electrical work. | Missing, expired or out-of-scope evidence blocks ready status. |
| Energized state and isolation | Energized-work decision, justification, authority, source, isolation point, lock and tag identity, verification, electrician, time and restoration authority. | Urgency, assignment or sale status cannot establish safe isolation or authorize energized work. | Isolation and restoration evidence remains separate from billing. |
| Work and test evidence | Arrival, circuit, fault reference, isolation, work performed, conductor or device installed, removed item, test method, instrument, readings, limits, electrician, time and completion. | A generic sale line cannot prove correct installation, passed tests or safe restoration. | Operational evidence is linked without being invented by POS. |
| Material suitability | Manufacturer item, cable or conductor type, device function, voltage and current rating, breaking capacity where relevant, batch or serial, installed location and acceptance. | Purchased, stocked or invoiced material is not automatically suitable for the circuit or environment. | Design and selection evidence remain reviewable separately from billing. |
| Certificate and hand-off | Certificate type, jurisdiction, work scope, test references, defects, issuer, recipient, issue date, authority notification and restored or isolated state. | Certificate and notification duties depend on work and jurisdiction. | Invoice status cannot create a certificate or override an unsafe, untested or incomplete state. |
| Material movement | Stock issue, item and batch, quantity out, actual use, unused return, removed material, retention, recycling, disposal, adjustment and owner. | Stock movement is not correct selection, installation or waste-handling evidence. | Installed, returned and removed quantities reconcile with a reason and owner. |
| Cost and client charge | Estimated and actual call-out, labour, material, freight, equipment-hire, subcontract and disposal cost plus accepted client price. | Attendance, internal cost, landed cost and sale price affect margin differently. | Cost changes do not overwrite client approval. |
| Callback or repeat fault | Complaint, new diagnostic evidence, cause review, warranty boundary, revisit, extra work, credit and resolution. | A repeat fault is not silently a completed new sale. | Original service and every decision stay visible. |
| Invoice and collection | Invoice period, evidenced attendance and work, accepted call-out, labour and material charges, tax, credit, due date, payment and reversal. | Revenue and remaining repair or maintenance obligations can diverge. | Client balance reconciles to accepted terms and evidenced work. |
| Owner close | Open call-outs, faults, estimates, jobs, isolations, tests, certificates, notifications, defects, material movement, callbacks, receivables, credits, incidents and margin. | Cash close alone hides electrical and certification obligations. | Finance, stock and electrical-service obligations close together. |
Practical workflow
Accept call-out terms first
Record urgency, electrical state, access, attendance fee, included time and after-hours terms before dispatch.
Preserve fault findings
Keep test points, readings, instruments, uncertainty, alternatives, materials, exclusions and accepted estimate version visible.
Link isolation, work and tests
Keep energized-work decisions, locks and tags, installation, readings, defects and restoration evidence outside the invoice.
Issue certificates separately
Connect certificate and notification references to the work without treating a receipt or payment as technical evidence.
Call-out-to-payment flow
Intake and dispatch
Capture client, site, urgency, system, access and accepted call-out terms.
Diagnose and authorize
Record findings, version work and materials, and retain approval.
Work and test
Keep isolation, material, installation, removed-item, test and hand-off evidence outside the invoice.
Invoice evidenced work
Reconcile attendance, labour, materials, credits, tax and approval.
Collect and review
Close payment, client balance, callbacks, stock, cost and open service obligations.
Hardware, software and data setup
Hardware
- Office computer or tablet and quote or receipt printer.
- Field device only after offline, access-control and privacy testing.
- Separate appropriate voltage, continuity, insulation, grounding and protection-test instruments; POS is not a test instrument.
- Barcode scanner where cable, conductor, breaker, fuse, enclosure, accessory, batch or serial workflows support it.
- Payment terminal without storing card data in POS.
- Off-device backup for client, circuit, work, test, certificate, stock and payment references.
Software and data
- Client, payer, site, board, circuit and equipment accounts using minimum necessary data.
- Separate call-out, fault-finding, labour, material, certificate, callback, credit and refund items.
- Distinct requested, dispatched, attended, assessed, authorized, isolated, worked, tested, certified, restored, invoiced and paid states.
- Restricted access to licences, access details, hazards, findings, tests, certificates and incident references.
- Reports for balances, open work, defects, certificates, material movement, callbacks, credits and margin.
Setup sequence
- Write intake, urgency, call-out, fault-finding, estimate, licence, energized-work, isolation, work, test, certificate, restoration, callback, invoicing and credit rules.
- Create synthetic clients, sites, payers, boards, circuits, equipment, services, electricians, cable, protective devices, accessories and payment labels.
- Accept call-out terms, then version one fault finding and estimate without merging attendance into repair approval.
- Test licence-scope, energized-work decision, isolation, lock, tag and restoration gates.
- Test material issue, rating evidence, installation, unused return, removal and disposal references.
- Test instrument identity, readings, expected limits, exceptions and corrective-action references.
- Test certificate issue, recipient, work-and-test linkage and required notification separately from invoicing.
- Test unsafe defect, incomplete work, unavailable material, repeat fault, failed payment and credit.
- Reconcile invoices, receipts, stock movement, actual costs, callbacks and open technical obligations.
- Back up and restore records, then obtain operations, licensing, electrical-safety, payment, privacy and local approval.
Product evidence to inspect
Mistakes to avoid
- Treating booking, dispatch, attendance, invoice or payment as proof of fault finding or safe work.
- Hiding call-out, after-hours or diagnostic-credit terms until invoicing.
- Using one client-level note for multiple boards and circuits without a precise work point.
- Storing conductors and protection devices as generic materials without rating and item evidence.
- Using POS permissions as evidence of an electrician licence, isolation, qualification or work scope.
- Generating a certificate from invoice status without the required work and test evidence.
- Overwriting fault, estimate, isolation, work, test, defect, certificate or callback history.
- Putting access codes, hazard details or sensitive site information on receipts.
