POS operations guide
Auto repair workshop intake, estimate, parts, labour, safety-check, road-test, collection and client-balance POS workflow
A car workshop joins exact vehicle identity, intake condition, diagnostic evidence, repair-order approval, compatible parts and fluids, technician work, bay and lift controls, calibrations, safety checks, road-test authority, collection and account billing. Keep custody, technical evidence, stock movement, invoice and customer balance separate.
Evidence, safety and jurisdiction boundary
Evidence reviewed 2026-09-10. Reviewed the current Posnic release boundary and archived customer, sale and item models alongside US NHTSA VIN and recall resources, EPA used-oil and motor-vehicle air-conditioning guidance, and OSHA's automotive-service-lift interpretation. These sources illustrate identity, recall, environmental, refrigerant and workplace boundaries; they do not replace manufacturer repair information, competent technical judgment, or licensing, inspection, emissions, road-test, insurance, waste, warranty and consumer rules where a workshop operates.
This page does not establish a live auto-workshop deployment, correct diagnosis, compatible part, correct fluid, competent technician, safe lift, completed repair, valid calibration, authorized road test, passed inspection, roadworthiness, customer acceptance or payment settlement. Product evidence remains pinned to an archived source snapshot.
What the current product evidence establishes
Customer and balance fields exist
Customer identity, balance and payment terms can be inspected. They do not prove vehicle ownership, test-drive or collection authority, or privacy compliance.
Quote and sale records exist
Quotation and sale lines can model diagnostic labour, repairs, parts, fluids, subcontract work, deposits, credits and refunds. They do not prove authorization, workmanship or safety.
Item history can be evaluated
Item and stock-history paths can be tested for parts and consumables. They do not prove compatibility, installation, actual fluid use, core custody or waste handling.
Workshop work remains outside POS
Diagnosis, competency, lifting, manufacturer procedures, torque, alignment, programming, calibration, emissions work and roadworthiness require separate evidence and review.
Auto repair workshop POS controls before rollout
A repair order is not a diagnosis, a part sale is not a repair, and payment is not proof that a vehicle is safe to drive.
| Area | Record to keep | Why it matters | Acceptance check |
|---|---|---|---|
| Customer, vehicle and intake | Customer, payer, make, model, year, VIN, registration, odometer, fuel or charge, keys, documents, valuables, warning lights, visible condition, photos, complaint and custody. | Plate, payer, owner and collector may differ; fleet vehicles add authorization and purchase-order boundaries. | Every repair order, part, job, test drive and payment resolves to the intended vehicle. |
| Diagnosis and estimate | Symptoms, observations, scan report, measurements, fault codes, safety finding, uncertainty, labour, parts, fluids, subcontract, exclusions, version, limit and approving party. | A diagnostic trouble code is evidence, not by itself a diagnosis; scope and price can change after inspection. | Original findings, accepted estimate and later supplemental authorization remain visible. |
| Unsafe or do-not-drive state | Finding, customer notice, bay or parking location, key custody, release restriction, escalation and customer decision. | A repair-order or payment state must not erase a safety hold. | Unsafe vehicles cannot become ready through invoicing alone. |
| Parts, cores and fluids | Manufacturer, part number, VIN applicability, specification, batch or serial, quantity issued, installed, used, returned, core, removed part, waste route, supplier cost and customer charge. | Purchased or stocked material is not automatically compatible, installed or correctly used. | Selection evidence and every quantity or custody transition reconcile. |
| Technician, bay and lift | Assigned technician, competency scope, bay, lift identifier, pre-use condition, lifting points, support or restraint, work performed, procedure, tool and exception. | A staff role or POS status cannot prove competent work or safe lifting. | Work and lift evidence remain attributable and separate from billing. |
| Alignment, programming and calibration | Trigger, prerequisites, equipment and software identity, target specification, measurement before and after, result, exception and subcontract evidence. | Part replacement may require procedures beyond installation, including ADAS or electronic calibration. | POS never invents a successful alignment, programming or calibration result. |
| Safety check and road test | Brake, steering, wheel, tyre, suspension, restraint, light, leak and warning checks plus driver authority, licence, insurance, route, purpose, odometer, findings and incidents. | Completion or payment cannot authorize a driver or prove roadworthiness. | Failed, deferred and not-applicable checks remain explicit. |
| Refrigerant, emissions and waste | Technician credential, equipment, refrigerant identity and quantity, recovery or charge, used oil, coolant, battery, filter, tyre and waste-transfer evidence. | Stock adjustment is not certification, recovery, emissions or environmental evidence. | Material issued, used, recovered, returned and transferred reconciles under local rules. |
| Collection and owner close | Collector authority, vehicle, keys, documents, work, unresolved advice, invoice, deposit, tax, credit, payment, balance, custody, callbacks, open jobs, stock, waste and margin. | Ready, paid, safe and collected are different states. | Money, stock, vehicles and open obligations close together. |
Practical workflow
Identify at intake
Capture VIN, registration, odometer, fuel or charge, warnings, condition, keys, valuables, complaint and custody before quoting.
Diagnose and authorize
Preserve scan evidence, measurements, recall review, unsafe status, estimate version and supplemental approval.
Control work and material
Keep compatibility, stock issue, lift use, technician work, alignment, programming, calibration and safety evidence distinct.
Test, release and reconcile
Verify road-test authority, unresolved advice, collector, payment and custody transfer without merging their evidence.
Intake-to-collection flow
Intake and identify
Record customer, vehicle, VIN, odometer, condition, warnings, keys and complaint.
Diagnose and authorize
Preserve scans, measurements, recall review, unsafe status, estimate and approval.
Issue and repair
Link compatible material, technician work, bay or lift controls and actual quantities.
Check and invoice
Keep calibration, safety and road-test evidence separate while billing accepted work.
Collect and review
Verify handover, balance, stock, waste, deferred work and callbacks.
Hardware, software and data setup
Hardware
- Counter computer or tablet and estimate, repair-order or receipt printer.
- Camera for consented intake-condition and vehicle-identity evidence.
- Barcode scanner for parts, fluids, tyres, batches, serials and cores where supported.
- Separate suitable scan, lift, alignment, calibration, refrigerant and calibrated mechanical equipment; POS is not a diagnostic or safety-test instrument.
- Payment terminal without storing card data in POS.
- Off-device backup for customer, vehicle, repair-order, stock and payment references.
Software and data
- Minimum-necessary customer, payer, fleet, collector, vehicle and custody records.
- Separate diagnostic, labour, part, fluid, tyre, subcontract, deposit, credit and refund items.
- Distinct intake, diagnosed, awaiting-approval, awaiting-part, in-progress, unsafe-hold, checked, ready, collected and paid states.
- Restricted access to customer, registration, condition, scan, safety, road-test, collection and incident evidence.
- Reports for open repair orders, ready vehicles, holds, balances, cores, materials, callbacks, credits, waste and margin.
Setup sequence
- Write intake, identity, custody, diagnosis, repair-order, authorization, compatibility, bay, lift, technician, safety-check, road-test, collection, invoice, waste and callback rules.
- Create synthetic customers, vehicles, VINs, services, technicians, parts, tyres, fluids, cores, warranty providers and payment labels.
- Test condition, scan and measurement evidence, recall lookup and estimate revisions without overwriting intake or approval.
- Test unsafe holds independently of ready, invoice and payment states.
- Test compatibility, stock issue, actual use, unused return, core or removed-part custody and waste transfer.
- Test lift, technician, manufacturer-procedure, torque, alignment, programming and calibration evidence without inferring success from POS access.
- Test brake, steering, wheel, tyre, suspension, restraint, light, leak and warning exception workflows.
- Test road-test authority, collection identity, failed payment, credit, refund, warranty and callback scenarios.
- Reconcile invoices, receipts, balances, stock, cores, costs, custody, refrigerant, waste and open obligations.
- Back up and restore records, then obtain vehicle-safety, workplace, environmental, warranty, payment, privacy and local approval.
Product evidence to inspect

Evaluate payer references and balances while vehicle identity and technical evidence remain separate.

Sales can model accepted labour and material, not diagnosis, workmanship or safety evidence.

Test movement without treating it as compatibility, installation, actual use, recovery or waste evidence.

Sales reports support close while open repair orders, holds, custody and callbacks remain obligations.
Mistakes to avoid
- Treating a repair order, ready state, invoice or payment as proof of safe repair.
- Using only a plate or generic vehicle record without VIN, odometer, warnings and condition evidence.
- Installing parts or fluids without exact identity, specification and applicability review.
- Treating a fault code as a diagnosis or clearing codes without preserving evidence.
- Using a POS role as evidence of technician competence, lift safety, road-test authority or insurance.
- Marking alignment, programming or ADAS calibration passed because a related line was invoiced.
- Using stock adjustment as proof of refrigerant recovery, actual fluid use or lawful waste transfer.
- Releasing a vehicle without verifying collector, unresolved advice, keys, documents, payment and custody transfer.
