Give the job a record that follows the work
Use the same job reference on purchase orders, timesheets, subcontractor bills and customer correspondence. Record parts by quantity and status: received, issued to the job, returned to stock, sent for warranty review or awaiting delivery. A supplier invoice for several jobs should be split using evidence rather than charged entirely to whichever customer is billed first.
Halifax Harbour and Dartmouth support marine service and ocean-technology activity, including the businesses around COVE. That context can involve prototype components, field testing and service visits as well as routine repairs. It does not give every marine sale the same GST/HST treatment. Confirm the customer, supply, delivery and any specific tax provision before applying a special code.
Illustrative example: an equipment service order
A Dartmouth service business has an approved $41,000 order, before sales tax. Its cost schedule records $12,600 of parts actually consumed, $8,400 of direct labour at the business’s documented costing rate, $3,200 of subcontract testing and $800 of job-specific freight. Those incurred direct costs total $25,000.
Another $2,600 of necessary direct work remains and is not included in those invoices or labour records. Forecast direct cost is therefore $27,600, leaving $13,400 of direct contribution. This is before overhead, financing and income tax. A proposed $2,250 customer change is still unsigned, so it is excluded from approved revenue until its status is resolved.
Separate purchasing commitments from consumption
A purchase order can create a cash commitment before the parts arrive. Receiving stock is different from consuming it on a job. Keep a commitment list alongside the cost report, but remove or update an item when its invoice enters incurred costs. Otherwise the same component can appear twice in the forecast.
Customer-owned equipment should also be identifiable without being treated as company inventory. Preserve delivery notes and ownership terms for items sent away for testing. If a supplier accepts a return, link the credit to the original cost and check whether it belongs to this job or to general stock. Do not recognize an expected warranty credit as settled money.
Close the job with a short handover
Before final billing, compare the approved scope with completion evidence and the open commitment list. Keep tax questions and unapproved variations visible so a margin report does not disguise unfinished decisions.
- Use one job reference from purchase to invoice.
- Record parts issued, returned and still held.
- Separate incurred costs from remaining commitments.
- Retain customer approvals and testing evidence.
