Build a complete billing package
The job record links the work date, location, purchase order, crew time and customer sign-off. A missing approval can delay cash even when the work is finished. We separate completed but unbilled work from submitted invoices, disputed charges and amounts approved for payment.
Parts and subcontractor invoices are matched to the same reference. That helps distinguish a genuinely profitable job from one whose costs have not arrived. Equipment repairs, travel and standby costs also remain visible instead of disappearing into one general field-expense category.
Classify the work before selecting PST
Oilfield service is not one universal PST category. Saskatchewan’s petroleum bulletins distinguish taxable, exempt and non-taxable activities. We preserve the contract description and itemized charges needed to assess the actual work, and flag a change in scope that may change the treatment.
Illustrative regional service example
A Regina-based crew submits $38,000 of work for sites in southern Saskatchewan. Tickets supporting $6,400 are still missing customer sign-off, while $4,800 of parts invoices have not yet reached the office. The weekly review shows the billing obstacle and incomplete cost picture separately. Completing the ticket package improves the collection process; it does not remove the need to capture the missing purchase costs.
Questions about this work
Do you imply that extraction takes place in Regina?
No. The service supports businesses based in or coordinated through Regina whose field operations and customers may be in rural Saskatchewan.
Can every field invoice use the same PST code?
No. The work, contract and separately stated charges need review against the relevant Saskatchewan guidance.
