Build the billing evidence into the routine
Purchase-order references, signed stages and client instructions should be retained with the engagement. A rejected invoice needs a reason and next action rather than a new expected-payment date every month. Advances remain linked to their contractual purpose.
Recoverable travel and subcontractor costs need the customer’s agreed terms. An expense incurred by the firm does not automatically create a collectible recharge.
Review shared operating commitments
Staff, subscriptions and premises costs can span several engagements. A supportable allocation can help management compare work types while leaving the accounting policy clear. Purchases affected by the October 2026 professional-services PST change require their own dated review.
Illustrative example: two engagements share a specialist
A Burnaby advisory firm hires a specialist for two clients. The invoice identifies $3,600 for one engagement and $2,400 for the other. Matching those references to the approved scope explains the direct costs and which customer recharge, if any, is permitted under each contract.
Questions about this work
Can you track retainers?
Yes, with the agreement and service period supporting the schedule. Their accounting treatment is reviewed separately from receipt of cash.
Does general bookkeeping include regulated client-money reporting?
No. Any trust-account or professional regulatory requirement needs a separately confirmed scope and applicable expertise.
