Frequently asked questions

How should I bill ad spend?

Itemise it as a reimbursement at cost — never mark it up unless you have an explicit "media buying" arrangement. Most clients prefer to fund ads directly.

Should marketing consultants charge GST?

If annual income exceeds $75,000 — yes. Most established consultants are GST-registered.

How do I bill a retainer?

Fixed monthly fee invoiced on the 1st (in advance). Define deliverables in the engagement letter so scope creep doesn't happen.

What payment terms work?

Net 14 for SMB, Net 30 for corporate. Retainers should be paid upfront before the month starts.
