Frequently Asked Questions

How do agencies bill monthly retainers?

Set up recurring invoices (Square, FreshBooks) with card on file for automatic payment. Invoice at beginning of month for retainer work. For overages, add to monthly invoice or bill separately.

What about billing for media spend?

Options vary: some agencies use agency cards and mark up spend, others bill pass-through with management fee. For large media buys, consider invoicing separately from services with shorter payment terms.
