Invoicing software for marketing agencies earns its keep on the first of the month. Most of an agency's revenue is recurring, so a good setup bills every retainer from an authorized card or bank account and leaves account managers free to manage accounts. A three-person shop with fifteen clients should not need a billing afternoon every month.
If you are working out how to get paid as a social media manager, start with terms: a signed social media manager contract that lists deliverables, a deposit or first month in advance, and a clear rate for extras. That makes scope creep a billing question instead of an argument.
Ad spend is the other cash-flow trap. Bill it separately from your fee, ideally before the campaign runs, so client budgets never sit on your agency card. KadePay keeps the retainer, the ad spend invoice and any add-ons on the same client profile, so a quarterly review with the client starts from one clear payment history.
KadePay does not schedule posts, report on campaigns or manage tasks. It is the billing, onboarding and payment side of the agency, and you can download transactions for your bookkeeper whenever they ask.
