Flux lets copywriting agencies take cards for convenience, ACH for larger invoices where the economics are friendlier, and pass the processing fee to the client at checkout where local rules allow.
Why copywriting agencies choose Flux
ACH for large invoices
Route retainers and big invoices over ACH where the per-transaction economics beat cards.
Pass the fee where allowed
On consumer pass-through, the processing fee is added to the client's total at checkout, where local surcharging rules allow.
Books that reconcile
A QuickBooks sync keeps copywriting agencies from retyping every payment into the accounting system at month end.
How copywriting agencies get paid
For copywriting agencies, ACH usually fits large invoices and retainers, cards suit smaller or on-the-spot payments, and Flux handles both through one integration with a clean record for your books.
A typical Flux setup for copywriting agencies
Copy billing splits between projects and retainers. Projects, a website rewrite, a launch sequence, a messaging guide, collect half up front by card at signing and the balance at delivery of final copy. Content retainers, a set volume of deliverables per month, run as recurring card charges at the start of each service month. Tickets are moderate, clients are remote, and nearly everything is card-not-present with settlement in 1-2 business days.
Agencies subcontracting to larger agencies, a meaningful slice of this market, invoice monthly on ACH with net terms, settling in 1-3 business days. New direct clients pay the deposit before kickoff, full stop, since words are the easiest deliverable to take and never pay for. The REST API can generate deposit links straight from an accepted proposal, and QuickBooks sync keeps retainer revenue and project revenue cleanly separated.
What copywriting agencies should watch
Revision disputes are the industry's chronic friction: copy is subjective, and a claim that the voice is wrong can arrive at round four. The payment structure is the containment: the deposit covers discovery and first draft, included rounds are counted in the agreement, and the balance is due at the contractual definition of delivery, not at the client's feeling of doneness. Additional rounds get their own line items and their own payment links.
Kill fees deserve explicit terms, because projects die mid-draft when strategies shift. Define the fee by stage reached, invoice it immediately on cancellation, and treat the deposit as its floor. On retainers, watch rollover creep: unused deliverables that accumulate as informal credit become a dispute when the client cancels and wants them refunded, so state plainly whether capacity rolls over, for how long, and what happens to it at termination.

How fast do copywriting agencies get their money?
Card payments settle in one to two business days and ACH in one to three business days. Stablecoin payments go to your wallet instantly.
Should we ever start work before the deposit is paid?
No. The deposit link goes out with the signed agreement and work begins when it is paid; card authorization is immediate and settlement follows in 1-2 business days. This is the single most protective habit in the business.
How do we charge for revision rounds beyond scope?
As separate line items with their own payment links, quoted before the round begins. Counting included rounds in the agreement is what turns the extra-round conversation into a process instead of a confrontation.
What happens to unused retainer capacity when a client cancels?
Whatever your agreement says, which is why it must say something: define whether deliverables roll over, for how long, and that unused capacity is not refundable after the notice period. Ambiguity here is where retainer disputes are born.
