Accra agencies and studios bill foreign clients in dollars; Eversend lets you bank those invoices the same way. USD account details in your Ghanaian company's name, funded by your clients' ordinary ACH or wire, with cedis one on-screen rate away whenever you choose. Receiving costs 0.49% plus a fixed fee.
Retainers and project fees arrive as domestic US transfers, so no correspondent bank touches them in transit. The number on the invoice is the number in the account, less one visible fee.
