For bookkeeping, the distinction that actually matters is not the address vs the invoice. Every Lightning payment settles against a single-use BOLT11 either way. What matters is where you record the context:
BOLT11 you issue directly: you choose the memo / fiat rate / client id at creation time, so reconciliation is payment_hash -> your invoice record. Easiest audit trail.
Lightning Address (LNURL-pay): the payer's wallet asks your server for an invoice. The invoice commits to sha256(metadata) (the description_hash), not a readable memo, so the invoice itself tells your books nothing. Log it server-side: at callback time, store payment_hash, amount, comment (LUD-12), payer name (LUD-18) / zap request (NIP-57), fiat rate keyed by payment hash. Then it's exactly as reconcilable as a BOLT11.
Rate-lock tip: for fiat-denominated clients, give each client their own address path (client-acme@you), or require a LUD-12 comment with the invoice number. That way the callback log ties the payment to the bill.
So for recurring freelance payouts: an address for convenience, plus a callback log keyed on payment_hash, gives you both.
