Send a Receipt, Not a Reminder
The first nudge should not feel like a nudge. Forward the original invoice with a short note: "Sharing this again in case it got buried." Attach a PDF, not a link. Many Indian finance teams work with printed records, and a link that requires a login will sit unopened. Keep the message under four lines. No apology for following up, no threat of consequences. A factual resend signals confidence without aggression, and it gives the client's accounts team something they can act on immediately without escalating internally.
