Accounting teams email support every month asking for invoices that already exist in the system. They have the order number, sometimes not. They need a clean PDF with the company VAT ID, sometimes a corrected billing address. Each request goes to a human who clicks through to the order, regenerates the PDF in the invoicing plugin, and emails it. The work is mechanical but it still takes five minutes per ticket, and a busy B2B store can see 50 of these a month.

SleekAI handles invoice lookup as a direct query on wp_wc_orders, wp_edd_customers, or whichever custom orders table your business uses. The customer pastes an order number, gives a date range, or names the amount. The bot finds the match, confirms the buyer identity by checking the logged-in user or asking for the email on file, then calls your invoicing plugin (PDF Invoices and Packing Slips, YITH Invoice, WP Invoice) to generate and email the PDF. The whole thing takes 30 seconds.

The edge cases need real attention. Billing address corrections require validation. Multiple-order date ranges need a numbered list. VAT ID changes might trigger a credit note plus reissue depending on jurisdiction. The bot handles the routine resends fully, prompts the customer through corrections, and escalates anything tax-sensitive to a human. Generic chatbots cannot read order tables or call invoice plugins, so they collect the request and forward to email anyway, defeating the point.

Invoice resend tickets are pure routine work. The customer needs a PDF, the system has the PDF, the only thing missing is a fast path from one to the other. A chatbot turns that path into a 30 second self-serve interaction instead of a five minute support task.

The math is simple. Fifty resends a month at five minutes each is 250 minutes of support time. Cut that to 10 percent of cases (the ones with address changes or VAT issues that need a human) and you save more than three hours of agent time monthly, with happier accounting customers on the other side.

Identity verification is the part that keeps this from being a security risk. Logged-in customers are scoped to their own orders. Unauthenticated requests need a one-time code sent to the email on file before any PDF goes out.

That single guardrail blocks the obvious harvesting attack where someone tries random order numbers. There is also a quiet brand benefit. B2B buyers especially expect modern self-serve.

When their accounting team can pull a year of invoices in one chat without filing a ticket, your store starts to feel less like a small operation and more like an enterprise vendor. That perception affects renewal and reorder rates in ways that are hard to measure but real. The data side closes the loop.

Logging every resend by user, order, and destination email creates an audit trail that finance can review. If the same customer pulls the same invoice 12 times in a month, that might be a signal worth a phone call.
