Forward invoice or statement
Sales or finance forwards invoice PDFs, delivery notes, or customer messages to Stackifier on WhatsApp.
Customer, invoice number, amount, due date, and status are added to the billing record.
Customers ask for statements, delivery updates, invoices, and receipts in WhatsApp. Stackifier checks the record, reads payment proof, and helps the business answer from the latest facts.
Best first pilot: repeat customer follow-up, with statement PDFs, payment slip matching, delivery questions, and approved WhatsApp replies.

Why this workflow exists
Stackifier gives the scattered parts a record, a status, and a safe next step.
Invoices, delivery notes, and payment slips sit across sales reps, finance chats, and customer WhatsApp threads.
Customers say they paid, but finance still has to match screenshot proof to the right invoice and account.
Trade customers need polite reminders, but staff hesitate because the latest promise-to-pay is buried in chat.
Owners need a daily unpaid list by customer, ageing, collector, and amount without rebuilding the sheet by hand.
