On Pro, open a non-voided Naira sales invoice and choose Make recurring. Set the first date, weekly, monthly, quarterly or yearly frequency, payment due offset, and whether WadMaster should email each generated invoice. Review the next dates before saving; a day from 29 to 31 moves to the last valid day in shorter months and returns when a later month allows it.
Each occurrence is a new normal invoice with its own number, balance, payment link and history, and it uses the normal monthly invoice allowance. From Invoices -> Recurring you can edit future line items, pause or resume, skip the next occurrence, generate the next invoice early, or end the schedule. Existing invoices never change when the schedule is edited.
Go to Invoices and choose Create invoice. Select or add a customer, add inventory products or custom line items, set the invoice and due dates, choose whether it is already paid or still due, and select Create invoice. If the customer has an email address, you can email it during creation. From the saved invoice, use Share to send it through another app, WhatsApp, email, or copy the private invoice link.
Online payment is optional, not automatic on every invoice. For an unpaid Naira invoice, turn on Add a payment link after adding the customer's email, completing KYC, and adding the bank account where settlements should go. Choose whether the link requires the full outstanding balance or lets the customer choose a partial amount, and optionally set a minimum partial payment. The customer opens the invoice link and completes the Paystack checkout using a method Paystack offers, such as card, bank transfer, or USSD. If online partial payment is enabled, the customer can enter an allowed amount or use the full balance; otherwise checkout charges the full remaining balance. Online payments must meet the NGN 50 provider minimum, a seller's optional minimum, and cannot leave less than NGN 50 unpaid. WadMaster updates the cumulative paid and remaining amounts after confirmation. Manual and online part-payments can happen one after another, but manual recording and policy changes pause while a checkout is active.
On Home, find the overdue invoice queue and select Remind. WadMaster emails the customer a payment reminder with the invoice link. The invoice must be unpaid, past its due date, and have a customer email address. A successful invoice email or reminder starts a 24-hour cooldown before another can be sent. To send a message yourself on WhatsApp, open the invoice and use Share; that is separate from the email reminder.
