Invoices
31 step-by-step guides for invoices.
Send payment reminders
Chase unpaid invoices on their own with an automatic follow-up schedule, or schedule a single reminder for a specific day. Both are set up here.
Save your products and services for reuse
Save the things you sell once, with a name, description and price, and pick them on any invoice or quotation instead of typing them again.
Bill a client in their own currency
Invoice a client in the currency they pay in, while your own books stay in your firm's currency. This guide shows how the currency and exchange rate work.
Tag a line to a service for accurate revenue reports
Each invoice line can be tagged to one of your services behind the scenes. This is what makes a bundled invoice split correctly across services in your revenue reports, and it never shows on the client's PDF.
Set the invoice date and payment terms
The invoice date defaults to today, and you can change it or back-date it. Payment terms set the due date for you, from Due on receipt to Net 90 days or a custom date. Here is how both work.
Set the currency on an invoice
An invoice uses your firm's currency by default. For a saved client it locks to that client's billing currency, and only a brand-new lead can pick the currency on the invoice itself.
Why an invoice shows as overdue
Every invoice is due 30 days after its invoice date. Once that date passes and the invoice is still unpaid, IzzyTap changes its status from Sent to Overdue and shows a red chip. Here is exactly how that works and what to do about it.
Choose which bank account a payment goes into
When you record an offline payment, IzzyTap lets you note how the money arrived and, if your books are switched on, which bank or cash account received it. This keeps your accounts accurate and makes reconciling your bank far easier later.
Issue a credit note against an invoice
Raised an invoice by mistake? Issue a numbered credit note against it. The invoice is voided, the balance owed drops to zero, and your books are corrected with a clean reversing entry. Only unpaid invoices can be credited this way.
Undo a credit note issued by mistake
Issued a credit note against the wrong invoice, or credited an invoice you should not have? Cancel the credit note. It reopens the invoice it voided, unwinds the credit from your books, and keeps a full audit trail.
Cancel, credit note or refund: which one to use
There are three ways to undo an invoice, and they are not interchangeable. Which one is allowed comes down to a single question: has the client paid yet?
Why an invoice is missing from the credit-note list
The credit-note screen only lists invoices it can actually reverse. If the one you want is missing, here are the four reasons why, and how to fix each.
