Send a customer an invoice and Slash emails it with a PDF and a payment page, reminds them as the due date approaches, and records the money against the invoice when it arrives.

Create and send

Issue, schedule and edit invoices.

Collect payment

Match deposits and record payments.

Recurring invoices

Bill a customer on a schedule.
Invoicing has to be turned on for your business; customers work either way.

​
Customers

Every invoice is billed to a customer: the business or person you invoice, and the email address invoices and reminders go to. Create a customer once and reuse it on every invoice and series. An invoice keeps the billing details it was issued with. After you update a customer, existing invoices pick up the change only when you edit them. Archive customers you no longer bill; their invoices are left as they are.

​
Invoice lifecycle

You never set an invoice’s status. Creating, sending and voiding move it, and once it’s sent Slash recomputes it from its payments whenever one is recorded, removed or returned.
Invoice lifecycleInvoice lifecycle
  • An invoice can be edited while it’s scheduled or unpaid. Once it has a payment, void it and issue a new one instead.
  • An invoice past its due date with money still owed is flagged overdue; its status doesn’t change.
  • void is final. A voided invoice can’t be paid, edited or reminded.
Each invoice’s PDF is a document: documentId points to the current version, and every edit renders a new one.
