The problem

You don't need an ERP to send an invoice.

Running a small business is already complicated enough. You shouldn't have to learn complicated accounting software just to create a GST invoice.

“I want to invoice my customer. I don't want to become an accountant just to do it.”

  • ✕ Full accounting products can feel excessive when your primary need is invoicing.
  • ✕ Invoice creation can involve too many configuration steps.
  • ✕ Sending invoices and collecting payment are often disconnected.
  • ✕ Owners may have poor visibility into paid, due and overdue invoices.

Everything you need to invoice. Nothing you don't.

Built for small businesses that want to create GST invoices, send them instantly, track outstanding payments and follow up — without unnecessary accounting complexity.
