Billing Booster

Billing Booster

Developed By BlueRabbIT

Compatible with WHMCS v9.0

Get Paid Faster, Reconcile Less

An invoice that is awkward to pay gets paid late. A payment that arrives without a usable reference costs you a manual reconciliation. Billing Booster deals with both ends of that.

It is really three tools in one module — scannable payment codes, machine-readable e-invoices, and automated bank reconciliation. They work well together, but none of them needs the others, so you can take just the part your billing is missing.

Conditional rules decide which invoice gets which code or format, by currency, country or gateway — so a Swiss client receives a QR-bill and a German business client receives a ZUGFeRD file, out of the same WHMCS invoice run. We build it, use it for our own billing, and answer our own support.

Three Features, One Module

Each one stands on its own. Switch on the parts your billing is missing and leave the rest off.

  • Payment codes — Scannable QR and reference codes on invoices, emails and the payment page.
  • E-invoicing — Machine-readable XML in ZUGFeRD / Factur-X, UBL 2.1 and Peppol BIS.
  • Bank reconciliation — Statements downloaded automatically, payments matched to invoices.

Solo unlocks any one of the three, Duo any two, Trio all three. You pick which ones directly in the module after purchase, so you only pay for what you actually use.

Everything Your Invoice Run Has Been Missing

  • Payment codes: EPC/SEPA QR, Swiss QR-bill, SPAYD, HUB3, VeriFACTU
  • Embedded in PDF invoices, invoice emails and the payment page
  • E-invoicing: ZUGFeRD / Factur-X, UBL 2.1 and Peppol BIS
  • Automatic bank statement download and import (PostFinance MFTPF, CAMT.054)
  • Incoming payments matched back to the right invoice automatically
  • Conditional rules by currency, country and payment gateway
  • Licensed by feature — Solo, Duo or Trio, so you pay for what you use
  • Integrates with BlueRabbIT BestPDF for pixel-precise placement
  • Integrates with BlueRabbIT Pingen Post for QR-bill invoices by post
  • Actively maintained & professional support
