InvoiceNow readiness

Timeline

8 Weeks

Primary Stack

Business Central + integrations

Where the operational pressure showed up

The finance team was managing GST treatment and invoice preparation through a combination of ERP exports, manual tax checks, and quarter-end spreadsheet clean-up. As InvoiceNow timelines approached, they needed confidence that invoice data, tax mapping, and approval ownership were ready for structured submission rather than best-effort reconciliation.

Pressure points

  • Tax codes were inconsistent across customer and item records
  • Approval paths differed by entity and invoice type
  • Quarterly GST prep depended on manual reclassification
  • There was no single view of filing readiness across finance and operations

How the delivery model closes the gap

APSS redesigned the workflow from transaction source to compliance output. The representative solution combined Business Central configuration, cleaner tax rules, approval checkpoints, and readiness reporting so the finance team could see exactly which records were safe to submit and which required intervention.
