Evaluate invoices, GST-ready calculations, receipts, multi-invoice allocation, advances, collections, expenses and business reports in a Zerolink RMS trial workspace.
Professional invoices
Create customer invoices with products or manual line items, discounts, tax calculation, payment QR, bank details and controlled print or PDF output.
Receipts and allocation
Record one payment receipt and allocate it to one or several eligible invoices while preserving customer outstanding and ledger context.
Collections and advances
Follow overdue invoices, reconcile unmatched receipts and keep advance amounts separate from invoice outstanding.
Expenses and reports
Record business expenses and review accounting reports, GST preparation data and profit-and-loss context according to configured permissions.
Controls to validate
- Company GSTIN, state codes and CGST/SGST or IGST behavior.
- Invoice numbering, payment allocation, reversal and audit history.
- Invoice print, PDF, current-sheet export and customer portal payment flow.
Trial and compliance note
- The 90-day trial helps evaluate the software; it is not professional tax or legal advice.
