BillSetu – User Guide
We are pleased to introduce BillSetu, a powerful invoicing
and revenue management module within Spectrum Cloud. BillSetu is designed
to streamline billing workflows, enhance financial visibility, and ensure
statutory compliance in document generation.
With an intuitive interface and automation-driven features,
BillSetu enables professionals and firms to efficiently manage invoicing, track
payments, and maintain accurate financial records.
Key Features and Highlights
- Real-Time WYSIWYG Invoice Builder: BillSetu offers a real-time WYSIWYG (What You See Is What
You Get) builder, allowing users to create invoices with a live
side-by-side preview. As users edit invoice details, they can instantly
view how Invoices, Credit Notes, and Debit Notes will appear in the
final document.
- Smart GST & Statutory Compliance: The system automatically ensures GST compliance by
intelligently identifying Taxable and Non-Taxable invoices. It
calculates IGST or CGST/SGST based on the Place of Supply (POS) and also supports the Reverse Charge Mechanism (RCM) where applicable.
- Dynamic UPI QR Codes: Invoices generated in BillSetu automatically include dynamic
UPI QR codes with the exact payable amount, enabling faster, convenient,
and error-free payment collection for clients.
- Custom Professional Branding: Users can personalize their billing documents with custom
theme colors, firm logos, and digital signatures to maintain professional
branding. If branding elements are not configured, the system
automatically applies the standard CA Authentic Logo as a fallback to
maintain document authenticity.
- Automated Client Synchronization: Client data is automatically synchronized from the Spectrum
Cloud platform, ensuring consistent client information across modules. Additionally, historical invoicing records remain preserved
even if a client is later removed from the primary client directory.
- Comprehensive Client Ledger & Dashboard: BillSetu provides a centralized dashboard that offers
complete financial visibility at both firm and client levels. Users can track key financial metrics such as:
- Total
Billed Amount
- Amount
Received
- Opening
Balances

Exposure
This helps firms monitor outstanding receivables and overall
billing performance.
- One-Click Document Sharing: Invoices can be instantly shared with clients through:
- WhatsApp
- Professional
PDF invoices
This enables quick and seamless document communication.
- Integrated Payment Tracking: BillSetu allows users to record partial or full payments
against invoices. Based on the recorded payments, the system automatically
updates the invoice status to:
- Unpaid
- Partially
Paid
- Paid
This ensures accurate tracking of receivables.
- Secure Audit Trail & Cancellation Workflow: To maintain financial accuracy and audit integrity:
- Issued
invoices cannot be deleted.
- Recorded
payment entries are protected from deletion.
- Draft invoices can be deleted before they are issued.
If an invoice needs to be invalidated, a structured
cancellation workflow is provided, requiring users to select a mandatory
cancellation reason.
- GSTR-1 Ready Export: Users can export the complete invoice ledger in Excel
format, structured to support GSTR-1 filing requirements,
simplifying GST compliance and reporting.
- ICAI Fee Guidelines Integration: BillSetu provides a direct in-application reference to
ICAI recommended fee guidelines, helping professionals standardize service
pricing and maintain industry-aligned billing practices.
