Features

Client Invoice Generation

Create professional GST-compliant invoices for your Indian service business clients directly from Avani's Invoice module — no Word templates or manual numbering required. Each invoice captures client name, GSTIN, billing address, line items with HSN/SAC codes, applicable tax rates (CGST/SGST for intrastate or IGST for interstate supply), and the final amount payable. Invoices are auto-numbered in sequence, satisfying GST record-keeping obligations. Service businesses, agencies, and consultancies can bill clients consistently and professionally from day one.

Payment Collection Tracking

Every payment received from a client is logged as a FinancialTransaction in Avani and linked back to the originating invoice. The module tracks the payment date, amount received, mode of payment (bank transfer, cheque, UPI), and any outstanding balance on the invoice. Partial payments are handled gracefully — the invoice status updates to Partially Paid, and the remaining receivable is visible at a glance. This gives your accounts team a live view of exactly what has been collected and what is still owed, without maintaining a separate Excel tracker.

Accounts Receivable Management

The receivables dashboard in Avani shows every outstanding invoice grouped by client, aging bucket (0-30, 31-60, 61-90, 90+ days overdue), and value. Finance teams in Indian SMBs can immediately identify which clients have not paid on time and prioritise follow-ups. The aging report replaces the manual weekly tally that most small business finance executives compile from scattered invoice copies. Reducing days sales outstanding (DSO) directly improves your working capital — critical for MSME businesses managing cash flow tightly.

GST-Compliant Invoicing with CGST/SGST/IGST

Indian businesses are legally required to issue GST invoices with the correct tax breakup — CGST and SGST for intrastate transactions, IGST for interstate supply. Avani automatically applies the correct tax split based on supplier and client state codes, so your invoices are always GST-compliant without manual calculation. HSN and SAC codes are stored against each service or product line, satisfying the mandatory GST invoice requirements under the CGST Act. MSME and startup founders no longer need to rely on their CA for every invoice they raise.

Client Account Statements

Generate a complete account statement for any client covering a selected date range — listing all invoices raised, payments received, credit notes issued, and the closing balance payable. This is the document your clients ask for when reconciling vendor payables at quarter end. Avani produces it in seconds from the Invoice and FinancialTransaction modules, formatted cleanly for sharing by email or PDF download. Agencies, IT service firms, and B2B businesses in India use client statements to settle disputes and accelerate payment approvals.

Invoice Status & Pipeline View

Every invoice in Avani carries a real-time status — Draft, Sent, Partially Paid, Paid, or Overdue. The billing dashboard shows the full pipeline: how many invoices are in draft, how many have been sent and are awaiting payment, and how many are overdue beyond the due date. Managers get a pipeline value total at a glance, similar to a sales pipeline but for billing collections. This eliminates the end-of-month scramble to figure out which invoices were sent and which were forgotten before the GST return filing deadline.

Revenue & Collection Analytics

Avani's finance analytics layer lets you visualise monthly invoiced revenue vs actual cash collected, client-wise billing concentration, and collection efficiency ratios. For service businesses and agencies in India, understanding which clients contribute the most revenue — and which have the worst payment track record — is essential for commercial decisions. Compare invoiced amounts against collected amounts by month to identify seasonal patterns and negotiate advance payments or retainers with habitually delayed payers.

Finance Ledger Integration

Invoices raised and payments received in the billing module post automatically to the correct ledger heads in Avani's FinancialTransaction module — debit Accounts Receivable on invoice creation, credit Revenue on invoice raise, and reverse the receivable on payment receipt. This double-entry logic eliminates manual journal entries by the accounts team and keeps the trial balance accurate in real time. Month-end reconciliation is faster and the finance team avoids the last-day rush to align the billing register with the accounts books.

Key benefits

How it works

  1. Raise a GST Invoice for the Client — Open the Invoice module in Avani, select the client, add line items with SAC/HSN codes and rates, confirm the tax type (CGST/SGST or IGST based on state of supply), review the auto-calculated tax amounts, and save or immediately dispatch to the client. The invoice gets a sequential number and is stored against the client record with status Sent.
  2. Record Payments as They Arrive — When the client pays — partially or in full — log the payment in the FinancialTransaction module, link it to the open invoice, enter the payment mode and date, and save. Avani updates the invoice status to Partially Paid or Paid, posts the transaction to the ledger, and reduces the receivable balance on the dashboard instantly.
  3. Monitor Receivables & Generate Statements — Use the receivables aging report to track overdue invoices and prioritise collections. When a client requests a statement of account, generate it for the desired period with a single click — all invoices, payments, and the closing balance are pulled together automatically, ready to share as a PDF.

Frequently asked questions

What is billing software and how does Avani Business OS handle client billing?

Billing software is a tool that enables businesses to create invoices for clients, record incoming payments, track outstanding receivables, and generate account statements — all in a single system. Avani Business OS includes a dedicated Invoice module and a FinancialTransaction module that work together to cover the full billing cycle: raise a GST-compliant invoice, dispatch it to the client, record payments when they arrive, and monitor the receivables aging report for overdue amounts. Indian service businesses, agencies, IT firms, and consultancies use Avani to replace ad-hoc invoicing from Word or Excel with a structured, audit-ready billing workflow.

Does Avani generate GST-compliant invoices with CGST, SGST, and IGST?

Yes. Every invoice raised in Avani's Invoice module includes the mandatory GST fields — supplier GSTIN, buyer GSTIN, place of supply, HSN/SAC codes per line item, and the tax breakup showing CGST and SGST for intrastate supply or IGST for interstate supply. The tax amounts are calculated automatically based on the configured rate and the state codes of the supplier and client. This ensures invoices comply with the requirements of the CGST Act and are accepted by clients for input tax credit claims without revision.

How does Avani track whether a client has paid an invoice?

Each invoice in Avani has a real-time status field — Draft, Sent, Partially Paid, Paid, or Overdue. When you record a payment in the FinancialTransaction module and link it to the invoice, Avani automatically recalculates the outstanding balance and updates the invoice status. Partial payments are tracked individually, so if a client pays in instalments, each payment is recorded against the invoice and the remaining balance is always visible. The receivables dashboard aggregates all open invoices and their ages across all clients.

Can I generate an account statement for a client covering a specific period?

Yes. Avani can produce a client account statement for any date range, listing all invoices raised, all payments received, any credit notes, and the net closing balance outstanding. This is the statement format that procurement and accounts payable teams in large client organisations request during vendor reconciliation at quarter end or financial year end. It is generated automatically from the Invoice and FinancialTransaction data in Avani — no manual assembly from scattered email threads or PDF invoices required.

What is the receivables aging report and why is it important for Indian SMBs?

The receivables aging report groups all outstanding invoices by how long they have been unpaid — typically into buckets of 0-30, 31-60, 61-90, and 90+ days overdue. For Indian MSME and small business owners, cash flow is the most critical operational variable. The aging report tells you exactly which clients are delaying payment and by how long, so the collections team can prioritise calls and follow-ups on the highest-value or most-overdue accounts. It also helps the management identify clients who are chronic late payers and consider whether to insist on advance payment or milestone billing for future work.

How does the billing module integrate with the finance ledger in Avani?

Avani's Invoice module is tightly integrated with the FinancialTransaction module. When you create an invoice, a receivable entry is posted to the ledger. When payment is received and recorded, the receivable is reduced and the bank or cash account is credited. This double-entry logic happens automatically — the accounts team does not need to make separate journal entries in a spreadsheet or accounting package for transactions originating in the billing system. The trial balance and P&L in the finance module are therefore always current without a manual month-end consolidation step.

Can I track billing and collections for multiple clients at the same time?

Yes. Avani maintains a separate invoice ledger and receivable balance per client. The billing dashboard shows all clients with open invoices simultaneously — sorted by overdue amount, invoice date, or client name as needed. Finance managers can drill into any client to see all open invoices, past payment history, and the current outstanding balance. For agencies and IT service firms in India that bill 20-50 clients per month, this consolidated multi-client view replaces the separate tracking files that finance teams typically maintain per client.

Is billing data in Avani suitable for GST return filing and audits?

Yes. Every invoice stored in Avani includes the mandatory GST fields — GSTIN of supplier and buyer, invoice number, invoice date, place of supply, HSN/SAC codes, taxable value, tax rate, CGST, SGST, and IGST amounts. This data maps directly to the fields required for GSTR-1 (outward supply return) filing. The sequential invoice register maintained by Avani serves as the books of accounts record for GST audit purposes. Indian SMBs can export invoice data for any period and share it with their CA or tax consultant for GST compliance without reconstructing records from email PDFs.

Does Avani support partial payments and multiple payment instalments per invoice?

Yes. When a client pays part of an invoice, you record the partial payment amount against that invoice in the FinancialTransaction module. Avani recalculates the balance due and marks the invoice as Partially Paid. Subsequent payments are added in the same way, each reducing the outstanding balance further. All payment transactions are timestamped and stored against the invoice, giving a complete audit trail of how and when the invoice was ultimately settled — useful for disputes and for reconciling bank statements with invoiced amounts.
