Job description

Protect cash flow: Own the invoice-to-cash engine so that every rupee of work delivered is billed accurately, on time and converted to cash, funding a business that is scaling fast.

Plug revenue leakage: Make sure nothing slips through: no unbilled jobs or missed milestones, no short-recovered GST/TDS, no lapsed BG/LC and no export proceeds stuck beyond FEMA timelines.

Bring DSO down, make receivables predictable: Cut disputes at source, keep customer ledgers clean and feed reliable collection forecasts to leadership.

Build billing for scale: Turn a manual, Excel-heavy process into an automated, analytics-led and audit-ready function that can handle multi-fold volume growth without adding headcount at the same rate.

II. Key Results and Activities

Review customer PO / contract, pricing, milestones, payment and tax terms before every invoice.

Generate invoices for spares, services and projects in SAP using a pre-billing checklist (PO match, service report / completion proof, internal approval).

Apply correct GST (place of supply, LUT exports, SEZ), generate IRN / e-way.

Compile the complete invoice kit (timesheets, service reports, DC, e-way bill) and upload / submit on customer portals within TAT with 100% accuracy.

Run a weekly unbilled-revenue review with Delivery / Projects and close gaps before month-end.

Raise credit / debit notes only with approvals, and tag the root cause of each one.

• Publish a customer-wise AR ageing and overdue tracker every week, with DRI and next action, to Sales / Delivery.
• Apply receipts, clear unapplied cash and resolve bank queries on receipts, SWIFT advices and bank charges daily.
• Issue monthly SOAs, obtain quarterly balance confirmations and reconcile customer ledgers (short payments, deductions, TDS).

• Manage BG / LC lifecycle, LC documentation and bill discounting with banks
• Match inward remittances to invoices, obtain FIRC / e-BRC and close EDPMS entries as per FEMA / RBI norms.
• Handling & tracking of Cores (refurbished inventory).
• Assess credit exposure and recommend changes required in credit policies, advances or LC terms.

3.Billing Automation, AR Analytics & Readiness for Scale

• Map the order-to-cash process, identify manual steps and drive automation with the BA / AI team (auto-invoicing from ERP, SOA / reminder mailers, portal uploads).
• Build AR analytics (DSO trend, collection effectiveness, dispute root causes, customer-wise risk) and feed cash forecasts to FP&A.
• Write SOPs and maker-checker controls so that billing volume can grow multi-fold without headcount growing at the same rate.
• Keep customer master data clean (GSTIN, credit terms, billing contacts) and support improvements to the ERP / SAP billing module.
