From email chaos to zero escalations — a custom ERPNext AP engine for INDmoney

INDmoney's accounts payable process had a structural problem that no off-the-shelf setting could fix: the entire vendor invoice lifecycle — receipt, approval, posting, payment, and vendor communication — was running on email. With hundreds of vendors, MSME compliance obligations, and a finance team processing invoices at fintech scale, the cracks were showing everywhere.

Invoices got lost in inboxes. L1 and L2 approvers had no unified view — they'd receive a PDF, download it, form their opinion in isolation, and reply by email. Treasury had no reliable way to know which invoices were approved and payment-ready. Vendors chased the finance team for payment advice. MSME payment timelines were tracked manually, if at all.

XLURSELF designed and built a fully custom Purchase Invoice Tracker on ERPNext — a purpose-built AP automation engine that transformed the entire workflow into a structured, trackable, auditable process from the moment an invoice arrives to the moment the vendor receives their payment advice.

The root cause wasn't a missing feature — it was the absence of a single system of record for the AP lifecycle. Vendors emailed invoices to individual finance team members. Approvers reviewed PDFs in their inbox with no context about purchase orders, previous invoices, or MSME status. The finance team manually keyed invoice data into ERPNext, duplicating work that already existed in emails. Treasury ran payment batches from a manually compiled list with no guarantee it was complete.

The consequences were predictable: service interruptions when payments were delayed, MSME compliance risk from missed statutory timelines, significant escalation volume from vendors following up on payment status, and finance team bandwidth consumed by coordination rather than control. No one had a single view of where any invoice stood at any moment.

XLURSELF built the Purchase Invoice Tracker — a custom ERPNext doctype that serves as the single document of record for every invoice, from receipt to payment. The solution centralised vendor invoice submission to a single email address, from which the AP team uploads invoices to the Tracker. Every invoice then flows through a structured L1 → L2 approval workflow on a purpose-built dashboard — a custom web page with Frappe JavaScript — where approvers see a summary view, can review the invoice inline without downloading, and approve or reject with a single action.

Once approved, one click from the finance team posts the Purchase Invoice in ERPNext with all relevant fields pre-populated from the Tracker — no re-keying, no duplication. Treasury runs a custom Payment Run report that surfaces all approved, payment-ready invoices and drives the payout process. The Tracker maintains the complete lifecycle status — approval stage, Purchase Receipt, Purchase Order, Purchase Invoice reference, and payment status — all in one document. Vendors access their payment advice directly from the dashboard: a richly formatted print format showing invoice count, TDS deducted, and GST paid. Daily automated alerts remind approvers of pending actions before timelines are breached.
