Most finance teams track corporate fixed deposits in a spreadsheet that lives outside ERPNext entirely. The FD certificate sits in a drawer, interest income is only recognised when the bank statement arrives, and nobody notices a maturity until the renewal window has already closed. ERPNext core has no Fixed Deposit DocType — you can post a manual Journal Entry against a bank asset account, but there is no register of principal, rate, tenure or maturity, no scheduled accrual, and no way to see your bank-wise exposure at a glance. The moment auditors ask for accrued-but-not-received interest, or the treasury wants to know how much matures next quarter, the spreadsheet and the ledger disagree.

The Fixed Deposit & Investment Tracker is a proper Frappe app that ECOSIRE builds for your ERPNext site. At its core is a Fixed Deposit DocType holding the deposit number, bank (linked to your existing Bank and Bank Account records), principal, interest rate, compounding basis, deposit and maturity dates, and the GL accounts to post against. A hooks.py doc-event on submit validates the schedule and creates the opening entry that moves funds from your operating bank account to an FD asset account. Interest is recognised automatically: a scheduler_events daily/monthly job walks active deposits, computes accrued interest for the period, and posts a Journal Entry (debit interest-receivable, credit interest income) so your accrued-interest balance is always live rather than reconstructed at year-end.

On top of the accrual engine we build the operational layer finance actually uses day to day. TDS (or withholding tax) on interest is computed at the configured rate and split into a payable account on each accrual, so your Form 26AS / withholding position reconciles without manual adjustment. A scheduler_events reminder job raises maturity and renewal alerts a configurable number of days ahead — via ERPNext Notifications, email, and optional ToDo assignments to the treasury owner. A Query Report gives you a bank-wise FD register (principal, accrued interest, TDS, maturity date, days-to-maturity) with drill-through to each deposit, and whitelisted methods expose the same data over the Frappe REST API so a treasury dashboard or Insights chart can read it. Everything respects Frappe permissions: a dedicated role profile lets a Finance Manager create and submit deposits while restricting posting rights, and every generated Journal Entry carries an audit trail back to its source deposit.

Because this is build-to-order, nothing is a black box. We start from your actual chart of accounts, deposit types and TDS rules, agree the accrual and rounding conventions in writing, then build the app against Frappe/ERPNext v15 or v16 to match your site. You receive the installable source, we install and configure it on staging for UAT, then deploy to production with a rollback plan. This is not an anonymous marketplace download — it is a scoped engagement where ECOSIRE builds exactly the FD and investment workflow your treasury runs, and stands behind it afterwards.
