Retail, POS and B2C teams running on ERPNext hit a wall when they try to run a real retention program. ERPNext ships a native Loyalty Program DocType with a single earn rate and a fixed redemption factor per tier, but it stops short of the mechanics modern loyalty needs: no rules for earning on specific actions or referrals, no true reward catalog with redeemable SKUs or vouchers, no configurable expiry buckets, and no clean earn/burn experience at the e-commerce checkout. Most teams end up tracking points in spreadsheets or bolting on a disconnected third-party app that never reconciles back to the customer ledger.

We build a dedicated Frappe app that lives inside your ERPNext instance and treats loyalty as first-class data. The app introduces its own module and DocTypes — a Loyalty Rule engine (earn on spend, on defined actions such as signup, review or birthday, and on successful referrals), Loyalty Tier definitions with escalating multipliers and benefits, a Reward Catalog of redeemable items or vouchers, and a per-customer Points Ledger Entry that is the single source of truth for balance, accrual and expiry. Points accrual is driven by hooks.py document events: on_submit handlers on Sales Invoice and POS Invoice evaluate the active rules, compute earned points against the tier multiplier, and write immutable ledger entries — mirroring how ERPNext's own GL and stock ledgers work, so every point is traceable to a source document.

Redemption and balance logic is exposed through whitelisted server methods (@frappe.whitelist()) callable from the POS and from your storefront over the Frappe REST API, so a cashier or a web checkout can quote a balance, apply a burn, and post the redemption atomically without letting a customer overspend. Client scripts surface points earned and available on the Sales Invoice and POS forms; a scheduler event (a nightly scheduler_events cron) ages and expires points according to your configured windows and can trigger balance-reminder notifications. Role profiles and DocType permissions keep rule configuration, manual point adjustments and catalog management scoped to the right staff, with every adjustment captured for audit.

Because this is build-to-order, nothing is a generic download. We start with a short scoping call to map your earning rules, tier structure, expiry policy and the exact POS and e-commerce touchpoints, then build against your ERPNext version (v15 or v16). You get the app installed on a staging bench first for UAT, a documented rollback path, and a defined post-go-live support window. Typical delivery is one working week from confirmed scope, and the full git repository is handed over so the app is yours to run and extend.
