Every UAE employer on the Wage Protection System must submit a Salary Information File (SIF) to their bank or exchange house each pay cycle, in the exact fixed-width, agent-coded format MOHRE and the Central Bank mandate. ERPNext ships a solid Payroll Entry and Salary Slip engine, but it stops at the ledger: there is no native DocType that emits a compliant .SIF, no Employer/Agent routing-code registry, and no pre-submission validator for IBAN, Molid, or Labour Card fields. Finance teams end up exporting slips to a spreadsheet, pasting them into a bank-supplied WPS template by hand, and discovering formatting rejections only after the file bounces — which risks late-wage penalties and MOHRE flags.

ECOSIRE builds a proper Frappe app — ecosire_uae_wps — installed onto your existing ERPNext site as a first-class module, not a fragile export macro. At its core is a WPS SIF Export DocType that reads a submitted Payroll Entry, walks its linked Salary Slip records, and assembles the SIF in the correct three-part structure: the Salary Control Record (SCR) header carrying employer routing code and total-salaries control totals, one Employee Detail Record (EDR) per worker, and the trailing footer with record counts and value checksums. A companion WPS Agent DocType holds each bank/exchange-house routing code and its IBAN prefix rules, so multi-bank employers map the correct agent per company or per employee. Generation runs through whitelisted server methods (@frappe.whitelist()) callable from the Frappe REST API or a scheduler event, so a monthly run can be automated end to end.

The compliance logic lives where it belongs — in the app's Python. hooks.py doc events (on_submit, validate) fire a pre-submission validator that checks every EDR field before a file is ever produced: IBAN length and checksum (mod-97), Molid/Labour Card presence, pay-period date bounds, and control-total reconciliation between the header and the sum of detail rows. UAE Labour Law gratuity and end-of-service benefit are computed with a dedicated calculation that respects limited vs. unlimited contract rules, 21-day vs. 30-day accrual bands, and capped-service ceilings, and can be surfaced on the Salary Slip via a client script. Role-based permissions (a WPS Officer role profile) gate who can generate and download files, and every export writes an immutable audit-log row — file hash, period, record count, generated-by, and timestamp — so any SIF can be re-exported byte-identically or traced during an inspection.

Because this is build-to-order, nothing is a black box. After a short scoping call we confirm your exact bank agents, contract types, and salary-component mapping, then build against your Frappe/ERPNext v15 or v16 site. You receive the full app source in a git repository, a staging UAT pass against a copy of your real payroll data, installation and configuration on your environment, and a post-go-live support window. Typical delivery is one working week from confirmed scope. You own the code and can extend it — ECOSIRE simply gets you to a first correct, audited SIF submission without the spreadsheet gymnastics.
