ARUKZ ERP does not yet talk to the government portals directly, does not generate PF and ESI return files, shows module screens and prints in English only, and does not stop an expired batch from being delivered. Those are the gaps most customers ask about; the full list is below, grouped by area, so you can check what matters to your business before you start. Each module page has its own "What it does not do yet" section with the detail. ## GST and tax | Not built yet | What you do instead | | - | - | | Sending invoices to the IRP for an IRN | Download the e-invoice JSON for a posted invoice, upload it on the IRP, and record the IRN in ARUKZ ERP. See [E-invoice and e-way records](https://docs.erp.arukz.com/gst/e-invoice-and-e-way.md). | | Generating e-way bills | Generate them on the e-way bill portal and record the number on the delivery or invoice. | | Filing GST returns | ARUKZ ERP prepares the figures and files (GSTR-1, GSTR-3B figures, GSTR-2B match, ITC-04); you file on the GST portal. See [GST returns](https://docs.erp.arukz.com/gst/returns.md). | | TDS on vendor bills, filed returns | The TDS register records deductions, challans and quarterly data; you file the TDS returns yourself. See [TDS](https://docs.erp.arukz.com/gst/tds.md). | | Export deadline alerts | No alerts yet for the 3-month export rule or for realisation of export proceeds. Also not built: IGST refund (RFD-01) workings, bank or exchange-difference posting from the realisation, IEC and RoDTEP tracking. See [Exports under LUT](https://docs.erp.arukz.com/gst/exports-lut.md). | > [!NOTE] > > The e-invoice JSON and online payments through Razorpay have been tested against recorded shapes of those services, not against a live account. Check your first e-invoice upload on the IRP carefully. ## Payroll and people * **PF ECR and ESI return files** are not generated. The payroll run works out the employee and employer shares; you file on the EPFO and ESIC portals. See [Payroll](https://docs.erp.arukz.com/modules/payroll.md). * **Payroll is not posted to the books** as journal entries yet, professional tax slabs by State are not built, and there is no payslip PDF. ## Stock, production and quality * **An expired batch is not blocked at delivery.** Lots carry an expiry date and the lot list filters expired and expiring lots; check it before you dispatch. See [Lots and batch expiry](https://docs.erp.arukz.com/modules/lots-and-expiry.md). * **Stock Summary needs the "Stock in the ledger" module**, which posts stock movements to the books. See [Day Book, Ledger and Stock Summary](https://docs.erp.arukz.com/modules/day-book-ledger-stock-summary.md). * **PPAP and SPC** are not built in Quality. * **Depreciation** of fixed assets is not calculated automatically. * **Duplicate detection and merge** for customers, suppliers and products is not built; search by GSTIN before you add a party. ## Accounts and the Tally-style books * **Contra (F4) opens a journal entry**, not a separate contra voucher. * **No Enter-to-next-field**, no drill-down from the Stock Summary into vouchers, and no Alt+F2 period change. * **The Tally import brings masters and opening balances, not past vouchers**, bill-wise outstanding, or stock by godown or batch. See [Moving from Tally](https://docs.erp.arukz.com/get-started/moving-from-tally.md). * **Direct bank feeds and UPI payment links** are not live; bank statements are imported from a file. See [Banking](https://docs.erp.arukz.com/modules/banking.md). ## Language and screens * **Tamil and Hindi** cover sign-in, menus, buttons, tables, notifications and the dashboard. Module screens and printed documents (invoices, challans) are still in English. See [Languages](https://docs.erp.arukz.com/admin/languages.md). * There is **no mobile app**; ARUKZ ERP runs in the browser on a phone or tablet. * There are **no per-role home layouts** yet; everyone sees the same home screen, limited to what their role can open. ## AI * **Ask AI and MCP are read-only.** They cannot post, change or delete anything. See [Ask AI](https://docs.erp.arukz.com/ai/ask-ai.md). * **A read-only workspace gets no MCP access** (the server answers 402). * **AI allowances per plan and your own model key** are being rolled out. See [AI allowance and your own key](https://docs.erp.arukz.com/ai/allowance-and-own-key.md). ## Industries it is not built for ARUKZ ERP is built for manufacturers and traders. It has no counter-billing (POS) screen, and is not built for jewellery (weight and purity stock, karigar ledger, HUID), healthcare, education or contractor billing. EPR returns for plastics, e-waste and batteries, FSSAI returns, a garment size-colour matrix, distributor beat planning and marketplace settlement import are not built. It is not validated for regulated GMP use. See [Industries](https://docs.erp.arukz.com/industries/overview.md). ## Hosting and records * **Backups** are taken every night and the last fourteen are kept, on the same server. Encrypted off-server copies and a daily backup copy on servers in India are not live yet. See [Security and data](https://docs.erp.arukz.com/security.md). * **Privacy, terms and refund pages** are not published yet. Ask ARUKZ DIGITAL for the terms that apply to your account. * **Subdomains** such as `yourcompany.erp.arukz.com` are not offered; each company has its own path, `erp.arukz.com//admin`. See [Your company's address](https://docs.erp.arukz.com/admin/company-address.md). > [!TIP] > > If one of these blocks you, tell ARUKZ support before you sign up for a paid plan.
