Short answer: TABSYST is an official ERPNext (Frappe) implementation partner delivering across India from HiLITE Business Park, Calicut — GST e-invoicing with IRN and QR, e-way bills, Tally migration and multi-state operations, with no per-user licence fees. ERPNext is built in India by Frappe Technologies of Mumbai, and its GST localisation is first-class because of it.
Most Indian mid-size businesses run Tally plus a constellation of spreadsheets — one tool for books, another for stock, WhatsApp for approvals, and nothing agreeing at month-end. An ERPNext implementation replaces the constellation, not just the accounting: sales, purchase, inventory, manufacturing, payroll and GST compliance on one ledger.
Tally is excellent at what it does — the problem is everything around it. The migration we run most often takes masters, ledgers and open documents across in a controlled cutover, reconciled against your Tally trial balance before go-live, so the first month in ERPNext starts from numbers your auditor already agrees with. The full method is in our Tally-to-ERPNext migration guide.
Our engineering team sits at HiLITE Business Park, Calicut. Across Kerala — Kochi, Ernakulam, Thrissur and Kozhikode — we implement on-site. Across the rest of India we deliver remotely with the same structure: discovery, staged configuration, migration, training, go-live support from named people.
We also build our own commercial products in the ERPNext (Frappe) ecosystem — Sellbee for van sales, Zappio, ZeroSKIP — so our engineering claims are verifiable in shipping software, not testimonials. Comparing partners? Our own guide to choosing an ERPNext implementation partner in India gives you the ten questions to ask — including about us.
No licence fees — cost is the one-time implementation, driven by modules, entities and data quality rather than user count. A single-entity Tally migration and a multi-state manufacturer are different projects, and honest pricing reflects that. We scope first, then quote fixed. For the wider market picture, see Best ERP Software in India and the best ERP companies in Kerala.
Hundreds of Indian-owned businesses run operations in the Gulf. The same ERPNext instance that files your GST carries UAE VAT and the 2027 e-invoicing mandate, Saudi ZATCA or Qatar's no-VAT regime — with group margin consolidated in one place. We run offices on both sides: Calicut and Dubai (DAFZ). How we bridge India and the UAE.
Yes — IRN and QR generation through the Invoice Registration Portal flow, e-way bills from the same delivery documents, and GSTR-ready reporting per registration. Multi-state businesses keep each GSTIN clean from one system.
Yes — it is the most common migration we do. Masters, ledgers and open documents in a controlled cutover, reconciled against your Tally trial balance before go-live. The full method is here.
Open-source with no per-user fees, mature GST localisation — and it is built in India, by Frappe Technologies of Mumbai, so Indian compliance is native rather than an afterthought.
No licence fees; the cost is the one-time implementation, driven by modules, entities and data quality. We scope first and quote fixed — a single-entity Tally migration and a multi-state manufacturer are different projects.
On-site across Kerala from our Calicut base at HiLITE Business Park; structured remote delivery across the rest of India, with training and support from the same named team.
Yes — separate GSTINs per state, inter-state transfers with e-way bills, branch P&L, and consolidated group reporting. Gulf entities run in the same instance with their own tax configuration.

What you should verify before signing with anyone, including us: (1) official partner status on the Frappe/ERPNext partner directory, not just a claim on a website; (2) a track record of shipping real software, not just configuring demos — ask to see something the team actually built; (3) named people who will still answer the phone after go-live, not a ticket queue. TABSYST is an official ERPNext (Frappe) implementation partner headquartered at HiLITE Business Park, Calicut, with a second office in Dubai (DAFZ). Beyond implementation, we build our own commercial products on the Frappe framework — Sellbee for van sales/DSD, Zappio for WhatsApp business messaging, and ZeroSKIP for school management — so our Frappe engineering depth is verifiable in shipping software used by paying customers, not only in sales claims.

Short answer: if your aggregate annual turnover has crossed ₹5 crore in any financial year since 2017–18, every B2B invoice, export invoice and credit or debit note must carry a valid IRN and signed QR code from the Invoice Registration Portal. The test looks backwards across all years, and once you are in scope the obligation is permanent — it does not lapse if turnover later falls.
Four changes decide whether an ERP is genuinely ready in 2026:
In practice, rejections are almost never a software problem. They come from master data: 4-digit or missing HSN where 6 digits are required above ₹5 crore, units of measure that are not on the prescribed UQC list, cancelled or mistyped customer GSTINs, wrong place of supply producing IGST where CGST and SGST belong, and item tax templates never re-checked after the September 2025 rate restructure. Every implementation we run starts with that audit before a single live invoice is raised.
Compliance dates are published by the GSTN and CBIC and do change — verify the current position against the latest advisory before acting.
GST stopped being a filing exercise and became an operating constraint. Five changes decide whether an ERP configuration survives contact with the portal:
Rarely the integration. Almost always the master data: HSN/SAC codes missing or truncated, units of measure that are not valid UQCs, invoice naming series longer than the 16-character limit the portal allows, customer GSTINs that were never validated, and wrong export / SEZ / reverse-charge flags that only surface at GSTR-1 reconciliation. We clean all five before cutover, against your Tally data, rather than discovering them on your first live invoice.
Indian GST functionality lives in the separate open-source India Compliance app installed alongside ERPNext — it provides GSTIN validation, IRN generation through a GSP, e-way bills, GST reports and GSTR-2B purchase reconciliation. It is free software; the only recurring cost is your GSP/API arrangement, not a per-user licence. Figures and dates above are as published up to late 2026; confirm current applicability for your turnover band with your CA.
