For nearly a decade, Indian IT/ITES, BPO, and consulting firms billed offshore clients through intermediary arrangements while still paying 18% domestic GST — an anomaly that made Indian exporters structurally less competitive than global peers. That changed on 30 March 2026, and finance teams running Odoo now have a narrow window to get their GST and export invoicing logic right before compliance gaps compound.

What Changed Under Section 157, and Why It Matters to Exporters

The Finance Act, 2026, which received the assent of the President on the 30th day of March, 2026, has finally put this long-standing controversy to rest by omitting clause (b) of sub-section (8) of Section 13 of the Integrated Goods and Services Tax Act, 2017 through Section 157 of the Finance Act, 2026. Under the old rule, Section 13(8)(b) of the IGST Act deemed the place of supply of intermediary services to be the location of the supplier, so where an Indian intermediary renders facilitation services to an overseas customer, the place of supply is deemed to be in India merely because the supplier is located in India, resulting in domestic GST being charged and disqualifying such supplies from export status and zero-rating. This affected a broad swathe of the export economy: IT/ITES companies, global capability centres, business process outsourcing units, consulting firms, and marketing support entities providing facilitation services to overseas clients.

Post-amendment, the place of supply for intermediary services falls under the default rule of Section 13(2), i.e., the location of the recipient. Practically, this means if an Indian agent arranges a deal for a UK-based company and gets paid in British pounds, the place of supply is now the UK, and the transaction qualifies as an export of service under Section 2(6) of the IGST Act.

Two timing details matter for compliance planning:

  • Effective date is now, not retrospective. The Finance Act 2026 received Presidential assent on 30 March 2026, making that date the effective date of the change. The omission takes effect from 30 March 2026 and is not expressed as retrospective, so past periods rest on the arguments that already existed.
  • It cuts both ways. The relief isn't one-directional. Indian businesses engaging foreign agents, brokers, or commission agents are now required to self-assess and pay IGST under RCM at 18% on such payments, with a self-invoice issued under Section 31(3)(f) of the CGST Act. Indian recipients must self-assess and discharge IGST under RCM, creating additional tax incidence particularly in sectors with restricted or ineligible ITC such as hotels, airlines, petroleum entities, and financial services procuring services from overseas booking agents, cargo intermediaries, or securities brokers.

This is distinct from — and layered on top of — the GST 2.0 rate-slab rationalization many Odoo users already absorbed. That was a rate change. This is a place-of-supply and export-classification change, which touches a different set of configuration objects entirely: fiscal positions, tax mapping on customer/vendor records, and invoice-level GST treatment tags.

Why This Demands an ERP-Level Audit, Not Just an Accounting Memo

A GST law change of this nature doesn't self-correct inside an ERP. Odoo's India localization is comprehensive, but it is rules-driven: it applies logic based on how master data and fiscal settings are configured, not based on what the law currently says. As one detailed implementation guide puts it, everything exists in Odoo, but none of it works correctly without the right configuration being done first, in the right sequence, before the first invoice goes out.

For intermediary-service exporters, three areas typically need re-mapping:

  • Fiscal positions and tax mapping on every overseas customer classified as receiving intermediary/facilitation services — these were likely hardcoded to apply IGST as a domestic-equivalent tax under the old supplier-location rule.
  • Place-of-supply and GST treatment tags on sales journals and invoice templates, so exports now flow correctly as zero-rated rather than taxable.
  • LUT (Letter of Undertaking) and export documentation settings, since zero-rating for exports under GST is conditional. Taxpayers should execute or renew a Letter of Undertaking for zero-rated export of intermediary services.

Odoo's own mechanics reinforce why this matters: Odoo applies IGST automatically based on state codes, with no manual switching, and export invoices can be marked as zero rated, with Odoo tracking them separately for reporting and compliance. If the underlying fiscal position or customer tax mapping still reflects the pre-amendment "supplier location = India" logic, invoices will keep generating incorrect GST — either overcharging clients who are now entitled to zero-rated treatment, or worse, under-reporting RCM liability on inbound intermediary services.

The Inbound Side: RCM Exposure Most Finance Teams Are Missing

Most commentary on this amendment focuses on the upside for exporters. But CFOs procuring services from foreign agents, brokers, or facilitators — common in trading and consulting firms with overseas sourcing arrangements — now face new self-assessment obligations. Since the supplier is located outside India, there will be two invoices in cross-border intermediary service transactions: a commercial invoice issued by the foreign supplier, and a self-invoice issued by the registered Indian recipient, with the date of the self-invoice being the relevant reference point for taxability and credit.

Inside Odoo, this requires configuring self-invoicing workflows and RCM tax rules that may not have existed in the chart of accounts before — not a toggle switch, but a genuine functional build-out involving journal entries, vendor bill sequences, and ITC eligibility mapping.

Getting the Configuration Right Before It Becomes a Liability

The window between legislative change and enforcement scrutiny is exactly when misconfigurations compound into filing mismatches, GSTR-1/GSTR-3B discrepancies, and denied refund claims. If there are missing fields, incorrect GSTINs, or tax mismatches, Odoo flags them before export, allowing finance teams to fix issues at source instead of discovering them after portal rejection — but only if the underlying tax logic was set up correctly in the first place. A tool that surfaces errors is only useful if the configuration behind it reflects current law.

Grey Space Computing, an Odoo Ready Partner serving mid-market exporters, BPOs, and consulting firms across India, the GCC, and the US market, has been running exactly this kind of functional audit for clients since the amendment took effect — reviewing fiscal positions, customer/vendor tax mapping, LUT documentation, and self-invoicing setups against the new Section 13(2) default rule. Waiting until the next GST filing cycle exposes mismatches is the costlier path.

If your finance team is unsure whether your Odoo instance correctly reflects zero-rated export treatment for intermediary services — or whether your inbound RCM exposure is properly captured — talk to GSC about an Odoo GST configuration audit as part of our implementation and migration services. Getting this right now protects both your compliance posture and the refund and cash-flow benefits this amendment was designed to unlock.
