An Indian IATA-accredited travel agency reconciles a weekly BSP-link settlement against GDS booking files (Amadeus, Sabre, Galileo) per ticket per airline, manages a Refund Application + ADM/ACM cycle with airline-initiated dispute windows, holds a GST split between 5 percent tour-operator (Notification 11/2017 entry 23) and 18 percent agency commission (SAC 998551), and chases lagged airline-incentive TDS under Section 393 code 1007 across 22+ deductor airline TANs. The reconciliation must hold ticket-number granularity from GDS issuance through BSP weekly settlement through bank-statement debit, with ADM/ACM ageing and incentive-receivable chase live concurrently.
Build a per-ticket master from GDS issuance files keyed by ARN, ticket number, PNR, airline code, fare basis and commission/incentive structure. Ingest the BSP-link weekly report at ticket granularity and match to GDS issuance with one of four outcomes (clean match, ADM debit, ACM credit, refund settlement). Tie the weekly net debit to bank statement on settlement day. Split agency commission (18 percent SAC 998551 forward charge) from tour-package revenue (5 percent or 18 percent under tour-operator option). Run ADM dispute register with airline reference, response status and 30/60/90 ageing. Chase Section 393 code 1007 TDS on airline incentives through Form 26AS by deductor airline TAN by quarter.
Ticket master keyed by ARN-ticket-number with PNR, airline code, GDS source, fare basis and per-ticket commission structure; airline master with deductor TAN, incentive scheme tier, and Section 393 code 1007 default rate; BSP weekly report ingest with ticket-level matching engine; GDS file ingest per source (Amadeus/Sabre/Galileo) with cut-off reconciliation rules; ADM/ACM register with airline-reference, error code, 30/60/90 ageing and dispute response log; GST classification table separating SAC 998551 18 percent agency commission and Notification 11/2017 5 percent tour-operator option; OTA aggregator master with Section 393 code 1010 and Section 52 CGST TCS flag; Form 26AS quarterly reconciliation by deductor airline TAN.
A weekly BSP-link to GDS reconciliation report with ticket-level match and exception breakdown; per-airline ADM/ACM ageing report with dispute response status; monthly agency-commission revenue with 18 percent GST output split from any tour-package revenue at the elected GST rate; per-airline incentive-receivable ledger with Section 393 code 1007 TDS chase; OTA-aggregator settlement reconciliation with code 1010 TDS and Section 52 CGST TCS credit; quarterly Form 26AS reconciliation by deductor TAN with chase-list for missing credits; FEMA-compliant outbound forex log for international ticket settlements where applicable.
A Delhi-headquartered IATA-accredited travel agency operating across 14 branches in metro and tier-2 cities closes May 2026 with ₹85 crore of weekly BSP throughput aggregated across four cycles, 22 participating airlines, three GDS (Amadeus dominant, Sabre and Travelport secondary), 1.84 lakh tickets issued, ₹62 lakh of ADMs raised by airlines and ₹38 lakh of incentive receivables accrued. The CFO walks five reconciliation rails concurrently: BSP-link weekly to bank statement, GDS booking files to BSP-link, ADM/ACM lifecycle with airline dispute response, refund cycle from RA filing to BSP settlement, and Section 393 code 1007 TDS chase against 22 deductor airline TANs through Form 26AS. IATA BSP airline agent reconciliation India at scale is not one reconciliation problem — it is a multi-party, multi-cycle settlement discipline where the audit trail per ticket is the single most important control.

How does the IATA BSP weekly settlement actually work?
The BSP — Billing and Settlement Plan — is the centralised airline-agent settlement system operated by IATA in over 175 countries. In India, BSP-India handles weekly settlement between IATA-accredited travel agencies and participating airlines:
- Ticket issuance — agent issues a ticket through a GDS (Amadeus, Sabre or Travelport). Each ticket carries an ARN (Airline Reporting Number) and a unique ticket number.
- Weekly cycle — Monday to Sunday transactions accumulate; the cycle closes Sunday end-of-day.
- BSP-link weekly report — IATA publishes the per-agent weekly billing report listing per-ticket sales, refunds, ADMs and ACMs per airline, with the net settlement amount.
- Bank debit — typically on the Friday following the cycle close, the agent’s authorised bank account is direct-debited for the net settlement amount. Where the agent is in net-credit position (refunds exceed sales), the bank is credited.
- Reconciliation — the agent ties the BSP-link report to the GDS issuance file and to the bank statement debit on settlement day.
Failure to honour the BSP debit triggers escalation through the IATA financial-criteria framework, with potential consequences ranging from increased financial-guarantee requirements to suspension of the agency’s IATA accreditation.
What are the five concurrent reconciliation rails?
Rail 1 — BSP-link to bank statement
The weekly net settlement amount on the BSP-link report must reconcile to the bank statement debit on settlement day. Variances are typically rounding, currency-rate-of-exchange differences on international tickets, or timing differences where the debit lands T+1.
Rail 2 — GDS booking files to BSP-link
Each GDS produces a daily issuance file keyed by PNR and ticket number. Reconciliation ties each GDS-issued ticket to the BSP-link weekly report. Recurring exception patterns:
- Void-rebook timing differences — ticket voided in GDS just before cycle close appearing in BSP because of GDS-to-BSP cut-off timing
- ADM imposition post-issuance — airline raises an ADM for fare-loading error, commission misapplication or unreported issuance after the ticket has cleared
- Refund-application timing — Refund Application (RA) filed in GDS in week 1 settles in week 2 BSP
- Currency conversion variance — international ticket priced in USD with the issued amount converted to INR at GDS rate but settled at BSP day’s rate
With 22 airlines and 3 GDS, the reconciliation is an n-by-m matrix held at ticket-number granularity.
Rail 3 — ADM and ACM lifecycle
Airline Debit Memos (ADMs) are airline-initiated debits to the agent for fare-loading errors, commission disputes, unreported issuances, or compliance breaches. Agency Credit Memos (ACMs) are the reverse — airline credits to the agent for correctable errors. The dispute register holds:
- Airline reference and ADM number
- Error description and amount
- Date raised, dispute filed, response received
- Ageing: 30/60/90 from raise date
The 30-day window to dispute an ADM at the BSP layer matters — beyond it the ADM crystallises and the amount is recovered through the agent’s settlement. Industry-typical ADM incidence is 0.3-0.8 percent of weekly billing — a 0.5 percent rate on ₹85 Cr weekly is ₹42 lakh of ADM activity to manage.
Rail 4 — Refund and RA cycle
A refund originates from a Refund Application (RA) filed in the GDS at cancellation. The refund applies the airline’s fare-rule and computes the net refund — gross fare minus penalty minus commission claw-back where applicable. The RA is queued for BSP settlement in the next available cycle. The reconciliation tracks:
- RA filed date in GDS
- Settlement cycle in which it appeared on BSP-link
- Net refund credited or commission clawed back
- End-customer refund payout from the agent’s wallet
Rail 5 — Section 393 code 1007 TDS on airline incentives
Airline incentive payments to IATA agents — productivity-linked, override commission and segment-incentive structures — fall under Section 393(1)(f) code 1007 at 2 percent (legacy 194H). The agent’s quarterly Form 26AS reconciliation by deductor airline TAN chases this credit. Incentive payments often lag the underlying BSP cycle by 30-90 days because incentive structures are slab-based and reconciled monthly or quarterly. The lagged TDS credit is a working-capital lock.
What is the GST split between 5 percent tour-operator and 18 percent agency commission?
Two distinct treatments apply concurrently:
Pure air-ticket agency on BSP rails — the agent acts as agent for the airline. Principal supply is air travel by the airline. The agent’s revenue is the commission and incentive from the airline (or the service fee charged to the customer separately). Agency commission is taxable at 18 percent under SAC 998551 (services of travel agents) under forward charge.
Tour-operator option — under Notification 11/2017 entry 23, a tour operator can elect:
- 5 percent GST on the gross tour package value (without ITC), or
- 18 percent on the value addition only (with ITC)
The election applies to packaged tour services (air + hotel + ground transport bundled). Mid-tier IATA agencies typically run both — pure air-ticket agency on BSP rails and tour-package operator on direct customer contracts — and the reconciliation must split each so it files in the correct GSTR-3B box.
