1.The Integration Problem
Every GST reconciliation starts with the same tedious steps: open Tally or Zoho, export the Purchase Register, clean up the Excel/CSV, download GSTR-2B from the portal, and then begin the matching process. This manual data pipeline is the #1 bottleneck — it takes 30-60 minutes before any actual reconciliation begins.
Seamless integration between your accounting software and reconciliation tool eliminates this entirely. The goal: one-click (or zero-click) data flow from Tally/Zoho to ReconGST.
2.Tally Prime Integration: XML Export
How It Works
- 1Open Tally Prime and navigate to the company you want to export.
- 2Go to Gateway of Tally → Export → Purchase Register.
- 3Select the export format as XML (Tally's native structured format).
- 4Choose the date range (typically last month for monthly reconciliation).
- 5Save the XML file and upload it to ReconGST.
- 6ReconGST automatically parses the Tally XML, extracting invoice number, date, GSTIN, taxable value, and tax components.
Tally XML Structure
Tally's XML export contains rich structured data including GSTIN, party name, voucher number, date, HSN code, tax rate, CGST, SGST, IGST, and cess amounts. ReconGST's parser handles the complete Tally schema, including:
- •Purchase vouchers (standard and compound entries)
- •Credit notes and debit notes
- •Journal entries with GST components
- •Multi-HSN invoices with line-item breakdowns
- •Reverse charge transactions (RCM)
Advanced: Tally Local Agent (Coming Soon)
For CAs managing 20+ GSTINs in Tally, ReconGST is developing a lightweight desktop agent that runs alongside Tally Prime. The agent monitors the Tally data folder and automatically exports Purchase Register data when GSTR-2B drops on the 14th — enabling fully automated, zero-click reconciliation.
3.Zoho Books Integration: REST API
How It Works
- 1Connect your Zoho Books account to ReconGST via OAuth 2.0 authorization.
- 2Select the organization and GSTIN to sync.
- 3Configure sync frequency: manual, daily, or event-triggered.
- 4ReconGST calls the Zoho Books API to pull purchase transactions for the selected period.
- 5Data is normalized and ready for reconciliation in under 30 seconds.
Zoho API Endpoints Used
| Endpoint | Purpose | Data Extracted |
|---|---|---|
| GET /bills | Fetch purchase bills | Vendor name, GSTIN, invoice #, date, amounts |
| GET /bills/{id}/lineitems | Line-item details | HSN, tax rate, CGST, SGST, IGST |
| GET /creditnotes | Credit notes received | Adjustments and returns |
| GET /contacts | Vendor master data | Vendor name, GSTIN, phone, email |
| GET /gst/reports | GST-specific reports | Pre-computed GST summaries |
Webhook-Based Real-Time Sync
Zoho Books supports webhooks that fire when a new bill is created or updated. ReconGST can listen to these webhooks and maintain a live Purchase Register mirror — when the 14th arrives and GSTR-2B drops, reconciliation can run instantly without any data export step.
4.Comparison: Tally vs Zoho Integration
| Factor | Tally XML | Zoho API |
|---|---|---|
| Setup Time | 5 minutes (export + upload) | 10 minutes (one-time OAuth) |
| Automation | Manual export each time | Fully automated via API/webhook |
| Data Freshness | As of export time | Real-time (with webhooks) |
| Multi-Company | Export per company | Switch via API organization ID |
| Offline Support | ✅ Works offline | ❌ Requires internet |
| Error Handling | File validation on upload | API error responses with retry |
| ReconGST Support | ✅ Full support | ✅ Full support |
5.The End-to-End Workflow
Here is the complete workflow when Tally or Zoho is integrated with ReconGST:
- 1Accounting Data Sync: Tally XML upload or Zoho API auto-pull.
- 2GSTR-2B Download: Manual upload or GSP-based auto-fetch (coming soon).
- 3AI Reconciliation: ReconGST matches PR vs 2B with fuzzy matching.
- 4Review Dashboard: CA reviews matches, approves fuzzy matches, flags issues.
- 5Vendor Nudge: Bulk WhatsApp/Email follow-up for missing invoices via Nudge Hub.
- 6GSTR-3B Filing: Claim accurate ITC based on reconciled data.
- 7Vendor Vault Update: Verified vendor contact info saved for future use.
6.Security & Data Handling
- •All data transmitted via TLS 1.3 encryption.
- •PII is scrubbed before any data reaches AI models for processing.
- •Uploaded data is retained for only 48 hours, then auto-deleted.
- •Zoho OAuth tokens are stored encrypted and can be revoked anytime.
- •Tally XML files are processed in memory and never stored raw on disk.
Conclusion
The gap between accounting software and GST reconciliation is the biggest time-waster in a CA's monthly workflow. By integrating Tally or Zoho with ReconGST, you eliminate 30-60 minutes of manual data wrangling every month per GSTIN. For a practice managing 20 GSTINs, that's 10-20 hours saved every month — time you can spend on advisory work instead of VLOOKUP.
