Onsumm is built for Indian accounts payable rather than adapted from a US or EU product: GST, TDS, HSN codes, e-invoicing, Tally Prime and Zoho Books are first-class, and the approval workflows follow how Indian finance teams already sign off on a vendor bill. ## Pages - [AP Automation for Indian SMEs — Tally & Zoho Books](https://www.onsumm.ai/): AI accounts payable automation for Indian SMEs — invoice OCR, approval workflows, GST and TDS compliance, and direct Tally Prime and Zoho Books posting. - [Invoice OCR, Approval Workflows, GST & TDS](https://www.onsumm.ai/product): Invoice OCR, a multi-level approval matrix, GSTIN verification, automated TDS on vendor bills, vendor bank verification and duplicate invoice detection. - [AP Automation Pricing for Indian SMEs](https://www.onsumm.ai/pricing): AP automation for Indian SMEs from ₹4,999 a month — invoice OCR, GST and TDS validation, approval workflows, and Tally Prime and Zoho Books integration. - [Contact & Demo — AP Automation India](https://www.onsumm.ai/contact): Book a demo of Onsumm — AP automation for Indian SMEs.

Onsumm does all four on every vendor bill it processes, and holds the section rules as data rather than code so a rate change is a configuration change rather than a release. ## Contact - Email: hello@onsumm.ai - Demo: https://www.onsumm.ai/contact
