Systems that talk to each other without a person in the middle
Most companies run several systems, and someone in the middle retypes data between them. We connect them instead: Tally two-way sync, bank payment files and reconciliation, payment gateways, Amazon and Flipkart orders, Unicommerce, Microsoft Entra ID single sign-on with group-to-role mapping, Samsung Knox EMM device data, biometric attendance, lab machines and WhatsApp. We also publish APIs for partners who need your data.

IndustriesFAQ
Yes. Where Tally stays for statutory accounts, we sync invoices and receipts to it so both agree.
No. Most of our integrations have ERPNext on one side, but we also connect custom platforms, portals and mobile apps to banks, identity providers and device managers.
