How to choose a Thomson Reuters ONESOURCE alternative
- Separate individual filing apps from practitioner suites. A CA firm needs bulk import, staff roles and audit reports; an individual needs a guided flow and a fixed fee.
- Check how quickly the vendor ships updates after Budget changes and portal schema updates — delays here cost filing deadlines.
- For TDS, confirm challan matching and correction-statement support; that is where most manual time goes.
