What are the limitations of Tally and Vtiger integration?

The following are the limitation of Tally and Vtiger integration:

• Product taxes will not be overwritten from Vtiger to Tally if the product updated in Vtiger is synced from Tally earlier.
• Taxes can be synced only one way - from Tally to Vtiger. Even if the Sync Direction is Vtiger to Tally, Taxes get synced only from Tally to Vtiger.
• The default Sales Order Number in Vtiger gets synced to the Voucher Number in Tally. The Tally’s Sales Order No field is redundant when syncing from Vtiger to Tally.
• If the default tax mode is Group, and Charges on taxes are present in Vtiger, then records get skipped.
