Importing Sales data from Posist to Zoho Books

Importing Sales data from Posist to Zoho Books

Hi, We use Posist as our POS. They have integration only with Tally. What do I need to import sales data from Posist into Zoho books.

We accept Cash, Credit cards, Web ordering, discounts and online partners.

Also How do I import them into zoho? Since we generate 100s of invoices everyday adding each sales manually is not an option.
