I have two stores with different names and addresses. How can I use Zoho Books for both the stores? Do I need to buy two separate subscriptions?

No, it is not necessary to buy two separate subscriptions. Businesses with multiple locations can create branches and manage their accounts within Zoho Books. You can add branches to transactions and run branch-specific reports to evaluate the performance of each branch. You can create up to three branches ( three different GSTIN) if you’re using the Premium, Elite, or Ultimate plan of Zoho Books. You can also purchase GSTIN add-ons to add more branches to your organization.
