Add Inventory Tracking, Reordering, Cost & Wholesale Pricing Inputs.
Hope you are doing good!
Since Zoho Invoice revolves around the sales spectrum of your business, the purchase cycle and thereby managing the inventory is not possible in Zoho Invoice directly.
However, you can use Zoho Books for this. It’s an accounting tool and a super-set of Zoho Invoice. Zoho Books has everything that Zoho Invoice has; In addition, you can track your inventory and set up reorder notifications when your stock reaches a set value.
To upgrade your organization from Invoice to Books (so that all your data gets transferred to Zoho Books), please refer this link:
