Where the money goes
Most of what a small business loses is in paperwork nobody had time to check.
Bills that don't match the order.
A supplier bills more units, or a higher price, than the purchase order said. If nobody compares the two, it gets paid.
Example: $3,780 billed against a $2,070 order.
The same bill paid twice.
The invoice arrives by email and again on paper, or two people settle the same supplier. Getting the money back takes weeks.
Invoices nobody chased.
An invoice is three weeks late and nobody has written to the customer, because everyone assumed someone else had.
Keep the books you already have.
SmallERP works alongside Zoho Books, Odoo, Xero and QuickBooks. Your records stay where they are. The agents check the bills, payments and expense claims in them, and you get a card when one needs your decision.

Features
Your invoices and your stock in one system.
When you send an invoice, SmallERP takes the items out of stock, records the tax, posts the journal entry and adds the amount to what that customer owes you. Nobody enters it twice.
Inventory
Stock for every location, with an alert when an item runs low.
