Excello Services

“Excelled People For Excellent Services”

Inventory and cost accounting software that keeps stock counts and the books in step.

Excello runs inventory and cost accounting software for you: stock quantities and item records are kept up to date, and inventory value and cost of goods sold are recorded inside your own QuickBooks, Xero or Odoo and reviewed by accountants.

Sales from Shopify, Amazon and Noon come in daily, and inventory is checked at every close, within five business days as standard.

What you hold, and what it's worth, in one set of books.

What inventory and accounting software has to keep in step

Two records

Every product business keeps two records of its stock: how many units it holds, and what those units are worth. Inventory accounting keeps the second one right.

Stock is an asset until it sells. At that moment its cost moves into cost of goods sold, which is what turns revenue into gross margin. If the two records drift, margins, tax and every stock decision drift with them.

Any software accounting for inventory handles the arithmetic. The drift comes from everything around it.

  • Marketplace settlements. Amazon and Noon pay out after fees, refunds and reserves.
  • Returns. Some go back on the shelf, some are written off, and both change the numbers.
  • Missing costs. Freight and duties left out of stock cost make margins look better than they are.
  • Several channels. The same product sold in a store, on Shopify and on Amazon.

Inventory valuation: how cost of goods sold is worked out

Costing methods

When the price you pay for stock changes, the costing method decides which cost each sale carries. That choice shapes gross margin and the value of stock left on the balance sheet.

Accounting software with inventory valuation applies one method automatically, so it is worth knowing which one yours uses before relying on its margins.

Same stock, same sales. A different costing method can still give a different margin.

Accounting software for shop inventory, compared with a managed service

Side by side

Accounting software with inventory reporting shows stock levels, values and margins. Accounting software with inventory analysis goes further into slow sellers and reorder points.

Both depend on the records underneath being right. When choosing inventory accounting software small business owners should ask who will keep those records current once the software is running.

Five habits for accurate inventory

Good stock records

  1. Record the full cost of stock

    Include freight, duties and packaging in the cost of goods you buy, so margins are real.

  2. Keep one product list across channels

    One SKU per product in every store and marketplace stops the same item being counted twice.

  3. Record returns and damaged stock promptly

    Stock that can no longer be sold should leave the books when it leaves the shelf.

  4. Count stock on a regular schedule

    Regular counts catch shrinkage while it is small, well before year-end.

  5. Reconcile marketplace settlements every month

    Fees, refunds and reserves change what you really earned on each sale.

Frequently asked questions

What is inventory accounting?

Inventory accounting records the value of the stock a business holds and moves that value into cost of goods sold as items sell. It keeps the balance sheet and the gross margin accurate for any business that sells physical products.

What is the best inventory accounting software for a small business?

For most small businesses it is the inventory features in QuickBooks, Xero or Odoo, or a stock app connected to them. Odoo suits businesses that want stock and accounting in one system, and Excello works inside all three.

Does Excello track stock quantities or just the value?

Both. Excello keeps stock quantities and item records up to date alongside inventory value and cost of goods sold, so what your systems say you hold matches what your books say it is worth.

How is cost of goods sold calculated?

As items sell, their cost moves from inventory into cost of goods sold, using your software's costing method, such as FIFO or average cost. Accountants review the result at every month-end close.

Can Excello handle Shopify and Amazon inventory?

Yes. Sales, refunds, fees and reserves from Shopify, Amazon and Noon are recorded daily, stock and cost of goods sold are updated from them, and everything is reconciled at every month-end close.

What happens after a stock count?

Any difference between counted and recorded stock is recorded as a stock adjustment. Quantities and inventory value then match what is actually on the shelves, and the change shows clearly in your books.
