Inventory app for accountants and bookkeepers: run or check client stocktakes with a phone

By mise · Updated November 10, 2026

Quick answer: an accountant or bookkeeper can use an app that scans barcodes with the phone camera to count or check each client's stock. Every client is a separate store in the account, the mise AI returns each product classified (name, brand, group, category, unit, weight) and the count exports to Excel and PDF for the year-end close. Tax and reporting rules depend on the country and the client's structure, so confirm them with the accountant in charge.

Every year-end the same email arrives: a client sends a stock spreadsheet typed in a hurry, with the same product named three ways, no units and no cost. The count belongs to the client, but the closing balance sheet lands on the desk of whoever prepares the accounts.

Why client stock ends up on the accountant's desk

Closing stock feeds the balance sheet and the cost of goods sold. If the count comes out low, cost of sales rises and apparent profit falls; if it comes out high, the opposite happens. That is why the person preparing the accounts needs a figure with a clear cut-off date and a list of items behind it, not a loose total.

What has to be reported, and how, depends on the country and the type of business. Some clients only need a year-end figure for the accounts, others need a valuation schedule for an inspector or lender, and some need physical-count evidence for an audit. Confirm with the accountant in charge what applies to each client before you set the scope. For the general method, see the guide to the physical inventory count.

What the practice needs from a count

Data point	What it is for	Where it comes from in mise
Barcode and description	Identify the item without duplicates	Camera scan; the AI finds the product
Brand, group, category	Subtotals by product family	Product returned already classified
Unit and weight	Quantity in the right unit	Returned by the AI; editable
Quantity counted	Physical stock at the count date	Counted by area, with invited team members
Unit cost	Valuing the stock	Purchase invoices read (XML, PDF or photo)
Date and counter	Audit trail	Recorded on each count

The valuation method (average cost, FIFO or another method allowed where your client operates) is an accounting decision, not the app's. What mise does is bring in the costs from the invoices it reads, so you can apply your method.

Step by step: a year-end stocktake with a phone

Agree the cut-off date and time with the client. Anything received or sold after it is noted separately.
Create a store for the client in your account. Products, counts and reports stay separate from your other clients.
Read the purchase invoices (XML, PDF or photo) to load products and costs before counting.
Split by area (stockroom, shop floor, chiller, back store) and invite the client's team. Each person counts one area on their own phone, in the same store.
Count with the camera: the product comes up complete, and anything without a barcode is entered by hand. It works offline and syncs later.
Compare two counts of the highest-value areas. The differences screen shows what to recount.
Export to Excel or PDF and take it to the closing workpaper and the reconciliation to the ledger.

Worked example: physical against the books

Illustrative example. A café-bar shows stock of $31,200 in the books. The year-end count came out as:

Dry store: $11,400
Chiller: $4,850
Bar: $9,300
Freezer: $3,150
Packaging: $1,300

Counted total: 11,400 + 4,850 + 9,300 + 3,150 + 1,300 = $30,000. Variance to the ledger: 30,000 − 31,200 = − $1,200, or 3.8% (1,200 ÷ 31,200). The same arithmetic works in pounds or euros. A by-product report shows whether the shortfall is concentrated in a few items (a cost keyed wrongly, an invoice entered twice) or spread across many (waste and breakage).

That detail lets the client accept an adjustment. Without it, the variance becomes an argument.

Run it, check it, or just receive it

Run it: your practice visits, counts with the client's team and delivers the report. It can be billed as a separate service; see how much to charge for a stocktake.
Check it: the client counts and you test a sample. Ask for the 20 highest-value lines and recount them in front of the owner; if they agree, confidence in the rest goes up.
Receive it: the client counts with their own mise account and sends you the Excel file. Agree the column layout in advance so you do not rebuild the sheet every year.

Mind the scope: existence and valuation of the stock remain the client's responsibility. Put in writing what the practice does (counting, sample checks, tidying the report) and what it does not (guaranteeing nothing left the building after the count).

Offering it to your client list

Many practices include the check in the monthly fee and bill the on-site count separately. Setting the year-end count as a package with a date in November stops every client asking for help in the last week. The guide to the inventory service business explains how to package it as a service.

If you plan to use mise across several clients, the standard account serves your own business; serving other companies involves professional-use terms, which are set up on WhatsApp (see that guide). You can try the app with a free trial, no card. To see what the AI returns for a single product, try the barcode lookup.

Frequently asked questions

Should the accountant do the client's stocktake?

Usually the stock count is the client's responsibility, but many practices offer counting or checking as an extra. Who does what depends on the engagement terms and the client's structure; confirm with the accountant in charge.

Can a phone replace a handheld scanner?

Yes. The camera reads the barcode and mise returns the product classified with name, brand, group, category, unit and weight, with no setup. Items without a barcode are entered by hand.

Does mise value the stock?

It reads invoices (XML, PDF or photo) to bring in item costs and shows the value of the count. The valuation method is an accounting decision for you to define.

Can I keep each client separate?

Yes. Each client is a separate store in the account, with its own products, counts and reports. Serving other companies involves professional-use terms; see the inventory service business guide.

Does it work without internet at the client's site?

Yes. Counting works offline and syncs when the phone is back online.

Is a stocktake the same as an inventory count?

Yes, it is the same job under two names. British, Australian and Irish businesses say stocktake; US businesses say inventory count.
