The sixty-second answer
Treat paying for goods and receiving them as two separate steps. Send each purchase into a receiving queue, check what actually arrived against the bill, sort each line into stock, equipment, shipping or ignore, attach freight bills that arrive later, and shelve the goods in a known location. Only then does the purchase count as inventory.
Two events that get treated as one
In a small business the bookkeeping usually starts with money. A supplier sends a bill, someone pays it, and the receipt gets filed. The goods themselves arrive on a different day, in boxes, often while the person who paid the bill is doing something else.
If stock is recorded from the bill, the inventory count describes what you paid for, not what you have. The two differ more often than people expect. Lines get short-shipped or back-ordered. Something arrives damaged and goes back. The invoice includes a pallet charge, a fuel surcharge and a box of printer paper for the office, none of which is stock for resale.
The receiving step is where those differences get resolved. It is a small amount of work per delivery and it is the difference between a stock count that matches the shelf and one that has to be rebuilt at year end.
Why the count has to be right
This is not only about knowing what to reorder. Every business has to keep records and books of account, and for a business that carries stock that includes an annual inventory kept in the prescribed manner [1]. The regulations say what that means: the inventory has to show the quantities and nature of the property in enough detail that it can be valued [2].
A list of purchases does not meet that description on its own. It shows what was bought, not what is on hand. A receiving record that confirms what arrived, at what cost, and where it was put is much closer to what the regulation asks for, and it makes the year-end count a check rather than a reconstruction.
What a receiving queue is
A receiving queue is simply a list of purchases that are paid or billed but not yet checked in. Each purchase waits in the queue until someone deals with it. Clearing an item from the queue means four things have happened.
The lines have been sorted. Each line on the bill is either stock you will resell, equipment the business will keep and use, a shipping or duty charge, or something that is not inventory at all and stays an ordinary expense.
The quantities have been confirmed. What arrived matches the bill, or the difference has been recorded. Short-shipped lines stay open until the rest arrives or the supplier credits them.
The costs have been attached. Shipping, duty and any local handling are added to the goods they relate to, so the item carries its full landed cost.
The goods have a location. Someone has put them somewhere and recorded where, so the next person can find them.
Sorting the lines
Supplier invoices from wholesalers and general suppliers are often mixed. The same bill can contain twenty units of something you sell, a drill for the shop, a shipping charge and a case of cleaning supplies. Each belongs somewhere different.
Stock for resale goes to inventory. The drill is a business asset, not stock, and belongs in an asset register. The shipping charge is part of the cost of the stock on the same bill. The cleaning supplies are an ordinary expense. Doing this split at receiving, while the bill is in front of you and the goods are on the bench, is far easier than trying to unpick a year of mixed purchases later.
Matching the bill to what arrived
The check itself is simple: open the boxes, count, and compare to the bill. The discipline is in what you do with the differences.
A short shipment should leave the missing quantity open, not quietly receive the full amount. A damaged item that goes back to the supplier should not enter stock. A substitute product should be received as what it actually is, not as what was ordered. None of this requires a formal three-way match with purchase orders, which most small businesses do not use. It only requires that what goes on the shelf and what goes into the count are the same thing.
Freight bills that arrive on their own
The most common gap in small-business inventory is freight that arrives separately. The goods come from the supplier. The freight bill comes from the carrier or the broker, a week or two later, with a waybill number instead of a product name. It gets filed as a general shipping expense and never meets the goods it paid for.
That matters because freight is part of what the goods cost you. The inventory standard counts all costs of bringing inventory to its present location and condition as part of its cost [7]. Freight booked as a general expense leaves every item in that shipment with a cost that is too low, and the margin on those items looks better than it is.
The fix is to keep a receipt open to later costs, or to be able to reopen it, so the freight bill can be attached to the shipment when it arrives. If some of the goods have already sold by then, the freight on those units belongs to cost of goods sold for the period rather than to what is still on hand.
Freight bills also carry tax. Delivery and freight charges are among the purchases on which a registrant may be able to claim input tax credits [6], so the freight bill needs to be kept and handled as a proper receipt, not only as a number added to stock cost.
Keeping the paper trail intact
Receiving adds a step between the receipt and the inventory figure, so it has to preserve the link between them. The CRA describes an audit trail as the information needed to recreate the sequence of events for a transaction, and says electronic records must show an audit trail from supporting documents to the summarized accounts [5]. A received item should point back to the purchase it came from, and the purchase should point back to the receipt.
The receipt remains the key document on the tax side too. GST/HST records must be kept in a form that allows your obligations to be determined [3], and an input tax credit can only be claimed if, before filing, you hold evidence containing the prescribed information [4]. Receiving stock does not replace the receipt. It sits on top of it. Books and records generally have to be kept until six years after the end of the year they relate to [1].
Putting it away
The last step is the one most often skipped. Goods that have been received but not put in a known location are only slightly more useful than goods that have not arrived. In a shop with one back room this can be as simple as a shelf label. In a business with a warehouse, a van and a job site, it is the difference between selling the item and reordering it by mistake.
Recording a location at receiving time, even a rough one, is enough to make the next stock count faster and the next customer question answerable.
How often to clear the queue
Daily is ideal and weekly is workable. The risk grows with time: a queue left for a month is full of purchases whose boxes have been opened, used and thrown away, and nobody remembers what was actually in them. At that point receiving becomes guesswork, which is exactly what it was supposed to replace.
How MapleInventory handles it
MapleInventory starts from the purchases you already file. Receipts and bills entered in MapleExpense under resale or asset GIFI codes land in the MapleInventory receiving queue, so there is no second data entry step. Maple-AI sorts each line into resale stock, company asset, freight or duty, or ignore, and you confirm or correct the sort before anything is received.
Freight and duty lines are rolled into landed cost, which MapleInventory breaks into actual cost, taxes and duties, shipping, and local stocking costs, spread across the shipment by value or quantity. Recoverable GST/HST stays out of cost by default. Items sorted as company assets go to the asset register instead of stock. If you have set up racks, shelves or bins, Maple-AI suggests a put-away location for each item; otherwise you pick one. You then set the retail price, with a suggested price if you have set a target margin, and the stock is valued at weighted-average landed cost from that point on.
