Contractor Inventory: A Checklist for Usable Van Stock

A stock list is useful only if it answers the question you have before the next job: what can we actually use, where is it, and who checked? A total for the whole business can hide the fact that the part is in another van, reserved for a different job, or waiting for a delivery that has not arrived.

Start with a small inventory record you can keep current. This guide provides a stock-card checklist, a worked example and a routine for movements and counts. The examples are hypothetical. They do not establish a required stock level, a savings estimate, or a promise that you will never run short.

Choose what belongs in the stock record

Separate materials you use up from equipment you expect to get back. A box of identical parts needs a quantity and location. A particular drill may need an individual identifier and a record of who has it. Trying to describe both with a single quantity field makes it difficult to distinguish material use from a tool that moved to another crew.

Start with items that regularly cause a question: frequently used parts, items shared between vans, or materials that are difficult to replace at short notice. You do not need to enter the entire supplier catalogue before you can make the first useful record. Keep special-order materials tied to the intended project so they are not casually treated as general stock.

This checklist concerns inventory records. It does not specify which electrical, plumbing or other technical parts are suitable for a job, how to store hazardous materials, or how inventory should be valued for tax or accounting. Use the appropriate manufacturer instructions, project requirements and qualified advice for those decisions.

Give each item a clear unit and location

Write a description that someone else can use to distinguish the item from a similar one. Include the relevant item code, size or variant. Decide what a quantity of one means. An unopened box, an individual piece and a length of material are different units; changing between them without recording the conversion creates a count that looks precise but means little.

For a hypothetical item supplied in boxes of 20, three full boxes represent 60 individual pieces. If you issue individual pieces, keep the stock record in that unit or record the conversion explicitly. Do not apply that pack size to a different supplier or package without checking it. For partially used lengths, distinguish a measured quantity from an estimate and use an appropriate counting method for the material.

Name the place where the stock is held: for example, Shop Shelf B, Van 2 Bin C, or the designated area for a particular job. A bin label and the record should use the same name. Avoid a vague location such as “with the crew” when more than one crew could have it.

Record usable stock, not just a physical total

Keep a short stock card with the item and unit, location, counted quantity, any reservation or hold, outstanding delivery reference, and the date and person responsible for the last check. A note should explain an exception instead of silently changing the meaning of the quantity.

Inventory systems use different words for the same idea: what is physically there versus what you can actually use. Pocket Boss tracks stock per location, so parts on the truck and parts in the shop are separate counts, with low-stock alerts and purchase orders for what is still on the way. Whatever tool you use, decide which quantity your team means when someone says "we have four".

Consider this original hypothetical count of one generic item in Van 2. The four reserved units and two damaged units are separate groups; none of the damaged units is also included in the reservation.

Six available units are not a recommendation to use the last six or a guarantee that the item suits a new job. Check the actual requirement and any stock you need to retain. If the record already subtracts reservations, do not subtract them again in a separate worksheet.

Close the record when stock changes location

A move from the shop to a van is different from buying more material or consuming it on a job. Record the item, quantity, unit, starting location, destination and a reference for the move. The person receiving it should confirm what actually arrived. A transfer marked as sent should not be mistaken for a confirmed quantity at the destination.

Here is a separate hypothetical transfer. The shop has 20 units and Van 2 has five. Move three units from the shop to the van. After all three are received, the records should show 17 at the shop and eight in the van: 17 + 8 = 25, the same physical total as before the move.

If the receiver finds only two, investigate the missing unit and record the unresolved difference. Do not enter eight simply to match the sending note or claim the missing unit is usable stock. Check whether it stayed on the shelf, went to another location, or was recorded with the wrong unit before deciding how to correct the record.

Distinguish job use, returns and tool custody

Record materials used against the relevant job or work reference at a point in the work you can maintain. A van restock record alone does not explain which job used the material. Conversely, copying a planned material list into actual usage can overstate what was consumed.

When unused material comes back, check its identity, quantity and condition before adding it to available stock. Keep a return with an unresolved condition or ownership question separate until the responsible person decides what happens next. For a reusable tool, update its location or custody record instead of treating the movement as consumption.

Keep the quantity record distinct from what you charge a customer. Stock leaving a van does not by itself establish that it is billable. Your contractor estimate describes proposed work and quantities; the actual job record should explain what changed. The broader contractor project-management guide covers coordinating that work with the rest of the job.

Receive what arrived, not what was ordered

Compare the delivery with the order and the physical items. Record the quantity received, the unit and where it was placed. Note shortages, substitutions or items held for checking. If you ordered ten and received eight, the record should not claim that all ten are ready for use.

Keep the outstanding quantity visible with its order reference and the next person responsible for checking it. An expected date is useful planning information, but it is not a receipt. A direct delivery to a job should be recorded at that job's location rather than appearing to have arrived at the shop.

Use a small count to find the reason for a difference

A full count is not the only time you can compare records with physical stock. A cycle count checks one shelf, bin or van section at a time, which is easier to fit between jobs than a full shutdown count. In Pocket Boss each location keeps its own quantities, so you can count one truck and adjust only that location.

Choose a shelf, bin or van section and note the count time. Avoid moving stock through that area during the count, or record the movements so they can be reconciled. Confirm the item and unit, count it, and compare the result with the record for that same point in time.

Before changing a quantity, look for an unrecorded transfer, an open delivery, recent usage, a return, a unit mismatch or a duplicate entry. Recount if necessary. Save the correction with a reason and the person making it. An unexplained shortage is a discrepancy to investigate, not proof that someone stole the item.

Review restocking against actual work and deliveries

Choose a review routine that suits the items and how they move. Check sooner when a large job changes the plan or a supplier reports a delay. A printed minimum can become outdated; it should prompt a decision rather than replace one.

Before ordering, check available stock in the relevant location, reservations, confirmed upcoming needs, open orders and their arrival timing. Decide whether stock already held elsewhere can be transferred appropriately. Record who will order, follow up or defer, and why. Avoid creating a second order because the first one is difficult to find.

There is no single stock quantity, ABC percentage or count frequency that this article can prescribe for every contractor. Use your own usage and delivery records to review the plan. Do not treat a simple average as a guarantee that changing demand or supplier delays cannot cause a shortage.

Test the record before expanding the system

A paper stock card, shared spreadsheet or suitable inventory system can be a starting point if the person making a change knows where to record it. Choose one authoritative record for each quantity and define who resolves conflicting entries. A barcode may help identify an item; it does not verify that the quantity, location or condition entered is correct.

If you are evaluating contractor inventory management software, test the actual product against your workflow. Can you distinguish units and locations, confirm a transfer, keep an unresolved receipt visible, and explain a correction? If offline use matters, test disconnection, reconnection and conflicting changes with harmless sample data before relying on it. Do not assume these capabilities from a marketing headline; this guide does not claim PocketBoss performs each step automatically.

Begin with one location and a small set of stock. Make the opening count, record a receipt, record a move and a job use, then count again. Review any difference before adding more items. The aim is a record another person can check and act on, including when the answer is that a quantity is still uncertain.
