Parts & Inventory
Parts are what you stock. Inventory is where those parts are and how many you have. This guide covers building the catalog, recording stock movements, reading your levels by location, and the tire specifications RoadBays uses to size a tire correctly.
About This Guide
This guide covers Parts and Inventory in RoadBays — setting up the parts you stock, recording what comes in and goes out, and reading your stock levels. It is written for the people who do this work day to day: parts managers, shop managers, and anyone who counts a shelf.
You do not need to read it end to end. Use the table of contents to jump to the screen you are on.
How to read the instructions
| Term | Meaning |
|---|---|
| Bold text | The exact name of a button, tab, field, or menu item as it appears on screen. Example: click Save Transaction. |
| Numbered steps | Do these in order. Each step is one action. |
| Note | Background information that helps the step make sense. |
| Tip | A faster or better way to do something. |
| Important | Something that will cause a problem if you skip it. |
Parts and inventory are two different things
Keeping these straight makes everything else easier.
| Concept | What it is |
|---|---|
| Part | The catalog record for a thing you stock — its number, name, manufacturer, cost, and reorder point. One part record, however many you have on the shelf. Created once and edited rarely. |
| Inventory transaction | One movement of stock — ten filters received, two issued to a work order, a count correction. Every transaction is kept, so the quantity on hand is the sum of everything that ever happened to that part. |
| Inventory location | A shop or warehouse where stock lives. The same part can be stocked at several locations, each with its own quantity and reorder point. |
| Bin | A specific shelf or slot inside a location. Bins are optional, but they turn "we have four somewhere" into "they are in rack C, bin 12". |
The three screens
| Screen | What it is for |
|---|---|
| Parts | The catalog. Every part you stock, with live quantities, stock status, and value. Start here. |
| Inventory Transactions | The log. Every movement in and out, newest first, with who did it and why. |
| Inventory Summary | The levels. What you have on hand, globally and by location, with low stock called out and an export for anyone who wants it in a spreadsheet. |
The Parts List
The Parts screen is the catalog and the dashboard at the same time. It shows what you stock, how much of it you have, what it is worth, and what needs ordering.
The numbers across the top
Four tiles summarize whatever you are currently looking at. Switch location tabs and all four recalculate for that location.
| Tile | What it counts |
|---|---|
| Total Quantity | Every unit of every part on hand. |
| Out of Stock | How many part records have nothing on hand. Shown in red. |
| Low Stock | How many parts have fallen to or below their reorder point. Shown in orange. |
| Total Inventory Value | Quantity times unit cost, across everything on hand. This is the number your accountant asks for. |
Filtering by location
A row of tabs sits above the table: All, then one tab per inventory location. Click a location to see only that location's stock. The tiles, the table, and the status badges all follow.
Reading the table
| Column | What it shows |
|---|---|
| Part # | Your part number. The table sorts by this by default. |
| Name | What the part is. |
| Manufacturer | Who makes it. |
| Unit | The unit of measure — each, box, gallon, foot. |
| Bin(s) | Where it sits. Several bins are listed together when the part is stocked in more than one. |
| Qty | How many are on hand for the selected location, or everywhere when All is selected. |
| Reorder Pt | The level at which the part counts as low. |
| Unit Cost | What you pay for one. |
| Total Value | Quantity times unit cost. |
| Status | OK, LOW STOCK, or OUT OF STOCK. |
| Actions | View opens the part record. |
Stock status at a glance
Status is shown as a badge and reinforced by the row color, so a shelf that needs attention is visible without reading a single number.
| Status | What it means |
|---|---|
| OK (green) | On hand and above the reorder point. |
| LOW STOCK (amber, amber row) | At or below the reorder point. Order before you run out. |
| OUT OF STOCK (red, red row) | Nothing on hand. The next job that needs this part stops. |
Searching and paging
- Use the search box above the table to filter by part number, name, manufacturer, or bin.
- Click any column heading to sort by it. Click again to reverse.
- Change how many rows show per page with the length dropdown. The default is 25.
Adding parts
- Click + Add New Part to create one by hand.
- Click Import Parts to bring in many at once from a file — the right choice when you are setting RoadBays up for the first time.
Creating and Editing a Part
A part record is created once and then mostly left alone. Getting it right at the start is what makes everything downstream — pricing, reordering, reporting — work properly.
Creating a part
- On the Parts screen, click + Add New Part.
- Fill in the Overview fields.
- If the part is a tire, tick Is Tire and complete the tire specifications that appear.
- Click Save.
The Overview fields
| Field | What to enter |
|---|---|
| Name | What the part is, in words a person would use. "Oil filter, C15" beats "FILT-ASSY-LUBE". |
| Part Number | Your part number. This is what people search on, so use the number your team actually says out loud. |
| Manufacturer | Who makes it. Useful for filtering and for finding an equivalent when your usual supplier is out. |
| Unit of Measure | How you count it — each, box, case, gallon, foot. Get this right or your quantities will not mean what you think. |
| Cost | What you pay for one. Drives Total Value and your inventory valuation. |
| Retail Price | What you charge for one. Drives the price that fills in when the part is added to an estimate or a work order. |
| Reorder Point | The level at which the part shows as LOW STOCK. Set it to cover how long your supplier takes plus how fast you use the part. |
| Minimum Required | The floor you never want to go below — your safety stock. |
| Track By Serial | Tick for parts with individual serial numbers. Turns on serial capture when stock is received or issued. |
| Is Tire | Tick for tires. Reveals the tire specification section below. |
| Description | Anything else worth knowing — what it fits, what it supersedes, which unit it is for. |
Reorder Point and Minimum Required
These two do different jobs and are easy to confuse.
| Field | The question it answers |
|---|---|
| Reorder Point | "When should I order more?" Set it high enough that new stock arrives before you run out. If a supplier takes a week and you use two a week, two is too low — set four. |
| Minimum Required | "What must I never drop below?" Your safety net for the job that turns up unannounced. |
Tracking by serial
Tick Track By Serial for parts where each individual item has to be identified — components under warranty, anything with a manufacturer serial you may need to quote later.
With this on, the Serial Numbers box on an inventory transaction becomes the place you record which specific items moved. Leave it off and RoadBays just counts.
Tire Parts
Tires get their own set of fields, because a tire is not fully described by a part number. Tick Is Tire on the Overview tab and the tire specification section appears.
Size
As you fill these in, a live preview of the finished tire size builds up next to the section heading, so you can check it against the sidewall in front of you.
| Field | What to enter |
|---|---|
| Tire Metric/Type | P for passenger, LT for light truck, ST for special trailer, T for temporary. |
| Tire Width (mm) | Section width in millimeters — the first number on the sidewall. |
| Aspect Ratio (%) | Sidewall height as a percentage of width — the number after the slash. |
| Construction | R for radial, D for diagonal or bias, B for belted. |
| Rim Diameter (in) | The wheel diameter in inches. Accepts half sizes. |
| Load Index | The numeric load index from the sidewall. |
| Load Rating (lbs) | What that index means in pounds. |
| Speed Rating | The letter speed rating from the sidewall. |
A tire marked LT 295/75 R 22.5 146 L reads as: light truck, 295 mm wide, sidewall 75% of that, radial construction, 22.5 inch rim, load index 146, speed rating L.
Speed rating and miles per hour
Pick a Speed Rating and RoadBays fills in Speed Rating (mph) for you. The value stays editable if you need to override it.
| Rating | Max speed (mph) | Rating | Max speed (mph) |
|---|---|---|---|
| L | 75 | U | 124 |
| M | 81 | H | 130 |
| N | 87 | V | 149 |
| P | 93 | W | 168 |
| Q | 99 | Y | 186 |
| R | 106 | Z | 149 |
| S | 112 | ||
| T | 118 |
Tread and life
| Field | What to enter |
|---|---|
| Factory Tread Depth (32nds) | Tread depth on a new tire, in 32nds of an inch. The baseline every later reading is measured against. |
| Minimum Tread Depth (32nds) | The depth at which this tire must come off. Set it to your policy or the legal limit, whichever is stricter. |
| Life Expectancy (miles) | How many miles you expect to get. Feeds cost-per-mile and lets you compare one brand against another on evidence rather than opinion. |
Stock by Location
The Stock by Location tab on a part shows one panel per inventory location, so you can see at a glance where this part is and whether any location needs topping up.
| Figure | What it means |
|---|---|
| Current Qty | What is on the shelf at this location right now. |
| Avg Unit Cost | What you have actually been paying, averaged across receipts at this location. Compare it against the Cost on the Overview tab — a gap means your catalog cost is stale. |
| Reorder Point | The reorder level for this location. |
| Pending PO Qty | How many are on order and not yet received. Check this before ordering more — it is the difference between topping up and double-ordering. |
| WO Current Qty | How many are committed to open work orders. These are on the shelf but already spoken for. |
Part History
Three views answer the question "what has happened to this part?" from three different angles.
Inventory Activity
Every stock movement for this part, newest first.
| Column | What it shows |
|---|---|
| Date | When the movement was recorded. |
| Location | Which shop or warehouse. |
| Bin | Which bin, where one was recorded. |
| Type | Added, Removed, or an adjustment. |
| Qty | How many moved. Additions carry a plus sign. |
| Action | What caused the movement. |
| Reference | The document behind it — a purchase order, a work order. |
| User | Who recorded it. |
| Notes | Whatever they wrote at the time. |
Work Order Activity
Every billing document this part has appeared on — what you charged, on which job, for which customer.
| Column | What it shows |
|---|---|
| Document # | The estimate, work order, or invoice number. |
| Type | Which of the three it is. |
| Case # | The case the document belongs to, where there is one. |
| Date | When the document was created. |
| Status | Open or Closed. |
| Location | Which location the part came from. |
| Qty | How many were used. |
| Rate | What you charged for one. |
| Total | Quantity times rate. |
| Description | The line description on the document. |
Purchase History
At the bottom of the Overview tab, a chart plots what you have paid per unit over time, with the receipts listed underneath: date received, vendor, PO number, location, quantity, and unit cost.
A line trending up is a conversation to have with your supplier. A line that jumps between vendors shows which one is actually cheaper once you look at more than one order.
Inventory Transactions
The Inventory Transactions screen is the complete log of stock movement across every part and every location — changes, adjustments, and transfers, newest first.
Reading the log
| Column | What it shows |
|---|---|
| Date | When the transaction was recorded, in your local time. |
| Part | The part name with its part number underneath. |
| Location | Where the movement happened. |
| Type | The action, color-coded: green for Added, red for Removed, amber for adjustments and transfers. |
| Qty | How many moved. Additions carry a plus sign. |
| User | Who recorded it. |
| Notes | Shortened to fit — hover to read the whole note. |
| Actions | Edit or Delete the transaction. |
Use Search activity to filter, and click any column heading to sort. The default is 25 rows per page, newest first.
Editing and deleting
- Edit reopens the transaction so you can correct it.
- Delete removes it, after a confirmation.
Recording a Transaction
This is the form you will use most — every time stock arrives, leaves, or turns out not to be what the system thought.
Adding a transaction
- On the Inventory Transactions screen, click + Add Transaction.
- Under Part Name / Number, search for the part. You can search by either name or number.
- Choose the Action — what is happening to the stock.
- Enter the Quantity as a positive number. The action decides whether it adds or subtracts.
- Check the Transaction Date. It defaults to now; change it if you are recording something that happened earlier.
- Choose the Primary Location.
- Choose the Specific BIN if you use bins. The bin list loads once you pick a location.
- For serial-tracked parts, enter the Serial Numbers.
- Write an Administrative Note explaining the movement.
- Click Save Transaction.
The fields
| Field | What to enter |
|---|---|
| Part Name / Number | The part. The dropdown searches both the name and the number, so either works. |
| Action | What is happening: Added when stock arrives, Removed when it leaves, or an adjustment or transfer type. This determines the direction of the movement. |
| Quantity | How many, as a positive number. |
| Transaction Date | When it actually happened. Defaults to now. Backdate it when you are catching up on paperwork, so your history stays true. |
| Primary Location | Which shop or warehouse. |
| Specific BIN | Which bin inside that location. The list loads after you choose a location. |
| Serial Numbers | One per line, or comma-separated. Only needed for parts marked Track By Serial. |
| Administrative Notes | Why. A purchase order number, a count correction reason, who authorized it. |
Bins
The bin list is empty until you choose a location, then loads the bins configured for it. If the bin you want is missing, it has not been set up for that location yet — speak to your RoadBays administrator.
Importing transactions
Click Import on the Inventory Transactions screen to load many movements at once from a file. This is the right tool for an opening balance when you first set RoadBays up, or for a full physical count.
Inventory Summary
The Inventory Summary is the stock-level view — what you have, where, without the movement detail. It is the screen to open when someone asks "do we have any?"
The three tabs
| Tab | What it shows |
|---|---|
| All Stock | One row per part, with the global total across every location. Use this to answer "do we have any, anywhere?" |
| Low Stock | Only the location rows that are running down. Your ordering list. |
| By Location | One row per part per location, so you can see how stock is spread and whether one yard is holding everything. |
The columns
| Column | What it shows |
|---|---|
| Part Detail | The part name, with a colored dot: green for healthy, red for low. |
| SKU / Part Number | Your part number. |
| Warehouse Location | Which location the row is for. On the All Stock tab this reads Total (Global). |
| Qty on Hand | How many. |
Rows that are running low are shaded pale yellow as well as carrying the red dot, so they stand out when you are scanning quickly.
Exporting
The buttons in the top right export what you are currently looking at:
- CSV — for importing into another system.
- Excel — for anyone who wants to work on the numbers in a spreadsheet.
Common Workflows
Setting up a part for the first time
- Parts → + Add New Part.
- Fill in name, part number, manufacturer, and unit of measure.
- Enter Cost and Retail Price.
- Set the Reorder Point and Minimum Required.
- Tick Track By Serial or Is Tire if either applies, and complete the tire specifications.
- Save.
- Go to Inventory Transactions → + Add Transaction and record what you currently have on the shelf as an Added transaction, with a note saying it is the opening balance.
Receiving a shipment
- Check what arrived against the packing slip before you touch RoadBays.
- Inventory Transactions → + Add Transaction.
- Choose the part, set the Action to Added, and enter the quantity that actually arrived — not the quantity on the order.
- Set the location and the bin it is going into.
- Record serial numbers for serial-tracked parts.
- Note the purchase order number.
- Save, and repeat for each part on the shipment.
Running a physical count
- Open Inventory Summary and switch to By Location.
- Export to Excel and print it.
- Count the shelves and write the real numbers on the sheet.
- For each part that does not match, add an adjustment transaction for the difference, with a note explaining it.
- Re-check the summary. It should now match the shelf.
Moving stock between locations
- Record the stock leaving the source location.
- Record it arriving at the destination location.
- Use the same reference in both notes — "transfer to Yard 2, 03/14" — so the pair can be matched later.
Working out what to order
- Open Parts and select the location tab you are ordering for.
- Read the Out of Stock and Low Stock tiles.
- Sort the table by Status to bring those parts to the top.
- For each one, open the part and check Stock by Location — specifically Pending PO Qty, so you do not order something already on its way.
- Also check WO Current Qty, since stock committed to open work orders is not really available.
- Place the order, then record the receipt as an Added transaction when it arrives.
Troubleshooting
| What you see | What to do |
|---|---|
| The quantity is wrong | Open the part and read the Inventory Activity tab from the last good count forward. Correct it with an adjustment transaction and a note — do not delete history. |
| A part never shows as LOW STOCK | It has no reorder point. Open the part and set one; without it the part jumps straight from OK to OUT OF STOCK. |
| The Parts screen and Inventory Summary disagree about low stock | They use different rules. The Summary's Low Stock tab uses a fixed threshold of five or fewer; the Parts screen uses each part's reorder point. Trust the Parts screen for ordering. |
| The bin dropdown is empty | No location is selected, or that location has no bins configured. Pick a location first; if it is still empty, ask your administrator to set the bins up. |
| The tabs on a new part are greyed out | The part has not been saved yet. Fill in the Overview and click Save — history tabs need a saved record to attach to. |
| The tire fields are not showing | Is Tire is not ticked. Tick it on the Overview tab and the section appears. |
| Speed Rating (mph) filled in on its own | That is intended — it comes from the Speed Rating letter you chose. Type over it if you need a different value. |
| We have stock but the job says there is none | Check WO Current Qty on Stock by Location. Stock committed to open work orders is on the shelf but already allocated. |
| We ordered a part we already had coming | Check Pending PO Qty on Stock by Location before ordering. It shows what is on order and not yet received. |
| Average unit cost does not match the Cost field | Avg Unit Cost is what you have actually paid; Cost is what the catalog says. A gap means the catalog is stale — update it, and check your retail price still leaves the margin you expect. |
| I cannot find a part in the transaction form | The dropdown searches name and number. If nothing comes back, the part has not been created yet — add it on the Parts screen first. |
