Your ERP never sees the cutting tools, inserts, and coolant your shop burns through, and it is rarely much help on the bar stock, fasteners, and fixturing either. Arda puts a scannable card on every item you stock, consumable or not, so a scan fires the reorder and the crib is full before the next setup.
Your first 10 cards are free. Works alongside your ERP, no rip and replace.

A stockout is a reorder that fired too late, or never fired at all. Count-based systems leave that trigger to a person, and people are busy. Arda makes the trigger physical: the card on the bin is the reorder, sized to your supplier's lead time, so replenishment starts the moment stock runs low and the shelf refills before the second bin runs dry. That works the same on a box of inserts, a rack of bar stock, or a bin of purchased components.
Scanning the empty bin is the fastest way to get more, so the reorder fires on its own, every time.
Reorder point and safety stock are set to your real burn rate and lead time, so the second bin always covers the wait.
When a job changes what you burn, you resize the card once. Nobody recalculates a min/max by hand.
A stockout is a signal that never fired. Arda makes the signal impossible to miss.
Machine shops run high-mix, low-volume work, so the items that stop a job, whether that is a carbide insert or a length of bar stock, are exactly the ones no system is watching closely enough.
MRP assumes someone keys in what got used. Between setups, nobody does, so the shortage only surfaces when a machinist reaches for an empty drawer.
An operator pulls inserts from a partial build to finish a hot order. The sheet never hears about it, and every borrowed part widens the gap.
The owner reorders coolant and hardware from memory between quotes. It works until the one week it does not, and a $200 box idles a $200,000 machine.
Arda's inventory replenishment software for machine shops puts a scannable card on every item you stock, starting with the consumables your ERP never sees, so the scan fires the reorder on its own. No counting, no purchase order to type, no ERP rollout. Scan a card, the material shows up.
Consumables are where the pain is loudest, because they never make it onto a BOM, so nothing is watching them. But the same card works on anything you stock, on-BOM or off. Put a card on it and the shortage disappears.
Every stocked item gets a durable card with a QR code, from a drawer of inserts to a bin of fasteners to a rack of raw material. A machinist scans it with any phone, no extra hardware, no login friction.
The scan hits Arda's backend, which places the reorder at the right quantity from the right supplier. No purchase order to type.
Purchasing and the owner watch which cards are pulled, on order, or restocked across parts and locations, without walking the floor.
Each card encodes a proven loop sized to your real consumption: reorder point, the two-bin system, min/max levels, and safety stock. The math lives on the card, not in someone's head.

Card it today, scan it tomorrow, and see the reorder fire without anyone counting. Expand across the crib when it has proven itself.
Count-everything tools fail because they add a task. Arda removes one. That is what holds compliance past week one.
The card is the replenishment signal, on every item you stock. Nobody tallies stock or runs a cycle count to make the numbers real.
The simplest way to do the job is to scan the card, so compliance sticks where badge-in ERP screens lose the floor on day one.
No scanner gun, no new login, no training day. A machinist scans with the phone already in their pocket, so nothing new stands between them and the reorder.
Reorder point, min/max, and safety stock are baked into the card at the point of use, not buried in a back-office sheet that drifts the moment demand shifts.
One scan when a bin runs low, and the refill is already moving. Same motion for every item on the floor. No software to learn.
Orders fire at the right quantity with no stack of manual POs, and every card's status is in one place.
Hands off reordering for good and gets the hours back for quoting, with real consumption data across the whole shelf instead of gut feel.
High-mix, low-volume shops that put a card on what they stock, from consumables to raw material to finished components, and got their throughput, and their time, back.
Overland vehicle builder. Cards went on 100% of supplies inside a year, and holdings on critical components fell from 25+ to 5 while output went up 6×.

Custom vehicle shop, after two failed ERP implementations. Eliminated stockouts across the parts they stock and cut the order backlog from 365+ days to 20.
Read the Fat Fender case study →For the items that actually stop a job, here is how the three common approaches stack up on the floor.
| Arda | ERP / MRP | Spreadsheet / memory | |
|---|---|---|---|
| Signal to reorder | Scan a card, order fires automatically | Manual entry, then a planning run | Someone remembers to look |
| Covers every stocked item | Yes, on-BOM and off, same card | On-BOM only, misses the rest | Only if updated by hand |
| Shop-floor compliance | High, scanning is the easy path | Low, floor skips data entry | Low, depends on one person |
| Setup time | Start with one part in a day | Months of implementation | Fast, but breaks as it grows |
| Works with your existing ERP | Yes, splices in, no rip and replace | It is the ERP | Disconnected from it |
| Cost to get started | $0 for your first 10 cards | High license and rollout cost | Free, until a stockout costs a day |
Weighing specific tools rather than whole approaches? The Arda Comparison Hub has side-by-side breakdowns against eTurns, Fishbowl, Katana, Cin7, Fastenal, Odoo, Sortly, and more.
No implementation project. Card a single item and the loop is running.
Free plan, no card required to try it. Paid plans add a 7-day trial.
Splices in alongside QuickBooks, NetSuite, Odoo, Xero and more. No rip and replace.
Priced per card, not per seat, so the whole floor can scan from day one.
Assembly Industrial rolled Arda out in days and doubled what its floor could build. Start where it hurts most, on us, and let the shelf reorder itself.
Free plan, unlimited users, no ERP rollout.
