Your takeoff quantifies the duct. It has never once quantified the zip screws, the hanger strap, or the 45/5 capacitor in van three. Arda puts a scannable card on every bin you stock, on the shop shelf and in every truck, so a scan fires the reorder and the van is loaded before the crew is.
Your first 10 cards are free. Unlimited users, so every tech can scan from day one.
Trusted by manufacturers including Rossmonster, Assembly Industrial, and Fat Fender.
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 or to a van's restock cycle, so replenishment starts the moment stock runs low and the bin refills before the second one runs dry. That works the same on a box of zip screws on the fab shop shelf, a pail of duct mastic, or the run capacitors riding behind the driver's seat.
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 season or a job changes what you burn, you resize the card once. Nobody recalculates a min/max by hand.
The shelf did not fail. The signal did.
In this trade the loss event is not a stalled machine. It is a truck roll that produced nothing: the tech arrives, the van is short one part, the job aborts and the customer gets rescheduled. A single return visit runs roughly $150 to $300 in fuel, tech hours and vehicle wear, and ACCA puts a two-hour callback closer to $650 once overhead and forgone billable revenue are in the number. Parts readiness is what decides first-time fix rate more than anything else. The benchmark contractors aim at is 80% or better. Without a system for what rides in the van, 60 to 70% is typical.
A tech drives 40 minutes, diagnoses in 10, then reaches for a 45/5 capacitor that the last tech took and never called in. The call is dead. You pay for the drive, reschedule the customer, and pay for the drive again tomorrow.
The install crew loads at 6am against a shelf everyone assumed was stocked. The hanger strap is gone and there is half a box of zip screws. Now three people are standing at a will-call counter instead of hanging duct, and the whole day slides right.
Restocking is whoever remembers on a Friday. Each van drifts on its own, the shop shelf drifts separately, and the office finds out what ran out only when a tech calls in from a driveway. A system that asks somebody to tally five trucks every week will not fix it, because nobody is going to do it.
Arda's inventory replenishment software works the same in both of your stockrooms, the fab shop shelf and the back of every van. Every bin gets a scannable card. A tech scans the empty screw bin in van three before pulling away, and the reorder fires for van three, not for the building. The office sees every card and every location in one view, so the shop knows which truck is short before the tech does. No purchase order to type, no dispatch software to replace, no ERP rollout.
A takeoff quantifies the duct, the flex and the liner. It has never once quantified a box of zip screws, a roll of coiled hanger strap or a 45/5 capacitor, and those are exactly the three things that end a day. The same card works on all of it, on-BOM and off, and it works the same whether the bin sits on the fab shop shelf or behind the driver's seat.
Every stocked item gets a durable card with a QR code, on the shop shelf and in the van. A tech or a shop hand scans it with the phone already in their pocket. No scanner gun, no login friction, nothing new to learn.
The scan hits Arda's backend, which places the reorder at the right quantity from the right supplier. No purchase order to type.
The office watches which cards are pulled, on order, or restocked, per van and per shelf, without opening a single truck door.
Each card encodes a loop sized to real consumption: reorder point, the two-bin system, min/max levels, and safety stock. On a van the quantity reflects your restock cycle rather than a supplier's lead time. The math lives on the card, not in someone's head.
Card it today, scan it tomorrow, and see the reorder fire without anyone tallying a truck. Expand across the fleet and the fab shop 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 crew on day one.
No scanner gun, no new login, no training day. A tech scans with the phone already in their pocket, in the shop or in a driveway, 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, on the shelf or in the van, not buried in a back-office sheet that drifts the moment demand shifts.
One scan when a van bin runs low, and the refill is already moving. Same motion for every bin in the truck and on the shelf. No software to learn.
Orders fire at the right quantity with no stack of manual POs, and every card's status sits in one place, per van and per shelf.
Hands off reordering for good and gets the hours back for bidding, with real consumption data across every location instead of gut feel.
Shops that put a card on everything they hold, in the building and on the road, and stopped losing days to the one part that was somewhere else.
Heavy-industry fabricator of custom trucks and metalwork. Same gauge steel, same fastener and consumable burn as your fab shop. Weekly stockouts gone, and the floor went from four builds at a time to eight in six months, without a bigger shop or a bigger team.
Read the Assembly Industrial case study →
Custom vehicle shop, and they got here after two failed ERP implementations. Cards went on the parts they stock, stockouts went to zero, and the order backlog fell from 365+ days to 20. No rip and replace on the systems they already ran.
Read the Fat Fender case study →Overland vehicle builder. Holdings on critical components fell from 25+ down to 5 while output went up 6×, because the reorder signal moved onto the bin instead of onto a person.
Read the Rossmonster 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 bin in one van 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 every tech, installer and shop hand can scan from day one.
Rossmonster got cards onto 100% of its supplies inside a year, including the stock nobody had been watching. Start with the bin that killed your last call, on us, and let the van reload itself.
Free plan, unlimited users, no ERP rollout.
