Inventory Replenishment / Machine Shops

Arda's inventory replenishment software for machine shops

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.

Trusted by manufacturers including Rossmonster, Austere, and Fat Fender.

Never stock out on anything your shop holds

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.

The trigger can't be skipped

Scanning the empty bin is the fastest way to get more, so the reorder fires on its own, every time.

The buffer is sized, not guessed

Reorder point and safety stock are set to your real burn rate and lead time, so the second bin always covers the wait.

It holds as demand shifts

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.

Your tool crib runs dry mid-job, and no ERP saw it coming

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.

01

Your ERP asks the floor to count

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.

02

Spreadsheets drift when someone borrows

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.

03

Reorder-by-memory loses eventually

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.

How does inventory replenishment work in a machine shop using Arda?

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.

Built for everything a machine shop holds, not just what it burns through

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.

Scan the card when a bin runs low

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.

2

The order fires automatically

The scan hits Arda's backend, which places the reorder at the right quantity from the right supplier. No purchase order to type.

3

See every card, pulled to restocked

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.

Built for the shop floor, not the back office

Count-everything tools fail because they add a task. Arda removes one. That is what holds compliance past week one.

No counting, ever

The card is the replenishment signal, on every item you stock. Nobody tallies stock or runs a cycle count to make the numbers real.

Adoption that holds

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.

One scan, any phone

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.

The signal lives on the floor

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.

What each role gets

Shop-floor machinist

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.

  • No hunting down whoever does the ordering. Scan the empty bin and get back to the machine.
  • No dead stop mid-setup because the insert drawer is empty and nobody caught it.
  • Nothing new to learn. If you can scan a card, you already know the whole system.

Purchasing / office manager

Orders fire at the right quantity with no stack of manual POs, and every card's status is in one place.

  • No typing purchase orders by hand or chasing the floor to find out what got used.
  • No surprise "we're out" that turns into a premium rush order.
  • Pulled, on order, restocked: every card's status in one view, so nothing inbound is a mystery.

Owner / lead

Hands off reordering for good and gets the hours back for quoting, with real consumption data across the whole shelf instead of gut feel.

  • Reordering stops eating the hours you would rather spend quoting and winning work.
  • No cheap consumable, and no missing length of bar stock, stalling an expensive machine because a reorder slipped.
  • Real consumption trends to quote materials from, instead of gut feel.

Arda vs ERP vs spreadsheets for machine-shop replenishment

Frequently asked questions

How does a two-bin kanban system work in a machine shop?
Two bins of the same item sit at the point of use, each sized to cover the supplier's lead time plus a cushion. Machinists consume from the first bin until it is empty, then pull the second forward. With Arda, the card on the empty bin gets scanned, which fires the reorder automatically. By the time the second bin runs down, the first has been refilled. No one counts stock and no one reads a number off a screen. More on the two-bin system.
What is the reorder point formula?
Reorder point equals average daily consumption multiplied by supplier lead time in days, plus safety stock. A shop that burns 40 inserts a day with a 5-day lead time and 50 units of safety stock reorders at 250. Arda encodes that number in the card quantity, so the reorder point becomes physical and no one recalculates it by hand as demand shifts. See the reorder point formula.
What is the best software for inventory management in a machine shop?
The best fit for a machine shop is software that covers every item on the shelf, not just the ones the ERP already tracks. Arda's inventory replenishment software for machine shops uses a card-and-scan kanban model that replenishes anything you stock automatically. That starts with the variable-consumption consumables the ERP never sees, cutting tools, carbide inserts, coolant, abrasives, and deburring media, and it extends to the rest of the shop as well: bar stock and raw material, fasteners and hardware, fixturing, spare parts, and packaging. It holds compliance on the floor and slots in alongside an existing ERP rather than replacing it. See how Arda works.
Does Arda work alongside my ERP?
Yes. Arda runs the replenishment loop for everything you stock and slots in where ERP and MRP fall hardest, on the variable-consumption goods that never make it onto a BOM. Your ERP keeps doing jobs, routing, and costing. It integrates with QuickBooks, NetSuite, Odoo, Xero, Shopify, Stripe, Airtable, Make, and Zapier, plus a REST API, so there is no rip and replace.
How much does Arda cost, and is there a free trial?
Arda prices by card, not by seat, so users are unlimited on every plan. The Free plan is $0 a month for up to 10 cards. Growth is $250 a month billed annually, or $291 month-to-month, and covers 250 cards at $1 a card. Pro is $500 a month billed annually for 500 cards, plus AI-tuned kanban quantities and multi-card loops. Enterprise is custom. Paid plans include a 7-day free trial, and annual plans add 2 free months and a $650 welcome kit after an onboarding call. You can start with a single part or one production line and expand across the shop when you are ready, with no months-long implementation. See full pricing.
