POS and inventory software for Dutch shops.
Peridot is a touch register and stock system for independent shops and small chains in the Netherlands. It sells, keeps stock across your stores, runs the workshop and reorders from suppliers, and every receipt follows the Dutch rules for cash registers.
A day in the shop, from the first count to the last receipt.
Peridot is POS and inventory software for Dutch shops with one to ten stores. This is a day in the demo's bike shop in Haarlem, as Peridot runs it.
Count a shelf before the doors open.
The store manager counts the helmets with a phone in hand, blind, so nobody sees what the system expects. Two come up missing, and Peridot books the difference in one go, at cost price, with a note why.
- Full or partial counts, per store
- Blind, or with the expected quantity shown
- Differences booked in one go
Stock counts are an optional module
The register opens with €150 in the drawer.
The cashier counts the float and opens Kassa 1. From then on every receipt, every cash movement and every opening of the drawer belongs to this shift, and ends up on its Z-report.
- A PIN switches cashier at a shared register
- Cash in and out with a reason
- Every drawer opening without a sale logged
A sale on the touchscreen, paid in cash.
Photo tiles and quick picks, or a scan of the barcode: a scanner types like a keyboard, so it needs no driver. Pay by card, cash, gift card or points, or split a payment, and the change is worked out for you.
- Cash rounded to 5 cents, and refused from €3,000 under the 2026 rules
- Returns against the original receipt, at the prices paid
- Park a sale and pick it up again later
A bike comes in for repair.
The repair comes in with the customer's approval limit and moves from diagnosis to waiting for approval or parts, to work in progress and ready. Parts come from stock, labour goes on the bill at 9% VAT, and the customer gets an email when the bike is ready.
- A warning when the work costs more than the customer agreed
- A work order and a pickup receipt, paid at the register
- Rush jobs and late repairs at the top of the board
The repairs module
Order before it runs out.
Peridot proposes an order per supplier: everything below its minimum, topped up to its maximum, with what sold in the last 30 days beside it and the supplier's threshold for free shipping. One click makes it a purchase order, sent by email.
- Suppliers with their lead time and minimum order
- Partial deliveries booked as they arrive
- Labels printed for whatever came in
The purchasing module
Not here? Then in another store.
Each product shows its stock in this store and in the others beside it, with its status: low, sold out, negative or on order. Stock is a ledger, so every change carries a reason and nothing is ever overwritten.
- Minimum, maximum and shelf position for every product
- Variants such as size and colour, with frame numbers for bikes
- Price labels with a barcode, on an A4 sheet or a label printer
Close the day with a blind count.
The cashier counts the drawer without seeing what Peridot expects, and only then are the two set side by side. In the demo, Kassa 1 closed after 29 receipts and €1,842.85 in revenue, with exactly the €326.60 in the drawer it should hold.
- An X-report during the day, the Z-report at closing
- A difference needs an explanation before the report is final
- Revenue, VAT per rate and payment methods per shift
Every receipt, chained to the one before.
The Dutch tax authority expects a register to keep every sale and never change one. Peridot numbers each receipt and seals it with a fingerprint that includes the receipt before it, so a change anywhere would break the chain.
Each receipt carries the fingerprint of the one before.
- CEN1-0012883FA0-6C1D-92B4
- CEN1-0012897C41-E2A8-0F5D
- CEN1-0012902BE9-1F70-A71C
Continuous numbers
Every register numbers its receipts without gaps, and a correction is a return on a new receipt.
A sealed journal
A SHA-256 fingerprint chains each receipt to the last, and Peridot checks the whole chain on request.
Every drawer opening
Opening the drawer without a sale asks for a reason and goes into the log.
X and Z reports
Close the day with a blind count, and explain any difference before the Z-report is final.
Cash by the rules
Rounded to 5 cents on the cash part only, and no cash payments of €3,000 or more.
Honest discounts
A was-price is checked against the lowest price of the 30 days before, as the ACM asks.
And how the month is going.
Revenue against the same days last month, the average receipt, the margin, and what sells and what stays on the shelf. The VAT return is split per box of the form, and every report exports to CSV for your accountant.

Works with the hardware you have.
Peridot runs in a browser on a laptop, a tablet or a counter screen. What you plug into it is ordinary shop hardware.
Barcode scanners
Any USB or Bluetooth scanner in keyboard mode. No driver, no setup.
Receipt printer
An 80 mm thermal printer, installed as a normal printer.
Labels
An A4 sheet of 3 by 8 labels, or a 57 by 32 mm label printer.
Cash drawer
Opened by the receipt printer; every opening without a sale is logged with a reason.
Card terminal
Linked through your payment provider's cloud as part of the setup. Without a link, the cashier confirms a standalone terminal's payment on screen.
Phones
Counts, stock lookups and the workshop board on any phone, without an app to install.
In the demo the card terminal is simulated: it approves after two seconds, and an amount ending in 13 cents is declined.
Pay for the modules you use.
The register and the stock are the core. Seven modules are optional, and an installation holds only the ones you take: the code for the rest is not in it at all.

Questions, answered.
Does Peridot meet the Dutch rules for cash registers?
Peridot is built on the tax authority's guidance for till systems: continuous receipt numbers per register, a journal that is never changed, every drawer opening logged, and X and Z reports. Ask your accountant to review the journal export for your business; an XAA audit file can be added if they want one.
Is Peridot only for bike shops?
No. The demo is a bike shop because it uses everything: variants, frame numbers, a workshop and reservations. Peridot suits any independent shop or small chain, and the repairs module is optional.
Which card terminals work with Peridot?
The register is ready for a terminal linked through your payment provider's cloud, such as CCV, Worldline or Adyen. Linking yours is part of the setup and is included in your quote. A standalone terminal works too: the cashier confirms the payment on screen.
Can we bring our products and customers along?
Yes. Peridot imports products and customers from a CSV file from Excel or your old system, shows what would change before anything is saved, and books the opening stock per store.
Does Peridot work in English?
The screens are in Dutch, because Peridot follows Dutch tax rules and uses their terms. This page, the setup and our support are available in English.
How does the demo work?
You pick one of four roles and get your own copy of a made-up bike shop with three stores. The PIN for the register is 2580. Only you see what you change, and the copy is deleted after 14 days.
