Restaurant E-Invoice System: Issued Right at POS Checkout, Built In — Not an Add-On
Issuing, carriers, voids, and allowances — all on the same POS
OrderEase e-invoicing is built into the PRO plan: invoices are issued at POS checkout and uploaded to the Ministry of Finance, with mobile barcode carriers and donation supported, and refunds automatically linked to voids and allowances — no extra module fee.
Issuing at Checkout: Payment Done, Invoice Out
From checkout to Ministry of Finance upload, the only extra step is asking about the carrier
The old way: finish checkout on the POS, then walk to a separate invoice machine and re-key the amount — one more device, one more entry, one more chance to make a mistake. OrderEase builds e-invoicing directly into the checkout flow: once payment completes, the invoice amount, items, and tax are filled in automatically, the carrier is captured with one scan of a barcode scanner, and the whole process never leaves the POS screen or needs a second machine.
Check Out on the POS
Staff ring up the items and take payment, and the system immediately starts the invoice flow. Cash, credit card, LINE Pay, and other payment methods all work; the amount and items carry over from the order, so nothing is re-keyed and nothing gets mistyped.
Ask About Carrier or Donation
Customer wants the invoice stored on their mobile barcode carrier? One scan with the barcode scanner and it is done. Citizen Digital Certificate and membership carriers are supported too, and customers can also donate the invoice to a charity. If the customer has nothing on hand, a paper certificate copy prints straight from the receipt printer.
Automatic Upload to the Ministry of Finance
After the invoice is issued, the system uploads the invoice data to the Ministry of Finance E-Invoice Platform through your value-added center automatically. Staff never file anything manually or export files, and the issuing history is always visible in the back office.
Customer Receives the Invoice
Invoices stored on a carrier go straight into the customer's carrier account and join the lottery draw automatically; customers who want paper get the certificate copy on the spot. Every invoice maps to one order, so reconciliation in the back office is straightforward.
Voids and Allowances: Linked to Refunds, No Separate System to Log Into
When an issued invoice needs a refund or a correction, the system walks the correct procedure for you
Full Refund, Automatic Void
When an order is refunded in full, the system automatically voids the corresponding invoice. Invoice status stays in sync with order status — no gap where the money is refunded but the invoice is still standing, and no separate value-added center back office to log into.
Partial Refund, Allowance Issued
When only some items or part of the amount is refunded, the correct procedure is not to void and re-issue but to issue an allowance. OrderEase links partial refunds to the allowance flow automatically, with the allowance amount matching the actual refund so the books balance.
Found a Mistake After Issuing
If you discover a wrong item or amount after the invoice is issued, the correct procedure is to void the original invoice (or issue an allowance) first, then re-issue with the correct details. For deadlines and rules on voids and allowances, always follow the announcements of the Ministry of Finance and the National Taxation Bureau.
How Much Extra Does E-Invoicing Cost?
With OrderEase: module fee NT$0 — the only extra cost is the value-added center's transmission fee
The OrderEase e-invoice module is built into the PRO plan (NT$2,450/month). Issuing, carriers, donation, voids, and allowances are all included, with no extra module fee, setup fee, or activation fee. Only two costs sit outside the plan: the invoice track number, which your business applies for from the National Taxation Bureau free of charge; and invoice data transmission, which requires a contract with a value-added center (such as ECPay). That transmission fee is a contract between your business and the value-added center — OrderEase does not handle it or mark it up, so ask the value-added center directly for actual rates.
| Cost Item | Who Pays, Paid to Whom | Cost with OrderEase |
|---|---|---|
| E-invoice module fee | Paid to the POS vendor | NT$0, built into the PRO plan (NT$2,450/month) |
| Module setup / activation fee | Paid to the POS vendor | NT$0, self-service setup in the back office, with setup assistance provided |
| Invoice track number application | Your business applies to the National Taxation Bureau | Free (the National Taxation Bureau charges no application fee) |
| Value-added center transmission fee | Your business pays the value-added center (e.g. ECPay) | Agreed in your contract with the value-added center; OrderEase does not handle or mark it up — ask the value-added center for rates |
Restaurant POS vendors price e-invoicing in very different ways: some sell it as a separately purchased module with a monthly surcharge, some only include it in their top-tier plan so issuing invoices forces a full upgrade, and some bundle invoice hardware with the system. None of this is necessarily unreasonable — but it often only becomes clear right before you sign. Before buying any POS, get this in writing: is e-invoicing built in or an add-on? How much per month if it is an add-on? Is it locked to a specific plan?
The E-Invoice Application Process: Four Steps from Zero to Your First Invoice
The applicant is your business — OrderEase helps with the back-office setup
To be clear up front: the applicant for e-invoicing is your business itself. The track number assignment and tax registration are tied to your unified business number, and no system vendor can complete that part for you. What OrderEase does is make the setup and testing after approval simple. The steps below are for reference; for actual application requirements, documents, and procedures, follow the announcements of the Ministry of Finance and the National Taxation Bureau.
Apply to the National Taxation Bureau for a Track Number
Your business (the business entity) applies to its National Taxation Bureau office to use e-invoicing and receives its track number assignment. The application itself is free of charge; confirm required documents and eligibility directly with your taxation bureau office.
Sign with a Value-Added Center
Choose a value-added center (such as ECPay) and sign a contract to obtain the transmission service and integration credentials. The transmission fee is agreed between your business and the value-added center — OrderEase takes no part and no cut.
Complete the Setup in the OrderEase Back Office
Enter the integration credentials from your value-added center into the e-invoice settings in the OrderEase back office, binding your unified business number and track number. In multi-store mode, each branch can bind its own business number and report invoices independently. If you get stuck, support will walk you through it.
Issue a Test Invoice, Then Go Live
Before going live, issue a test invoice to confirm that issuing, uploading, and voiding all work, then start issuing to customers. From then on, every checkout carries its invoice automatically.

Does my restaurant have to issue e-invoices?
Under current regulations, businesses that reach the threshold for using uniform invoices must issue them; the e-invoice is the electronic form of the uniform invoice and the direction the Ministry of Finance has been promoting in recent years. Whether your restaurant reaches the threshold and which tax registration applies depends on your individual situation — the determination rests with your National Taxation Bureau office, so confirm with them directly.
I currently handwrite invoices. Can I keep doing that?
Paper uniform invoices can still be used at present; whether and when to switch to e-invoicing should follow the announcements and regulations of the Ministry of Finance and the National Taxation Bureau. In practice, e-invoicing removes the work of handwriting invoices, checking each one against the lottery, and storing stubs, and checkout is faster during peak hours — which is why most restaurants switch voluntarily.
How do I scan a customer's mobile barcode carrier?
With a barcode scanner. The customer shows their mobile barcode carrier, staff scan it once, and the carrier number is filled into the invoice — no manual typing. Citizen Digital Certificate barcodes scan the same way. Without a scanner, the carrier number can also be entered manually on the POS.
An invoice was issued wrong — do I have to visit the taxation bureau to void it?
No counter visit is needed. Run the void or allowance in the OrderEase back office and the system uploads the information to the Ministry of Finance through your value-added center. Note that voids and allowances are subject to processing deadlines and related rules — follow the National Taxation Bureau's announcements.
What happens when a customer's invoice wins the lottery?
Invoices stored on carriers such as the mobile barcode join the draw automatically, and winners claim prizes in the manner prescribed by the Ministry of Finance; for donated invoices, winnings go to the recipient charity. The restaurant does not need to do anything extra for the draw. For claiming details, follow the Ministry of Finance's announcements.
