E-invoicing
E-invoicing from the cash register for restaurants and cafes
Issue compliant invoices right at the counter, on the same system you already use to take orders and take payment — no second application to open mid-service.
What F&B businesses need to prepare
Moving from lump-sum tax to declaring on actual revenue means the business has to capture revenue in full and issue an electronic invoice when a customer asks for one. Operationally that means the cash register becomes the point where invoices originate: every order goes through the system, with nothing written up outside it. OneXEOS issues the e-invoice straight from the payment screen, tied to the sale just closed, and keeps all revenue data on the same platform as accounting.
This describes operational requirements and is not tax advice. Regulations, revenue thresholds and effective dates are set by the tax authority and can change — confirm with your managing tax office or your accountant before acting.
Why to handle this early rather than at the deadline
Revenue has to reconcile from day one
Declaring on actual revenue requires every order to be in the system. Anything written up outside it becomes a reconciliation problem later.
Peak service has no room for extra steps
Opening a separate invoicing application and re-keying each sale will jam the lunch rush. The invoice has to be issued at the moment the bill is closed.
Know the added cost in advance
E-invoicing is usually charged per invoice issued. Knowing your monthly volume up front means buying the right bundle rather than over-buying.
The data has to be retrievable
When you need to explain a figure, you must be able to find the invoice by date, shift or customer. Data scattered across systems is a risk.
How it works on OneXEOS
E-invoicing is a step inside the existing sales flow, not a separate piece of software.
Close the bill as usual
The cashier takes payment on the same screen as always. No extra step compared with your current process.
Issue the invoice at the counter
The system creates an e-invoice tied to the sale just closed, preserving line items, discounts and payment method.
Deliver it how the customer wants
By QR code on the printed slip, by email or by phone number. If the customer declines it, the transaction is still recorded in full.
Figures flow into the books
Revenue and invoices share a platform with accounting, so at declaration time nothing is exported from one system and re-entered into another.
Pre-migration checklist
- 1Review every sales channel — counter, takeaway, delivery apps, pre-orders — and route them all into one system.
- 2Standardise the menu and prices in the system, and retire any handwritten price list.
- 3Estimate your monthly invoice volume so you buy the right bundle.
- 4Prepare the digital signature and registration details per the tax authority's guidance.
- 5Train cashiers on issuing invoices and on handling ones that need adjusting.
- 6Run a full trial shift before switching the whole shop over.
- 7Reconfirm the specific dates and obligations with your managing tax office.
Frequently asked questions
What is a register-generated e-invoice?
An electronic invoice issued at the point-of-sale device itself, tied to the transaction that just occurred, rather than raised separately in a standalone invoicing application afterwards. For restaurants and cafes — high transaction count, low value — it is the only way to issue in time without jamming the till.
My shop is small — is e-invoicing mandatory for me?
The specific obligation depends on your registration type, sector and revenue level, and is determined by the tax authority. Confirm directly with your managing tax office or accountant. On the system side, having the capability ready means you switch it on when the obligation applies rather than changing software mid-year.
If the customer does not want an invoice, do I still issue one?
Even when a customer declines, that transaction's revenue must still be recorded in full in the system. How the invoice itself is handled in that case is governed by current regulation — confirm with your accountant. On OneXEOS every transaction is recorded regardless.
How is revenue from Grab or ShopeeFood treated?
Delivery-app orders are your revenue too and need to sit in the same recording system. OneXEOS syncs orders from the delivery platforms into one feed, so revenue reporting already includes them instead of being added up by hand from each app.
How is e-invoicing priced?
Typically per invoice issued, bought in bundles. Estimate monthly volume from your actual bill count before choosing one. Ask for the unit price, the minimum bundle size and what happens if you exhaust a bundle mid-period.
Will switching from another system cause disruption?
Not with preparation. The usual approach is to migrate after closing, run both systems in parallel for a few days to reconcile shift-close revenue, and only then retire the old one. Avoid switching immediately before a declaration deadline.
