E-Invoice vs. Official Receipt: What's the Difference?

If you've issued official receipts (ORs) for years, the term "e-invoice" can sound like just a digital version of the same thing. It's related, but not quite the same — and the distinction matters for compliance.

The official receipt (OR), traditionally

An official receipt is the document the BIR has long required for sales of services — proof that a customer paid for something. A sales invoice (SI), separately, has traditionally been used for sales of goods. Both are pre-printed, sequentially numbered documents issued under a BIR Authority to Print (ATP).

What an e-invoice is

An electronic invoice is a digitally generated record of a sale that is issued through a registered system (such as a Computerized Accounting System or POS) and, for covered businesses, transmitted to the BIR's Electronic Invoicing/Receipting and Sales Reporting System (EIS).

The key differences from a traditional OR/SI:

• Format — generated and stored digitally, not pre-printed in booklets
• Numbering — sequence is managed by the system, often alongside a

system-generated reference number

• Reporting — sales data is transmitted to the BIR close to the time of

the transaction, rather than only summarized later in periodic returns

• Issuance — the customer may receive a digital copy (email, QR code,

printed slip from a registered POS) rather than a manually written receipt

Is the OR/SI distinction going away?

Not immediately. The underlying distinction between invoicing for goods versus services is part of a broader, longer-running shift under the TRAIN Law toward using "invoices" as the standard term for both. For most businesses, the practical day-to-day question is less about OR vs. SI terminology and more about whether your invoicing system needs to be a registered CAS/POS that can transmit to EIS.

What stays the same

Regardless of format, an invoice/receipt still needs to show the legally required details — business name, TIN, address, date, description of the goods/services, amounts, and VAT breakdown where applicable. E-invoicing doesn't remove these requirements; it changes how the document is generated, stored, and reported.
