Sales Invoice vs Official Receipt: What the BIR Requires

Since April 2024, the Official Receipt is no longer the BIR’s primary proof of sale. The Sales Invoice is, both for goods and for services. Most Philippine businesses have made the switch on paper. Far fewer have caught the part that actually costs money: the invoice you issue is now the document that starts your tax clock, whether or not your customer has paid you.

This guide covers what to issue, when to issue it, and the two documents most SMEs still get wrong.

The short answer

The Invoice is now the principal document for sales of both goods and services. Depending on the transaction, it may be called a Sales Invoice, Service Invoice, Billing Invoice, or another permitted invoice designation.

An Official Receipt is now a supplementary document. It proves money changed hands. It is no longer valid on its own as proof of the sale, and it cannot be used by your buyer to claim input VAT.

What changed, and why

The Ease of Paying Taxes Act (Republic Act No. 11976) was signed in January 2024. The BIR implemented its invoicing provisions through Revenue Regulations No. 7-2024, effective 27 April 2024, later amended by RR No. 11-2024.

Before this, the rule was split by transaction type. Sell goods, issue a Sales Invoice. Sell services, issue an Official Receipt. It was a distinction that existed nowhere else in the region and confused everyone, including the people enforcing it.

RR 7-2024 collapsed the two. Now:

• Sales Invoice (or Service Invoice) is the principal document for all sales – goods, services, or both.
• Official Receipts, Collection Receipts, Billing Statements, order slips, and delivery receipts are supplementary. They support your books. They do not stand in for the invoice.
• Supplementary documents are not valid for claiming input VAT. If your supplier hands you an OR and nothing else, you cannot claim the VAT on it.

Businesses can still use properly converted unused manual or loose-leaf ORs as Invoices until they are fully consumed. The separate transition period for ORs generated by POS, CAS, and electronic invoicing systems ended on 31 December 2024.

Which document do I issue? A lookup by transaction

Here is the part you actually need: what to issue in the situations Philippine SMEs run into every week.

The supporting documents that trip people up

Three documents sit around the invoice, and mixing them up is one of the most common findings in a BIR audit.

1. Billing Invoice — a demand for payment. Under RR 11-2024, existing Billing Statements and Statements of Account can be converted into Billing Invoices. Common in construction, agencies, and long-term service contracts.
2. Collection Receipt — proof that you received payment against an invoice already issued. Supplementary. Optional unless your customer asks for one.
3. Acknowledgement Receipt — not a BIR principal document. It has no standing as proof of a sale and cannot support input tax.

The pattern: one principal document per sale, plus whatever supplementary documents your business process needs. If you find yourself issuing two principal documents for one transaction, something is wrong.

What a compliant invoice must contain

Per Section 6(B) of RR 7-2024, a VAT invoice must show:

• A statement that the seller is VAT-registered
• Seller's registered name, business address, and TIN with branch code
• Date of transaction
• Invoice number
• Quantity, unit cost, and description or nature of the goods or service
• Total amount, with VAT shown as a separate line
• For a sale of PHP 1,000 or more to a VAT-registered buyer, include the buyer's registered name, address, and TIN.
• The words “VAT-exempt sale” or “zero-rated sale” where they apply
• For mixed sales: a clear breakdown of VATable, VAT-exempt, and zero-rated amounts

Non-VAT businesses issue a Non-VAT Invoice with the equivalent details, minus the VAT lines. Failure to issue a compliant invoice can expose the taxpayer to penalties under Section 264 of the Tax Code, including a fine of PHP 1,000 to PHP 50,000 and imprisonment of two to four years upon conviction.

A non-VAT business that issues a VAT invoice gets hit hardest: it becomes liable for the VAT shown, without input tax credit; surcharges (25% or up to 50% in fraud cases) and interest may apply, plus percentage tax where applicable. If you are not VAT-registered, make sure your printer did not hand you VAT-labelled forms.

VAT can be due before you get paid

The Ease of Paying Taxes Act moved VAT on services from a cash basis to an accrual basis. For VAT purposes, sales are now generally recognized when the sale occurs rather than when payment is collected. For services, that means output VAT can become due before your customer pays.

So an unpaid invoice can create an output VAT liability before the cash reaches your account. You may have to fund that VAT from your own working capital and settle it in the quarter when the sale is recognized, not when your customer eventually pays.

Illustrative. Actual exposure depends on where your invoice dates fall in the VAT quarter and how quickly your customers pay.

For a services business billing PHP 1M a month on 45-day terms, that is real working capital going out the door ahead of the cash coming in. Slow collections used to be an annoyance. Now they are a financing cost.

The clause on your invoice that lets you claw it back

There is relief for genuinely uncollected receivables – an output VAT credit – but it comes with conditions most SMEs fail without realising it. Under RR No. 3-2024, to claim it:

1. The sale must have been on credit or on account, made after 27 April 2024
2. There must be a written agreement specifying the credit term
3. The credit term must be stated on the invoice, with VAT shown separately
4. You must have already declared and paid the output VAT on that sale
5. The sale must be listed specifically in your Summary List of Sales — not lumped under “various”
6. The credit term must have lapsed, and you claim in the following quarter
7. You stamp “Claimed Output VAT Credit” on the invoice
8. You have not claimed the same VAT as a bad debt deduction

Two things to plan for: your buyer is required to reverse the corresponding input tax, and if the customer eventually pays, you add the output VAT back in the quarter you recover it.

Two 2026 deadlines already on the calendar

The invoice-versus-receipt rules are settled. What is still moving is the format your invoice has to take.

1. Electronic invoicing — 31 December 2026. Under RR No. 11-2025, as amended by RR No. 26-2025, mandatory e-invoicing and electronic sales reporting to the BIR's EIS applies to Large Taxpayers Service registrants, large taxpayers under the EOPT classification, e-commerce sellers (micro businesses excluded), and users of Computerised Accounting Systems or invoicing software. The deadline moved from 14 March 2026 to 31 December 2026. Exporters, POS users, and registered business enterprises with incentives follow once the BIR's systems are ready.
2. “VAT on Local Sales” labelling — 31 December 2026. RR No. 1-2026 requires registered business enterprises to update their invoicing systems to show “VAT on Local Sales” by the end of the year.

If you sell online, treat the first one as a live deadline, not a someday problem. Systems work of this kind takes longer than anyone plans for.

Get paid closer to the date you invoice

The compliance fix is a template change. The expensive problem is the gap between the day you issue an invoice and the day the money arrives because the BIR now starts counting from the first date, not the second.

PayMongo Invoices shortens that gap. You build the invoice in your dashboard, send it as a hosted link, and your customer pays it on the spot with GCash, Maya, credit or debit card, QR Ph, or online banking – no bank transfer screenshots, no chasing. 

You see status at a glance: draft, awaiting payment, paid, overdue. And when payment lands, you have a timestamped record of the exact amount and date, which is precisely what you need to support the document you issue.

PayMongo Invoices is your billing and collection layer, not your BIR document. Your registered Sales Invoice or Service Invoice is still the principal document you issue to your customer. What PayMongo removes is the waiting.

What to do this week

1. Stop printing ORs as your primary document. Order Invoices with your next ATP.
2. Audit your invoice template against the required-fields list above. The buyer TIN field and the separate VAT line are the usual gaps.
3. Add a payment terms line to every invoice. It is the price of admission for the output VAT credit.
4. Look at your average days-to-collect. Multiply your monthly billings by 12%. That is roughly what your collection cycle is costing you in fronted VAT.
5. Make your invoices payable in one click. The shorter the gap between invoice date and payment date, the less of your own cash you are lending the BIR.
