If you are a **wholesaler** selling to VAT-registered businesses, the 2029 mandate applies to you squarely. From **April 2029**, your VAT invoices to business customers and public bodies must be structured e-invoices, and the government has confirmed Peppol as the network. If you are a **retailer** selling to consumers, most of your sales produce receipts, not VAT invoices, so the core obligation hits your B2B sales and your purchase ledger rather than the till.

## The line that matters: VAT invoice or not?

The mandate is about **VAT invoices**. HMRC's [consultation response](https://www.gov.uk/government/consultations/promoting-electronic-invoicing-across-uk-businesses-and-the-public-sector/outcome/promoting-electronic-invoicing-across-uk-businesses-and-the-public-sector-consultation-response) puts it plainly: VAT invoices "are typically issued for business to business (B2B) and business to government (B2G) transactions where VAT is due (though not for business to customer transactions)".

[VAT Notice 700](https://www.gov.uk/guidance/vat-guide-notice-700) sets the current rules:

- You must give a VAT invoice when you make a **standard- or reduced-rated** supply to a **VAT-registered** customer (paragraph 16.2.1).
- You don't need to issue VAT invoices for **zero-rated** supplies, or to customers who are **not VAT-registered**.
- Retailers must issue a VAT invoice when a customer asks for one, and may face a penalty for refusing a taxable person (16.6.2).

That gives a rough map of where the mandate lands:

| Transaction | Document today | Mandate position |
|---|---|---|
| Wholesale sale to a VAT-registered trade customer | Full VAT invoice | **In scope** from April 2029 |
| Sale to a council, NHS body or department | Full VAT invoice | **In scope** (B2G) |
| Retail sale to a consumer | Till receipt | Outside VAT invoicing; B2C not covered |
| Retail sale of £250 or less to a business customer | Simplified or retailer's VAT invoice | **Not yet confirmed** |
| Retail sale over £250 to a business that asks | Full VAT invoice | Likely in scope; detail not confirmed |
| Zero-rated wholesale sale (for example most food) | VAT invoice optional | **Not yet confirmed** |
| Cash and carry till roll used as VAT invoice | Adapted till roll | **Not yet confirmed** |

## Simplified and retailers' invoices

For supplies of **£250 or less**, VAT Notice 700 (16.6) allows a **simplified invoice** if the customer agrees. A retailer may also issue a **retailer's VAT invoice**. Both show only your name, address and VAT number, the tax point, a description, and the VAT-inclusive total and rate for each VAT rate. A card voucher can be adapted to serve as one.

These documents need no invoice number and no buyer details, and they show VAT-inclusive totals. That makes them a poor fit for a Peppol invoice, which needs buyer identification and a separate VAT breakdown. The government has not yet said how **simplified invoices and receipts** will be treated. It is one of the questions we expect the roadmap to address. See [do retail receipts need to be e-invoices?](https://einvoices.uk/news/b2c-receipts-simplified-invoices-e-invoicing)

## Cash and carry wholesalers

Paragraph 17.2 of Notice 700 lets a cash and carry adapt **till rolls** to serve as VAT invoices. The conditions are:

- a product coding system of at least two digits that identifies classes of goods
- up-to-date code lists given to VAT-registered customers
- all full VAT invoice details on the till roll
- copies kept for six years

Trade customers of a cash and carry are VAT-registered businesses, so these are B2B VAT invoices in principle. **Whether the till-roll method survives the mandate, or whether cash and carries will need to issue a Peppol invoice for each trade sale, is not yet confirmed.** It is one of the clearest sector questions for the roadmap.

## EDI in retail supply chains

Large grocery and retail supply chains have used **EDI** for years, with formats agreed between trading partners. That is real e-invoicing, but not necessarily the kind the mandate will require:

- **Network.** The government has [announced](https://www.gov.uk/government/publications/summary-of-tax-update-2026-simplification-modernisation-and-fairness/tax-update-2026-simplification-modernisation-and-fairness-summary) that Peppol will be "the core interoperability network for e-invoicing in the UK". It has also said it will keep engaging on the role of **legacy systems** that cannot interoperate.
- **Standard.** The UK data standard is still to be published. Peppol BIS Billing 3.0, based on EN 16931, is the obvious candidate, but it is not confirmed.
- **Duplicates.** HMRC's [Electronic invoicing notice](https://www.gov.uk/guidance/electronic-invoicing-notice-70063) warns against "dual systems" that send electronic and paper invoices for the same supplies, outside a controlled trial. Moving channels needs a clean cut-over.

See [e-invoicing vs EDI](https://einvoices.uk/news/e-invoicing-vs-edi) for a fuller comparison.

## Wholesale invoicing pain points to fix now

Structured invoices are validated line by line. These wholesale habits cause the most trouble:

- **Mixed VAT rates on one invoice.** Food (often zero-rated) and non-food (standard-rated) lines need correct VAT category codes and a breakdown per rate. Zero-rated lines must not carry an exemption reason. See [VAT category codes](https://einvoices.uk/news/uk-vat-category-codes-peppol).
- **Promotional and retrospective discounts.** Notice 700 (18.2) lets you leave the original VAT unadjusted for a contingent discount, if both sides agree and the customer can recover all the VAT. Otherwise you issue a credit note. Decide which you do and make your credit notes structured too. See [credit notes in Peppol](https://einvoices.uk/news/credit-notes-peppol-uk).
- **Rounding.** Notice 700 allows rounding at line or invoice level, consistently, but retailers calculating VAT at line level must not round down (17.6). Peppol validation checks the arithmetic. See [BR-CO-15](https://einvoices.uk/news/peppol-validation-error-br-co-15).
- **Customer master data.** Trade customers' VAT numbers and legal names need to be right for Peppol addressing. See [master data cleanup](https://einvoices.uk/news/master-data-cleanup-e-invoicing).
- **Northern Ireland.** Goods sold from or to Northern Ireland may involve XI VAT numbers and EU rules. See [Northern Ireland and XI VAT](https://einvoices.uk/news/e-invoicing-northern-ireland-xi-vat).

## On the buying side

Retailers and wholesalers usually *receive* many more invoices than they send. From 2029, VAT-registered suppliers will send you e-invoices, so your accounts payable system must be able to receive and process them through an Access Point. That is where the efficiency gains usually show up first. See [accounts payable and e-invoicing](https://einvoices.uk/news/accounts-payable-e-invoicing-uk).

## What to do now

1. **Split your sales** into B2C, B2B under £250, B2B over £250 and public sector. Count invoices in each group.
2. **List your EDI partners**, and ask your EDI provider about its Peppol plans.
3. **Test your VAT coding** for mixed-rate baskets.
4. **Wait for the roadmap** (Budget, 28 October 2026) before rebuilding till or receipt processes. That part is genuinely unknown.

## Frequently asked questions

### Do wholesalers need e-invoicing from 2029?

Yes, for VAT invoices to VAT-registered business customers and public bodies. From April 2029 those must be issued as e-invoices. Peppol is the confirmed network.

### Do shop receipts have to be e-invoices?

The mandate covers VAT invoices, and VAT invoices are not normally needed for sales to consumers. How simplified invoices and receipts given to business customers will be treated has not been confirmed.

### Can a cash and carry till receipt count as a VAT invoice?

Today, yes, if the cash and carry meets HMRC's conditions in VAT Notice 700 paragraph 17.2, including product codes and full VAT invoice details. Whether that will still be allowed after April 2029 is not yet known.

### We already use EDI with our retail customers. Is that enough?

Not necessarily. Peppol is the confirmed national network, and the UK data standard has not yet been published. Many EDI providers may connect to Peppol, but check with yours.
