Problem statement

Portuguese law requires that customer pays a tax related with bags usage. This tax aims to reduce bags consumption to comply with environment sustainable goals. Although, this law could not be reinforced in other UE countries, it’s likely that other markets will adopt similar laws/regulations.

To comply with this law, BK PT must display of the paper bag tax value on the platform/system, which customers have to pay.

We need to show this information to the user and to the person managing delivery partners platforms (such as DMP) and Admin Tools (for support purposes).

This deliverable will be available for any other brand/market as needed.

Business requirements

This tax must be shown and applied to every service mode that requires a bag or places a takeaway order:

Delivery
Click and collect (take out/pick up)
Drive-thru
Curbside

The tax should be configured in Sanity, where we can specify which service modes will be charged and the current tax value for each service mode.

The tax value is an absolute number configured in Sanity, which will be added to the cart total. The paper bag tax will be charged once per order. The basket size doesn’t matter.

This rule will be applied to the entire market when configured (for example, BK PT). For now, this will not be a rule configured by individual or group of restaurants.

The label for the paper bag tax should be configured in the Lokalise platform, as desired.

Where does the paper bag tax need to be shown?

Sanity configuration

To configure which service mode will enable the Paper Bag Tax, the value for each one, the email receipt template, and other configurations, we have the following dedicated document: Feature - Fees and Taxes.

Delivery Partners Platforms integration

The Paper Bag Tax will be sent in the fees field of the Create Delivery Webhook using the BAG_FEE type: https://euw3-bk-partners.rbictg.com/docs/market/#tag/DeliveryWebhook/operation/deliveryCreate.

POS partners integration

POS partners should use existing API https://euw3-bk-partners.rbictg.com/docs/market/#tag/OrderAPI/operation/getOrder to read order details including bag tax (named internally as BAG_FEE) .

Feature Flags

Flags that affect all the applications where we’ll show the paper bag tax and are responsible for enabling the back-end logic:

Intl-platform

enable-bag-fee: Enable this to include the paper bag tax in the back-end logic. If disabled, the paper bag tax value will not be returned or sent to the partners' API or saved in the database
- Accepts country, region, storeId and email as filters
- If we want to condition only for a specific store we should focus on this flag because it will be the main toggle to turn the feature enable or disabled
enable-relaying-new-cart-fees-to-pos: Enable this if the cart.fees structure (which includes the paper bag tax value) should be sent to the POS partner
- Accepts only country as filter

Flags that affect only Whitelabel App:

Intl-guest-app

enable-fees-on-order-receipt: Enable if custom fees (such as the paper bag tax) should be shown on the delivery tracking modal receipt. For the “default” receipt, this flag does not need to be enabled
- Should accept any valid general filter in LD context

Flags that affect only delivery partners platform (such as DMP):
