Connecting Products preserves the base charge and discount, with formula repairs in the draft.

What changes

When connecting Products, the editor converts supported Water/Gas calculations and preserves monetary discounts. For custom formulas it explains the change and offers a proposed total in one click. The new blueprint adds the delivery charge once. Existing orders and payments keep their data.
The monetary discount applies to the full base charge + Products total, floored at zero: R$15 + R$60 − R$65 = R$10. Connecting Products also includes the base charge omitted by v6 delivery services, saving the formula and its price mode together.
The repair help explains that Deliveries v7 uses form_only with the base charge inside the formula. The formula and mode change together in the draft and should be reviewed before saving.
