“The bot says incl. VAT while the displayed price is excl. VAT.” “The AI promises prices excluding tax without checking the country.” “The chatbot does not read the VAT line at checkout.” Three failures where a miscalibrated excl./incl. VAT bot hallucinates the display mode or B2B VAT routing.
An e-commerce excl./incl. VAT price AI chatbot does not replace TAXDISP agents (#805). It reads TAXDISP-MAP, quotes price_display_mode_copy ht_ttc_explain_copy by market profile, and hands off the VAT number to VATBOT without promising invented price excluding tax.
This guide #806 covers bot_taxdisp_* intents, TAXDISPbot flow, and taxdisp_bot KPIs. AI tax usecase: explaining display based on tier 1 country profile, paired with the bot of the TAXDISP playbook (#805).
Summary
Why automate the explanation of VAT-excluded and VAT-included prices using a bot?
"Price incl. VAT or excl. VAT", "VAT added at checkout", "pro account display" arrive on the PDP, cart, checkout, and widget. A calibrated bot reads market_country customer_profile, cites TAXDISP-MAP, and distinguishes display vs. calculation error without offering tax advice.
What the tier 1 bot resolves (excl. VAT / incl. VAT)
Display explain : ht_ttc_explain_copy DISPLAY-CITE-BOT map
PDP label : pdp_label_copy PDP-LABEL-CITE-BOT map
Cart tax line : cart_tax_line_copy checkout_tax_reveal_copy map
Market profile : market_country price_display_mode_copy map
Handoff escalate : #805 payload market profile cart_total
Confusion between excl. and incl. VAT generates pre-purchase abandonment if poorly explained (Shopify, taxes 2026). Without a grounded bot, the AI routes to VATBOT #465 or invents a display mode.
TAXDISPbot vs TAXDISP #805, VATBOT #465, CARTCALCbot #802 and anti-hallucination #123
