"The bot says pack of 4 while the spec sheet indicates 6." "The AI doesn't understand why I can't add 3 to the cart." "Transferred without explaining that 1 qty = 12 pieces." Three bot failures where the AI invents a pack rule, confuses wholesale MOQ and SKU qty, or routes an order edit without an order status.
An e-commerce cart quantity AI chatbot does not replace CARTQTY-FLOW agents (#474). It classifies bot_cartqty_* intents, lookups grounded CARTQTY-MAP SKU, explains lot increment unit pack max, guides PDP cart self-service, and hands off post-purchase order edits.
This guide #475 covers intents bot_cartqty_*, flow CARTQTYBOT, and KPI cartqty_bot. Distinct from the qty playbook (#474) and the future MOQ (#476): here, AI use case to explain cart minimum unit lots.
Summary
Why automate cart quantity support with a bot?
Qty questions arise on PDP, cart, and checkout when the customer hesitates before purchasing and a generic bot does not read CARTQTY-MAP.
Bot cartqty volume and opportunity
70 to 82% of cartqty_pre_purchase tickets are botifiable as tier 1 if CARTQTY-MAP is grounded and NO-INVENT-LOT guardrails are active.
Three risks of an uncalibrated qty bot
Invent lot size: LLM quotes pack of 4 without SKU API
MOQ confusion: € threshold confused with SKU pack
Wrong route dup: two orders processed for cart qty
Baymard notes that clear quantity feedback reduces mobile abandonment by 8 to 15% (Baymard, mobile 2025). Fin reminds to look up product before AI agent response (Fin, AI agents 2026).
Angle #475 vs neighboring content
CS qty #474: CARTQTY-FLOW agents. #475 = tier 1 explain bot.
MOQ #476: future wholesale order threshold. #475 = qty SKU pack reroute MOQ.
Duplicate #473: bot dup. #475 = qty one order.
Saved cart #438: restore cart bot. #475 = qty rules explain.
Fresh fees bot #411: checkout fees. #475 = qty not fees.
DTC Food & Beverage Example
38 cartqty tickets/month baseline #474. After CARTQTYBOT: cartqty_bot_auto_resolve 79%, cartqty_bot_invent_lot 0, cartqty_bot_csat 4.5/5.
Bot explains, does not execute edit
CARTQTYBOT-SUP: bot guides qty on PDP, hands off for order edit, #474 CQ-7 agents execute.
PDP pre-add cart peak
58% of cartqty bot sessions occur before add-to-cart: CARTQTYBOT T1 chip is critical at the conversion moment.
Cart drawer error hook
Cart validation error for lot multiple: trigger proactive T2 bot_cartqty_cannot_add_qty to reduce ticket lag.
Grocery category bot corpus
Preload drinks, diapers, canned foods in CARTQTY-MAP rows for highest cartqty_bot_session_rate categories.
How does CARTQTYBOT differ from CARTQTY #474 and MOQ #476?
Playbook human qty, bot MOQ wholesale future, and bot qty cart: three layers of bot conversion.
Bot → qty role matrix
#475 CARTQTYBOT: SKU lot increment explain guide
#474 CARTQTY-FLOW: agents post-order edit execute
#476 MOQ future: cart subtotal threshold wholesale
#438 SCART-BOT: saved cart restore
#473 DUPBOT: duplicate orders pair
Shared CARTQTY-MAP corpus
#474 defines CARTQTY-MAP JSON. #475 bot consumes: lot_size increment_step units_per_unit max_qty pdp_disclosure.
Four BOT-CARTQTY-TYPE flows
bot_cartqty_pdp_guide: how adjust qty lot explain
bot_cartqty_lot_block: cannot add 3 lot 6 explain
bot_cartqty_pack_units: 1 qty = N pieces clarify
bot_cartqty_post_order: ordered too much handoff edit
Promise #475
Policy CARTQTYBOT-SUP, 12 intents bot_cartqty_*, flow CARTQTYBOT CBQ-1 to CBQ-8, guardrails, handoff payload, KPI cartqty_bot_*.
Bot ops 30 minutes training
Module 1: lot vs MOQ vs dup. Module 2: guardrail red team check fake lot. Module 3: valid qty calculator demo. Quiz 90 % before prod.
Conversion widget placement A/B
PDP chip above vs below add-to-cart test cartqty_bot_pre_purchase_save 4 weeks.
Which bot_cartqty_* intents should be classified?
Twelve cart quantity bot intents before the CARTQTYBOT flow.
Twelve bot_cartqty intents
bot_cartqty_how_adjust: how to change cart quantity
bot_cartqty_lot_explain: why in slots of 6
bot_cartqty_cannot_add_qty: unable to add 3 blocked
bot_cartqty_pack_units: 1 = how many pieces
bot_cartqty_increment_step: steps of 5 10 only
bot_cartqty_max_limit: ceiling of 10 why
bot_cartqty_min_required: minimum 2 to add to cart
bot_cartqty_mobile_plusminus: +/- adds too much on mobile
bot_cartqty_moq_reroute: order threshold € blocked
bot_cartqty_post_order_wrong: ordered too many handoff
bot_cartqty_dup_reroute: two orders not qty
bot_cartqty_oos_at_qty: stock max available
Bot execution tier
Tier 1 auto: lot_explain, pack_units, increment_step, max_limit, min_required, mobile_plusminus, how_adjust.
Tier 2 handoff: post_order_wrong, moq_reroute explain + agent if needed.
Bot session fields
cartqty_intent, sku, qty_requested, lot_size, increment_step, units_per_unit, max_qty, order_id optional, pre_post_purchase flag.
Intent router qty keywords
"pack of", "by 6", "cart quantity", "impossible 3", "how many pieces" route CARTQTYBOT before generic cart macros.
Post-handoff bot silence
After order edit handoff CBQ-7: bot stops qty guidance during the same session to prevent contradictory steps.
How does the bot consume CARTQTY-MAP #474?
The bot reads CARTQTY-MAP #474 for grounded qty rules without inventing lot size.
Lookup CBQ-4 bot
sku → lot_size_min: mandatory multiple
increment_step: +/- step quoted
units_per_unit: pieces per qty
unit_label_fr: box carton pack lot
max_qty_cart: limit reason
pdp_disclosure: exact customer text
Product API CBQ-3
Shopify product variant metafields custom.lot_size sync CARTQTY-MAP verify before respond.
Collection fallback
SKU no row: collection inherit rules CBQ-4 collection CARTQTY-MAP not LLM default.
Valid qty calculator
bot_cartqty_cannot_add_qty: bot computes next valid qty 6 12 18 from grounded lot_size.
RAG /pages/cart-quantity
Corpus CARTQTY-* macros #474 + FAQ link every cartqty thread.
Stale CARTQTY-MAP alert
Bot RAG hash mismatch #474: block lot answers handoff until sync.
Multi-SKU cart session
Client asks qty rules product A in cart with B: CBQ-3 lookup SKU mentioned message context.
Market localized unit labels
CARTQTY-MAP market FR UK: bot responds unit_label_fr or EN per session locale same lot_size numbers.
How to write the CARTQTYBOT-SUP policy in eight rules?
The CARTQTYBOT-SUP bot qty policy structures explain grounded without invent lot or execute edit.
Eight CARTQTYBOT-SUP rules
CARTQTY-MAP grounded only: lot step units from map API
NO-INVENT-LOT: block lot size not in map
MOQ-REROUTE: cart subtotal threshold → #476 not lot macro
DUP-REROUTE: two orders keywords → #473 DUPBOT
NO-EXECUTE-EDIT: post-order handoff agents CQ-7
Compute valid qty: suggest next lot multiple not guess
Handoff payload SKU rules: lot_size qty_requested order fulfillment
/pages/cart-quantity link: once per cartqty thread
Bot prohibited actions
Waive lot policy bot. Promise order edit shipped. Invent units_per_unit. Confuse saved cart #438 qty stale as lot bug.
Pre vs post purchase gate
CBQ-2: no order_id pre-purchase guide only. order_id post → fulfillment check before edit promise.
Fulfillment gate post-order
CBQ-2 order API fulfillment_status null before edit handoff promise not TPL edit if shipped.
Collection inherit explain
CBQ-4 cite collection rule source when SKU inherits: transparency reduce invent_lot disputes.
How do I apply the CARTQTYBOT CBQ-1 to CBQ-8 flow?
The CARTQTYBOT CBQ-1 to CBQ-8 flow structures triage qty bot grounded maps.
Eight steps CBQ-1 to CBQ-8
CBQ-1 Intent classify: bot_cartqty_* from message
CBQ-2 Context gate: pre-purchase sku | post order_id email
CBQ-3 SKU product lookup: variant metafields CARTQTY-MAP
CBQ-4 Rules match: lot increment max units disclose
CBQ-5 Reroute check: MOQ dup saved_cart branches
CBQ-6 Respond tier 1: TPL-CARTQTYBOT-* grounded CBQ-4
CBQ-7 Branch: close guide | handoff order edit | moq explain | product bug
CBQ-8 Log: intent sku valid_qty_suggested handoff csat
CBQ-6 bot_cartqty_lot_explain
TPL-CARTQTYBOT-LOT: sold by [N], valid qty [N] [2N] [3N], 1 = [units_per_unit] [unit_label].
CBQ-6 bot_cartqty_pack_units
TPL-CARTQTYBOT-PACK: 1 quantity = 1 [box] of [12] pieces. For [24] pieces qty 2.
CBQ-7 bot_cartqty_post_order_wrong
Unfulfilled handoff order edit payload. Fulfilled return policy link #474 CARTQTY-POST-ORDER-01.
CBQ-6 bot_cartqty_mobile_plusminus
TPL-CARTQTYBOT-MOBILE: type qty manual, wait 1 s between +, debounce tip.
CBQ-2 SKU from URL context
PDP page context prefill sku reduce client re-type product name errors.
SLA bot tier 1 cartqty
CBQ-6 TPL response under 5 s. Post-order handoff ack under 10 s with ticket ref.
CBQ-5 saved cart branch
"Cart recovered qty locked": verify #438 restore then CARTQTY-MAP current rules not stale assume bug.
Which TPL-CARTQTYBOT-* templates and guardrails?
Eight cart quantity bot templates and NO-INVENT-LOT guardrails.
TPL-CARTQTYBOT-LOT
" [Product] sold in packs of [N]. Add [N], [2N] or [3N] to the cart. 1 pack = [units_per_unit] [units]. /pages/cart-quantity "
TPL-CARTQTYBOT-PACK
" 1 in cart = 1 [box] of [12] pieces. Total pieces = quantity × [12]. "
TPL-CARTQTYBOT-STEP
" Quantities by [5]: try [5], [10], [15]. + Button advances by [5]. "
TPL-CARTQTYBOT-MAX
" Maximum [10] per order ([stock/promo]). Reduce qty or contact pro order support. "
TPL-CARTQTYBOT-VALID-NEXT
" [3] impossible. Next valid qty: [6] (= [1] pack). "
TPL-CARTQTYBOT-MOBILE
" Mobile: enter the number directly. Wait 1 second between each +. "
Guardrail NO-INVENT-LOT-01
Block lot_size units_per_unit not matching CARTQTY-MAP API within session.
Guardrail MOQ-REROUTE-01
Checkout blocked subtotal MOQ keywords route moq explain not lot macro.
Touchpoints
PDP chat chip "Quantity and packs?" T1
Cart drawer qty error T2 proactive
/pages/cart-quantity T3 bot embed
Checkout block message T4 bot_cartqty_moq_reroute
TPL-CARTQTYBOT-HANDOFF
" Agent transfer for order modification #[X] qty [requested]. Not shipped: modification possible within [SLA]. "
Checkout summary qty bot
T4 checkout "2 packs = 12 units" confirm chip opens bot_cartqty_pack_units clarify last mile.
Which MOQ, dup, and subscription cases should be processed?
Special bot cartqty cases require immediate reroute or handoff.
MOQ checkout block
bot_cartqty_moq_reroute: "Order threshold [€500] not product qty. Add items or see #476 MOQ." Not TPL-CARTQTYBOT-LOT.
Dup two orders reroute
"Two identical orders": #473 DUPBOT not cartqty qty selector.
Subscription qty
Recurring portal edit distinct cart one-time bot_cartqty_how_adjust reroute.
Saved cart stale qty
#438 restore: re-verify CARTQTY-MAP rules may have changed.
Bundle SKU qty 1
Bundle flag CARTQTY-MAP: 1 qty = complete kit not single unit lot.
OOS partial stock
bot_cartqty_oos_at_qty: max [12] available not lot bug TPL-CARTQTYBOT-MAX stock reason.
Shared cart #444
Co-purchase qty conflict: route shared cart bot not CARTQTYBOT single buyer.
B2B case pack light
Case 24 explain lot. Full wholesale MOQ → #476 when live.
Promo max qty dynamic
CARTQTY-MAP promo_end_date: bot cites active flash limit not permanent max.
Mixed subscription cart future
#504 mixed cart: qty rules differ by line type, bot classifies subscription vs one-time separate.
Gift qty same rules
#205 gift buyer qty 2: same CARTQTY-MAP lot rules, no gift exception bot.
Which cartqty_bot KPIs should be measured?
The cart quantity bot KPIs link auto-resolve, zero inventory lot, and conversion save.
Eight key metrics
cartqty_bot_session_rate : bot_cartqty sessions / qty chats
cartqty_bot_auto_resolve : tier 1 closed / sessions
cartqty_bot_pre_purchase_save : checkout completed post bot guide / eligible
cartqty_bot_invent_lot : guardrail violations (target 0)
cartqty_bot_moq_reroute_accuracy : correct MOQ vs lot / moq intents
cartqty_bot_handoff_quality : payload complete / handoffs
cartqty_bot_valid_qty_accept : client adds suggested qty / sessions
cartqty_bot_csat : satisfaction post cartqty bot
DTC lots Benchmark
cartqty_bot_auto_resolve 75-85 %, invent_lot 0, pre_purchase_save uplift 8-15 %, cartqty_bot_csat > 4.3/5.
Conversion bot dashboard
Intent breakdown, PDP vs cart touchpoint, moq reroute rate, post_order handoff funnel.
cartqty_bot_abandon_delta
Measure checkout abandon rate sessions with bot_cartqty_lot_explain vs control SKU subset.
cartqty_bot_ticket_delta agents
Target 60-75 % cartqty tier 1 deflection post-CARTQTYBOT maintain handoff quality.
valid_qty_accept tracking
Pixel or cart API event client sets suggested qty within 5 min bot session measure calculator effectiveness.
Which cartqty bot anti-patterns should be avoided?
Twelve cart quantity bot anti-patterns to ban from production.
1. Invent lot size
NO-INVENT-LOT-01 block LLM guess.
2. MOQ as lot
MOQ-REROUTE-01 threshold € not SKU lot.
3. Execute order edit bot
Rule 5 handoff agents only.
4. Route dup as qty
Rule 4 DUP-REROUTE two orders.
5. Waive lot bot promise
Policy exception agents manager only.
6. Skip units_per_unit
TPL-CARTQTYBOT-PACK must cite count.
7. Blame client tone
Empathy + guide not "you should have read".
8. Ignore mobile context
bot_cartqty_mobile_plusminus branch touch UX.
9. Saved cart as lot bug
Restore #438 verify rules first.
10. Empty handoff post_order
Rule 7 payload sku qty order fulfillment.
11. Skip valid qty suggest
Rule 6 TPL-CARTQTYBOT-VALID-NEXT required.
12. Skip /pages/cart-quantity
Rule 8 link once.
13. Theme bug reproducible
+/- bug confirmed : product ticket escalate not repeat TPL-CARTQTYBOT-MOBILE only.
14. Compare two SKUs lot
Client asks product A lot 6 vs B lot 12 : CBQ-3 lookup both SKUs separate TPL each grounded.
How does Qstomy implement CARTQTYBOT?
Qstomy on Shopify runs CARTQTYBOT: bot_cartqty_* classifier, CARTQTY-MAP #474 lookup, product metafields API, valid qty calculator, MOQ dup reroute gates, handoff order edit payload.
Qstomy cartqty bot capabilities
cartqty_intent_classifier: 12 bot_cartqty intents
cartqty_map_bot_lookup: lot step units max
valid_qty_calculator: next lot multiple
invent_lot_guard: block ungrounded rules
moq_dup_rerouter: branch #476 #473
order_edit_handoff: post-order payload
Pipeline #475 #474 #476
#475 bot tier 1 qty explain. #474 agents post-order. #476 MOQ wholesale when live reroute.
Calculated DTC scenario
Food lots of 6, 38 cartqty tickets/month, invent lot uncalibrated bot baseline.
After CARTQTYBOT-SUP + Qstomy: cartqty_bot_auto_resolve 81%, cartqty_bot_invent_lot 0, cartqty_bot_pre_purchase_save +12%, cartqty_bot_csat 4.5/5.

Conversion AI Governance
CBQ-8 logs feed AI governance (#124) monthly cartqty_bot guardrail audit.
Weekly cartqty bot guardrail audit
Sample 25 sessions regex lot_size not in map responses zero tolerance.
Cart validation webhook integration
Cart API reject invalid qty → webhook bot_cartqty_cannot_add_qty session with sku qty_requested prefilled.
PDP metafield sync monitor
Alert when Shopify metafield lot_size diverges from CARTQTY-MAP row: block bot responses SKU until ops reconcile single source truth.
What checklist is needed to deploy CARTQTYBOT?
Checklist CARTQTYBOT (12 steps)
Sync CARTQTY-MAP #474 JSON into bot RAG
Draft policy CARTQTYBOT-SUP 8 rules
Deploy 12 intents bot_cartqty_* classifier
Implement CBQ-1 to CBQ-8 + guardrails
Shopify product metafields read-only CBQ-3
Valid qty calculator lot multiple logic
TPL-CARTQTYBOT-* + /pages/cart-quantity corpus
MOQ dup reroute rules CBQ-5
Test 8 scenarios: lot 6 qty 3, pack 12, step 5, max, mobile +/-, post order handoff, moq reroute, dup reroute

Red team invent lot moq confusion quarterly
Summary
#475 = bot qty cart tier 1, no execute edit
CARTQTY-MAP #474: shared corpus
NO-INVENT-LOT: API grounded
MOQ reroute: not lot macro
KPI cartqty_bot_invent_lot: target 0
FAQ
Does the bot modify orders?
No. Handoff agents #474 CQ-7. Bot explain pre-purchase guide.
Difference with #474?
#474 agents post-order edit. #475 bot classify explain handoff.
Difference with MOQ #476?
MOQ = total order threshold. Bot reroute. Cartqty = SKU lot qty.
Qty 3 lot 6?
TPL-CARTQTYBOT-VALID-NEXT suggest 6 next valid.
1 qty = how many pieces?
TPL-CARTQTYBOT-PACK units_per_unit CARTQTY-MAP.
Going further
This week: import CARTQTY-MAP into bot RAG, deploy bot_cartqty_* classifier, activate NO-INVENT-LOT guardrail, configure valid qty calculator, PDP chip T1, test 8 scenarios staging, launch dashboard cartqty_bot_invent_lot zero tolerance.
Share this guide #475 with product and bot ops: a suggested grounded valid qty is worth ten invented LLM answers about the lot, a clean MOQ reroute is worth five "impossible to add 3 to cart" tickets on misunderstood wholesale threshold.
Go-live test matrix
8 scenarios: lot qty 3 valid next, pack units, step 5, max promo, mobile +/-, post order handoff, moq reroute, dup reroute.
CARTQTYBOT internal documentation
Wiki ops: intents → templates → reroute MOQ dup → handoff triggers, CARTQTY-MAP owner #474, guardrail owner bot ops.
Quarterly MOQ corpus sync
When #476 MOQ live update CBQ-5 reroute corpus and MOQ-REROUTE-01 templates from MOQ-MAP not placeholder.
Runbook handoff order edit
Agents receive sku lot_size qty_requested order_id fulfillment in Gorgias payload without re-explaining lot rules already covered by bot.
