"I had chosen Thursday 2pm-6pm, the delivery driver came on Friday." "How do I change my slot after ordering?" "No slots available at checkout, is this normal?" Three messages where a badly managed delivery slot generates disputes, negative reviews, and post-delivery chargebacks.
E-commerce delivery slot customer support covers checkout choice, post-purchase modification, slot confirmation, missed carrier slot, and associated fees, distinct from express cut-off or generic ETA.
This guide #427 covers policy SLOT-SUP, flow SLOT-FLOW, and KPI slot. Complements ETA and express. Distinct from express delivery (#338) and address change (#183): here, customer service playbook for chosen or modified delivery time windows.
Summary
Why do delivery slot tickets increase after purchase?
A delivery slot ticket concerns a time window chosen or expected by the customer that the carrier, the warehouse, or the checkout did not respect or make visible.
Five typical customer pain points
Missed slot: delivery outside the chosen window
Modification refused: changing the date/time post-order
No checkout slot: empty calendar, zip code excluded
Missing confirmation: customer no longer knows which slot was chosen
Slot fees: misunderstood premium surcharge
Shopify allows displaying estimated delivery dates and slot apps via checkout extensions and shipping profiles (Shopify, delivery dates 2026). Metapack estimates that 38-52% of fresh/furniture delivery disputes relate to an unfulfilled slot when the window is not confirmed by email (Metapack, scheduled delivery 2026).
Angle #427 vs related content
Express #338: cut-off next-day speed. #427 = chosen time window (e.g., Thursday 2pm-6pm).
Address change #183: post-order address. #427 = slot date/time, not street.
Perishables: mandatory slot fees. #427 = cross-functional view of all slot products.
Local delivery #429: future hyperlocal zone. #427 = general carrier scheduled slot.
Bot slots #428: future AI automation. #427 = customer service playbook for agents.
DTC Example
Gourmet grocery + furniture, 320 slot orders/month. Without SLOT-SUP: 41 slot tickets/month, slot_missed_rate 19%. After playbook: slot_ticket_rate -44%, slot_modify_sla_compliance 94%, slot_csat 4.2/5.
Cost of slot_missed dispute
1 untreated P1 fresh slot_missed = full refund + stock loss. SLOT-SUP ROI: auto fee refund + claim carrier recover 30-40% premium fees.
How does créneau differ from express and standard ETA?
Selected delivery window, express cut-off, and ETA range: three distinct delivery promises.
Promise Matrix → dominant ticket
Delivery slot #427: selected window, modify, missed
Express #338: tomorrow if before cut-off, no choice of time
Standard ETA: 3-5 business days, no window
Click & Collect: in-store pickup, no home delivery
Four SLOT-TYPES
slot_standard: 2 h window carrier (2pm-4pm)
slot_premium: evening/weekend, fee +5-15 €
slot_fresh: fresh/meat, mandatory slot
slot_oversize: 2-person furniture, telephone appointment
Delivery slot stack
Checkout app (Zapiet, Delivery Scheduler), TMS Onfleet/Bringg, carrier Colissimo slot, WMS export slot_id. Support reads slot_datetime, slot_status, carrier_confirm.
Promise #427
Policy SLOT-SUP, matrix SLOT-MAP, 12 slot_* typologies, flow SLOT-FLOW, SLOT-* macros, slot_* KPIs.
Checkout app vs native carrier
Zapiet/Delivery Scheduler vs Colissimo slot API. SLOT-MAP tick_app field for agent SL-4 lookup path.
Which slot_* typologies should be mapped?
Twelve delivery slot ticket typologies for consistent routing.
Twelve slot scenarios
slot_missed: delivery outside confirmed window
slot_modify_request: change date/time post-purchase
slot_not_available: no slot checkout PC
slot_confirm_missing: customer cannot find chosen slot
slot_fee_dispute: disputed premium surcharge
slot_carrier_no_show: slot passed, package absent
slot_partial_delivery: multi-package, different slots
slot_fresh_violation: fresh product delivered in wrong slot
slot_oversize_rdv: furniture, carrier call required
slot_address_conflict: address changed #183 + slot stale
slot_app_bug: checkout slot not exported WMS
slot_chargeback: threat of litigation missed slot
Helpdesk tags

Mining slot verbatims
90-day export "slot", "range", "2 pm", "courier did not come". Prioritize macros on top 3 real shop typologies.
Which SLOT-MAP matrix should be documented?
The SLOT-MAP slot matrix lists zones, windows, fees, and modifications.
SLOT-MAP Columns
slot_zone: ZIP ranges, countries, exclusions
slot_type: standard, premium, fresh, oversize
window_options: Mon-Fri 8am-8pm, Sat 9am-1pm
modify_deadline: Day-N before slot, before shipping
slot_fee: premium +X €, free shipping conditions
carrier: Colissimo, Chronopost, 3PL own fleet
missed_policy: refund fee, redelivery, partial
Example slot_fresh fees
slot_fresh_idf: mandatory slot Wed-Fri 8am-1pm, no Sunday delivery. Missed fresh → full refund + priority redelivery P1.
Example furniture slot_oversize
slot_oversize_fr: 4-hour window, phone appointment Day-2, modify until Day-3. Missed → carrier claim + partial refund fee per PART-REF #368.

How to write the SLOT-SUP policy in eight rules?
The SLOT-SUP slot policy governs modify, missed, and compensation.
Eight SLOT-SUP rules
Lookup slot_id first: order metafield, WMS, carrier confirmation before reply
Modify before ship only: if fulfillment unfulfilled + before modify_deadline
Missed verified: tracking timestamp vs slot window before compensation
Refund slot fee: if slot_missed confirmed, auto-refund premium fee
Fresh P1: slot_fresh_violation → full refund or same-day operations redelivery
No slot promise if unavailable: slot_not_available = explain zone, do not make up things
Address change sync: slot reset if #183 address change, re-offer slots
Carrier claim parallel: slot_missed → open carrier ticket + client update 24 h
Compensation matrix missed
Premium fee refund always. Product damage fresh → full refund. Standard missed 2h late → slot fee refund + 10 € store credit manager gesture for LTV > 200 €.
Modify impossible
If shipped or past deadline: uphold polite, offer carrier contact phone oversize. No false modify promise.
Self-service modify portal
Order status modify button reduces slot_modify_request tickets 35-50% if before deadline automated.
How to apply the SLOT-FLOW workflow in eight steps?
The SLOT-FLOW framework structures the delivery slot ticket processing.
Eight steps SL-1 to SL-8
SL-1 Lookup order: slot_id, slot_datetime, fulfillment status
SL-2 Classifier slot_*: section 3 typology
SL-3 Match SLOT-MAP: zone, type, modify_deadline, missed_policy
SL-4 Verify slot data: WMS export, carrier confirm, tracking
SL-5 Explain: macro SLOT-* grounded SL-4
SL-6 Decide: modify | uphold | refund fee | redelivery | carrier claim
SL-7 Execute: WMS reslot, Shopify partial refund, carrier ticket
SL-8 Document: slot_modify_count, claim_id, compensation amount
SL-4 slot_missed
Compare tracking delivered_at vs slot window. If outside window → SL-6 refund fee + carrier claim. If inside window client dispute → proof photo signature.
SL-6 slot_modify_request
If unfulfilled + before deadline → SL-7 WMS/carrier API reslot. If shipped → SLOT-MODIFY-DENY-01 explain + carrier phone oversize.
SL-4 slot_confirm_missing
Resend confirmation email from order metafield slot_display. Link order status page slot widget.
Carrier no_show today P1
slot_carrier_no_show window passed + no tracking: SL-6 redelivery priority + supervisor callback 2 h SLA.
Which SLOT-* macros and touchpoints should be configured?
Eight delivery slot agent macros and self-service touchpoints.
SLOT-CONFIRM-01 (slot confirmed)
« Delivery scheduled [day] [start time]-[end time] at [address]. Order #[X]. Modify before [deadline]: [portal link]. »
SLOT-MODIFY-OK-01 (slot modified)
« Slot updated: [new window date]. Email confirmation resent. Former slot [old] canceled. »
SLOT-MODIFY-DENY-01 (modification impossible)
« Parcel already shipped / deadline passed. Contact carrier [phone] for rescheduling. Tracking reference: [link]. »
SLOT-MISSED-01 (missed slot)
« We confirm delivery outside slot [window]. Refund of slot fees [X] € within 5-10 days. Carrier claim opened #[claim]. »
SLOT-UNAVAIL-01 (no slot available)
« Your PC [code]: standard delivery [ETA] without slot selection. Slot zones: [link /pages/delivery-slots]. »
Touchpoints
Checkout: slot calendar + fee visible before pay
Confirmation email: slot_display above fold
Order status: modify slot button if before deadline
/pages/delivery-slots FAQ SLOT-MAP
SMS Day-1 slot reminder + tracking link
SLOT-FRESH-P1 (cold chain fee violation)
« Fresh product delivered outside slot: full refund initiated. Do not consume the product. Priority reshipment if stock available. »
Which fresh, oversized, and multi-package cases should be processed?
Special slot cases require SLOT-MAP extensions and separate SLAs.
Fresh products slot_fresh
slot_fresh_violation: cold chain + strict window. Missed or wrong day → full refund P1 + ops discard stock log. Link perishables.
Furniture slot_oversize
slot_oversize_rdv: carrier calls D-2 confirm. Client absent → second delivery fee per SLOT-MAP or 1x free goodwill gesture.
Split shipment #356
slot_partial_delivery: package 1 Thursday slot, package 2 Friday. Explain split policy upfront checkout. Link split (#356).
Address + slot conflict #183
slot_address_conflict: address change invalidates slot zone. Re-offer slots new postal code or standard ETA.
Slot fees hidden fees
slot_fee_dispute: fee shown checkout line item. Link hidden fees if surprise.
Multi-addresses #409
Each address separate slot per line. Link multi-addresses (#409).
Prep time + slot alignment #395
MTO delay may invalidate chosen slot. Proactive reslot if ship date slips past slot. Link prep time article.
Which slot KPIs should be measured?
The delivery slot support KPIs drive modify SLA and missed rate.
Eight key metrics
slot_ticket_rate: slot tickets / slot orders
slot_missed_rate: slot_missed confirmed / slot orders
slot_modify_sla_compliance: modifies within 4 h / due P2
slot_modify_success_rate: modifies completed / modify requests
slot_fee_refund_rate: fee refunds / slot_missed
slot_carrier_claim_rate: claims opened / slot_missed
slot_fresh_incident_rate: fresh violations / fresh slot orders
slot_csat: satisfaction tag slot resolved
DTC Benchmark
slot_missed_rate < 8 % post SLOT-SUP, modify_sla > 92 %, fresh_incident < 2 %, slot_csat > 4.0/5.
Weekly dashboard
SLOT-TYPE breakdown, postal code zone with highest missed, carrier performance by partner.
Ops alert

On-time slot delivery ops KPI
Track delivered_at within window / slot orders. Correlate with carrier partner scorecard monthly.
Self-service modify convert KPI
Track portal modifies / slot_modify_request tickets. Target > 55 % self-service before agent.
What anti-patterns should be avoided on time slots?
Ten delivery slot support anti-patterns to ban.
1. Promising modify after dispatch
SL-4 fulfillment check mandatory. SLOT-MODIFY-DENY-01.
2. Compensation without tracking verification
SL-4 timestamp vs window. Friendly fraud slot_missed claims.
3. Confusing express #338
Express cut-off ≠ slot window. District router macros.
4. Address change without slot reset
Rule 7 #183 sync. Stale slot wrong zone.
5. Fresh missed treated as standard
Rule 5 P1 full refund. Not partial fee only.
6. Inventing slot for slot_not_available
Rule 6 SLOT-UNAVAIL-01 honest ETA standard.
7. Forgotten fee refund for slot_missed
Rule 4 auto premium fee refund always.
8. No slot confirmation email
slot_confirm_missing preventable. Confirmation above fold.
9. Skipping carrier claim
Rule 8 parallel claim. Recover cost 3PL.
10. Missing /pages/delivery-slots
Self-service modify gap. FAQ SLOT-MAP public.
11. Oversize without phone appointment
slot_oversize carrier no-show peak. Document phone D-2 process.
12. Conflating Wismo with slot query
"Where is my parcel" with slot tomorrow → cite SLOT-CONFIRM-01 + tracking, not generic WISMO only.

SLOT-MAP: zone → window → modify → missed
SLOT-FLOW: lookup → verify → modify/compensate
Missed = fee refund + carrier claim
KPI slot_missed_rate: target < 8%
FAQ
Difference with express #338?
#338 is next-day cut-off speed. #427 is chosen time window, e.g., Thursday 2pm-6pm.
Modify slot after order?
SLOT-MODIFY-OK-01 if unfulfilled + before SLOT-MAP deadline. Otherwise SLOT-MODIFY-DENY-01.
Missed slot, what to do?
SLOT-MISSED-01: verify tracking, refund fee, carrier claim.
No slot for my CP (postal code)?
SLOT-UNAVAIL-01: standard ETA + eligible zones on /pages/delivery-slots.
Does changing address impact slot?
slot_address_conflict: slot reset, re-offer new zone slots #183 sync.
Going further
This week: publish SLOT-MAP on /pages/delivery-slots, audit WMS slot export sync, create macros SLOT-CONFIRM-01 and SLOT-MISSED-01, train agents on SL-4 tracking verify.
Share this guide #427 with ops and support: a slot confirmed by email means a customer present for delivery, a forgotten slot means a one-star review the next day.
Express vs delivery slot at checkout?
Two distinct shipping options. Express #338 speed. Slot #427 window choice. PDP explains both.
Pre-peak fresh checklist
Before holidays: audit slot_fresh capacity, carrier backup fleet, +20% staffing on slot_missed P1 queue.
