"I ordered size M on pre-order, but the site now shows S available immediately." "My color is delayed while the other is shipped." "Can I change my variant without canceling?" Three tickets where an ill-explained pre-order by variant creates confusion, delays, and chargebacks.
The pre-order variant availability support covers different ETAs by size, color or format, mixed pre-order plus in-stock inventory, variant changes, and split carts. This is distinct from global pre-order (#187): here, we deal with SKU variant granularity and heterogeneous lead times.
This guide #551 covers policy VARPRE-SUP, flows VP-1 to VP-8, and the matrix VARPRE-MAP. It completes pre-order and variants. Paired with customer service of the future VARPRE bot (#552).
Summary
Why does pre-ordering by variant generate tickets?
A product can have size S in stock and M on July pre-order. The customer reads "available" on the product page without seeing the selected variant. The agent quotes a global product date instead of the ETA of the ordered variant.
Five typical frictions
Variant ETA: M lead time ≠ L lead time on the same PDP
Mixed stock: one color ships now, another is pre-order
Variant change: swapping size/color before production
Split cart: line items with different fulfillment statuses
PDP display: pre-order badge missing on the affected variant
Shopify points out that availability is expressed at the variant level, not just the parent product (Shopify, variants 2026). Customer service must quote the ETA per ordered SKU.
VARPRE #551 vs pre-order #187, variants and bot #552
Five contents, five levels of stock granularity.
Quick matrix
#551 VARPRE: ETA availability by color size variant
#187 preorder: global preorder cancellation delay compensation
Variant errors: checkout variant selection errors
Split shipment: partial shipments multi-status
#552 VARPREbot: variant ETA bot grounded
#187 = general preorder policy. #551 = zoom stock ETA by variant and SKU change before ship.
Which varpre_* typologies should be classified?
Eight variant preorder ticket scenarios.
Eight varpre typologies
varpre_eta_variant: when will my size/color be shipped
varpre_stock_mixed: stock vs preorder variant of the same product
varpre_swap_variant: change size/color before shipping
varpre_cancel_one_line: cancel one variant and keep the others
varpre_pdp_mismatch: site says available but preorder at checkout
varpre_delay_one_variant: delay on one variant only
varpre_split_shipment: one variant shipped, the other pending
varpre_availability_check: which variant is available when
Tags: varpre, preorder_variant, variant_eta. VARPRE-MAP-GROUNDED: ETA from variant map, never parent product date.
How to structure the VARPRE-MAP matrix?
The VARPRE-MAP matrix documents availability by SKU variant for agents and future bot #552.
VARPRE-MAP Columns
variant_sku: size color size SKU
availability_type: in_stock preorder backorder sold_out
eta_ship_date: variant ISO shipping date
eta_window: week range of if uncertain
swap_allowed: yes no cutoff date
cancel_line_allowed: cancellation of single line policy
pdp_badge: PDP checkout variant badge text
bot_intent_map: bot_varpre_* #552 mapping

VARPRE-SUP six-rule policy
Six rules supporting pre-order variants.
VARPRE-MAP-GROUNDED: ETA quotes ordered variant only
NO-PARENT-ETA: never global product date if variant differs
SWAP-CUTOFF: variant change before cutoff map
SPLIT-TRANSPARENT: explicit status per line item
DELAY-VARIANT-SCOPE: announced delay affects ordered variant only
MIXED-STOCK-CLEAR: distinguish immediate stock vs preorder
Flow VARPRE VP-1 to VP-8
Flow agent eight steps pre-order variant.
VP-1 Intake: varpre_* intent + order line variant
VP-2 Line lookup: SKU variant ordered fulfillment status
VP-3 VARPRE-MAP: availability eta swap cancel rules
VP-4 Classify: eta swap delay split availability
VP-5 Respond: macro VARPRE grounded variant SKU
VP-6 Swap execute: SWAP-CUTOFF edit line if authorized
VP-7 Split notify: partial tracking other lines
VP-8 Close: tag varpre_resolved variant_sku
SLA: varpre_eta_variant answered with eta_ship_date map and pdp_badge in one interaction.
Essential VARPRE macros
Four macro agents.
VARPRE-ETA-01
"Variant [variant_label] SKU [sku]: preorder, estimated shipping [eta_ship_date]. Other variants: [availability_summary map]. Order #[order_num] status [fulfillment_line]."
VARPRE-SWAP-01
"Change to [new_variant]: [authorized before [swap_cutoff] / denied production started]. [If authorized: confirmed, new ETA [new_eta].] [If denied: line cancellation or wait according to policy #187]."
VARPRE-SPLIT-01
"Order #[order_num] partial shipment: [variant_shipped] shipped [tracking]. [variant_preorder] preorder, ship [eta_ship_date]. Two separate notifications."
VARPRE-DELAY-01
"Delay variant [variant_label]: new ETA [new_eta], reason [reason]. Other lines unaffected. Options: wait, swap if [swap_allowed], cancel line."
Edge cases: mixed cart, color, and made-to-order
Five cases outside the standard ETA macro.
Mixed preorder stock cart: #187 mixed cart policy
Pending color: variant color expectation
Made-to-order variant: unit manufacturing post-purchase
Limited preorder: preorder quota per variant
Split shipment bot: multi-status line items bot
Made-to-order variant: workshop production ETA, not product launch date. Distinct tag varpre vs mto.
Essential KPI variants
Five VARPRE steering metrics.
varpre_ticket_rate: variant tickets / preorder SKU orders
varpre_eta_accuracy: % variant ETA respected vs map
varpre_swap_success: variant changes before cutoff
varpre_pdp_mismatch_rate: display vs checkout tickets
varpre_split_clarity: partial variant shipment CSAT
Target: varpre_eta_accuracy higher than 90% on multi-variant preorder drop cohorts.
VARPRE anti-patterns
Five common mistakes.
Parent product ETA: NO-PARENT-ETA
Swap after cutoff: SWAP-CUTOFF
Global order status: SPLIT-TRANSPARENT line item
Unscoped variant delay: DELAY-VARIANT-SCOPE
Confusing stock and preorder: MIXED-STOCK-CLEAR
