TL;DR

• You only need five reliable syncs: Products, Inventory, Orders, Fulfillments, Settlements/Fees.
• Lock a single source of truth for inventory and reconcile payouts daily.
• Plan a 48-hour cutover and run a lightweight ops runbook (alerts + saved searches).
• Our SyncTok connector handles all five without middleware and is fully customizable.

Why “Cart-to-Cash” Matters

Revenue accuracy rarely dies from one big error—it leaks out through tiny desyncs: a price changed in Shopify but not in NetSuite, a refund posted in the channel but never re-valued in inventory, a fee that lands net-of-payout and hides in your AR. The cure is a lean, deterministic flow into NetSuite with reconciliation baked in. Decide where truth lives, make syncs predictable, and let exceptions surface themselves.

The Five Core Syncs

From there, everything runs through five small, predictable syncs—Products, Inventory, Orders, Fulfillments, and Settlements/Fees. Treat each as a contract: where the data originates, when it moves, and how it reconciles. Nail those contracts and month-end becomes a checklist. The sections below spell out the flow, key fields, classic failure modes, and a pattern that holds at scale.

Make sure to use NetSuite as the catalog and inventory master, let channels sell, and bring cash home through settlements. Stitch it with small, reliable syncs that run fast (near-real-time where it matters) and reconcile daily. Fancy is optional; predictable is not.

Products (NetSuite → Channel)

Flow: NetSuite is the master; publish to Shopify/TikTok on create & updates. Why: Prevent “channel-only” edits from forking your catalog and confusing pricing, tax, and reporting.

Your catalog is the foundation. Author once in NetSuite, push out to Shopify/TikTok, and stop channel-side edits from mutating SKUs, variants, and pricing. This keeps finance, tax, and reporting aligned with what customers actually see.

Key fields: SKU, Title, Price, Cost, Weight, HS Code, Tax Class, Variants/Options, Images. Common pitfalls: Duplicate SKUs, variant option drift, channel-side price edits. Pattern that works: Author in NetSuite, push immutable IDs, and block channel edits to price/SKU.

Inventory (NetSuite → Channel)

Flow: Publish on-hand available-to-promise by location in near-real-time, plus an overnight sweep. Why: Avoid overselling, especially when you ship from multiple sites or run preorders.

Inventory sync protects customer experience and gross margin. Publish available-to-promise, not everything in the building, and respect multi-location rules so channels know what can actually ship. Add an overnight sweep to fix any stragglers the real-time feed might miss.

Common pitfalls: Counting WIP/committed, ignoring backorders, no multi-location rules, API rate limits. Pattern that works: Publish ATP only, define location priority, and throttle updates to stay within channel limits.

Orders (Channel → NetSuite Sales Order)

When: On payment-authorization (Shopify) or order placed (TikTok). Payload: Customer, Ship-To, lines (SKU, qty, price, discounts), taxes, shipping, and the channel order ID.

Orders should land in NetSuite as clean, auditable Sales Orders with raw tax/discount data preserved. Decide when to import (auth vs. capture) based on your fulfillment flow and fraud posture, then normalize customers so “guest checkout” doesn’t explode your records.

Example: A cosmetics store maps all guest orders to a “Web Customer” record keyed by email hash, avoiding tens of thousands of near-duplicate customers while preserving contact-level reporting.

Common pitfalls: “Guest customer” explosion, discount/tax rounding differences. Pattern that works: Map guests to a Web Customer + email hash (or consolidate by email) and store raw tax/discount lines for auditability.

Fulfillments (NetSuite → Channel)

Flow: Item Fulfillment in NetSuite sends tracking back to the channel. Why: Customers get accurate tracking; the channel records delivery SLAs correctly.

Treat NetSuite as the system of record for shipping events. When warehouse ops complete Item Fulfillment, send tracking back to the channel quickly and consistently. Support partials and splits without confusing carriers or promise dates.

Common pitfalls: Partial shipments, split locations, carrier code mismatches. Pattern that works: Support multi-fulfillment per order, normalize carrier codes, and confirm on label print, not pick.

Settlements & Fees (Channel → NetSuite)

Flow: Import payout files; book sales, refunds, fees, tax, and shipping into NetSuite. Why: Your cash is net of fees; AR must still make sense.

Payouts arrive net of fees, but your books must still show gross sales, refunds, fees, tax, and shipping. Import settlement files daily, post fees to the right accounts, and auto-match to invoices so AR/GL tie out. Hold exceptions for human review rather than bending the rules.

Example: A DTC electronics brand books Shopify/TikTok fees to COGS vs. OpEx based on fee type, which tightened margin reporting and sped up month-end by two days.

Common pitfalls: Net-of-fee payments, chargebacks, timing gaps vs invoice date. Pattern that works: Daily settlement import, book fees to proper expense/COGS accounts, auto-match to invoices, and hold exceptions for review.

Returns & Exchanges Without Accounting Chaos

Use an RMA (Return Authorization) to approve returns before money or inventory moves. For a straight return, the flow is: create the RMA, receive the item for inspection, then issue a Credit Memo and a Customer Refund.

For an exchange, receive against the RMA and create an Exchange Sales Order to ship the replacement. During receipt, record the condition (sellable, refurb, scrap) and apply restock rules consistently; if the item isn’t sellable, revalue it so inventory and COGS stay honest. Map channel “return reasons” (e.g., wrong size, damaged) to NetSuite Return Reasonsto keep reports clean and spot trends.

Example: a footwear brand applies a 10% restock fee only to opened-but-sellable pairs, writes down scuffed pairs to refurb value, and uses reason codes to show that 60% of returns last month were size-related—fuel for a sizing guide update.

Inventory “Truth” & Backorders

Pick one source of truth and stick to it: NetSuite publishes availability everywhere.

If you run multiple locations, define which locations are sellable and in what priority (e.g., Storefront → DC East → DC West) so channels don’t drain safety stock from the wrong place.

Publish available-to-promise (ATP), not raw on-hand, and throttle updates to stay inside API limits. Allow backorders only when your PO or manufacturing lead times are dependable, and surface realistic promise datesback to the storefront (a simple custom field works) so customer service isn’t guessing.

Example: a cosmetics seller keeps boutiques off-channel to preserve shelf inventory, sells from DCs in priority order, and shows “Ships Aug 22–24” on items awaiting an inbound PO—cancels drop, CS tickets shrink, and month-end reconciles without surprises.

5) Settlement Reconciliation Patterns

Import payouts daily with separate lines for sales, refunds, fees, tax, shipping. Then choose how you apply cash:

• Invoice-level application – Clean AR aging and easier customer-level audits.
• Aggregate daily JE – Faster for very high volumes; rely more on saved searches for variance checks.

Either way, route exceptions to a “Settlement Mismatch” saved search and email alerts so finance can resolve before the month-end crush.

6) Shopify vs SuiteCommerce vs TikTok Shop (Decision Guide)

Shopify gets you to market fastest with a huge app ecosystem. Keep NetSuite as the system of record and lean on strong integration for products, inventory, orders, and payouts.

SuiteCommerce (SC/A) mirrors NetSuite’s data model and governance. If you already live in NetSuite for workflows, approvals, and reporting, SC/A reduces translation layers and edge-case handling.

TikTok Shop is a reach engine. To win, you must nail settlements and appeals, and avoid overselling through frequent inventory pushes and a strict exception process.

Rule of thumb: If your backbone is NetSuite workflows/reporting, SC/A wins. If your edge is brand velocity and growth marketing, Shopify + strong integration wins. TikTok remains an add-on storefront—treat it with strict inventory and settlement discipline.

7) 48-Hour Cutover Checklist

• T-14 days: Freeze SKU list; align tax & shipping rules; stage test orders.
• T-7 days: Full sandbox UAT covering 20 orders including discounts and refunds.
• T-48 hours:
• T+24 hours: Verify first payout import + bank match; run exception searches.

8) Ops Runbook (What to Watch Daily)

Saved Searches

• “Orders missing tax/discount lines (24h)”
• “Fulfilled in NS, not confirmed to channel (2h)”
• “Settlement lines unmatched to invoices (24h)”

Dashboard KPIs ATP for top 50 SKUs, refund rate, fee % of GMV, late shipment %.

Alerts API failures, rate-limit backoffs, carrier code mismatches.
