One loop across the four channels sellers actually run.
Tideline watches Amazon, Shopify, Meta, and TikTok through the same overnight loop — drift watcher, low-stock reorders, and brand-voice inbox replies — with the integration set scoped to whatever each channel actually needs.
What Tideline handles on each channel.
Each row is a channel. Each column is a surface Tideline watches. Every cell points back to the same overnight loop — only the wording shifts per channel.

One concrete walkthrough each.
Same loop, different storefronts — the agent composes one paused-campaign, reorder PO, or brand-voice draft per channel and parks it for review.
- Amazon
Sponsored Products drift on “WINTER BOOT // MID // META — top creatives” past the 1.4× CPA guardrail — paused at 8 minutes past midnight, parked in the Rules queue for the planner to review before standup.
- Shopify
OAK BARSTOOL (WK-104) drops to 4 days of cover at NJ-1 overnight — restock P.O. drafted against BenchForm lead-time, waiting in Rules for the buyer to approve.
- Meta
Devon A.’s DM on the cream wool hat restock lands at 6:14 a.m. — the agent composes a reply in the trained voice (“Still end of August — pulling the latest forecast from the buyer”), parked in Inbox with the SLA clock paused pending approval.
- TikTok
Kiri P.’s TikTok DM asking if the natural linen tote is restocking in May lands overnight — brand-voice draft composed against three past replies, queued in Inbox with a carrier ETA check on the TikTok Shop order line.

Map the loop to the channels you actually run.
Pricing scales with the stores you connect and the reply volume you handle — for a single Amazon store, a Shopify-first brand, or a Meta + TikTok DTC stack. The help center answers the wiring questions.
