Quartermast vs Sidekick.
A helpdesk surface in front of your Shopify inbox.
Great ticket UI. Leaves inventory, ad ROAS, and the morning P&L to whoever wakes up first.
Scoreboard
Sidekick
1/ 5
4 gaps
Quartermast
5/ 5
Full coverage · overnight loop
Pillar · Inventory
Inventory.
Velocity, on-hand, lead time, refund rate — every SKU.
Quartermast · overnight
Watches every SKU; restocks from your supplier the moment cover drops below your floor.
Sidekick
No inventory monitoring — stockouts surface only after an order fails.
What that leaves uncovered
No monitoring, no threshold, no reorder loop. A stockout takes the listing offline before anyone sees the alert.
Pillar · Ad ROAS
Ad ROAS.
Per-set spend, CAC drift, creative fatigue, ROAS floor.
Quartermast · overnight
Cyclic pause-then-resume on ROAS-floor breaches; swaps creative; one decision queue, every ad account.
Sidekick
No ad-account connection; ad spend never reaches the operator loop.
What that leaves uncovered
No ROAS floor, no cyclic pause, no creative swap. Spend keeps draining until someone reads the dashboard.
Pillar · Support tickets
Support tickets.
Returns, escalations, drafted replies in your voice.
Quartermast · overnight
Drafts the reply straight from your policy; you ship it from the digest in one click.
Sidekick
Helpdesk UI, macros, SLAs — really good.
What that leaves uncovered
Strong helpdesk surface — but no inbox digest at 06:30 and no automatic recall of related incidents.
Pillar · Reviews
Reviews.
New ratings, replies, pattern drift on the products you sell.
Quartermast · overnight
Clusters 1-stars per SKU, cross-checks the last 30 shipments for defects, alerts with evidence before it spreads.
Sidekick
Pulls review sentiment into the ticket thread, but does not act on it.
What that leaves uncovered
The signal surfaces in their UI; nobody clusters it, nobody alerts the merchant with shipment-level evidence.
Pillar · Morning digest
Morning digest.
One daily P&L: what sold, what bled, what got fixed overnight.
Quartermast · overnight
06:30 morning P&L with net, ad spend, refunds, low-stock count — every fix linked underneath.
Sidekick
No morning P&L. No daily summary of what sold or what bled.
What that leaves uncovered
No daily P&L. The morning summary is the merchant reading five dashboards and writing three emails.
§ Next — Try the operator
If Sidekick left the night shift on you, hand it over.
Connect your store, set the ROAS floor and the low-stock threshold, ship the 06:30 P&L on day one. The decisions Sidekickdoesn't make for you, the Quartermast operator makes.
