Listing helpers — templates & photo checklist

Listing templates

Photo checklist

Good photos = faster sales and higher prices. Aim for 6–10 shots per item.

Lighting trick: shoot near a window during the day, item on a clean neutral surface (white sheet, wood floor). Never use the flash.

Workflow & reference — weekly rhythm, discount schedule, fees

Weekly rhythm

Discount schedule

If an item hasn't sold within the window, drop the price. Marketplaces boost items when you relist or lower.

Days listed	Action	Why
0–14	Hold target price	Most organic views happen in first 2 weeks.
15–30	Drop 10%, refresh photos or title	Algorithms treat a price cut as a relist signal.
31–60	Drop 20–25%, cross-post elsewhere	You're in stale territory. Break the pattern.
60+	Go to minimum, or bundle with similar items	Capital stuck in stale inventory is worse than a small margin.
90+	Donate for the tax receipt	Storage and mental load aren't free.

What to buy

Buy	Why
Known brands (Le Creuset, Patagonia, Pyrex, Lego, Coach, Stanley)	Named brands have comps. Comps = confidence.
Items with sold comps ≥ 3× your cost	Gives margin for fees, time, returns, bad photos.
Small, light, shippable items	Shipping ≤ $10 keeps margins healthy.
Large items with local demand (furniture, lamps)	Cash + pickup on FB Marketplace = zero fees.

Skip: fragile glass you can't ship, generic fast-fashion, items with broken or missing parts (unless Lego, by weight/lot).

Platform fees

Fee excludes optional promoted-listing / seller-ads fees. Payment processing is bundled in for the marketplaces that charge it.

How do I calculate my reselling profit?

Net profit = Sale price − Platform fees − Shipping cost − Item cost. Selling a $75 item on Poshmark with an $8 cost: $75 − $15 (20% fee) − $0 shipping − $8 = $52 net profit, a 650% ROI.

When should I discount a resale item that isn't selling?

Hold your price for 14 days. Drop 10% at day 15–30, 20–25% at day 31–60, and go to your minimum or bundle after 60 days. After 90 days, donate for the tax receipt — stale inventory and storage costs aren't free.
