MANIYARI
A multi-vendor marketplace that gets small sellers online without an IT department — shops, catalogs, payments and orders from one system that stays out of the way.
ORDER STATE MACHINE — EVERY PURCHASE WALKS THIS PATH
PAYMENT FAILS → ORDER HELD → RETRY OR RELEASE STOCK — INVENTORY NEVER LIES
01 — WARP
What had to be true first
Maniyari's constraint was its users: local vendors with no technical staff, moving online for the first time. The warp was a vendor model simple enough to onboard in minutes but structured enough to keep a marketplace honest — shops, catalogs, inventory and orders as first-class records with clear ownership.
02 — WEFT
What we wove through it
Onto it went the marketplace: vendor onboarding and shop management, product listing with category and inventory control, order tracking on both sides of the sale, secure payment integration, and search and filtering that makes a many-vendor catalog feel like one shop. The admin dashboard runs the whole bazaar.
03 — BEAT
How it was pressed tight
Marketplace code fails at the seams — payment confirmed but stock gone, orders split across vendors, a seller editing a product mid-purchase. Those seams got the review and the tests: inventory is authoritative, payment states drive order states, and no order can exist in a state the machine doesn't name.
04 — WEAR
Life in production
Maniyari operates in production with vendors selling who had never sold online before. Sellers manage products, orders and payments from one screen, buyers get a coherent storefront, and the platform scales by adding vendors, not engineers.
