Evidence beside the buy button.
Qomero's ARVUMA sells landscape grass seed, aquatic plants and plant nutrition. Its plant shop is reusable by another business.
Status: LIVE

Context
ARVUMA is a Qomero business selling landscape grass seed, aquatic plants and plant nutrition.
Problem
Customers bought in bits across channels. Orders never came together, spend per customer was unknown, and there wasn't enough data to resell or upsell.
Published scope
The ARVUMA web shop.
What we did
Buyers filter products by fit for each of the 63 provinces; an agent checks the data against official weather, season and geological sources. Germination evidence and a plainly written warranty sit beside the buy button.
Verified result
VietFarmAsia bought a one-year licence to ARVUMA's code and runs vietfarmasia.com on it.
Limits
Orders and conversion are not published.
Before the build
Seed and plant buyers need to know what grows where they live, before they pay.
Customers bought in small lots across many channels. ARVUMA could not bring orders together, could not see what each customer spent in total, and lacked the data to plan reselling or upselling.
Why off-the-shelf failed
ARVUMA looked at the popular shop builders before building its own.
What we decided
Evidence beside the buy button. Germination rates and warranty terms sit next to it, not on a policy page.
Each seed has its own germination verification page.
The warranty is written in plain language.
Built around selling plants, not one brand. That is why VietFarmAsia could use the code without a rewrite.
Found through search. SEO with a sitemap covering the products.
Architecture
Drawn from documented technologies; data flows are not inferred.
ARVUMA
Stack: HTML, JavaScript, Vercel. One codebase runs ARVUMA's shop and vietfarmasia.com.
Suitability data for all 63 provinces: an agent checks weather and growing-season data and collects geological information from official sources.
What the system handles
- A buyer filters products by how well they suit their province, across all 63.
- Before buying, the buyer checks germination evidence and warranty terms on the product page.
- VietFarmAsia runs its own site on the same code, with no rewrite.
Result
- VietFarmAsia bought a one-year licence to ARVUMA's code and runs vietfarmasia.com on it.
