Great product, fast delivery.
Problems we solve
- 01
Reliance on big online stores
Fees, rules, and customer data sit with someone else, making it hard to build a direct relationship with buyers.
- 02
Stock out of sync
An item sells on one channel after it has already run out on another.
- 03
Payments checked by hand
Admins match bank statements to orders one by one, and things slip through.
- 04
Orders and shipping in disarray
Shipping rates, tracking numbers, and order status are handled separately.

In short
Hailmary Studio builds single-brand online stores, multi-vendor online stores, and point-of-sale apps for physical shops. Payments through payment gateways, QRIS, and virtual accounts are recorded and reconciled automatically. Shipping rates come straight from connected couriers, and online stock always matches the stock at the till. Managers get an admin panel for orders and sales reports, and in a multi-vendor store each seller has their own panel with configurable commissions and payouts. Small businesses can start with a simpler small-business plan.
FAQ
Does it support multiple sellers?
Yes. A multi-vendor store includes a seller panel where each seller manages their own products and orders, commission settings, and seller payouts. The store operator keeps an admin panel to oversee all sellers, orders, and sales reports in one place.
Which payment methods are supported?
We integrate payment gateways, QRIS, virtual accounts, and invoicing. Incoming payments are matched to orders automatically, so order status updates without checking bank statements by hand. The final options depend on the payment provider you use, and we help connect it.
Can it connect to a physical store’s till?
Yes. The point-of-sale app for your physical shop shares stock data with the online store. Every sale at the till or online updates stock in both places, so customers can’t order online an item that has already sold out in the shop. Sales reports from both channels are combined too.
Is there an option for small businesses?
Yes. The small-business plans offer a simpler scope: a store that looks right on a phone, a product catalog, WhatsApp orders, and management from your phone. There are three plans for each stage of growth, and you can upgrade as orders grow. Details are on the small-business online store page.
