Public site + profile
Joiners
Find or request a deal, spend points, pay, track, chat. The crowd they join is the reason the price moves.
Case Study
GroupBuy — we built the deal engine that drops the price as Bangladesh joins in.
Live at groupbuy.bdshop.com. Buy together, save more — a joiner reserves a seat, the tier unlocks, the desk approves, four rails collect, Steadfast delivers, and club points come back. We shipped the public deals, the points loop, gpanel, merge logistics, and EcoSupport so a group buy is a product people finish.

Why this build
We designed GroupBuy around how people here already buy together.
A standard cart locks a price at checkout. Group buying waits for a crowd, then unlocks wholesale. The joiner, the partner who listed the SKU, and the desk that packs Steadfast all need the same ticket. That is the product we shipped.
Sell with us
Partners
Offer a SKU, get attributions on the deal card, ride the group instead of running a lonely Facebook ad.
gpanel + EcoSupport
The desk
Approve, collect, merge, book Steadfast, answer chat. Roles and HR sit behind the same brand.

Hero deals, hot deals, categories, voice search. If the SKU is missing, Requested Deals writes a public ask the buying desk can schedule.

ReservedThe crowd writes the price
Ten club points reserve a seat. Tiers drop on participant count or quantity. Countdown, attributions, and “you’ve joined” sit on one deal page.
Pay
PaidApprove, then collect
gpanel approves participation. The order takes bKash, SSLCommerz, bank receipt, or Bangla QR — full, remaining, or partial. SMS can match a transfer.
Ship
DeliveredMerge, book Steadfast, reward
Combine or merge for one invoice. Bulk shipment + webhook. Delivered returns 30 club points. Support already sees the same order.

How the desk helps
Landing, deals, payments, points, Steadfast — one scroll.
01 · Landing
How the homepage helps a stranger become a joiner
Buy Together, Save More is the promise. Hero deal, hot grid, how-it-works, reviews, and a notify list. Login, Sign up, Request Deals, Sell with us, and Support sit in the same chrome — a Facebook shopper can join without a briefing.
- Hero + hot deals with live participant / quantity progress
- Voice search and deal cards on the same catalog
- Support chat opens on the public site, not a separate inbox
02 · Deal page
How a deal page makes the crowd visible
Countdown, original vs group price, participant or quantity tiers, attributions, and the join button. Once approved, the same screen shows the order number and status. More people really does mean a better price — the math is on the page.
- Tiers by headcount or by units, not a fake strikethrough
- Join costs 10 club points so empty seats stay honest
- Deal Features come from the attributions desk, not hard-coded copy
03 · Payments
How four rails help the order actually close
Bangladesh does not pay one way. bKash, SSLCommerz cards, bank transfer above ৳5,000 with receipt OCR, and Bangla QR. Partial and remaining payments stay on the order. Fees are settings, not a surprise on the invoice.
- QR and bank queues live in gpanel beside All Payments
- SMS verifier can match a transfer to the ticket
- Waiting-for-due-payment is a first-class status
04 · Club points
How points keep the next deal warm
New members start with 100 points. Joining spends 10. Delivery returns 30. The deal card is a collectible on the profile — loyalty is a ledger, not a rumour in a group chat.
- Reasons logged: join, payment, delivered, revoked, adjustment
- Insufficient points block a join with a clear message
- Profile shows the balance the next deal will spend
05 · gpanel
How the admin desk runs a live group buy
Deals, schedule, categories, attributions, requested deals, partner offers, offer requests. Participants: current pendings and bulk quick-approve. The floor is a queue — today’s catch of joiners is not mixed with next week’s booking.
- Clone a deal for the next window instead of rebuilding it
- Requested Deals turn public asks into a scheduled SKU
- Roles gate dashboard, payments, and logistics separately
06 · Orders + Steadfast
How reporting and last mile stay on one book
All orders, bulk invoice, CSV, product requisitions. Combine and merge so one customer, many deals, one parcel. Bulk shipment books Steadfast; webhooks write the status back. Month-end is a filter.
- Merged invoice for the combined ticket
- Steadfast updates and webhook as automations
- Analytics sit next to the same statuses the site shows
07 · Support + partners
How chat and Sell with us feed the same factory
Live support and tickets push into EcoSupport at support.bdshop.com. Sell with us and partner offers give suppliers a door. The chat already knows the customer and the order — a joiner does not re-type the story.
- Support API for customers, products, orders, notes
- Partner offers and attributions on the deal page
- HR desk for the team that runs the queue

How it works
Three public steps. The desk finishes the rest.
01
Find a deal
Browse curated products with a visible group discount.
02
Join the group
Reserve a seat. Help the deal hit its participant or quantity target.
03
Save together
When the target lands, everyone pays the unlocked group price.
01 · Deep dive
A deal is a living price the crowd can unlock
Each deal holds original price, group price, end date, hero flag, and tiers of type participant or quantity. Progress is current joiners and current units. The homepage cache refreshes that math so the hot grid stays honest under traffic.
02 · Deep dive
Payments that match how people here actually pay
bKash callback, SSLCommerz IPN, bank receipt transcription, Bangla QR, SMS match. Partial payment settings and remaining-due status live on the order. Bank is offered from ৳5,000 so small tickets stay on mobile money.
03 · Deep dive
Merge and combine for a real last mile
One customer can sit in several deals. Combine orders, approve a merge request, print one merged invoice, then bulk-book Steadfast. The parcel is one story. Statuses run pending → due → packaging → courier → delivered — plus merged.
04 · Deep dive
Support already knows the ticket
The widget opens Group Buy Support. API credentials sync deals and stock to EcoSupport. Agents see the customer, the product, and the order notes without a second login culture.
05 · Deep dive
Sell with us keeps the catalog growing
Requested Deals is the public wishlist. Partner offers and offer requests are the supplier door. Attributions stamp warranty, brand, or bundle facts onto the deal the crowd is already watching.
