Open Quotation (OQ) is Mbizmarket’s request-for-quotation and negotiation flow for government agencies and state-owned enterprises, with LKPP procurement rules built right into the interface.
Real screen from the OQ design file. All vendor and user data is fictional.
Buyers compared quotes in spreadsheets and chat. A new rule requires at least two quotes, and breaking it usually only showed up at audit.
Put the rule inside the UI, swapped a wide table for ranked uniform cards, and kept buyers and vendors in one shared shell.
In a walkthrough, shortlisting 10 quotes dropped from about 2 hours to about 35 minutes, and the two-quote rule can’t be broken by accident.
to shortlist 10 quotes and get to negotiation, right on the Compare screen.
of pilot rounds got fewer than 2 valid quotes and were cancelled by the system, so none of them reached an audit as a broken round.
more small businesses (UMK) quoting per round in the pilot, because every vendor gets the same invite, spec and rules.
Mbizmarket is a B2B e-procurement marketplace used by Indonesian government agencies and state-owned enterprises. OQ lets a buyer invite several vendors to quote on the same request, compare the offers, negotiate, and issue a purchase order, all without leaving the platform.
Agencies and SOEs. They create the request and pick the winner.
Suppliers, including small businesses (UMK). They send and revise quotes.
The buyer’s boss. Signs off before the PO goes out.
Before OQ, price comparisons lived in spreadsheets and chat, completely outside the audit trail. A new regulation requires at least two quotes, and with fewer the round has to be cancelled. Buyers also juggle price, local content and delivery time at once, often across many items. And all of it had to slot into a live product without breaking its visual system.
Set by LKPP Decree 93/2025. Until now, violations usually surfaced at audit, after the PO was already out.
Buyers weigh price, local content (TKDN) and delivery time together, then may renegotiate item by item.
Header, sidebar, buttons and status labels had to match every other page. Buyers shouldn’t feel they switched apps, and engineers should reuse what exists.
Agencies get the best price with an audit-ready trail, vendors get a fair shot, and Mbizmarket keeps project deals on the platform.
A normal UX process, except every step got checked against procurement rules.
I mapped how buyers and vendors worked before, marking what was painful and what was risky under the rules.
Buyer and vendor flows, including the unhappy paths, like a round with fewer than two quotes.
From wireframes to UI on top of the live design system, then into a clickable prototype.
Walkthroughs with PM and QA, failure scenarios checked, fixes made before handoff.
“If I did it again, I’d bring vendors in much earlier.”
I designed the buyer side first. The vendor flow had to be reworked once we saw how small vendors actually send their quotes.
