Kindlebit
Product Engineering and QAPublicly listed capability

Build the marketplace or enterprise portal where vendors, buyers and staff do business on one set of rules.

We engineer multi role platforms with vendor onboarding, catalogues, transactions, approvals and integrations, encoding your business rules so the platform enforces them instead of people.

Problems this service is built to solve

These are situations we expect buyers to recognise. Each one states why it happens, what it costs and how we would approach it.

Complex vendor and buyer workflows

A parts marketplace needs vendors to list inventory, buyers to request quotes and the operator to approve new vendors and resolve disputes. The first version handled orders but handled everything else in email.

Why it happens
Marketplaces involve at least three parties with different goals, and the happy path is only a fraction of the flows.
What it costs
Operations staff become the workflow engine, and trust issues slow growth.
How we approach it
We model each party's journeys, including disputes, returns and exceptions, and implement them as explicit states with notifications and permissions.
What to measure
Share of transactions completed without operator intervention, dispute resolution time and vendor activation rate.

Enterprise data silos

A distributor's customer portal needs pricing from the ERP, stock from the warehouse system and account history from the CRM. Each answer comes from a different place and none agree.

Why it happens
Systems were never integrated, and each team maintains its own copy.
What it costs
Wrong prices quoted, customers calling to confirm availability and staff reconciling by hand.
How we approach it
We define systems of record, integrate through APIs and events, cache with clear freshness rules and show data provenance in the interface.
What to measure
Data freshness, mismatches between portal and source systems and calls to confirm information.

Manual administration

Onboarding a new vendor takes a week of document checks, account creation and catalogue upload by a back office team.

Why it happens
Admin tasks were not designed as product features.
What it costs
Onboarding limits growth and creates errors and delays.
How we approach it
We build self service onboarding with document capture, verification workflows and bulk catalogue import with validation, leaving staff to handle exceptions.
What to measure
Vendor onboarding time, staff hours per vendor and error rate at import.

Complicated business rules

Pricing depends on customer tier, contract, volume, region and promotions, with exceptions agreed by sales. The rules live in a spreadsheet and three people's heads.

Why it happens
Rules grew over time and were never captured in a testable form.
What it costs
Inconsistent pricing, revenue leakage and long quote times.
How we approach it
We extract rules into a rules layer with versioning and test cases, replay historical orders to compare outcomes and give business users controlled ways to change them.
What to measure
Pricing discrepancies, time to produce a quote and rule changes shipped without engineering.

How we solve it

A delivery sequence built around architecture, testing, CI/CD and operational readiness.

Map parties and journeys

Document buyers, vendors, operators and the flows between them, including exceptions and disputes.

Define rules and data ownership

Capture pricing, approval and eligibility rules and decide which system owns each data item.

Design the platform

Define the domain model, roles, integrations, payments model and scale targets.

Build the core flows

Implement onboarding, listing, ordering, payment and fulfilment as tested workflows.

Integrate back office

Connect ERP, CRM, shipping and accounting with retries, monitoring and reconciliation.

Test business scenarios

Replay real orders, test rule edge cases, payments and refunds, and run security and load tests.

Launch and onboard

Launch with a controlled set of vendors and buyers, support them closely and fix friction.

Operate and extend

Monitor transactions and disputes, add features by data and maintain integrations.

Solution in action: Vendor onboarding and first order on a B2B parts marketplace

Reference Architecture An illustrative scenario. It describes how we would structure the work, not a delivered customer project.

Starting problem

The operator wants to add vendors faster without lowering quality.

Existing workflow

Vendors email documents, staff check them, create accounts and upload catalogues from spreadsheets.

Improved workflow

A vendor applies online, uploads documents which are captured and checked, staff review only flagged cases, the catalogue is imported with validation and the vendor goes live. A buyer places an order, payment is split between vendor and operator, and the ERP receives the invoice.

A vendor applies to join.

Systems involved

Marketplace app, document service, payment provider, ERP, shipping provider.

Data movement

Vendor documents, catalogue, orders, payments and invoices.

Human decisions

Operator staff approve vendors and handle disputes.

Automation opportunities

Document checks, import validation, order routing, settlement and invoicing.

Exception handling

Rejected documents return to the vendor with reasons. Disputes freeze settlement until resolved.

Resulting user experience

Vendors go live in days instead of weeks and buyers get accurate prices and availability.

Questions buyers ask

Can you build a platform from an idea?

Yes. We usually begin with discovery to define parties, flows and the first release, then build and launch in stages.

How do you handle payments between multiple parties?

We use payment providers that support split payments and payouts, such as Stripe Connect, and design refunds, disputes and reconciliation from the start.

Can the platform integrate with our ERP?

Usually, through APIs or files. We review the ERP's interfaces early and plan for data ownership, freshness and error handling.

How do you protect against fraud or low quality vendors?

Through verification at onboarding, ratings, monitoring and dispute workflows. The mix depends on your risk.

How long does it take?

A first release commonly takes four to eight months for a marketplace and varies for enterprise portals with integrations.

Can business users change rules?

Yes, within governed limits. Rules sit in configuration with approval and tests, so changes do not require deployments.
