Learn about ProtocolHub

A product studio focused on finance, not generic software.

ProtocolHub is a Pakistan-based product company and holding structure dedicated to building a family of finance-native products. We think in ledgers, approvals, controls and risk from day one—then wrap that in a carefully crafted user experience.

Our first major product, Stack.pk, is a finance OS designed to sit at the center of your business: from chart of accounts and journals to payables, receivables, approvals, and reporting.

  • Built on a robust PostgreSQL schema with finance-grade semantics
  • Multi-tenant, multi-currency and API-first from the start
  • Designed for Pakistan’s regulatory and banking realities
Product studio + holding

ProtocolHub owns and operates multiple brands (starting with Stack.pk), giving us flexibility in how we structure partnerships and revenue.

Operator-driven roadmaps

We are building for real operators: founders, CFOs, finance leads, and teams that actually close books and approve payments.

Finance-native architecture

Double-entry ledgers, account classes, states and approvals designed deeply into the data model—not bolted on later.

Ecosystem mindset

ProtocolHub is built to spawn multiple products—each focused on a specific part of the finance stack but designed to work together.

Stack.pk — the finance OS from ProtocolHub

Stack.pk is the first product born inside ProtocolHub: a multi-tenant finance OS that combines ledgers, approvals, payments, and analytics into a single cohesive product.

What Stack.pk does

Stack.pk is opinionated about finance so you don’t have to reinvent the wheel:

  • Core ledger with account classes, states and orientations
  • Journals, payments, payables, receivables and fund flows
  • Approval chains, delegations and audit history
  • Imports, exports and connectors (sheets, CSV, future PSP/bank links)

Built with Laravel 12, Vue 3, PostgreSQL 16 and a carefully crafted component system so we can ship new finance modules quickly.

Multi-tenant by design

Secure separation of organizations and workspaces with fine-grained access and scoped views, ready for SaaS scale.

Perfect for firms managing multiple entities, or platforms embedding finance.

Approvals & delegations

Build approval chains for payments, journals and changes. Delegate powers, control limits and keep a clean audit trail for every decision.

Data-first reporting

Ledger and operational data is modeled to be analytics-friendly. Connect to data warehouses and build dashboards or ML models on top.

Import, export & sync

Generic import/export wizards that support CSV, Excel, and external sources, making it easier to move data into and out of Stack.pk.

Engaging with ProtocolHub

Our primary focus is on building and scaling our own products, but we selectively collaborate when it helps move the ecosystem forward and strengthens the ProtocolHub product graph.

1 · Discovery & context

We start with your finance context: current systems, compliance requirements, pain points and desired outcomes for your finance stack.

2 · Product fit & architecture

We explore how Stack.pk (and future ProtocolHub products) fit into your environment: data model, integration points, and rollout phases.

3 · Pilot & hardening

We run a focused pilot, close the feedback loop with real teams, and harden the product modules you need most.

4 · Scale & ecosystem

As we scale together, we evaluate additional ProtocolHub products (credit, APIs, analytics) that compound the value of your finance data.

Co-build initiatives

For select partners, we explore co-building modules that can become part of Stack.pk or future ProtocolHub products.

Advisory on finance architecture

In limited cases, we advise on aligning your internal finance stack with modern product and data principles.
