Suite HUB

Modular enterprise suite for SMBs across Panama, USA, Venezuela, and Spain

product B2B ERP electronic invoicing multi-jurisdiction

The problem

Most Spanish-speaking SMBs — from Panama to Venezuela, Spain, and the US Hispanic market — run on a mix of spreadsheets, paper invoice books, and generic software that doesn’t understand their flows. When mandatory electronic invoicing kicks in (DGI in Panama, SENIAT in Venezuela, Facturae/VeriFactu in Spain, state-level compliance in the US), friction multiplies: they have to integrate a PAC, maintain the tax catalog, handle offline contingency, and emit valid documents. Market alternatives are either too expensive (international ERPs) or too basic (invoice templates), and rarely adapt to the specific sector of the business.

My role

As founder, lead architect, and product lead of Suite HUB — a PROOQ LLC (USA) product with local operations in Panama through PROOQ S.A. — I drive product strategy, technical decisions, and day-to-day implementation of the monorepo, alongside the relationships with the first clients in production.

The solution: two orthogonal axes

The strategy that sets Suite HUB apart is splitting the platform into two dimensions that combine freely:

Editions — the horizontal axis

Levels of the base platform. Same modular core, different limits and available modules. They apply to any sector.

  • HUB Lite — SQLite without Composer, for small businesses (1 location, ≤3 users).
  • HUB Core — SQLite + Composer + DGI electronic invoicing, for the standard SMB.
  • HUB Pro — MySQL + HTMX, multi-location, API, automations, white-label.
  • HUB Enterprise — upcoming, multi-tenant for chains / franchises.

Verticals — the vertical axis

Specialized packages by sector. They sit on top of an edition. Today: HUB Taller (auto shops), Restaurant, POS, Pet, Beauty, Clinic, Gym, Hotel, Inmobiliaria (real estate), Lavandería (laundromats), Phone (repair), and Traffic. Each vertical brings its own modules, flows, and templates.

A real client looks like “HUB Taller on Edition Pro with Digifact PAC”. That combinatorial freedom lets us cover wildly different verticals without maintaining N separate products — one core, many contexts.

Technical architecture

  • Monorepo with a static marketing site (Astro 5 + Tailwind) and PHP 8.2 strict client applications.
  • Single-tenant per installation: one database per client, multi-location lives inside the tenant. This avoids the operational and security complexity of shared multi-tenancy for our segment.
  • Module auto-discovery via modules/{key}/module.json. Installing a module means copying a folder. If a dependency is missing, the module is automatically hidden.
  • Central licensing portal (portal.prooq.com) with /api/validate.php endpoint that all client installations consume. A single source of truth for commercial state.
  • Frontend stack consistent across apps: Tailwind 3 + Flowbite + Alpine.js 3 (with HTMX 2 added in HUB Pro for richer server-driven interactions).

Multi-jurisdiction electronic invoicing

Suite HUB does not invoice on its own — the client contracts their local PAC and we integrate. The PAC adapter layer is designed to abstract differences across jurisdictions behind a single interface.

Panama — DGI (live in production): we support three PACs:

  • Digifact (default)
  • The Factory HKA
  • Factura Fácil

The adapter layer was rewritten in HUB Core (gen 2) with PHPUnit tests verifying 32 specific DGI rules. Gen 1 is still in legal production serving thousands of real electronic invoices — the transition is done with surgical care.

2026 roadmap — three more jurisdictions:

  • Venezuela — SENIAT: integration with certified digital printers and emission compliant with the current Administrative Providence.
  • Spain — Facturae / VeriFactu: compliance with the Crea y Crece Law (mandatory B2B) and Facturae format for B2G.
  • USA — state-level compliance: standard invoicing + state-by-state sales tax (Avalara / TaxJar evaluated as integrations), focused on Hispanic SMBs.

Live in real production (Panama) + soft launch (USA, Venezuela, Spain)

Today Suite HUB runs with real Panamanian clients, in verticals as diverse as a car repair shop in La Chorrera (HUB Taller + Pro + Digifact) and a specialty sneaker laundromat in Panama City (HUB Lavandería + Core + HKA). Both cases are documented with real KPIs at suitehub.net/cases.

For USA, Venezuela, and Spain we are in soft launch / evaluation: the multi-jurisdiction architecture is already designed, the first leads are in conversation, and full commercial launch is planned for 2026 as each country’s tax adapter is closed.

Closed decisions that shaped the product

  1. PHP 8.2+ strict as the technical floor. A deliberate decision to keep hosting cheap (XAMPP / cPanel / Hostinger) without sacrificing typing.
  2. WhatsApp-first as the sales and support channel. All four target markets (Panama, US Hispanic, Venezuela, Spain) are WhatsApp-native; fighting that was a losing battle.
  3. Single-tenant by DB to avoid the isolation complexity that shared multi-tenancy brings with a small team.
  4. PWA with manifest.json + sw.js in client apps so that waiters, mechanics, and operators can install the system as a mobile app without going through stores.

What’s next

  • Full commercial launch in USA, Venezuela, and Spain during 2026, once each jurisdiction’s tax adapter is closed.
  • HUB Enterprise multi-tenant for chains and franchises (under evaluation).
  • More verticals opening as early clients ask for specific functions.
  • Internal module marketplace so partners can contribute.
