What sets Advantage apart as a superior subscription & product order management system is total flexibility. The flexibility allows you to efficiently run your business the way you want to.

Admiral is the leading adblock revenue recovery platform for publishers and the pioneer of Visitor Relationship Management (VRM). Trusted by thousands of publishers and backed by more than a decade of recovery expertise, Admiral has helped publishers recover more than $100 million in adblock revenue across trillions of protected requests. Admiral pioneered Full Spectrum Adblock Recovery to address today's fragmented adblock landscape—from browser extensions and privacy browsers to VPNs, DNS and network-level blocking, dark traffic, and more resistant blockers. Instead of relying on a single recovery technique, Full Spectrum combines four core approaches: Full-Stack Recovery, Reinsertion, Server-side Protection, and Alternative Value Exchange. Publishers can use these approaches independently or together through Combo Recovery to maximize total adblock revenue. Full-Stack Recovery restores the publisher's complete advertising stack when possible, while reinsertion—including Acceptable Ads and proxy reinsertion—adds recovery opportunities for other blocker environments. Server-side protection extends coverage to more resistant blockers, while alternative value exchanges can convert adblocked visitors through subscriptions, registrations, email acquisition, donations, and other outcomes. Admiral's VRM platform provides the intelligence and orchestration behind Full Spectrum Recovery, enabling publishers to detect and measure blocked traffic, segment audiences, target recovery experiences, sequence offers, test approaches, and continuously optimize performance. Beyond adblock recovery, Admiral helps publishers maximize revenue recovery and revenue growth through subscriptions and paywalls, consent management, first-party data, registrations, email and social audience growth, donations, journey shaping, marketing automation, and AI-powered Visitor Copilot. One audience. Multiple recovery paths. More revenue recovered.

One Platform. Total AP Control. Zahara is an accounts payable automation platform that helps finance teams keep control of spend across every site, team, project and entity, from purchase request to supplier payment, without a full ERP transformation. Control spend wherever it happens. Purchase requests are raised in seconds, from approved catalogues if you want to restrict what can be bought and from whom, then routed through multi-step approvals built around your sites, departments and projects. Approvers see the budget impact before they say yes, and approved purchase orders go straight to the supplier. Modernise without replacing your finance system. Zahara integrates directly with Xero, Sage 50 and Sage 200, QuickBooks Online and MYOB, with connectors for most other systems. Your accounts system stays the single source of truth; Zahara replaces the paper, email approvals and spreadsheets around it. Process more, with less admin. Invoices emailed into Zahara's Invoice Inbox are read by AI, which identifies the supplier, extracts line items and completes three-way matching against the purchase order and delivery receipt before routing for approval. Approved invoices flow into payment runs, including multi-currency payments with Currencies Direct. Governance built into everyday spend. Budgets are allocated to GL codes, with committed and pending spend tracked in real time. Every request, approval, invoice and payment carries a complete audit trail. Controls that scale as you grow. As you add sites, entities or acquisitions, new locations, budgets and approvers slot into the same workflows, so finance keeps visibility without adding manual checks. For staff expenses, sister product AI Expenses captures receipts automatically, routes claims for approval and reimburses your team as soon as sign-off lands. Built for service-based, growing organisations in construction, care, charities, hospitality, education and professional services, and used by finance teams at Lush, British Airways Holidays and CHD Living. Guided implementation takes weeks, not months, with UK-based support and no minimum term on monthly plans.
