Monk submits into more than 600 of them, including Coupa, Ariba and SAP Business Network, and uploads 87% autonomously. Julia, the Monk agent for Intelligent Collections, reads customer replies and responds to what was written rather than advancing a fixed dunning sequence. 90% of invoices resolve without escalation. Email sends from your own mailbox via Gmail or Microsoft 365, so there is no new sending domain. Payments match to open invoices at 80%, rising to 95% with rules your team configures.

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.
