Rev.io PSA supports a wide range of billing models to accommodate the diverse ways MSPs and service providers charge their clients. This includes hourly billing (time and materials), flat-rate recurring monthly fees (managed services), project-based fixed-fee billing, hybrid models that combine recurring and usage-based charges, and ad hoc billing for one-time services or equipment. For communications providers, Rev.io also supports usage-based billing for voice, data, and other metered services. This flexibility ensures that your billing engine matches your actual service delivery model without workarounds.

Rev.io connects time tracking, service tickets, projects, and inventory directly to the billing engine, creating an automated time-to-invoice pipeline. When a technician logs time against a ticket or uses materials on a job, that data is automatically queued for billing based on the client's contract terms and rate structure. This tight integration eliminates the revenue leakage that commonly occurs when billing relies on manual data entry or disconnected spreadsheets.

Yes. Rev.io's billing engine is built to handle the invoicing complexity that service providers face. A single invoice can include recurring managed service fees, hourly labor charges, project milestone payments, equipment and materials, and applicable taxes and surcharges. Rev.io also includes a built-in tax calculator that automatically applies the correct rates based on service type and jurisdiction, which is especially important for telecom and communications providers subject to complex regulatory tax requirements.

Rev.io integrates with QuickBooks Online to sync invoice data, payments, and customer records between your PSA and accounting system. When an invoice is generated in Rev.io, the relevant financial data can be pushed to QuickBooks automatically, eliminating double entry and ensuring that your books stay in sync. Payment records also flow back, so your PSA reflects accurate account balances at all times. This integration lets your operations team manage billing within the PSA while your finance team works in the accounting system they're already comfortable with.

Rev.io's billing stands apart because it was born from 20+ years of experience in telecom and communications billing - one of the most complex billing environments in any industry. While most PSA platforms offer basic invoicing for managed services, Rev.io natively supports usage-based rating, telecom tax compliance, multi-carrier settlements, and hybrid billing models that combine recurring, usage, and project-based charges. This heritage means Rev.io can handle billing scenarios that other PSA platforms simply cannot, making it the ideal choice for MSPs and service providers who offer both IT services and communications or connectivity products.
