Modern B2B SaaS companies face a fundamental tension: pricing models grow more complex while finance teams struggle to keep pace. Usage-based pricing has become an established model in SaaS. Growth Unhinged's 2026 survey of more than 230 B2B software and AI companies found that 37% use hybrid pricing models combining subscriptions and usage, up from 25% a year earlier.
The gap between what billing software promises and what finance teams actually need has become a strategic problem. Tabs positions itself as an AI-native revenue automation platform focused on revenue workflows, making its pricing structure relevant to billing infrastructure decisions. For companies evaluating their options, a robust usage-based billing engine should handle not just invoicing but the full revenue lifecycle from metering to recognition.
Key takeaways
- Tabs offers four pricing tiers: Launch at $2,000/month (up to $5M annual revenue and 100 contracts), while Growth, Scale, and Enterprise are custom-priced
- AI capabilities including contract ingestion, automated collections, and billing agents are included at all pricing tiers without additional fees
- Tabs reports that more than 30% of its customers adopted usage-based pricing in under 30 days. Full implementation timelines vary with contract complexity, data migration, integration requirements, and selected services
- Simple usage billing is available at any tier, but complex usage billing requires Scale tier or higher. QuickBooks Online integration is available at Launch, while simple NetSuite or Sage Intacct implementations may qualify for Growth pricing following review

Understanding core billing software for small businesses
What billing software does for growing companies
Billing software automates the workflows connecting customer usage to cash collection, including metering, price calculation, invoicing, payment collection, and revenue recognition. For businesses moving beyond flat-rate subscriptions, usage-based, tiered, and hybrid pricing can make manual processes harder to maintain.
In a Deloitte case study, a wealth management firm experienced revenue leakage of 3-4% due to mismatches between contracts and invoices.
Key features for efficient operations
Billing automation typically covers invoice scheduling, payment retries, usage alerts, ERP synchronization, and audit trails. Tabs uses a contract-first architecture in which signed agreements inform billing logic. Its AI extracts terms from PDF contracts to generate billing schedules, collections workflows, and revenue recognition entries.
Transitioning from manual processes
Companies often move from spreadsheets when invoice volumes, customer-specific calculations, compliance requirements, or collection delays strain manual workflows.
Tabs reports that more than 30% of its customers adopted usage-based pricing in under 30 days. Full implementation timelines vary with contract complexity, data migration, integrations, and selected services.
Selecting the best billing and invoicing software
Evaluating features for growth
The best billing software anticipates how your pricing model will evolve, not just how it operates today. Companies that select platforms based solely on current needs often find themselves migrating again as complexity increases.
Key evaluation criteria include:
- Pricing model flexibility: Can the platform handle your current model and plausible future variations? This includes usage-based pricing, tiered pricing, volume discounts, prepaid credits, and hybrid combinations.
- Integration depth: Does the platform connect natively to your ERP, CRM, and payment processors? Tabs integrates with QuickBooks Online at all tiers. Simple, uncustomized NetSuite or Sage Intacct implementations may qualify for Growth pricing following review, while more complex integration requirements can affect the applicable plan and pricing. This tiered integration access shapes the total cost for companies already using enterprise ERPs.
- Metering capabilities: How does the platform ingest and process usage data? Some platforms require pre-aggregated data, while others like Orb persist raw usage events that enable retroactive calculations and historical corrections.
- Scalability architecture: Can the platform handle your projected transaction volume without performance degradation or architectural limits?
Understanding Tabs' pricing tiers
Tabs structures pricing across four tiers designed to scale with company growth:
- Launch ($2,000/month): Designed for companies up to $5M in annual revenue with up to 100 active contracts. Includes contract processing, automated billing, collections, reporting, and ASC 606 revenue recognition. Simple usage billing (price times quantity) is available. QuickBooks Online integration included.
- Growth (Custom pricing): Serves companies from $5M to $20M annual revenue with up to 500 contracts. Simple, uncustomized NetSuite or Sage Intacct implementations may qualify for Growth pricing following review. Multi-entity support and international capabilities available as add-ons.
- Scale (Custom pricing): Handles companies from $20M to $50M annual revenue with up to 2,000 contracts. Unlocks complex usage billing scenarios beyond simple price-times-quantity calculations.
- Enterprise (Custom pricing): Supports companies above $50M annual revenue with unlimited contracts. Includes custom workflows and dedicated support.
A notable aspect of this structure: AI capabilities are included at every tier. The Contract Agent, Collections Agent, Billing Agent, and Revenue Agent features come standard without additional fees.
Streamlining accounts receivable automation with advanced software
Automating collections and follow-ups
Accounts receivable automation covers dunning sequences, failed-payment retries, cash application, and aging reports. Effective finance workflows give finance teams visibility into receivables while reducing manual collection work.
Tabs' Collections Agent generates dunning emails using account context, including payment history, contract terms, and customer relationships. Tabs reports the following customer outcomes:
- Statsig: An 80% reduction in aged receivables while scaling billing volume 3x without adding finance headcount.
- Cortex: A 50% reduction in overdue invoices, with effort per invoice falling from 5-10 minutes to seconds.
These are customer-specific outcomes, not guaranteed performance metrics.
Integrating with existing finance systems
Relevant integration categories include ERP systems, payment processing, CRM synchronization, and cash application. Tabs offers QuickBooks Online integration at all tiers. Simple, uncustomized NetSuite or Sage Intacct implementations may qualify for Growth pricing following review, while more complex integrations can affect the applicable plan and pricing.
Revenue recognition and financial compliance
Automating recognition for compliance
Revenue recognition under ASC 606 (US GAAP) and IFRS 15 (international standards) requires a five-step model that becomes operationally complex for usage-based and hybrid pricing:
- Identify the contract with a customer
- Identify performance obligations in the contract
- Determine the transaction price
- Allocate the price to performance obligations
- Recognize revenue as obligations are satisfied
For subscription businesses, these steps can be straightforward when contracts include clear performance obligations. But usage-based pricing introduces variable consideration that requires careful treatment.
Revenue recognition software automates this complexity by:
- Mapping consumption to performance obligations in real time
- Generating journal entries with proper accounting treatment
- Supporting audit trails that link recognized revenue to underlying events
- Handling deferred revenue calculations for prepaid arrangements
- Managing unbilled revenue for usage accrued but not yet invoiced
Tabs includes ASC 606 compliance at all pricing tiers, with advanced complex usage scenarios requiring Scale tier. Every automated action logs with full traceability for audit readiness.
Ensuring accuracy and compliance in billing operations
The importance of audit readiness
Financial audits, M&A due diligence, and compliance reviews depend on traceable billing records. A documented audit trail helps establish how a charge or accounting change was produced. Relevant controls include:
- Event lineage: Linking invoice charges to the underlying usage events.
- Change history and access controls: Recording modifications, authorizations, and adjustments.
- Period locks: Protecting closed accounting periods from retroactive changes.
Retaining raw usage events provides detailed records for investigating charges and supporting billing corrections.
Data integrity in complex billing models
Complex billing models create opportunities for errors in dimensional pricing, tier thresholds, proration, currency conversion, and prepaid credit application. Small discrepancies can accumulate across customer accounts.
Orb retains raw usage events to support eligible backfills and backdated pricing changes, recalculation of affected draft invoices, and governed correction workflows for finalized invoices. Tabs combines contract-based billing automation with event-level usage tracking and auditing.
Why Orb delivers revenue infrastructure for usage-based pricing
While Tabs approaches billing through a contract-first AI architecture, Orb takes a fundamentally different approach designed for usage-based and hybrid pricing complexity.
- Raw usage event architecture: Orb preserves raw usage events for historical calculations, eligible backdated adjustments, and audit trails that connect charges to their source events. When enterprises need billing corrections, contract amendments, or retroactive promotional credits, Orb supports governed correction workflows.
- SQL-based metrics: Orb lets teams define billing metrics using SQL queries, enabling complex aggregations like averages, maximums, minimums, and custom calculations. This flexibility supports sophisticated usage calculations beyond simple price-times-quantity scenarios.
- Dimensional price groups: Orb's dimensional price groups support pricing across multiple usage dimensions, such as region, instance type, and environment, using a single pricing configuration for dimension combinations. A cloud infrastructure provider can apply different rates across combinations without maintaining separate pricing logic for each permutation.
- Pricing simulations: Orb's pricing simulations test proposed pricing models against historical customer usage, showing projected revenue and customer-level impacts without affecting production billing.
- Proven scale: Supabase processes more than 1.5 million invoices monthly through Orb. Vercel reported an 80% reduction in the time required to build and launch billing for new products, while Stytch reduced time spent processing bills and invoicing by 75%. Replit experienced 40x revenue growth since using Orb to monetize usage. These are individual customer outcomes reflecting their specific implementations.
- Enterprise compliance: Orb maintains SOC 1 and SOC 2 Type II reports and offers audit logging with accounting period locks that prevent retroactive changes to closed periods. Enterprise plans include a 99.9% SLA, with a 99.99% commitment available through a paid support add-on.
- Native NetSuite integration: Orb's NetSuite integration creates native transaction records, including invoices, credit memos, and customer deposits, supporting reconciliation and financial reporting within existing ERP workflows.
For companies evaluating billing infrastructure, the question is whether your operational needs align better with contract-centric AI automation or with an architecture designed for usage-based pricing flexibility and event-level accuracy. Orb's approach treats pricing as a strategic function integrated across product, finance, and go-to-market teams, enabling revenue design rather than just billing execution.
Frequently asked questions
How does Tabs handle complex enterprise contracts with non-standard terms?
Tabs uses AI to ingest signed contracts in PDF, Word, or email formats and extract billing terms, pricing structures, billing schedules, and recognition terms. It interprets terms in their commercial context and converts elements such as ramp schedules, usage thresholds, and custom clauses into billing workflows. Tabs does not include CPQ (Configure-Price-Quote) functionality for pre-signature quote creation, which is handled through separate tools or CRM-native quoting.
What happens when a company outgrows the Launch tier contract limits?
The Launch tier supports up to 100 active contracts. Growth supports up to 500 contracts with custom pricing, potential eligibility for NetSuite or Sage Intacct integration, and multi-entity support as an add-on. A tier transition may involve revised contract terms and implementation of newly available features.
Does Tabs support prepaid credit models common in AI and API businesses?
Tabs supports prepaid commitments and credit-based usage arrangements, including drawdowns, overage charges, and contract-specific payment schedules. The platform handles simple usage billing at all tiers, while complex usage scenarios require Scale tier or higher. Orb also supports prepaid credits, including platform-wide and SKU-scoped credit pools, configurable expiration, and automated drawdown tracking.
Can Tabs handle the billing requirements of companies with both self-serve and enterprise sales motions?
Tabs supports both product-led growth and sales-led motions, with self-serve card charges and enterprise invoicing plus ACH collection. Launch supports up to 100 contracts, which may be reached before the $5M revenue threshold by companies with high-volume self-serve signups. Enterprise supports unlimited contracts with custom pricing.
What are the key differences between Tabs' contract-first approach and raw usage event architectures?
Contract-first architecture treats signed contracts as the source of truth and uses AI to extract billing logic from agreement documents. Tabs combines this contract-based automation with event-level usage tracking. Raw usage event architectures retain event-level data for billing calculations, historical corrections, and complex aggregations. The distinction is whether the central workflow emphasizes interpreting contract terms or calculating charges from usage data.
