JustPaid

For venture-backed SaaS companies burning cash and scaling ARR fast, JustPaid offers a rare combination of near-zero implementation drag, quantifiable ROI, and AI differentiation that legacy vendors have failed to deliver.

Automated Invoice Generation

Once a sales contract is uploaded or a closed-won opportunity is synced from Salesforce, JustPaid auto-creates either usage-based or fixed-fee invoices. For usage models, the platform can ingest event streams via Segment or RudderStack and bill against predefined pricing matrices (e.g., $0.08 per 1 000 API calls with volume discounts). Invoices are branded, multi-currency, and compliant with local tax rules thanks to an integration with Avalara.

Smart Collections

Instead of generic dunning e-mails, JustPaid’s LLM composes hyper-personalized messages that reference the customer’s onboarding date, last NPS score, and payment history. A/B tests conducted with 47 000 invoices showed a 27 % increase in on-time payments when AI-generated messages were used versus static templates.

Subscription & Plan Management

Unlike Stripe Billing, which locks customers into Stripe’s payment rails, JustPaid sits on top of multiple gateways (Stripe, Adyen, Braintree) and allows mid-cycle plan changes across all subscribers in one click. Prorations and revenue-recognition adjustments are calculated automatically.
