Get Paid Faster. Every Single Time.
Create branded invoices, automate recurring billing, collect payments via Stripe, Authorize.Net, or PayPal — with PCI-compliant tokenized storage and automated dunning.

Why Accounting Firms Struggle to Get Paid
Most firms leave revenue on the table because billing is manual, payment options are limited, and collections require constant follow-up.
Firms wait 30 to 60 days for payment because invoicing is manual, payment methods are limited, and clients have no convenient way to pay online. Every day a receivable ages, your cash flow suffers.
Subscription billing, retainer tracking, and prepaid hour bundles are managed in spreadsheets. Monthly invoices are generated by hand, and failed payments are discovered too late to recover.
Being stuck with a single payment provider means no negotiating leverage, no backup if the processor has downtime, and no ability to offer clients their preferred payment method.

Complete Billing & Payments Platform
Eight core capabilities that handle every billing scenario your firm encounters — from one-time invoices to complex subscription models.
Create, send, and track invoices with detailed line items, percentage or flat discounts, tax calculations, partial payment support, and a running amount-paid ledger per invoice.
Firm-branded templates with your custom logo, brand colors, late fee policies, and configurable net-day payment terms. Every invoice reinforces your professional brand.
Auto-generate invoices on weekly, monthly, quarterly, or yearly schedules with background processing. Set start and end dates, and the system handles the rest without manual intervention.
Recurring billing via Authorize.Net ARB or Stripe Subscriptions with multi-line item support, automatic failure handling, and proactive notifications for expiring payment methods.
Automated multi-stage dunning with configurable retry schedules, escalation rules, and email notifications. Recover failed payments without manual intervention or awkward client calls.
Per-client credit balance with full transaction history including deposits, applications to invoices, and refunds. Apply credits to future invoices with a single click.
PCI-compliant tokenized payment storage via Authorize.Net CIM for secure one-click charging. Card data is never stored on your servers — only secure tokens are retained.
Convert logged time entries into billable invoice line items with one click. Select time entries, set rates, and generate a professional invoice without re-entering any data.
Billing Scenarios Solved
Scenario: A firm needs to invoice 300 clients for 1040 preparation within two weeks during the busiest period of the year, with minimal staff bandwidth for billing.
Batch invoice generation with branded templates and public checkout links enables 90% collection within 7 days — without a single phone call from your billing team.
Scenario: 50 bookkeeping clients on monthly retainers with different service tiers, each billed on different cycle dates, with no automated way to handle failed payments.
Automated recurring invoices with Stripe subscriptions, multi-stage dunning on failed payments, and proactive expiration alerts — zero manual follow-up required.
Scenario: A firm wants to offer clients Stripe for credit cards, PayPal for convenience, and Authorize.Net for ACH bank transfers — without managing three separate billing systems.
All three processors active simultaneously within a single billing dashboard. Clients choose their preferred method at checkout, and all transactions reconcile in one ledger.
Scenario: Advisory clients purchase 20-hour prepaid bundles that require precise usage tracking, low-balance notifications, and automatic renewal invoicing.
Automatic hour deduction per logged time entry, configurable low-balance alerts sent to both client and firm, and renewal invoicing triggered at threshold.
