Best Billing and Invoicing Software: 7 Platforms for Subscriptions, Services and Small Business

Billing and invoicing software looks interchangeable until the business changes shape. A freelancer needs a fast invoice and a payment link. A SaaS company needs plan changes, proration, usage charges and dunning. A consultancy needs time entries turned into invoices. The right tool depends on which of those jobs you do most often.

Two compliance points apply to almost every buyer. Records must be kept for tax purposes, and the IRS guidance on how long to keep records explains retention periods for US businesses. If you accept cards, the PCI Security Standards Council sets the rules for handling cardholder data, which is why most teams use a hosted payment page rather than storing card details.

A well-known example of billing infrastructure is Stripe Billing. The seven platforms below span subscription engines, small business invoicing and professional services billing, and each connects to accounting, CRM and ERP systems in a scaling B2B SaaS stack. For deeper subscription coverage, see our guide to subscription billing software for SaaS.

What Billing and Invoicing Software Does

Billing and invoicing software generates invoices from orders, subscriptions or time entries, sends them, collects payment and records the result for accounting. Advanced platforms add recurring schedules, tax calculation, dunning for failed payments and revenue reporting.

• Invoice creation: templates, line items, discounts, taxes and multi-currency support.
• Payments: cards, bank transfers and wallets, with reminders and receipts.
• Recurring billing: plans, trials, proration, upgrades and usage charges.
• Reporting: aging, collections and links to the general ledger.

Measuring Collections: Days Sales Outstanding

Days sales outstanding, or DSO, measures how long it takes to collect payment after a sale. A falling DSO after adopting new billing software signals that reminders, payment links and cleaner invoices are working.

Accounts receivable is the unpaid invoice balance at period end, total credit sales is revenue invoiced on credit during the period, and the number of days is the period length, such as 30 or 90. Track it monthly.

How to Choose Billing and Invoicing Software

Choose by billing model first, then integration, then cost. A subscription business should shortlist engines built for recurring charges, while a service business should favor time-to-invoice workflows and a very small business can start with a free tool.

• Define billing types: one-off, recurring, usage-based or milestone.
• Check tax handling for the regions you sell into.
• Confirm accounting and CRM integrations before buying.
• Test failed payment and refund workflows.
• Estimate total cost, including payment processing fees.
