Zoho Invoice lets you invoice customers by email, track receivables, and collect payments online.

All businesses need to invoice their customers for products and services supplied. Invoicing is, of course, available in accounting packages that also track accounts receivable and handle many other chores such as financial statement preparation.

But if you don't want the hassle of installing full-fledged accounting software and keeping your records up to date, you can use an online service that handles just the billing and collection services you require.

That's the appeal of Zoho Invoice, part of a growing suite of online business services from Zoho. Zoho Invoice lets you invoice customers by email, track receivables, and collect payments online.

The flexibility of Zoho's suite design means you can share common data with other, extra-cost Zoho services, such as Zoho CRM (customer relationship management) and Zoho Projects. You may also export data to accounting apps in CSV, Excel, and other formats. But if invoicing is all you need, you can use and pay for just that.

The free edition of Zoho Invoice limits you to five invoices per month. Yet even the high-end plan, which offers sufficient capacity for most small businesses, costs a relatively modest $35 per month.

Despite its low cost, Zoho Invoice offers enough flexibility in invoice forms and sales reporting to suit the billing needs of almost any small business. If you don't require a complete integrated accounting program, but want to automate your sales invoicing and collections, Zoho Invoice could offer just the right mix of services for you.
