Invoicing software for small businesses, without the admin
Professional invoices in seconds
Add itemized lines, apply taxes and discounts, set payment terms and download a branded PDF with your logo and payment details. Numbering is automatic and stays in sequence even when several people invoice at once.
Send invoices where customers will see them
Email invoices straight from Frostwood, share them on WhatsApp in one click, or send an SMS payment reminder. Customers can also find every invoice in your client portal.
Always know who owes you
Track partial payments and outstanding balances per customer and issue credit notes when you need to. Receivables aging and customer statements show exactly what is overdue.
Confirmations that send themselves
When a payment is recorded, the customer automatically receives a payment confirmation with their updated statement.
Online invoicing with M-Pesa, card and bank payments
Customers can pay any unpaid invoice from your client portal with an M-Pesa STK Push prompt. The payment is matched to the invoice automatically, with its M-Pesa receipt number, and the balance updates in real time — see how the M-Pesa CRM works.
Card, bank-transfer and cash payments are recorded against the invoice in a couple of clicks, including partial payments, so every payment method ends up in the same ledger and on the same customer statement.
Invoicing software for agencies and freelancers
Agencies and freelancers bill for projects and time. Frostwood keeps invoices on the same customer record as your projects and time logs and your estimates and proposals, so you can bill for the work without re-entering anything.
International clients can be invoiced in their own currency with their own exchange rate, from the same workspace.
