Invoicing
Quotes and invoices that get you paid
Send a quote, turn it into an invoice in one click, and follow every invoice until it's paid. Each invoice posts to your books automatically, so your receivables and VAT are always up to date.
Free to start. No credit card needed.

From quote to invoice in one click
Write a quote with your products and prices, send it, and turn it into a sales order, a deposit invoice or the final invoice when the customer says yes.
- Customers can accept or decline a quote online and leave a note
- Prices follow each customer's price list and quantity breaks
- Line discounts, tax per line and amounts with or without VAT
Invoices that look like your business
Choose a layout, add your logo, colours and payment details, and give a customer their own template. Every invoice is a PDF and a private link your customer can open on their phone.
- Email invoices from CoreBooks, to several addresses with copies
- See when the customer opened the invoice
- Both tax numbers, VAT per rate and the supply date on the invoice
Get paid without chasing
Turn on payment reminders and CoreBooks emails customers before and after the due date, in polite then firmer words, in English or Dutch. Late fees are proposed for you to charge, never added on their own.
- Recurring invoices for retainers and subscriptions
- Monthly statements for every customer with a balance
- A private customer portal with all their invoices and quotes
Credit notes, deposits and withholding tax
Correct an invoice with a credit note, ask for a deposit up front with its VAT, and take it off the final invoice. When a customer withholds tax, the invoice shows it and the balance due stays right.
Available on
Every plan. Free includes 25 invoices, quotes and bills a month. Recurring invoices, reminders, late fees, online quote acceptance, deposits and the customer portal are on Pro and Business.
Questions and answers
Can I invoice in US dollars and Surinamese dollars?
Yes. Each invoice has its own currency and exchange rate. Your reports convert everything to your base currency, and exchange differences on payments are booked automatically.
Can my customer accept a quote online?
Yes, on Pro and Business. The customer opens the quote's link, accepts or declines it with their name and a note, and you get an email. CoreBooks can make the draft invoice for you.
Do the invoices meet the Surinamese VAT requirements?
CoreBooks prints what article 28 of the Wet BTW asks for: a sequential number, both tax numbers, the VAT per rate with the amount it's on, exemptions, the supply date and "BTW verlegd" when the buyer accounts for the VAT.
