We do not support partial payments.
We recommend creating multiple smaller invoices if you'd like to split up your invoice payments.
Why do we recommend this?
The reason we do this is because it can easily create a lot of confusion when it comes to reporting your income alongside your project timeline.
For example, the project timeline would only show the invoice when it was actually paid, but your income chart would show the partial payment and remaining payment as separate points on your chart.
Also, if an invoice had a partial payment on it, every time it was displayed in Bonsai, there would need to be an indication (ie "$1,000 remaining"). It can easily cause unnecessary complexity to the invoicing process.
By separating out the invoices, it makes managing the reporting and accounting far simpler for both you and your client.
