One bill does not always get settled in one go. Break the total into segments with their own due dates, or set a floor and let the client decide what to send above it. Either way the invoice keeps its own running balance.
What is inside
Split payments are your schedule: you decide the segments and the dates. Partial payments are the client's: you set the minimum and they choose the rest. Both run on the same invoice.
You set the schedule
Decide how a large invoice comes in: a third on signing, a third at the halfway point, the rest on delivery, or any breakdown that matches the work. It suits phased deliverables and longer contracts where asking for the full sum up front would stall the job.
Every split carries its own date, so the client knows what is owed and when rather than facing a single deadline. It also makes the year predictable at your end: the schedule you agreed is the schedule the invoice enforces, and each date is chased on its own.
The client sets the amount
A partial payment starts with a floor. Set the smallest amount you are willing to take against the invoice, whether that is a flat deposit or enough to cover materials, and the client cannot pay less than that at the first attempt.
Above the minimum, the amount is theirs to pick. A client with a good month can clear most of the bill; a client with a tight one can pay what they have and come back to the rest. Anything extra reduces the outstanding balance straight away.
The invoice does the bookkeeping
Each payment is written against the invoice as it arrives, with the date it was received and the amount. The outstanding total drops to match, so what a client owes is never a matter of adding up receipts from three different weeks.
A split payment schedule is only useful if someone remembers it. Reminders go out ahead of each due date, so the client is warned before the amount is late rather than after, and you are not the one sending the same email four times.
Also included
Flexible payment terms only work if the record keeping keeps up. These are the parts that make sure it does.
Reminders are sent ahead of each split due date without you scheduling them by hand.
The document reflects every payment as it is made, so records stay current.
Track the status of each split and partial payment from one screen.
Part payments run through the same processors and security as a full payment.
A client can settle one split with PayPal and the next with a card.
Part-paid invoices show what is still owed in the aged debt report.
Clients see what they have paid, what is left and when the next amount is due.
An approved estimate can become an invoice that is then split into stages.
Staged payments and repeating invoices can both run in the same account.
Each amount received posts to the ledger on the date it actually arrived.
A staged invoice in a client's currency is paid in that currency each time.
For a fixed-price product, a payment link takes the whole amount up front instead.
Questions
Yes. The two are settings on the invoice rather than a permanent choice about the client, so a job that started with a fixed schedule can move to a minimum-plus-flexible arrangement if the circumstances change part way through.
Each split has its own due date, and a reminder goes to the client a few days ahead of it. That means one invoice can generate several reminders over its life, each one about the segment that is coming up rather than the whole balance.
The full amount is recorded and the outstanding balance falls by however much came in. There is no rounding to the nearest installment and no credit sitting in limbo: the invoice simply shows a smaller figure still to pay.
No fixed limit. Break an invoice into as many segments as the contract calls for, whether that is two payments across a month or a dozen across a year of retained work. Each one carries its own amount and its own date.
That is what the minimum amount is for. Set it to the deposit you need, send the invoice, and the client cannot pay less than that figure to begin with. The balance then sits on the same invoice until it is cleared.
They go through the same connected gateways, with the transaction handled on the processor's side. Nothing about paying in stages changes how the money is taken; it changes only how much is taken and when it is taken.
Stage a large bill across the months it takes to deliver, or set a floor and let the client fill in the rest. The balance keeps itself straight either way.
