An integration usually starts with one job: getting money in, or getting it out. These are the four shapes that job takes. Find yours, read the row, and start where it points — the rest is there when you need it.

Collect deposits

You need money to arrive from your customers, and you need to know whose it is. Each of your customers gets their own account details. When a payer sends money there, it is credited to that customer and to nobody else, and Kira tells you the moment it lands. You never have to reconcile a shared account or match a payment to a person by its reference. Typical of marketplaces crediting a seller, platforms collecting subscriptions, and anyone invoicing customers who pay by bank transfer.
  • What you need first: your customers verified, and an account opened for each.
  • What you can skip for now: recipients and payouts entirely.
  • Start with: How money moves, steps one to three.

Pay out to suppliers

You need money to leave, to people or companies you already know. You save each supplier or contractor once, with their bank account or wallet, and pay them repeatedly without re-entering anything. Kira reports each payment through to delivery, and tells you why if one fails. Typical of paying contractors abroad, settling with suppliers, and paying sellers what they are owed.
  • What you need first: money already available — either arriving from outside, or a balance you hold.
  • Choose how to send: the rail decides how fast it lands, and the rails differ. Choose deliberately rather than by default — see Rail.
  • Start with: How money moves, steps four and five.

Hold and draw down a balance

Money arrives once and leaves in pieces, over time. A balance can sit indefinitely at no cost, and you pay out of it whenever you choose. Because the money was already charged when it arrived, drawing it down is cheaper than moving new money in for each payment. Typical of funding a payroll run, topping up once and paying many suppliers, and any business that would rather move money in bulk than per transaction.
  • What you need first: an account with money in it.
  • Why it is worth doing: one arrival charge instead of many — see How you’re charged.
  • Start with: How money moves, step four.

Convert

Money arrives as one kind and has to leave as another. Cash to digital currency, digital currency to cash, or one currency to another. Kira performs the conversion as part of the movement, and shows you both the rate applied and the market rate it came from. Typical of paying an overseas contractor in their own currency, accepting digital currency and settling in cash, and holding value in one form while paying in another.
  • What you need first: the same as a payout, plus knowing which form the money has to arrive in.
  • What you pay: money is charged on the way in and again for the conversion — the two are separate charges, and the rate is only firm while a quoted price is locked.
  • Start with: How you’re charged, the conversion section.

Still not sure

Nearly every integration is collect and pay out, with holding and conversion added when the business needs them. If that sounds like you, read How money moves straight through — it is the whole path, and you will recognise which parts are yours. When you are ready for the technical detail, the Quickstart goes from credentials to a first payment, and Test the full lifecycle in the sandbox does the same end to end against test money.
