Q&A

  • What is a ledger?
  • A ledger is the system of record of all your transactions and balances, i.e. the central repository in which double-entry accounting transactions are stored and summarized. It lays the groundwork for reconciliation, which is the process of ensuring every transaction in your payment system has actually occurred and is recorded accurately, depending on its specificities (e.g. a refund is handled and recorded differently than a transaction with a discounted price).

  • Why do I need a ledger?
  • 1/ Real-time payment data and financial information are consolidated in one place, allowing greater visibility across all the underlying platforms involved in online transactions; 2/ From financial data perspective, pay-ins and payouts are reconciled automatically and painlessly. You won’t miss any discrepancies between pay-ins and payouts, even in the most complex payment schemes; 3/ From a compliance perspective, a ledger is a key component to meet your regulatory constraints as it is the basis for audit reports and financial statements. ------------------------------------------------------------------------ « Reconciliation is one of the trickier aspects of a business, regardless of whether it’s a sole trader, SMB or a larger organization, as it involves balancing money going in and out simultaneously across multiple parties, and the various fees that are potentially paid as that money moves around. The bigger an operation (regardless of organization size), the more complex it becomes. The smaller the organization, the more critical the work is since it’s closely linked to cashflow » - TechCrunch

  • I already use Stripe, can I use Numary?
  • In short, yes. Numary is not a payment processor, it rather helps you tie them together. As soon as you start to have tables to track money in your system, e.g. between pay-ins and payouts if you're a marketplace, using the Numary ledger can make your life much easier.

  • I want to add my own points system to my app, can I use Numary?
  • Numary lets you move assets between virtual ledger accounts through transactions. These assets can be anything from EUR to MADE_UP_POINT, which is great foundation for home-grown in-app points and credits systems.
