Crypto payment systems

Accept, settle, reconcile and account for digital asset payments.

Engagement
Fixed-scope build, live on one product line first
Typical timeline
5 weeks
Starts with
A decision on which assets and networks you will accept, and what you will settle into.
01The situation

A customer pays in a stablecoin, sends it four minutes after the quote expired, and arrives three dollars short because the network fee came out of the amount. Your accountant needs one figure in dirhams, your customer wants the order released, and somebody is matching all of this by hand in a spreadsheet.

Why it matters

New payment rails with clean books behind them.

On-chain products, audited by default.

What we build

Concrete artefacts, handed over and documented.

01

A payment request with a quoted rate, a visible expiry and an agreed tolerance, so small shortfalls resolve by rule instead of by argument

02

A unique deposit address or reference per invoice, which is what makes automatic matching possible at all

03

Handling for underpayment, overpayment and late arrival, with the customer told what happened without needing to contact anyone

04

Automatic conversion into your settlement currency on receipt, if you would rather not carry the price movement

05

A ledger export that reconciles to your accounting system, recording the fiat value at the moment each payment landed

What changes

01

Digital-asset payments settle and reconcile without manual matching

02

Exposure between quote and confirmation becomes a policy rather than an accident

03

Finance closes the month with crypto revenue sitting in the same ledger as everything else

How it runs

Week 1

01Assets and policy

Which assets and networks you accept, what you settle into, and how much of a shortfall you are willing to absorb.

02Payment flow and matching

Quoting, addresses, confirmation tracking and the automatic matching of payments to invoices.

Weeks 4–5

03Accounting and go-live

Refunds, the ledger export, a reconciliation your finance team signs off, then live on one product line.
