One platform for the whole commerce chain

Commerce infrastructure, not a merchant account.

Most providers sell you an account and lock the stack to it. High Wire runs underwriting, checkout, routing, fraud, disputes, payouts, and a reconciled ledger across every processor you use, including the MIDs you already hold.

Platform

One platform, from underwriting to reconciliation.

Onboard the merchant, accept the payment, screen it for fraud, route it for approval and cost, handle the disputes, pay out, and reconcile every dollar against the bank. Every stage runs on one merchant record and one API, and shows up in the same portal.

Get approved and boarded.

Apply once. We verify the business and everyone behind it, then board it onto PSPs that fit, or connect the MIDs it already has.

Ledgering and reconciliation

One ledger. Every dollar accounted for.

Transactions, settlements, fees, refunds, reserves, disputes, and bank deposits all land in one ledger and are matched automatically. Every figure on a statement traces back to the event that caused it.

Matched

99.94%

4,231 batches, 12 exceptions open, day closed at 06:14 UTC

Sample figures. A day is not closed until all three agree.

Settlements reconcile on their own

Every processor settlement file is parsed and matched line by line against the ledger. Nobody opens a spreadsheet to close a day.

The whole lifecycle, not just the sale

Authorizations, captures, refunds, fees, reserves, disputes, and payouts all recorded against one payment ID, with the fee breakdown attached.

Deposits matched to what you were owed

Bank credits are tied back to the settlements that produced them, so you know a deposit is right before you spend against it.

Missing money becomes a worked item

Short-funded batches, fee variances, duplicate refunds, and returned payouts surface as exceptions with an owner and an age, instead of quietly shrinking a payout.

One history across every processor

Multiple MIDs and processors settle on different schedules in different formats. The ledger normalizes them into one financial record that survives a switch.

Close the month once

A close checklist per entity and per processor, with journal entries exported to your accounting system as CSV or through the API.

Every transaction accounted for. Every settlement reconciled.

Built for

Your business, your portfolio, your platform, or your bank.

Merchants take payments directly. Agents and ISOs board and manage portfolios. Platforms embed payments in their own products. Banks and processors take merchants we have already underwritten.

Portals

A portal for everyone on the platform.

Merchants, agents, and platforms each get a workspace built for their job, running on the same live data.

Agentic commerce Preview

Specialist AI agents on every onboarding, payment, and dispute.

Two engines of collaborating agents make decisions in real time, explain each one, and learn from outcomes. An oversight agent tunes thresholds within guardrails, and your team stays in control of anything significant.

    Every routing decision records its reasoning and confidence, so operators can review or override it.

    Underwriting

    The platform is what gets complex merchants approved.

    Partners see a portfolio that is already screened, reserved, and reconciled, not a form filled in once at signup. Appetite differs by partner, so a file goes to the acquirer it actually fits.

    The platform de-risks the transaction

    Fraud screening, dispute handling, reserves, and reconciliation run on every transaction we board. Risk is measured continuously instead of guessed once at signup, and the partner can see it.

    The relationships place the merchant

    Appetite differs by partner and by category. A file goes to the acquirer whose appetite fits it, underwritten up front in the format they accept, instead of the one that happened to receive it.

    Categories are samples. See what underwriting looks for.

    Questions we get in the first call.

    The short answers are here. The ones that turn on your category, your volume, or the processor you already use come from a person on the first call.

    Why not go to a processor directly?

    You can, and some merchants should. High Wire is worth it when approval is uncertain, when one processor is a single point of failure, or when you need one set of books across several of them. We do the underwriting once and submit it to partners whose appetite matches your business.

    What happens if a processor declines me?

    Your file goes to another partner without starting over. Nothing about your integration changes, because you built against High Wire rather than against a processor.

    Can I keep the merchant account I already have?

    Yes. Connect existing MIDs alongside any we board for you. Checkout, screening, disputes, reconciliation, and payouts work the same across all of them, and routing rules decide which one takes each payment.

    How long does boarding take?

    It depends on the category and how complete the application is. We publish a median time from application to live MID, and your agent or account contact can tell you what to expect for your profile.

    How do reserves work?

    Where a partner requires a reserve, the amount, type, and release schedule are visible in the portal and in the ledger from day one, not discovered at payout time.

    Do you work with high-risk categories?

    We underwrite businesses that many processors decline, which is why the underwriting work happens before anyone is asked. Some categories remain out of scope, and we will tell you that early rather than after you have integrated.

    Do we have to use the whole platform?

    No. The products are modular, and the set that applies can differ from one transaction to the next, because the acquiring rail a payment runs on determines which features are available to it. Add or remove pieces as your mix changes, without reintegrating.

    Can we run this for the merchants we manage?

    Yes. The same platform deploys for a single merchant or white-labeled for a platform, agency, or office managing hundreds of them. Your merchants get checkout and portals under your brand, and you get boarding, routing, and reconciliation across the whole portfolio.

    Launch your commerce platform.

    Tell us what you're building. We underwrite the business, connect the processors and payment methods it needs, and hand over one API, one ledger, and a portal for everyone who touches it. Agents and platforms get their own from day one.
