Payment reconciliation platform · engineering partner
Payment ledger and reconciliation development,
engineered as a system you own.
TrustChange builds payment reconciliation software for EU-facing PSPs, EMIs, neobanks, marketplaces and licensed VASPs. We engineer the ledger, the reconciliation engine, the adapters into your rails and the break workflow as bespoke code under your brand — not a SaaS licence with a per-transaction fee. You get a payment reconciliation platform your engineers can extend, your operators can run and your auditor can read.
- EU-based engineers
- PSD2-aware delivery
- PCI DSS scope kept small
- GDPR-aware storage
What "reconciliation software" means here
A payment reconciliation platform that fits your rails, not a generic SaaS
Most payment reconciliation software products assume a generic rail mix and hide the matcher behind a licence. We work the other way. TrustChange is a payment ledger and reconciliation development partner: your sources, your rules, your ledger, your code. What you buy is engineering — a reconciliation engine and a break workflow engineered against the reality of your close cycle.

Subsystems
Three subsystems inside every reconciliation engine we build
A reconciliation platform is not one service. It is a ledger, a matcher and an operator surface that must agree on every cent. We build the three together, on one plan, with one team accountable end to end.
-
01
Double-entry ledger
The source of truth for every movement across cards, SEPA, open banking and on-chain rails. Idempotent writes, replayable from the event log.
- Per-asset accounts
- Idempotent postings
- Event-sourced audit
-
02
Reconciliation engine
The matching core that pairs your ledger with acquirer files, PSP webhooks, bank statements and on-chain reads on a schedule you control.
- Two- and three-way matching
- Tolerance and fee rules
- Scheduled and on-demand runs
-
03
Break workflow
The operator surface: aged queues, assignment, notes, resolution codes and re-runs. Analysts see why a break exists, not just that it does.
- Break aging & SLAs
- Case notes & re-run
- Root-cause codes
Stack
What sits behind automated payment reconciliation software
Seven layers, one system. Every layer names an owner, a control and a piece of audit evidence — nothing is left implied under the "automated" label.
Delivery patterns and evidence: how we deliver. Wider platform view: fintech infrastructure.
| Layer | What we build |
|---|---|
| Ingestion | Adapters for card acquirer files, PSP webhooks, SEPA statements, open-banking APIs, on-chain reads and internal event streams Every source is versioned; a rerun on the same input is deterministic. |
| Normalisation | One canonical transaction shape across rails with fee, FX, timing and refund fields resolved Adapter authors add rails without touching the matcher. |
| Matching | Rule-based matcher with amount, currency, reference, fee and time-window tolerances Rules are configuration, not code — reviewable in the admin console. |
| Ledger posting | Double-entry postings for confirmed matches, provisional entries for holds and pending Every posting carries a source id and a rule version. |
| Break management | Break case files with aging, ownership, notes and resolution codes SLAs, escalation and re-run of individual cases without a whole batch re-run. |
| Reporting & exports | Daily close pack, exceptions report, GL export and auditor bundle Finance, ops and external auditors read the same source of truth. |
| Controls & access | Role-based access, four-eyes for manual adjustments, tamper-evident logs Every override is who / what / why / when, retained per your policy. |
Break path
From ingest to a clean close
Every source in the payment reconciliation software goes through the same gates before a posting is written or a break is opened. Speed comes from tuning the pipeline, not from skipping a step or trusting the input.
- 01
Ingest
Continuous
Files, webhooks and API pulls land in a staging area with a checksum and a source-run id.
- 02
Normalise
Per source
Rows are mapped to one canonical transaction shape and enriched with rail metadata.
- 03
Match
Scheduled + on-demand
The reconciliation engine pairs entries under rule tolerances; matches post to the ledger.
- 04
Break
T+0 to T+1
Unmatched entries open cases with owners and SLAs. Analysts resolve, re-run or escalate.
- 05
Close & report
Daily / month-end
Confirmed positions publish to finance, GL and the auditor bundle. Nothing is retro-edited.
Delivery
How we deliver ecommerce payment reconciliation software
Five steps, in this order. Reconciliation work runs inside the product backlog — no separate finance phase bolted on before month-end, no big-bang release of an untested reconciliation engine.
- 01
Scoping
Weeks 1–2
We map rails, sources, close cycle, chart of accounts and control expectations. Output: a scope, a control map and a costed plan.
- 02
Architecture
Weeks 3–4
Ledger topology, matcher rules, adapter contracts and export schemas written down first. Auditor requirements shape the design, not a later patch.
- 03
Build
Two-week sprints
Adapters, matcher, break workflow and exports ship in slices. Each merge runs tests, static checks and a dependency scan.
- 04
Hardening
Before cut-over
Replay against historical files, load work, failure drills and a third-party review window. Cut-over is rehearsed with your finance team, not assumed.
- 05
Launch and run
Cut-over + ongoing
Named engineers on 24/7 cover for the first close cycles. Runbooks, dashboards and the audit bundle are handed to your team on day one.
Engagement
Four ways to buy your reconciliation platform build
Same engineers, same standard. Only the commercial shape changes.
-
Fixed-scope build
A defined ledger and reconciliation engine at a fixed price and date. Best when rails and cadence are settled.
-
Dedicated team
A standing squad with a lead. Best for long roadmaps and new rails each quarter.
-
Staff augmentation
Senior engineers inside your team. Best when you already own the plan and need reconciliation depth.
-
CTO advisory
Architecture and buy-vs-build review before you commit. Best at the design stage.
Questions
FAQ: payment ledger and reconciliation development
Six answers up front on scope, ownership, rails, finance-stack fit, controls and support. Bring the rest to the call.
What do you mean by payment ledger and reconciliation development, exactly?
We engineer a bespoke, client-owned payment reconciliation platform for you — a double-entry ledger, a reconciliation engine, adapters into your rails and an operator surface for breaks. It ships as source code in your repositories, with the IP assigned to you. There is no per-transaction fee, no shared multi-tenant backend and no vendor gate between you and your close cycle.
How is your build different from an off-the-shelf payment reconciliation software product?
Off-the-shelf reconciliation software is packaged for a generic mix of rails and hides the matcher behind a licence. TrustChange builds the rules, the adapters, the break workflow and the ledger against your actual sources — card acquirer files, PSP webhooks, SEPA statements, open-banking APIs and on-chain reads — and hands you the code. A bespoke reconciliation engine takes longer up front, but you keep every rule, every adapter and every posting decision.
Which rails and sources can the reconciliation platform match against?
The reference build covers card acquiring files (Visa/Mastercard/Amex acquirer reports), PSP webhook events, SEPA and SEPA Instant statements, open-banking pulls and on-chain reads for the digital-asset side. Ecommerce payment reconciliation software adapters cover the same shape — cart events, PSP capture events and acquirer settlement — with fee, FX and refund fields resolved into one canonical transaction row before matching.
How does automated payment reconciliation software fit with an existing finance stack?
The engine posts to a double-entry ledger and exports to your general ledger and warehouse on the schedule you set. Finance keeps its close process; operators work breaks inside the admin console; auditors read the same daily close pack and exception report. Nothing about your GL, chart of accounts or period locks is silently rewritten — every posting carries a source id, a rule version and an operator id where applicable.
How is a payment gateway reconciliation software build engineered for PSD2, AML and GDPR?
TrustChange is an engineering partner, not a law firm — your compliance and audit teams set the policy; we ship the controls and the evidence. That means tamper-evident logs, role-based access, four-eyes on manual adjustments, PSD2-aware fields on card and open-banking flows, sanctions-screening hooks where required and GDPR-aware storage with retention rules. Nothing about licence status, opinions or approvals is claimed on your behalf.
Do you also run reconciliation after launch, or hand it over?
Both are on the table. Most clients start with named TrustChange engineers on 24/7 cover during the first close cycles while their own team ramps up, then take the platform in-house with runbooks, dashboards and an on-call handover we author together. Some keep us on as a dedicated development team or on staff augmentation for new-rail adapters and rule roadmap work.
