OpenRecon

OpenRecon is a free tool for reconciling transactions from payment processors and gateways against an internal ledger. It reports mismatches and missing transactions. Matching first uses shared IDs or references; unmatched rows are then compared by amount, currency, and date window. Amounts use Python Decimal rather than floating-point arithmetic. Presets are available for Stripe, Adyen, PayPal, Razorpay, Braintree, and Square, with column auto-detection or explicit mapping. The input consists of two CSV files, and the tool offers a command-line interface and Python library. Results can appear in console summaries or optional JSON and CSV reports. When discrepancies exist, the CLI exits with a non-zero status, which supports scheduled tasks and CI workflows. The maker says OpenRecon runs locally without network calls, so ledger and processor files stay on the user's computer. It requires Python 3.9 or later and has no dependencies beyond the standard library. The maker describes its intended users across payments, finance, accounting, engineering, operations, marketplaces, audit, and internal-tool teams.

OpenRecon offers local CSV reconciliation with both command-line and library interfaces. Its stated limits, including two-file input and planned support for several reconciliation cases, define the scope to consider.

It suits payments, finance, accounting, engineering, operations, and audit teams that reconcile transactions from two CSV files. Developers can also use its Python library or CLI in internal tools and automated workflows.

OpenRecon is a free, local reconciliation utility for payment data and internal ledgers. It suits finance, operations, and engineering teams that can use Python or a command line, especially when keeping files on-premises matters. The trade-off is a deliberately narrow two-CSV workflow rather than a broad settlement platform.

Overview

OpenRecon compares processor or gateway transactions with an internal ledger and reports mismatches and missing transactions. It first uses shared IDs or references, then evaluates remaining rows by amount, currency, and a date window. That sequence handles obvious links before applying broader matching rules, making it practical for routine file-based checks.

Amounts use Python's Decimal type instead of floating-point arithmetic. For reconciliation, that is a meaningful safeguard against rounding artifacts that can create false differences. Processing is local, with no network calls according to the maker, so ledger and processor files remain on the user's computer.

Key features

Processor mapping and matching

Presets for Stripe, Adyen, PayPal, Razorpay, Braintree, and Square provide ready-made starting points. Column auto-detection can reduce setup work, while explicit mapping accommodates CSVs that do not follow a preset's layout. The identifier-first approach is strongest when systems share stable references; amount, currency, and date-window matching covers rows lacking those references but may require closer review in ambiguous data.

CLI, library, and reports

A command-line interface and Python library let teams run reconciliation manually, embed it in internal tools, or schedule it as part of operations. Console summaries give a quick result, with optional JSON and CSV reports for downstream handling. The CLI returns a non-zero status when discrepancies exist, a useful signal for scheduled jobs and continuous-integration pipelines because an exception can fail a workflow without custom parsing.

Local, lightweight operation

Python 3.9 or newer is required, with no dependencies beyond the standard library. That keeps deployment comparatively simple for teams already operating Python. The scope is two CSV input files. Many-to-one matching, multi-currency settlement, refund and chargeback handling, and HTML reports are planned rather than part of the current workflow, so organizations with those requirements should not treat OpenRecon as a complete settlement system.

Pricing

There is no paid tier, subscription renewal, or trial period to manage. The free plan is a natural fit for teams that can run local software and are comfortable owning their deployment and workflow. It does not provide a hosted service or a broader commercial tier for capabilities outside the current two-file scope.

Platforms

OpenRecon is offered through an API and as self-hosted software. Its listed requirement is Python 3.9 or newer, and standard-library-only dependencies favor controlled servers, developer environments, and internal automation over end-user desktop deployment.

Who it's for

Payments, finance and accounting, engineering, operations, marketplace, and audit teams can use it for processor-to-ledger checks. It is particularly well suited to technical groups embedding reconciliation in internal tools or enforcing discrepancy checks in scheduled and CI workflows. Teams needing refunds, chargebacks, multi-currency settlement, or relationships involving more than two files should look beyond this focused design.

Pros and cons

Pros

• Local processing: Files stay on the user's computer and the tool makes no network calls, supporting in-house data handling.
• Money-safe arithmetic: Python Decimal avoids floating-point calculations in amount comparisons.
• Automation-ready exit codes: A non-zero result on discrepancies fits scheduled jobs and CI pipelines.
• Useful processor coverage: Six built-in presets, auto-detection, and explicit mapping address common CSV formats.
• Flexible integration: Both a CLI and Python library support scripts and embedded internal tooling.

Cons

• Two-file input: The current workflow is limited to comparing two CSV files.
• Important cases are pending: Many-to-one matching, multi-currency settlement, refunds, chargebacks, and HTML reports are planned improvements.
• Technical operation required: Self-hosting and Python use make it less suitable for teams seeking a managed, browser-first product.

Alternatives

Choose SahiSay Reconciliation instead if you need Android, iOS, web, or Windows access, a daily free quota of five reconciliations, unlimited transactions per file, and PDF export; its Pro plan costs ₹1,499 a month.

Settler is a better fit when an open-source option with self-hosting, local evidence and replay traces, and up to 10,000 monthly reconciliations is preferable; its Open Source plan is free.

Pick speedRecon for a web-only, single-user workflow offering three reconciliations per month and uploads of up to 300 rows per file at no cost.

FIS Data Integrity Manager is a paid web alternative.

BankRecon is a paid web service with a free trial and a Standard plan for one to three entities.

Eko Recon offers free API, self-hosted, web, and Windows options with pricing not published.

Reiterate OS is a paid API and web option with a €19-per-month Mini plan for invoice processing workflows.

Verdict

Choose OpenRecon if you need a free, local, scriptable way to reconcile two CSV files and value precise money arithmetic and automation-friendly results. Its main reason to look elsewhere is scope: teams handling complex settlement relationships, refunds, chargebacks, or multi-currency data will need a broader reconciliation product.
