Conversion reconciliation
Reconciliation readybefore the first mock.
Reconciliation is typically the slowest step in each migration, and automating it takes risk out of every mock, rehearsal, and conversion weekend. We bring accelerators and lessons learned from prior digital platform conversions, and AI-accelerated data mapping that never puts customer data at risk.
Why it matters
Reconciliation sets the pace of every mock.
The bank is conversion-ready when the migration balances. An ad-hoc reconciliation and validation process can be the highest risk, and slowest step in any conversion.
Run it every mock, and rehearsal.
Counts, totals, the general ledger, account-level checks and business validation run on each mock and again on conversion weekend.
Identify data problems fast.
The sooner every record is compared, the sooner fixes reach the source data, while there is still time to rehearse them.
Go/no-go based on evidence.
Finance, operations, risk and audit sign on reconciliation evidence, and without it the weekend waits.
| Built during the program | What we bring |
|---|---|
| Balancing scripts written during the first mock | Automated balancing, ready before the first mock |
| Spot checks on a sample of accounts | Every account compared, field by field |
| Exceptions in a spreadsheet | Exceptions grouped by rule and tracked to closure |
| Entitlements checked by logging in as a few users | Every user, subuser, entitlement, limit and template compared |
| Sign-off evidence assembled at the end | Evidence packs produced on every mock |
Built on prior conversions
What we bring to your reconciliation.
Our practitioners built and used these capabilities on prior conversions, and adapt them to your platforms and data. They are not a product we license.
Balance and compare
Automated balancing
Record counts, control totals and general ledger tie-out, scripted once and rerun on every mock and on conversion weekend.
Account-level comparison
Every account compared field by field between source and target, with exceptions grouped by the rule that explains them.
Parallel calculations
Interest, fees and statements recalculated on converted data and compared with the old platform's results.
A comparison data platform
Source and target data replicated side by side in a cloud data warehouse, so questions are answered by query instead of by hand.
Digital banking and treasury
Digital platform reconcilement
Entitlements mapping, subusers, templates, limits, import maps, address books, legacy reporting and the other complex treasury functions, reconciled between the old platform and the new.
Treasury entitlements
Every company, user, right, limit and approval chain compared, so nobody arrives with less access than they had, or more.
Payments in flight
Recurring, future-dated and pending payments checked to run exactly once across cutover.
Rules and evidence
Reusable mapping rules
Mapping templates, code translation tables and data-quality rules carried from prior conversions, adapted rather than written from zero.
Evidence and sign-off
Reconciliation reports, exception tracking and audit-ready sign-off packs, produced on every mock rather than assembled at the end.
AI-accelerated data mapping
Faster source-to-target mapping, without putting customer data at risk.
Conversions spend weeks mapping fields, codes and tables from one platform to the next. We use AI to draft those mappings, under controls your security, risk and audit teams can sign off.
What AI accelerates
- Drafting source-to-target field mappings from both platforms' schemas and data dictionaries
- Proposing code translation tables: transaction codes, product codes, entitlement types
- Flagging likely gaps and conflicts for a practitioner to resolve
- Keeping the mappings consistent from mock to mock as definitions change
How customer data stays protected
- It works from metadata: schemas, field definitions and data dictionaries, not customer records
- It runs only in environments your security team approves; sensitive data is never sent to a public AI service that keeps or learns from what it sees
- Every proposed mapping is reviewed and signed by a practitioner before it is used
- Every suggestion and every decision is logged for your risk and audit teams
The result is held to the same standard as any other mapping, and the reconciliation on every mock proves it.
How it runs
Reconciliation runs on every event,from the first mock to the final production go-live.
It is the same each time, so rehearsals compare like for like and the exceptions fall mock by mock.
- ReadyBefore the first mockRules and tooling stood up from prior conversions, mapped to your products and platforms.
- Mock 1Counts, totals and the first full exception list, grouped by rule.
- Mock 2Account-level comparison and the first parallel calculations; data fixes land at the source.
- Mock 3 and dress rehearsalMock 3 confirms every migration code change landed. The dress rehearsal, with no code changes since, runs on the weekend's timing and produces the evidence packs for sign-off.
- The weekend and hypercareThe same checks on conversion weekend, then daily until balancing is routine.
Illustrative exceptions by rehearsal for a large conversion with a tight window. On a small conversion, a mock 2 that runs fully clean inside the window can be the last rehearsal. Your data sets the counts.
What gets reconciled
Core and digital conversions reconcile different things.
A core conversion proves money and accounts. A digital conversion, from retail and small business platforms to bill pay and commercial treasury, proves people, rights and payments in motion. When you convert both, we reconcile both in the same program.
Core conversion
- Customers, accounts and relationships
- Balances, accrued interest and holds
- Rates, maturity and payment dates
- Fees, stops and escrow
- The general ledger, product by product
- Interest, fees and statements, in parallel
Digital banking, including commercial treasury
- Companies, users and subusers
- Entitlements, limits and approval chains
- Templates, payees and address books
- Import maps and file formats
- Recurring, future-dated and pending payments
- Positive pay and legacy reports
