How it works

From incoming document to completed AS/400 (IBM i) entry

Each document becomes a piece of work that can be tracked from the moment it arrives to the moment somebody approves it.

Information typically read

  • Customer or supplier number
  • Invoice or order number
  • Product codes
  • Quantities
  • Prices
  • Dates
  • Tax codes
  • Claim or policy numbers
  • Shipping references
  • Account information

The seven steps

Your screens, your business rules, your approval — nothing about the underlying application changes.

  1. Step 1The document arrivesThrough email, SFTP, cloud storage, an API or another agreed source.
  2. Step 2LegacyBridge reads the informationCustomer and supplier numbers, invoice and order numbers, product codes, quantities, prices, dates, tax codes, claim and policy numbers, shipping references and account information.
  3. Step 3The data is checkedMissing information, incorrect formats, unexpected values and your other business rules.
  4. Step 4The correct AS/400 (IBM i) screens openThe same menu path and screen sequence an employee would follow.
  5. Step 5The fields are preparedThe information is placed into the required AS/400 (IBM i) fields.
  6. Step 6A person can review the transactionYour employee compares the prepared transaction with the original document and decides whether to approve it.
  7. Step 7The result is recordedWhat was read, what was entered, what was flagged and who approved the transaction.

The old screen stays. Your team works from the clean one.

LegacyBridge follows the same menu path and screen sequence an employee would use. No new API is required.

Why the Proof Is Low Risk

See it work before giving it control

No automatic final submission

During the controlled proof, LegacyBridge can stop before the final AS/400 (IBM i) action. A person checks the document, extracted information and prepared fields before approving the transaction.

No forced cutover

There is no moment where the old process is switched off and the new one suddenly takes over. Your existing process remains available throughout the test. You can test LegacyBridge on one selected transaction while the rest of the team continues working normally.

No changes to the core application

LegacyBridge works with your existing AS/400 (IBM i) screens. The proof does not require changes to your RPG or COBOL application.

Start with one document

You do not need to provide a large dataset or open a full department to automation. Start with one invoice, one claim, one order or one work document.

Use your real business rules

The proof can follow the same checks, screen sequence and approval rules that your employees use today.

Keep a person in control

Every transaction can require human confirmation. LegacyBridge does not have to be allowed to complete work independently during the test.

Work within an approved security setup

Your technical and security teams can agree on the environment, access rights, permissions and data-handling rules before the proof begins.

Stop at any point

Testing one process does not commit you to a wider rollout. The proof exists to answer one practical question: Can LegacyBridge complete this real process correctly and safely?

Getting started

Seven steps from first call to a decision

Every one of them keeps your current process running.

1Choose one documentSelect an invoice, claim, order, work order or other document your team currently enters manually.
2Show us the current processWhich AS/400 (IBM i) screens your employee uses, which fields they enter and which checks they perform.
3Agree on the security and safety rulesEnvironment, access, permissions, data handling, approval step and what LegacyBridge is allowed to do.
4Run the controlled proofLegacyBridge reads the document and prepares the AS/400 (IBM i) transaction. It stops before the final submission.
5Review the resultYour employee compares every field with the original document.
6Approve or reject itThe transaction moves forward only after human approval.
7Decide based on evidenceTest more documents, automate the workflow or stop. No wider rollout to commit to first.
