AI Transaction Categorization & GL Coding

The problem

Somebody in your finance team codes the same vendor to the same account, class and department every month, hundreds of times, and has done for years. When they are on leave, coding quality drops. When a new AP clerk starts, it drops further. Reclassification journals at close exist largely to fix coding that was predictable from the start.

NetSuite gives you the tools to reduce this — default accounts on vendors, item mapping, memorised transactions — but they are static rules that cover the easy cases and break on the rest. A vendor who supplies both consumables and capital equipment cannot have one default account. A shared services cost that splits across four departments by a shifting ratio cannot be a static mapping. And nothing in a static rule learns from the corrections your team has already made thousands of times.

What ECOSIRE builds

We build a coding assistant trained on your own posting history and embedded in the transaction forms your team already uses. All SuiteScript, custom records and configuration ship to you as an SDF project or unmanaged bundle you own.

Learning from your history

A Map/Reduce script builds the training set from your posted history — Vendor Bills, Expense Reports, Credit Card Charges, Journal Entries and Checks — pairing each line's descriptive signal with the coding it ultimately received. Features include vendor, the line memo and item description text, amount band, currency, subsidiary, the entity's own coding history, the requester or expense submitter, and any custom segment you use in coding. Crucially, the target is the final coding after reclassification, so the model learns what the answer should have been rather than what was first entered.

A classifier is fitted per coding dimension — account, class, department, location, and any custom segment — because those dimensions are frequently driven by different signals. Each prediction carries a calibrated confidence score, and the training set is versioned so you can see which history a given model generation was built on.

Suggestion at entry

A User Event and client script pair puts the suggestion in front of the person coding, on Vendor Bill, Expense Report, Credit Card Charge and Journal Entry forms. Above your configured confidence threshold, the line is pre-populated and visibly marked as a suggestion. Below it, the top candidates are offered with their scores and the user picks. Nothing is ever silently changed without a marker, and thresholds are set per dimension and per subsidiary — you may be happy to auto-apply department and want a human on every account.

Every suggestion, acceptance and rejection is written to a custom Coding Suggestion record. That record is both the audit trail and the next training set: a rejection with a correction is the single most valuable data point the system produces.

Bulk and inbound coding

For volume paths — bank feed lines, imported card statements, EDI-originated bills — a Scheduled Script or Map/Reduce codes in bulk under the same thresholds, routing anything below confidence to a review queue rather than posting it. A RESTlet exposes scoring to upstream systems, so an OCR or AP-capture tool you already run can request coding before the transaction ever reaches NetSuite, and a SuiteTalk REST integration lets externally-created transactions be scored on arrival.

Controls and governance

Approval routing is respected, not bypassed. Where you use SuiteFlow, suggestions feed the workflow rather than short-circuiting it, and we can route auto-coded transactions above an amount threshold to an approver regardless of confidence. Roles and permissions control who may change a threshold, who may accept an auto-code, and who may retrain. Model performance — acceptance rate, correction rate and accuracy per dimension, per vendor and per coder — is reported through saved searches so finance can see where the model is reliable and where it is not, rather than trusting it globally.

Retraining runs on a schedule you set, incorporating recent corrections. Each generation is recorded with its training window and its measured accuracy, and rolling back to a previous generation is a configuration change, not a rebuild.

Who this is for

Finance teams processing enough AP and expense volume that coding is a recurring time cost — typically hundreds of coded lines a month upward — with at least a year or two of consistently coded history to learn from, and a chart of accounts plus class/department/location structure that has been stable enough for past coding to be a valid guide. If your chart of accounts was restructured last quarter, we will want to talk about which history is usable.

How delivery works

1. Scoping call. We examine your posting history, coding dimensions, subsidiary structure, the transaction types in scope and your current approval flows. We look at real records in your sandbox and assess whether history quality supports the accuracy you need. 2. Fixed quote. Written scope, fixed price, delivery window. Typical build is one working week from signed scope. 3. Build. Developed against your sandbox with your real coded history. 4. Install in test. Sandbox install, then a shadow-mode run: the model predicts coding on real transactions and records what it would have done without changing anything, so you can measure accuracy per dimension before it touches a live posting. 5. Production install. SDF project or unmanaged bundle, with thresholds deliberately set conservatively at first and raised as the shadow-mode and live evidence justify it. 6. Support. A defined post-go-live support window stated in the quote, covering defect fixes and threshold or retraining adjustments.

We do not quote an accuracy percentage before seeing your data. Shadow mode gives you the real number on your own transactions before you rely on it.
